On my daughters 2004 Chevy Aveo I had the timing belt, water pump, and T'belt tensioner replaced at 59826 miles, per manufactures recommendation. About 20000 miles later the idler pulley broke, destroyed engine. GM has not recommended replacing this part per their maintenance schedule, why not?

5 months ago, we replaced our 2004 Chevy Aveo's engine due to timing belt failure and had a new one put in. Today (2 weeks after) our car broke down again due to timing belt failure we are finding out we are needing to replace the engine again!

The timing belt on my 2004 Chevy Aveo broke at 55,000 miles. GM recommends that the timing belt on Aveos be replaced at 60,000 miles. There have been numerous reports of Aveo timing belts breaking between 50,000 to 56,000 miles; however, GM has not posted a warning on their website, nor have dealerships been informed. A closer inspection of my car revealed that the idler pulley, which is made of plastic, melted and molded itself to the engine block, which is what caused the belt to break.

Aveo

  • 53,000 miles
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.

I am driving my 2004 Chevy Aveo at 35 miles an hour, all of a sudden it died. I have 54,000 miles on it. I had it towed to a mechanic and they said that the timing belt broke and now I need to replace the engine. In my manual it says that timing belts need to be checked at 60,000 miles. I was told by GM that even the that is the case I am out of my warranty so tough luck. I have found about 300 complaints about the same thing happening while searching online. I don't know if there is anything you can do about this but I am trying anything I can to get my car fixed.

Aveo 4-cyl

  • Automatic transmission
  • 70,000 miles
Timing belt failed at 70,000 miles causing severe engine damage. Timing belt failure is apparently an issue with the Aveo as GM issued a service bulletin on this in Oct 2006. Based on internet search of Aveo problems, Chevy is having problems with the Aveo's timing belt failing even before the recommended service date.
