Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

For the past 2-3 years the security light will come on and flash about 10 minutes. During that time I have to sit with the key in the ignition and the ignition switched back until the security light stops, which then the care will start. About a month ago same constant problem except now after the security light stops flashing car won't start at all. I've gotten new battery and had alternator checked and both are good. The security pass code dealing with the keys or some mess I was told which will cost $500.-$600. Omg!!!!! really. Is there a recall or something for this. GMC please do better. Last american made car that I will purchase.

While driving at night on I127 highway, with my dim lights on and cars passing me, my dims go blank. Nothing. I had to quickly pull over and make adjustments to find the problem. After about a dozen episodes of these I find that my bright lights would still operate. After I'd get home I would shut the engine off and wait a few minutes and restart the engine and my dims would come back on !!!!! I have cleaned the little signal switch on the front dash but they still go off at any time of the night. I have come close to a few accidents. Please help ! I have talked with several mechanics and rookies but they were stumped. This is a safety issue and should be addressed.

Went to turn on the car; all lights locks radio windows worked. When I turned key to on position car would not turn on. Security light and check engine lights would come on. Car wouldn't turn on for ten minutes then it turned on. Also, while driving security light will come on and stay on until car is turn off and back on. Sometimes security light will stay on. In addition, to security light and car not wanting to turn on, turn signals will randomly stop working and I have to turn hazard lights on and off to get turn signals to work again.

The contact owns a 2002 Chevrolet Impala. The contact stated that while driving 50 mph, the headlights malfunctioned when switching from low beams to high beams. The manufacturer was notified, but offered no assistance. The vehicle was not repaired. The contact was now experiencing another new safety concern in regards to the pass lock, where the components were wearing out. The security system would not recognize the key when it was inserted into the ignition. This locked the contact in the vehicle and prevented it from starting. The vehicle was not diagnosed or repaired. The vehicle had not been driven since this pass lock failure. The VIN was not available. The failure and current mileages were 102,000.

Turn signals work intermediately. This is a very common issue with Impala. Very dangerous when I signal I don't know if it is going to work. I have almost caused multiple accidents because of this issue. I complained multiple times to the dealer but they claimed nothing was wrong. As soon as I hit the 100,000 mile mark they all of a sudden have a solution. This should be fixed by the dealer because of the number of times it's been reported. There is obviously something going on with the switch.

Air bag light has been diagnostic by, authorized Chevy dealer, as needing to be replaced. Estimated cost of the part $703 plus tax and shipping. This is a part that should last the life of the vehicle, especially at that price. I was told, there is recalls in reference the safety air bag system for 2002 Chevy Impala's.was this part included in the recall ? if not, this part should be, or at least made available to the end customer at the manufacturers cost. I am a continues General Motors customer since 1987. This 2002 Impala has given me electrical problems since I purchased it. I am at the point of looking at different product lines. I am very interested in GM response to this.

After starting the car blower motor wont work cruise light stays on mirror cluster don't work until 15 min then everything will work but when using the cruise it will stop working but light stays on after time gauges cut out and then come back on and all problems slowly become worse with time. Have reason to believe its the ignition switch.

Security system failure. Vehicle would not start. Luckily I was in my driveway when it refused to start. Had to replace body control module, lock cylinder with passlock sensor before car would start. This may not seem like a safety problem, but, when you think about all the places your car could leave you stranded, it's scary. I am not the only one who has had this problem. There are thousands of complaints with this problem on several web sites.this is a fault of General Motors, they know about the problem and have not done anything to help their customers with this problem. They need to come up with a permanent fix for the passlock system and have a recall and fix it once and for all. Average cost for this repair is about $1,000 dollars. The customers who have paid it deserves their money back.

GM vehicles equipped with the passkey system may, and thousands do, experience a passlock system lockout, where the security system prevents starting of the vehicle, even when using the mfr's supplied key. The passkey sensor problem is recurring even after some consumers had dealers replace it. This defect in the passkey II and III as well as the passlock systems on GM vehicles has plagued my vehicle since 3 weeks after purchase. The dealer said I have to replace the passkey sensor, ignition control module, ignition switch, BCM and even possibly the ECM. I have checked with other shops and consumers via online forums and personal interactions, and have come to learn of 1000's if not 10,000's of consumers have this problem, and the dealer recommended repairs/replacements only cover up the problem for about a year. This problem prevents the owner from starting the car, as well as cause it to stall regardless of location or driving condition. This can result in loss of control and possibly leaving a consumer stranded in unsurvivable situations. This is a public safety and a health risk. Even when under warranty, the dealer refused to replace the 'recommended' parts as they were not covered under powertrain warranty, however they cause the vehicle's powertrain to not function or cease function when running just fine seconds prior. GM has been notified of this issue by myself and to no avail, a resolution is unavailable. I had a friend of mine replace over 8 components of the ignition/security system at the dealer for a cost over $2500. The vehicle was 4 months old. My vehicle, at 9 years has had this problem for the past 4. GM needs to recall all vehicles equipped with a passlock/passkey 2-3 system for replacement with a more reliable one. A google search turns up over 138,000 results for GM passkey problems. GM passlock problems turns up over 85,100 results. That is 223,100 results. If I do vehicle specific, that number triples. Chevy passkey problems returns 1,340,000.

Passlock system on 2002 Chevrolet Impala is defectively designed. Failure leaves owner unable to start otherwise 100% operable vehicle. Passlock device replaced in 2008 after complete failure. Passlock device failure again in 2011. GM claims nothing wrong. Issue very widespread and well known to dealers and mechanics.

I got my car on 03/09/2011. I have been complaining to the dealership about the issues I am having with my car. It hesitates to crank, when turning I can feel a popping feeling in the steering. Very often my signal lights doesn't come on. I do a lot of highway driving back and forth to work and this is very dangerous. When hitting my breaks the car sometimes speeds up before slowing down, which can be very dangerous. There is a shortage in the wiring. The low coolant level light stays on, even though they claim they fixed some sensor switch. They also said they fixed my car from leaking brake fluid, but the brakes are sounding worst everyday. I asked them if the brakes needed changing and they said it was fine. The car hesitates when taking off. I just got home from work and not even 30 minutes went by before I tried to leave out and my car would not crank. I have been complaining to the dealership since I got the car and they have procrastinated until the 30 day warranty expired. When calling today the dealership said that I would have to pay for any repairs because the warranty expired. When asking why should I have to pay for repairs, when I have been complaining about these issues since I first got the vehicle, the reply was they are not going to pay that any mind and I would still have to pay for the repairs.

On the ip the ignition key is not functional every once a while and it does require a 10 minutes wait in the vehicle with the key in the ignition before you can fire the engine. This issue been persisting for the last 2 years. I do wonder if this problem been experience with Chevy?
