Vehicle engine is running rough and threatened to stall in traffic due to a failed low-pressure fuel pump. This model year is under a major fuel pump recall, but my VIN was excluded. The gauge isn't reading correctly either

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. A failure in the fuel rail pressure system can cause: •Sudden loss of engine power while driving •Unexpected stalling at highway speeds •Inability to accelerate when needed, creating a dangerous situation in traffic Despite Toyota acknowledging this defect through TSB T-SB-0050-20, Jim Coleman Toyota (10400 Auto Park Ave, Bethesda, MD 20817, Phone: 301‑618‑0480) quoted me nearly $3,000 to repair this issue rather than covering it under warranty. I believe Toyota should issue a formal recall to protect all owners of affected vehicles. I am requesting that the federal safety agency investigate this matter and pressure Toyota to issue a recall covering all 2018-2019 Toyota Highlander Hybrid vehicles affected by this known fuel system defect.

Vehicle has experienced sudden stalling while driving and an intermittent Check Engine Light with Diagnostic Trouble Code (DTC) P107B — Fuel Rail Pressure Sensor “B” Circuit Range/Performance. This is the exact condition covered by Toyota Technical Service Bulletins T-SB-0050-20 and T-SB-009-23, and Customer Support Program 23TE04 (Denso low-pressure fuel pump settlement coverage, valid until July 15, 2036 or 150,000 miles). Timeline: • Late April 2026 (while driving ~300–400 miles from home): Vehicle stalled without warning at a red light. • May 5, 2026 (while driving on freeway ~50–75 miles from home): Check Engine Light illuminated. AutoZone scan and dealer diagnostic tool both confirmed DTC P107B. • May 5, 2026: Dealer performed health check using Toyota GTS+ tool (see attached screenshot taken at 15:58:01). Screen clearly shows “PERMANENT: YES” confirming a permanent stored fault code. • May 5–15, 2026: Crown Toyota (Ontario, CA) confirmed the code was present on arrival (Repair Order 2842115 dated 05/15/26). They later cleared the code, performed a short test drive, could not duplicate the fault at that moment, and closed the repair order as “inconclusive.” They refused the low-pressure fuel pump replacement under Customer Support Program 23TE04 even though corporate cases #260505002096 and #260515002110 had previously confirmed eligibility based on the prior pump replacement (9/11/2021, RO #1764477). The issue is known to be intermittent and occurs under load/highway conditions. This creates a serious safety risk of sudden loss of power while driving. T-SB-0050-20 specifically directs dealers to replace the low-pressure fuel pump assembly when P107B is present on 2018–2019 Highlander Hybrids, and T-SB-009-23 provides the official repair procedure under CSP 23TE04. I have attached: (1) the dealer repair order RO 2842115, and (2) the May 5, 2026 GTS+ diagnostic screenshot showing the permanent DTC. Please investigate this as a potential safety defect.

This vehicle safety complaint is regarding my 2019 Toyota Highlander XLE, VIN [XXX] . A Toyota-authorized dealership, Sansone Toyota in Avenel, New Jersey, documented that the front driver axle is prone to freezing in the differential. This is a serious safety concern because if the axle seizes while the vehicle is in motion, it could cause sudden loss of control. This vehicle is used regularly as our family vehicle, including to transport our family of 6 with our young children. I am extremely concerned about continued operation of the vehicle while this documented condition remains unresolved. In addition to this safety-related axle issue, this vehicle has a broader history of serious mechanical problems. On May 13, 2022, after a recent service visit at DCH Brunswick Toyota, I reported that when I pressed the gas the vehicle was making an unusual noise like an old car, that the car delayed to speed when I pressed the gas, that I had to press the gas all the way in order for the car to move faster, and that it was not like this prior to service. At approximately 25,000 miles, I also asked that the brakes be checked because when we drove the vehicle and used the brakes, the car made a startling sound. In 2023, I also reported hard/heavy steering and jerking while driving. I reported transmission-related abnormal noises and drivability concerns while the vehicle was still within Toyota’s powertrain warranty period, but the condition was not properly diagnosed at that time. The transmission has since been confirmed by authorized Toyota dealerships to require full replacement. The vehicle also has a documented engine oil leak, leaking shock absorber, and prior recall history involving a stalling condition. I've filed this complaint with the federal safety agency due to the axle-related safety risk. Toyota is now on written notice of that condition. Mileage: approximately 101,000 Documenting safety issue: Sansone Toyota, Avenel, NJ Please review this potential safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

At 138,000 miles my 2019 Toyota Highlander's transmission failed. I noticed a whining sound when I pushed on the accelerator, so I scheduled a service appointment to have it looked at. The day I brought it into the mechanic it began stalling at stop signs. I was driving my children to school when the vehicle began stalling, fortunately I was able to get it looked at that day. My local mechanic diagnosed it as a failed transmission having to do with something inside the transmission. I called Toyota and they said in order to qualify for support through their service program I needed to have the vehicle diagnosed by at a Toyota dealership. I had the vehicle towed to the dealership, where they too confirmed the transmission had failed due to something inside the transmission, which they diagnosed with a telescope. They quoted me $12K for a new transmission! I had routine maintenance performed throughout the life of the vehicle, primarily at the Toyota Service Center. Just 20 months prior to this happening I had the suggested transmission services completed at the dealership. The only services I had completed outside of the dealership over the last 20 months were regular oil changes and tires. The transmission in my 2019 Highlander is the same failed transmission as the ones in the 2017-2018, which Toyota issued a bulletin on, the same transmission Toyota has received numerous complaints about. The same transmission with hundreds of other customer's have filed incident reports on. The transmission they knew was problematic yet continued to put into new vehicles. I've been a loyal Toyota customer, this is my 5th Toyota. I can't believe that there is nothing Toyota is willing to do to support their customers. I thought Toyota prides itself on being a trusted brand with loyal customers, because they make vehicles that last and take care of them when they don't. I was wrong.

Check engine light came on without warning, car started losing power, idling roughly, stalling out, and not wanting to start. Had my battery, alternator, and starter checked and they are all fine. Diagnostic test showed it was to do with how much fuel/air the vehicle is getting. The check engine light goes off and on as I’m still having to try and drive my vehicle to and from work due to not having other transportation.

Good Morning, I purchased a 2019 Toyota Highlander at a Toyota dealership and the transmission has died at 68,000. It died while driving in heavy traffic with my kids in the car. Toyota has completed an inspection of the transmission and determined that it needed to be replaced. They also said that because the transmissions are in back order due to all of the failures, I would have to wait 45-60 days to get a remanufactured transmission. I've also heard that they are replacing these transmissions with the same ones that are failing and only offering a 1 year warranty. Ive already spoke with Toyota Brand engagement and they told me that there was nothing that they could do.
