We have a 2013 Terrain that was repaired for excessive oil consumption (N192291100). Since that time, the vehicle has been experiencing catalytic converter/O2 sensor issues (N192287100), however GM says our vehicle doesn-€™t qualify for the converter/O2 special coverage adjustment because it-€™s not an affected VIN. I don-€™t understand how it would have undergone the initial SCA repairs, but then the new SCA doesn-€™t apply to it? The new one is a direct result of the first. The customer service reps I spoke with at GM couldn-€™t answer this question or provide me a way to go up the chain to get an answer. Any guidance would be appreciated. Thank you.

excessive oil consumption. This is a known problem with this car...you all know it is and GM should issue a recall.

Vehicle sputters on the highway sometimes shuts off at highway speed, when I turn my key off the car continues to run for 3-5 seconds. When I turn a corner vehicle sputters and tries to die sometimes does. When stopped at a stop sign vehicle will die. High pressure fuel pumps are known to do this and I have excess fuel in my oil.

I-€™ve been having a issue with my oil consumption and display messages about servicing the stabilitrak and traction control. I could be driving and suddenly my engine power is reduced asking with these two messages. I received a letter from GMC about the excessive oil consumption due to degraded catalytic converter and/or oxygen sensor. The one oxygen sensor was replaced before I received the letter. The letter states I should get the oil consumption diagnosed. I-€™ve went 4 times now and the oil dipstick smells like gas but the dealership is saying the special coverage has expired. My letter says otherwise. Why send a letter about a possible issue and then not help to fix it?

The engine in my 2013 GMC Terrain burns excessive amounts of oil. I'm constantly adding oil the the engine. Apparently the 'new' engine that was used in this vehicle is not working correctly. I don't have warrant left and I'm going to be stuck with a blown engine that is clearly the manufacturers error. I will never or will my family ever purchase another GMC vehicle. Pure junk!!!!

Vehicle burned a significant amount of oil. Parts were replaced under a lawsuit, but nothing was done to fix the problem. It is only a matter of time before it starts happening again.

Iin early 2020 I reached out to 2 different GMC dealerships in regard to the recalls that existed on my vehicle's engine and oil consumption. The vehicle was overconsuming oil (I would track the oil levels) and needed excessive oil changes. The first dealership said that my vehicle didn't qualify for the recall due to mileage when I just received the recall notice. Second dealership wouldn't even look at vehicle. A few months later the engine blew, spilling oil everywhere. The engine now needs a total engine replacement. Had the dealerships agreed to look at the oil consumption issues the vehicle was having and had knowledge of the GMC recalls on the vehicle, I wouldn't have an inoperable vehicle and needed to purchase a new vehicle due to the engine issues not being covered that were common knowledge on these make/model/year vehicles. I have tried to work with dealerships as well as my the financer of the vehicle, GMC needs to acknowledge this issue and contact me. Since the warranty ended on the vehicle the 1st year I owned it, I have put nearly $10,000 into faulty parts and replacements on the vehicle that weren't "covered". I would like this situation investigated due to the safety issues the engine caused that were refused to be looked at and now the negative financial aspect it has caused me.

11/9/2020 the engine light came on and the car randomly died so I had to have it towed to the dealership. They replaced both intake and cam sol valves, replaced the exhaust manifold, both HO2 sensors, heat shield, cat converter and high pressure fuel pump. This was all done at 121617 miles. Had no issues until 125,400 on 2/3/2021 the car randomly died while driving but I made it to work. On the way to get it checked out it made a loud noise and died resulting in being pulled out of the street and to the shop. They informed me that the timing chain came apart and the engine now needs to be replaced. It's 400 miles out of the extended warranty and the repairs in November totaled $3023.17 of which I had to pay $1,100 and now the car is inoperable and they want $7000 to install a new engine. I have found since this happened that this is a common problem that GM is aware of with the 4 cylinder engine. I kept up with oil changes and used synthetic oil

- Louisville, KY, USA

My Terrain is using motor oil excessively. After an oil change, I can drive 1000 miles then I start hearing a knocking noise on startup. I have to add motor oil at every fuel fill till my next oil change sometimes one quart and sometimes two or more. I have no leaks. The engine compartment is clean and dry and nothing is wet under the car ever.

- La Porte, IN, USA

GMC 2013 Terrain. Faulty engine make. Causing excessive oil consumption. Never alerted by any warning lights. Safety concern of engine possibly dying at any moment. GMC not willing to cover repair costs, even though there was a settlement reached, and they admitted over 40,000 customers not notified of engine issue. Please help!

My vehicle eats up oil. I just recently found out about the excessive oil consumption investigation. My check engine light has been coming on. Sometimes when I fill it with gas it goes off. A week ago it came on and then as I was driving down a busy street my traction control light came on, then a message on the display saying service stabilitrack and engine power is reduced. I couldn't go over 35mph. I took it to oreily the following morning and the code P0175 showed 'fuel system too rich'. I found a recall of an O2 sensor. I couldn't get into a GM shop for another week. Today they fixed the recall but told me the special coverage adjustment for the oil consumption was expired in 7/2020 for my vehicle. I chatted with GM online and they didn't answer all my questions. Even though I found the info on this here website about the investigation and the time limit and mileage on when I could get this problem fixed, GM would not explain in detail to clarify this info. It said 7 years and 6mos or 120K miles from when the vehicle was placed in service. They said third party sites like these aren't reliable. The shop mentioned I should just keep oil in it and that getting the pistons fixed would be $5K. My extended warranty does not cover and I was never notified about the investigation otherwise I would've never gotten the vehicle or at least got it fixed in said time limit.

The contact owns a 2013 GMC Terrain. The contact stated that the engine was consuming an excessive amount of engine oil. The contact stated that there was no warning light illuminated. The vehicle was not taken to a local dealer. The vehicle was not repaired. The manufacturer was informed of the failure. The manufacturer referred the contact to NHTSA to file a complaint. The failure mileage was approximately 133,223.

This vehicle is consuming oil at an excessive rate. This has caused other issues such as solenoids needing replacement as well as a timing chain. This seems to be a common issue among this year make and model. It is extremely dangerous to drive. I have to add oil in between oil changes and if the timing chain goes due to this, it can cause a major accident.

In January 2018 I had noticed at drive thrus that I could hear a knocking sound coming from my 2013 GMC terrian. One day I was driving home on the highway and when I got to the stop light I noticed the sound got very loud and once the light turned green the car would not go. After shutting it off an turning it back on, I was able to get it to a gas station, where oil was leaking everywhere. It was towed to a GMC dealer and they told me the timing chain had broke and I had to buy a brand new engine for a car that was 5 years old and had 106,000 miles. There was a recall that took over a year for me to be declined for which was the piston ring and now there is another one for the catalytic converter that poage is telling me I am denied for. How can there be 2 different recalls that effect the engine, but I do not qualify for either one of them. To spend $5307 on an engine for what is obviously a defect is insane.

I took my vechile for a recall, and they found it also had a cracked exhaust manifold. After researching on the internet I found that this is a very common problem with the GM 2.4 engine. Why hasn't a recall been issued for this problem, I would call this a serious safety issue as exhaust gasses can enter the vechile from the crack.

PCV valve froze causing rear crankshaft seal to fail. Engine needed to ne replaced. GM won't honor sb 14882. Car started to run sluggish in cold weather. Stalled and restarted. Parked in driveway overnight in 6 degree weather. Would not start. Oil qall over driveway.

- Macomb, MI, USA

My vehicle is using oil. I am adding 4-6 quarts between oil changes. It is not leaking out anywhere. I have taken it to the shop multiple times and they cannot find a leak. Sometimes the engine feels like it shakes when I crank the vehicle or when I shut the engine if. There seems to also be less power.
