My airbag indicator lit up and I was not involved in any accident or even a fender bender. After this the engine indicator lit up as well, I had to replace the battery, change spark plugs at the local Firestone. Now I have a problem with the theft indicator and the vehicle does not turn on. Several problems have come up since the airbag indicator lit up.

Bought my 2013 GMC Terrain SLT in 2017 from Carvana. I did not know there had been low oil issues or catalytic convertor issues that GM had put out a letter to get replaced in 2020. I always had to put oil in it. It just burnt right out. I also replaced 3 catalytic convertors. Fast forward to now 2023, I'm driving and my engine starts knocking loud. It has oil in it at this point. It finally died half way home 52 miles out. I had it towed home and then to a dealer. I find out from them that there was metal intermix with the oil and that this had a warranty for this issue. But... now my vehicle is 10 years old and over 120,000 miles. Now I can't get the warranty because it expired. that's crap! This should be a recall by now considering this has happened to numerous people with this year make and model. I can't spend $9,698 on a new 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?

Experienced two separate problems with the engine. The first is oil consumption. We have had to add oil almost every month for the past 2-3 years. The second is that the rear main seal blew after an extreme cold snap. While attempting to repair the vehicle we found metal shavings in the oil filter. The vehicle is no longer worth the cost of the repairs.

Sudden Excessive Oil Consumption, Engine Seized, Oil Pressure Alert Warning Failed to alert driver that the car was bone dry with no oil, and the Information Screen indicated that 25% Oil Life was Remaining, when the car was bone dry with no oil. FYI - GM paid for 50% on costs of a replaced repurposed engine. And yet there is/was no recall? They should have paid 100%

Vehicle began to hesitate and then became disabled. A large amount of oil was evident under the vehicle and continued to leak. It was apparent that the rear seal had blown out. Vehicle was towed to a GMC dealership and confirmed problem. Another mechanic informed us of a recall on these engines but this has yet to be confirmed with the dealership after nearly 3 weeks of it being there.

I have almost been in 3 accidents. My 2013 Terrain has stalled while driving..Cut off at lights. Engine reduced while driving and massive oil leak that gas caused timing chain and engine failure. I have read other complaints, and this is sad GMC has been allowed to get away with this. These engines are dangerous and need to be replaced before someone looses their life.

Vehicle stopped running due to timing chain issues at 106,000 miles. Dealer stated the 3.6L V6 is known to not last past 100k miles and they can't do anything. This needs to be a recall as it's a very prevalent problem.

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 -š ï¸) 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.
