Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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

“I am submitting this complaint to report a significant safety defect in my Lexus vehicle.

This unexpected loss of power created an immediate and substantial risk of a collision and posed a serious danger to myself and other motorists. …”
