New GMC brand vehicles ranked well below average in the J.D. Power 2023 Mexico Vehicle Dependability Study, which measures problems per 100 vehicles (PP100) with a lower score being better.
According to the results of J.D. Power analysis, respondents reported 225 problems per 100 GMC vehicles, while the segment average for Premium vehicles is a PP100 score of 154, or 71 less problems per hundred than encountered with Big Red.
The Premium segment – GMC is considered a premium brand in Mexico – was won by Mercedes-Benz with a PP100 score of 136, close to a hundred less problems than the GM brand. Audi took second place with 147 problems. Below the 154 average, BMW came in ahead of GMC as well with 163 PP100.
GMC also ranked below average in the same study last year, though in 2022 it actually outperformed 2023’s winner, Mercedes-Benz. However, the brand’s 2023 score of 225 PP100 is somewhat improved from last year, when it had 243 problems per hundred units. The improvement could simply be statistical noise or it could be a positive change in vehicle quality.
Infotainment was the area where people complained most about problems with their vehicles across all brands. Millennial and Gen Z vehicle owners had the largest numbers of complaints about infotainment systems, with senior regional J.D. Power director Gerardo Gomez pointing out these generations have “grown up in the digital age and their expectations are higher when it comes to infotainment operating correctly.”
Software updates from the automaker tended to improve owner opinions about the infotainment system as well. The system was rated as “much better than expected” by about a third of respondents if an infotainment update had been installed in their vehicle after purchase. Overall, Boomers were most satisfied with infotainment systems, while all drivers found few problems with driver assistance technology.
The study queried 6,440 vehicle owners about their experiences to reach its conclusions. It asked respondents to rate their vehicles, 2021 or 2022 models recently purchased, on nine areas, including “exterior; driving experience; features/controls/displays (FCD); driving assistance; infotainment; seats; climate; interior; and powertrain.”
