2014 Toyota Highlander problems

“The radio keeps freezing up all the time along with the back tail light area going in and out. I keep smelling like burnt wire smell. Engine sound really rough.”

“The driver’s-side rear spoiler on my 2014 Toyota Highlander Limited AWD has melted, bubbled, and warped. The vehicle has been stored 100% of the time in a fully enclosed garage with no windows since new. It has only 65,000 miles and has received all service exclusively at authorized Toyota dealerships. There has been no direct sun exposure, accident, or misuse. Toyota dealer and Corporate attributed this to “solar convergence” and denied any repair assistance or goodwill coverage. This explanation does not match the facts given the garage setup and minimal outdoor time. This appears to be a materials/design defect in the black plastic spoiler. Similar melting/warping issues are reported by other owners on Highlanders and RAV4s, even on low-mileage garaged vehicles. Dealer replacement quotes are typically $2,700+. I request NHTSA investigate this recurring plastic failure as a potential defect in materials and workmanship.

“Transmission failing beginning at 60,000 miles. Safety issue because car shudders and refuses to accelerate at seemingly random times. My mechanic said this is a known issue and recommended transmission flushing. We've been doing this for six years at lesser and lesser intervals before the problem reappears. Our local Toyota dealership said they've never heard of the problem but it is reported on numerous automotive forums.”

“On or about 12-01-2022 the windshield wipers stopped functioning. The result was an inability to drive the car in the rain and especially at night. It was impossible to see so we pulled over and waited for the rain to stop. After analyzing the issue the motor had failed. We contacted Toyota for a replacement motor. What we found: No wiper motors are available from Toyota, no aftermarket parts are available. We ordered a motor from Gladstone Toyota but after a couple of weeks began calling. What I was told: no wiper motors are available and there is no release date for when they will be. I began calling around and found that some dealers (TRD Shop) have over 200 on back order and only 80 were released last time they made them. where we are today: We have a vehicle made by Toyota that is unsafe to operate due to the fact the wipers don't work We replaced the wiper switch $232.00 but that only allowed the rear wipers to function further inspection verified the front wiper motor failed in conjunction with the switch that controls the rear wipers. I contacted Toyota engagement center and reported the issues. case #230106000756 they told us they would have a parts…”

“I WAS T BONED ON PASSENGER SIDE, SIDE IMPACT AIR BAG DID NOT DEPLOY. I WAS PUSHED INTO ONCOMING TRAFFIC, FRONT AIRBAGS DID NOT DEPLOY IN HEAD ON COLLISION. SEAT BELT DID NOT TIGHTEN- I INITIALLY HIT DRIVERS SIDE WINDOW, WHEN T-BONED, THEN WITH FRONT IMPACT HIT STEERING WHEEL, ROOF AND CENTER CONSOLE. *TT *TR”

“ON CITY STREET DRIVING ABOUT 37 MPH. ADAPTIVE SPEED CONTROL ENGAGED. I APPROACH A CAR GOING THE SAME DIRECTION SLIGHTLY SLOWER, ABOUT 35 MPH. THAT SLOWER CAR IS FOLLOWING ANOTHER CAR ABOUT 2 CAR LENGTHS IN FRONT. MY CAR GENTLY BREAKS TO BRING MY SPEED BACK TO 35 MPH. MY 35 MPH IS BEING MAINTAINED AT A FIXED DISTANCE FROM THE CAR IN FRONT OF ME. THE CAR DIRECTLY IN FRONT OF ME CHANGES LANE OPENING UP A GAP OF ABOUT 3-4 CAR LENGTHS TO THE CAR IN FRONT OF ME. MY CAR NOW SPEEDS UP AGGRESSIVELY BECAUSE THERE IS NO CAR DIRECTLY IN FRONT OF ME. INSTEAD OF BREAKING WHEN MY CAR GETS CLOSER TO THE REAR END OF THE CAR NOW THAT I AM APPROACHING, MY CAR CONTINUES AGGRESSIVE ACCELERATION TOWARD THE REAR OF THAT CAR. MY CAR WOULD SURELY SMASH INTO THE REAR OF THAT CAR IF I DON'T BRAKE SIGNIFICANTLY. THIS HAS HAPPENED SEVERAL TIMES THROUGH THE YEARS ALTHOUGH NOT FREQUENTLY GIVEN THE CONDITIONS NEEDED TO EXPERIENCE THE FAULT. I BELIEVE IT IS REPEATABLE AND SUGGESTIVE OF A SOFTWARE ISSUE. ALL THE HARDWARE ELEMENTS SEEM TO BE WORKING JUST FINE.”
