THE 4RUNNER STRUCK A VEHICLE THAT RAN A RED LIGHT. THE 4RUNNER WAS AT APPROXIMATELY 35 MILES PER HOUR AND STRUCK THE OTHER VEHICLE, A NISSAN ALTIMA SIDE ON WITH ENOUGH FORCE TO PROPEL THAT VEHICLE TWO LANES INTO ANOTHER VEHICLE. THE AIRBAGS FAILED TO DEPLOY ON THE 4RUNNER BUT DID DEPLOY ON THE ALTIMA. THE ROADS WERE DRIVE AND VISIBILITY WAS CLEAR. INJURIES TO THE 4RUNNER DRIVER INCLUDED: HEAD FROM CONTACT WITH GRAB BAR ABOVE DRIVERS DOOR, NECK, BACK, WRISTS, FINGERS AND ARMS. ALTIMA DRIVER HAD TO BE REMOVED BY PARAMEDICS AND RUSHED TO THE HOSPITAL. INVESTIGATION OF THE VEHICLE COMPUTER SHOWED THE VEHICLE WAS UNKNOWINGLY SOLD TO ME WITH ERRORS IN THE MULTI-TERRAIN, ESC AND PRE-COLLISION SYSTEM. VEHICLE WAS PURCHASED IN NOVEMBER OF 2019. SEE ATTACHED PHOTOS FOR VERIFICATION.

WHILE I AM DRIVING, I SMELL SOMETHING LIKE EXHAUST OR SULFUR INSIDE CAR. I COULD ONLY SMELL IT WHEN THE CAR IS GOING OVER 70 MILES, RPM IS OVER 2500 (HARD ACCELERATION) , AND WHEN ALL THE WINDOWS ARE CLOSED AND RECIRCULATE CABIN AIR IS ON.

THE FRONT PASSENGER AIRBAG ON THIS CAR IS DEACTIVATED AUTOMATICALLY WHENEVER THE FRONT PASENGER WEIGHS LESS THAN 100 LBS. WE DID NOT KNOW ABOUT THIS FEATURE WHEN WE BOUGHT THE CAR. MY WIFE, WHO IS 65 YEARS OLD, WEIGHS ABOUT 95 LBS AND WHENEVER SHE SITS IN THE FRONT PASSENGER SEAT, A WARNING LIGHT APPEARS INDICATING THAT THE FRONT PASSENGER AIR BAG HAS BEEN DEACTIVATED. WE CONTACTED THE DEALER AND TOYOTA AND WERE TOLD THAT THIS SYSTEM WAS DESIGNED TO AUTOMATICALLY PROTECT SMALLER CHILDREN WHO MAY RIDE IN THE FRONT SEAT. UNFORTUNATELY, THIS SYSTEM PREVENTS MY WIFE FROM USING WHAT I CONSIDER TO BE AN ESSENTIAL SAFETY FEATURE (THE FRONT AIR BAG). THE NHTSA SHOULD MANDATE THAT MANUFACTURERS PROVIDE US WITH A SWITCH OR A SYSTEM SETTING THAT ALLOWS THE DRIVER TO ACTIVATE THE FRONT PASSENGER AIRBAG AND OVERRIDE THIS "CHILD SAFETY FEATURE". IT CERTAINLY IMPACTS MY WIFE'S SAFETY EVRYTIME SHE SITS IN THE "DEATH SEAT".

EVERY TIME I PUSH THE BRAKE PEDAL, IT MAKES A HISSING SOUND. THERE IS A ELECTRONIC NOISE AFTER THE HISSING SOUND. THIS IS ANNOYING AND IT MAKES ME FEEL NAUSEOUS.

4/9/2020

BRAKES ARE NOT FUNCTIONING PROPERLY, THE PEDAL GOES WAY DOWN TO THE FLOOR BEFORE ENGAGING ANY BRAKES. AT IDLE THE BRAKES SEEM TO FUNCTION FINE, AFTER DRIVING AT ABOUT 10MPH THE BRAKES GO BACK TO NOT WORKING AGAIN. DEALERSHIP SAYS THE BRAKES ARE "NORMAL" AND I WAS TOLD TO DRIVE IT HOME EVEN THOUGH IT WAS STILL HAVING THE ISSUE. TRANSMISSION IS NOT SHIFTING PROPERLY EITHER, IT GETS STUCK AT 4000-5000 RPM SOMETIMES AND THEN SHIFTS INTO THE NEXT GEAR. THE BRAKING ISSUE OCCURRED EVEN WORSE GOING DOWN A HILL AT 55MPH RIGHT BEFORE IT WENT IN FOR SERVICE.

STEERING WHEEL SHAKES DRIVING 58-62MPH ON HIGHWAY

9/17/2020

Steering wheel shakes at highway speeds (58-64mph). Steering wheel has shaken as much as 1.5 inches back and forth, causing vehicle to shake while driving at high speeds. The problem has been confirmed by the dealer and has been in 6 times to try to fix it with no change. The problem started the second week we owned it. It gets progressively worse. Tires can be balanced and it comes right back a few days later. Toyota corporate states that it is a known issue and “is a characteristic of the vehicle” cause by “harmonics.” Tires have been road force balanced, tire/wheels swapped, driven with no drive shaft, driven with computer to turn off torque converter, drive shaft swapped- all with no change. Toyota would not agree to provide loaner car after requesting buyback arbitration. I was told it would take 30-45 days to get arbitration started, and was told to drive the vehicle during that time period. I was told to return loaner and drive 4Runner that was still shaking. I asked dealer to give me something in writing saying that the vehicle was safe and mechanically sound before I left, and they refused.

I BOUGHT MY 4RUNNER BRAND NEW LAST YEAR. TO CHANGE THE DIFFERENTIAL FROM H4F TO H4L, I STOP THE CAR AND CHANGE THE SHIFTER INTO NEUTRAL POSITION. ONCE IN NEUTRAL POSITION, I CHANGE THE DIFFERENTIAL KNOB H4F TO H4L. THEN I START DRIVING AGAIN. MY EXPECTATION IS THE WHEN SHIFTING THE DIFFERENTIAL FROM H4F TO H4L, THE DASHBOARD LIGHT WILL CHANGE FROM YELLOW TO GREEN JUST LIKE MY PREVIOUS 4RUNNER. BUT THIS MODEL DOES NOT CHANGE FROM YELLOW TO GREEN TO IDENTIFY SUCCESSFUL TRANSFER OF GEAR FROM HIGH TO LOWER GEAR. THE DASHBOARD COLOR STAYS YELLOW. I BELIEVE THIS IS A DEFECT. I BELIEVE THERE IS A DEFECT IN DIFFERENTIAL LOCKING MECHANISM OR AT THE VERY LEAST THE LELECTRONICS THAT UPDATES THE DASHBOARD. THE NEW MODELS ALSO HAVE SAME ISSUE. I BELIEVE ANYTIME YOU SEE A YELLOW LIGHT IN THE DASHBOARD, IT IS A WARNING MESSAGE THAT SOMETHING IS WRONG OR WILL BE WRONG IN THE FUTURE. TOYOTA DEALERS SAID THIS IS A STANDARD COLOR BUT I DONT BELIEVE BECAUSE THEIR MANUAL SAYS YELLOW COLOR MEANS WARNING.

3/31/2021

The car shakes when going at speeds as low as 48 mph and as high as 68 mph that I know of. Typically, it shakes heaviest from the mid-50 mph range to the mid-60 mph range. I rarely Drive the full speed limit for energy conservation reasons, so I cannot tell you how much higher it goes on the range. The car has had the wheels rebalanced three times (installation, upon purchase from the dealer and on a take back to the dealership), the alignment has been checked twice and I have spoken to the tire manufacturer about the tires being the cause of this. I took the tires into an authorized retailer to no avail. With everything checked, including a road force balancing of the tires, my 4Runner still shakes disturbingly. I called a service advisor at another Toyota dealership today (they were not the seller). In describing the problem to him, he cut me off and said it is a known problem. He went on to share that the dealership had been in contact with Toyota Corporate. It is disturbing for me as a driver, my passengers and from an engineering standpoint; shaking can never be good. It could easily cause premature and unnecessary wear to drive, suspension and steering parts. It could lead to a serious and fatal accident over time. The shaking, I imagine, could also lead to a problem in less than ideal driving conditions such as rain, snow or ice as well.

Took the vehicle in 3/19/2021 @ 6076 Mileage for a steering wheel shake, the dealer has tried numerous times to fix it by trying to balance the tire and rotate the tires, it only masks the problem and the steering wheel shake comes back. The shake can happen at any MPH. I finally took it to another shop called discount tire and dynamic 4x4 alignment. Discount tire said there was coupling in the stock tires Nitto Grappler, so I replaced the tires with Michelin Defenders this only masked the problem. On 9/25/2023 a local Toyota Technician and I took a ride together to see if he could duplicate the problem. At 67 and 68 we were able to duplicate the problem when the steering wheel shook the passenger side of the car shook. The technician and I swapped and I was able to duplicate the problem as well. I was stopped at a red light and took off after the tires were warmed up. When I reached 67 or 68 mph the steering wheel began to shake and he confirm that the vehicle shook too on the passenger side. I have experienced shaking in the steering wheel previously but now its being felt in the vehicle too. Toyota sent out a technician on the last issue and I was told they found something and then I was told there was nothing. Please see notes below as I have documented every occurrence and can provide maintenance documentation too.

System malfunction—the ‘brake’ alert flashed and chirped when there was NO obstacle on the road. Safety issue—I was about to hit the brakes but I realized in time there was no need. Confirmed? No not at this time. Possibly have it reviewed at next maintenance. No inspection yet. This has occurred infrequently in the past

EXTERIOR LIGHTING

1 Report2% of total

Previewing the first 1 complaint summaries.

Similar to NUMEROUS newer ('12+) vehicles, the instrument cluster gauge needles light up even when the headlights are not on. Therefore when driving the vehicle, the driver isn't aware that the headlights are NOT ON at night (and there are no DRL/daytime running lights to warn oncoming drivers), which means that the vehicle is driving at night WITHOUT any lights on. People are going to be killed this way; both the driver and innocent motorists driving near this vehicle. I nearly got in a head-on collision last night because the vehicle headlights weren't on after sundown (but I listed crash, fire, fatalities to get your attention, as I submitted this same issue about 8years ago for a similar incident with a Nissan Leaf that narrowly missed running me over as it was driving without any headlights on/LED gauge cluster was bright enough to see the drivers face, and NOTHING has changed in the auto industry for safety on this widespread issue). How can the automotive industry and NHTSA have let this happen? Instrument cluster gauges should not have ANY backlighting unless the headlight switch is physically activated by the driver. This issue is even worse with the new LED/virtual gauge cluster screens.
