Timing belt broke prematurely at 54541 miles. Gm owners manual says to change it at 60000 miles. Car was worked on by gm under there special bulletin for this problem. However the car had to be returned to the dealer, this time it 56870 miles on it when the ses light came on I took the car to aamaco on Saturday because the dealership was closed some of the codes were my transmission I was told it wasn't going in 4th gear and burned my transmission fluid. So I had my transmission serviced at my expense by the dealership. The dealership told me that gm had the part #'s listed wrong and they had installed the wrong parts when they had worked on the car the first time. So now they put in new parts and the car still doesn't run right. They tell me I need new plugs and wires and that the cost would be 300. 00. I told them no way I was given them 300. 00 for 4 plugs and 4 wires. So they ended up changing the plugs for 32. 00 and I changed the wires myself. At 56987 miles car goes back to dealer third time, ses light on, cause : intake manifold tuning solenoid disconnected and timing belt to tight. At 57012 miles a c/s ses light on, cause; low efficiency the dealer replaced the catalytic converter due to the timing belt. Car has never run right after these attempts of repairs and now sept. 2008 ses light comes on again the has 66200 miles on it. Took it to the dealer and they told me I needed new wires and plugs again and that they could not do anything if I did not let them change them. This is just another case of gm not standing behind there products that fail.
