Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving and the vehicle started overheating and smoking a lot. I pulled over and there was slushy fluid flowing from the car and I had to have it towed. I towed it to a nearby auto repair service professional for testing, and the test showed that the coolant was contaminated with transmission fluid and the transmission had coolant fluid in it. According to them, there was a malfunction of the coolant hose that allowed the coolant to mix with transmission fluid and as a result the car does not drive anymore. …”
NHTSA complaint #10679610, filed 2015-01, 73,621 miles“Traveling north on I-81 near bristol, va. Had cruise control on, driving in left lane when suddenly, the engine coughed and sputtered and I lost all acceleration. I was able to coast across three lanes of traffic and drift off the next exit, thank god! The dealer in bristol said it was a throttle problem and would be covered under the power train warranty. They called later to say they had to replace a power harness also, and it would be $990.00. When I finally got the car back the air conditioner was not working.”
