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 the federal safety agency 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.

Defect investigations
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

Most recent owner complaints, unedited.
White Paint Peeling From Metal Body Panels
The contact owns a 2014 Toyota 4Runner. The contact purchased four Bridgestone tires in 2022, Tire Line: Alenza AS Ultra, Tire Size: 245/60/R20, DOT Number: 1RBTEAAU1. The contact stated that all four tires had developed cracks on the sidewalls and by the tire beads. The tires were replacement tires. The tire dealer was contacted and advised the contact that it was normal wear on the tires. The manufacturer was notified of the failure. The tire failure mileage was approximately 20,000. The vehicle failure mileage was 80,000.
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.
paint is peeling on my 2014 Toyota 4runner . Toyota recalled for white paint but nothing for blue . i already paid so much for the car but not paying extra for the paint . Toyota should fix it .
Vehicle was involved in an accident where the driver side airbag did not deploy.
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.
Left rear Brake Caliper Failure, Both Front Struts and both rear shocks were worn out per dealership. Had to replace all above.
Stumbling/Studering and hesitation when accelerating took it to dealership and they performed a tune-up and complete fuel system service when to pick it up and still doing the same thing. Dealership rechecked it and said Torque converter was faulty. Had to replace transmission.
The handsfree calling/talking is unusable neither party can hear the other due to it echoing and has very distortion. So I'm unable to use my handsfree talking while driving.
