2023 Lexus RX 350 problems

“The transmission is jerking at times and it failed to accelerate at one point after coming to a complete stop. Notified Lexus and still working to fully resolve the issue but they just denied my request to reevaluate the issue.”

“The contact owns a 2023 Lexus RX 500h. The contact stated that while driving at an undisclosed speed, the vehicle started shaking abnormally and stalled. The contact stated that several unknown warning lights were illuminated during the failure. The failure was a recurring failure. The vehicle was towed to the dealer; however, the dealer was unable to duplicate the failure, and the vehicle was not repaired. The manufacturer was made aware of the failure, and an engineer was sent to inspect the vehicle; however, the contact was informed that the vehicle had passed the inspection; however, the failure persisted. The failure mileage was approximately 10,637.”

“Battery drains which locks car unexpectedly. No warning, even with car FOB inside car which creates a safety issue if child or someone is in the car. All doors lock and with no access to FOB cannot open the door with manual key. Also, safety issue if this happens at night or in a parking lot etc. Cannot open doors at all - There is obviously an issue with the battery draining after only a few days. Dealer solution - plug in a battery maintainer - problem if you are parking the car at an airport for multiple days. No place to plug the car in... Lexus needs to figure out what is draining the battery or some fix to stop this from happening - I drive my car several times a week 30 miles at least - still happens. Have had to replace battery twice so far.”

“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…”

“My RX350 experienced malfunction of the Advanced Driver Assistance Systems (ADAS). Messages regarding the malfunction of the ADAS first appeared around mid-August 2024. Upon inspection during the week of August 27 2024, the Lexus dealer, Akron-Canton of Lexus, indicated that the malfunction was caused by rats chewing on the soy-based wiring. The dealership replaced the wiring at a cost of $1,295.10. This is a problem caused by faulty design and inappropriate parts and design. It is inconceivable that car parts would be made of animal food. This put me and my family at serious risk of accident, as my reliance on warnings was severely compromised. Lexus needs to immediately replace the soy-covered wiring with something that is not edible by rodents or any other wildlife. In the interim, an equitable solution would be to reimburse the actual costs as well as compensate for the risks thrust upon drivers by their reckless use of inappropriate material. The repair invoice is attached.”

“Vehicle jerking back and forth aggressively while at a complete stop with foot firmly on brake pedal. Vehicle seems to want to lurch forward.”
