2001 Oldsmobile Alero ignition switch. The consumer stated the ignition switch was replaced in November 2010, due to the vehicle stalling when placed in reverse. Also, none of the gauges and dash lights worked, the fuel pressure regulator and head gasket were replaced.

The contact owns a 2001 Oldsmobile Alero. The contact stated was driving 40 mph when the vehicle stalled without warning. The failure was experienced numerous times when driving at any speed. The vehicle was taken to a local repair facility where the fuel filter, battery, ignition switch and starter were replaced. The computer was reset but the failure persisted. The vehicle was taken to the dealer who performed a diagnosis but was unable to locate a failure code. The vehicle continued to stall. The failure mileage was 100,000 and the current mileage was 143,000.

The contact owns a 2001 Oldsmobile Alero. The contact stated that after several attempts, the vehicle would not start. The vehicle was taken to the dealer where he was advised the vehicle was not responding because the security system was under the impression the vehicle was stolen. The contact advised the failure would occur intermittently and when doing so, the security warning light would illuminate on the instrument panel. In addition, when sitting idle with the engine running, the vehicle would occasionally stall. The vehicle had not yet been taken to the dealer for a diagnostic. The failure mileage was 135,000 and the current mileage was 136,000.

Alero 6-cyl

  • 85,000 miles
2001 Oldsmobile Alero 3.4L V6 - engine racing - high idle 2004-2010 this has been an off and on problem the entire time I have owned the vehicle the past 6 years and might happen for 2-3 weeks and then not again for a few months. When I start my car it will be idling at 3,500 rpms or more, if I put it in drive it will go back to 1,500 rpms, but the car will start to accelerate by itself (the accelerator is not being pushed and is not stuck). It takes about 20-30 seconds if on flat ground, but the car will get up to 55mph by itself. If I am going down hill it goes even faster. If stopped at a stop light the engine sounds like it is trying to go 60mphs. Sometimes the problem ceases if I shut the car off and restart, but this does not always work. I think it is highly unsafe and with all of the recent Toyota problems I think this should be investigated as one of my college friends has a sister with an Alero that has had the same problem. Please let me know if there has been something done already or if you have heard similar complaints. Thank you.

01 Alero will turn over but not start. First incident was in 2006 replaced fuel pump and fuel filter. Some days it will start others it will not. It also has died while driving twice. Once on the highway and once in town. I was driving across the street with my son and the car died luckily I coasted out of the line of traffic. For the past week it has only started once out of multiple attempts to start it. It shows cam sensor, crank sensor, passlock, codes when diagnostics ran. Other sites have had same issue with nothing being a permanent solution to problem. Car needs to be recalled.

My girlfriend bought a 2001 Oldsmobile Alero from a dealer with a 30 day warranty. The cars antifreeze mixes with the oil (head gasket). He never fixed this and dissapeared on us. This was in March 09. I was told that I might be able to contact GM and they might be able to fix this problem. I've read online that this car was recalled because of numerous problems. Please contact me kema, cornell thanks.

Since Feb. My car has been in for repairs 4 times. I bought the car used in Sept. 05 and almost immediately noticed there was a problem when the window would not roll down and the temp. Gauge went on hot (and the car was not). I took it in to the dealer and they of course found nothing wrong since the computer they use to diagnose problems wasn't registering anything. Not quite a month had passed when I started to have difficulty starting the car, a few days later the car stalled while driving in a.M. traffic on the fwy. It was taken to the dealer again, they stated it was cpc computer had to be reprogrammed and the igniter had to be replaced. On the way home after picking up the car, it stalled again, and would not restart. Again the next day it was taken in and the ignition switch was replaced. A few weeks pass and the same problems start to occur, this time when it was there, nothing could be found. This is a potentially a very dangerous problem, this time again driving on the fwy. The car stalled, I made it to the shoulder of the road, the car again as usual would not restart, next time this happens I may not be as lucky. My car is at the dealer currently and they cannot seem to find out what is wrong. In reading other numerous complaints this obviously is a problem. Who is responsible" does someone have to killed before GMC does something about this"

2001 Alero (2 dr. Coupe) I have been on several sites and am finding many Alero owners having the same problems that I have encountered over the last couple of years. Fuel pump, wheel hub assemblies, intake manifold gaskets, power window failure(grinding/breaking clips/regulators), serv engine and traction control lights constantly on, electrical problems, brake problems etc. It is my belief that olds knew they weren't making this car anymore, and sent a sub-par product out into the market "hoping" to get away with as few recalls as possible. I have numerous complaints filed with olds and General Motors. General Motors has gone way out and offered me a $500 certificate towards the purchase of a new vehicle. Give me one reason I should go through another nightmare like this one. Recalls have never been issued on any of these complaints because it would probably cost millions of dollars for them to fix the problems. I constantly wait to see if any class action suits involving these vehicles occurs as I will be one of the first to jump in. What's the saying..."if it looks like dog crap and smells like dog crap don't step in it, it's probably dog crap". there's a defined problem with these vehicles and GM should be taking responsibility for them.

2001 Oldsmobile Alero intake manifold problem. The consumer had discovered a coolant leak. The consumer stated GM issued an improved gasket to avoid future problems with the engine. The consumer believed it GM was aware of the problem why did the expense have to fall on the consumer. The power steering was replaced.

Alero 6-cyl

  • miles
The technician informed the consumer about a recall on the vehicle, but the consumer never received a notice from the manufacturer. The vehicle would not start right away. There would be several tries but the vehicle would never "crank over." The engine vibrated when the A/C was used, the fuel gauge was inoperative, the front windows would not roll down, the rear handles felt like they were sticking, there was a burnt oil smell, and after several times of starting the vehicle it would run rough. The master switch, A/C compressor, crank sensor, fuel pump, fuel tank, hazard switch, and the window regulator were replaced. The mechanics repositioned a wire harness from the crank sensor and replaced the pressure control solenoid. The turn signals stopped working in traffic in which there was almost an accident. The antenna was replaced because the radio signal would go out every time the rear defroster was used (this did not solve the problem). The back window had to be completely replaced to solve the antenna problem. The water pump was replaced because the seal for the coolant leaked.

One month after purchasing the vehicle I had it back at the dealer for seatbelt not retracting properly. The buttons keep breaking off. Had the rear defroster replaced, the A/C had to be fixed, the brakes and rotors replaced, turn signal switch had to be replaced. The gas gauge currently is not working. There has been so many repairs on this vehicle I can't keep track any more. Continue to have a problem with the car shaking when I have been driving it for a while. Dealer acknowledges there is a problem but has no idea what is causing it. This car is my worst nightmare. I have been to the dealer so many times I lost count.

This complaint is in regards to problems my wife and I are having with our Oldsmobile Alero. We initially used the better business bureaus's autoline arbitration process and although the arbitrator said that the car qualified for the Ohio lemon law, he thought that there may have been a misunderstanding between us and the dealer. What a joke. If you listen to the audio tape of the hearing it is obvious that General Motors was aware of the problem. The following is part of the initial letter that was sent to the better business bureau since you have a restriction set on how much info can be supplied here. Please note that the car is paid for. Date: 08/18/2003 re: William G. marsh 2001 Oldsmobile Alero  odometer reading = 9198 possible violation of the Ohio lemon law better business bureau (B.B.B.) arbitration our 2001 Alero has been in for repeated repairs of shaking (like dieseling) and stalling problems when the air conditioning is being turned off, as it was designed. August (2002) of last year when we were on vacation in shipshewana, Indiana, this problem became very severe. Along with an oil change light that came on (without reason) at 5,454 miles, bill reset this. The following day our low tire pressure light came on at 5,580 (without reason).

The consumer states that on three seperate occasions they have been left without a vehicle due to the engine throwing coolant out of the coolant resevoir, this results in an engine that was heaving and vibrating/knocking. The vehicle was losing most of its anti-freeze during the operation. On one occasion they found a leaky intake manifold gasket. Consumer states that when he'd take the vehicle to get repairs, the problem was never found or there was an impression that the vehicle was okay. Also, the consumer states that the cooling system is designed in a way that air bubbles cannot be bled out and would like his money back.
