LEXUS Complaints

When accelerating from stop the vehicle has a long hesitation or lag, but allows enough movement in the vehicle to push the vehicle into an intersection. The safety concern is when pulling out across traffic to make a turn the lack of acceleration leave the drive susceptible to being hit by crossing traffic. I contact the Lexus dealership maintenance department and they indicated that it's a know problem and there isn't a recall or a solution. There is no warning light not other mechanical problem. I would not submit this concern if I didn't feel that this is a life threatening concern. There is far to much hesitation in acceleration, compounded but the fact that there is just enough acceleration to put the care in harms way with out enough to avoid a potential accident.

I was just getting off from work starting the engine, the driving meters screen and the head up display were completely off black, I thought that it will turn on after driving but it didn’t. I was driving more than 5 minutes on the free way and both screens were still dark. This is not the first time that this happened. The last time when this was happened, I brought my vehicle to the dealership where I purchased it, but then everything went back normal when I got to the dealership parking lot. They never performed any diagnostic or checking anything. Also the navigation/multi media scene flashing quite a bit. This car electrical system didn’t function properly and correctly when driving and could cause serious accidents or deaths, depending on who was driving. I really don’t know what more failure after this. In the past, Lexus had history of vehicle brake failures and couldn’t stop that claimed someone lives. This issues should be addressed before something else happens. ( I also have video available to support this concern)

On July 19th, with less than 100 miles on the odometer, the vehicle began down and upshifting so hard that it felt like a collision. Additionally, when attempting to accelerate, the transmission would hunt for gears without engaging, resulting in loss of power - creating a very dangerous situation. Lexus is unable to identify a resolution and has had the vehicle in the shop for 2+ weeks

more than 3 documented occurrences of the vehicle sound system go out and does not play music on radio. satellite radio and Bluetooth until the car is shut off at the ignition and restarted.

Vehicle began exhibiting multiple electrical safety issues around April 2025. EMF (electromagnetic field) levels were measured and found to be excessively high, causing physical discomfort and triggering health concerns for my disabled son and me. We both sought medical attention. Two independent mechanics inspected the vehicle and confirmed it showed signs of water intrusion or exposure to hazardous materials — including corrosion, damage to internal components, and abnormal underbody residue. I reported this to Lexus in April and also submitted a lemon claim, but they have failed to act or resolve the matter despite multiple follow-ups. Additional issues include malfunctioning GPS, flickering interior lighting, and system errors suggesting possible electrical instability. I no longer feel safe operating the vehicle due to the ongoing risks and lack of manufacturer response. This is a serious failure of duty to inform, inspect, or repair — and may indicate deeper electrical or structural defects that pose risk to others.

Brakes locked up while driving on the freeway, causing collision with another car and freeway guard rail. CHP report taken. AAA auto insurance does not seem interested in investigating manufacturing defect problems/issues. No dashboard warning/maintenance lights illuminated

2016 NX, F-SPORT. TRANSMISSION FAILURE. DRIVING ON THE INTERSTATE AND SUV JUST WENT INTO LIMP MODE. NO CODE ON DASH BEFORE THIS HAPPENED.

As I was driving southbound on I five in the state of Washington in Stanwood area 8:00 AM my sunroof exploded, causing me to swerve into other lanes and a distraction for other drivers There were no warnings. The sunroof was in a close position, not being used. The vehicle went into repair today being August 1. We did take pictures. Had there been cars directly on either side of me accident would have occurred.

Several time since owning my 2014 LexusIS350 with 141,000 miles on it, it have given inaccurate fuel reading. By almost 100 miles short. Had to disconnect the battery for the ECU to clear so a more accurate reading on fuel can be displayed.

I’m reporting a serious safety issue with my 2014 Lexus CT200h involving the brake booster and ABS pump/accumulator system. This issue is well-documented across Lexus CT200h and Toyota Prius V models, which use the same components. Lexus quietly issued a Customer Support Program (CSP) for the affected part but never notified me. I contacted Lexus and was told they “didn’t have to” notify all owners. After escalating, they claimed a letter was sent, but I confirmed my address and never received anything. Several months before the CSP expired, I noticed inconsistent brake response, a soft/spongy pedal, and warning lights: ABS, traction control, brake, and TPMS. I took the car to an independent mechanic who misdiagnosed it as a TPMS issue. Six months later, a loud chime began sounding repeatedly, unrelated to seatbelt use. I brought the car to Lexus of North Miami, where they diagnosed a failing ABS pump and accumulator — the exact components covered by the CSP. This is a critical safety failure. Loss of braking pressure compromises stopping distance and puts my safety and others at risk. Lexus refused assistance because the CSP expired, even though the problem began earlier and I sought help. Corporate and their Resolution Team were dismissive and unprofessional. The issue is reproducible and confirmed by a certified Lexus dealer. Thousands of drivers online report the same pattern: trouble code C1391, buzzing brake actuator, unexplained chimes, hissing noises after shutdown, and external fluid leaks. Some dealers reportedly told customers to disable the chime rather than investigate. Toyota Prius owners with the same part received repairs under warranty or recall — Lexus drivers did not. I urge NHTSA to investigate this defect before it leads to serious injury or death. This is not normal wear. It’s a known mechanical failure affecting a critical safety system. What makes this even more dangerous is that most owners won’t do the deep digging I did to connect it.
