I was exiting off the interstate and all of a sudden my brakes got hard and wouldn-??t let me stop. I tanned thru a red light barley missing another vehicle. The dealership says my vaccines pump went out and caused it to strip my valve cover gasket to shreds and now has stripped the gears in the camshaft.
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.
While driving the car cut off on us. Started the car and the dash lights were on. Also Navigation stopped working. Took the car to bellamy Strickland and they said no issues was found. Got the car back 12/02_2021 Car seems to be ok at the moment. Melissa at bellamy stated it could have been a computer glitch. Car only has 20k miles on it.
My 2019 GMC Terrain has 21K miles and noticed a oil or transmission leak this morning. I see recalls for other vehicles but none for mine. Linking from a bolt just as the other recall is for.

Found bulletin 19-NA-181 which was very close to all symptoms and stated to check for chaffed wires near the ECM. Found no spots in the tape where it was rubbed through but lost comms when wires were shook. Unwrapped main engine harness loom and inspected wires, found nothing. Started TAC Case # 9-6385087421 and was told it probably is a chaffed comms wire somewhere and gave me multiple locations to check. Found no damaged wires in those locations and shaking main harness no longer would make it fault. Put it all together and drove it down the road and faulted immediately. Unwrapped main harness again snd sprayed with saltwater to help conductivity but still couldn't get it to fault while shaking the harness. Only way it will fault is when shifting into drive the drive train bumps just right to bend the right wire. Checked every wire I could find and can't find the problem wire. Not drivable. When this vehicle faults it will not shift past 1st gear and sometimes locks out reverse. Must be towed. Needs the main wiring harness to start, recommend customer to authorize FSE to dealership CUST declined., all the lights and messages were coming on over the dash.

I purchased a 2019 GMC Terrain VIN: [xxx] on Jan 17, 2019 at rizza Buick GMC 8415 w. 159th street, tinley park il, 60487, on January 17, 2019. This was my first brand new car and I was excited. I traded in a 2014 GMC Terrain in the process, knowing I would be upside down on the loan. I had the first service done on April 23, 2019 at said dealership. At that visit I explained that I was hearing a noise on the passenger side vent even when the HVAC was not running. I was told nothing was detected and my vehicle was fine on May 24, 2019, I drove my vehicle to memphis Tennessee with my family for memorial day. On May 25, 2019 the check engine light came on, I was losing power to the engine. That same night customer service towed my vehicle to sunrise Chevrolet Buick GMC, 1800 covington pike memphis, Tennessee 38128, a nearby GMC dealership and set up a rental car in the area for me to drive. Because it was the holiday, enterprise was closed, and I had no vehicle to drive for two days. This was an inconvenience to me and my family, I had to alter my trip plans that were made back in February 2019. On May 27, 2019 I was told by [xxx] the technician at sunrise Chevrolet that air box tube was loose and not properly installed and could have been done during my service I had done April 23rd. I was assured everything was okay and I was good to go. On May 31, while traveling back home the check engine light came on again. Same message on the dash and it was raining at 3am. I was close to home and was able to make it to the dealership that I purchased it from. My vehicle has been in service since May 31, 2019 and I am just finding out that I have a part that is on national back order. I am not satisfied with my experience an I am reaching out to you to resolve this matter. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
I have a 2019 GMC terrian with 2500 miles. I was driving it and the car flashed low fuel, check transmission and check engine warning and shut down while I was as a highway speed. I was fortunately ok, however it stranded me at a spot with merging traffic, no shoulder and no power to get the vehicle out of there. The vehicle was able to start up shortly, then I had to deal with getting going again in this precarious spot.
