Two Most Common Gripes with the GMC Canyon
The GMC Canyon was a truck that was well-received by an American market that had long been enamored by these powerful and practical machines. That's saying a lot, too. Considering how heavily saturated the market is with so many different pickup trucks from so many different brands, it's very difficult for one or the other to truly stand out-yet stand out the Canyon did. Up until the present day, sales of the GMC Canyon remain impressive. It's difficult to fault the truck anything-its service record is sterling, and the truck is very reliable. No truck is ever perfect however and-however rare they are-these are the problems you have to keep an eye out for if you're driving a GMC Canyon:
High engine idling
This very odd problem was observed with the 2011 edition of the GMC Canyon. Owners have noted that the idling RPM of their engines shot up to around 775 rpm. This meant that their trucks, on their own, start climbing uphill at 5 mph with their feet off the accelerator pedal. The engine in question is the 2.9-liter, 4-cylinder LLVI4. While the problem hasn't caused any untoward incidents to occur, it has caused a drop in fuel efficiency due to the engine consuming more fuel faster.
Due to the rarity of the problem, not only is there no recall order issued out, but many dealerships have no clue as to what causes the problem and how to deal with it. Many have suggested having the engine overhauled by an independent, licensed party. This is costly but does solve the problem easily.
Persistent ABS warning light
Far more common than the preceding problem, and a fixture on the 2005 edition of the GMC Canyon, this problem is also far less dangerous-but is a terrible hassle. Simply put, owners have observed that the ABS warning light inexplicably engages even when there is no clear reason for it to do so. Additionally, though the light is engaged, the system itself is inactive.
Two recall orders were issued with specific regard to the switch that engages the mechanism for the warning light. If you're not covered by the recall-or if you want to be extra careful-it helps to also check the wiring of the warning light to be sure.
