Electrical system
24 reports
“My gear shift became difficult to shift. As I was driving it, when I physically shifted to the Drive position, the display didn't confirm "D", but I could drive. As I was driving, the car shifted to Neutral without me shifting, but did not show "N" on the display. My car stopped accelerating and revved higher. This occurred as I was driving on the road around 45 mph. I could not tell on the display that I was not in Drive. I pulled over safely luckily. I Continued to try to get it to drive to get it to a dealership to look at. They reported it was PRNDL switch issue. TECH FOUND INTERNAL CORROSION IN TRANSMISSION RANGE SENSOR CREATING A PHYSICAL RESISTANCE IN SENSOR WHICH PREVENTED VEHICLE FROM PROPERLY INDICATING GEAR. TECH REPLACED TRANSMISSION RANGE SENSOR, ADJUSTED SENSORWITH TECHSTREAM DATA LIST, AND PERFORMED HEALTH CHECK This is not the first they have seen either. This would appear to be a common safety issue to drivers. I also had a difficult time confirming the car was in the Park "P" position. I believe this issue could have potentially affected the vehicle's ability to engage in park and stay in park, much like the issue with getting into Drive and staying in Drive.”

“GREATLY REDUCED SAFETY IN FRONTAL IMPACT DURING AN ACCIDENT DUE TO CORRODED FRAME COMPONENTS CAUSED BY FACTORY INSTALLED FOAM PIECES THAT RETAIN RAIN WATER. THIS PROBLEM HAS BEEN NOTICED, PERSONALLY BY ME, ON MULTIPLE TOYOTA 4RUNNERS OF MODEL YEARS 2014-2016 SO FAR. THE CORROSION DAMAGE ON MY VEHICLE MAKES ME FEEL UNSAFE WHILE DRIVING TO WORK AND NOT ADEQUATE TO BE TOWED FROM THE FRONT HOOKS INCASE OF AN EMERGENCY. I TRIED TO BRING THIS CONCERN TO A LOCAL TOYOTA SERVICE DEPARTMENT AND THAT WAS OF NO HELP. IMAGES ARE ATTACHED BELOW THAT SHOW HOW THE FACTORY FOAM PIECES SURROUNDING THE RADIATOR AND ITS "SHROUD" HAVE CAUSED A HIGHLY CONCERNING AMOUNT OF RUST ON THE VEHICLE'S BUMPER AND FRAME SUPPORT MEMBERS. THESE FOAM PIECES GET WET FROM DRIVING IN THE RAIN AND RETAIN THE WATER. THIS OVERTIME CAUSED THE RUST SHOWN BELOW. THE NEWER MODEL VEHICLES SEEM TO HAVE A RUBBER FLAP RATHER THAN FOAM WHICH WOULD PREVENT WATER DAMAGE ON THE FRAME MEMBERS. MAHALOS ## VIN PASSED ## TOYOTA 2014 ##”

“I had a collision and rear ended a truck. My front left bumper was completely damaged. My chest hit the steering wheel. My airbags did not deploy.”
Steering
7 reports
“The steering became almost unresponsive and I could not turn the steering wheel while driving. I brought it to a repair shop and they said the intermediate steering shaft and u-joints were rotted out and rusted to where it seized up. The vehicle only has 55k miles on it and I don’t live by the ocean. The parts were repaired by a shop and steering feels like new again. Had this seized up on the highway or at high speeds it could have been very bad. There were no warning lamps or issues with steering before”

“I am reporting what I believe is a design defect involving the Secondary Air Injection (SAI) System on my 2014 Toyota 4Runner. My vehicle illuminated the Check Engine Light and stored Diagnostic Trouble Code P2440 (Secondary Air Injection System Switching Valve Stuck Open). During my inspection, I found that the factory-installed foam air pump filter had completely deteriorated and was missing. The filter appears to have disintegrated over time rather than being removed during maintenance. The filter is intended to prevent contaminants from entering the Secondary Air Injection pump and switching valves. Once it deteriorates, debris can enter the system, potentially contaminating the switching valve and causing the P2440 fault. This failure caused my vehicle to enter reduced-power ("limp") mode, resulting in a significant loss of engine power and acceleration. This created a safety hazard because the vehicle could not accelerate normally while driving, increasing the risk when merging into traffic, crossing intersections, or traveling at highway speeds. Toyota has discontinued the original replacement foam filter, preventing owners from restoring the system with…”
Fuel/propulsion system
6 reports
“I notice my gas wasn't lasting long. One day I was pumping gas and noticed that underneath my 4-runner gas was pouring out from the top of my fuel tank. Took it to the dealership and they repaired the charcoal canister, canister assembly and purge valve assembly. Cost me $953.48 with parts and labor. Very dangerous due to it could have started a fire while driving.”
