IllustrationMy 2026 Toyota Grand Highlander XLE has a recurring gasoline smell near the rear driver’s side after long trips or when parked with the engine idling. The source of the odor and the specific component involved are unknown. I am concerned about a possible fuel or vapor leak and the potential fire risk to myself and my passengers.

Failed System: Fuel Injector Failure (?) at high speeds, under load (uphill), causing an immediate and life threatening loss of power. While traveling on the highway, going up mountainous areas, the vehicle loses power and shakes violently. During multiple repairs/visits, the dealerships state that it is the failure of fuel injectors. They are replaced, and it happens again with the same explanation. Safety: Three times my family has lost power at 70mph while traveling uphill surrounded by many cars. The last event ended in a a scary and close interaction with an 18 wheel truck that was unable to stop as we lost power. Dealer Confirmation: The dealer has confirmed, on two separate occasions, that the fuel injectors needed replaced. The vehicle has 3,000 miles on it. At 2,000 miles, damage was found to the fuel injectors. They were replaced and the car was placed back in my possession. At 3,000 miles, the incident occurred for the 3rd time and damage was again found with the fuel injectors. Inspection: Dealerships as well as Toyota's field technician have inspected/repaired the vehicle 2 times and is currently at a dealership for the 3rd time. Warning messages: After the incident occurs, multiple warning lights appear (check engine and hybrid system malfunction).

1DP26006 · Road Debris/rocks Damaging The Heat Exchangers
Opened Aug 20, 2026 · No close date supplied
Status: open (inferred from source dates) · Engine And Engine Cooling:cooling System
The Office of Defects Investigation (ODI) received a Petition dated July 20, 2026. The Petition requests an investigation of road debris / rocks damaging the heat exchangers in model year (MY) 2024-2026 Toyota Grand Highlander vehicles. The Petition contends that the Grand Highlander’s front-end grill has large, open apertures and no protective screen between the grill and the vehicle’s heat exchangers. The Petition further alleges that as a result, during normal driving, the damage to heat exchangers results in coolant leakage and sudden loss of propulsion. The Petitioner cites thirteen (13) complaints received by ODI alleging this failure, which, when added to the petitioner’s own complaint, bring the total under consideration at this time to fourteen (14). ODI will evaluate these complaints to determine if they are related to the failure cited in the Petition and conduct a technical review under 49 CFR Part 552. This Defect Petition is being opened to evaluate whether to grant or deny the petition. The petition can be reviewed at NHTSA.gov under ODI number 11754975.
