While driving, the vehicle suddenly experienced a vacuum pump failure that caused a severe loss of braking ability with no warning beforehand. The brake pedal became extremely hard, and the vehicle would barely stop. This created a very dangerous situation and could have easily resulted in a serious accident.  Thankfully, I was not driving at a high speed when the failure occurred, and there were no vehicles directly in front of me at the time. However, only minutes earlier I had been traveling approximately 65\u201370 mph on the highway. If this brake failure had occurred while driving at highway speeds or in heavy traffic, I truly believe it could have caused a major crash resulting in serious injury or death.  What concerns me most is that there was no warning before the brakes failed. No warning lights and no issues with my brakes. The sudden loss of braking power was extremely frightening and created an immediate safety hazard. After researching this issue, I discovered that other GMC and GM vehicle owners have reported similar vacuum pump failures and brake assist problems.  I believe this is a significant safety issue that should be investigated further. Drivers should not experience sudden brake failure without warning, especially on a vehicle that otherwise appeared to be operating normally beforehand.  I am very thankful no one was injured in my situation, but I am concerned that another driver may not be as fortunate.  My vehicle had to be towed to a nearby shop and they suspected it was the vacuum pump failure and the car started smoking badly. so I had it towed to the GMC dealership and they called me today to confirm that was the problem and it also caused damage to the camshaft. This is a known issue with the terrain and there is currently a class action lawsuit.","products":[{"type":"Vehicle","productYear":"2020","productMake":"GMC","productModel":"TERRAIN","manufacturer":"General Motors, LLC"}]}]}
