SERVICE BRAKES, UNKNOWN OR OTHER
Driving home from our local town 4/15/2023, the brake pedal became to hard to push down. Check engine light came on as I got to my driveway, and that is 1 mile from the main road. My kids were scared to tears as was my girlfriend. Run a scan and dtc p0557. Come to find the vacuum pump on the top drivers side of motor is the part that is bad it broke inside the valve cover. Looking up the issue and find out it is a known problem and no recall. I have kept the parts and all receipts for the repairs, I have to do myself cause the repairs are way to much for me to pay out of pocket. This is a serious issue for this car and year and GMC needs to address the issue. Why has nothing been done yet??? I am making payments on this car with no warranty for the car so I'm stuck fixing the car. But GMC knows that this is a problem and does nothing?!? I remember when American cars were good cars what happened to that time ?? And what happened to company's being responsible for the product they put out to customers? Guess that time is gone, I won't buy another American car again, unless it's a old Detroit built car.

EXTERIOR LIGHTING
I was driving at nighttime and my head lights cut off.. they were in auto light mode. I read that gmc knows about some sort of issue with this but only covers repairs up to 150k miles. My car is 156k miles. There was no warning lights and no indication anything was wrong. Luckily I was the only care on my side of the highway and was able to slam on the brakes and come to a complete stop. I turned the car off and then turned the head lights to manual and they can back on. A few hours later when I got home, I let the car cool off and turned the headlight back to auto and turned the car on and the worked.

The car has been in the shop for the turbo being over boosted four times and is getting hot, so they put thermo tape on the part, and now what if the car catches on fire? This is an electrical issue that needs to be solved.

ENGINE
This vehicle is burning/losing oil. It is full, it will have a greasy substance on the dipstick and oil cap. Then after 1k-12k miles the oil is almost empty. I have had almost 5k in repairs at McLaughlin and they state nothing is wrong, yet I keep having the same issue. I went to key Auto mall and oil looked fine and now it is almost empty again. No oil all over the engine or on the ground. I don't want the engine to blow or have excessive oil changes. What is the remedy to fix this?

POWER TRAIN, ENGINE
Due to cold weather the PCV froze which caused pressure to build up in the vehicle’s crankcase which caused the rear main engine seal to pop out. Results in losing all engine oil without and warning driving down the highway. I was lucky enough to get off the highway but currently without a vehicle due to possible engine damage

ENGINE
During a long distance trip, the timing chain tensioner failed. There were no obvious signs of this condition when driving at highway speeds. No warning lights or reduced engine performance! After traveling over 200 miles, we stopped and discovered the engine was running very rough. We decided to stay overnight in a hotel and check the condition of the Terrain in the morning. The next day the car, started briefly and then stalled. It didn’t start again. We had the vehicle towed and the repair shop determined the the timing chain tensioner broke at some point on our trip. This caused the chain to come partially loose and that in turn “chewed up” the gear teeth. The metal fragments from the gears spread throughout the entire engine. This resulted in the engine to be declared unrepairable. If we hadn’t stopped, the engine could have creased up, and the almost assuredly would have resulted in a serious car accident. This was an expensive repair, approx $8000 and we incurred the cost of staying in a hotel for a week.

ELECTRICAL SYSTEM
The display screen of GPS/Radio is blackout combined intermittent control button illuminating light went off( include emergency, A/C control), backup camera stopped working, turning signal lost click sound. Safety concern: 1. Emergency and A/C control buttons lost illuminating light(Causing night driving difficult.). 2. AC vent the temperature control lost visual status cause distraction of normal driving. 3. Lost Backup camera function which is supposed to be an assisted safety feature. 4. Lost turning signal click sound which leads to missing alert of turning signal malfunction. 5. Complete audio loss create unsafe for long trip driving. 6. GM doesn't provide genuine replacement part. This problem started from 2018 till now. I've contacted GM with no meaningful resolution. I visited the dealer and the only thing they could do is replace non guaranteed refurbished head unit with hefty price. I did some research online and found there are a lot of same problems happened to this vehicle and similar models of GM. After driving this vehicle for several years without incurring any accident, I realized that the losses of the some vital control functions and safety alert are actually very serious concerns and should be addressed and resolved by GM.

SERVICE BRAKES
While driving at the speed limit on U.S. Interstate 83 in Pennsylvania, my 2019 GMC Terrain's braking system suddenly, without any warning, became severely limited. The brake pedal suddenly became very hard to press and the my ability to slow or stop the vehicle became very difficult, requiring a great deal of pressure to even slow the vehicle. The braking system worked perfectly until that moment. If I needed to stop quickly or if I did not have as much leg strength, it is highly likely the equipment failure would have directly resulted in a catastrophic crash. I struggled to get the vehicle safely off the road and stopped. I then had it taken to a certified auto mechanic shop. There, it was found the GM vacuum brake booster pump had inexplicably failed, making the "brake assist" function inoperable. The mechanic was surprised GM had a replacement pump in stock, as he said that is not the norm for other brands. A moment after pressing the brake for the first time as the incident began, a message appeared on the dash stating "Service Brake Assist." There was no pre-failure warning or symptoms. I was in the middle of a 300-mile road trip, having already completed about 220 miles that day, without any notable incident. The cost to replace and install the vacuum pump was about $640.

ENGINE, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
When I stop at the light my car shake and rocks, then the car goes into limp mode. Where the stabilitrack comes on and the engine goes into reduced mode. And I can't go over 30mps. When this happened on the freeway is the most dangerous and scary feeling ever. I've got So many new parts and put over 3,000 into the car and it still has this issue. I've been do several different mechanics and nobody can figure out what's wrong. Gm needs to look into this, it's so many forums going on for this issue.
