General Motors has positioned the new GMC Terrain as a premium alternative to its corporate cousin, the Chevrolet Equinox. But we don't think it's worth the extra cost. We found the Terrain lacking in some key areas, such as ride comfort, handling agility, outward visibility, ergonomics, and noise isolation. In fact, the less-expensive Equinox is a more capable and appealing vehicle.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2018 GMC Terrain owners. The owner comments describe problems respondents experienced with this vehicle.

In-car Electronics

CD or DVD players, radio, speakers, GPS, communication system (e.g., OnStar), display screen freezes or goes blank, phone pairing (e.g. Bluetooth), voice control commands, steering wheel controls, portable music device interface (e.g., iPod/MP3 player), backup or other camera/sensors.

What Owners Say

Android Auto

"Not user friendly. Unable to listen to text messages. Ford SYNC was easier to operate. Android Auto instructions are not clear or do not apply to this vehicle."

Stephen R., CO (2018 GMC Terrain SLT 2.0-L 4 Cyl turbo)
Display screen goes blank

"This issue was covered and fixed via a recall about a month ago. That kind of a defect should never happen."

Anonymous, FL (2018 GMC Terrain SLT 1.5-L 4 Cyl turbo)

"The infotainment screen has, on multiple occasions, completely locked up on me. In this car that means you can't even change the radio station since it all goes through the unit. Thankfully the HVAC system does not. I haven't gotten it fixed yet, but I intend to bring it up at my next service. Because it is intermittent, I am concerned it will be almost impossible to isolate and fix."

Anonymous, CA (2018 GMC Terrain SLT 2.0-L 4 Cyl turbo)

"Screen went blank and had to have a software update/recall to fix it."

Jamie W., OH (2018 GMC Terrain SLT 1.5-L 4 Cyl turbo)
External music device interface (e.g., smart phone, MP3 player)

"When using a usb thumb drive and I start the vehicle I will often get the message that no device is found, even though it is plugged in. I must turn off the engine and open the door to shut the vehicle down completely and then restart the vehicle and usually the device is found and will play. If I switch from the USB device to radio and back again. It might also indicate there is no device found. It's annoying when driving at highway speeds because I must stop the vehicle to shut it down and restart it to have it find the USB device. Usually won't do that and just continue to listen to the radio."

Dennis F., KS (2018 GMC Terrain SLT 1.5-L 4 Cyl turbo)

"Sometimes the music would not play. Often if would start if I would stop the vehicle and start it again."

Anonymous, MI (2018 GMC Terrain Denali 2.0-L 4 Cyl turbo)

"Randomly (about once every 4 starts) the the usb stick loaded with music I had inserted would disappear - that is I would receive a message No Device Connected. A car restart made this message go away."

Ted J., BC (2018 GMC Terrain Denali 2.0-L 4 Cyl turbo)

"Doesn't always detect the thumb drive."

Larry F., NY (2018 GMC Terrain SL 2.0-L 4 Cyl turbo)
In-dash navigation system (GPS)

"They were updated"

David L., OH (2018 GMC Terrain SLT 2.0-L 4 Cyl turbo)

"The navigation stopped functioning, and the Dealer had to order a new micro-processor (chip) from General Motors in Detroit. The replacement had several added features so it was likely a 2019 model; e.g., it had added warning alerts if schools were in the area."

Michael M., ON (2018 GMC Terrain SLT 2.0-L 4 Cyl turbo)

"The antenna was not working properly and could not locate the vehicle. The antenna was replaced and the problem was resolved."

Fred H., NY (2018 GMC Terrain Denali 2.0-L 4 Cyl turbo)

"All segments of the infotainment system are integrated. OnStar System failed and I had to replace the entire unit to resolve. Settings lost / subscriptions needed to be transferred / Customer Care reps unfamiliar with the NEW VERSION of OnStar radio - System. Customer care located in many locations including overseas"

Henry F., NY (2018 GMC Terrain SLE 2.0-L 4 Cyl turbo)
Phone pairing (e.g., Bluetooth)

"1. I leased a 2018 GMC Terrain on 2/21/2018 from Thorson Buick/GMC in Pasadena and on that day, the dealer did not try to pair my cellphone or demonstrate that two systems were compatible. Instead the sales rep showed me how her apple iphone worked with the car. The dealer did not provide me a list of cellphones which are compatible or incompatible with the GM bluetooth radio and they certainly did not suggest that pairing might be a problem with certain cellphones. 2. I spent over a week trying to remedy this problem (calling the GM radio division, going to my cellphone dealer (T mobile), going to another GMC dealership (Reynolds), calling the cellphone maker and testing my cellphone with other vehicles in order to try to understand the root cause of the problem. I had no difficulty in pairing my cellphone with my Toyota Sienna 3. Finally, I went to Thorson Buick/GMC on March 7th. They attempted and were unable to get the vehicle bluetooth to pair with my phone. The service manager said he contacted GM and they told him that my phone (an LG Stylo 3+ which is less than 6 months old) was not compatible with the 2018 GMC terrain. He further explained that 'I am not the first and will not be the last person with this problem and that GM can't possibly design their bluetooth systems to be compatible with every cellphone'. He said that he would call GM and see if they were willing to do anything to make any accommodation in this matter. Eventually GM was willing to pay me one lease payment as a sign of goodwill. However I had to buy a new cellphone which was on their list of compatible phones and this cost about 3 times my monthly lease payment."

William S., CA (2018 GMC Terrain SLE 1.5-L 4 Cyl turbo)
Radio

"Periodically Radio will not turn on following engine start-up"

Stephen R., CO (2018 GMC Terrain SLT 2.0-L 4 Cyl turbo)

"Randomly the radio display would only show the station, none of the other information. Using the steering wheel controls would not change the station, only touching the screen worked. The light indicating which preset you were listening to would not be on. If you changed stations using the SW controls, the lights came on and moved, but the station didn't change. Turned the radio on and off did not help. The car had to be turned off, then back on and then the radio would work normally. Reception was also always very poor on FM."

Ted J., BC (2018 GMC Terrain Denali 2.0-L 4 Cyl turbo)

"Display would not show information, would not change stations except by touching the screen. Clock would lose 5 minutes a month, Steering wheel controls sometimes inoperative."

Ted J., BC (2018 GMC Terrain Denali 2.0-L 4 Cyl turbo)

"Periodically the radio info appears on the screen without any sound."

Stephen R., CO (2018 GMC Terrain SLT 2.0-L 4 Cyl turbo)
Routine software updates

"froze system software update solved"

Anonymous, BC (2018 GMC Terrain SLT 1.6-L 4 Cyl diesel)
Software update fixes

"Take in to shop for repaires."

David L., OH (2018 GMC Terrain SLT 2.0-L 4 Cyl turbo)

"Automobile did not have SiriusXM radio installed as in previous vehicles which caused us to stream through our IPhone. Multiple problems with software, updates, reception, loss of service, etc. Did not realize upon lease that this feature was not available on this model. A real problem"

Ronald M., NY (2018 GMC Terrain SLT 2.0-L 4 Cyl turbo)

"Clock kept gaining time. When taken to the dealer they said they had a fix for it. Also a recall we were unaware of."

L S., NY (2018 GMC Terrain Denali 2.0-L 4 Cyl turbo)

"Will not shift out a low gear. It's like driving in second gear."

Larry F., NY (2018 GMC Terrain SL 2.0-L 4 Cyl turbo)

"This repair was as a result of a GM Recall."

Steven A., NC (2018 GMC Terrain SLE 1.5-L 4 Cyl turbo)

Body Integrity

Squeaks, rattles, wind noises, loose or cracked seals and/or weather-stripping, air and water leaks.

What Owners Say

Squeaks or rattles

"The 2018 Terrain developed an issue with a rattling noise at highway speeds. After several trips to the dealership the issue was fond to be a loose exhaust shield. So far the part has been on order for 2 weeks. I will say that GM has went out of the way to make sure that the issue is resolved."

David M., MO (2018 GMC Terrain SLE 1.5-L 4 Cyl turbo)
Wind noise

"I have had the car in several times for wind noise in the cabin at less than 60 MPH. There is a noise coming from the windshield that they cannot find. I even rode with the Mechanic to see if we could hear it. On that ride along we did not hear the wind noise. That was 6 months ago and since then the noise is back. I am sure it was a manufacturing flaw and it is an intermittent problem. And that is why, I will not lease another GMC vehicle."

Anonymous, FL (2018 GMC Terrain SLT 1.5-L 4 Cyl turbo)

"This is the first turbo we've owned. Extremely noisy while getting underway. I rode in the back recently and road noise was really bad."
