Vehicle is built so that water from hand-washing/rinsing gets under the hood and into a computer causing electrical issues and causing the car to not start. The dealership put a foam/rubber trim around the hood to prevent water from getting in but this won't last forever and, when they tested the other cars of the same model on the lot, they confirmed it happened with those cars also. The manufacturer's statement was that the owner's manual says you are not supposed to hand wash it. This is ridiculous. The owner's manual says you can't pressure wash the engine compartment - which noone did. This was caused during a routine wash at the car wash. It is unlikely anyone would buy a car if they were told they couldn't take it to a car wash. But the concern is that it happened twice and the fix will be temporary. Both times this occurred, the car was parked. The first time, there were electrical issues. The second time, the car refused to start after it was shut off.

There is an ongoing noise issue where I hear a vibration or buzzing sound coming from the headliner or sunroof area while driving at various speeds, especially on uneven pavement. I have reported this concern previously, but the technician was unable to find the cause. On February 25, 2025, a maintenance technician at Jim Hudson Lexus in Columbia, SC, inspected the issue and confirmed an excessive rattle coming from the headliner around the sunroof panel and buttons. The technician noted that part of the internal headliner near the front dome lights is not secured properly, unlike the rest of the padded headliner. Despite this inspection, the noise persists.

The driver's side front wiper blade is not securely attached and lifts off the glass during the drying stage of automatic car washes. Once lifted, it stays in the upright position and must be manually lowered. To prevent this from happening, the wiper blade needs to be taped down. On February 25, 2025, a maintenance technician at Jim Hudson Lexus in Columbia, SC, inspected the wiper and confirmed that the wiper spring is functioning as designed with no defects. The technician explained that the wiper can lift due to the strong wind force from the car wash blower dryer. However, the service advisor mentioned that this issue has been observed at the dealership's on-site car wash and noted that Lexus has not yet released a stronger spring to address the problem. He advised me to report this issue.

On [XXX] my Lexus would not start properly and then I heard noises which were associated with the battery closing down. This included locking all the doors. I was trapped in the car for 50-60 minutes until a repair person unlocked the door. This is a safety issue because the temperature where I live (las Vegas) is over 100 degrees months of the year. According to other Lexus owners, mine was a somewhat common experience. Some people have had the battery fail while driving. A recall to fix the problem is needed. When I contacted both corporate Lexus and my dealer they played dumb and told me to drive the car more often, but no one could specify how much that would be. Purchased in February, 2023 the vehicle has over 25,000 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Airbags failed to deploy during a crash where lexus was hit on driver's side. We got an alert that they malfunctioned. During inspection, the wire for the airbags was pulled which would indicate deployment. Car was totaled.

I drive an NX250 and recently took it to a conveyor-style car wash, where you position your front tire in a groove, shift into Neutral, and let the system move the car through. Upon exiting, I experienced an issue where I couldn’t shift directly from Neutral to Drive. Instead, I had to first shift into Park before I could engage Drive. This was especially concerning because I was worried that the car behind me might not have enough time to stop, potentially leading to a rear-end collision. Difficulty shifting from Neutral to Drive after a car wash is a common complaint, especially with newer vehicles that have electronic shifters or safety mechanisms in place.

My concern is regarding the auto start-stop feature. It is a concern since the feature is tied to both the brakes and engine, and it could lead to other/bigger issues. When stepping on the brakes to come to a stop, sometimes the auto start-stop feature turns on. Upon releasing the brakes, there is a loud grinding noise. I brought it to the dealer twice for this issue. The first time a master technician got in the car with me, he drove it and he was able to reproduce the sound continuously, at least 10 times. I left my car with them for a week and was told they were never able to reproduce the noise again. I brought my car home and drove it for 5 days and then it started making the noise again. I took it back to the dealership and they kept it for another 5 days. I was told again they were not able to reproduce the noise. There have been no warning lamps, messages or other symptoms of the problem. As background, I purchased my car in April of 2023. The noise started in January of 2024, with less than 6800 miles on it. It happened off and on and it took a few weeks for me to realize the noise was tied to the start-stop feature. Once it became more prevalent, that is when I finally called the dealership to explain the issue and got an appointment to take my car in on 2/19/2024. I currently don't have videos to attach but can follow up with videos in the future if needed.

The automatic headlights have a significant delay before turning on when entering a dimly lit parking garage. I have adjusted various car customization settings, but the delay persists. On February 25, 2025, a maintenance technician at Jim Hudson Lexus in Columbia, SC, inspected the issue and confirmed that the headlight sensor is set to the highest sensitivity. The headlights typically take about 15 seconds to activate. Count 15 seconds that is a long time.
