Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Vehicle was in motion on a city street on 12/24/18 when the entire system (engine, electrical etc.) completely quit. I was near a stop light, so I stopped and restarted the engine and resumed travel. On 12//27/18 I was in motion in a parking lot and the entire system failed again. At this time no systems were operable including lighting and the vehicle did not immediately restart with the ignition key. After approximately 5 minutes the vehicle responded to the ignition key and restarted. I took the vehicle to a Toyota dealership and they did a diagnostics test. …”

“The vehicle is hard to stop and the brakes are spongy, ive driven a few 4runners and they are all like that and its dangerous. You have to push the pedal to the floor. The engine makes a horrible ticking sound when idling and sounds like the engine is going to blow up”

“My exhaust pipe rusted apart after the muffler causing the hot exhaust to expel upward and melt a rubber grommet on the floor. Then it proceeded to shoot into cargo area, melting the carpet backing and Styrofoam pad and insulation under the cargo area carpeting. This happened on an 11 hour road trip with the cargo area full of vacation stuff. I'm concerned about this being a potential fire and carbon monoxide issue.”

“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. …”

“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. …”
