2017 Lexus RX Complaint Log

The contact owns a 2017 Lexus RX450H. The contact stated that while driving at an undisclosed speed and depressing the brake pedal, there was an abnormal sound coming from the vehicle. The vehicle was taken to the dealer to be diagnosed. The vehicle was diagnosed with brake actuator assembly, bleeder plug cap, brake actuator cover, and brake fluid reservoir assembly failures. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 59,380.

Summary of Issues: 1.On March 3, 2026, I contacted my service manager regarding my inability to open the driver’s side door. I also reported persistent rattling sounds coming from the interior panels and driver’s side door, extending toward the rear of the vehicle that leads to the gas cap door. I was forced to enter through the front passenger door. 2.On March 4, 2026, I dropped my vehicle off at Lexus service department. My service manager got into my vehicle and was unable to exit through the driver’s door. This presents a serious safety hazard. I expressed concern that the issue could be electrical in nature; however, I was advised that new door locks were needed. 3.On March 10, 2026, my vehicle was returned to me after being serviced, with the explanation that both front door locks had been replaced. I questioned why the passenger-side lock was replaced, as I had no prior issue with that door. 4.After picking up my vehicle, I traveled and left it parked at Austin Airport until 3/15/2026. Upon my return, I experienced the exact same issue-the driver’s door would not open. 5.On March 16th, 2026, I returned the vehicle to Lexus service department for further evaluation. This repeated inconvenience has been time-consuming and frustrating. As this is a luxury vehicle. 6.On March 18, 2026, I was notified that my vehicle was ready for pickup and was told the issue was related to the door bezel. Upon retrieving my vehicle, I immediately noticed that the driver’s door lock was visibly missing. I returned to the service department and documented the issue with photographs. I was then informed that the driver’s door panel would need to be replaced. Later that same evening, while attempting to refuel my vehicle, I encountered difficulty opening the fuel door. I again heard the same rattling and popping sound extending toward the gas tank. At this point, I am concerned for my safety and do not feel comfortable operating this vehicle.

Please see attached regarding LEXUS RX450h brake actuator failure concern. Thank you for your support.

My vehicle has 39800 miles (64k kms). I have the exact same issue with my driver side heated seat. The lowest setting may take time to warm up then gets scorching hot. Eventually after heating it up, I will turn it off manually to stop heating it, as it burns. My wife also mentions that the passenger side as well doesn’t seem to heat much. At this low of kms, I should not have this issue but saw someone else have the exact same issue. I have not taken it to the dealer yet as I fear they will charge a fee just to verify the problem. I have an old ES300 and I do not have this problem with the heard seat. My trim level is also the ultra luxury.

3 months before the accident the power steering light came on twice and went off. The day of the accident the brake light came on when I started the car that day. It disappeared when I was put in drive. I was entering onto the highway to merge with the traffic. Another car waiting for the light to turn green so he could enter also. My car didn’t stop because my brakes failed and the collision avoidance system didn’t work either. No sounds nor warnings. I have photos of the message that was displayed on the dashboard. Tried sending photos but it didn’t work.

My vehicle, a 2017 Lexus RX 350 with approximately 111,872 miles, experienced a near-total failure of the infotainment/navigation screen approximately five months ago (around June 2025). The system would only display the introductory safety message, backup camera feed, a single radio station, and basic map locator functionality—rendering the navigation, full audio controls, climate integration, and touch interface inoperable. This issue severely impacted the vehicle's usability and safety features, forcing me to seek immediate professional service.

The contact owned a 2017 Lexus RX 350. The contact stated while making a left turn exiting a car wash, the vehicle unintendedly accelerated independently and crashed into the commercial building where it came to a stop. The brake pedal was depressed but the vehicle was in full throttle and failed to stop. The air bags did not deploy. No warnings light illuminated. No Medical Attention was needed. During the failure, the contact was the only occupant seated in the vehicle. The contact sustained injuries to the head, black and blue marks on the left side of her leg and shoulder as well as her left knee sustained swelling the right of her bottom was also bruised. A police report was filed. The vehicle was towed to impound lot by the insurance company and then towed to a salvage lot. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 53,000.

NHTSA Safety Complaint – Seat Heater Defect Vehicle: 2017 Lexus RX 350 Mileage at purchase: 45,430 Purchase date: Feb. 17, 2025 Dealer: Lexus of Tacoma at Fife, WA Description of Problem: The driver’s seat heater does not function properly. It is slow to activate (5–6 minutes), then overheats uncontrollably even when set to “LOW.” On multiple occasions, the seat became hot enough to cause burns through clothing. Defect Confirmed by Dealership Service Staff: Dealership staff confirmed that the driver and passenger seats heat at different rates. This matches a known defect identified in Lexus Technical Service Information Bulletin L-SB-0038-18 (Oct 10, 2018). Additionally, they confirmed that the drivers' seat spikes to uncontrolled high temperatures, even on the "LOW" setting. Despite this, the dealership refused to repair the issue without an extended warranty and suggested using a sheepskin seat cover to prevent further burns, which is prohibited in the vehicle manual. Safety Hazard: •The defect caused burns to the driver. •The driver's elderly mother, who has peripheral neuropathy in her legs, did not feel when the passenger heater was accidentally turned on, highlighting the risk of undetected burns should the heater defect remain unrepaired. •Risk of fire is also present given the uncontrolled heat and inherent electrical issue. Attempts to Resolve: Reported to dealership on 3/28/25. Dealer disclaimed responsibility. Reported again to dealership on 6/25/25. No response. Reported to Lexus Corporate Customer Service on 8/28/25. Summary: The seat heater malfunction is a confirmed manufacturing defect, already documented by Lexus in a TSIB. Not mentioned in the TSIB is the additional problem of uncontrolled heat spikes, which poses significant risk of burns or fire. Request NHTSA investigation and corrective action.

1. Engine timing cover leaking 2. Oil could leak out emptying which could cause the engine to stop working at any given time 3. Problem has been confirmed by Hennessy Lexus dealership in Duluth, GA but they will not fix it. 4. Vehicle has been inspected by the dealership 5. No signs, I found out from the dealership after taking it in for an oil change

Sunroof exploded while driving down the road!! Called lexus they said it must be due to a rock breaking it.

I bought this car in March 2020. We took it to the Kingsport, TN Lexus dealer Sept. 14, 2020 for several warranty issues and a recall factory interior front door handle replacement. Today, 9/3/24 the front driver’s side interior door handle broke and the door cannot be opened from inside the car. Called local dealer who said that it was guaranteed for 12 months or 12,000 miles. I find this completely unacceptable. I am [XXX] and have driven cars for over 40 years and I have never had a car handle break. For this handle to basically last four years is unacceptable and unsafe for any Lexus driver. At this point I question as to whether the repair was actually made. If in fact replaced, I am shocked by the lack of quality in a repair that was to have fixed a serious issue. Driving a car when you cannot open the door is not something I recommend to anyone! I have called Lexus National customer service and they have opened a case. I do plan to have this repaired and I do not plan to pay for what I consider to be very low quality part replacement.

When checking the emergency SOS function in my car I found that it did not work. I called Lexus support and was told that the following safety systems would no longer be operative: Lexus Enform Safety Connect including Automatic Collision Notification; Enhanced Roadside Assistance; Emergency Assistance Button and Stolen Vehicle Locator; Lexus Enform Remote including Remote Engine Start/Stop, Door Lock/Unlock, Vehicle Finder, Guest Driver Monitor, Vehicle Status and Alerts, Key Fob Remote Start, and Integration with Alexa and The Google Assistant; Lexus Enform Destination Assist including 24-hour live response center agent; Lexus Enform Service Connect including Vehicle Health Report, Vehicle Alerts, and Maintenance Alerts; These include safety systems that I rely on, especially when driving on interstate highways, and were included when I purchased my car. I had no warning that the services would cease to function in October of this year. Lexus states that these systems will no longer function because telecommunications providers will no longer support 3G service. This is certainly a safety issue for me and for other drivers and I believe that Lexus should be required to modify the hardware/software in these vehicles to function in a 4G/5G environment. Lexus representatives state that Lexus has no plans to correct these safety issues. I am requesting that NHTSA review this matter as a highway safety issue.

235/65r18 tire. I was driving on the highway and all of a sudden it was a loud noise and immediate tire noise. I struggled to slow the vehicle down and pull to the side of the road The tire is absolutely destroyed both on the inside and the outside side walls of the tire. I could have had a horrible accident because the car was completely out of control when the tire blew

The sunroof glass spontaneously exploded into thousands of pieces while driving on the interstate. There was no impact what so ever to the glass and the outside temperature was 95 degrees. The shattered glass fell into the vehicle and left a huge hole in the center of the glass panel. My safety was at risk due to explosion of glass while driving at an elevated rate of speed of 75mph. All while traveling over 100 miles from home and then having to drive the vehicle home with a gapping hole in the roof. The surrounding drivers were also at risk due to the glass flying off and hitting their vehicles. There were no cracks or failures to the glass prior to the glass exploding. There were no warning lights, messages or symptoms.

My car has an oil leak from the timing chain cover gasket that was discovered by an independent mechanic at 37,465 miles. The dealer confirmed the leak on June 14, 2024 during a recall replacement of the fuel pump. The repair is very expensive and the car is no longer under warranty. This is the second occurrence of this same issue. The first occurred in April 2021 at 24,192 miles and was repaired by the dealer under warranty. There were no warning lamps or messages of the problem but there was oil on the ground where I park. The car is available for inspection. An internet search confirms that this is a known and common problem with the Lexus RX350 (and specifically the 2017 model) for many owners with some occurring more than once as in my case.

During a routine maintenance at the Lexus dealer where vehicle was purchased, we were told that there was a potential oil leak from ("potentially") the engine where the block, cylinder head, and timing cover components meet. The quote we got for the repair is $18,781.52 as a good portion of the car needs to be disassembled to access the motor. This issue was only brought up after the warranty expired. The Toyota 2GR-FKS 3.5L V-6 engine in this vehicle is known to leak in this area due to the gasket mating surfaces in the area mentioned above not sealing completely requiring silicone RTV caulk to be installed during engine assembly. If this is not done correctly leaks occur. Lexus refuses to make good on this saying the car is out of warranty. Ironically, after receiving the quote from the dealer for the repair, we received an offer to extend the warranty - available only after this $18k repair was completed.

The contact owns a 2017 Lexus RX350. The contact stated that prior to starting the vehicle, there was an abnormal fuel odor on the exterior of the vehicle. The contact stated that when the vehicle was started, the odor was inside the vehicle. The contact stated while driving 40 MPH, the accelerator pedal was depressed; however, the vehicle failed to respond as needed. The contact stated that while taking the vehicle to the dealer and driving the vehicle into the dealer parking lot, the service representative noticed a trail of fuel coming from the vehicle. The contact and her three kids exited the vehicle. The vehicle was diagnosed with a failed fuel pressure sensor connection and leaking fuel line. The contact was informed that the fuel pump and fuel line needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 73,403.

The lane departure camera is mounted to the windshield and the glass between the windshield and the camera becomes fogged over time. This results in the lane departure system becoming less sensitive or inoperable - in particular in low-light or when sun was shining toward the camera (dusk/dawn). It also results in the adaptive cruise control becoming more erratic (abrupt in stops). This design puts the user of the vehicle and others around them at risk as key safety systems are compromised. This is in an area that is generally not easily accessible for an owner to clean. However, I was able to remove the camera and clean the glass (please see pictures) and normal function resumed immediately. This is not an operation a owner should attempt and there are warnings about camera re-calibration. I believe NHTSA should consider this a design defect that could be cured by a visit to a dealer (periodically) with their technicians performing a complementary cleaning of the interior camera glass to ensure the camera continues to function properly. About the car: This car has never been in an accident, non-smoker, always garaged (no sun/heat exposure) driven in the city with no dust or debris in the cabin (exceptionally clean inside and out) 33,500 miles at time of cleaning (photos attached). I believe this fog is due to off-gassing of cabin materials that occurs naturally as the vehicle ages.

The contact owns a 2017 Lexus RX350. The contact stated that upon attempting to exit the vehicle through the driver's side, the door failed to open. The contact was able to exit the vehicle after reaching through the open window to open the door using the exterior door handle. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 24,000.

I WAS SITTING AT A COMPLETE STOP FOR MORE THAN 45 MINUTES BEHIND A FATALITY ACCIDENT ON THE HIGHWAY THEY HAD CLOSED WHILE OCCASIONALLY REMOVING FOOT FROM BRAKE TO INCH FORWARD A FEW FEET A BEST AND THEN STOP AGAIN NEVER TOUCHING THE ACCELERATOR WHEN I REALIZED AT ONE POINT TRAFFIC BESIDE ME WAS MOVING, I THOUGHT, IT WAS MY RX 350 WHILE PRESSING BRAKE ALL THE WAY TO THE FLOOR WITH NO RESISTANCE I ATTEMPTED TO PUT THE CAR IN NEUTRAL TO SEE IF IT WAS SLOW ME DOWN AS AN UPCOMING CRASH WAS UNAVOIDABLE. NO BRAKE ASSIST, PRECOLLISON WARNING OR ASSIST, NO EMERGENCY BRAKING, NO RESISTANCE FROM BRAKE PEDAL AND ***NO WARNING LIGHTS CAME ON AT ALL PRIOR TO IMPACT WITH THE BACK OF A STOPPED SEMI TRUCK** and during the entire incident the speedometer remained at zero or moved a tiny bit off of zero as if it was pulsing somehow and the accelerator was never touched while car felt like I was being pushed from behind, randomly accelerating on its own before impact.

•What component or system failed or malfunctioned, and is it available for inspection upon request? Amplifier is in failure. There is no sound. This is a very common problem with Lexus. It is available for inspection upon request. •How was your safety or the safety of others put at risk? (1)Navigation and Directions – Navigation is working properly, but no sound coming out from navigation. This could lead to confusion and distractions. I have been using my phone to navigate, and this is not safe using my phone while I am driving. (2)Distracted driving – There is no sound using Bluetooth, so I disconnect my phone with the car’s Bluetooth. When I receive a phone call, I have to check the phone to see if this is an urgent call, like calling from my son’s aftercare. If the call is urgent, I have to respond to the call. This doesn’t allow the driver to make hands-free calls. This can lead to distractions that compromise the driver’s attention and increase the risk of accidents. •Has the problem been reproduced or confirmed by a dealer or independent service center? This issue was checked by Lexus Englewood Service center, and they confirmed that this is the amplifier failure. I purchase this vehicle at Englewood Lexus. •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This issue was checked by Lexus Englewood Service center, and they confirmed that this is the amplifier failure. •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps, messages or other symptoms of the problem prior to the failure. Sound system failure has appeared since April 2023.

The contact owns a 2017 Lexus RX350. The contact stated that upon a cold start, an abnormal knocking sound was coming from the right side of the engine without warning. The contact stated that the knocking noise became louder upon shifting gear but would cease once the engine was warmed up. The contact also noted that the brake pedal was firm while depressing the brake pedal. There was an unknown brake warning message displayed. Upon investigation, the contact discovered NHTSA Campaign Number: 18V211000 (Service Brakes, Hydraulics) which he linked to the failure. The dealer was notified of the failure and informed him that the vehicle was not under recall. The dealer provided an estimate for the repair. The manufacturer was notified of the failure and provided a case number. The vehicle was not repaired. The failure mileage was approximately 25,800.

At approximately 6:45pm on Tuesday, December 27, I was driving in Nassau County, NY, when my sunroof exploded. The sound was terrifying and I was very concerned that I was shot at or hit by an unknown object. At first I thought the object hit my car or my back windshield. I looked and did not see any holes anywhere but I could hear air coming into my car. I moved my sunroof shield and saw a gaping hole and shattered glass.

Brakes make a squeaking sound when brakes applied. They are loud, this sound is not coming from brake pads or rotors. They are alarming and cause anyone to become startled and could cause crashes.

DAMPER SERVO SUB-ASSEMBLY, AIR CONDITIONER RADIATOR, NO. 2 Part Number: 8710608120 Which also called the bend door actuator failed on my 2017 RX450h at 80,000 mile.The part or door opens to mix hot air form the heating core and cold air to supply heat to the interior of the vehicle. When the bend door actuator part failed you have no heat and to replace it you have to he the dash removed (poor engineer design) and face bills for service over 6,000 dollars. This part failed appears to be prevalent with this manufacturer. Other manufacturers such as Mercedes benz, Porsche, and Honda etc. do not appear to suffer from this part failure problem at the same mileage. This appears to be a lemon part form this Manufacturer.

I purchased a 2017 Lexus Rx 450h Fsport last year at Carmax. About 6 months ago, I noticed that every time I pressed the brakes, there was a chirping sound. I figured it could be dust in the calipers. As the months went by, the chirping sound has gotten louder and now it affected the parking brakes. I researched this problem and many people online have also complained that they are hearing this Chirping sound or what the Dealer calls a "Brake Squawking" sound. I received a letter from Lexus saying to bring my vehicle in for a possible Brake Booster and Fuel pump failure. So I brought my car to the dealership. Since it's there I complained about the chirping sounds that it's making every time I step on the brakes and when the parking brake is applied. I told the Advisor at Lexus that a lot of people online have also complained about this problem and it should be a "Recall". He said that it's not a Recall. To make the story short, the Dealership didn't find anything wrong with the Brake Booster and the Fuel pump. What's causing the Chirping or Squawking sounds was the "Brake Actuator". I was quoted $4,327 to have these parts replaced because my Rx was already past the 50,000 miles warranty. I brought my Rx to the Dealership at 55,483 miles. It was a great thing that we purchased the extended warranty at Carmax called the Max Care which I only had to pay a $100 co-pay. Amazing! It took about 2 days to have this completed. Now, the chirping sound has disappeared when I press the brakes and when the parking brake is applied. I truly believe that this should be a Recall by Lexus and be covered. It shouldn't matter how many miles the customer has. This is a safety issue. The brake actuator shouldn't fail this soon. I have a 2007 Lexus GS350 with 225,000 plus miles and I never replaced the Brake Actuator. I don't know if even has one. The bottom line is when I press the brakes on that car, there were never any chirping sounds.

The on board mapping system is no longer accurate for speed limits and as such ( assuming speed limits were lowered for safety reasons) creates an unsafe driving experience. Other manufacturers update there mapping technology at no cost ( eg Audi) Lexus require $500. It needs to be free.

I just picked My Car up from Bakersfield Motor Ciry Lexus . My engine was replaced with a engine at this location with 65k . I have now notice my car jerk during acceleration from a stop position or uphill possibly from the transmission . I respectfully requesting a claim be opened on this issue as I didn't have the issue until engine replacement. I am also requesting a courtesy evaluation and stress test on the transmission at my home dealership Newport Beach Lexus. Ever since engine replacement the car has been bucking during acceleration 0 to 45.

It was found during inspection of front break calipers that rubber dust boots on 3 out of 4 pistons (2 pistons per caliper) were torn apart. Chunks of cut out rubber boots were found inside the pistons. The car never had break work done since the time it was manufactured. The brake pads on both front wheels are still factory original. The only way for dust boots to get damaged is to have improper installation during car assembly process where rubber boot is not tacked fully inside caliper. The issue would result in premature wear of piston seals dust boot supposed to protect. Wearing off seals would result in leak of break fluid and potential sudden loss of break functionality. The workmanship issue is likely to be impacting other vehicles assembled on the same factory floor by the same employee.

On [XXX], my wife, [XXX] , was driving our Lexus RX 350 when she noticed engine smoke without any prior notifications from the vehicle. Concerned for her safety, she pulled over and contacted Geico for assistance. Geico arranged for the vehicle to be towed to Motor City Lexus, a trusted Lexus dealership in Bakersfield. Once we the dealership performed a diagnosis they advised that the issue involved coolant being leaked into the engine that caused the smoke with in result caused the engine blow head gasket. After doing some research I saw an article from consumer reports about some Lexus and Toyota SUVs doing the exact same thing which made me decide to wrote about this incident. I am including the link regarding the report [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Sunroof Glass Failure Report: I was traveling on the interstate at the speed limit and there was a loud bang, which after I pulled over, discovered that the sunroof had "exploded". There was no sign of anything hitting it and the weather was typical for the Texas Gulf Coast in a July morning. Luckily, the underneath cover for the sunroof was closed, because several pounds of glass fragments were released in the sunroof failure and would have been all over the passenger compartment of the Lexus. This is a major safety issue, especially if a child is fastened in a car seat with this problem directly overhead. This issue has been reported by numerous other Lexus owners and seems to occur often enough that it should be a concern for the manufacturer, but I am not aware that they have taken any action on this. A photo of the failed sunroof is included.

Rear ended vehicle automatic braking did not activate

I hear a loud clicking sound that is coming from the vacuum pump that sends vacuum to the brake booster, I am concerned that it could eventually cause braking issues.in the future if not corrected ,i have read multiple forums and it seems to be a common problem with this particular vehicle and ones similar to it, I would like to have this issue resolved before a traggedy occurs.

I was driving up a hill, turning on to a dirt road. I had my foot on the brake as I was going down hill, I bounce from the crevice on the dirt road. My car started going faster, I kept my foot on the brake trying to stop, but it did not STOP. I avoided hitting a parked car and slammed in to a K-rail. My car would not STOP.

The contact owned a 2017 Lexus RX350. The contact stated while driving 45-50 MPH on the highway, another vehicle that lost control and crashed into the contact's front and side of the vehicle. The driver's front air bag did not deploy. The contact suffered minor injuries to the face from the glass front windshield, a cut and burn from the seatbelt, and a bruise to the arm. Medical attention was received. A police report was filed. The vehicle was towed to a tow yard. The vehicle was deemed and destroyed by the insurance company. The manufacturer was contacted and notified of the failure. The approximate failure mileage was 30,000 The contact stated that of all the airbags, none of them deployed at the time of the accident. As a result, the vehicle was totaled.

At the beginning of the Month of May as the weather got hot I turned on the AC and suddenly the windshield cracked more than 6 inches long with no previous damage.

Today, May 5th approximately 9am travelling on 287 East (Westchester County, NY) I was startled by what sounded like an explosion - I literally ducked in the driver's seat. Sounded like it came from overhead and then I observed that no other car seemed to have slowed or was affected. I put on my hazard lights and drove a 1/2 mile or so until I could safely pull over. As I'm driving I can hear over my head rumbling and the wind as if the sunroof was open - but I hadn't opened it. When I was able to get out and take a look the closed sunroof had shattered outward - it reminded me of a volcano pattern. Left my hazards on, got unto local roads and drove car to dealer - Ray Catena Lexus of White Plains, where we purchased the automobile. Service told me something must have hit me at the right angle. They could find no debris besides broken glass in the sunroof compartment. I was shaken and went through the process of figuring out a loaner and cost to repair. Upon my return home I spoke to my husband and we realized it just didn't make sense. We started doing research and discovered that the Toyota corporation may well be aware of these incidents, they've been happening to different models of Lexus cars/SUVs for years - different models all over the country. In California there is currently a class action suit against the corporation. I'm thankful I was driving and not my daughter and that I had the presence of mind not to lose control of the car or open the soft inside cover of the sunroof. This needs to be investigated, Toyota makes many different model cars, trucks, SUVs and this is unacceptable. My one regret is that I didn't have the presence of mind to take a photo.

The contact owns a 2017 Lexus RX350. The contact stated that while driving approximately 60 MPH, the glass sunroof suddenly exploded causing shards of glass to fall into the cabin of the vehicle onto the driver. The contact indicated that no object had struck the sunroof to cause the glass to shatter. No injuries were reported. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The manufacturer was not yet contacted. The failure mileage was 58,190.

I was involved in a side collision accident and my car was determined to be total loss by the At-Fault's insurance company. I was lucky that my son and I came out with bruises and a few scratches but the main problem here is the airbags. It DID NOT deploy at all when it was hit. The force hit us from lane 1 all the way to lane 3 and damages to the structure near cabin was found by one of the vertified accident body shop. So yes, no airbags were deployed.

The car stalls while I'm driving, and it almost caused a traffic. Accident, I have been trying to contact my local lexus dealer and they keep hanging up the phone when I try to call and make appointments

Engine hesitation. sometimes the engine suddenly slows down or like lossing it’s power while running on the freeway or making a turn or going uphill . This is a very scarry situation everytime it does .

The contact owns a 2017 Lexus RX350. The contact stated while driving at various speeds, the sunroof was rattling. The contact had taken the vehicle to the dealer where after a test drive, the contact was informed that the failure was with the brakes, not the sunroof. Overtime, the failure worsened, and the vehicle was taken back to the dealer where the contact was provided an estimate for the replacement of the sunroof. The manufacturer was notified of the failure. The vehicle had yet to be repaired. The failure mileage was 35,461.

The contact owns a 2017 Lexus RX350. The contact stated that while driving at various speeds, the vehicle hesitated upon depression of the accelerator pedal, without warning. The contact had taken the vehicle to the dealer and was informed that the vacuum pump was defective and needed to be replaced. Upon investigation, the contact discovered NHTSA Campaign Number: 18V211000 (Service Brakes, Hydraulics) which she linked to the failure. The manufacturer was also notified of the failure and the contact was given a case manager. The vehicle was not repaired. The failure mileage was approximately 24,000. The contact stated that the vacuum pump was replaced at their expense and is requesting a reimbursement. The vehicle always had issues with the vacuum pump ever since the contact purchased it in 2021. The contact claims that they were told that the vacuum pump issue was normal. The 65k warranty of the vehicle had expired before the problem was dealt with.

The contact owns a 2017 Lexus RX-350. The contact stated that while driving at an undisclosed speed, a strong chemical odor was detected coming from the cabin filter. The contact experienced severe headaches and a numbing, sour tongue sensation after the failure. The contact had replaced over 12 cabin filters and had the vehicle detailed where the interior cabin was shampooed and cleaned however, the failure recurred. The dealer was made aware of the failure but informed the contact that the vehicle was tampered with and to go through his insurance company for the repair costs. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 19,000.

I WHEN TO A CAR WASH FACILITY AND THE ICS SENSOR WHEN CRAZY!!! (FLASHING THE WARNING LIGHT). NOW MY CAR GIVING ME A ICS MALFUNCTION. THE AUTOMATIC BRAKING DON'T WORK AND THE PARKING ASSISTANCE NEITHER. I BELIEVE THIS IS A MANUFACTURING PROBLEM DUE SAME CAR MODEL AND YEAR EXPERIENCE THE SAME BUT IT HAS DIFFERENT VIN SO THERE IS NOT A RECALL FOR MY VIN.

My vehicle is experiencing a mechanical failure of the brake actuator/booster assembly, manifested by a "squawk/bark" noise and abnormal pedal feel during braking. This is a known defect recognized by Lexus under Customer Support Program 23LE04. The dealership technician confirmed the noise is present and recommended a full replacement of the ABS actuator. However, Lexus is denying coverage because the onboard computer has not yet triggered a Diagnostic Trouble Code (DTC). By denying the repair, Lexus is requiring me to operate a vehicle with a confirmed mechanical brake malfunction, which increases the risk of a crash, increased stopping distance, or total brake power assist failure. March 2021 (60k miles): Actuator was replaced under warranty for this exact failure. December 2021 (74k miles): The failure recurred. Lexus and the dealer refused to cover the diagnosis/bleed, forcing me to drive a defective vehicle. February 2026 (110k miles): A Lexus dealer confirmed the part is failing again and quoted $3,000 for replacement. Despite a manufacturer program (CSP 23LE04) existing for this exact part, Lexus refuses to honor it without an electronic code, even though the mechanical failure has been physically confirmed by their own technicians. The component is available for inspection.

DRIVING ON HIGHWAY, MY VEHICLE STALLED WHEN I HIT GAS PEDAL, THEN IT RESUMED NORMAL SPEED. THIS HAS HAPPEN MANY TIMES, BUT SEEMS TO BE MORE NOTICEABLE NOW. I DON'T FEEL SAFE DRIVING THIS VEHICLE

THE AIRBAGS DID NOT DEPLOY. THERE WAS NO RECALL EITHER. I DON'T KNOW IF THERE IS AN ISSUE OR NOT BUT I WOULD HATE TO SEE SOMEONE GET HURT BECAUSE AIRBAGS DID NOT DEPLOY SEE PHOTO OF DAMAGE. HAVE PICTURES BUT SIZE PROBLEM DIDN'T KNOW HOW TO REDUCE SIZE

WHEN FLOORING THE ACCELERATOR IT HESITATES AND BUCKS
