Hopefully they do. I had it in a few weeks ago for a sensor fix as it was not starting on the first turn of the key and that was not covered so we will see. I will call later this week and if not covered i will change it myself. They really are great commuter cars.When i first moved out to the country i bought 2 -01 cavaliers then a 04 cavalier show car and a 04 aveo and now the 09s and these are the first problems i have had with any of them.
