LEXUS Complaints

The Lexus TX 500h is equipped with a 6-speed sequential-shift automatic transmission, which is paired with the Lexus DIRECT4 all-wheel drive system. This setup utilizes a 2.4-liter turbocharged hybrid powertrain to deliver 366 horsepower and 406 lb-ft of torque. During many occasions, the transmission on the 2026 Lexus TX500h would shudder during acceleration or deacceleration. I noticed it happening around 25-40mph mostly and it has happened more than once. I have demonstrated the issue to the dealer on Wed, May 20th around 10:15am Pacific but they didn't know how to address the issue. I did a ride along with the service tech from Lexus of Pleasanton and it happened again during acceleration. The dealer noted that there were no error code when they scanned the system and no observed leaks. I have a video clip but was unable to upload it. The issue with transmission shift thump when this issue happen feels like the transmission locked up. It would shake the vehicle and lose power while accelerating before it starts to gain power back in 1-2 seconds. This causes a safety issue since that pause in acceleration thus this can be dangerous while merging onto a freeway or areas with lots of traffic. I noticed the same issue on some occasions, it would shake during deceleration as well. This issue is intermittent. Maybe Lexus/Toyota can address this with the transmission shifting update. IMO, It's a safety issue that needs to be looked and fixed by Lexus/Toyota. Dealer asked me to come back only. They reset my information screen to address a sliding driving issue where when the power is turned off on the vehicle the seats will go back and immediately go forward.

We were crossing under the light to go to the gas station and we believe the car that hit us ran a red light. It caused right rear damage and side airbags to deploy. There's a metal piece in the tire and its undriveable.

Lexus LX 600 2024 While driving the cars the main monitor screen which displays important information, a splash screen pops up asking for a 6 DIGIT PIN # and obscure the information beneath it. This totally takes you out of the GPS app. Loss of the GPS app while driving in a full freeway in busy traffic is potentially life threatening. Not only that clearing this PIN request the driver finds the GPS App gone. The driver is requited to cancel out of the demand for a “6 digit PIN number only to find this screen obtrusive screen only pop up at infinitum. This puts the driver and other traffic at risk. I have informed the local Lexus dealer but they do not offer a solution for this hazard. No warning lamps Dealer aware

Around 11 am on Sat., May 2, 2026, I was sitting in a very long line in Starbuck's drive thru when my 2025 Lexus RX hybrid suddenly and uncontrollably accelerated--like an uncontrollable bucking horse. Brakes didn't work. I couldn't stop my out of control car, and the multiple computer sensors also didn't stop the car. It was like the throttle was engaged because of a computer glitch. In an effort to avoid hitting the car in front of me, I immediately tried to swerve, but still hit the car, then jumped the exceptionally high curb and ended up in the grass below and almost into the busy road ahead of me. It was terrifying. The car in front of me hit the car in front of her. The exact same issue happened to me on June 18, 2025 when my car unintentionally accelerated--also in a very tight space and going at 2 mph. There was no accident at this time because my car's computer stopped me from plowing into the building immediately in front of me after unintentionally accelerating. The next day at the recommendation of the person who sold me the car, I took my new Lexus to the service department. They gave me a loaner and told me to contact Toyota's/Lexus' Brand Engagement department in order to start the review, which I did. The review was conducted and ended around July 9, 2025 . On Mon., May 4, 2026 I took my car back to the Lexus dealer where I purchased, but was not given a loaner, which I requested, and was told I would need to wait several hours to have this inspected. I then took my car to Boyce Body Werks. A State Farm agent examined my car and initially approved almost $24K worth of damages. Boyce Body Werks is saying when they disassembled my car that there was more damage underneath my car. I also notified Toyota/Lexus about the same issue that happened one year prior. They also refused to give me a loaner, and I am now forced to pay my rental fees. Boyce Body Werks--a Lexus certified dealer has multiple pictures of the damage. My car is still under warranty.

Vehicle suddenly stalled in traffic, check engine light illuminated and lost power.

My less than a year old Lexus GX550 was sitting in the driveway and the sunroof exploded. The car was not moving and it exploded outwards into a ton of pieces. The dealership claims that it is not a warrantable part. No foreign object hit the sunroof, even then it shouldn't shatter, only crack. It is my assumption that defective glass from the factory was installed into my vehicle and caused the sunroof to shatter for no apparent reason.

2025 Lexus TX350, approximately 27,000 miles. Vehicle exhibits rotational clicking/vibration from front drivetrain during acceleration while turning. Dealer is attributing issue to brake pad and rotor wear. Lexus TSB L-SB-0033-24 Rev1 documents a known front drive shaft assembly defect on this platform. TSB applicability check has not been performed. Requesting investigation into whether this defect extends to 2025 model year production.

The car does not alert when a seat belt is not worn in the back seats. This feature is mentioned in the owner's manual, but the car fails to alert when a rear passenger does not buckle their seat belt. I have raised the complaint twice and proved to lexus service center, that car doesn't warn or alert the safety belt. It was also proven and checked by Lexus with their technician. The problem is accuring right from the time car was purchased, When check with the dealer it was designed , but their manual confirms the seat belt not worn warning light is included in the package. It put the any passener riding mainly children at serious risk

The driver’s seat is making cracking, clicking, popping, and creaking noises from the lower seat frame, seat rail, or mounting area where the seat attaches to the vehicle body. The noise is most noticeable during braking, acceleration, turning, driving over uneven roads, and when shifting body weight in the seat. It feels as though the seat has movement or play, as if the seat rails, frame, or mounting bolts may not be fully secure. This is a safety concern because the seat is part of the occupant restraint system and is critical for proper seat belt positioning and airbag protection. If the seat frame, rails, or mounting hardware are loose, damaged, worn, or improperly secured, the seat could shift during a sudden stop or collision. In an accident, movement of the seat could reduce seat belt effectiveness, alter occupant positioning relative to airbags, increase the risk of impact with the steering wheel, dashboard, door, or center console, and increase the likelihood of head, neck, chest, back, pelvic, or leg injuries. Unexpected seat movement could also affect driver control immediately before or during a crash. This should not be treated as a simple interior rattle. The seat mounting bolts, rails, locking mechanisms, adjusters, frame components, and floor mounting points should be fully inspected for looseness, improper torque, wear, cracking, or structural failure. I have also found numerous similar owner complaints online from Lexus GX owners reporting clicking, cracking, rocking, or shifting driver seats that feel loose or unstable. Based on forum discussions and owner reports, there appear to be dozens of similar complaints, suggesting this may not be an isolated issue.

The Pre-Collision System (PCS) activated twice in the last couple of weeks with absolutely no reason. Both times it activated with transmission in reverse and vehicle in process of backing up. But there was no vehicle or person within the vicinity. The sudden braking startled the driver and passengers giving concern about the viability of the vehicle operating in a safe manner for the rest of the trip. The problem has not been seen or inspected by the dealer or service personnel.
