2019 GMC Terrain

The contact owns a 2019 GMC Terrain. The contact stated that while driving at approximately 75 MPH, the panoramic glass sunroof shattered, causing shards of glass to enter the cabin of the vehicle. The contact stated that the panoramic sunroof was in the closed position when the failure occurred. During the failure, the front passenger sustained lacerations to the back, leg, and shoulder. The eleven-month-old child seated in the rear passenger’s side seat sustained lacerations to both legs. The rear middle seat occupant sustained a laceration to the rear head area, while the rear driver’s side occupant sustained lacerations to both arms. No injuries required medical treatment. The cause of the failure was not yet determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was 58,000.

I was driving at nighttime and my head lights cut off.. they were in auto light mode. I read that gmc knows about some sort of issue with this but only covers repairs up to 150k miles. My car is 156k miles. There was no warning lights and no indication anything was wrong. Luckily I was the only care on my side of the highway and was able to slam on the brakes and come to a complete stop. I turned the car off and then turned the head lights to manual and they can back on. A few hours later when I got home, I let the car cool off and turned the headlight back to auto and turned the car on and the worked.

The contact owns a 2019 GMC Terrain. The contact stated while approaching an intersection, the vehicle stalled. The contact stated that the check engine warning light was illuminated. The contact stated that a friend jump started the vehicle, and she was able to continue driving to her destination. The contact took the vehicle to an Auto Zone and was informed the fuel pump control module, enable circuit performance, and the passenger’s side seat belt switch circuit needed to be replaced. The vehicle was not repaired. The contact took the vehicle to the local dealer and made them aware of the failure. The vehicle was not diagnosed or repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 118,000.

While driving at the speed limit on U.S. Interstate 83 in Pennsylvania, my 2019 GMC Terrain's braking system suddenly, without any warning, became severely limited. The brake pedal suddenly became very hard to press and the my ability to slow or stop the vehicle became very difficult, requiring a great deal of pressure to even slow the vehicle. The braking system worked perfectly until that moment. If I needed to stop quickly or if I did not have as much leg strength, it is highly likely the equipment failure would have directly resulted in a catastrophic crash. I struggled to get the vehicle safely off the road and stopped. I then had it taken to a certified auto mechanic shop. There, it was found the GM vacuum brake booster pump had inexplicably failed, making the "brake assist" function inoperable. The mechanic was surprised GM had a replacement pump in stock, as he said that is not the norm for other brands. A moment after pressing the brake for the first time as the incident began, a message appeared on the dash stating "Service Brake Assist." There was no pre-failure warning or symptoms. I was in the middle of a 300-mile road trip, having already completed about 220 miles that day, without any notable incident. The cost to replace and install the vacuum pump was about $640.

My car automatic transmission is acting up when shifting from gear 5-6. It slips and it feels like the car is on Neutral for few seconds ( the engine RPM goes up to more than 4000 RPM)after it shifts to the 6th gear. When It shifts it feels like somebody hit us from the back. This is happening in internal roads, intermittently and on speed around 30mph. I'm worried this will cause the cars behind us to hit us when it happens. Everytime it occurs my baby starts crying. I'm concern about the safety of my family when we drive this car. I took the car to the dealership multiple times and they said that there's nothing wrong with the car.

I bought this car a couple of months ago. This problem didn't happen when I took it on a test drive from dealership. It happened after I bought it. Specifically when I start driving it more often. Sometimes a slipping occurs when shifting between gears 5-6. This happens intermittently on internal roads, not at high speed. When the car shifts the RPM goes up to 4000 RPM, sometimes even more, it feels like the car is in neutral for a few seconds, before it switches to the 6th gear. I have to remove my foot from the gas pedal to not let the RPM get very high. When this happens it feels like somebody hit us from the back. Last time my baby started crying when this happens. I'm a little concerned about our safety when we drive this car. The issue is that this problem is difficult to duplicate. Sometimes it happens more than once in 1 day and sometimes it doesn't happen for a while. I did some research online about similar cases with GM SUVs and some said that their problem was resolved after changing a defective valve Body and TCM and some said it's the clutch. It also can be transmission fluid but this car has a low mileage (28500) I doubt the transmission fluid need to be changed. Based on the GMC maintenance schedule, the transmission oil should be changed when this car reaches 45k. I took this car to the dealership multiple times, they check it and they tell me that they're unable to duplicate this issue. I'm not sure what else to do! I love this car. I'm disappointed that I had to deal with this issue that I believe is a safety hazard and could cause accidents. I need your help please!

I’m crying out to you because I bought a 2019 GMC Terrain in April of this year with about 14,000 miles. The suv ran great for about 2 months and since then I’ve been dealing with nothing but a nightmare. We’re dealing with a situation where the suv goes into park while driving. We’ve brought the suv multiple times to GMC dealership and even reached out to GMC, and had no luck resolving the issue. Last night, while driving to a family event, the suv went into park while I was driving. This is the 4th time since we got the suv. I’m scared for my safely in this suv, if you could please assist
