2019 Toyota Highlander fuel system problems

Filed Oct 21, 2026 · Engine, Fuel system · GA

My husband was driving my car out of town, and while driving approximately 70 mph, my car stopped going. When he pressed the gas pedal, the engine revved, but did not move forward. He had to coast down the interstate and pull over on the side of the road. He said he almost got tear ended by a semi-truck. I called roadside assistance through my insurance company and it took them 2.5 hours to get to us. We had to have it towed about 70 miles to a shop and pay $184.00. The body shop we towed it to said it is the transmission. He said he knew it to be a common issue with 2019 Toyota Highlanders. I looked it up online and found several instances of similar stories. There was no warning.

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.

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.

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. The second incident in In&Out the car died suddenly, tried to turn the car but it was on Drive so change to stop then tried to turn on multiple times but faulted , the crews decided to help us push the car out of the drive thru since we are blocking all the customers car, the steering wheel so stiff could hardly turn. We can’t change gear from stop, I was told to push off and on manual break foot pedal and this this help able to change gear to neutral, so we can push the car out of the drive thru. No message or failure message in the screen. We just push the car in the parking lot. Tried to turn on but failed. One of in&out staff was so kind to help us, he has a portable jumpstart and the car able to start. Able to drive home safe. Now I’m afraid to turn on my car or drive far distance due to this issues.
