2023 Lexus Rx

I am experiencing ongoing issues with my 2023 Lexus RX500h related to the powertrain/transmission. The vehicle has exhibited abnormal shifting behavior, including hesitation, jerking, and inconsistent acceleration. At times, the vehicle does not respond smoothly when accelerating, which raises safety concerns, especially when merging into traffic or driving at highway speeds. The issue occurs intermittently and has persisted despite multiple attempts to diagnose or address the problem. The condition affects the drivability and reliability of the vehicle and has not been resolved.

Car stopped running during turn. Then started creeping along ,then after a bit ,started working normally. Happened a few times after. Then later car wouldn’t start in garage, had to get jumpstart. Took to Lexus dealer and found out the 12 volt battery was shot.they replaced it. Very frightening experience. Could have had an accident.

The contact owned a 2023 Lexus RX 350. The contact stated that while the vehicle was stopped at a traffic light, it suddenly accelerated without warning. While driving in a parking lot, the vehicle again surged forward approximately 20 feet. The contact was able to swerve to avoid striking a pedestrian. The vehicle became uncontrollable, and the brakes were inoperable. The vehicle ultimately crashed into a dumpster fence, which fell onto the vehicle. The contact sustained injuries to her mouth, including cuts to the inside and outside of her mouth, and medical attention was provided by a plastic surgeon. The fire department responded to the scene. The air bags did not deploy during the crash. There was no fire, and a police report was not filed. The fire department was on the scene. The vehicle was towed to a local dealer; however, the vehicle was not diagnosed or repaired. The insurance company later deemed the vehicle a total loss. The manufacturer has not been notified. The failure occurred at approximately 18,000 miles.

[XXX] ’s my wife we’re driving in Sacramento.The vehicle was stopped at a traffic signal waiting for the light to change. Suddenly, without warning the vehicle started violently shuddering/shaking, scaring us completely. The shaking stopped when my wife put into park. But for those few seconds it was extremely scary. This incident should be investigated by the NHTSA as a repeat of the incident in moving traffic may cause severe property damage, serious injury and possible loss of life. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving westbound on Route 70 in Ohio at highway speed, we suddenly heard what sounded like an explosion and immediately felt exposure to outside air within the vehicle. The event was abrupt and very startling while in motion. After safely stopping and inspecting the vehicle, we observed that the driver-side rear door window had shattered. The damage included a pronounced irregular opening located approximately in the middle of the window toward the rear edge, with complete fragmentation of the surrounding tempered glass. We inspected the interior of the vehicle and surrounding area for evidence of a rock, debris, or other projectile but did not locate any object that could have caused the damage. This unexpected window failure created driver distraction, potential risk of injury from glass fragments, and sudden loss of window integrity while driving at highway speed. This report is submitted so that any potential pattern of unexpected automotive glass failure in this vehicle model can be evaluated.

This submission is a supplement to a previously filed complaint. Original complaint number: 11719553." In my previously submitted complaint, I incorrectly stated that the vehicle remained stationary until delivery. The actual situation is: the sunroof glass shattered while the vehicle was parked, but the day after the incident, I drove the vehicle to the dealer for inspection. I am providing this supplement to clarify the vehicle’s status in the original report. The incident occurred while the vehicle was completely stationary, with no external forces or driving involved.

Vehicle: 2023 Lexus RX350 (Certified Pre-Owned) Ownership Duration: ~3 months Incident Description On February 1, 2026, the sunroof glass of my vehicle shattered inward into the cabin without any collision or known external force. The vehicle was parked on the street next to a residential garage entrance, with no trees or overhead objects nearby. I have photographs documenting the shattered sunroof. No alerts were received on my mobile app at the time. The vehicle remained stationary and was not operated until delivered to the dealership. Around February 2–3, my mobile app indicated vehicle activity, confirming the dealership accessed or connected diagnostic equipment while the vehicle was in their possession. They never disclosed inspection results or technical findings. Dealership and Manufacturer Response February 2, 2026: Vehicle delivered to authorized Lexus dealership; advised to contact manufacturer. February 13, 2026: Lexus North America phone call – warranty/goodwill coverage denied. February 19, 2026: Dealership confirmed repair not covered. Email to service manager requesting inspection findings, diagnostic conclusions, and written denial – no response. February 20, 2026: In-person visit; dealership refused to provide inspection results, stating vehicle was received broken and I could pay for repair or take it unrepaired. Repair Order (R/O) stated: “Probably due to outside influence.” No evidence or technical explanation was provided. Safety Concern The sunroof glass shattered inward, presenting a direct hazard to occupants. The failure occurred within three months of CPO purchase, raising concerns about inspection process and sunroof integrity. This may indicate a broader defect affecting other vehicles with similar sunroof systems. Current Status Vehicle is under repair at my expense despite lack of confirmed cause or documented findings.
