What owners wrote
Tl* the contact stated was employed by hertz rental cars. The contact stated that a 2020 toyota corolla caught on fire. Fire noticed 3-4 hours after vehicle was parked and driving out a parking lot. The fire department was contacted and extinghised the vehicle. A fire deprtment report was taken with file #111520199429275.
The battery tray (part number 74404-12560) which holds the vehicle's battery creates an unsafe condition. I noticed the battery tray is designed to fit only the panasonic battery that came with the vehicle. Thus, it is impossible to replace a discharged or defective panasonic battery with a standard bci group number battery which are readily available in retail stores.
