Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Engine light came on. I was told by the first dealership that the coolant was mixing with the engine oil. There was also a vehicle at the shop there for the same issue. after doing some research online, it appears that this is a bigger issue. I bought the car at 20,000 miles and this began happening around 52000 miles. Given the low mileage, this is something that should not be happening to a newer car.”
