This problem is on a lot of other years and models a lot of 2018 cars but not the terrain WTF!!!! My kids were in this car we were doing 65 MPH and trying to slow to turn onto our road to go home. I'm not a pro driver but I have been driving from age 9 and am now 45. If my wife was driving we would have all gotten hurt and wrecked the car. GMC is crap anymore for a car. If I buy an American car ever again it will be MOPAR never a GM again. And I was Raised GM my whole life. Sad times we live in move all the work to Mexico to save cash and skimp out on the real craftsmanship they had in DETROIT. GMC and GM need to go right to hell. So why all the other 2018's get a recall and terrain's and couple others don't? Someone need to die first ? Guess a gm chairman should have this problem. Bet they don't drive what they build!!! This fix is costing me almost 1500$ in parts and tools. I want GMC to pay me that all back. I make minimum wage MF's!
