Almost a month after my oil change my engine started making noise and cutting off. When I took it to get checked, they said that my oil was gone and my engine is failing. Now my car is just sitting at the dealership, because the price is gonna be to high. Is their a recall for my 2011 g. M. C Terrain.
Excessive oil consumption. I purchased a 2011 Terrain not knowing there was an issue with the excessive oil consumption. There is no warning light just started tapping in the engine. Noticed a knocking/rattling in engine while accelerating at slow speeds, on board computer stated remaining oil live was over 51%, however no oil registered on dipstick. Add oil and noise stopped. I only discovered because I started to hear a stranger noise when I was stopped with the car running.
As I read through all the complaints I do not understand why there are not more recalls on this vehicle. I love the car itself but after only having the car for 15 months the motor completely failed with no warning. Our Terrain has the 3. 0 engine but there is an extension of warranty on the 2. 4 engine. However the complaints on the 2. 4 motor mirrors what happened to us. We had fuel injectors replaced a few months ago and oil changed at that time. The night the engine died it had made some strange noises but no hesitation and no warning lights. Not even a check engine light. My husband checked the oil and it was low. There is no way it could have been low. He added some because that is what we are conditioned to do but it never would register on the dipstick. We drove 1/2 mile and the without warning; no noises or warning lights the car died at a busy intersection. Thankfully my husband was able to push me in the car to safety but the car never restarted. We had it towed to the dealer we purchased it from and they said the motor seized up but are unable to tell us why unless we pay for them to take the motor apart. They are unable to find any error codes. They are telling us we need a new motor costing $7400 to purchase and put in. The car is out of warranty. We only bought the vehicle 15 months ago so we haven't had it long; we bought it used. Makes no sense but does sound like the stories on the 2. 4 motors. When is someone going to take notice that there is a problem with these GMC motors whether it is the 2. 4 or the 3. 0 engines. Does it take someone to get killed before GMC admits there is a problem??????.
We purchased the GMC Terrain with the 4 cylinder engine for the gas mileage of 32 mpg, after getting only 26 mpg we called GMC and took the Terrain in for service. Also filed complaint with GMC. Was told their was nothing they could do. The engine makes noises and runs rough and stalls at times mostly in the mornings. After service now we get only 25 mpg.
