Each component in detail
What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
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
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
TL* THE CONTACT OWNS A 2015 TOYOTA 4RUNNER. THE CONTACT STATED THAT HE WAS UNABLE TO LOCK AND UNLOCK THE PASSENGER'S SIDE DOOR. THE CONTACT CONTACTED KERRY TOYOTA SERVICE FLORENCE (6050 HOPEFUL CHURCH RD, FLORENCE, KY 41042; (859) 371-1518) AND THE VEHICLE WAS DIAGNOSED WITH A DEFECTIVE PASSENGER'S SIDE LOCK ACTUATOR. THE CONTACT WAS INFORMED THAT THE LOCK ACTUATOR NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND INFORMED OF THE FAILURE. THE CONTACT WAS REFERRED TO THE NHTSA FOR ASSISTANCE. THE APPROXIMATE FAILURE MILEAGE WAS 50,000.
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. AFTER 2 MONTHS AND MULTIPLE PHONE CALLS TO HIM HE SAID THEY HAD SEEN THIS PROBLEM IN OTHER VEHICLES AT OTHER DEALERSHIPS AND CORPORATE APPROVED HIM TO REPLACE THE COMPUTER FREE OF CHARGE SINCE MY CONCERNS HAD BEEN DOCUMENTED AT MANY SERVICE INTERVALS WHILE THE VEHICLE WAS STILL UNDER WARRANTY. I AM VERY DISAPPOINTED IN HOW LONG IT TOOK TOYOTA OF SAN LUIS OBISPO, CA TO ACKNOWLEDGE THE PROBLEM AND AGREE TO DO THE REPAIR. I HAD TO GET VERY ASSERTIVE AND PERSISTENT IN ORDER TO GET THEM TO LISTEN TO MY CONCERNS AND FIX THE PROBLEM. I WANTED TO DOCUMENT THIS PROBLEM IN CASE ANYONE ELSE MAY HAVE THE SAME ISSUES.
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
Drove the car on empty tank and I had issues the following day after I refilled $60 gas.Car stalling/ hard to turn on, doesn’t stay on.
Toyota 4 runner had a recall for the fuel pump. I have been having starting issues with it ever since. The power is good and the starter tries to turn the vehicle over. But the vehicle won't start. I have taken it to multiple locations for service through out the chicago land area. Also once the vehicle finally does start. The R.P.M.s will suddenly increase and decrease to the point that the vehicle turns off while in drive. I can provide print outs when the vehicle gets fixed, if ever. I purchased the vehicle as CPO.
Suspension
Reports naming suspension components — springs, struts, shocks, control arms and related hardware.
From owner reports, verbatim
Front Coil Spring Cracking (TRD Pro Models) I observed cracking of the front coil spring, a design defect in the spring's termination and how it sits on the top hat and bottom perch. This can lead to a sudden loss of control and a crash. Furthermore, pieces of the broken spring coil can fly out underneath the vehicle and cause serious injury to person and/or damage property, when vehicle is driven at highway speeds.
'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.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
I CAME HOME FROM WORK AND REVERSED MY 4RUNNER INTO MY GARAGE AS I NORMALLY DO. THE NEXT MORNING, MY 4RUNNER STARTS AND THE ENGINE SOUNDS NORMAL BUT IT WON'T MOVE WHEN I SHIFT THE GEAR FROM PARK TO DRIVE. I STEPPED ON THE GAS WHILE LEAVING THE GEAR IN DRIVE, THE RPM MOVES BUT THE 4RUNNER STAYED IN THE SAME SPOT. *TR
MULTIPLE TIMES NOW WHILE DRIVING UNDER NORMAL CONDITIONS WE HAVE EXPERIENCED THE INSTRUMENT PANEL GOING ROGUE. ABS, VSC, GAS, CHECK ENGINE, ALL LIGHTS WILL RANDOMLY COME ON. THE SCARY PART IS THIS MOST RECENT TIME IT JUMPED THE SPEEDOMETER WAY UP AS WELL. ANY HELP WOULD BE GREATLY APPRECIATED!
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
My transmission went off with no warnings and my vehicle has been serviced at the Toyota dealer since I bought it and they never mentioned to me there was an issue with my transmission which is very odd. So I was wondering is this is normal or if there others owners with the same problem. Now I don’t have a vehicle because the transmission is in back order and I can’t even get a rental car because it wasn’t an accident or a recall. So I would like for you to look into this issue for this Toyota model.
The contact owns a 2015 Toyota 4Runner. The contact stated that on four occasions while diving at various speeds, the vehicle stalled. The vehicle was restarted after approximately 10 minutes after each failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 143,400.
Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
All of a sudden it was so difficult to steer I ended up off my driveway and almost took out my chain link fence. Two hands on left side of the steering wheel and yanked with all my strength. Then across my drive to the left. If this had happened turning onto a highway someone could have been killed.
Steering shudder at 58-70 MPH has become almost unbearable. No warning lights whatsoever - ever! Vehicle has had this issue since 30K miles (110K currently) and Toyota always is "unable to replicate the issue" or tells people this is common on the 4 Runners and Tacoma's. I won't go to dealers anymore since Toyota knows it's a problem and they direct the dealers not to report to keep the issue cluster diluted. Any visible wheel shake, no matter what speed should not be considered "common". Just replaced all 4 tires with Pirelli Scorpions, did the recommended Toyota road force balance and had everything aligned. Doesn't drive any differently than with the old tires and out of alignment. Perhaps if the Toyota brass had to drive their OWNfamily in this vehicle, they would take a different position. Guess it will unfortunately take some highway fatalities in these vehicles before manufacturer or governments act. I'm praying for a class-action suit as there are 1000s of 4 Runner customers experiencing the same issue. Many of whom have sold at a loss just to get away from an unsafe vehicle. First Toyota I've owned and it will be the last.
Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
Noticed the frame on the passenger side of the vehicle is rusting and I’m concerned about a safety issue. I know there was a rust-related class action on earlier model Toyota’s. The rust is most prevalent on the solder joints, which has me concerned about driving safety.
BOTH THE DRIVER SIDE DOOR AND PASSENGER SIDE DOOR DO NOT OPEN WHEN WHEN REMOTELY ACTIVATED. THEY ALSO CANNOT BE LOCKED REMOTELY. I HAVE NO WAY OF OPENING THE PASSENGER SIDE DOOR FROM THE OUTSIDE. BOTH DOORS HAVE TO BE MANUALLY OPENED. THE DRIVER SIDE CAN BE OPENED BY THE KEY, BUT THE PASSENGER SIDE NEEDS TO BE OPENED INSIDE THE PASSENGER DOOR.. THIS IS A SAFETY ISSUE ESPECIALLY WHEN MY WIFE TAKES THE CAR. IT IS DANGEROUS THAT SHE CANNOT ENTER THE CAR IN A TIMELY MANNER OR EVEN LOCK THE CAR.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
I CAME HOME FROM WORK AND REVERSED MY 4RUNNER INTO MY GARAGE AS I NORMALLY DO. THE NEXT MORNING, MY 4RUNNER STARTS AND THE ENGINE SOUNDS NORMAL BUT IT WON'T MOVE WHEN I SHIFT THE GEAR FROM PARK TO DRIVE. I STEPPED ON THE GAS WHILE LEAVING THE GEAR IN DRIVE, THE RPM MOVES BUT THE 4RUNNER STAYED IN THE SAME SPOT. *TR
MY HUSBAND PARKED THE CAR ON A HILL IN FRONT OF A GAS STATION AND I STAYED IN THE CAR SITTING ON THE PASSENGER SEAT AND IT JUST ROLLED DOWN THE HILL, CAUSED AN ACCIDENT TO A PARKED CAR GETTING GAS, I JUMPED OUT OF THE CAR AS IT ROLLED TOWARDS A GAS PUMP , SLAMMED ON TO PUMP GUARD. THANKFULLY NO ONE WAS HURT BUT ME WHEN I JUMPED OUT OF THE CAR.POLICE REPORT FILED

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
AT 20,202 THE SUV'S STEERING WHEEL WOULD SHAKE WHEN BRAKES WERE APPLIED. THE DEALER NOTED THAT THE ROTORS WERE WARPED, GLAZED AND HAD HEAT SPOTS. VEHICLE QUALIFIED FOR REPLACEMENT BRAKES UNDER WARRANTY, REPLACED BRAKE PADS AND ROTORS FRONT ONLY. SINCE REPAIR, THE FRONT WHEEL STARTED TO SHAKE AGAIN - DEALER SAID TO GET NEW TIRES TO SOLVE PROBLEM. GOT NEW TIRES AT ~47,000. PROBLEM STILL EXISTED, AND TOOK TO DEALER FOR REGULAR SERVICE AND TO ADDRESS BRAKE PULSATION WHEN APPLYING PEDAL. THE DEALER, NORTHRIDGE TOYOTA, DECLARED THAT "THE PULSATION IS A WEAR OR DRIVING PATTERN ISSUE" REFUSING TO FIX THIS OBVIOUSLY DEFECTIVE BRAKING SYSTEM. RECOMMENDING THE SAME ROTOR AND PAD REPLACEMENT AT A COST OF OVER $660.00. MANY DOCUMENTED COMPLAINTS OF THIS SAME PROBLEM ON THIS NHTSA WEBSITE.
WHILE BRAKING AGGRESSIVELY ON A DRY STREET IN A STRAIGHT LINE, THE ABS SYSTEM KICKED IN FOR A BRIEF SECOND AND THEN IT RELEASED THE BRAKES ALL TOGETHER - RESULTING IN COMPLETE LOSS OF ALL BRAKING CAPABILITY. BRAKING CAPABILITY WAS RESTORED AFTER THE PEDALS WAS RELEASED ALL TOGETHER AND RE APPLIED. THIS HAPPENED TWICE OVER THE PAST 6 MONTHS. ON 2017/10/13 I TOOK THE VEHICLE IN FOR A COMPREHENSIVE INSPECTION OF THE BRAKING SYSTEM BY A TOYOTA AUTHORIZED DEALER BUT THEY HAD NOT IDENTIFIED ANY FAULTS AND CLAIM THE SYSTEM IS OPERATING AS EXPECTED.

Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
TL* THE CONTACT OWNS A 2015 TOYOTA 4RUNNER. WHILE DRIVING 60 MPH, AN EXPLOSIVE NOISE WAS HEARD. THE CONTACT COASTED THE VEHICLE TO THE SIDE OF THE ROAD AND DISCOVERED THAT THE SUN ROOF EXPLODED WITHOUT IMPACT OR WARNING. THERE WERE NO INJURIES. THE CONTACT DROVE THE VEHICLE TO HER RESIDENCE. THE CONTACT CALLED JIM HUDSON TOYOTA AT (803) 407-5678 (LOCATED AT 970 COLUMBIANA DR, IRMO, SC 29063) AND WAS INFORMED TO CALL HER INSURANCE COMPANY. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND ADVISED THE CONTACT TO TAKE THE VEHICLE TO A DEALER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 56,000.
I HAD 20,000 MILES AND BOUGHT THE VEICHLE BRAND NEW AND WENT TO LEAVE WORK AND MY VEICHLE WAS STRUGGLING TO STAY GOING AND MY CHECK ENGINE LIGHT WAS FLASHINING. WHEN I'D GO TO REVERSE THE VEHICLE WOULD STRUGGLE AND ACT LIKE IT WAS GOING TO DIE. I HAD TO GO 20MPH ON THE SIDE ROADS ABOUT 15 MILES TO THE DEALER. THE RPM SHOULDN'T SHIFT. IT WAS CAUSED BY A MOUSE I GUESS? SINCE THEY USE SOY BASE AND SEE THIS A LOT. SO FUSTRATING WHEN YOU PAY $38,000 FOR A VEICHLE. I'D MUCH RATHER DRIVE MY OLDER 2010 HONDA THAT NEVER HAD AN ISSUE WITH SO CALLED A MOUSE. THEY OF COURSE WOULDN'T COVER IT. TO TOP IT OFF I HAD A MAJOR OIL LEAK AT 19,000 MILES CAUSING ABOUT $6,000 WORTH OF DAMAGE. WHICH WAS THE FACTORY'S FAULT THEY SAID. IT WAS COVERED BY WARRENTY, BUT STILL IT'S RIDICULOUS. I BOUGHT THE CAR NEW. WITH 1 MILE ON IT, FRESH OFF THE TRUCK. AS OF RIGHT NOW I HAVE NO FAITH IN TOYOTA. I'M AFRAID MY VEICHLE WILL BREAK DOWN ON ME. WHICH I SHOULDN'T HAVE TO FEEL WHEN I BUY A NEW CAR. SO DISAPPOINTED IN TOYOTA. SOMETHING NEEDS TO BE DONE.

Interior & seats
Reports naming seats, latches, locks, linkages and interior fittings.
From owner reports, verbatim
The door lock actuators have failed on both the driver side and passenger side front doors. Unfortunately this is a know issue across this model along with others and can be found in several forums. The problem is that the actuator gets stuck and at one point I was locked inside my car and once I was locked outside my car. If there was an emergency it could put mine and others safety at risk if the lock fails. The vehicle was inspected by Toyota who stated the actuators need to be replaced at $805 a piece and will not fix it themselves even though it is a known problem. This happened within the last month.
THE FRONT DRIVER SEAT PLASTIC SKIRTING CLIPS BROKE CAUSING THE SEAT SKIRTING TO TWIST UPWARD AGAINST THE DRIVERS LEG. SEEMS LIKE A DESIGN FLAW WHERE THE POWER SEAT WILL MOVE MORE THAN THE PLASTIC CLIPS CAN HANDLE RESULTING IN WEAR THEN BROKEN CLIPS. TOYOTA OF SAN LUIS OBISPO, CA REPLACED THE SKIRTING WHILE THE VEHICLE WHILE WAS UNDER WARRANTY. ONE MONTH LATER THE CLIPS BROKE AGAIN. TOYOTA OF SAN LUIS OBISPO, CA TOLD ME THERE WAS NO FIX FOR THIS AND IT WOULD JUST CONTINUE TO HAPPEN AND A SECOND REPLACEMENT WOULD NOT BE APPROVED.

JUST BOUGHT 80K MILE WARRANTY TIRES ARE THEY ARE COMPLETELY BALD AT 20K MILES EVEN AFTER BEING ROTATED EVERY 5K MILES, BALANCES, AND ALIGNMENTS.

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
THE 4RUNNER'S ELECTRICAL SYSTEM SHUTS DOWN COMPLETELY WHILE DRIVING; AS IF SOMEONE WAS SUDDENTLY TURNED THE CAR OFF WHILE DRIVING THEN TURNED IT BACK ON. ALL DASH LIGHTS, INSTRUMENTATION, HEADLIGHTS, RADIO, ETC... SHUT DOWN AND THEN IT RESTARTS AUTOMATICALLY SHORTLY THEREAFTER. THIS HAPPENS MULTIPLE TIMES DAILY. IT OCCURS BOTH WHILE THE CAR IS IN PARK OR REVERSE OR DRIVING USUALLY BELOW 555MPH SINCE MUCH OF MY COMMUTE IS CITY VS. HIGHWAY. IT STARTED WITH THE RADIO HEAD UNIT ONLY THEN THE ISSUE HAS PROGRESSED TO THE ENTIRE ELECTRICAL SYSTEM. THIS SHOULD BE INVESTIGATED AS THIS IS A MAJOR SAFETY ISSUE AND COULD LEAD TO INJURY.
