Driving home from dropping my daughter off at school. When slowing down at stop sign, car locked up brakes completely, almost went through stop sign, car shut down engine and placed vehicle in park. Diagnosis is a vacuum pump failure, causing reluctor wheel to spin freely from camshaft. This happened without warning at 70k miles. Diagnostic report from three weeks prior showed no bad diagnostics with engine or drivetrain components, or brake components. Had to have car towed from intersection where i was impeding traffic due to sudden failure. Garage is concerned regarding potential for debris and engine damage, as well as timing issues due to sudden failure of vacuum pump. GM has authorized vacuum pump recalls on other makes from prior years, not Terrain for some reason. This is how becoming highly reported failure among GMC/Chevy vehicles with shaft driven vacuum pump design between 2019-2022. GM has stopped using this design on 23 and newer models. They should absolutely recall these older models for this issue. Sudden vacuum pump failure can lead to unrepairable engine damage due to design.
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 was riding on the freeway when my brakes failed. i was not able to press down on my brakes with zero warning. I had to swerve to miss cars and pull on the shoulder of the freeway and my car still would not slow down. I finally got from 65 to 35 and pressed on my emergency brakes. I stopped the vehicle then my engine light came on and I got my car towed to the car shop where my car would not stop and suffered internal damage to my engine from the brakes and vacuum pump
The contact called on behalf of her husband who owns a 2019 GMC Terrain. The contact stated that while her husband was driving approximately 50 MPH, the brakes seized, and the contact veered off into a lot to park the vehicle. The vehicle was towed to an independent mechanic where the vehicle was diagnosed. The contact was informed that the brake vacuum pump and the timing chain needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 72,000.
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)
on two occasions the vacuum pump booster failed causing the vehicle to lose braking ability while traveling on a highway at highway speeds. The vehicles brake completely failed and were unable to be engaged. the part was initially replaced by the dealer at the owner's expense and then the same issue occurred only a few months later. the second occurrence cause additional damage to the camshaft and timing chain causing the vehicle to not even be able to start. The vehicle was inspected by the servicing dealer and found metal shavings in the oil as well as extensive damage to the engine.
My daughter was driving her 2019 GMC Terrain at 15 - 20mph when she suddenly lost her brakes. Fortunately she had just turned into a new housing development where the road ended into an empty field. This could have been catastrophic for her & other citizens on the road. The following morning she would have been heading to work on a highway with heavy traffic with a posted speed limit of 65mph. We towed the vehicle home & after some investigating I found a vacuum pump failure. This vacuum pump broke apart internally sending chunks & shards of metal into her valve train. This issue is mentioned several times in Terrain forums & someone needs to address this issue before it becomes a fatality.
Engine overheating, cooling system contaminated with engine oil. Originally brought to dealership [Crown Buick GMC - 2121 Clearview Pkwy, Metairie, LA 70001 - (504) 302-8979] November 27, 2023. However, they were unable to identify the problem. Since the engine continued to overheat, brought the vehicle to an independent mechanic [EFI Services, Inc. - 5720 Heebe St., Harahan, LA 70123 - (504) 734-8200] January 25, 2024. They shared Service Bulletin 22-NA-240 and said it should be covered under powertrain warranty. Brought it back to the dealership [Crown Buick GMC] January 19, 2024. They informed me Bulletin 22-NA-240 did not apply to the vehicle year (2019) was not included. They also informed me no work would be covered under warranty because it expired December 18, 2023. I continue to have to refill the coolant due to overheating, and oil is clearly present.
Vaccumm pump failed and broke metal shavings off into engine resulting in -??engine failure-??. I was driving on the highway with my 6 year old child in back seat, car completely shut down and shot a -??reduced engine power-?? message while on a busy on ramp heading onto highway. This created an extremely dangerous situation for myself and my child as many cars almost smashed into the vehicle. I-??ve seen many other complaints of this happening, the same exact parts and issue happened to the Chevy Equinox which resulted in a recall but they have yet to recall the Terrain, which is having the exact same issue. I am a single mother, with 20k still on my loan. This mistake made by gmc has now costed me over 5,000$ out of pocket for something that is not my fault and completely out of my control. Even after all of the money poured into this repair, I still feel unsafe in my own vehicle as there is no guarantee this issue will not happen again. I-??ve kept up on all oil changes and maintenance of my vehicle. The issue was confirmed by a GMC mechanic which cost 500$ out of pocket for diagnosis as well. I also had to spend 1000$ on a rental out of pocket because of this. I have seen many others complaints of the same issue happening to their GMC terrain and am appalled no recall has been discussed after the reaccuring issue. I should not be having to pay out of pocket for an issue GMC has yet to fix or issue a recall on. I had to miss days of work, and it really was a huge inconvenience. I do not feel safe in my own vehicle even after the repair, cause I have no guarantee this won-??t just happen all over again.
While driving on 95, I lost all engine and power breaks with no warning. A message came up on my dash stating that I had lost engine power. Fortunately an exit was up ahead so I was able to get there and coast down the ramp. I attempted to make a right turn to get out of the way but ran out of momentum. Dealership stated my vacuum break pump failed and went into the cam shaft. They had to replace those and the solenoid actuator and value. They also conducted an oil change. I received it back yesterday, started the car today and the check engine light was on. They found more debris and replaced another point and said if the light comes on again it's the timing chains in the engine. I went out leave and the check engine light was on. They are now keeping it to repair the timing chains. I am fighting with GM to cover the expenses since I see this is an issue in previous models/years of GMC and Chevy vehicles.
For the third time, the brake booster has failed on our GMC Terrain. We had the first replaced with an OEM part. That booster failed after 2 weeks. A second OEM brake booster was installed. That one lasted about a year until it failed as well. This time we were traveling down the interstate and interstate speeds. There were no indications of an issue until trying to slow down when attempting to exit the interstate. Luckily it was a long ramp and there was not much traffic as I had to push extremely hard to slow down the vehicle. Knowing immediately what had happened, we noticed a GMC dealership was just down the road and safely made it. We left the vehicle at the dealership and rented a car to continue our vacation. We are now being told that not only did the brake booster fail, but the components entered the engine and caused major damage. The suggested repair is a full engine replacement. This is unacceptable for an issue that GMC has know about and has had recalls for on other years of their vehicles. Not only could my family have been severely injured, or worse, we are not financially able to repair the vehicle.
My 2019 gmc terrain, vaccum pump failed at about 45000 miles, was driving on the highway and brakes were hard to stop, almost crashed. About 52000 miles, vacuum pump failed again, also while driving on the highway. Brakes were hard to stop, again almost causing me to crash. 69000 miles again vacuum pump failed while driving on the highway, again almost causing me to crash. All times pump was replaced under warranty and now this has caused my engine to fail. i was denied factory warranty, pre certified and extended warranty. Now im stuck with a car with with three years left to pay on
In July 2022 vacuum pump failed and created a hard brake situation going 55 mph downhill. Vehicle removed from roadway safely, transported and vacuum pump replaced. In May of 2023 vacuum pump again failed driving at around 25mph, vacuum pump failed catastrophically and blew up inside cam cover. Taken to garage via flatbed and reported car needed a new engine or alternatively we could try a new cam and vacuum pump with hopes pieces did not make it into engine. Now vehicle sits while I still owe money as I do not have 3-5000 to repair it. The fact that this is such a common issue and has happened frequently with other GM models is criminal. I feel as if GM should offer a buyback on affected models or reimburse customers for damages done. Vehicle is outside of warranty currently at 83k first vacuum pump failure occurred at around 70k.
When trying to accelerate, the car will not accelerate. It will start to jerk back and forth and I had cut it off completely in the middle of the road at a stop light.
The contact owns a 2019 GMC Terrain. The contact stated while approaching an intersection, the vehicle stalled. The contact stated that the check engine warning light was illuminated. The contact stated that a friend jump started the vehicle, and she was able to continue driving to her destination. The contact took the vehicle to an Auto Zone and was informed the fuel pump control module, enable circuit performance, and the passenger-??s side seat belt switch circuit needed to be replaced. The vehicle was not repaired. The contact took the vehicle to the local dealer and made them aware of the failure. The vehicle was not diagnosed or repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 118,000.
The car cuts off during driving and when u crack it back up the dash light do not work. But then the dealership said its a known issues but the car just needs to be reset...... but cutting off while driving can be dangerous. It's something a car should not
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
Vacuum pump went out while getting off the freeway, going around a roundabout. Brake petal extremely hard to depress and was unable to slow down or stop in a timely manner. Tooke vehicle to GMC for diagnostics and they said the vacuum pump shattered causing damage to my cam shaft and possible engine damage.
Brakes failed on my car while driving and ran through 4 way stop. Took car to dealership and was told the vacuum pump seized up and sheared off. Asked the dealership what caused the problem and all they could say was normal wear and tear of the vehicle. Dealership called and said it was going to cost $900 dollars to fix the problem. I asked what that included and they said a new vacuum pump and to clean the motor out. Picked the car up on Monday and by Tuesday evening car would not run. Took it back to the dealership and am now told I need a new cam shaft which cost another $2400 to fix. This is a serious safety concern as I had no warning or received no notification that the brakes had failed just went to stop and could not. How long is GMC going to let this issue go before being addressed. How many people have to die first before they recall them as the have already recalled the bigger models of gmc, Chevrolet, Cadillac and Buick for the same reason? I don-??t know how people are suppose to afford to fix an almost brand new vehicle that they are still making payments on.. Something should be done ASAP...
