My husband was driving our vehicle on his way to work on [XXX] very early in the morning. He was on the highway going 70 mph. While driving he noticed a tire pressure monitoring system warning come up. Shortly after the vehicle went into reduced power mode. He was able to exit the highway and get the vehicle stopped. Upon stopping the vehicle died. Upon getting out of the vehicle he noticed a large oil leak on the ground and coating the underside of the vehicle. Had this incident happened during a busier traffic hour the sudden drastic slow in speed could have resulted in an accident. There was also oil left on the roadway that could be a hazard to other drivers. We had the vehicle towed to our mechanic. He confirmed that the engine had blown and would need replaced. He informed us that this vehicle has a known oil overconsumption issue. GM has settled on a class action lawsuit involving this make and model for the 2010 to 2013 model years. There is also a class action lawsuit currently in process out of Missouri against GM for the model years 2014 to 2017. I contacted GM and was told there was no active recall on my vehicle. I inquired about help getting the issue resolved and was told they were unable to help due to the vehicle not being diagnosed at a GM dealership. O have contacted GM dealerships and am having a hard time finding one that is willing to work with me on getting this issue resolved. This vehicle never warned of low oils or oil pressure. The engine did not make any kind of noise to indicate an issue. There was nothing indication anything was wrong with the vehicle until the vehicle went into low power mode and the engine was blown. A police report was not filed and insurance has not been contacted due to no accident being caused by the incident. The vehicle is still with my independent mechanic as we try to figure out how to cover the cost of this very costly repair.
