ENGINE
Engine died in the middle of the freeway when driving, creating hazardous condition. It was later found out there was no oil. Oil was changed less than 2000 miles prior by GM dealer, there was no leak on the garage floor and there was no warning that oil was low and the exhaust did not look any different. There was no way to tell the engine was burning oil. The engine had barely 110k miles.

EXTERIOR LIGHTING
I took the car in for a recall regarding the headlights. The recall number is N222363740. The dealer placed a sticker. On the headlights, which now makes it hard to see at night this is my wife’s commuter car to work at the hospital. We live in a very rural area where the 2 lane roads are remote and very dark.my wife works from 7:00 am to 7:30 pm but with her commute she leaves at 5;30 am and returns home around 9:00 pm . This includes every single shift she works, so the bottom line is she leaves at dark and gets home at dark, needing her headlights to work and home every trip. ever since they applied the sticker to the headlights, she’s having a much harder time seeing the road which is making it dangerous especially in winter weather. Since she travels by Two lane very dark back country roads. I am asking for a different remedy for the headlight situation, other than the stickers on the headlights that are actually making it harder to see. I’m afraid she’s going to get in a car accident rather it be with a vehicle or the many deer. We have run across the roads out here by not being able to see. I feel this is very time sensitive and would really appreciate a response back as soon as possible. Thank you very much.

ENGINE, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
My engine Burns a very large amount of oil rapidly. I have to replace oil in the engine at least twice a week. I went to the Automotive Service Center and they indicated that my timing chain need to be readjusted and that the engine itself between the year of 2010 and 2017 on gmc terrains have major problems/ defects in with the engine. I was driving on the highway and the car slowed down I barely could get any acceleration. I then had to get off of the expressway to avoid collisions. I took my car to the shop several other times for automatic brake system problems and stability track problems. I had censors replacedvand stability track problens. They wrre fixed but the automotive technicians indicated they the oroblems will happen again. Soon after that my engine was low of oil again within the matter of two or three days. The problem (massive oil consumption) continues to happen. I have investigated the problem and I found that there were engine class action lawsuit on the GMC 2014 Terrain because of the engine problems. I need to know how I can get my problems with the engine in particular resolved so that I can move forward and not worry about being involved in a motor vehicle accident when I drive to work each day.

ENGINE, POWER TRAIN
The engine is burning oil at a rate of about a quart every 2k miles. The check engine light came on recently and very shortly after a reduced power warning came on and made the vehicle difficult to drive. Which was not safe on a major road. It had to be towed to my mechanic and he mentioned to me that the engines in this vehicle are known to be problems. The pistons have an issue that burns oil in excess he said. I looked this up and found a class action settlement was just awarded to people in 3 states. However not mine.

SERVICE BRAKES, ENGINE
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...

ENGINE, POWER TRAIN, VEHICLE SPEED CONTROL
First off before I got the car it had gone through a tune up. About a couple months after I got the car little things started to happen it would rock back and forth while idling I thought it was kind of an indicator that it needed oil but the percentage was still at a decent range and telling me it didn't need oil plus I hadent driven it 3000-5000 miles. Then engine light came on had it inspected codes ran came back telling me something about Throttle body So I purchased a whole new throttle body in Prosser at dealership costing me some booko buks and swapped it out when I got back home I then took it for test drive along with my 4 kids in the vehicle with me and then a little ways about 20 mins driving engine power reduced light came on along with stabilitrak and eventually lost power I was stranded in the middle of summer in the middle of nowhere with my kids windows rolled down ppl drove by and asked if I needed help and eventually came back with jumper cables tried to jump me but the car wouldn't budge I then left the car there overnight and took battery out to have it inspected the next day IT WAS FRIED (over 4 yrs old) so I had to purchase a new one costing me roughly 150 buks then took it back to where my car was stranded put it in and alarm went off and I clicked the button on key ring stuck it in ignition shit the door behind me locking keys in car while vehicle was still running and had to bust a window out to get to em. Got into car drove off made it back to my apt left it running outside while I went inside to get some stuff before I THOUGHT the problem was solved it shut off again.....I then had to replace the alternator costing me another pretty penny....about a couple weeks later I was starting a new job at a assisted living facility and arrived 10 mins early shit car off a noticed smoke coming from under hood I was confused because where the smoke was coming from couldn't have been it overheating I popped the hood and my car was on fire!!!!

I still have more to add to my other complaint. The fire started with alternator apparently there were crossed wires took alternator back to Orielys where I got it warrented out fixed the expanded wiring and replaced a hose and other things damaged by the little fire. Then after that things kept getting worse. Then it was spark plugs that were rusted that I replaced eventually I complained back to the dealership I got the car from and they agreed to help repair it after a posting by me on fb that I wasent a happy customer basically and that I literally had a sitting duck. Turns out the timing chain needed to be replaced and other little things. I've replaced O2 sensors camshaft sensors gaskets in catalytic converter had it inspected thinking it was a clogged exhaust the excessive oil usage was insane I would be going through 5quarts twice a month! I'm just tryna have a DECENT WORKING VEHICLE for my kids and I. I literally can't keep a job because I DONT HAVE RELIABLE transportation....I've put sooooo much money into this vehicle and now I might have a blown gasket!!! And that's because I haven't even been driving the vehicle. I got the car on Jan 7th 2021 with 129,043 miles on it as of today it has a total of 164,627 miles on it meaning in between the two years that I've owned the vehicle I have only put a total of 35,584 miles on it.....for it to have this many problems for so little mileage is INSANE!!! my kids were in the car with me today when the car started smoking like crazy from under hood and exhaust I pulled over turned the car off and took my baby off car seat in all and got away from vehicle thinking it was on fire again. I popped the hood and notice it was coming from under manifold.....meaning its probly a blown gasket after I just replaced the camshaft sensor AGAIN......it's ridiculous all the stuff thats going wrong with this vehicle with so little mileage that's been put on it.

As i went to drive my terrain we bought back in June or July. But for the absolute first time we needed to use the defrost/defogger button last week on OCTOBER 20, 2022 and it wouldn't work. No lights came on to say it was defaulty. It also started to make our radio screen flicker when i tried to turn defrost on and it's continuously flickering and defrost doesn't engage on front windshield at all won't even melt snow or help defog when it's been raining or it's cold out. I almost wrecked my terrain due to this problem. Now on my instrument panel says camshaft/crankshaft sensor says service stabilitrack and something about my AWD System. All these happened within a week from trying to use my defrost. Also my instrument panel where it shows how fast i go flickers and it flickers on the RPM side as well. Noone has touched or looked it over since i have owned my 2010 terrain. Everything was just fine up till i pushed my defrost button and then all the other stuff happened

ENGINE
We purchased the car in September of 2021, had the oil changed about two months after we bought it, no mention of any issues. In January, half of dashboard lights and the digital speedometer went out. The check engine light came on. We took the car to a mechanic and there was no oil registering on the dipstick. They put several quarts of oil in, the check engine light went off, and the dashboard lights/digital speedometer returned. If the engine had failed it could have caused a serious, possibly fatal accident with other vehicles. Upon research, GMC had issued a special coverage for excessive oil consumption. This appears to be the problem with our vehicle as we need to add oil at least once a week, and the car is not driven over 500 miles in a month. Because the special coverage expired even before we purchased the car, GMC will do nothing to honor the warranty. So what happens to all of the new GMC owners that are inheriting a serious problem they had no control over having remedied?
