My rear passenger door opened while I was driving. The car was recalled in 2006 to supposedly fix this problem. We brought it in the spring of 2006 as per the recall. If my 9 year old daughter was not buckled in she would have fallen out of the vehicle. The recall was 05007.

Rear driver side door would not latch. No indication that door was opened. I have filed a complaint (odi 10335683) about the passenger door that I repaired previously. This was the exact issue for recall 05007. The vehicle was brought in spring 2006. Obviously g.m.s "fix" is not working. Luckily this time the vehicle was in my driveway.

The transmission cooling lines corroded which caused the transmission fluid to leak out while on a 20 mile round trip from our house. The truck started to run rough as we pulled in the driveway and there it died. I had it towed to a local transmission repair shop where they confirmed the transmission was dead, rebuild or replace. I paid to tow it to the gm dealership where I bought the truck and they confirmed the tranny was dead. Aluminum cooling lines rotted out, drained the fluid and the unit fried. There are no warning lights or monitoring of this fluid level per gm. This truck had been serviced by this dealership. The service mechanic told me that this is not a common occurrence but this is not rare either. He said gm will not help with the repairs and he was right. I had the local tranney shop do the repairs for 2500.00, less than gm's 4500.00. There have been many problems with this truck, I will do another report regarding the failed door latches, and I gave gm the time to repair their problems and then they tell you to "stuff it" when their bad designs get real costly. Last gm in my driveway.

Three of the four door latching mechanisms had to be replaced in this truck. The doors would look like they closed but they would open as you turned a corner. This occurred twice when I had my kids in the truck, first on the passenger left side then a few months later the passenger right side. I am glad gm didn't screw up the seal belts too. This is dangerous.

The outside back door handles do not work properly. During the warranty period, I brought the car back to the dealership where we purchased it, a few times, and they tried to convince me that the child safety locks were engaged. If the child safety locks were engaged, we would not be able to open the doors from the inside. The problem we had then and continue to have is that the outside back door handles do not work. I used to think of it as a mere nuisance until recently. This is a safety issue. I strap young children, in their car seats, into the back seats of that car. In an emergency, they might not be able to be reached quickly unless my wife or I were there to say that the door handles don't always work and you must open the front doors and reach into the back to the inside door handles to open the doors. Chevrolet has maintained that they work properly. It's kind of ironic, we strap our kids in safety seats to keep them safe, but in an emergency, we might not be able to get to them because the door handles don't work. There is a safety problem here and chevrolet needs to fix it.
