Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Dropped my car off for service at the dealership and they later called to say the engine had caught fire when they were test driving the car. An inspector from the insurors service bureau determined that a rodent infestation was the cause and that a nest had been built in the exhaust header. I have since seen several other owners reporting fires in the engine compartment and believe there might be a design defect that allows animals access to an internal location where engine heat ignites their nesting material.”
NHTSA complaint #10321624, filed 2010-03, 8,900 miles“There is a smell, like really dirty socks from the dash. It does not happen every time the car is used. To smell it you have to start the car and it is there. Sometimes the heater is on or the air. It also becomes less noticeable with time, up to 10 minutes. It is a very strong smell. I don't believe it is the catalytic converter, which has a different smell like rotten eggs. Because it goes away most the time I don't think is a dead mouse or something like that. It is not a dead animal smell. Help. You want to jump out of the car the first time you smell it. …”
