Electrical reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

My vehicle keeps leaking inside from the AC drip line and it's been cleared multiple times and it still keeps happening and it floods the whole bottom of the passenger side floorboard and becomes soaked through which can cause erosion, electrical issues, mold growth and other problems as well.

My vehicle is throwing the ABS light and slamming my breaks. I’ve taken it to Toyota, it’s not showing any codes so they can’t diagnosis it to fix the issue. It may go two weeks and drive fine, and then it does it again. Whether I’m going 10mph or 55mph, it will do this. Very scary and very unsafe.

My 2019 Toyota 4Runner was inhabited by a rat that chewed the wiring harness in at least 3 different areas. The damage occurred between 8pm and 7am. The vehicle started with lights on the dash illuminated. The car was out into drive and was jerking. Reverse had the same result. After inspecting under the hood of the car wires were seen chewed partially and a few completely severed. A rat was seen under the manifold cover. I used an air hose to evict it and had the car towed to dealership. The bill was just under $1000 to repair. I was warned it could have been worse ($6000) if harness needed changing. I was told “I was lucky”. After researching I discovered this is a problem because of soy based wiring. It’s an attractant for rodents.

Fire reported

I HAD BEEN DRIVING FOR TWO MINUTES ON A CITY ROAD GOING APPROXIMATELY 30 MPH, WHEN MY CAR SUDDENLY STALLED AND ALL THE INDICATOR LIGHTS CAME ON. THEN THE CAR STARTED ON ITS OWN AND I WAS ABLE TO TURN INTO A PARKING LOT. THEN THE CAR STALLED AGAIN AND I NOTICED SMOKE COMING OUT OF THE HOOD IN FRONT OF THE WINDSHIELD. I PUT IT IN PARK AND TOOK THE KEY OUT OF THE IGNITION. I GOT OUT OF THE CAR AND THE CAR RESTARTED AND STALLED ON ITS OWN A FEW MORE TIMES AFTER THAT. IT ALSO MADE A LOUD BEEPING SOUND THAT SOUNDED LIKE A CAR ALARM BUT WE DON'T HAVE AN ALARM INSTALLED. THE ENTIRE FRONT HALF OF VEHICLE WAS ANNIHILATED.
