Do not buy a GM car. They do not honor their warranties. (trying to make this review as least emotional as possible as we are devastated with a broken car) We bought a 2012 Chevy equinox which started experiencing engine problems and high oil consumption right around 80,000 miles. Soon after we started experiencing the problem we received a letter in the mail stating that if we had high oil consumption it was likely due to piston ring wear. GM stated in their letter that the piston rings would need to be replaced and the cost was covered by GM.
We performed the oil consumption test, which costed us money out of pocket, to find out that the Equinox was losing oil faster than normal and was most likely due to the piston ring problem. The dealership said GM would cover and to bring the vehicle in. We drop the car off at the dealership and were offered a rental. They didn’t have the kind of vehicle we needed but we accepted it anyway because a vehicle is better than no vehicle.
GM states that they needed to order the parts and would be coming from Michigan and LA so would take a couple days to get there. The parts get here after a while and then all of a sudden we get a call from the Midway Chevrolet on Bell Rd in Phoenix stating that the repair would not be covered due to engine sludge. They stated that the engine sludge was due to poor oil maintenance.
We looked up the most common causes of engine sludge (15 different websites) and oil maintenance was one of them but we also found that engine sludge can also be caused by worn piston rings, which is the exact reason for the letter GM sent. We told the dealership that we have our own oil maintenance records and had actually been getting all of our scheduled oil changes at the same dealership we bought the car at (we never missed one). The dealership then stated because the previous driver that didn’t get regular oil changes. We asked them how they knew that the lack of oil maintenance originally created the problem and not the piston ring problem. They didn’t have an answer for that.
They literally had the entire engine disassembled waiting for the parts from LA and Michigan and once they found out it wasn’t covered, told us that they wouldn’t put the new piston rings in, even though they are known to be bad. But, since they think it was lack of oil maintenance, they didn’t put the rings in and said they were putting the engine back together.
We can’t believe that GM would send us out on the road knowing we have bad piston rings. The bad piston rings were the whole reason for the letter. Why would you not repair something you know is a bad product? Regardless if there was engine sludge or not, GM should at least repair the piston rings as stated in their letter. We are still within the 7 years or 120,000 mile warranty and have plenty of time before it runs out. We will be posting this review everywhere we can find until this matter is resolved. Thank you for reading and hopefully you don’t end up in the same situation as us.
