    I have been notified that my brake vacuum pump EXPLODED in to my engine, leaving me with limited braking ability. I was driving through a school zone when the brakes went out, I noticed as I was not able to stop at an intersection. This could have led to multiple injuries, including children being in harms way. I had no warning this was coming and now look towards a hefty repair bill. GMC has recalled vacuum pumps in other models but for some reason the terrain is not included. I wonder if there just haven't been enough deaths caused by faulty brake systems for them to cover this model too.

    GMC Corporate Office General Motors Company300 Renaissance Center Detroit, MI 48265 To Whom it May Concern, Been a customer with GMC for a good while despite the issues and troubles we were still loyal to the company. October 31,2021 Sunday, I had sudden lost of my brakes/stalled on my 2019 Terrain SLE while driving to the store close to my area on top of that having less than 30,000 miles in it. Despite the horrible and devastating event I was able to have the truck without any scratch , hit , or had any accident on this event but instead still safely stopped the car down a hill from where I lost my brakes/stalled. Fast forward Nov 2nd had the truck towed to the Milea Pontiac Buick GMC Service And Parts at 3281 E. Tremont Bronx New York 10461. Towing company both from picking up the truck and dropping off Milea had a hard time since the truck was not starting or even able to be placed in neutral to be able to have the truck roll of the flatbed. Nov 2nd Tuesday 2019 GMC Terrain was dropped off at Milea Service and Parts. 1st issue identified by your crew (sort of technical experts) was a bad battery and needs to be replaced, 2nd problem was the computer need to be replaced, 3rd problem was that I had put BAD gas into the tank and the fuel pump need to be replaced after 9 days so fast forward now to Nov 9, 2021.Now finally spoke to a mechanic now stating pistons doesn’t seem to be firing but does not have proper tools to do the test is trying to get from another dealer to be able to diagnose the problem. Nov 20, 2021, still no news as to what is the real issue on the truck we again visited the Milea to find out what is the deal and still without a truck from Nov 2nd to Nov 20 still yours truly has no loaner and no written nor verbal confirmation of what really cause my lost of my brakes/stalled truck. Linda Cuomo the Milea representative has nothing to inform us regarding the cause and instead waiting for a specialist from out of town which claims to be the e

    The Back Up Camera System is not working properly. When Vehicle is put into reverse a blue screen appears. This can be dangerous as one could back up into someone or something. This is a 2019 vehicle and the NHTSA made them mandatory in May of 2018. This has been confirmed by a dealership. Many others have posted this online as an issue and GM has put out this service bulletin: https://static.nhtsa.gov/odi/tsbs/2019/MC-10160418-9999.pdf

    I received a "service brake assist" message which came on then off. Took the car to a local mechanic who looked it over and said to see dealer as they saw nothing obvious. internet search revealed that many people with terrain said this warning came on when battery was low. Made a service appt for NJ dealer for 12/6/21. on 12/3/21, began a 1200 mile drive from Florida to NJ, after 2 hours, check engine light came on. Took the exit ramp from I 75 and at end of ramp, there was a total braking failure. I had to press very hard to eventually stop. Shut off car, attempted to restart but it would not. Towed to a mechanic who found fluid leakage and a repair bulletin on GM site involving vacuum seal camshaft. #pip5598A diagnostic tip. Internet search reveals many anecdotal instances of same problem. On Monday, 12/6/21, I received an email from GMAC saying that the on board diagnostics had shown a "low battery" concern. The catastrophic loss of braking seems to be connected to a low battery situation. This needs to be looked into by NHTSA.

    My wife was driving the car, about 70 mph on route 84 passing danbury ct. She was traveling in the middle lane, some kind of oil light went on the dashboard, car shut down while traveling 70 mph on the highway, and caught on fire under the hood. She managed to pull over, and got out of the car with my daughter. This is a 2019 car with 14K miles. This car was packed with milwaukee cordless tools, complete Festool set, complete golf bag with all the clubs, two suitcases of best clothes for me and my daughter, her laptop, etc. We were driving to our new home in south carolina, and on the way the car burned.
