First, the struts came off, then the piece holding the air filter broke away, now the pulley has exploded and has destroyed the timing belt and serpentine belt. This car is junk made with cheap parts. Not good for someone with children.

My complaint involves a replacement timing belt manufactured by General Motors detroit and purchased on my behalf from the parts department of steve rayman Chevrolet on March 29, 2010 by ken black of fairground auto and body shop for installation on my 2004 Chevrolet Aveo. The replacement of the timing belt was routine maintenance and was intended to protect my auto from damage that might occur when a timing belt fails. At that time my car mileage was 69631. On October 1, 2010, this replacement timing belt failed after only 4327 miles and 6 months of service. A section of the teeth which engaged the timing belt separated from the body of the belt. The defective belt flew into my engine causing extensive damage. I had the vehicle towed to fairground auto where this damage was repaired at a cost to me of $2098.30. Mr. Ken black advised me that since the belt was defective he believed that General Motors should reimburse me for the repair. He took the belt back to steve rayman Chevrolet where he showed it to the parts manager mike stewart who concurred that the belt definitely had a manufacturing defect and made attempts to get GM in detroit to stand behind the part and take care of my damages. GM refused to do anything. These details can be verified with ken black of fairground auto at 770 429 8473 as well as mike stewart, parts manager at steve rayman Chevrolet, at 770 953 0100 ext 3047.

While on my way home, I noticed that my vehicle started smoking from the hood and without warning the "check" dash lights came on. I noticed that my car started slowing down and I coasted it to the side of the road. At this point my vehicle cut off and wouldn't start. Once, my vehicle was transported home, I had my mechanic to come out and inspect my vehicle. My mechanic looked under my hood and saw that my vehicle had lost alot of antifreeze/coolant. He looked to see what cause this and realized that the thermostat housing unit had busted-actually it was split in half. My mechanic also stated that the busted thermostat housing had caused the leakage of the antifreeze/coolant. My mechanic informed me that the thermostat housing had to be replaced. After having the thermostat housing replaced, my mechanic tried to start the car, but it wouldn't turn over. I had my vehicle jumped, and even the battery inspected but it wouldn't start. In addition, the starter, timing belt were inspected as well and were in good condition. Please be advised that I only have 53,000 miles on my vehicle. My mechanic did a thorough check of my vehicle and realized that some water had leaked into my oil and that antifreeze/coolant had spilled into an engine valve. From my own research, I've found that Chevy has had numerous problems from the 2004 Chevy Aveos-thermostat housing units from other customers. In addition, originally the thermostat housing was plastic, but Chevy changed it to an aluminum one because the "plastic thermostat housing" that originally came with the vehicle was extremely faulty. It is very dishonest and a shame that GM/Chevy never notified me that I needed to bring my 2004 Chevy Aveo in to get the plastic thermostat housing replaced with the new aluminum one. I bought this vehicle brand new in 2005. It was Chevy's responsibility to notify me of this situation. Also, from what I've gathered, the plastic thermostat housing was unsafe.

Four days ago I received a letter regarding service that was required to be performed under the extended warranty agreement I purchased with my car. The service needed was on the timing belt. On Sunday, two days after receiving the letter the timing belt broke on my car, causing further damage to the engine. My extended warranty ended at 60,700 miles and I currently have 67,000 miles on the car. The letter was too late in arriving for me to prevent this damage being done, as it seems that the timing belt was supposed to be replaced at 60,000 miles. The car is currently at the dealer with the engine having been sent to a "specialist" for further work.
