Airbag System Malfunction

The primary concern is the Occupant Classification System (OCS) sensor, which can prevent the front passenger airbag from deploying in a crash. This is linked to two recalls. Symptoms include the 'Passenger Airbag OFF' light illuminating incorrectly. Estimated repair cost: $500 - $1,500.

Electrical System Issues

Complaints include frozen infotainment screens, sporadic sensor faults, and unexpected 12-volt battery drain. Some owners have reported vehicles catching fire due to electrical issues. Estimated repair cost: $200 - $1,000.

Issues include unexplained acceleration while brakes are applied, and some four-cylinder engines may consume excessive oil. Intermittent stalling or rough running has also been reported. Estimated repair cost: $500 - $3,000.

Fuel/Propulsion System Issues

Concerns include difficulty filling the gas tank (pump clicking off early), and for the RAV4 Prime, a 'Fuel Rail Pressure Sensor 'A' Signal Plausibility Failure' (P019064) often resolved by a software update. Estimated repair cost: $100 - $500.
