2023 Lexus GX

Subject: Urgent Safety Concern – Driver Seatbelt Malfunction I am writing to formally report a serious safety concern regarding the driver-side seatbelt in my vehicle. The seatbelt does not retract properly and frequently becomes caught in the door. In addition, the retractor fails to pull the seatbelt back completely, leaving slack in the belt. More concerning, there have been multiple instances where the seatbelt did not properly engage or lock when braking was applied, even though it was securely fastened. I brought the vehicle to the dealership for inspection, but I was advised that this condition is “normal.” I strongly disagree with this assessment. A seatbelt that does not retract correctly or fails to lock during braking poses a significant safety risk and does not meet expected safety standards. This issue raises serious concerns about the reliability of the restraint system in the event of an accident. I am requesting a thorough inspection of the driver-side seatbelt system, including the retractor mechanism, and that any defective components be repaired or replaced immediately. Please document this concern formally and provide written confirmation of your findings and recommended corrective actions. I am very concerned for my safety and expect this issue to be handled with the urgency it deserves.

I bought this 2023 GX460 new in October 2023 from Lexus of Towson in Towson, MD. It currently has approximately 3100 miles on it. Since owning it I have noticed that when coming to a stop and sitting still with the vehicle in gear and the brake pedal engaged normally that the vehicle will start to move on it's own causing more pressure needing to be applied to keep the vehicle still. This initially caught me off guard several times. It is a repeatable problem. I can see that the engine RPM's are increasing by 100-300 by without throttle input which seems to trigger the need to apply more brake. I searched on forums and found other toyota/lexus, including GX owners complaining about this. This is dangerous for obvious reasons.

I do have a lot problem with the GX 460 since I got the vehicle. The vehicle to the right and that the steering wheel was vibrating. We when back to the dealer the next day 4/9/23 and explained the problem to the seller that the car is leaning to the right and on the street and on the expressway between 35-45 mph the steering wheel vibrates horribly. The mechanic says he just did the inspection and everything is right with car. On 4/11/23 we went back to shop with the same problem. The mechanic says the checked the execissive road force and rotated and imbalance of tires. On 4/15/23 I went back to dealer to returned the car, because they have not solved the issue with the car. They told me they did something to vehicle but, they refused to explained why the did. On 4/24/23 I spoke to the manager from the shop and I told him if they are able to fix the car. I do not longer wanted the car. They setup an appointment with the master technician to double check what was wrong with car. The master tech told me the only thing can do is to move the steering wheel again. The car is leaning to right and steering wheels is vibrating. On 4/30/23 I spoke to Manager from the dealer and he told me that he couldn't do anything else for me. They won't be able to resolved the problem with the leaning and steering wheel. If I have any other complaints I need to call Lexus. When the vehicle is leaning to the right and pulling to the side is not consider a premium experience. The car is very problematic. Other possible cause of vibration and shaking include: bent wheel, improper alignment, worn suspension components, driveshaft problems, tire are out round and a lot money. Money that I don't have. This problem is not new for LEXUS or the dealer. There are many complaints in NHTSA and TSB in reference to LEAN to the right and Steering wheel. This is one reported L-SB-0015-21 and LEXUS haven't take any action to resolve this matter. Unfortunately, the customer is the only one who loses.

THIS VEHICLES PARKING BRAKE FAILS TO HOLD THE WEIGHT OF THE VEHICLE, UNLESS THE TRANSMISSION IS ENGAGED IN "P" (PARK). As a result, the weight of the vehicle rests on the transmission notch that is engaged with the Park position of the transmission. If the vehicle is stopped and the parking brake is engaged, the vehicle will roll in the direction of the downhill. The parking or emergency brake does NOT hold the weight of the vehicle without the transmission!
