2015 Toyota Highlander electrical system problems

“The a/c condenser was damaged due to impact of road debris. This caused loss of proper system operation. The cost to repair was $1100+. The debris entered thru the front grill, which has nothing in place to prevent debris from entering the engine compartment.”

“The contact owns a 2015 Toyota Highlander. The contact stated that the power liftgate consistently failed halfway through while opening and closing the liftgate. The vehicle was not taken to the dealer. The vehicle was not diagnosed or repaired. The contact became aware of information online about Technical Service Bulletin: SB0023/16, NHTSA ID Number: 10134306 (Structure, Electrical System); and associated the failure with the TSB. The manufacturer was made aware of the issue and confirmed that the vehicle was not covered under warranty, TSB, or a recall. The failure mileage was approximately 133,000.”

“The contact owns a 2015 Toyota Highlander. The contact stated that while driving on several occasions at various speeds, the infotainment screen would go blank and the system would turn on inadvertently. This issue became more frequent, occurring approximately every 10 seconds. The power steering warning light also illuminated. The vehicle was taken to an auto parts store where a handheld diagnostic machine did not detect any failures or codes. The contact stated that while driving on several occasions at various speeds, the steering wheel became extremely stiff. On one occasion while his daughter was driving and turning the vehicle on a curved road, the vehicle veered into oncoming traffic. The contact stated that she managed to get the vehicle back to the correct side of the road, then stopped and inspected the vehicle. The vehicle was then taken to an auto parts store where a handheld diagnostic machine was used, but the failure was not detected. The vehicle was not diagnosed or repaired. The contact believes that the steering failure was associated with NHTSA Campaign Number: 15V144 (Steering). The manufacturer was notified of the failure. The failure…”

“Door lock actuators, yes it is available for inspection. Doors cannot be locked or unlocked with a remote key fob or the interior power door locks. Lock defect poses a significant safety hazard in that a single or multiple doors may not lock at any time, whether the vehicle is on or off and despite actions or commands by the driver. The alleged defect is dangerous to passengers as it can cause unintentional door openings while a vehicle is in use, result in inoperable doors during emergency situations, and leave a vehicle and any contents therein more vulnerable to theft. This poses serious safety concerns, for example when vehicles are involved in vehicular accidents because the occupants may become entrapped when the Door Actuator Defect prevents an occupant from unlocking the doors. Furthermore, this defect jeopardizes the safety of vehicle occupants given that not all doors are capable of being manually unlocked from the exterior. Since owning my highlander I've taken it to the dealership several times for this issue. The front door driver and passenger were replaced and a lock switch however dealership claimed they could not recreate the issue for all…”

“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.”

“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…”
