   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.

   According to our mechanic, our vehicle’s PCV system became clogged and it increased the pressure in our engine and caused the car’s rear main seal to rupture, leading to catastrophic oil loss, loss of power to the vehicle, and engine damage. In our case the entire engine needed to be replaced.

   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.

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…

    My 2015 Chevrolet Equinox has a cracked exhaust manifold, a known issue affecting many vehicles of this model. When using the heat or air conditioning, gas fumes enter the cabin, creating a serious risk of carbon monoxide exposure. I regularly transport my two young children in this vehicle, and we are forced to drive with the windows down in cold weather to reduce the risk. The vehicle also consumes oil and is still being financed. Despite the manufacturer being aware that…

    Timing chain tensioner lost tension and timing chain got so loose it would not turn the cams and catastrophic engine valve damage was done! This engine is notorious for this and there are class action lawsuits as a result but no recalls from GM as yet only TSB’s (Technician Service Bulletins). This is going to cost me thousands in repairs and I still owe $8500 on it. If this happens in traffic it could pose a serious safety risk in addition to the financial burden it is…
