2023 LEXUS RX Complaints

The contact owns a 2023 Lexus RX350. The contact stated that while driving at an undisclosed speed, a system malfunction error message populated on the instrument panel. The vehicle was taken to a dealer, where the system was reset. The dealer advised the contact that the error message could populate again and that a software fix was being worked on. The contact stated that the failure reoccurred. The manufacturer was made aware of the failure. The failure mileage was approximately 9,000.

When driving Lexus 2023 RXH with all safety except lane assist features, it suddenly veers to the right under specific conditions below - Have enabled ProActive Driving Assist - The car is travelling on a straight road, and has line markings (yellow left side, white right side) - There is a right turn to the side of the road, and the white shoulder markings taper off and merge to the side of the road (where there is a right turn) The car suddenly veers right and follows the white shoulder marking ignoring the yellow central line and the straight road. Seems very dangerous. Note that Lane Keeping Assistance is disabled (but I checked it since it needs something checked), Adaptive Cruise Contro is not engaged (inner road), but other options are all enabled, including Lexus feature called ProActiveDriving Assist. This is happening especially after the June 2024 firmware upgrade (or after Dealer service)

This 2023 Lexus RX350H and several others vehicles of the same model and year and the 2024 year model have made sporadic roof popping noises that appear to be causes from heat expansion and/or flexion of the vehicle. I have taken this vehicle in a total of seven (7) times to two different Lexus dealerships. The first (4) trips to the dealerships they were unable to duplicate the vehicle, because they didn't keep it long enough. The last three (3) trips to Sewell Lexus in Fort Worth they heard the roof noises and were unable to fix the problem. On the last visit the Lexus Representative supervised the repair and determined that the problem was what the called roofs bows or what appears to be roof supports had come detached from the inside of the roof. The dealership supposedly re-glued the bows/supports and claimed the vehicle was repaired. Three days later the car made the popping noise and has done it often own since then. I have personally driven a similar model loan vehicle from the dealership and it made the popping roof noise also. I have read recent threads this year on the ClubLexus forum site where other Lexus owners of this model vehicle (Both 2023 and 2024) have stated that their vehicle has also made the roof popping noise. I believe this is a Lexus manufacturing defect that they have not been able to fix and have ignored my suggestion that this is a Lexus model defect and also my request for a replacement vehicle, since they haven't been able to fix it. They took the car apart inside to the bare metal the last time they worked on it. This noise has happened when driving, turning corners and when parked and not running.

We have encountered 2 instances of Unintended Acceleration. Lexus has inspected the vehicle and states they could not find anything wrong. In both instances the car jumped forward without notice. No warnings were given. The first time it occurred there was over $8,500 worth of damage. No damage the second time which occurred on May 20, 2024.

The contact owns a 2023 Lexus RX350. The contact stated that on three occasions while driving at various speeds, the vehicle lost motive power for approximately 20 seconds, and then accelerated as needed. There were no warning lights illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 4,200.

First Lexus I have ever owned and prob last. I am very disappointed in the paint quality of there cars. I have sustained so many rock chips and scratches from normal driving , no tailgating, or following to closely. Surprised how bad the paint is able to hold. The chips go straight through the paint to the black plastic underneath. My bumper looks like Swiss cheese. I was told by the dealer the design of the car requires it to be PPF. I would have done it if they told me before I drove it 13k.

LEXUS claims the car run 27miles per gallon. But the actual miles I got only 22.1 miles after owning it for a year . THIS IS A BIG LIE. Please take appropriate action!

The rain sensing wiper do not work properly. The wiper swipe once then stop. I have to turn them off and on again to get them to restarted. Also once they do start, they randomly stop for no reason. I have had it to the dealer twice. I was told the dealer contacted Lexus who confirmed this is a problem, with NO fix. The dealer also tested all the new RX 350's models, 2023 and 2024 on their lot, and ALL of them had the same problem. This is a major safety hazard that will cause accidents. It was serviced at Thompson Lexus in Doylestown, PA.

We were driving down the expressway when our panoramic window exploded. There was no one around us, therefore it was not a rock that hit us. Thankfully, we had had the window tinted, therefore the glass didn't shatter around us. We took the car into the service department, and the service man said that it was a rock, but it was not a rock.

I bought vehicle on May 31, 2023. In October 2023, while I was driving, a warning came on saying system malfunction, to visit dealer. I left my car with Lexus Dealer on Friday, I didn't get my car back until the following Tuesday. Then it happened again on 11/28/23 again the warning light came back on indicating system malfunction, visit dealer, and received the car back on 12/4/23. My vehicle is only 4174 miles.
