Motor compression,.
Multi cylinder compression failure.
The cam actuator first failed at 57,000 miles in 2009. It now has failed again at 94,000 miles in March 2013, the cost to repair this is approx $900. 00 each time. I can get milage from my tires at a lower cost. This is an item that should not a normal maintenance item. This truck has been a lemon from day one.
When I slow down my vehicle begins to spudder and sometimes turns off. At first I thought it might be the fuel filter which was changed but problem persists. The vehicle has shut down on the highway when I slowed down for traffic. I place it in neutral while still in motion and turn it on again then immediately put the vehicle in drive to avoid getting hit. I first thought it was just my vehicle until I came on her today and found other people with similar problems.
Engine idle speed. When decelerating to stop, the engine idles so low that it quits and has to be restarted.
Faulty cam actuator solenoid causes loss of power and rough idling. Common to 2005-2006 chevy Colorado/GMC canyons. This fault also releases debris into the engine that causes potential for further damage. Occurred at 70k miles on my vehicle without prior warning and all regularly scheduled maintenance has been performed. Replacement of the solenoid and an oil change is necessary to correct the issue (that gm is aware of since they've redesigned the solenoid since this edition).
Heater fan quit working on 1 2 and 3. But sometimes would come back on, when on 1 2 or 3. And when it was on you could smell plastic burning. And when checked the into it found the plug on the wiring harness that plugged into the resister on the fan was loose and causing the wires to melt. This loose plug was loose from the factory, no way could have got too small over the years. New plug and new resister placed concern if fire results could cause death injuries, garage fire or house fire if vehicle placed in garage at night.
The sales person promissed me a lot of things and now they do not want to fix the truck . I am having a lot of engine problems with this truck and I would like to give it back to the dealer.
