2005 Chevrolet Uplander Engine cooling Problems

“The check engine light came on and driveability was affected; reduced acceleration and reduced gas mileage, code 0404. Our technician found that the electrical contacts in the EGR valve had failed. Since GM does not produce the replacement parts for this model, a newer EGR valve, harness and computer reprogramming was necessary. The GM dealer and chevy customer service refused to help under our warranty coverage since we were out of the emissions time limit. …”

“It is difficult to pinpoint the first occurrence. Approximately 1 year ago, my wife mentioned that her 2005 Uplander would stall at random times while she was driving.

“The contacted stated the vehicle makes noise and vibrates excessively when pressing the accelerator pedal or turning the steering wheel to the left and right. Vehicle speed does not affect the sound or vibration. The vehicle was taken to the local dealer several times for inspection. The local dealer never diagnosed the problem.
