I am driving a 2019 GMC Terrain SLT, and I have a serious concern regarding a recent service experience. On 02/10/2026, I had an oil change and a complete vehicle inspection performed at Kunes GMC Greenfield, Wisconsin. After the service was completed and I returned home, I noticed an unusual noise coming from under the engine hood. I immediately went back to the dealership and informed them of the issue. I was asked to return the following day (02/11) for further inspection. After their investigation, I was informed that the vacuum booster had failed. It appears that this issue was not identified during the original inspection, and I was the one who brought the noise to their attention. From my understanding, vacuum pump/booster issues are common with many 2019 GMC Terrain models. I am surprised that this has not resulted in a recall, especially considering the potential safety risks it poses to me and my family. What concerns me even more is that this issue was not detected during

My family and I were returning home from vacation in another state, and while we were driving on the interstate, an alarm popped up on the DTC stating ruduced engine power. I tried to start slowing down so I could take the next off ramp and could not push the brake pedal in. I had absolutely no brakes trying to slow down from interstate speed. I was able to pull into a gas station parking lot while avoiding other vehicles. I was very lucky not to get in an accident. I had to have it towed to the nearest service center and was charged nearly $4000 for repair. The car has not ran right since we recieved it back. I called them back to let them know and was told the only way I would not have to pay to have it looked at was to bring it back to them. That shop was four and a half hours away from my house. The car was less than twenty miles out of the warranty when it broke down (nine miles to be exact), then they lied on the the paperwork and put the milage after they test drove it.

Vehicle was started for the second time that day on 1/5/26 and the engine light was on. I drove the vehicle to an auto parts store to have them check it with an OBD-II scanner. It had code P050F. I had no idea how serious this issue could be at the time. I made an appt with the GMC dealership and dropped it off the evening of 1/6/26. They said there was a software anomaly in the engine control module and needed to be reprogrammed. I paid the $200 diagnostic fee for them to reprogram it. I learned that this anomaly could have caused my brakes to not work while driving it. I had been driving the vehicle back and forth to work until I dropped it off. This issue could have caused serious harm or death to myself and others. While researching online, I've seen that other vehicles have had safety recalls and additional warranties added for these issues, but my vehicle isn't included in this.

Failure of the cam driven vacuum pump causing brake failure. Leading to a hard brake pedal which increases risk of a crash. Debris from the broken vacuum pump can fall down into the engine causing a catastrophic failure of the engine needing a replacement. This happens with little to no warning. Warranty companies will not pay to repair the known issue. A recall needs to be issued for this to provide a fix. This is a family suv and I do not feel safe putting my children in a vehicle that can endanger their lives and safety.

I bought this Terrain brand new from Betten Baker Chevrolet in Muskegon Mi in 2019 with 500 miles. That same year we had transmission Slippage causing it to slip out of gear then slam back into gear while driving. I took it to the dealer to have it looked at. They did nothing and informed me it was known by the manufacturer that this was an issue. I then had to bring it back for electrical issues as the lights would all start going off in the cab including dome lights and shift buttons. All key fob would not be recognized by the car and would have to be reprogrammed counting 5 times now. Now I am sitting at just oflver 100,000 miles and what I thought was going to be a simple spark plug change gas turned into a complete motor failure. did an oil change and there was no oil in it. The turbo was replaced and now the engine started making a lot of rattling noises and just stopped. the dash says service transmission, ECS, Extremely low battery voltage and has jost die after oil started pou

Vehicle has had check engine light and engine reduced power flicking on and off for months, randomly reducing power on highway or nearly causing accidents. Brought car to GMC dealer, they said it was underboost code and needed new turbo. Paid over 7,000$ for repair. Next morning, same issue still was happening. I believe my vehicle has EMISSIONS recall issue “N192271200 Charge Air Cooler Disconnect at Throttle Body” but GM has not properly attached my vin number for this recall repair. I have poured thousands into repairs out of pocket and the same issue still persists. I believe strongly the recall emission issue is the problem and should be on my vin. Vehicle has been to dealer 3 times in the past 2 weeks, issue has not been fixed. Improperly diagnosed, random repairs made not fixing actual issue.

When approaching a stop sign, the brake pedal became extremely hard I was unable to stop, and rolled through the intersection avoiding collision. I was able to slow down enough to engage the emergency brake. There are no lights on the dash.

I was driving home from vacation the vehicle went into limp mode and started to run very poorly with a brake pedal that was almost impossible to push. I limped the vehicle a couple of miles to the next exit. I had the car trailered home and taken to a service center the following Monday. They inspected the vehicle and found the vacuum pump had failed and caused what was described as “catastrophic engine failure.” They are now saying it needs a full motor replacement due to the widespread and severe damage. This is not the first time this pump has been an issue or supposed issue. About a year before this incident a month after we bought the vehicle in used condition from a GM dealership it started making a noise. We took it back to see if they could help us out being that it was recently purchased and they diagnosed it as the vacuum pump making the noise. They wanted almost $800.00 to replace it. I googled a video on how to fix it and found the cost of the part. The part itself is b

The contact owns a 2019 GMC Terrain. The contact stated that while driving at an undisclosed speed, the vehicle hesitated, with the check engine warning light illuminated. The contact stated that the warning light turned off after approximately three miles of driving. The contact also stated that the vehicle experienced abnormal RPM fluctuations while driving. The vehicle was taken to an independent mechanic, where it was diagnosed; however, the diagnostic information was not provided to the contact. The vehicle was not repaired. The vehicle was then taken to the dealer but was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 117,951.

Mileage: 117,951
