GMC Reliability for the Year Ending June 30, 2018

General NotesHow do we select "competing car models"? Users of TrueDelta's car price comparison tool most often compare these cars to the GMC.

Models and statistics marked with an asterisk (*) have very low sample sizes. These results, visible only to logged-in members, provide only a rough estimate of car reliability.

Any result under 5 repair trips per 100 cars is likely a result of the small sample size, and should be expected to increase in future updates.

New models often start out with high repair rates, and then improve as the manufacturer identifies and addresses common problems. MethodologyOnly successfully completed repairs are currently included in the analysis. Routine maintenance, most wear items, recalls, and problems fixed with just a reflash or warning light reset are not included.

An asterisk (*) marks results based on small sample sizes.

GMC Reliability

You won't find GMC reliability information like this anywhere else. Actual repair frequencies, not just vague dots. So you can tell how much the GMC truly differs from competing car models in reliability.

These stats are promptly updated four times a year, to much more closely track GMC reliability as the cars age. Others tell you how reliable the GMC was a year ago, when the cars were a year younger and had 12,000 fewer miles on them. Only TrueDelta tells you how reliable the GMC has been recently.

GMC Reliability and Durability: Pros
YearBody/PowertrainComment
2011 4dr SUV turbocharged 228hp 2.0L I4
9-speed shiftable automatic FWD		 Seats 8 people. I test drove a leather with DVD used vehicle prior to purchasing and it was decent. I purchased this in March 2011 with 5500 miles from Bob Moore in OKC. Seats were a little uncomfortable but not unbearable. at 30000 miles the rear strut had issues on the liftgate, noisy (really noisy at low speeds) power steering, tires wearing out, and gas tank showed half full when I ran out of gas. Today I found out there is a leak in the discharge hose of the Ac and possibly more issues because I have no ac at 90,800 miles. Seats are garbage, gas mileage never averaged over 21, wont tow much of a load, and small inside. I would never recommend a GMC, anything from Bob Moore or the Acadia. I have owned over 50 vehicles and this is the most problems for a new vehicle I have ever had. see full GMC review

2002 4dr SUV 355-horsepower 5.3L V8
6-speed shiftable automatic 4WD w/low range		 Reliability has been a mixed bag. It came from the factory with a radiator that leaked into the tranny-oil cooler. GM fixed that under warranty. The computer in the radio died, which drained the battery. The replacement was DOA. Now I have an aftermarket head unit. A couple of little items (the washer bottles, for example) have broken, but I have never worried about the powertrain or the soundness of the body or chassis; and the interior and exterior have held up very well. see full GMC review
2001 4dr SUV 420-horsepower 6.2L V8
6-speed shiftable automatic 4WD w/low range		 11 years 187,000 miles and the only thing I have ever had to change besides regular wear/maintenance itemswas a water pump, rear a/c evaporator, 2 window regulators.Extremely comfortable, luxurious,great styling and extremely economical.Power and operationis strong as always. see full GMC review
