Leased this vehicle in 4 cylinder, was promised 26/32 mpg city/highway. A BLATANT LIE FROM GMC! Veh gets 14-16 in town and can't get over 21 on the highway. GMC was contacted and set up a service check at the dealer. They came up with every phony excuse you could think of. Too much weight in the veh (which is empty) to the mileage gauge must be reset every time ( even though the On-Star app says the lifetiMe average mileage of both city/highway is 17). Avoid this car at all expense, it has no power and the mileage SUCKS. GMC will try to blame you for the crummy mileage if you complain. Searching for a lawyer to take on the big GMC Corp. Buy American, but not this American vehicle.
Talk about false advertising, the actual gas mileage is no where near the EPA. At 60k miles, the timing chain needed replaced, a loud rattling noise continued and the on board diagnostic light keeps turning off and on. Recently the car started to lose oil - 3 quarts - about 3,000 miles after the last oil change. Also, the car has been hesitating and then stalling while in drive, very dangerous! One of the mechanics told us the timing chain was a constant problem...why no recall? Also, there have been 3 recalls in the past 4 years. This is the 4th GMC vehicle we've owned and it will definitely be the last. We should have quit buying GMC after the first one....!
Must be one of the most dangerous cars on the road. It WILL stall and leave you stranded on highway, intersection, or a parking lot. And you won't be able to get it restarted. It mysteriously loses oil and will require expensive repairs to get it started again with no guarantee the stalling will stop. You get no warning. GMC won't acknowledge the problem even though service departments have the replace parts packaged and ready as though they know the engine should be recalled. Will be donating the car to the local fire department to do car burning training rather than reselling. I couldn't sleep knowing I sold the car to someone who could die in it.
I bought a gmc Terrain in 2011 and I thought it was going to be the best car I have ever purchased. Needless to says, I was wrong. This is the worst car I have ever purchased. I have had it for 3 years and it has done nothing but given me problems. I have taken this car to the shop at least 20 times in the last 3 years; and the dealers (Jim Hudson and Love Gmc) kept lying to me about the root cause of my problems. Honestly, they could not fix it. There is a major problem with the car randomly shutting off; and it only happens on the v4 model. Gmc needs to be taken to court; I will never buy another gmc again. I recommend you stay away!
We purchased a 4 cyl Terrain earlier this year. We like the vehicle overall but are very disappointed with the 21.6 MPG average over the first 9000 miles of driving. Most of the driving is on the freeway. Even on a long trip the best ever on a tank of gas was 23.5mpg. The main reason for us selecting the Terrain over other SUVs was the advertised mileage. We really feel we were scammed. I know that the EPA mileage to be questionable but to exaggerate the numbers by over 33% is almost criminal. Of course the salesman sold us on the 32 MPG but after talking to the service techs they tell me that there is no way that this vehicle can get more that 23 to 24 MPG. Of course now that we ha
