2008 GMC Canyon Problems

Heating & Air Conditioning -- Verified

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

Exhaust & Emissions -- Verified

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Maintenance -- Verified

GM recommends replacing the engine coolant at 100,000 miles; however, our technicians tell us that the coolant may become contaminated and require a complete cooling system flush every 60,000 to 70,000 miles.

Maintenance -- Verified

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.

Drive Train -- Verified

Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.

2008 GMC Canyon Recalls (Recent)

Body, Interior & Misc., November 18, 2010

RepairPal Expert Overview:

General Motors is recalling certain 2004–2011 Chevrolet Colorado, GMC Canyon, and Isuzu regular and extended cab models without a rear seat and equipped with a 60/40 front bench split seat for failing to comply with federal safety standards on child restraint anchorage systems. The top tether anchor for the front center seat is not accessible and the manual provides no instruction on its use. In order to correct the problem, dealers will cut a hole in the back panel trim cover to allow access to the top tether anchor and will provide supplemental instructions on the use of the top tether.

warranty doesn cover any of above problems

Purchased new and to date w/60,000 miles this is a good dependable vehicle, good fuel mileage. The rear brakes squeak occasionally and with the high back rear seats vision is slightly obstructed.

I purchased my new Canyon in Dec. of 08.
Firstly, I am extremely satisfied with the performance, relaibility, and versatility.
It out performs any other truck in its class with great fuel mileage, and tow/haul capacity.
This truck rides nice and handles perfectly.
But it does have its faults.
1. I find that a lot of parts wear or fail too prematurely.
This I find unacceptable.
Things I had to fix or have replaced
Repaired myself - Heater resistor circuit for HVAC fan speed (connector plug was burnt)
Failed and replaced at 2010 inspection year (MVI) - Inner tie rod (front end steering part)
NOTE: If I could have had the option of using MOOG replacement parts, I would have.
All original parts are none servicable (none greasable) that is why they wear out.
Lube Oil and Filter (there is nothing to lube but the door hinges, and they don't even do the tail gate latch - I have to do that myself)
