2023 LEXUS RX — Problems, Recalls & Safety Data

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.

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.

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.

I took my vehicle to Lexus of Louisville on 2/2/26 for Recall campaign number: NHTSA 25V744000 (Lexus internal 25LB06. My backup camera does not work at all but I was told my vin is not part of the recall even though my year, make and model is. Lexus charged $250 to diagnose the problem and the repair is $1311 for a new camera. The part is on backorder. I drive on average 25,000 miles per year. Not having a back up camera is a safety risk for myself and everyone around me as I am in and out of a minimum of 12 parking lots per day. My service rep, John said to diagnose the issue they replaced my camera with another one on the lot to confirm that was the issue. I have attached pictures of the problem. I do not believe this is a coincidence and hope Lexus will stand up and recognize the larger issue here.

The 2023 Lexus RX-350 has had complete 12 volt battery failure twice in the last year. The hybrid battery charging procedure for the 12 volt battery is insufficient. Twice I have been stranded. The frequency and duration of the hybrid battery charging is not sufficient. A more powerful 12 volt AGM battery is needed. The dealer says I am not taking sufficiently long trips to charge the battery. Last Saturday I took two 30 - 40 minute trips but the battery had only 11.8 volts requiring a 100% charge. There should be a recall to fix this problem.
