  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.

  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.

  I LEASED THE VEHICLE AT THE END OF DECEMBER 2016. SOMETIME IN SEPTEMBER, MY WIFE STARTED TO NOTICE AN ODD SMELL IN THE CABIN. ON SAT 10/7, MY WIFE NOTICED THE FRONT CARPET WAS COMPLETELY SATURATED. I GAVE IT A FEW DAYS TO DRY OUT BUT WHEN IT DIDN'T GET BETTER I BROUGHT IT IN FOR SERVICE I EXPLAINED THE ISSUE TO THE SERVICE MANAGER AND WITHOUT EVEN LOOKING AT THE VEHICLE HE SAID HE HAD A FEELING HE KNOW WHAT IT WAS. HE EXPLAINED THAT SPIDERS GET INTO THE AC DRAIN PLUG AND CLOG IT CAUSING WATER TO BACKUP INTO THE CABIN. THE PADDING AND CARPETING WOULD NEED TO BE REPLACED AND MOLD REMEDIATION WOULD BE NEEDED (THE MOLD IS WHAT WAS CAUSING THE ODOR). HE SHARED THEY JUST DID THREE OF THESE REPAIRS IN THE PAST SEVERAL WEEKS AND TOLD ME THE REPAIR WOULD COST AROUND $5,400. HE CONTINUED TO EXPLAIN THAT THIS WAS NOT COVERED UNDER THE WARRANTY AND THAT I WOULD HAVE TO PUT A CLAIM THROUGH ON MY INSURANCE. AFTER TWO DAYS HE CAME BACK AND CONFIRMED A "SPIDER INFESTATION." I QUESTIONED HIM SINCE I FOUND THIS WHOLE SCENARIO ODD. HE TOLD ME HE DIDN'T HAVE AN EXACT NUMBER BUT THAT THE DEALERSHIP HAD PREVIOUSLY PERFORMED BETWEEN 15 AND 20 OF THESE REPAIRS AND THAT TO PREVENT A RECURRENCE THEY WOULD FIT THE DRAIN PLUG WITH A SPECIAL INSECT REPELLANT TIP. I CONSIDERED THIS A REOCCURRING ISSUE THAT LEXUS WAS AWARE OF AND THAT THEY HAD A FIX FOR SO I DID NOT WANT TO PUT AN INSURANCE CLAIM IN AND RISK A RATE INCREASE. I THEN ESCALATED THE ISSUE WITH LEXUS CORPORATE AND THEY SIDED WITH THE DEALER SAYING IT'S NOT COVERED UNDER WARRANTY BUT THAT THEY WOULD COVER MY COMPREHENSIVE DEDUCTIBLE (WHICH THEY DID). AFTER BACK AND FORTH WITH MY INSURANCE COMPANY THEY FINALLY APPROVED THE CLAIM (THEY INITIALLY DIDN'T WANT TO COVER THE DEALERSHIPS LABOR RATES). AFTER HAVING THE CARE FOR THREE WEEKS, THEY FINALLY BEGIN REPAIRS.

  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.

  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.

  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.

  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.

  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.

• 08/13/2023· FORWARD COLLISION AVOIDANCE,LANE DEPARTURE

  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.

  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.

  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.

  OFTEN TIMES I PRESS THE GAS PEDAL TO ACCELERATE A LITTLE AND IT'S LIKE YOU LET OFF THE GAS ENTIRELY. YOU THEN HAVE TO AGGRESSIVELY PRESS THE PEDAL DOWN TO WHICH IT REACTS WILDLY. SOMETIMES YOU BARELY TOUCH THE PEDAL AND IT TAKES OFF BUT MOST TIMES YOU GET LITTLE TO NO RESPONSE. ACCELERATION DOES NOT REACT LINEAR IN CONJUNCTION WITH THE GAS PEDAL. A SAFETY ISSUE WHEN YOU TRY AND ENTER INTO TRAFFIC.

  THE TRANSMISSION ON THIS VEHICLE IS BAD! THE DEALER KEEPS SAYING IT'S NORMAL IN THE LEARNING PHASE, BUT THERE IS NO WAY ALL OF THIS SPUTTERING AND HESITATION IS NORMAL FOR ANY VEHICLE, LET ALONE A LUXURY ONE. THE TACHOMETER JUMPS, JERKS AND SPUTTERS AS WELL IF YOU WATCH IT. THE PRE-COLLISION BREAK SYSTEM IS ALSO SEVERELY FLAWED. IT HAS BRAKED SO HARD THAT IT SCREETCHED AND NO ONE WAS EVEN AROUND ME!!!!! THIS CLEARLY ALMOST GAVE ME A HEART ATTACK THREE TIMES NOW. IT HAS HAPPENED TWICE WHEN SLOWLY BACKING OUT OF A PARKING SPOT, AND ONE TIME WHILE DRIVING DOWN THE STREET AT A NORMAL RATE OF SPEED AND NO ONE WAS AROUND ME AT ALL.

  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)
