2013 GMC Terrain

I was driving my 2013 GMC Terrain to a friends house, I stopped at a stop light, when I picked up speed, the car stalled and wouldn't get up to speed. Eventually, it did pick up speed. I went to turn into her neighborhood and the same thing happened. Trying to get to the destination, I continued into the neighborhood. I stopped at a stop sign, and when I tried to accelerate, the car died. No indicator lights were engaged. I turned the car off and waited a minute or so and turned it back on. I got to her house, and charged my battery and drove home without issue. The next day, I went to have my battery checked and they alerted me to a horrible oil leak. I had the car towed to the dealership. The next day, the dealership told me that GMC would specifically have to look at the vehicle to diagnose. I had the car towed to my trusted mechanic and he told me the rear main oil seal blew out and found a service bulletin regarding this issue #14882. I made an appointment with the dealership only to find out that this isn't covered under the bulletin, because it expired in November of 2022, and it's not covered under my warranty. The warranty company stated, "if there isn't evidence of moisture in the PCV it would be covered, but since it's a known issue and a consistent problem with the vehicle, it's not covered." So, my only choice is to pay out of pocket for a defective part that will continue to break and cause the rear main oil seal to blow out of the car, potentially putting me and my 9 year old daughter at risk, because GMC isn't acknowledging this issue and recalling the faulty part that is the ROOT of the problem and has been widely reported. There is also a class action lawsuit that is currently open and ongoing (Case 2:22-cv-10785-MAG-JJCG) which is trying to hold GMC responsible for not recalling the part sooner - when they were made aware of it - putting thousands of consumers at risk. It's also fraudulent for this information to not be disclosed at point of sale.

While driving on the highway at speed limit 75mph, the vehicle (without warning ⚠️) suddenly went into (Reduced Power Engine Mode/ Service Stabilitrack) jerked and slowed down to 35mp almost causing a pile up as cars behind and next to me where still driving above 70mph. If not for my quick reaction to turn on emergency lights cars behind me would have hit me. Immediately after I got off the highway I drove the car (at 35mph as fast as it went) to my nearest Pepboys. Here the vehicle was serviced for nearly a month until the problem was fixed. The cost was almost $6500 GMC has failed to notify customers if this potential issue which not only risks the lives of the drivers and passengers of the 2013 Terrain but those driving alongside it. This is not a new issue as I found the testimonies of many other GMC owners tell a similar dangerous experience. Please help! I have detailed invoices of the repairs.

I've been having same issues Occurring since I Signed my purchase agreement. The constant rattle at about 1500 RPM, The oil leaves At such a rapid rate That I have to monitor it every day As to make sure the level doesn't go too low. I've only had the vehicle since September 2022 and here it is Halloween 2022 and I'm down over $2000 maintenance costs and maintenance costs trying to prevent catastrophic failure with the engine that I know is coming! OBDII code reads P0171

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?

Excessive oil consumption, on average this vehicle is burning off 2 or more quarts of oil over approximately 1,000 miles. The vehicle is also hard idling, jerky and lunging forward at a stop. The entire engine shakes until it sounds like it stalls out. The Check engine light turns on and off when it has been over 2500 miles after an oil change and when the gas gauge reads 1/4 of a tank or less. The diagnostic tool plug does not register anything; does not even turn the diagnostic tool on when plugged in. This vehicle has stalled while driving with no warning lights or indicators. I called GMC on 10/11/22 to inquiry about these issues the called me back on 10/12/22 and was told that they could not find a recall. I then mentioned the class action lawsuit and they said they found something. They then tried to tell me that recalls are ONLY VIN specific, which is a lie. I already got the recall notice but when I went to get it done they tried to tell me that I had to get services done with them for 6months before they would do the recall fix. And Now I have a car sitting in the shop that I can’t use because it needs a new engine.
