Chevy has not won any points with me after buying the 2000 Impala LS (NEW). The car has been a "lemon" since day one. Not only that - but all of the problems with the car can be found reported time and again on these message boards. About a year ago, I had the fun issue of the car not starting and when it did start, it would eventually stall at lights and sometimes while driving. Dear hubby replaced the crank shaft sensor and Chevy happily replaced the Pass Lock System (for about 500 bucks). The car ran ok after that but still "pulsed" on the road, causing me to have to let my foot off of the gas and reapply. In general, the car has never been a great ride despite the great comfort and style. The stalling problem appeared again this week. The car died a few times and started right up again early in the week. This morning, on the way to daycare with my 3-month old in the car, the car died and would not restart (GREAT during rush hour!) After about 5 minutes, the car started and I got around the next corner before it died again. The car restarted and died immediately after. Again, after letting the car sit for about 5 minutes, it started and I made it to daycare. Dear hubby took the car and hooked it up to the meter. Good ol' code p0336 came up again. WHAT? How many times does a crank shaft sensor need to be replaced. And when will Chevy take responsibility for putting out such a piece of crap car.

I have been having this problem for a few months now and have been to several mechanics each of which have not figured out the problem. My car randomly stalls while driving and Chevy needs to do something to fix this. Has anyone found the solution to this problem yet, Please let me know, i love my impala and i hate being worried about driving it.

About a month ago I had to do some errands. When I went to start my car it was really rough and sounded very quiet like it had low RPM (no tach) but I'm not totally sure. Ran fine for a few days and then a friend of mine borrowed the car for a few errands and he calls me from the gas station saying my car won't start. I head over and the engine will crank, but it dies right away. If I give it gas it will run but dies when it comes to an idle. I finally got it to work, and when I used it later in the day it was fine. The problem only happened on startup from operating tempurate. Looked on here and thought CKP sensor was the problem since that sensor was somewhat temperature sensitive since it has to be warm to calibrate it. So I had that replaced at the mechanic since I don't have a scan tool to calibrate it. I got back and let the car sit for a few minutes from operating temperature and tried to start it and no problems. When a week, redid struts and brakes, halfshaft and trying to start the car cold Monday Morning wouldn't start. Got home that night and looked at the dealer manual I have on my comp and started going through everything. Checked the map sensor and it was clean. Then I check the IAC (Idle air control valve) and it was very gunky. I cleaned it out and haven't had a problem since (3 weeks). I am going to replace it though because this is a sensitive device and is really not supposed to be cleaned. My car is a former squad, so they idle for hours a day, so the device goes early on those models. Seach for IAC in yahoo and you'll find former Crown Vic Interceptors had the same problem, and Jeep Cherokees have a recall for this device that sites the sames symptoms that we have all been having. The IAC valve it right on the throttle body under the fuel injector sight shield (3800 Series Cover), and all you need to replace it is a torque set screwdriver. Can get from autoparts stores for about $35. If you open up to see the IAC is dirty, this is most likey your problem. It wouldn't hurt to use throttle body cleaner on the whole throttle body MINUS the IAC. DO NOT ATTEMPT TO USE ANY CLEANERS ON THE IAC. It is a sensitive device and should just be replaced. Like I said, I wiped the gunk off of mine but am replacing the unit.

Had the same problem as some of you have with your Impala stalling while driving. Only difference is that, my car would stall up to 3-4 times per day most of the time and as time went on it got worse. The last time it happened was when my wife was driving to work the car stalled a few yards away from a railroad crossing (since she quit driving on expressway), luckily it didn't happen on tracks, no train was coming at that time. She had to wait approx. 25 mins for it to start after trying a few times. The next day the same thing happens but this time it didn't turn on, so she called the dealership and they sent a tow truck. The tow truck driver, when he arrived approx. an hour later, tried to start it but it didn't start either. So, when arrived at the dealership they tried starting it and by then it started. The shop manager, whom I had related this incident to was aware of the situation, so he then assigned a mech to stand by the analyzer monitor while the engine was running. They kept the engine running until it finally died on them again, while the mech was still there, I don't know how long (didn't ask). At this particular time the analyzer indicated that the Crankshaft Position Sensor was the cause of the stall. After further check-up it was found it had a crack on casing (as in earlier model cars that have a distributor cap and won't start if the cap has a hairline crack on it, same effect here). Needless to say it was replaced and is now a month later and it's running just fine. Not a hint of stalling nor anything else. The only thing I would suggest, if I may, is to take your Impala to your favorite auto shop and have them install the analyzer while the engine is running and have someone standby and keep an eye on the analyzer and wait till it stalls, because, as I was told, it does not show a code.

I have had the EXACT same problem with my car. Started in June of 2006. Replaced a few things, did a tune-up. Never could tell if it helped or not because in the beginning it happened maybe once a week. I had a large amount of things replaced in April of 07 because the problem had gotten serious every day, at least once it stalled sometimes it would take me 20 minutes to get out of the driveway. Very stressful. One of the things we replaced was the crankshaft position sensor. I took the car on a road trip (9hrs one way) and back with no problem at all. Didn't happen again.... for a few months in July 07 it started again and was even worse stalling on the highway even, sometimes it would turn off and back on in a second on its own while driving. Had the ignition switch replaced, no fix, had the crankshaft position sensor replaced again... so far (2 months) so good. I wonder if something is causing that sensor to go bad. However now the car is still a piece of crap, with other problems having just popped up. UGH!

about a year ago my husband was following me in my dump truck, him in my impala he pulled up next to me at a light and told me the car stalled when he was driving. really didn't think anything of it until i parked kinda cocked sideways on a crub with the passenger side up on the curb shut my car off then went to start it it would not stay running, it started but would stall unless i gas and brake and put it in gear, hoping that i hit drive after that i left and came back like ten min later parked in the exact same spot and angle and it did it again but then later on level ground did not happen. anyone who is having the stalling problem for the hell of it park your car on that same angle passenger side on a curb and try see if there car does the same! i luckily haven't bent over for the dealers and spent one dollar to fix it because there scam artists and after seeing all of the money some of these people have spent it makes me sick! chevy should be ashamed of themselves and i think they all should get interest on the money they've spent ten fold i bet if this was a gm employees daughter or mother they'd get snappy about fixing the problem..

my 2000 impala would stall going down the road. first trip to dealer found no issues, next day i took it back cuz it did it again that night. then they thought ignition control module. well three days later it did it again. then i finally convinced them to change the crankshaft position sensor and that was over a month ago and no more problems so far! seriously people if your impala stalls while driving and the dealer says nothing is wrong since there isn't a code on the computer for it, don't believe him and have them change the sensor anyway! i spent over $1300 chasing this problem and all it ended up being was a $70 part!

This car has been a mess since the day I bought it. Bought as "dealer" car only to find out from transmission guy and confirmed by engine guy that it was a rent a car fleet vehicle that had been in 2 accidents. Anyway, I had purchased an extended warranty only to be told they couldn't find my info. Luckily I found my signed papers but, had to pay out of pocket and get partially reimbursed from GM. Anyhoo- a right side control arm, several tie rods, a new transmission, automatic window trouble, a new engine, a new starter, numerous other troubles, and now it's doing the stalling thing. I am a single mother with 4 children- one of whom is an infant. This car has drained me financially and I still have one more payment to go. It's a shame- it's such a comfortable and spacious vehicle. It is a danger to myself and my children. Drivers are very aggressive and I don't need to get rear ended or worse. Can anything be done? I am not in a position to get a new car, I'm afraid to buy a beater with more problems to fix but, I work full time to support the kids and need a vehicle. Tell me more about a class action suit. GM should have some sort of responsibility to their customers.

Hi everyone. Well I've had the same problems that all of you had/have. My mechanic switched out a sensor thats called the MASS AIR FLOW SENSOR. so for so good. runs like it was brand new. Now the sensor is located under the "chevy 3800 series engine cover" look for a square device the has the letters "ABC" at the bottom. That so far, has been the pain that has caused all of us some headaches. Best of luck to everyone.

Not only is the car cutting off, the electrical system seems to be problematic such as the thermostat for heating/air conditioning now only operates to the number 4 and the paint is literally falling off the car in patches. Initially when the car starting shutting off while in drive, I had a tuneup. That did not change the situation, so I changed the fuel. That seemed to have helped a lot, but the problem did not go away completely. I went to the Dealer and he said he needed a "Check Engine Light" on in order to assess the problem. DO NOT LET SOMEONE ELSE'S DIAGNOSTIC MACHINE CLEAR ANY CODES IN YOUR COMPUTER. The Dealer needs to see these codes and the other person's machine codes are very different from the Dealer's code so now I am waiting for the check engine light to reappear. I do find that If I let the car run idle after sitting for more than 5 hours, it runs better.

Check fuel injectors to see if injectors are damaged or fuel pump from lack of fuel. Driving with little or no fuel can damage the vehicle's fuel systems. Check entire system.

My car stalls without a notice. I am very concerned about this b/c I am scared it will stall on the freeway and an 18-wheeler might be behind me and kill me. I took my car to the dealership b/c the a/c went out and they replaced the fuel regulator b/c of the recall. Well, about a month later my car started to stall, it starts back up right away but I am scared to drive it. I put in a new gas filter, did a tune up on it and I am about to take it to the dealership so they can clean out my fuel injectors. Chevrolet should do something about this since it is very dangerous.

Car would crank up and shut down. Would run fine after trying to crank but would stall while at Burger King, Highway, and any other place I would drive to. Was told by some d*ckhead it was my injectors so got those fixed. 400 Dollars later and the problem was still there I took it to a another shop and in about two hours they found out it was a bad ignition switch and 350 dollars later she runs like a champ.

Sometimes my Impala won't start after sitting for a brief period (30-90 minutes), it also hesitates while driving, where it feels like it is losing power, and most importantly, it has stalled on me while I am driving upwards of 55 mph on highways. It almost always starts back up after a short period (five minutes), and sometimes immediately starts back up. However, it is a very dangerous condition. I no longer will take my 1 or 3 year old in the car, and have to borrow relatives' cars to take them anywhere. Although I have an otherwise nice car, it essentially useless to me. I have taken it to my mechanic and multiple dealerships several times, and they always tell me it is fixed or they can't find anything wrong with it. Inevitably within days (and sometimes hours) after getting it back, I have the same problem. I have spent hundreds of dollars to get it diagnosed and "fixed", but to no avail. It has gotten to a point, that although I otherwise really liked the car, I am shopping for a new vehicle.

It wasn't my fuel filter, it wasn't my plugs or wires, or my fuel pump, it was the goddamn sensors. Especially on long trips, i would stall while trying to accelerate and sometimes my car would idle roughly and even die when I came to stops, you have to make sure your oxygen gas ratio is right, and the way you do that is with the sensors on these fancy new cars.

The car has been stalling while driving and not starting on occasion. The last time it stalled on a busy street but restarted after several times. The next morning the car would not start and we had it towed to a mechanic. When they went to push the car into the garage of course it started. They checked the computer and saw a sensor error and thought the problem was fixed by replacing the fuel regulator sensor. 6 days later, it wouldn't start again. After a google search, I was surprised that there are other impalas with the same problem. We have enjoyed this car tremendously and have not had any other problems. We'll take it back to the mechanic and see what else he suggest.

Try replacing your CKP sensor (Crankshaft position sensor)! We had the SAME EXACT issues as everyone on this board AND already had the fuel regulator changed per the recall. The repair out the door should cost 200-225 dollars.
We were getting stall while driving and not. Also, intermittent no-start. We were also getting an error code stating bad data was coming from this sensor.
So far no problems after the repair. We were going to do it ourselves but apparently you need to reprogram the main computer afterwards and we did not have this capability. Otherwise, right wheel off, pull off covers, remove belt, impact wrench the crankshaft bolt, pull off the pully and there it is - replace, reprogram. Good luck!

The stalling while driving has been going on now since just before Halloween. Would not start when I got out of the grocery store after picking it up from the dealer (check engine light coming on but will not turn over). Yikes, the ice cream is melting! I go get a friend from across the street and try it one more time and it starts. Whew! Starts all weekend and appears to be running better until Monday morning when I'm on my way to work... poof... stalls while driving but does start right away and I get to work.
I've replaced the plugs & wires, fuel filter and fuel regulator (recall item) and the problem seems to only get worse. I took it to the dealer to have a diagnostic done and no codes came up. The dealer wanted to have his mechanic take it home overnight with the on-board computer but I declined. They said nothing was wrong but noticed my thermostat was staying open (but would not be the reason it stalls). In frustration I took my car home and naturally on the way home from work the next day the car stalls on the way to the freeway and it takes me 15 minutes to get it started again.
I still owe on this vehicle and if this is the end of it's life already, I am completely screwed! It's really a shame, too. I love this car and it has bee relatively problem free for 6 years now. Currently I'm shopping for a new vehicle. With any luck I'll be able to trade this beast in for something more reliable.

My car just one day decided to stall on me while waiting in line at Taco Bell. It happened again about 1 week later, took it to the Chevy dealer they found 1 for stall on deceleration, reprogrammed PCM. A few days later stalled again. I can be just starting to drive or have been driving for some time. It does not matter if I am at a red light or driving 75 mph on the freeway. I can usually start it again while in neutral but a few times I had to wait a few moments until it would start again. I returned it to the dealer and they felt it was the ignition switch (that it was shorting out) switched that out, it stalled the next day. My engine light does not come on so there is no readings. They installed a VDR to record the system when it stalled again but of course they couldn't get a reading from it other than it stalls all together completely. It still stalls sometimes two times in a day and then not again until ten to twelve days later. They have no idea what is wrong with it. If the dealer doesn't know who can know? Anybody? Help!!

About three weeks ago my Impala started hesitating on take off after it warms up. I took it into the shop and they reset the computer. I drove it again for about a week, and the problem started again. I took it back to the shop. They replaced a coil and told me that fixed the problem. Drove it for about four days, it started again. Went back, Wires and Plugs replaced. Drove it for a few more days, started again. I am told that the vehicle keeps having a miss fire on the number four cyclinder. The shop I had it at was not able to fix the problem. I then took it to the Chevy Dealer. It has been there for four days. I am told that they can't fix the problem. This I don't understand. This is a vehicle that chevy builds and sells. Why can't they fix the problem. Has anyone ever heard of this type problem? If so please let me know, Thanks.

I have the same problem EXACTLY as you have all descibed with stalling. I have replaced the Fuel FIlter and ECM. I heard mention a corroded ground wire as being a culprit to this problem but I have yet to find out for sure. So far I have learned that it is not any of the following; fuel filter, fuel pump, starter, ECM, Fuel Injectors. It can't hurt to check the Ground wire for the computer. If you have any suggestions please intercede.

I'm Back!!!!! Fuel regulator solved the problem last year with this same problem stalling. I really can't believe how GM, Chevrolet and the dealerships duck for cover on this issue. Someone is going to lose their life over this defect. Exactly 1yr to the date of being fixed the problem reoccurs. I think all Imapala owners experiencing this problem needs to come together and file a Class Action Suit. I spent over $2,000 of my hard earned money last year trying to solve the problem through several mechanics. Only to fail and lose money. Finally I drove it to the dealer and dropped it off, I told them that I would not be picking up the car until it was fixed. I told them not to call me unless they had a fix. Luckily for me my lienholder also owns the dealership, so I called them and explained the situation. I told them that I was not making another payment until I had a car I can drive. Well they got on the ball because they did not want a car that could not be fixed either. BUT this year I immediately dropped it off and have not heard from the dealer in 2 weeks and I called the finance company to let them know where the car is. I was hoping this car would last until February so that I could get rid of it. I am now willing to except my losses and vow NEVER to buy another GM or American made car. I urge all potential GM/Chevy buyers to stay away!!!!

Started 3 weeks ago. Happens only when engine is warm and when weather is above 65 degrees. Sometimes it starts right up, other time a few tries and other times several minutes. The fuel pump was tested, no problems. Ignition module was replaced, no luck ($380). No codes show up on the computer. Repair shop has no idea how to fix it. Stalled 5 times today alone.

The engine frequently cuts off at all speeds and weather conditions. I have stalled in the middle of six lanes of traffic going 70 miles per hour and while rolling to a stop at a red light. One dealer couldn't find anything wrong and another tried to replace the connections to the starter, but that did not correct the problem. If anyone finds a solution, please let me know

This problem started about 2 months ago after the dealership repaired the recall. It started with the car not wanting to start when the engine is hot. I can start it first thing in the morning with no problems. It takes about 6 tries to get it to start again after being driven. It has now progressed to stalling while driving, it just dies with no warning. I have been to the dealership as well as contacting Chevrolet as well. I have also taken it to a notable repair man who is a close friend. None of them can find a source to this problem. This is a safety hazard and needs to be addressed seriously before someone gets killied because their car stalls in the middle of the highway.

We encounted stalls shortly after acquiring this auto. The dealer replaced the starter and said the problem was fixed. One week later, the car stalled again. We took the car back to the dealer. They could not duplicate the problem but they suggested the fuel injection service. We paid almost $500 for that. A few weeks later, the car stalled again! We took the car back to the dealer. They still could not duplicate the problem so they replaced the fuel pump. Three weeks later, you guessed it, the car stalled! If anyone has figured out what needs to be done to repair this problem, please contact me. At this point, we are afraid to drive the car because our lives could be in jeopardy. Several times we've been driving 55 mph on the expressway when the car just died. The car is unsafe to drive until this problem is resolved.

I can be driving down the road with no warning my car dies. I have tried to restart the engine, but I have to wait at least 20 min. before it starts. It starts right up as if nothing had happened. The dealership has checked the car several times and can't find anything causing the problem. It has died around ten times. Luckily a semi has not smashed me to bits!!!
Is there anyone out there that is having or has had this type of problem with their Impala? What did GM do to correct the problem? Did they offer you any compensation?
