Typical engine symptoms owners report

Vehicles caught fire under the hood hours after being parked and shut off, with flames or smoke coming from the engine bay and no clear ignition source found.
Some owners linked engine-bay fires to the PCV valve heater or oil filter housing gasket leaking onto the alternator, which then overheated and melted components.
One driver reported sudden loss of acceleration and power at low speed, causing the car to roll backward into property.
A new vehicle reportedly suffered engine failure within days of purchase after a spark plug defect burned out a coil and damaged a valve.
Electrical connections were reported to stay active even with the car off, which one owner tied to a garage fire that started under the hood.
