The 2022 GMC Terrain is meant to be a luxury-minded SUV, allowing for family travel in style. The automaker points out the “head-turning details” in an effort to get customers more excited. In the meantime, the missing electrical system, malfunctioning powertrain and shoddy structure are all overlooked.

Problems with the Electrical System

There haven’t been a ton of electrical system complaints yet because the company had to ship out massive amounts of vehicles without the latest technology.

Here’s what one customer wrote on the Terrain Forum. “What I am NOT happy about is that after Nov. 15, 2021 build date, it won’t have heated front seats. On the Chevy Canada website it shows they deduct $50 for lack of heated seats. Heck, most every car has heated seats and my sciatic needs this. Dealer says they can get aftermarket heat installed for $650. But I just found articles that GM is now saying they can retrofit the chips to the cars missing the function as early as mid-2022.”

Not only are drivers unable to get the technologies that matter the most, but there’s a lot of question as to how any of it will work once it is retrofitted. Looking back on previous models, it’s clear that GMC struggles to incorporate reliable technology. In fact, it wasn’t that long ago that the automaker dealt with class-action lawsuits because of defective infotainment systems that were maxing out the volume on the radio without any manual input. It looks like this was one of the “head-turning details” that was completely missed.

Problems with the Powertrain

There have also been a lot of complaints about the 9-speed transmission. While customers were happy to hear that the CVT wasn’t being added, there’s still a call for something more reliable.

One comment on the Terrain Forum mentioned, “I do not like the 9 speed in my Traverse. Too much shifting. The 6 speeds in the rest of my fleet are just fine. IMO excessive shifting is excessive wear no matter how intensive your maintenance is. I do not seeing it going 200k miles like 6 speed trans.”

The company knows that there are already problems with the mechanics on the Terrain. Service Bulletin #PIP5651E states that the charge air cooler pipe can become disconnected from the SUV’s throttle body, thereby causing reduced power and several diagnostic trouble codes. With broken parts, it becomes difficult to navigate any “terrain.”

Problems with the Vehicle Structure

Looking at the structure of the GMC Terrain, it’s clear that the engineers took virtually no time to perfect the design.

One final comment on the Terrain Forum talks frankly about the sunroofs saying, “Most have had bad experiences with them previously and wouldn’t recommend them.”

This GMC SUV barely made it to the dealerships before it suffered a massive recall. NHTSA Campaign Number 21V612000 says that affected models have Hankook tires that were manufactured incorrectly, leading to tread separation. If the tread were to separate, a crash could become imminent. At this point, maybe GMC hopes that a bunch of Terrain models will crash and burn before people realize how defective they actually are.
