The timing chain snapped and caused the engine to seize on our 2016 GMC Terrain 2.4L SLC-1 SUV/Truck. Since this has occurred multiple times on the 2.4L engines in this model from 2012 - 2016, we believe that there should be a recall as this issue could cause a major accident if the timing chain snaps or breaks while traveling. It had 101000 miles on it when we bought it used from Klein Automotive, on April 12, 2024. We have only had it for 2 years and 4 months and kept it in good repair. We took it in for its oil change, brought it home, went to dinner 4 days after and the very next day it wouldn't start. We thought it was most likely the starter/solenoid, but the mechanic said those were both fine and that's when we got the bad news that the motor was shot because the timing chain broke which caused some engine rods to break. The GMC dealer, in Marinette, WI, we brought our used 2016 GMC Terrain to, told us that the timing chain stretched and broke the rods in the engine and there...

Unknown Or Other

For an undetermined amount of time- many months for certain, I have been unable to get the key removed from the ignition when the car is shut off and placed in the locked position. I am forced to start and shut off the car for multiple times before I am finally able to remove the key. There is no rhyme no reason as to why the key finally decides to come out. This is obviously caused no accidents, however, it has become a constant source of frustration as it happens constantly. I have taken it to the dealership, and other than charging me for their exam, they had no answers as to the problem or how to resolve it. That was an absolute waste of time, and certainly my money. I have also taken it to a couple of other places without any diagnosis of the problem. I am finally taking it to someone who I know to be reputable, and hope the diagnosis can be made, without tremendous expense on my part.

My cousin thought I had a trailing arm bushing was bad on the driver's side. The subframe holding the trailing arm rusted out completely. He was able to put his thumb through it with little pressure when trying to see if it can be fixed.

My 2016 GMC Terrain 2.4L Ecotec first stalled while idling at a red light in Raleigh, NC. I restarted it and it sounded different, so I drove it home. The next morning it would not start. The failure occurred at approximately 69,939 miles with no meaningful warning. The dealer’s diagnostic report states there were no current relevant codes and no relevant codes in history. The dealer documented major timing-system failure: timing chain tensioner failure, timing chain guide failure, a timing chain guide bolt pulled out of the cylinder head, aluminum contamination in the cylinder head/oiling system, and engine replacement recommended. The vehicle was found unsafe to operate. This vehicle regularly transported my family, including my children. If the stall/no-start failure had occurred at highway speed, while merging, or in heavier traffic, it could have created a serious crash risk. The oil was maintained outside the dealership network and had been serviced before failure. I also topp...

Windshield wiper mechanism broke while driving in heavy heavy rain near [XXX] . Extremely dangerous situation and almost resulted in a crash but I was able to make my way off of the interstate safely. Huge inconvenience because we had to wait out the rain!
