What owners describe

Air bags

Owners describe air bags that sometimes fail to deploy during collisions, or that deploy unexpectedly during normal driving or minor impacts, sometimes causing injury. Several also mention delays getting recall-related parts replaced at dealers.

Warning signs:
Some owners report no warning lamps or unusual vehicle behavior before the airbags deployed unexpectedly or failed to deploy during a crash.
What shops did:
A few owners contacted dealers about a Takata-related recall notice but were told replacement parts were not yet available.

“The Roll Over Side Curtain Airbags deployed and hit my head. Both sides deployed.”

“The passenger side curtain air bag partially deployed. When this occurred it blew the door ajar.”

Electrical

Many owners report rodents chewing through wiring harnesses, causing warning lights, rough running, or loss of electrical function, often requiring costly harness replacement. Others separately describe door lock actuators failing over time, along with a few reports of burning smells or dashboard power loss.

Warning signs:
Owners noticed warning lights, engine shaking or hesitating, transmission acting oddly, doors not locking, burning smells, or accessories cutting out.
What shops did:
Dealers replaced chewed wiring harnesses (sometimes out of pocket), replaced or quoted door lock actuators, or in some cases found no clear cause.
Mileage:
most between 10,000 and 35,000 miles, among 11 complaints that give it

“The car was running on five cylinders. We managed to get it to a toyota dealer who told us of bite marks and droppings.”

“my radio, usb ports blower motor and dash cluster power went out”
