   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 the factory-designed component. Numerous other owners have reported similar failures involving deteriorated or missing foam filters, P2440/P2442 diagnostic codes, and costly Secondary Air Injection System repairs. I respectfully request that NHTSA investigate whether deterioration of this factory foam filter is a design or material defect that allows contamination of the Secondary Air Injection System and can lead to limp mode and reduced engine performance. If confirmed, Toyota should provide an appropriate remedy, such as redesigned components or an extended warranty for affected vehicles. This failure appears to result from deterioration of an original factory component rather than improper maintenance or normal wear and presents a potential safety concern for other Toyota 4Runner owners.

   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 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.

    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.

    Three of the four locks do not work on a consistent basis. My car got broken into because the locks don't work. I just replaced three of the four locks for around $1,200.00. Neither the key fob nor the actual key would open the doors on the vehicle. This is an extreme safety issue in case of emergency, and it really makes me mad. It is a well-known defect which is commented on countless vehicle websites. There were no warning messages, the locks just stopped working.

    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

    Having major problems with door lock actuators. just replaced front passenger side for 950 dollars at Toyota dealer and was told the other 3 doors may start failing as well. I did not realize at first that the door was not locking which would make it so easy for someone to break into my car.It is a 2014 Toyota 4runner. Sure enough the front driver side door is not locking. I need to spend another 950 dollars to get it fixed. What is wrong with these actuators? Now the replacement actuator I had put on the passenger side is giving me problems with the door opening and closing. What next?? Toyota should definitely have a recall on these actuators. It appears that I am not the only one having problems. This is a security issue.
