This is an intermittent issue and has been occurring at different times since purchase in 1999. While driving engine stalls and I lose power steering control. Experiencing long cranks before engine will start. However, engine eventually restarts but engine stalls again several times before car will run without incident for a brief period. Have had numerous repairs done on this car regarding this issue such as ignition module. Had repairs done in October 2013 where crank shaft position sensor, mass air flow sensor, cylinder and key were replaced. In April 2014 began experiencing same issue again.

: the contact stated the vehicle was overheating and the warning light indicating the coolant needed to be replaced was illuminated. The coolant was replaced, but the problem continued. An independent repair shop determined there was a leak into upper plenum and upper manifold. The gaskets were replaced and the manifold was cleaned. The problem returned a year later, the mechanic determined the same problem occurred. The same repairs were made as well as valves and adapters were replaced. The problem returned and the vehicle was taken to the same repair shop.

Plastic radior tank cracks. This seems to be an issue with GM vehicles in general. I have talked with several people that have experienced the same problem. Crack seems to start at mounting bolt for radior. I have always owned GM vehicles and currently own 3 however, at the cost of $400+ to replace my plastic radior, I may have to reconsider my future purchases.

I was told that the intake manifold failed as well as the lower intake(plenum). (3.8L V6) the work was performed by a Firestone retail store in myrtle beach, SC. Has anyone else had this problem and what were the repair costs? I sure am curious. As far as paint, I had the car painted for $1000.

While driving the serpentine belts broke, causing the vehicle to run very hot. The temperature gauge went up to 270 degrees. Owner will be contacting the manufacturer.
