When turning right or left from a stop, the steering wheel jerks sharply in the opposite direction as soon as the car starts to accelerate. Diagnostic tests and inspection determined that the steering gear is loosing voltage causing the jerk in the steering wheel. The gear has the latest calibration and needs to be replaced. Cost estimate to replace is $2035.63

There are 3 recalls and one open on this car I was sold by a dealership, none of them ever fixed. I drive to work in the highway the car never had any warning light on but the RPMS would occasionally go up for no reason. I told the dealership the second day that it had issues , they took it and say they fixed the back brakes but did nothing about the engine or transmission whatsoever ever. This was the beginning of may and it was in the shop two weeks. I called my lender to even get out of the loan and a saleswoman even tried assisting me into talking her manager out of the loan because of all the issues. Fast foreword to august I had just gotten a new job and was driving in the night after hearing that ticking or slight knocking noise and I went to my job and as i tried to park the brakes went completely stiff on me! I could not get the car to slow down I had to weave through other cars and people in till it finally coasted to a stop. So I put it in park and immediately after the check engine light came on. I tried to start it and it would start , putter and turn off over and over. I had to end up calling OnStar to have a diagnosis which she said something like solenoid and something being clogged. So it was towed to my residence and before i could get it towed to s shop they lender came and repossessed it because I had missed payments due to losing my job unexpectedly, completely unexpectedly. I told the lender of the problem and the unfortunate troubles I was having to pay for the car but I had just landed a job and could start payment but she didn’t care. She said she is going to tow it . I had my friends dad who is a licensed mechanic look at it before it was towed and he said the car was trash , basically a lemon that there was oil clogged and instead of passing through like it’s supposed to do it being pushed the opposite way and ending up in other reservoirs it shouldn’t be in. I obviously didn’t do that type of damage oil and trans problems I was scammed

2019 gmc terrain with 45000 miles, regular maintenance performed. Driving on highway 70mps brakes failed with no warning. No issues with brakes or lights coming on up to this point. Brake pedal became stiff very minimal brake working lights began flashing on dash stating "service brake assist". Barely made it off the highway without a catastrophic Collison. Took car in states brake vacuum pump completely failed. Apparently there are many models of gmc/chevy that were recalled and have known issues with the brake vacuum pump. Not sure why the terrain is not included. It needs to be, this was a very dangerous situation. I had children in the car and was very scary! 600$ to repair, and from reading other reviews the pumps are breaking often, sometimes ruining engines. Gmc stand behind your product and fix this!

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.
