I was driving home from vacation the vehicle went into limp mode and started to run very poorly with a brake pedal that was almost impossible to push. I limped the vehicle a couple of miles to the next exit. I had the car trailered home and taken to a service center the following Monday. They inspected the vehicle and found the vacuum pump had failed and caused what was described as “catastrophic engine failure.” They are now saying it needs a full motor replacement due to the widespread and severe damage. This is not the first time this pump has been an issue or supposed issue. About a year before this incident a month after we bought the vehicle in used condition from a GM dealership it started making a noise. We took it back to see if they could help us out being that it was recently purchased and they diagnosed it as the vacuum pump making the noise. They wanted almost $800.00 to replace it. I googled a video on how to fix it and found the cost of the part. The part itself is between $75-$90 from local and name brand parts stores. I paid the $250 diagnostic fee and took it somewhere else for a second opinion. The GM dealership pushed hard for the vacuum pump replacement and told me it was a well known issue for that part on that motor in many different makes and models. They said they recommend you change that mechanical part out every 80k miles or so and that you do not go by what the owners manual says for oil changes which is 5k miles and instead do that every 3k miles. That should not be “preventative maintenance.” That is a manufacturer issue. This should be a recall on the pump. I again did research and this vacuum pump is a known issue. You can find endless examples and discussions about it. It turned out not to be the pump originally that was making the noise saving me $800. The service center that has it now has all the pictures and pieces to show it’s failure and damage. It’s unsafe for something $85 dollars to cause that while driving at any time.

I was driving this morning and my car put itself in neutral. I think had to pull off to the side because it was not accelerating. I could get it to go over 20 mph. Every time I tired to accelerate. The engine would feel forced.

The manufacturer was notified of the failure but offered no assistance. The contact was referred by the manufacturer and was informed to contact NHTSA to report the failure.

Turbo Charge Engine

Driving on the interstate and got to a Toll the automatic stop start stopped the car and the car never came back on. The battery and starter started smoking and the engine has gone out. No explanation no nothing and the Mechanics at the Gmc Dealership stated it just happens with these engines they just go out! I purchased the vehicle on April 9th before I purchased it I had the dealership send it to a Gmc certified dealership to have it serviced. I've attached the paperwork from the dealership as well.

I bought a car from Boone Chrysler Dodge Jeep Ram dealership in North Carolina on [XXX] and by [XXX] my engine was out before I purchase my car I made sure they serviced my vehicle at a GMC Dealership and there's a warranty on the service of my engine I did not buy the warranty on my car because they couldn't guarantee that the warranty transferred over to West Virginia shop's and that they would cover issues they stated they could deny service cuz it was out of state. So my car went to Moses Cadillac GMC in downtown Charleston on [XXX] they literally just randomly dropped it back off to me two Wednesdays ago. I've been working with GMC to try to purchase a new vehicle and get mine bought back, but it's been a whole process but I'm trying to work with Moses so I can purchase a new vehicle but they won't call me back and i feel like its because they know something is defective. The engine had a Regen done before i purchased it and now all of a sudden the cars engine is Done. Now when this happened the battery got so hot my car started smoking we originally thought it was the starter. Because when it stopped working we were at a Toll booth and pressed the break and the stop start kicked the engine off and it never came back on. Even now if you try to start it the battery gets hot and the starter smokes. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Faulty vaccuum pump blew leading to engine failure. On the highway randomly, with my child in the vehicle. This almost caused a huge accident. I’ve kept up on all maintence and oil changes. This has been a huge effect on my life as I’m a single parent and randomly had to spend thousands on a new engine for zero fault of my own. I’ve read many many people having this issue. Something needs to be done and action needs to be taken!!!!!!!!

I’m crying out to you because I bought a 2019 GMC Terrain in April of this year with about 14,000 miles. The suv ran great for about 2 months and since then I’ve been dealing with nothing but a nightmare. We’re dealing with a situation where the suv goes into park while driving. We’ve brought the suv multiple times to GMC dealership and even reached out to GMC, and had no luck resolving the issue. Last night, while driving to a family event, the suv went into park while I was driving. This is the 4th time since we got the suv. I’m scared for my safely in this suv, if you could please assist
