2019 Toyota Highlander Engine Problems

Bought car in April 2025. Has 80,000 miles. Transmission failed.

In early January 2026 there was rough/delayed shifting, whining noises, and fluid leaks. Probably linked to the faulty UA80E/F transmission type. The check engine light came on 1/15/26, I took it into a local repair shop. The mechanic flushed and changed the transmission fluid, replaced all of the spark plugs and the serpentine belt. I picked it up on 1/16/26. There was still shuddering, strange sounds (whining/grinding), and hesitation. On 1/20/26 I drove it and the rough/delayed shifting, whining noises, hesitation and burning smell started happening. The car completely broke down on the freeway and wouldn't drive at all. I had to slowly pull over to the shoulder of the freeway and have the car towed to the repair shop. They inspected it and said I need a new transmission, and it cannot be fixed. I believe the next steps are to have it towed to the toyota dealership to have it looked at.

Initially had issues with acceleration with RPM’s going high with car moving very slowly. Five days after that started, car broke down 3 times in one trip & would not drive or go in reverse. Per dealership, the car needs a new transmission even though it’s only a 2019 with 110,000 miles.

The contact owns a 2019 Toyota Highlander. The contact stated that while driving on several occasions at various speeds, the contact heard abnormal buzzing sounds coming from underneath the vehicle. The vehicle was taken to a dealer; however, the failure could not able to be replicated. The contact stated that a day or two days later, while stopped at an intersection, and attempting to accelerate, the vehicle failed to accelerate as intended. There were no warning lights illuminated. The vehicle was pulled over to the side of the road and restarted; however, the failure persisted. The vehicle was towed to a dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 59,000.

Started noticing a whining noise when accelerating. This appears to be drive shaft/transmission issue. Was quoted 7k to remove and replace. This should be an active recall for this issue what is Toyota doing?

Our 2019 Toyota Highlander currently has 54,605 miles. In August 2025, when the vehicle had 50,236 miles, we brought it to the Toyota dealership to address a whining noise coming from the transmission. At that time, the vehicle was still under the manufacturer’s warranty. The dealership performed a transmission service during that visit. Within the following weeks, however, the whining noise returned, and the vehicle began experiencing hard and delayed shifting. Our children and grandchildren have recently moved to Washington, and we had planned to drive there to visit them. Unfortunately, we are now reluctant to drive the vehicle due to safety concerns, as we have been advised that the transmission may be failing. The dealership has now recommended a full transmission replacement. Because the original concern was reported while the vehicle was still under warranty, we believe the issue should have been properly diagnosed and resolved at that time. However, the problem was not addressed, and the vehicle is now outside the warranty period, with Toyota declining to cover the cost of the replacement transmission. Given that the problem was first reported while the vehicle was under warranty, we are requesting that Toyota reconsider covering the transmission repair or replacement.

Whining sound when when pushing the gas to accelerate. When you let go of the gas it stops.

During the incident, several warning messages were activated which included the check engine light and the ABS warning. While inspecting the vehicle smoke and fire began to stream from under the engine hood and moments later the frontend of the vehicle became engulfed in flames. The fire department was called to the scene and extinguished the flames. During the incident, the vehicle was destroyed and later towed away. A police report was taken at the scene. The cause of the failure was not determined. The manufacturer was notified of the failure. The local dealer was not contacted. The failure mileage was 96,200.

Experience "dead zones" in accelerator pedal movement. Experience "no acceleration" with first 1-2 inches of travel from idle position. This is constant and does not vary noticibly with speed. I was driving in an suburban shopping area in York PA with three lanes of travel in each direction. I intended to move from the laft hand lane to the center lane. I indicated my intentions and waited for an opening. I was travelling about 35-40mph. When an opening came along, I steered into the indended lane, but depressing the accelerator to increase my speed, no acceleration occurred. I then panicked and depressed the pedal quicker, and the ensuing acceleration nearly catapaulted me into the semi truck in the center lane ahead of me. I missed the truck by inches. I have had this issue evaluated at Bennett Toyota in Lebanon PA, and the Lancaster Toyota, the dealer who sold me the vehicle in May of 2023, is aware of the issue. Bennett Toyota service department tried to fix the issue by replacing the brake switch. That did not alleviate the problem. I have had several other instances when pulling into traffic when the delayed acceleration caused me issues but no accidents. I believe this issue is related to the selectable "snow" driving function. I think the system is somehow stuck in the "snow" mode at all times. I may have substantiated this today when I experimented with the "snow" function while driving at about 45 mph. When I select the "snow" mode while driving, the accelerator "dead zone" actually gets worse. Bennett Toyota Service response is "it drives like any other Highlander". If that is so - this is truly a huge issue with "drive by wire" tachnology...!!! As a note, at Bennett Toyota I did drive a 2019 Highlander privately owned by the service manager and it did indeed have the dead zone in the acelerator - a fact that the service manager admitted to me verbally. I have read many instances of this issue in chats online.

The contact stated while his wife was driving in a parking lot at approximately 2 MPH, the vehicle suddenly accelerated without the contact's wife having depressed the accelerator pedal. The vehicle crashed into a railing in the garage. The contact stated his wife had not noticed any warning lights. The vehicle had minor damage to the front grill and bumper there were scrapes and dents on the driver's side front fender and also to the passenger side front fender. The vehicle was drivable. The contact drove the vehicle to a local dealer, the vehicle had not been diagnosed. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 40,000.

Battery constantly keeps dying. I have already bought two new batteries. I have been stranded because my car would not start. For no reason and never know when it will happen but battery will drain and not crank

Driving under "normal" weather conditions when the check engine light warning along with the hybrid maintenance warning light. The car stalled while trying to safely pull to the side of the road. The vehicle was towed to the nearest Toyota dealership. They confirmed fuel pressure codes p0087, p107b, p3190. I was told Toyota has not issued any updates for this problem. So I am stuck with a car that isn't safe to drive, especially long distances.

My vehicle was not part of the fuel pump recall like the other 3.3M vehicles from Toyota. However, my vehicle exhibited the exact same symptoms as those cars and stranded me on the side of the road twice. This included pushing on the accelerator and getting no response from the car followed by numerous system warning lights including hybrid system malfunction, front collision system failure, and check engine light. Initially, the dealership could not find anything wrong when I first brought it to them. The second time it happened, I was able to bring the car in with the check engine light still on so they were able to diagnose it and are currently replacing the fuel pump. My car (and many others) should have been included in this recall, this is a huge safety issue as this had me stranded on the side of very busy highways twice plus not being able to accelerate in traffic.

ALTHOUGH MY CAR WAS NEW (ONLY 11 MONTHS OLD) AND LESS THAN 5000 MILES, IT HAD SHUT DOWN COMPLETELY WHILE I WAS PULLING OUT OF A PARKING LOT. I HAD TO GET IT TOWED TO THE NEAREST TOYOTA DEALERSHIP OVERNIGHT. THEY TOLD ME IT WAS MY FAULTY FUEL PUMP AND THAT THEY HAD NEVER SEEN THAT HAPPEN TO SUCH A NEW CAR BEFORE. CURRENTLY I HAVE MY CHECK ENGINE LIGHT ON (MY CAR HAS LESS THAN 6200 MILES ON IT) AND IT ONLY GOES AWAY WHEN I PUT IN A FULL TANK OF GAS. AFTER I DRIVE ABOUT 2 MILES, THE CHECK ENGINE LIGHT TURNS ON AGAIN. I AM TERRIFIED MY CAR ENGINE WILL JUST DIE ONCE I'M ON THE ROAD, OR WORSE, THE FREEWAY. I AM UNABLE TO DRIVE THIS CAR WITHOUT THAT FEAR. PLEASE SEE CULVER CITY TOYOTA RECORDS FOR PROOF OF MY FUEL PUMP PROBLEM AND ENGINE DYING. THEY ALSO HAVE RECORD OF MY TOWING TO THAT DEALERSHIP THE NEXT DAY ON SEPT 1, 2020.

TWICE MY VEHICLE HAS DIED IN TRAFFIC. FORTUNATELY I WAS ON SURFACE STREETS AND NOT A FREEWAY. BOTH TIMES I HAD TO PHYSICALLY PUSH IT INTO A PARKING LOT.

WHEN ACCELERATING FROM A STOP, THE CAR ABRUPTLY LOST POWER AND IT FELT LIKE THE ENGINE WAS GOING TO STALL OUT COMPLETELY, BUT THEN THE CAR STARTED ACCELERATING AGAIN. THIS HAPPENED THREE TIME TODAY. IN TWO CASES I WAS NEEDING TO ACCELERATE BRISKLY AS I WAS EITHER CROSSING, OR ENTERING ONTO, A BUSY STREET WITH FAST TRAFFIC. IN TWO CASES (IN BOTH CASES I WAS MAKING A RIGHT TURN FROM A STOP) THE RED EXCLAMATION POINT WARNING SIGN APPEARED BRIEFLY ON THE DASH BOARD UPPER SCREEN. ON THE THIRD OCCASION (I WAS ACCELERATING STRAIGHT AHEAD FROM A STOP), A RED WRITTEN MESSAGE APPEARED ON THE CENTER DASH BOARD SCREEN, BUT IT DISAPPEARED BEFORE I COULD READ IT.

MY VEHICLE HAS BEEN RUMBLING AND THE CHECK ENGINE LIGHT ON. A DEALER TURNED IT OFF VIA RESET, BUT THE CAR IS STILL ACTING UP. WE JUST GOT A NOTICE FROM TOYOTA THAT THE VEHICLE IS AT RISK OF STALLING UNEXPECTEDLY AND WITH NO REMEDY FOR OVER A MONTH.

FUEL PUMP STOPS WORKING WHILE DRIVING ON HIGHWAY AT HIGH SPEEDS, VEHICLE RIDES ROUGH INTERMITTENTLY THEN SHUTS DOWN. VEHICLE WILL NOT START UP AGAIN.
