I was going at about 40MPH along a very busy main road. While slowing for a red light the Check Engine Light turned on and the car displayed a notice about reduced engine power. Seconds later, the brake pedal became stuck and would not press down all the way and I lost braking ability. The car rattled/shook violently, made a grinding noise, and then the engine shut off and the car stopped abruptly, narrowly avoiding hitting the car in front of us. I turned on the hazard lights. I was not able to get the car to start again, nor was I able to get the car to shift into any other gear including neutral. We were nearly hit by other vehicles multiple times while attempting to get the car to move again, and to get myself and my child safely out of the road. Myself and multiple bystanders attempted to engage the transmission interlock override multiple time. We were eventually able to engage it and push the car to the side of the road. This failure created an extremely unsafe situation for all involved as this road is very busy and there were numerous near-collisions both with my disabled vehicle, and with other drivers serving out of the way and into other lanes at the last second.  As time went on and the battery drained, most of the car's exterior lights turned off and other drivers had a hard time seeing my car. I used a strobe flashlight to alert other drivers but this required that I had to stand in the road near the vehicle. Police were called immediately when I found that we could not move the car out of the road, but they did not arrive. Ultimately the vehicle was stuck and inoperable in a travel lane for over two hours.  The car was then towed to a nearby repair shop. The mechanic evaluation stated that the brake vacuum pump had failed resulting in loss of braking ability and expensive damage to the engine and other components.  The manufacturer is aware of this issue. See: Thieme, et al. v.

While commuting to work in [XXX], my GMC Terrain experienced a sudden, catastrophic failure of the brake vacuum pump while traveling at highway speeds. When I attempted to slow down for the exit, the brake pedal instantly became extremely stiff and nearly impossible to depress. I realized I had suffered an absolute loss of power braking assist. To avoid a high-speed collision with heavy highway traffic, I was forced to deliberately steer onto the roadside rumble strips, relying on tire friction to slow the vehicle down. This severe near-miss left me terrified and distraught. Because the shoulder was narrow, my disabled vehicle was left partially protruding into the active roadway. Passing cars sped by so close that my vehicle was violently rocking, creating an incredibly unsafe situation. I was forced to call the State Police for emergency assistance. They dispatched a trooper and a tow truck to remove me and the vehicle safely from the highway.  The vehicle was towed to a mechanic in Massachusetts. The mechanic discovered that the vacuum pump had internally exploded. This explosion sent catastrophic metal shards and debris directly into the engines oil galleys and oiling system. While the vehicle has 121,776 miles, this is not a normal wear-and-tear component failure. The brake vacuum pump suffered a catastrophic internal mechanical explosion at highway speeds, completely eliminating my ability to stop the vehicle. A mechanical component failure should never cause an immediate, life-threatening loss of brake control, regardless of mileage. This is a known, systemic engineering defect that is currently the subject of active federal class-action litigation (XXX v. General Motors LLC). This defect did not just cause an immediate life-threatening braking failure, it completely contaminated the oiling system, destroyed the entire engine, and rendered the vehicle a total loss requiring a full engine replacement.

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.

I took it to my GMC dealer earlier this year for them to diagnose, and they discovered that the charge air cooler tube had collected moisture. Once that was fixed, the vehicle was fine for about a month when the same thing happened. I took it to another GMC dealer and found that the turbocharger wastegate actuator had to be replaced. Once replaced, I had no problems until it began to get cold where I live. Now the vehicle is doing the same thing. Now what happens is the engine light will come on and give the engine underboost message but goes away after a week of driving. I have taken it to 2 dealers for diagnosis, only for the engine light to disappear before they can figure out what the problem is now. This continues to be an issue, as I frequently drive on the highway over 55mph for work, errands, etc., and presents a potential hazard if I have to pick up speed and can't on a major highway.","products":[{"type":"Vehicle","productYear":"2020","productMake":"GMC","productModel":"TERRAIN","manufacturer":"General Motors, LLC"}]},{"odiNumber":11705510,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"12/13/2025","dateComplaintFiled":"12/17/2025","vin":"3GKALVEV7LL","components":"POWER TRAIN,ENGINE","summary":"The intercooler has been a document problem on GMC Terrains for awhile now.

We were also unable to put the car into neutral to push it off of the road the remainder of the way because the wheels were completely locked up at this point. The parking brake was engaged on its own. We also could not get the car into neutral. I had the car towed to a local repair shop, not knowing at all what the issue was. The vacuum pump had failed and broke apart in the engine. This caused my braking system to fail completely also.  The vacuum pump on my 2020 GMC terrain has been noted as faulty or defective.

The GMC mechanic at Jim Ellis Buick GMC diagnosed the problem as internal damage to the pistons, which they state requires a full engine replacement. They also confirmed an internal oil leak within the engine, which is contributing to bad emissions and further degrading vehicle performance.

In July 2022, I started to experience intermittent acceleration issues. The issue only presented itself upon vehicle startup and was very sporadic. Upon startup, the vehicle was very slow to accelerate even with the gas pedal depressed to the floor. The vehicle would move at an extremely slow rate of speed for approximately 10 to 15 seconds before the vehicle would engage and actually start moving forward at the expected rate of speed. This would happen 4 to 5 consecutive times before things seemed to \"warm up\" and run smoothly. It proved to be dangerous at intersections if making a left hand turn into oncoming traffic or during heavy traffic times. From the beginning of July to Aug 9th, this has happened on 5 separate occasions. The story is the same, I start the car after it has been sitting for a bit (it's been from several hours to several days) and the issue will present itself without warning. There are no fault or error codes. I've taken the vehicle to my mechanic as well as the dealership where I purchased the car and both have run diagnostics on the vehicle with no luck. My mechanic did drive the car and he experienced the issue first hand but he could not figure out what was wrong. In the event other Terrain owners are experiencing this same sporadic acceleration issue with no fault or diagnostic codes, I wanted to make sure we documented our issue. I did not record the dates of the first few instances but the last two have been July 24th and August 9th.","products":[{"type":"Vehicle","productYear":"2020","productMake":"GMC","productModel":"TERRAIN","manufacturer":"General Motors, LLC"}]},{"odiNumber":11468997,"manufacturer":"General Motors, LLC","crash":false,"fire":false,"numberOfInjuries":0,"numberOfDeaths":0,"dateOfIncident":"06/05/2022","dateComplaintFiled":"06/13/2022","vin":"3GKALPEV5LL","components":"UNKNOWN OR OTHER,VISIBILITY/WIPER","summary":"VEHICLE HAS 56801 MILES AND AIR CONDITIONING COMPLETELY WENT OUT. i HAVE ALSO REPLACED WINDSHIELD WIPERS TWICE IN 6 MONTHS.

I MADE AN APPOINTMENT. A DAY BEFORE THE APPOINTMENT I RECEIVED A CALL FROM THE DEALERSHIP STATING THAT AN EMPLOYEE RECENTLY PURCHASED THE SAME CAR AND THEY ARE HAVING SIMILAR DIFFICULTIES. THEY FOUND ONLINE THAT GMC WAS REQUESTING INFORMATION FROM DEALERS ABOUT THE PROBLEM AND WAS TOLD THAT I NOW NEED TO WAIT FOR GMC TO COME UP WITH A SOLUTION. MY CAR SHAKES EVERY TIME THAT I DRIVE IT, IT'S AWFUL, AND IT ONLY HAS AROUND 6,000 MILES ON IT. I'M NOT SURE WHAT TO DO BECAUSE THE DEALERSHIP TOLD ME THAT I HAVE TO WAIT FOR A SOLUTION. THEY ARE NOT EVEN TRYING TO FIX ANYTHING AT THIS TIME.
