Vehicle started leaking oil with no indicator. Didn't realize it for at least a few days. When I smelled a burned oil smell took it to the repair shop. Was told my oil gasket blew and the engine is about shot. I also only a month earlier replaced the battery. These vehicles apparently have known battery, oil and engine issues that were known since 2010. The following class action lawsuit in Missouri is pending: [XXX], on behalf of herself and all others similarly situated, Plaintiff, v. GENERAL MOTORS LLC, Defendant. _____________________________________ Our vehicle is not even at 100,000 miles! This will cost thousands of dollars to fix or we will need to purchase a new vehicle which we didn't plan on for a few years at least! This has been devastating. Please help.

Vehicle shut down and turned off while being operated. No warning lights were on at any point before the incident. I was driving down the road and without warning, it just turned off. My safety as well as the safety of the drivers on the road around me were compromised by this sudden failure as the vehicle was in motion when the incident occurred and I was unable to properly operate the vehicle. When I tried to re-start the vehicle the engine would not turn over and several warning lights were suddenly on. Vehicle was towed to dealership and the service department said the timing chain jumped and the engine needs to be replaced. Multiple complaints have been made against GM for the faulty 2.4L Ecoboost Engine that causes excessive oil consumption with no appropriate monitoring or warning system in place leading to timing chain issues/failure that destroys the engine without warning, often while the vehicle is being operated. No recall has been made and no warning is given to customers who purchase vehicles with these engines. I have owned this vehicle less than a year and the repair invoice I was given quotes over $10,000.

There's an oil consumption issue that requires you to constantly refill the engine with oil between oil changes. It's so bad that it causes buildup and eventually interferes with the timing. Causing significant, unacceptable repairs! Now I'm forking out money for a constant issue that shouldn't exist! My car cut off in traffic! That's a major safety issue! I will provide costs of repair when I get the final estimate! My timing chain, tensioner and pistons may need to be replaced because of this issue!

Bought car in 2021 and a few months later car started turning off while driving. Check engine light came on..replaced sensors and all was good. Fast forward to a week ago...scheduled an oil change like I always do...check engine light came on and engine started rattling. Stopped driving immediately. Checked oil and there was none. Added 3 quarts. Took to garage to have them take a look at it. He did the oil change but doesn't handle engine repairs and believes it is my timing belt. The vehicle only has about 65,000 miles on it and is a 2014. Common occurance apparently with this vehicle that needs to be addressed.

Other years of this vehicle have recalls for the catalytic converter. My check engine came on and it said it could be that or the O2 sensors. O2 sensors have been replaced and the check engine light is back on.

Timing chain malfunction that burned through oil causing the engine to seize. No engine light indicators were displayed in regards to this issue. The issue escalated quickly with signs showing only 2 days before the engine finally seized & leaking oil into engine bay. It is also noted that the engine oil has had many reported leaks into fuel tanks & other areas of the car.

My check engine light would come on, the oil dipstick would be dry and multiple misfire codes happened. This went on multiple times because of oil consumption. I would pull over and call AAA to tow my car. Driving while the oil is low is damaging parts in my car, causing loss of power and can cause a fire. I have to check my oil dipstick every week to make sure it has enough oil before I drive. I'm adding oil multiple times before an oil change is needed. The oil consumption was confirmed by a GMC dealer and documented. GMC dealer inspected my car. The oil consumption started 08/10/21 and was documented again on 11/19/21 with GMC Tech stating what's wrong. Oil consumption is going on with multiple GMC vehicles and GMC has not done a recall and they absolutely should have a recall.

On December 26, 2022, my son and I were on our way to Indianapolis, Indiana from Anderson, Indiana. When we were about to the end of going through Ingalls, I noticed that my check engine light went off. I pulled over within 3 to 5 miles within notification of my engine light going off at a gas station. I turned off my Terrain, so my son could look under the hood to see if anything was amiss and I turned my Terrain back on hoping that the check engine light would go off. It didn't and the engine sounded normal. We proceeded to go on to Indianapolis driving on. Everything was fine until right before we reached 30th and German Church Rd. I started hearing what I thought was a clicking/ticking sound, so I turned off my radio to confirm it. As I turned down the radio to confirm the sound, my dashboard let me know that my engine was losing power and a stabilitrack warning. I immediately pulled over to check to see if my serpentine belt broke. It hadn't. My oil read at 29% and no other lights were on besides the check engine light. NOTHING letting me know that I was losing oil. A friend of mine came to listen to it and thought maybe my alternator was going out. I attempted to drive it to a garage that was maybe at most 2 miles away. It started right back up but lost power again less than a block away from where I stopped. I pulled it into a parking lot to get it off the street. I had it towed from the parking lot to a garage to have it looked at and I was shocked to find out that I was out of oil even though the dash read 29% before needing another oil change. NO OTHER WARNING that I was losing oil. The mechanic notified me to let me know that I had a blown engine. I'm furious with GMC right now because I had overheard approximately a couple months ago while getting my oil changed that GMC engines were going out left and right and now it's happened. to me. I don't even want to think about what could have happened to my son and I if on the interstate being very short notice

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.

The contact was informed that the timing chain, pistons, and pistons rings needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case. The approximate failure mileage was 68,500.
