“I purchased this Vehicle in February of 2023, I had a problem shortly after with the oil always being low. I was adding oil to it all the time. 7 months later the engine blew. This is a very faulty problem with this engine that I am NOW finding out. This problem needs to be addressed and fixed. Now I am stuck with a vehicle that I still owe money on that will cost me 6 to 9 thousand to replace the engine.”
