“Our 2016 Toyota Sienna spontaneously caught fire while parked in our driveway after returning from a short drive. After pulling into our driveway and shutting off the ignition, my wife smelled smoke as she was exiting the parked vehicle. This smoke intensified and quickly accelerated becoming an engine compartment fire. She called for me & then called 911; but in the brief moments it took me to grab a fire extinguisher, the fire further intensified with sizable flames erupting out from around the hood, front grill & underneath the vehicle. …”

The car was towed to hendrick Toyota of apex, nc and they told me that rodents chewed threw the wiring and it was not covered by my warranty. I have complained to both the dealership and to Toyota. I have had another Toyota parked in within the same proximity for over 15 years. I have never had rodent issues with it. I am concerned for the safety of my family.

NHTSA complaint #11173021, filed 2019-01, 10,000 miles“Dash lights and gauges all go out and head lamps go dim. Took it to dealer who could not do anything as the problem was not happening at that time. Started with about 8500 miles on car and I would say it happens about twice a week or more.”
NHTSA complaint #10944480, filed 2017-01, 8,500 miles“The dash board lights and all interior lights continue to go out with out warning. It requires stopping the van shutting it off and restarting it. The headlamp dim themselves and then brighten while driving. Took it to dealership twice now for issue. Dealer stated since problem was not occurring at that moment there is no test they could do. Service manager also stated that Toyota doesn't like the dealerships trying to guess at what maybe wrong. This is a major safety issue when driving at night.”
