Rear main seal has blown three times since I purchased my vehicle from Carvana. I’ve pulled the engine out myself as I cannot afford another $3,500 at the shop. I’m a single income household that makes too much for financial assistance. The Chevy Equinox was the only vehicle in our price range. That was prior to the seal blowing, again.

Noticed knocking in the engine and excessive oil usage. I keep my vehicle maintained. I went and had the values and seals replaced around engine for oil. Not even two to three weeks later knocking again. Took it back and engine is burning oil. Read about this make and model having defective pistons and rings causing oil to burn excessively. This has cost me thousands of dollars and it's still not fixed.

My daughter, the driver of this vehicle, noticed a noise. The check engine light came on. Over a short period, the noise from the engine progressively worsened. We brought the car to a certified mechanic. The mechanic's initial determination was that the engine would need to be replaced. It was determined that the engine was faulty, failing due to oil leakage that led to excessive oil consumption. As we were not ready to make that kind of financial commitment, we asked him if there was another option. We were instructed to check the oil frequently. We did so over the next couple of months, but the problem continued and worsened. As my daughter was driving, the engine would make a noise and lose power. Eventually, the vehicle started shaking and would shut down when stopped at red lights and stop signs, requiring the engine to be restarted each time. We then brought it back to the mechanic, and the engine was replaced with a new one.
