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.

Aveo 4-cyl

  • 39,600 miles


I am disabled, and in 2005, I purchased a new Chevy Aveo from GM dealer and in 2006 GM sent notice to all dealers that these engines had a defective timing belt and to notify and offer new car buyers a free replacement of the defective part as failure of defective part would likely destroy the engine. I received no notice from GM or my dealer. When my car reached just 49K miles the defective part failed (rubber timing belt) and has caused massive engine damage requiring all new head, valves, and other parts. Dealer refused to even diagnosis the vehicle to avoid documentation of cause and liability and I had at attempt myself and was severely injured. I live on key West and only dealer who sold me the vehicle is miles sales and service. I have spent $600 to replace defective timing belt and associated parts but one cylinder has no compression confirming values were bent and a 1.5K head replacement is needed which I cannot afford living solely on social security disability in section 8 public housings so now being disabled I have no transportation for medical appointments, or even food shopping. I was victim survivor of 9/11 wtc attack and since GM and dealer knew of this defect and failed to give notice I believe they are in violation of several consumer and regulatory requirements about known defects notice and replacement standards and have put buyers of their product who are disabled.... in physical danger.

The contact owns a 2005 Chevrolet Aveo. The contact was attempting to accelerate 15 mph from a traffic stop when the vehicle exhibited an unusually loud grumbling noise before stalling. The contact was able to restart the vehicle. The vehicle then exhibited the same noise before stalling a second time. The vehicle was towed to the contact's residence. The vehicle was inspected by an independent mechanic who advised that the retensioner belt was fractured and spew shards of metal throughout the engine area. The dealer advised bringing the vehicle in for diagnostic testing. The vehicle was not repaired. The failure and current mileage was 64,276.

Car type: 2005 Chevy Aveo problems I have had with this car; 1. oxygen sensor needed replacement by 41, xxx miles 2. at 82, xxx mi. Wiring problems in fuse box wires came loose (possibly a fire hazard) burnt the wiring harness. (char marks on the wiring harness) caused the interior (instrument cluster panel) and exterior lights (daytime running lights)(yellow lowbeams that control turn signal) to turn off while driving the vehicle during the night time. Fix cost me $125 plus tax 8.25% this isn't the first time I've heard of this happening in fact its on many online forums as happening to several other people. 3. at 92, xxx miles. Thermostat housing cracked in the center where the thermostat is located at (thermostat housing is plastic) very cheaply made. No parts houses carry this item. Its a GM part. Got stranded 44 miles from home and had to get a tow truck to bring car home. Cost; $115 + tax corrections made to vehicle; 1. purchased a new oxygen sensor for about $120 2. taken electrical problem to a shop and had the shop fix it for $125 +tax 3. problem still pending. Parts not available at part houses I.e. autozone O'reileys A-line, advanced auto, etc....I believe parts houses do not wish to carry these parts. Part is too cheaply made for them to carry I believe the part should have been made out of metal.(steel, aluminum. Etc....) property damage: Damage to wiring harness in vehicle Chevy Aveo fire: Burnt wiring harness in vehicle, wires had to be soldered from a separate locality in engine compartment.

Plastic elbow on 2005 Chevy Aveo, due to heat, broke, causing engine to overheat, had to have engine head resurfaced in March 2009; then catalytic converter went out. After fixing igniter, test proved, engine was only firing at less then 50% on cylinders 1 & 2 due to lack of compression, that began with plastic elbow breaking.

2005 Chevy Aveo with 12,000 miles. For the past two days, when I let up on the throttle gently, the car does not slow down, exactly like complaint # 10262822 described. The pedal feels as though the linkage is sticking somewhere. If I "hit" the throttle hard and immediately release, the throttle returns to idle position.

The contact owns a 2005 Chevrolet Aveo. While merging onto the highway at an unknown speed, the vehicle shut off. It took approximately five minutes for the vehicle to restart and then it shut off again. There were no warnings prior to the failures. The vehicle was taken to the dealer twice, but they could not diagnose the cause of the failure. During the third visit, the check engine light illuminated and the dealer stated that the oxygen senor was activated and would not cause the vehicle to shut off. The manufacturer advised the contact to take the vehicle back to the dealer. The failure mileage was 12,000 and current mileage was 39,000.

I own a 2005 Chevy Aveo. Have owned since 7-15-05. No problems except for head gasket replaced while still under warranty. On 3/23/09, I was on the way to work & went to pass a car. As I pulled back in to the lane & took my foot off the gas the cars speed still increased. Applied brakes and could still feel the engine pulling as if I were still pressing the gas pedal. Slid in to neutral and the rpms raced to 7. I flipped back in to drive & the car kept speeding up. Put back in to neutral & hit the gas a couple of times to try & kick it down & it finally went after the 3rd time flipping it back & forth between neutral & drive. Side note: Car was sitting out all night in with temp dropping to teens with windchill. This is the second incident. However, the first time it was not this extreme. I was at approx 80-85 mph before it kicked back down this time.
