2018 Lexus LS Complaint Log

VIN: [XXX] Current Mileage: 70,440 Vehicle: 2018 Lexus LS500 In November 2021, I purchased this vehicle with approximately 19,000 miles. Routine maintenance was performed every 7,500 miles. At approximately 44,000 miles (in 2023), the vehicle experienced severe engine failure following warning lights for Parking Support Brake Malfunction, Secondary Collision Brake System Malfunction, Check Engine, Reduced Engine Power, and Traction Control Off. The vehicle lost power and stalled. The engine began emitting smoke and was replaced under manufacturer warranty in March 2024 at a Lexus dealership. The repair exceeded $50,000 and included a new engine block and related components. Shortly after receiving the vehicle back, additional major failures occurred: Fuel pump failure resulting in “Reduced Engine Power” and restricted speed (~20 mph). The pump was replaced under warranty (approx. $4,600 cost). Brake system failure occurring three days after that repair (January 2024). As of October 28, 2025, the vehicle has again failed and is currently at Christian Brothers Automotive with the following findings: “Fuel pressure sensor located under the intake manifold is actively leaking fuel when the engine is running. This creates a fire hazard and can affect engine performance and fuel pressure regulation. Immediate attention required.” This repeated pattern of engine and fuel-system failures within a short period after a full engine replacement raises serious concerns about component reliability, workmanship, and safety. Fuel leakage near the intake manifold poses a significant fire risk. There are currently no open recalls addressing this defect. I request that NHTSA investigate potential defects or systemic issues in the engine or fuel-delivery systems of the 2018 Lexus LS500, as these failures appear premature, hazardous, and recurrent despite dealer and manufacturer repairs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Recently I purchased a CPO Lexus 2018 LS 500. I realized I am not able to enter Coordinate in the GPS Navigation system. Lexus took away the most import tool (The coordinate Entry) in navigation system away, this make the navigation system useless and easy to get lost when cell service not available especially in and around State and Nation Park area.

Large lump/lumps on the lower left / bottom portion of the driver's seat, protruding from the seat bottom closest to the lower bolster. As a direct result my left leg loses its circulation, it causes numbness and muscle pain in thigh and groin due to this. Regardless of seat adjustment the lump / imperfection in the seat cushion is present. This can become dangerous during longer drives and trips. According to the Lexus forums this is a known issue in the 2018-2024 LS500 that Lexus is apparently aware of but has not resolved or seriously looked into. My Lexus service advisor admitted that she has heard of this problem from other LS500 owners and said that the issue has been reported to Lexus. Despite this known issue, no technical service bulletin has been issued by Lexus and no corrective action has taken place. The imperfection in the seat can create a safety issue during trips due to it causing numbness, pain and discomfort in the leg. This is not an issue one would expect in owning a $100K plus vehicle.

All 4 tires have tread wear on the inner side. Took it to lexus they said no remedy is available ended up selling the car. May cause slip and accident

The vehicle exhibited 3 episodes of premature battery failure. Mileage of the vehicle is 6000 miles. Without any warning the car would just not start from a gas pump or such locations in the middle of the road. This is a dangerous problem because there was no warning that the battery is running low or there is any problem. Car runs 100 miles every day. Lexis dealership diagnosed battery failure and replace the battery but this is a safety issue particularly because it happens in the middle of the night when you are driving in a remote location and gas pumps tell you to switch off engine before filling And there is no warning sign to indicate that there is a problem with the battery THIS SHOULD BE INVESTIGATED AS A SAFETY ISSUE

VEHICLE HESITATES WHILE DRIVING. RECALL ANNOUNCED TO US 1/20/2020. HAVE ATTEMPTED NUMEROUS TIMES TO HAVE DEALERSHIP DO THE FREE RECALL REPAIR. EVEN WHILE THERE FOR OIL CHANGES AND REGULAR SERVICES THROUGHOUT THIS YEAR. HAVE BEEN TOLD EACH TIME THEY NEED TO ORDER THE PART AND THEY WILL CALL ME. 10 MONTHS OF THIS NOW AND CAR IS UNSAFE- THEY KEEP STALLING ON DOING THE REPAIR THAT IS A SAFETY RISK FOR MYSELF AND FAMILY. WANT THIS DOCUMENTED IF SOMETHING HAPPENS TO US AND WE HAVE AN INJURY OR DEATH BECAUSE THE CAR HAS BEEN HESITATING AND THEY CONTINUE TO TELL US THEY DON'T HAVE THE FUEL PUMP TO DO THE REPAIR.

TL* THE CONTACT OWNS A 2018 LEXUS LS. THE CONTACT STATED THAT THE VEHICLE WAS EQUIPPED WITH A PRE-COLLISION SYSTEM, WHICH WAS SUPPOSED TO AID IN PREVENTING A CRASH. IN THE EVENT OF A CRASH, IT RELEASED THE HOOD OF THE VEHICLE. WHILE DRIVING APPROXIMATELY 45 MPH, THE CONTACT WAS CUT OFF BY ANOTHER VEHICLE. THE CONTACT DEPRESSED THE BRAKE PEDAL IMMEDIATELY AND THE PRE-COLLISION SYSTEM ACTIVATED. AS A RESULT, THE HOOD OF THE VEHICLE RELEASED. THE CONTACT TOOK THE VEHICLE TO JIM HUDSON LEXUS (LOCATED AT 3410 WASHINGTON RD, AUGUSTA, GA 30907, 706-650-9999) AND WAS INFORMED THAT THE DIAGNOSTIC BOX INDICATED THAT A COLLISION WAS NOT DETECTED. THE DEALER DIAGNOSED THAT THE VEHICLE'S PRE-COLLISION SYSTEM NEEDED TO BE REPROGRAMMED AND THE ACTUATORS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND A CASE WAS OPENED. THE MANUFACTURER STATED THAT THEY WOULD NOT BE ABLE TO PERFORM THE REPAIR. THE APPROXIMATE FAILURE MILEAGE WAS 6,300. *LN THE MANUFACTURER STATED THE PEDESTRIAN HOOD POP UP FEATURE ACTIVATED AS DESIGNED.*JB

THE COLLISION AVOIDANCE SYSTEM BLOWS FUSES AND STOPS WORKING, BUT THE LIGHT ON THE DASH CONTINUES TO INDICATE THAT EVERYTHING IS WORKING. IN OTHER WORDS, THERE IS NO WAY TO LEARN THAT THE COLLISION SYSTEM IS OFFLINE UNLESS YOU'RE WILLING TO SIMULATE A NEAR CERTAIN COLLISION (WHICH I DID WITH THE DEALER IN MY CAR AND HE FINALLY ACKNOWLEDGED THE PROBLEM), OR HAVING AN ACTUAL ACCIDENT. THIS IS CLEARLY A DESIGN FLAW. IF THE FUSE IS BLOWN, OBVIOUSLY THE SYSTEM SHOULD SHOW AN ERROR WHEN IT'S ENGAGED - NOT A GREEN INDICATOR.

APEAL AGAINST THE RECALL DONE BY LEXUS TOYOTA ON MAY 16TH, 2019, I TOOK MY CAR LEXUS 2018 LS 500 TO THE DEALER, LEXUS OF WOODLAND HILLS, WHERE I BOUGHT IT, FOR BEING RECALLED BY THE COMPANY. (NHTSA RECALL NO. 19V-134) AFTER RECALL DEFECTS WERE FIXED, I DROVE ABOUT 4,000 MILES AND TOOK THE CAR BACK TO THE DEALER FOR MAINTENANCE. AT THIS TIME, TREMENDOUS NUMBER OF DEEP LARGE SCRAPES ON ALL FOUR TIRES, WHICH I HAD NEVER SEEN IN THE ENTIRE DRIVING EXPERIENCE OF MY LIFE WERE POINTED OUT BY THE DEALER. THE DEALER VIOLENTLY INSISTED ON THE SCRAPES WERE NOT CAUSED BY THE DEFECTS. AFTER TREMENDOUS ARGUMENT, THE DEALER WROTE, 'DIAGNOSTICS IS REQUIRED TO DETERMINE THE RECOMMENDED CORRECTION FOR YOUR CONCERN.' THE CAR ALSO HAS STABILITY PROBLEM. FROM THE BEGINNING, IT LACKS STABILITY COMPARED WITH LS460 TRADED-IN. I VISITED LEXUS OF GLENDALE, SANTA MONICA, AND THOUSAND OAKS. THEY WERE SURPRISED AT CONDITION OF SCRAPES, BUT THEY WITHHELD COMMENT. I HAD NO CHOICE, BUT TO APPEAL TO LEXUS OF TOYOTA. I CONTACTED; <DATE> <CONTACTED TO THE PERSON OF..> <BY > 10/02/19 TOYOTA CUSTOMER SERVICE REP.

I AM FILING THIS COMPLAINT TODAY WITH LEXUS CORPORATION BECAUSE BOTH MY DEALERSHIP, NEW COUNTRY LEXUS OF LATHAM, AND LEXUS CORPORATION HAVE CHOSEN TO IGNORE THE DANGER THEY HAVE PLACED MYSELF AND MY FAMILY. I HAVE PURCHASED THREE LEXUS' OVER THE YEARS FROM NEW COUNTRY LEXUS AND AM VERY DISAPPOINTED IN THE SERVICE FROM BOTH MY DEALER AND LEXUS CORPORATION. I AM DISAPPOINTED THAT NEW COUNTRY AND LEXUS CORPORATION WOULD PUT ME AND MY FAMILY AT RISK OF INJURY AND/OR DEATH. PARTICULARLY IN LIGHT OF THE FACT THAT I HAVE REACHED OUT TWICE TO MY DEALERSHIP AND THREE TIMES TO LEXUS CORPORATION. THEREFORE, I AM DOCUMENTING MY CONCERNS IN THE EVENT OF A SERIOUS INJURY OR DEATH OCCURRING IN WHICH I WILL HOLD BOTH LEXUS CORPORATION AND NEW COUNTRY LEXUS RESPONSIBLE. ON FEBRUARY 26, 2019 A SAFETY RECALL WAS ANNOUNCED REGARDING CERTAIN RUN-FLAT TIRES WHICH INCLUDED MY NEW VEHICLE, 2018 LS 500. I DID NOT RECEIVE THIS RECALL NOTICE UNTIL FRIDAY MARCH 29, 2019. THE PREVIOUS WEEK, ON MARCH 24TH, I WAS ON MY WAY TO KENNEDY AIRPORT IN NEW YORK CITY AND HAD A BLOW-OUT CROSSING THE GEORGE WASHINGTON BRIDGE. THE SIDE WALL OF MY FRONT DRIVER SIDE TIRE HAD BLOWN OUT (PICTURE ATTACHED). THIS ALMOST CAUSED ME TO VEER INTO TRAFFIC WHICH I FORTUNATELY WAS ABLE TO AVOID. I WAS EVENTUALLY TOWED TO A 24HR TIRE REPAIR STATION WHERE A REPLACEMENT TIRE WAS PUT ON THE VEHICLE. THE TOWING CHARGE AND NEW TIRE COST ME $400 WHICH LEXUS HAS REFUNDED ME A CHECK FOR $400. TO THIS DAY I CONTINUE TO BE TOLD THE TIRES ARE ON BACK ORDER AND I AM STILL DRIVING ON DEFECTIVE TIRES. IT HAS BEEN NEARLY 6 MONTHS.
