Open the full vehicle complaint log (all categories)The vehicle has exhibited intermittent drivability and safety-related concerns after a prior collision repair. The concerns include delayed acceleration/engagement, abnormal jerking or stopping behavior, and elevated RPM behavior during real-world driving. The most recent documented event occurred on July 27, 2026, while the vehicle was in Drive at approximately 50 mph with cruise/driver-assist indicators illuminated. The tachometer appeared near the 4,000 RPM range. The event was captured by video/screenshot and the vehicle is available for inspection upon request. The issue creates a safety concern because delayed acceleration, unexpected jerking/stopping, or abnormal RPM behavior could affect the driver’s ability to safely merge, maintain speed, respond to traffic, or control the vehicle during highway or road driving. The problem has been intermittent and has not always produced an active warning lamp. A Lexus dealer inspected/scanned the vehicle on May 21, 2026 and discussed Eco Mode/Normal Drive Mode, but the symptoms continued afterward. The vehicle has a documented post-repair history involving transmission cooler replacement, transmission-fluid concerns, and prior transmission/powertrain/electronic-control diagnostic code history. Lexus Brand Engagement has also been notified under an active case, but there is currently no clear authorized Lexus repair path. The exact failed component is UNKNOWN. Based on the symptoms and repair history, the concern may involve the power train, speed control, electrical/electronic control system, or related driver-assistance systems.
The vehicle hesitates with apparent gear dragging and audible whining or grinding noises. The condition worsens when driving uphill and includes occasional sudden increases to high RPMs during normal acceleration. A slight burning odor is sometimes present after driving, along with lower-than-expected fuel economy in city and highway driving. The transmission exhibits harsh shifting, hesitation, and loss of smooth acceleration, negatively affecting drivability and raising safety concerns. Dealer inspections have not resolved the issue and claim the condition is normal.
