SERVICE BRAKES, ENGINE
Our son and two daughters were driving on the highway at approximately 70mph when a message came up to say the engine was in "Reduced Engine Power". Although nothing seemed to change. The instruction for such and error message is to "get vehicle to a dealership within the next day." So they slowed to 60mph and continued on their way. About 8-10 minutes later another message popped up that said "Service Brake Assist", at which point they immediately tested the brakes and they worked. But 2-5 minutes later they tested the brakes again and the brakes had completely failed! Zero brakes on the highway! No matter how hard the driver pushed the brake pedal there was 0.0% response. So luckily they were able to coast down to about 10 mph with hazard lights on. But at that point they lost everything. No power steering, no engine, and zero brakes. Thank the lord that they were able to have enough room to slow down and get over to a shoulder prior to the loss of power steering and that they had enough room to coast to a stop. Please help, as we were extraordinarily lucky that day that 3 of our children were able to walk away from such a catastrophic vehicle failure. I just do not want that to happen to anyone else.

AIR BAGS
The Safety Restraint System warning keeps coming on and off as well as the air bag light. It happened months ago so I took it in and got it looked at and scanned. All the seatbelts were checked and the scan came back with nothing. Then it stopped for a couple months and now it has started again. Ive had 14 surgeries in the last little less than 4 years and I'm about to go into my 3rd back surgery since November. I cannot get into an accident and not have airbags as I've also had brain surgery 3 winters ago as well. I am disabled and do not have a ton of money either for fixes that aren't necessary but this safety issue is crucial to me. I see that many 2018s have been recalled for the exact same issue that I'm having however mine doesn't come up with that but it is happening to me so that should be included. I also need some direction if not as to why this is happening because I cannot afford to have a dealership, no less, replace every tiny little thing looking for the culprit at $150 an hour when I live on $1,200 a month and most goes to medical. Please advise on what to to or where to start. Thank you.

POWER TRAIN
In January 2022, I purchased a 2020 GMC Terrain from a local GMC certified dealership along with an extended warranty. In July 2022, I started to experience intermittent acceleration issues. The issue only presented itself upon vehicle startup and was very sporadic. Upon startup, the vehicle was very slow to accelerate even with the gas pedal depressed to the floor. The vehicle would move at an extremely slow rate of speed for approximately 10 to 15 seconds before the vehicle would engage and actually start moving forward at the expected rate of speed. This would happen 4 to 5 consecutive times before things seemed to "warm up" and run smoothly. It proved to be dangerous at intersections if making a left hand turn into oncoming traffic or during heavy traffic times. From the beginning of July to Aug 9th, this has happened on 5 separate occasions. The story is the same, I start the car after it has been sitting for a bit (it's been from several hours to several days) and the issue will present itself without warning. There are no fault or error codes. I've taken the vehicle to my mechanic as well as the dealership where I purchased the car and both have run diagnostics on the vehicle with no luck. My mechanic did drive the car and he experienced the issue first hand but he could not figure out what was wrong. In the event other Terrain owners are experiencing this same sporadic acceleration issue with no fault or diagnostic codes, I wanted to make sure we documented our issue. I did not record the dates of the first few instances but the last two have been July 24th and August 9th.

ELECTRICAL SYSTEM:IGNITION
The key can be removed from the ignition in P, R, N, D, and M after the vehicle has been shut off. The vehicle does not provide any warning that the vehicle is not in park prior to allowing you to remove the key. The vehicle does not indicate the vehicle is not in park after the key has been removed. You are not able to start the vehicle if the vehicle is in anything other than park. I contacted GMC to inquiry about this issue and was told my vehicle’s VIN is not included in the recall for this known issue.

ENGINE
Excessive oil consumption, on average this vehicle is burning off 2 or more quarts of oil over approximately 1,000 miles. The vehicle is also hard idling, jerky and lunging forward at a stop, hard shutoff where the engine does not immediately shut off when the key is turned off and the entire engine shakes until it sounds like it stalls out. The vehicle also accelerates slowly with high RPMs, approximately 3500 RPMs before shifting gears. Check engine light turns on and off when it has been over 2500 miles after an oil change and when the gas gauge reads 1/4 of a tank or less. The diagnostic tool plug does not register anything; does not even turn the diagnostic tool on when plugged in. This vehicle has also stalled out while driving with no warning lights or indicators. I called GMC on 8/9/22 to inquiry about these issues and was informed my VIN is not included in any recalls or special conditions related to these known issues.

UNKNOWN OR OTHER
There is a rattle in the b pillar/roof area. They have attempted to fix it 4 or more times by adding adhesive between layers of metal. The fix that other dealerships have done per reading online involves cutting through metal. This would affect the integrity of the body/ frame of the car.

VISIBILITY/WIPER
my windshield wipers just suddenly stopped working during a rain storm. I managed to get home safely and after a quick search I was able to confirm this is a known problem with GMC Terrain's. It is talked about in Special Coverage N192266180. However this happened during a rain storm with limited visibility. So I am filing this complaint because GMC needs to issue a full blown recall and not a fix for after the windshield wiper system module breaks. Failed wipers during a storm could get people killed. I was lucky but others may not be. I took video of the wipers not working during the storm if you wish for me to send it to you.

SERVICE BRAKES
While getting off the interstate, the brakes failed with no prior warning, or issues. The brake pedal became extremely difficult to depress and stopping distance was greatly increased. Could not come to a complete stop without using the emergency brake. We drove home (about 2 miles from the interstate exit) and about a half mile after the brake failure, a "service brake assist" light illuminated. Vehicle was towed to dealership the next morning. The problem was the vacuum pump exploded and caused vacuum to the brake booster to be lost, making the pedal difficult to push. Luckily this happened at 11pm and there was nobody in front of us, there definitely would have been a collision.
