SERVICE BRAKES
When car has been unused for a period of time, the right rear brake makes noise when the car is moved. This happend in either forward or reverse. Even after driving for a short period of time, the noise is still evident. Under warrenty, I asked the dealership to resolve. They indicate this is an ongoing investigation by GM. I purchased the car new in July 2021. This problem has persisted since purchase. I have reported it multiple times to the dealer but they pass it off as GMs problem. In reviewing other similar complaints for the 2020 model, it was resolved by changing the brake pads to a different material. Surely GM can find a cure after 3 years since production.

Twice had to have wiring repaired because animals ate the wiring. Both were caused by GM using soy based insulation on wiring that made it a delicacy to the animals and caused them to eat through two wiring harnesses, one of which GM no longer makes. The other complaint is the timing belt has stretched and is now in need of replacement at a cost of $4500 to $5000.

ENGINE, UNKNOWN OR OTHER
While driving, my vehicle makes a loud funny sound, jerks/skips, and shuts off. It also loses motor oil quickly, yet it has no leaks and I have to constantly add more motor oil or get oil changes frequently. My safety has been put at risk because the engine can fail at any moment due to no motor oil, causing the vehicle to catch fire and also when the vehicle suddenly stops and shuts off in the middle of the road, it can cause an accident. There has been no inspection from the manufacturer.

ENGINE
Vehicle repeatedly stalled while on highway, there were no warning lights on dash or anything indicating of an issue prior. Took vehicle to repair shop and after thorough investigation they reported that there was no oil in engine despite dashboard monitor registering oil life was fine. Oil changes are always completed regularly and on time for vehicle. Mechanic said that this is a known issue with GMC for this specific model where oil is consumed at an irregular rate. There is a lawsuit against gmc for oil consumption that includes years 2010-2014 where gmc was at fault however the lawsuit was filed before the 2017 model came out. It was later discovered that years ,2014-2017 also have this known defect however a recall has yet to be placed. Being a common symptom of this issue is frequent vehicle stall this really should be a recall. After speaking with a couple of other gmc dealerships they were aware it was a frequent issue as well but are uncooperative when it comes to the cost of repairs, an entirely new motor is needed to be replaced now for the vehicle being driven without oil. After several calls with a GMC representative I was advised to file a complaint with NHTSA to have you guys complete an investigation into the issie

FUEL/PROPULSION SYSTEM
On Wednesday, June 26, 2024 my 2020 gmc terrain unexpectedly malfunctioned and failed to restart. The engine light came on and I attempted to restart it for nearly 2 hours with no success. Fortunately, it finally started and once I got it home my fiancé plugged the car up to the code reader. P129F “Manufacturer Control” were the results. After further researching, this is for the fuel pump/fuel pump control modular assembly. In January 2023, NHTSA released a notice for my exact vehicle for this very scenario I experienced. And as of June 6th, 2024 a class action lawsuit was filed against gmc for this issue as well. My vehicle is not able to be repaired due to 1) my vin not being included on the recall list and 2) all the parts that were in inventory are also deemed unsafe due to the lawsuit documents shared online and this has caused a nationwide back order per my conversation with 3 gmc/chevy dealerships. At this point my vehicle is unreliable and unsafe to transport myself or my children.

SERVICE BRAKES, ENGINE, POWER TRAIN
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.

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
Purchased Vehicle brand new- Beck & Masten Buick GM - Houston, TX [XXX] Performed rout maint regularly. Last oil change 1-5-2024 before catastrophic failure and complete engine seizure. Towed to Wiesner GMC [XXX] 1-12-2024: Mileage on car roughly 99K- had no issues no check engine light, no mechanical failure or indication that anything was running other than normal. No Start on [XXX] PM after work, tried to return next day with battery , changed out battery, engine still would not start, after new battery installed and we attempted to start, that is when engine started making loud shaking motion while attempting to start, windshield wipers came on randomly. First initial diagnostic: Found all oils & fluids in check, could not identify cause of failure, would have to break down and take apart. Had to authorize the tear down at a 1800.00 cost, 2/2/2024: Broke down engine, found that the crankshaft would move one way , but not other, removed the engine from transmission and now crankshaft moves freely. Now the AC comp is locked up (excessive play on magnet & clutch) , tech still unable to identify what caused the failure, they advised that they found traces of metal in oil pan, scored cylinder walls, starter shorted as well. They still could not indicate where these metal pieces came from, how or that it was due to owner negligence or manuf defects. Again this is a vehicle with 99K Miles and now we were looking at a 15K price tag for a new engine, turbo, AC, starter on a car that is worth 12K. This is absolutely insane. We reached out for Goodwill Discounts for some assistance since the dealership could not solidify a cause of failure, but GM decided to not warranty and stand behind their product. We were left with a rebuild option for 7500.00. which we had to do in order to get the car back. I am completely disappointed in GM as a company. This engine should have never failed at 99K.

The engine locked up due to oil leaking into it. This is a known issue with GM on these model cars but instead of issuing a recall they issued a special warranty that expired leaving consumers with these vehicles to be responsible for this repair which cost over $8,000.

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.

ENGINE
When starting the vehicle, I received a “reduced power” warning and then the check engine light came on. I was afraid to drive it to the service center, so It was towed. The repair center informed me that the timing chain failed and that engine will no longer start at all. I cannot afford to have the engine repaired no matter the cost because I’m still responsible for almost $6k of the loan for this vehicle, in addition to full coverage insurance required by the lender. Also, probably taxes as well because I now have a very expensive lawn ornament. Oh, and towing fees to deliver the ornament to the lawn. And then there’s the cost of finding transportation so I can actually work to throw money at all of those costs. Being buried financially because I put faith in this product is an injury and an expensive lesson.

ENGINE, UNKNOWN OR OTHER
The car very suddenly went into a reduced engine power mode, with check engine light and was immediately parked. Figuring I could turn the car off and turn it back on, however it sputtered turning off and shook violently before I was able to turn it off. It would then not turn back over, so I left it off and had a tow truck drive it to a GMC mechanic. The GMC mechanic was unable to diagnose an issue after days. I then had it towed to another local mechanic who stated the parts were "junk" and the engine needed to be replaced. Engine codes were related to the camshaft sensor and brake booster. It is my understanding the vacuum pump broke off into pieces, went into and destroyed my engine.

Vacuum pump is in the shop now being replaced for the 7th time in almost 6 years. The previous one was replaced in September 2023. You get no warning signs, then all of a sudden you can barely press down on the brake pedal. This started within the 1st year of purchase.

Was driving from home to my job in Novi, MI. While driving at 70 mph on [XXX] [XXX] miles west of Grand Rapids the motor suddenly stopped. There was never any warnings on dashboard instruments, no audio signs, and no physical signs this was about to happen. Had 16% remaining oil life before next oil change per computer. Dealership is telling me there is no oil in motor and it has suffered a catastrophic motor failure after timing jumped. This almost caused a major accident at highway speeds. Motor only has just over 77,000 miles on it. Of course it is out of warranty. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
