2023 Lexus RX

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.

I WAS DRIVING AND MY SUNROOF EXPLODED FROM THE INSIDE. GLASS WAS FACING UP AND THERE IS NO VISIBLE SIGN OF ANYTHING HITING THE SUNROOF FROM ABOVE

[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.

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.

2023 Lexus RX350. Subscription expiration caused a total screen freeze that prevent other functions ( i.e. rear view camara) to work as the screen just go blank and hang forever unless you reboot. Big safety issue!

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.

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.

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.

If we don't drive the car for 4 or 5 days, especially in cold weather, the car will sometimes not start due to a drained 12V battery. We've spoken to Lexus of Rockville, MD and Lexus roadside assistance, who are aware of the issue but say the 12V battery is "healthy." Online research shows this is a widespread known issue with Lexus RX350h and RX500h vehicles from 2023 onward: [XXX] [XXX] . A simple software update to ensure that the high-voltage hybrid battery charges the 12V battery to a greater extent when the vehicle is parked should solve the problem, but Lexus has so far not addressed this problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Hi. I noticed my vehicle was randomly making a clunking noise in the rear end. Also, on the highway, it would drift and was difficult to steer. I took it to dealership to be examined because it was still under warranty. They showed me that the driver's side rear trailing arm was disconnected. The bolt was not even there. They stated that it was caused by outside influence, possibly from hitting something. But I did not hit anything. The only sign of damage was where the loose trailing arm rubbed against the steering knuckle. They also told me it was too dangerous to drive off the lot. Because they claimed outside influence, they did not cover it under warranty. I took it to my mechanic. He believed the bolt had come loose on its own. He thought this because the trailing arm bolt on the passenger side was very loose and about to fall out. The mechanic replaced the missing bolt and tightened the loose bolt. I would like to document that this happened and see if any other people had reported this problem. Lexus denied that there was an issue.

On at least 7 occasions the driver was TRAPPED inside the vehicle. The car failed to start and the doors and windows locked. If the driver had not had a cell phone to make an emergency call he would have been locked inside until someone discovered the problem. Had this happened in Phoenix, AZ in the summer, there is a very good chance the driver would have been dead before he was rescued. The last time was December 11, 2025. We replaced the starter battery for 2nd time in 2 years and 40K miles.

My electronic door handles fail when there is frost and or cold weather

The car battery goes dead when car not used in 14days, or not driven on freeway long enough to top off battery. We've had to jump it for being in a cool garage for a couple of days, and the battery is only 2yrs old. The car needs a stronger battery.

I entered then attempted to start my Lexus on November 11, 2025. The car would not start - the dashboard lights fleshed briefly, then the car was completely dead. There was not a light on anywhere. The doors would not open and the windows would not roll down. I was trapped. fortunately I had my cell phone so I was able to call my wife who was inside of our house. She could not open the door with the manual key, She called AAA. The tech hooked up some power device under the hood and the car started and seems OK. This was frightening. I was trapped in the car and running out of air. I could have suffocated.

While we were driving, our sunroof just exploded! There was no-one around us. There was a loud bang, glass was flying and the wind was so loud we couldn't hear each other. If my wife would have been driving, we probably would have wrecked because she screamed and through her arms in the air. We exited off the road, inspected our vehicle and took pictures. The only damage we could see was the front section of our sunroof was shattered. We drove to the nearest dealership where they took pictures and ordered a new sunroof. I might add they couldn't guarantee the replacement would be under warranty, which I find shocking. My wife and I are on vacation and we had to leave our car in another state along the way and rent a car.

Spontaneous sunroof glass burst

When removing foot from gas pedal the rpm shoot up to almost 4k instead of switching to EV mode or dropping to 1k rpm’s. This has scared my wife causing her to slam on brakes as she thought throttle was stuck since the rpm’s shot up. This is dangerous. It doesn’t happen all the time and Lexus did duplicate it but said was normal.

My air bags did not deploy with a head on collision.
