NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2015 Toyota 4Runner:
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.
What 2015 Toyota 4Runner owners say
Air bags
I was just in my second front end collision and for the second time, my front airbags did not deploy. The first instance, I hit a deer head on going 75 mph on the interstate. Last week, I T-bone F150 at 35mph - hard enough to make that truck spin around - and had injuries to my head, knee, and hand, and yet the airbag did not deploy once again. In both cases, my car sustained over $10,000 and damage to the front end.
My 4 runner was hit on the passenger side while crossing a intersection. The truck that hit my 4 runner was going at least 40 miles per hr and was a heavy duty pickup truck. On impact the airbags did NOT deploy but the 4 runner went haywire.
Electrical system
When the vehicle is put in reverse the computer screen rear view camera image becomes blury, the image shakes rapidly and static with neon lines would appear distorting the camera footage. It made the rear camera screen view unusable and unreliable. This happened off and on for over 2 years and during each service I would ask Toyota of san luis obispo, ca to diagnose and fix the problem. They would tell me they were not able to duplicate the problem and that they updated the computer chip and it "should be good". This did not resolve the problem. I was able to video tape the problem and showed the video to the service manager. He had me send him my video and said he needed to talk to corporate. …
Entune radio/navigation system continually crashes and stalls while driving causing safety hazard if driver has to continually reset the radio power while driving. This usually happens more so when the navigation system is engaged. It will crash out of no where, use to just happen with instructions were being given through the speaker now its random. Happens also when with just music playing, will be unable to change stations or control volume with buttons or nobs. This seems to be happening to a large amount of customers who have no way of solving the issue. Might be need for safety recall as people May need to continually reset or try to figure out whats wrong while driving. …
Suspension
This is our third Toyota 4Runner with the "X-REAS Sport Enhancement Suspension System". There has been some type of failure of this system on all 3 of the 4Runners we have owned. The latest problem with this suspension system on our 2015 4Runner was discovered during a Toyota dealership service appointment at 42,091 miles. It was recommended the full X-REAS system, front and rear shocks with lines and actuators be completely replaced since both front shocks are leaking fluid at a cost of $4,000. Since this is our third 4Runner with this suspension and related problems it is our fear that this suspension system might fail when driving and possibly cause an incident with who knows what could happen. …
'The "KDSS" (kinetic dynamic suspension system) valve located on the frame under the driver's door had corroded to the point where the oil in the system had begun to leak out. The warning light did come on the dashboard days prior to the leak. Vehicle was taken to a Toyota dealership, where they assessed there was low pressure in the system. The service advisor advised that if the system loses all the fluid, the suspension and handling may be affected when steering or braking at high speeds or when making sharp turns.
