GMC has a pretty sweet lineup of crossovers. In fact, models like the GMC Terrain and the GMC Acadia are some of the most popular in the segment.

According to that database, these are the most complained about GMC crossover SUVs.

It’s important to note that just because a model receives more complaints than others doesn’t necessarily mean it’s a bad crossover SUV. It often simply means that it’s a popular model with more units out there for consumers to complain about. However, it never hurts to know what others are experiencing in any given car when you are researching the market.

GMC crossover complaints

Again, it’s important to understand these numbers are not represented by percentages. The number of complaints is a sheer number for the given model for the entire time it is in production.

Plus, it’s also worth mentioning that these numbers are the entire number of complaints out of every unit out there. So, just because a model has hundreds of complaints it’s not necessarily an unreliable vehicle. That said, it never hurts to know what people have experienced with certain models when you are shopping for a new or used crossover.
