Consumer Description

In 10 degree weather after warming the car up and driving 15 miles began noticing exhaust smell but wasn't sure it was my car. No warning lights. Arrived at destination parking lot and car began to run rough and stall out and only then did engine light and oil pressure light come on. Strong exhaust/gas smell. Stranded in frigid weather with passenger in a wheelchair. Had car towed to dealer- pvc port plugged causing oil pressure to blow out rear main seal losing all oil causing damage to the engine and components. Warning lights did not come on until damage was done. Discovered it was a known issue with this engine and class action lawsuit has been filed. Was fortunate we were not on the road when this happened.
