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.

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.

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.

2013 Terrain started shaking while my 16 year old daughter was driving it on the highway. She brought it home and parked it. Then it started leaking oil. On 2/15/21, we had the Terrain towed to the local GM dealership. Service manager, fred, said the rear main seal blew out caused from too much pressure due to frozen/plugged PCV. GM service bulletin 14882 describes this issue. On 2/19/21 at 3:15pm, fred stated on a recorded call with me and GM customer service that the Terrain's 'problems are exactly as described in the bulletin' but GM refuses to cover the cost to repair my 2013 Terrain with 99,500 miles. GM first agreed to pay $500 toward the cost of the repair, but has since reduced the amount to $200. This is a GM design flaw that causes engine damage. GM customers should not be responsible for paying for a repair caused by the negligence of the manufacturer.

2013 Terrain was in motion and stopped on an il highway in very cold February weather, check engine light came on. Towed to dealership, who states pvc crankcase issue. I investigated and found this issue is listed under bulletin 14882. Dealership and GM corporate line claim that the bulletin number does not apply to my vehicle and thus no special coverage available to cover repairs. Repairs are thousands of dollars for a new engine. Many other car owners have had this issue for years per google. The bulletin recognizes the safety risk, yet there appears to be no full on recall for inclusion of additional affected vehicles. Please help. This is unfair to consumers and hazardous to all wintery drivers. GMC should not be able to claim the bulletin is "VIN specific" when the issue arises due to cold weather--which we all know can occur in many places at any time. Thanks,

Driving home from work last night in my car and when I got to my neighborhood, I rolled down the window a tad for some fresh air, and then noticed a weird cranking sound coming from under the hood. I continued home cautiously, noticing at this point that when I would accelerate the car would shake some and the lights would flicker some. I had not noticed anything on the 25 mile drive to work that morning and most of the drive home until slowing down from highway to neighborhood road. When I got to my carport I parked my car and got out, noticing the smell of burning oil. I quickly looked underneath and saw oil spilling, and looked behind my car to see a huge line of oil from where I had come through the neighborhood to the carport. Faint blue smoke was also visible, at this point I shut my car off. There was never a single indication light of any sort at any point in time. I have full service records I have always maintained my car every 5000 miles or less, last time being barely 2 months before this incident, $150 service and full checkup. 30 minutes later I came back out to inspect and everywhere on the underside of my car was dripping oil on the ground, a good 7X3 foot area with drips everywhere and main pool near the front. After doing some research I have seen many many claims describing this exact problem with the same year and model as me, as little as 8 days ago posting about it. I have never had any recalls or notices of this problem but I see class action law suites over this oil consumption problem online, however I see also see articles saying how over 41,000 vins were excluded and people are having extreme problems with this situation. Non-personal info as a young man with this being my first major purchase, having maintained my car as required and having paid $10980 I am extremely upset being out of transportation due to mechanical flaw on piston design

I have been having oil consumption problems for the 11 months before the engine quit working as soon as I pulled out of a shopping center. I contacted GM to see if anything could be done. I had the car towed to a certified dealer to have them look at it and GM knew I had 124,000 mi on the engine. They still wanted me to bring it to them, for them to let me know they weren't going to help or pick up anything. I owe 9,000 on the car and thats what they want to charge me for a new engine. Tried going to another dealership to try to trade car in and they want me to pay almost 600 a month compared to my 225 now! no help where ever I go... before, I went to dealer and GM I tried to fix it by changing out alternator, spark plugs, new battery and Q new timing chain. When, we took top of engine off we found the fourth of July under the hood with roller bearing and rockers exploded everywhere along with the chain guard was wedged between gear and chain.

Oil was pouring out from the bottom of our 2013 GMC Terrain, "low oil pressure shut off engine" signal came on the dashboard. Terrain had to be towed to a local shop where they ran a diagnostic test. Diagnostic test came back with #19-na-021. We were informed about sb-10057977-8108, a recall from GM involving an oil leak from rear part of engine. We have also been informed that our VIN is ineligible and cannot be protected through the special coverage, but are requesting an investigation into the matter.

Driving my 2013 GMC terrein (2.4L) it was about 20 degrees out, a warning light came on that oil pressure is low "stop engine immediately. I pulled over at a gas station and as got out of the car I could see a oil spilling from below the engine. I had it towed to my mechanic and he said it had a a rear crankshaft seal oil leak. I had received an extended warranty bulletin 14882 which GMC recognize the issue. This special coverage covers the condition (2010-2013 GMC Terrain vehicles equipped with a 2.4L engine (laf, lea or luk) that have experienced high oil consumption may also experience a frozen and/or plugged PCV (positive crankcase ventilation) system during cold weather operation. This condition may increase crankcase pressure leading to a rear crankshaft seal oil leak) for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. My car is a 2013 GMC Terrain with 119,000 mile and should qualify for the extended warranty. I called the GMC customer service and I was told that my VIN doesn't qualify and the dealer is asking for $3500 for repairs. My mechanic did the repairs for $1500 but GMC will not reimburse.

My 2013 GMC Terrain died while I was driving down the road, it was found to have excessive oil consumption, none of the warning lights in the car came on not even the oil light to indicate low oil. The car had bad piston rings which was part of the cause. GM knew about this issue but didn't properly notify everyone involved. I knew nothing about this issue until it happened to me & later received a letter stating my car was inadvertently left out of the initial sca. The fact that these cars die while driving without any warning is extremely dangerous. I have children that were in the car when this happened we are lucky we didn't hit anyone and no one hit us. GM has been unwilling to help with any of this

I have called GM on numerous occasions regarding my engine failing while driving. Stalling in the middle of busy intersections. They opened at least 7 cases involving this same situation and knowing my fear of getting killed when this vehicle just shuts off while driving or just turning a corner or waiting at a stop light!! my heater did not work, my radio will freeze up and is non functioning sometimes..I'm afraid to drive with my grandchildren. As I write this my engine light came on again after a $1,000 repair of the timing chain. This happened while I was driving home from work at 1:30 in the morning on a country road and a sheriff deputy happened to be patrolling snd helped me by calling a towing service because my SUV would not start.. the deputy even got my manual out to see if he could figure out the problem.. when I called GM I was treated sooo disrespectfully by a girl that was assigned to my cases.. I do have receipts and the cases numbers and dates wrote down when I talked to GM.. I need a safe vehicle and I owe $19,000 still and now it's only worth $6,000... I'm a widow and only making ends meet.. this has been a scary struggle... please help!! thank you and god bless.🙏🏼

My vehicle began by stalling out when I was in reverse, while driving and would stall out when stopped at a traffic light or stop sign.

- Mantua, NJ, USA

I had complete engine failure because of the timing chain breaking twice for this issue. It has stranded me and hundreds of others on the side of the road while driving. There is a facebook page for it and hundreds of people say the same thing and how dangerous this is. Theres no warning, just dies on the road.
