Fuel system: “My car is going into limp mode/ reduced power and I am having misfires on cylinders 3 and 4. I’ve replaced my fuel injectors, spark plugs and catalytic converter.

NHTSA complaint #11752947, filed 2026-07

Engine: “I am writing to formally express my concern regarding ongoing issues with my vehicle following repairs performed at Crown Lexus in Ontario. In December 2024, I experienced rough idling, slow acceleration with vibration, fluctuating RPMs, and stalling. The check engine light turned on, and an error message instructed me to pull over and contact a local dealer due to engine/transmission trouble. I promptly brought the vehicle to Crown Lexus, where it was diagnosed with a faulty cylinder head requiring full replacement. The repairs were completed at that time. …”

NHTSA complaint #11660901, filed 2025-05

Transmission and drivetrain: “I am submitting this complaint to report a significant safety defect in my Lexus vehicle. Without any prior warning or history of mechanical problems, the vehicle experienced a sudden and severe loss of engine power while I was merging onto a busy highway. The vehicle rapidly decelerated despite continued acceleration input, forcing me to navigate to the shoulder while surrounding traffic was traveling at high speed. This unexpected loss of power created an immediate and substantial risk of a collision and posed a serious danger to myself and other motorists. …”

The brake pedal was depressed but the vehicle did not reduce in speed. The contact crashed into a side tree, columns, and a divider in order to stop the vehicle.
