I own a 2004 Chevrolet Aveo and have numerous service issues with my car. Within the first month of ownership, the computer told the transmission to engage upon startup. The dealership replaced the computer module. I then took the car back again due to a grinding noise upon braking. The rear drums had to be replaced due to factory defect. After that I have taken this car back to the dealership eight times for miscellaneous noises, etc.
Today I took my son to school and on the way home I went to do a U turn and my power steering on my car stopped working. Then the check engine light, the oil light, & the battery light lit up and the car stopped running while I was in traffic. Luckily a good samaritan helped me push the car into a convenience store parking lot.
A mechanic checked the battery in the parking lot and said it was fine. He believes that either it is the starter module, the solenoid, or the computer gone bad again. To say the least I would love to trade my little lemon colored Aveo in, but I owe too much and am too upside down to be able to get out from under this troublesome little car.
So now my car sits outside of the mechanics shop waiting for diagnosis. Whether I contact an attorney to go lemon is yet to be told. I would never purchase another one of these again.
It sounds like the 2004 models had teething problems, which of course is no excuse.
My 2005 SVM (base model) has been perfectly reliable, although I won't state it is ultimately reliable until I've had it for five years or so. My friend's 2006 Aveo SVM has had similar reliability.
It also sounds like the more features you add to an Aveo (automatic, sunroof, power windows) the more problems it will encounter. Again, no excuse, but the base models seem to have less problems.
To the above poster: Uh, no, the '04's 4-cylinder does NOT have the power of a V-6. These are great little economy cars, but let's not get carried away.
