“We have 2011 GMC Terrain. We bought it used so we have only had it a couple years. We noticed it seemed to be using a little more oil but then we were told to keep watch on it. My husband did. Then one day while I was driving it I thought I had heard a faint clicking noise. I said that car isn’t going anywhere until it’s fixed. Little did we know it wouldn’t ever start again. We didn’t know about a so call recall or not a recall. Still until we had to have it towed in to be fixed, I heard it mentioned. By then the car was repaired at our expense of $8000+. We are retired and don’t have or didn’t have money for that repair. The only reason we had a little money was because my husband got paid for back (lump sum) payment just a couple of days before this. We still owe on the car. Without it we only have an old 2001GMC SIERRA 1500. We live paycheck to paycheck. I called one of GMC’s phone numbers today and I was told if we didn’t have it done at a GMC FACILITY we get NO reimbursement. I cried. My husband is a real stickler when it comes to our vehicles and maintenance and logs and also keeps receipts.Please tell me there is some to help us.”
“I bought this vehicle and NHTSA made GM release an extended warranty on this vehicle for excessive loss of engine oil. In 2019 I had to take this vehicle and pay several thousand dollars for the pistons to be replaced in my engine because I was 1 year past the extended warranty. Now 3 years after spending thousands of dollars through a certified GM store I am having the same problem excessive loss of engine oil. I have zero leaks and I have to put oil in my engine every other day. If I do not by the end of the week I will have an empty engine.”
“SUV gets a slow down warning and it stops shuts off , it’s happened several times now I’m scared!!you wait few minutes it turns back on , mechanic said this a complain about this vehicle all the time , it has not been repaired I’m disabled with no money , I was on the highway and thank God I was on the slow lane if not I would have been killed by an eighteen wheeler. GMC is waiting for someone to die and probably address this issue”
