2015 Toyota Highlander Electrical System Problems

Exterior lights continually burn out.

When right front pax sits in seat and fastens seatbelt, the airbag indicator correctly says "ON." But after a few minutes, the airbag turns "OFF" and the driver's dash gets an "unfastened seatbelt" warning and a "faulty airbag" warning. All of these occur while the front right pax has remain seated and buckled. If the pax unbuckles and exits the seat, these incorrect warnings all remain the same. The right front pax seat belt buckle has been replaced with no effect. The seat has been recalibrated (seat sensors) with no effect. The wires under the seat have been disconnected, cleaned, and re-connected with no effect. This is a safety issue in that the airbag on that front right side de-activates when a passenger is in that seat. There is a Toyota Recall Campaign for this identical problem, but it does not include my model year (2015). Requesting NHTSA get Toyota to extend their recall to include 2015 models, please.

The contact owns a 2015 Toyota Highlander. The contact stated while driving 65 MPH, the vehicle stalled, and the steering wheel became difficult to turn. The check engine warning light and several other unknown warning lights were illuminated. The contact was able to pull into a parking lot. The contact was able to restart the vehicle after 45 minutes. The vehicle was taken to an independent mechanic, but the vehicle was not diagnosed or repaired. The dealer was notified of the failure and charged a fee for diagnostic testing. The contact related the failure to NHTSA Campaign Number: 18E107000 (Electrical System, Visibility); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 193,000.

The contact owns a 2015 Toyota Highlander. While stopped at a gas station with the engine on, the contact's wife smelled an abnormal, burning odor coming from the vehicle without warning. Upon inspecting the vehicle, the contact's wife saw flames shooting from the dashboard near the infotainment system; the contact's wife and children immediately exited the vehicle. The fire department was called to the scene and extinguished the fire. The contact's wife suffered minor burns on her right hand but did not seek medical attention. The contact had the vehicle towed back home where it remained in the contact's possession. The manufacturer was notified of the failure and a claim was filed. The vehicle had yet to be diagnosed or repaired. The failure mileage was approximately 104,000.

My Highlander had a strange burning smell and we couldn’t find where it was coming from. We took it to a shop where they checked everything over and suggested that the smell was our brakes. They lubricated the brakes and replaced my tires and struts. When I went to pick up the vehicle I still noticed the strange smell, and I had the mechanic come out and check. He suggested that it was the leather conditioner that our detailer had used. I left and headed for home and in about 5 miles the control for the drivers heated seat started smoking and about 30 seconds later the plastic around the control began to melt and flames were coming out of the area next to the control. I was able to use a fire extinguisher to put the fire out. All of the heated seat components were original and we haven’t had any work done to it. The obvious safety concern here would be fire in the cabin of the vehicle while in motion. The fire and sheriffs departments showed up to the scene and the incident report was filed. The vehicle was towed to a shop where we are awaiting insurance adjuster to look at it. There were not any warning lights or signals of any kind; only the smoke very shortly before the visible flames.

I have a 2015 Toyota Highlander XLE. Last winter I began noticing a burning smell which I believed to be electrical inside the vehicle. I was able to determine it was the driver seat heater and the burning smell continued even with the toggle switch turned off. I stopped at a local Toyota dealership, Koch Toyota, who refused to show me which plug under the seat to unplug to disconnect power. They tried to insist that I drop the car off and let them check it. Due to past negative experiences with that Toyota dealership I refused. I was able to speak to my own mechanic who instructed me to remove the fuse for the driver's seat heater which I did and the smell stopped however the seat heater is not functioning now. Upon recent research online it appears this is a common problem especially in 2015 Toyota Highlanders. I found a couple other owners of the xle models on a website called Toyota Nation who experienced similar problems where their vehicles actually caught fire and melted the center consoles after the burning smell was misdiagnosed. I believe this is a huge safety concern and have recently filed a report with Toyota Corporate in hopes to get the issue rectified. There were no warning messages or lights that came on to advise that there was an issue.

We have a 2019 Toyota Highlander. VIN: [XXX] . There are two issues with this vehicle... 1) Our bumper fell down after an uneventful car wash. We didn't hit anything. Reported it to the car wash place (Ollie's Car Wash in Walker, LA) after we noticed it fell. We had to tie-strap it back up because the clips no longer worked right. This happened August 12, 2023. We have pictures of the damage. 2) A second issue is totally separate from the first. This one has to do with the back lifting door. It often gets stuck to where we have to manually force it closed. We have to reset the button often. Sometimes it gets stuck open and sometimes it won't open at all. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I experienced a sudden engine failure while driving my 2015 Toyota Highlander on Interstate 294 outside Chicago. I was driving about 75 mph in the far left lane. A warning message "Check AWD" came on the screen, followed by the Engine icon lighting up, then a "TRAC off" message appeared on the screen. I began to merge to the right across four lanes of traffic to get to the shoulder. As I was doing so, a beep sounded, and the message "Engine Stopping" appeared on the screen. The accelerator stopped working. I reached the shoulder and the car came to a stop just as I made it to the shoulder. The whole incident, from the time the first warning light came on until the car completely stopped, lasted about three minutes. Prior to this, there were no warning lights, and I had been driving the car without incident. The car had received all regular maintenance at proper intervals. Mileage was 86,100 at the time. There were five people in the car, including myself, my teenage daughter, her friend, and her friend's parents. We were driving the girls home from a summer camp. We are unharmed -- and possibly alive -- only because I was able to merge across four lanes of traffic and reach the shoulder before the engine completely failed. Just behind us and just ahead of us on this stretch of interstate, there is no shoulder. Semi trucks populate this very busy road. We had to sit on the shoulder for two hours waiting for a tow truck. We are all truly fortunate to be alive and unharmed. The vehicle is in the possession of [XXX] Toyota, [XXX] . The service department has diagnosed as follows: "Performed diagnostic and found codes P0300, P0301, P0302, P0303, P0306 engine misfire codes. Code P1603 Engine stalls out. P1604 Stability malfunction. Code P1605 Rough idle. Spark plug number 6 is damaged. Check piston with borescope, piston is also damaged." I am being advised to replace the engine at a cost of $8820. Toyota US has been notified. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On Jan 25, 2022 while sitting in my car... engine running. Smoke filled the inside of the vehicle. Prior to seeing smoke I smelled electrical smell and also my heated seat was warmer than usual. I did not think nothing of it. Smoke definitely came from the knob to turn heated seat on with and also appeared to be coming from the vent. I shut the car off. Thirty to 45min later I turned the car back on. More smoke came but it cleared out with me letting all windows down. Afterwards the panel to control air was completely out along with the clock. The clock came back on later while blinking. I immediately called Toyota Corp. I have case numbers each time I called. I took it ti the Toyota dealership with assistance of Toyota Corp. My car has been at Toyota universe in little falls, nj and they have yet to fully explain what is going on with the defective that occurred in my car. They do not call you back. I've had to go there to get answers due to them not returning calls.

actuators, yes it's available for inspection The actuators on all the door are going out, they randomly work. It's a safety issue if you needed to exit the car for any emergency or making sure your car is locked and secured. You're at risk due to it simply not working, getting into the car it's a security issue, presents issues for parent(s) with children, children with disabilities, driver/passengers with disablities. When the car is put into reverse, they will not automatically lock as they should. Same when put into park, they do not automatically lock or unlock. Yes, the dealer confirmed the issue. The driver door actuator has been replaced but the other doors need to be replaced now as well. To my knowledge the faulty actuator has not been inspected No warning it just happened. but when they due fail to lock when using the keypad the car doesn't confirm the lock and security is set. When they fail to unlock using the keypad the car continues to beep several times after hitting the unlock button. You have to manually reach/maneuver to lock or unlock the door.

The door locks have stopped working one by one. First I noticed the driver door not unlocking or locking with the key fob, with the touch system on the door handle, or with the button on the inside panel. Then I noticed my back door on the driver side not locking or unlocking with the key fob OR with the button on the inside panel. Both of these locks are now manual only. And the front passenger door lock only works sometimes, so I imagine it will stop working altogether soon as well. This puts the safety of my belongings, myself, and my children at risk. I don't know how long this had been happening before I noticed it, so I very easily could have been unknowingly leaving my car unlocked all over town. I am unable to enter my car quickly because I have to take the key fob apart and use the manual key to enter the driver door, and then my son has to wait for me to manually unlock his door before he can get in. My daughter sits on the other side so he can't just switch to the side that works. Well he could but then my daughter would have the same issue. If it was an emergency situation and we had to get into the car quickly it's just not possible. Also in traffic or in parking lots when we are inside the car I feel like we are left vulnerable with the doors unlocked and I can't lock them without reaching and manually doing this for each door. Which I do, but shouldn't have to. A quick internet search has made it clear that I am FAR from the first person this has happened to with these vehicles. It is clearly an extremely common issue with Highlanders and other Toyota vehicles and it 100% should be a recall.

THE SCREEN FREEZES AND RESTART FOR NO APPARENT REASON. THE SITUATION IS HAPPENING WITH MY VEHICLE IS IN MOTION OR STATIONARY.

DOOR ACTUATORS ON BOTH REAR PASSENGER DOORS HAVE STOPPED WORKING. DOOR LOCKS DO NOT RESPOND TO POWER DOOR LOCK SWITCH NOR THE KEY FOBS.

REAR BOOT LID NOT OPERATIONAL. TRIED USING.MY KEYS AND ALSO THE DASH BUTTON BUT THE GATE WONT OPEN OR CLOSE. HAD TO OPEN FRON THE WINDOW TO LOAD MY SHOPPING. ON MY WAY ON FREE WAY, THE DOOR OPENED AND LOST A BIT OF MY BOTTLED STUFF AND SHOPPING AS IT TOSSED AWAY. SO LUCKY TO BE ON A LINE WITH LIMITED TRAFFIC . HAD NO ACCIDENT

THE DOOR LOCK ACTUATOR FAILED ON THE DRIVERS DOOR. WITHIN TWO MONTHS ALL OF THE ACTUATOR DOOR LOCKS FAILED ON ALL OF THE DOORS. THE COST TO REPAIR IS VERY EXPENSIVE FOR A FIX AND FROM WHAT I HAVE BEEN READING THEY MAY FAIL AGAIN. THIS SHOULD HAVE BEEN RECALLED SINCE THERE WERE MANY OTHER PEOPLE WITH THE SAME COMPLAINT.

THE LOCKING MECHANISM FOR THE REAR GATE REMAINS IN THE LOCKED POSITION WHICH KEEPS THE HATCH UNABLE TO ENGAGE ALLOWING THE GATE TO FLY OPEN WHEN DRIVING. THIS CAUSES A DANGER TO PETS AND MATERIAL STORED IN THE REAR OF THE 2015 HIGHLANDER ON A CITY STREET WHILE MOVING IN A STRAGHT LINE..

WHILE DRIVING, THE RADIO AND MAPPING SYSTEM WILL SUDDENLY STOP WORKING. THERE THEN IS NO WAY TO RESET THE MAP AND/OR RADIO, OTHER THAN TO STOP THE VEHICLE, TURN IT OFF AND THEN RESTART IT. SOMETIMES, IT TAKES MORE THAN ONE RESTART TO HAVE THE SYSTEM BACK TO RUNNING NORMAL. THIS HAPPENS WHEN THE VEHICLE IS IN MOTION AND ON VARIOUS TYPES OF ROADWAYS OR HIGHWAYS. IT HAS HAPPENED ON VARIOUS DATES, BUT THE MOST RECENT OCCURRENCE WAS ON AUG. 10, 2019.

VEHICLE'S RADIO, MAPS, ENTUNES, WILL FREEZE. AS WELL AS THE NAVIGATION SYSTEM. IT WILL THEN RESET ITSELF AFTER A FEW MINUTES OF BEING FROZEN AND UNABLE TO USE ANY FEATURES. THIS OCCURS SEVERAL TIMES A DAY WHILE DRIVING. THIS HAS OCCURRED MANY TIMES A WEEK OVER THE LAST SEVERAL MONTHS.

DRIVER-SIDE DOOR DOES NOT LOCK/UNLOCK WHEN USING THE KEY FOB, DOOR HANDLE, OR THE SWITCH INSIDE THE VEHICLE. ISSUE WAS SPORADIC AT FIRST BUT NOW OCCURS ALMOST EVERY TIME WE (TRY TO) LOCK/UNLOCK THE DOORS. I BELIEVE THE ISSUE TO BE THE DOOR LOCK ACTUATOR, WHICH I INTEND ON REPLACING.
