This is the 4th time my vacuum pump has “broke” my brakes become hard and stiff and my brake assist light comes on. It happens EVERY winter when it drops below freezing. This is the second time this winter it has broke and now my check engine light is on. It is not cheap to fix and a major safety issue. Would like to add I was only backing out of my drive way this last time it happened. I was going maybe 5-10 mph.

The article below appears online, 4/13/2026. I have the exact same problem with my 2020 GMC Terrain Denali and I would like other GM vehicles added to their Chevy recall. They use the same parts within GM's product lines. As background info, I went to the dealer, Matick Buick GMC, 29300 Telegraph Rd, Southfield, MI 48034 on Jan. 14, 2026 for repair. I was told water infiltrated my backup camera and its harness. Matick said very few parts are available in the USA. Still not fixed and it is dangerous. Yes is the answer to the 1st 4 general guideline questions. The 5th question is NO. READ MORE TRENDING NEWS: Chevrolet has recalled 271,770 vehicles over an issue with the rearview camera. Some 2023 to 2025 Chevy Malibus were recalled because the camera screen may show a distorted or blank image, the National Highway Traffic Safety Administration said. Dealers will replace the camera at no cost to correct the issue. Owners will get letters in the mail alerting them to the problem after May 18, the agency said. For more information, call Chevrolet at 800-222-1020. The company’s internal recall number is N262551720. The vehicle identification numbers can be searched on NHTSA.gov.

It’s gonna end up getting me killed on the interstate. My vin also says it’s fwd it’s awd AT4 . Called dealer said only to update software clearly not the issue. My doors are off and they have refused to fix those for over 30,000 miles now. It won’t let me attach any pics for some reason I’ve tried since yesterday

- #11728525April 1, 2026SUSPENSION, STEERING, SERVICE BRAKES
My SUV pulls hard to the right when braking at speeds above 50 mph and much more on the interstates at 65 mph and above. I first experienced this after three weeks of ownership on a drive up I-95 on a trip to NC. It has happened numerous times while traveling on the interstates and has almost caused loss of control when having to brake hard when cut off by another driver or traffic suddenly coming to a stop. The vehicle has been to the service department numerous times....at first they suspected a braking issue and have had both calipers replaced, all brake lines replaced, lower control arms replaced and the right side strut replaced. None of these repairs have solved the problem. The factory service rep who took over the situation tested 3 other GMC 2025 Terrain suvs and all had the same problem. He reported the issue on a safety report to GM in Michigan and the response from GM was that it is a normal condition for the Terrain models. I have never owned, driven, or ridden in another vehicle in over 50 years of driving which performed like this, this is not a normal condition in my opinion.

Have had to replace the VVT solenoids several times within a year spam. Had to replace the rear main seal because it blew out due to carbon build up. Having issues with excessive oil consumption. Now the vehicle just started with: going from a stop position to accelerating at low speeds the vehicle stalls and dies. I want GM to take accountability and fix this issue as it is a safety issue to myself and everyone on the road.

1- at 71,000 miles in 2022 brake vacuum pump “exploded” broke into many small pieces in the middle of driving. Causing brakes to lock. Brake pedal was brick hard. Hard to maneuver the car out of traffic without causing a collision. Luckily car was not being driven at high speed. At time of repair costing $1,000 Mechanic informed me that the pump was made out of a non metal material and he could not fish the small particles out of the motor with a magnet. The motor would need to be taken apart, cleaned out and reassembled….. From this point forward the car drives in “low engine power mode” even with repairs completed and codes cleared. 2- 2 years later the same part “brake vacuum pump” exploded again. Another $1000 repair. At this time we discovered that the fine particles that were not removed from motor has now knocked the timing off by 8%. Also it has caused a knick in a seal causing an oil leak under 100k miles $1800 repair. After these extensive repairs…… The car emits gas fumes into cabin. The smell is so strong it can’t be parked in the garage because it circulates through the house. Even when car is not running. The Car can’t be driven because risk of fire or explosion from gas. Fuel system gets cleaned. Injectors replaced. The car temporarily runs without the gas smell. 2 weeks later the gas smell returns Come to find out the fuel pump failed. Search online and find there is a recall for fuel pumps in this same make model and year. But not this vin number. The car has been a headache from day 1. Recall the whole car at this point, to have so many faulty parts in such major systems of a car is crazy.

The contact's husband owns a 2022 GMC Terrain. The contact stated that while driving at 20 MPH, the vehicle shut off with the message "Press Brake Pedal to Start" displayed on the instrument panel. The contact attempted to restart the vehicle several times and added fuel to the fuel tank jug; however, the vehicle failed to restart. Due to the failure, the vehicle was towed to an independent mechanic who diagnosed the vehicle with a defective fuel pump module. Upon investigation, the contact discovered NHTSA Campaign Number: 23V013000 (Fuel System, Gasoline); however, the VIN was not included in the recall. Neither the manufacturer nor the dealer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 60,000.

My Transmission went out of my truck. I was told this has happened to others of the same make and model, so this is a known issue with this transmission. I was driving down the road and the car completely stopped in moving traffic. I was almost hit by other vehicles and then had to take my truck to get it repaired. I was told it was not able to be rebuilt that it had to be completely replaced. This is radiculitis since this vehicle is not that old and again a known issue. I want to be sure mine was listed as one that had to be repaired in the event a recall is done so that I may get my money back.

Out of nowhere and driving this morning, my engine reduced power came on. Then I started losing power in the car then it died on me once out of nowhere. I managed to make it home an hour and a half later, but that could’ve got me killed stopped by AutoZone since dealerships closed today and it tells me that it’s code P228C, P0089 fuel pump. And then last night my emergency service calling came on which one I looked it up so something to do with OnStar and could be a module so I’m not sure what that is. And then you add on the fact all the sudden in the last 24 hours, my screen keeps going in and out are not working last week. My volume wasn’t working. I love this car, but it seems to have a lot of issues all of a sudden and I’m fixing to be at 60,000 miles which is a big problem considering warranty will be expired. I’ve already had issues with squeaking and squealing from the windows that they claim they can’t find nothing and I’ve had to listen to it for almost 60,000 miles. I had to get this car because my other car blew up on me and I can’t afford another new car. I’ll be taking it to the dealership first thing in the morning and I hope to God that something can be fixed cause we’re in one car Family.

With no warning signs, vehicle abruptly stalled while driving. I attempted to restart multiple times. Finally restarted and drove another 100ft and stalled again now with a check engine light. Made it to local shop and code P129F was found for fuel pump module. I see there is a recall on this but not for my particular vin. Recommend expanding recalls.
