Owner reports

Selected complaints filed with NHTSA by 2019 Toyota Highlander owners, lightly cleaned up (personal details are redacted by NHTSA).

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.

I had just driven up a steep driveway and made a slightly sharper than 90 degree turn at a very low speed to pull into a home parking spot when the car lunged forward suddenly and slammed into the stone wall of the house at a high speed. The section of this driveway after the turn is only 2.5 car lengths, but the car picked up enough speed to smash the front of the car in. The car was totaled and driver and side curtain airbags all deployed. I do not know why this happened as there is no way I would have hit the gas hard while pulling up to a building to stop. I also would not have slammed on the gas thinking it was the brake since there would have been no reason to slam on the brake when I was only going 5-10 miles per hour max around the tight turn. My shoe was not caught on a pedal, both sandals were still on my feet after the accident. I am not a two footed driver. …

This is the second time this year 2025 my Toyota Highlander 2019 stalled fist in the middle of of intersection and second on the drive thru in in&out. Suddenly my car died. Tried to turn on followed the on screen instructions but the car failed to turn on. The first time it happened in the middle of the intersection while waiting for the light to change, after the issue I when straight to a car shop and oreilly they have this machine to check any possible issues and he said nothing shows in his machine but he think it's the battery but I told the guy my battery and on the car shop Midas same result no major issue found and one of the technicians says It could be the auto shot off features, that must be manually turn off since this will automatically turn on. …

I am filing this safety complaint regarding a known defect in my 2019 Toyota Highlander Hybrid related to the high-pressure fuel system. My vehicle triggered a Check Engine Light with Diagnostic Trouble Code P107B - Fuel Rail Pressure Sensor 'B' Circuit Range/Performance. This code appeared multiple times (3 stored faults). Toyota has formally acknowledged this defect by issuing Technical Service Bulletin T-SB-0050-20 specifically for 2018-2019 Highlander Hybrid vehicles. This is a fuel system pressure issue that directly affects the safe and reliable operation of the vehicle. …

I was driving my car on a major intersection. The light turned green and I proceeded to make a left turn onto a major street. As I made it onto the street a warning came up that said "Hybrid system malfunction" and my car immediately started decelerating even though I had the gas pushed. I was able to sway to the right into a parking lot and stop the car before it stopped. My daughter was in the back seat at the time when the car failed and since we were in the middle of accelerating to get onto the major street when the car started decelerating, the cars behind me had to hit brakes/change lanes. I had the car towed to the closest Toyota dealership. They diagnosed it as a failed fuel pump. I looked up the issue and saw that Toyota had a recall on fuel pumps. I told them I wanted the improved fuel pump replacement. …

Was stuck in traffic on a highway for about 25 minutes going 0 miles per hour because of an accident about 5 miles away. Then the traffic started to clear and began driving on the road again. About five minutes later, the vehicle lost full drive abilities and the check engine light came on, traction control light on, brake light was on, ABS light was on, stability control warning light on, and then on the info screen the vehicle stated, "Hybrid System Malfunction Stop in a Safe Place, See Owner's Manual", screen then showed within 2-seconds, "Pre-Collision System Malfunction Visit Your Dealer", then in about 2 additional seconds later the info screen stated, "Check Engine Visit Your Dealer", then most every waring light turned on, and there was no power for drive with either hybrid or gasoline engine. …

In the morning of 6/15/2021 while driving the 2019 Toyota Highlander Hybrid in 90+ degree heat on a busy Denver suburb thoroughfare, the Denso fuel pump failed causing multiple malfunction messages to be displayed and the engine to stall placing the SUV and me in a very unsafe situation in traffic. The SUV was partially in traffic because a curb prevented me from driving the vehicle out of traffic and the fail safe mode did not allow me to drive to a cross street to get the SUV out of traffic. Fortunately, a police squad arrived, parked behind me with emergency lights flashing until the tow truck arrived. The SUV was taken to a nearby Toyota dealer where Toyota service personnel in conjunction with Toyota engineering determined the Denso fuel pump was the problem and was replaced. Toyota has the Denso fuel pump. …

We purchased our brand new Toyota from the dealership in July of 2019. We used the dealership for every scheduled maintenance and maintained updated contact information the whole time. On August 6, 2021 when we were approximately 100 miles from home our car stalled abruptly in the middle of an intersection. The car was not driveable so we called a tow truck and we're able to obtain a rental car. The car was towed to the nearest dealership which informed us the problem was due to a recalled faulty fuel pump. ( The first we had ever heard of the recall) The dealership fixed the car free of charge but denied us twice when we asked for approximately $450. 00 in reimbursement charges for the tow truck and car rental. We finally received a notice concerning the very long ongoing recall on or about September 2, 2021. …

On occasion I have been walking around this car while its just parked in my garage and I hear a a humming sound like a electric gas pump. This is 4 hours after it was used last. It is a faint sound coming from the the rear seating area. Just before I started to write this I went out to check it again and its not doing it. This is not a one time event and its concerning since I believe its electric and may be involved with gas in a parked garage. The vehicle is in like new condition and had one minor cosmetic type accident while in its first year of use. Scratches to driver side panels and front bumper. I will call the dealer tomorrow to see what they have to say. Thanks in advance for any info you can share on this issue, a fire in my garage would bad.

My car continues to stall/become powerless while driving even after replacing the low-pressure fuel pump as part of the earlier safety recall On Oct/28 2021by the dealer. The same problem started re-occurring once two weeks ago and again twice today while driving on busy road. It is a safety issue, my car has driven only 17k miles. I have visited the dealer last week and reported the issue and requested to check the fault code and ascertain the fault. They have expressed their inability to do it and said, the car is out of warranty. I think the problem is beyond the fuel pump or the work was not done in a proper workmanship manner.
