“2012 TOYOTA 4RUNNER. CONSUMER WRITES IN REGARD TO TAKATA FRONT PASSENGER AIRBAG INFLATOR SAFETY RECALL. *LD THE CONSUMER REQUESTED TO HAVE A RECALL NOTICE MAILED TO A CURRENT ADDRESS. *JS”
Electrical system
6 reports
“THE BACKUP CAMERA DOES NOT WORK CONSISTENTLY. WHILE NOT MOVING AND THEN SHIFITING INTO REVERSE, THE SCREEN DOES NOT CHANGE OR CHANGES TO SOMETHING OTHER THAN THE CAMERA. IT USUALLY STOPS WORKING AFTER SEVERAL STOPS AND SHIFTS INTO REVERSE. SOMETIMES IT GOES 2 OR 3 DAYS WITHOUT DISPLAYING AND THEN STARTS WORKING AGAIN ANOTHER DAY.”
Service brakes
6 reports
“THE BRAKES OF THE VEHICLE SLIP. WHEN YOU ARE ON THE FREEWAY AND YOU NEED TO STOP FOR ACCIDENTS AND YOU BRAKE THE VEHICLE SLIPS AND ALMOST WANTS TO ROLE OVER. WHEN THE VEHICLE COMES TO COMPLETE STOP AFTER A FEW SECONDS IT MOVES FORWARD ALMOST 6 INCHES. THERE COULD BE SEVERAL REASONS WHY THIS COULD HAPPEN WITH ABS SYSTEMS, COULD BE HYDRAULICS, COULD BE THE SENSORS, IT COULD BE PULSATION. DIAGNOSIS FOR THIS REQUIRES PRECISION NOT A SIMPLE TEST DRIVE. THE DEALERSHIP SAYS ITS NORMAL AND THAT'S HOW LIMITED SLIP DIFFERENTIAL WORKS BUT IT SLIPS OFTEN AND ON EVEN ROADS. THE DEALERSHIP WANTS ME TO DUPLICATE THE PROBLEM FOR THEM AND I WON'T WANT TO GET ON THE HIGHWAY AT FREEWAY SPEEDS TO SHOW THEM HOW THE BRAKES SLIP. ITS A SAFETY CONCERN. I CALLED THE MANUFACTURER SINCE I AM STILL UNDER WARRANTY AND THEY SAY THEY WONT DO ANYTHING. BOTTOM LINE THE BRAKES ARE NOT SAFE AND I AM WORRIED ABOUT A ROLL OVER OR A SERIOUS ACCIDENT. *TR”
Steering
5 reports
“Consistent steering wheel shake between 60-65 mph. This is a very well known issue on the 2010-2024 4Runners and it drives me and many others crazy, and feels unsafe to drive with. Will happen almost anytime I’m on the highway. My vehicle only has 48k miles. This needs to be addressed.”
Engine

“Vehicle radiator light came on, shortly thereafter (5-10 min) vehicle overheated. Waited for vehicle to cool down, then drove home. The following day drove the vehicle to dealership. After an inspection the dealer stated the heads are cracked and needed to be replaced. When I asked how this could happen to a car that is regularly serviced with only 90k miles his response was "the original heads were made of weaker metal, the replacement ones are upgraded. We haven't had any come-backs on the ones we've replaced". I then asked, well how many vehicles has this impacted? Sounds like this should be covered under a recall? His response "We've had quite a few in the past month or so, seems to be happening when vehicles get to the 70-80k range." Sounds to me like Mazda knew the heads were made from inferior products which is why they upgraded the part on newer models.”

“The contact owns a 2012 Toyota 4Runner. The contact stated while driving 50 MPH, the vehicle lost motive power and stalled. There was no warning light illuminated. The Police Department called and arranged for the vehicle to be towed to an authorized dealer to be diagnosed. The contact was informed that the fuel pump had disintegrated and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not under recall for the failure. No further assistance was provided. The failure mileage was approximately 87,000.”
