2019 GMC Terrain

In July 2022 vacuum pump failed and created a hard brake situation going 55 mph downhill. Vehicle removed from roadway safely, transported and vacuum pump replaced. In May of 2023 vacuum pump again failed driving at around 25mph, vacuum pump failed catastrophically and blew up inside cam cover. Taken to garage via flatbed and reported car needed a new engine or alternatively we could try a new cam and vacuum pump with hopes pieces did not make it into engine. Now vehicle sits while I still owe money as I do not have 3-5000 to repair it. The fact that this is such a common issue and has happened frequently with other GM models is criminal. I feel as if GM should offer a buyback on affected models or reimburse customers for damages done. Vehicle is outside of warranty currently at 83k first vacuum pump failure occurred at around 70k.

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

Brakes failed on my car while driving and ran through 4 way stop. Took car to dealership and was told the vacuum pump seized up and sheared off. Asked the dealership what caused the problem and all they could say was normal wear and tear of the vehicle. Dealership called and said it was going to cost $900 dollars to fix the problem. I asked what that included and they said a new vacuum pump and to clean the motor out. Picked the car up on Monday and by Tuesday evening car would not run. Took it back to the dealership and am now told I need a new cam shaft which cost another $2400 to fix. This is a serious safety concern as I had no warning or received no notification that the brakes had failed just went to stop and could not. How long is GMC going to let this issue go before being addressed. How many people have to die first before they recall them as the have already recalled the bigger models of gmc, Chevrolet, Cadillac and Buick for the same reason? I don’t know how people are suppose to afford to fix an almost brand new vehicle that they are still making payments on.. Something should be done ASAP...

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.
