2005 Chevrolet Colorado Owner Comments

problem #6

Jan 162008

Colorado 4WD 5-cyl

  • Automatic transmission
  • 57,000 miles


The contact owns a 2005 Chevrolet Colorado. While driving approximately 35 mph, the contact smelled a strong burning odor and heard a loud rattling noise. The check engine light illuminated on the instrument control panel. The dealer stated that the bolts that hold the oil lubrication for the 4 wheel drive were too large, which caused the fluid to leak. As a result, the four wheel drive no longer works. The vehicle has not been repaired. The contact has copies of all written correspondence, outlining the cause of the failure. She also notified her state attorney's general office and the manufacturer. The failure and current mileages were 57,000.

- while driving the 2005 Chevrolet Colorado at 40 mph the passenger, looking for the vent, must have accidentally pushed the 4 wheel drive button. The same day, while backing into driveway, the tires squeaked. The contact was unhappy with the design of the vehicle. He believes it is too easy to engage the 4 wheel drive function inadvertently. This vehicle has part time 4 wheel drive. Updated 2/22/2007 -

Colorado 4WD 5-cyl

  • Automatic transmission
  • 4,200 miles


During normal driving my truck will shift into 4WD-high. I cannot determine if it occurs at highway speeds or low speeds (<30 mph), I only notice it when I go to turn. The occurance is intermitten since I bought the truck new in September 2005. It has almost cause me to have a head-on collision with an oncoming car and a building because the turning radius is affected when it shifts into 4 wd. Since the truck has push butten control to change to 4 wd, for several months I thought I bumped or pushed the button by accident, but that is not the case. I have been to the dealer 4 times, the 4WD control head has been changed (fault indicated), transfer case control module has been changed (internal fault indicated), all electical wire harnesses to the transfer case module-control head were checked for shorts. Problem not identified or solved and GM service told dealer to quit trying different things since the problem could not be identified. The vehicial is still under new car warrantry. In another drive train issue that may or may not be related to the automatic shifting into 4WD is a complete rebuild of the automatic transmission at 4200 miles. The transmission had to be rebuilt because no new transmission was available in N. Dakota. I have had no other problems with this truck.

Truck has push button 4WD controls. Three times it has switched to 4WD from 2wd I was at slow speed once in reverse and each time I was turning the steering wheel to the right. Had the truck into the dealer for a defective power steering pump and reported that to the dealer, they said they could not duplicate the situation.

The consumer stated the vehicle has push buttons to change to 4-wheel drive. Without warning the vehicle changed from 2-wheel drive to 4-wheel drive without touching the controls. The dealer changed the computer and said they could not find the cause of the problem. Caller said loaner vehicle did the same thing. Manufacturer said they could not find the cause of the problem either. Had vehicle 7 times at dealer for this problem. The air condition was not cooling properly, therefore the dealer replaced the ac condenser.
