  THE FRONT HEAD RESTRAINTS WILL NOT LOCK IN THE PROPER POSITION ON MY NEW LEXUS RX350. THEY KEEP RISING UNTIL THEY REACH THE TOP POSITION AND THEY WILL LOCK IN THAT POSITION, BUT NOT IN THE FIRST OR SECOND POSITIONS. THIS IS A SAFETY ISSUE BECAUSE I NEED THEM TO LOCK IN THE FIRST POSITION. THE DEALER SAID THEY WERE OPERATING CORRECTLY AND LEXUS SAID I SHOULD GET A SECOND OPINION FROM A DIFFERENT DEALER. HOWEVER, THE OWNER'S MANUAL ON PAGE 71 STATES: "AFTER ADJUSTING THE HEAD RESTRAINTS, PUSH DOWN ON THEM AND MAKE SURE THEY ARE LOCKED IN POSITION." THEY WILL NOT LOCK IN ANY POSITION BUT THE TOP ONE. *TR

  I HAVE BEEN A LOYAL LEXUS OWNER FOR SEVERAL YEARS AND HAVE METICULOUSLY MAINTAINED MY VEHICLE AT ONLY LEXUS DEALERSHIPS. WHILE OPERATING THE VEHICLE 10 DAYS AGO, THE OIL COOLER HOSE BURST, WHICH COULD HAVE RESULTED IN A MAJOR SAFETY ISSUE (ENGINE FAILURE/SEIZURE WHILE DRIVING) WITH CATASTROPHIC ENGINE FAILURE. LEXUS HAS KNOWN ABOUT THIS ISSUE AND HAS COVERED IT FOR MANY OTHER VEHICLES WITH 150K MILES OR LESS, HENCE THE "ENHANCED WARRANTY" ABOUT WHICH I HAD NO KNOWLEDGE. I HAVE 151K MILES AND THEY REFUSE TO COVER IT OR OFFER ANY KIND OF COMPENSATION FOR THE EXPENSE OF REPLACING THE HOSE. THEY DO NOT DEEM IT A SAFETY ISSUE, WHICH IS ABSURD FOR THE REASON STATED ABOVE. APPARENTLY THERE WAS A WARRANTY "ENHANCEMENT" OFFERED A COUPLE OF YEARS AGO, ABOUT WHICH I WAS NEVER MADE AWARE, BY LEXUS OR BY ANY OF THE TECHNICIANS WHO HAVE SERVICED MY CAR OVER THE YEARS. IF LEXUS OFFERED THIS WARRANTY, THEY CLEARLY KNEW THIS WAS A POTENTIAL ISSUE WITH THIS VEHICLE. NOW THAT THE ISSUE HAS HAPPENED TO MY CAR, THEY WON'T COVER IT, AS I'M "OUT OF WARRANTY" WITH A WARRANTY I NEVER KNEW WAS OFFERED TO ME IN THE FIRST PLACE. I WILL NEVER OWN ANOTHER LEXUS - THEY HAVE LOST MY BUSINESS AND MY TRUST,

  The contact called on behalf of her son who owns a 2010 Lexus RX350. The contact stated that she had taken her son's vehicle to the car wash. The contact stated while at a complete stop, in the carwash drive-through, the vehicle accelerated independently and the driver's side of the vehicle crashed into the wall on the left side of the carwash bay. Heavy metal structures fell on the vehicle. As a result, the windshield was shattered and the ceiling of the vehicle was bent. The air bags failed to deploy. There was no warning light illuminated. The contact sustained two large contusions below the knee of her left leg. The injured area later became swollen and bruised. The contact sought medical assistance. A police report was filed. The vehicle was towed to a tow yard. The vehicle was then towed to the contact's residence. The vehicle was not diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 12V305000 (Vehicle Speed Control). The manufacturer was notified of the failure and informed the contact that they would send a field inspector to retrieve the Event Date Recorder (EDR) in order to determine the cause of the failure. A case was opened; however, the manufacturer had not followed up with the contact. The failure mileage was approximately 250,000.

  HYBRID VEHICLE + KELSEY IGNITION = DEADLY COMBINATION. WE ACCIDENTALLY LEFT OUR 2010 LEXUS RX450H IN THE GARAGE WITH THE IGNITION "ON" AND TURNED IN FOR THE NIGHT. SINCE IT IS A HYBRID, IT MAKES NO SOUND - EVEN WHEN "RUNNING". SO WE WERE UNAWARE THE IGNITION WAS STILL ON. MUCH LATER IN THE EVENING, AFTER THE BATTERY HAD DEPLETED, THE GAS ENGINE CAME ON, FILLING OUR GARAGE WITH CARBON MONOXIDE. HAD I NOT GONE BACK OUT TO RETRIEVE SOMETHING FROM THE GARAGE AND NOTICED THAT BY THIS TIME THE CAR'S GAS ENGINE WAS RUNNING, I LIKELY WOULDN'T BE WRITING THIS E-MAIL. THIS IS A VERY DANGEROUS FLAW IN AN OTHERWISE GREAT CAR. THE TINY RED VS. GREEN LED ON THE IGNITION BUTTON IS NOT ENOUGH INDICATION THAT THE CAR IS RUNNING.

  I WAS DRIVING MY NEW LEXUS 450H (2,000 MILES) IN A FRESH LIGHT SNOW (1.5 TO 2 INCHES) IN INCLINE VILLAGE NV AT 25 MILES PER HOUR ON A SLIGHT DECLINE WHEN I DEPRESSED THE BRAKE PEDAL TO SLOW DOWN FOR A CURVE A FEW HUNDRED FEET AWAY. IT LOCKED THE WHEELS IMMEDIATELY AND AS A RESULT I HAD NO STEERING CONTROL. GIVEN THAT I HAD ENOUGH TIME TO GET MY FOOT OFF THE BRAKE BEFORE HAVING TO MAKE TURN AHEAD, I REMOVED MY FOOT FROM THE BRAKE (I HAVE BEEN DRIVING IN SNOW MY WHOLE LIFE SINCE I WAS RAISED IN CANADA) AND IT HAD NO EFFECT -- THE WHEELS REMAINED LOCKED AS I GAINED NO CONTROL OF STEERING AND THE VEHICLE CONTINUED TO SLIDE UNTIL IT HIT THE GUARD RAIL ACROSS THE STREET AS I ENTERED THE TURN AT SOME 10 TO 15 MILES AN HOUR. I AM CONVINCED THAT THE PROBLEM LIES IN THE 450H TRYING TO GENERATE POWER WHENEVER THE GAS PEDAL IS NOT DEPRESSED -- THIS IS DIFFERENT THAN MY FORMER LEXUS 400H WHICH ONLY TRIED TO GENERATE POWER WHEN THE BRAKE PEDAL IS DEPRESSED (I KNOW ABOUT THE NEW LOGIC BECAUSE THE POWER GAUGE (THAT SHOWS WHETHER THE BATTERIES ARE CHARGING OR DISCHARGING) SHOWS CHARGING WHENEVER ONE'S FOOT IS TAKEN OFF THE GAS PEDAL ON THE 450H, NOT ON THE 400H). NEEDLESS TO SAY, I IMMEDIATELY WENT TO THE LOCAL LEXUS DEALER AND TRADED THE VEHICLE FOR AN RX350 THAT WILL DRIVE LIKE A NORMAL CAR. I AM ONLY INTERESTED IN HAVING PEOPLE THAT LIVE IN HILLY SNOW CONDITIONS AVOID BUYING THE RX450H AS THEY WILL NECESSARILY HAVE THE SAME EXPERIENCE. I DO NOT HAVE VIN AT THIS TIME AS I AM AT MY SECOND HOME IN CALIFORNIA AT THIS TIME. *TR

  Pot affects 2007-2011 RX350/450= 459,285 units. 1. On Friday, [XXX], the oil cooler pipe burst on our 2010 RX350. 2. All six quarts of engine oil were lost in approximately 700 feet while traveling at 70–75 mph on the highway. 3. Massive amounts of smoke poured from the front of the vehicle & through the air vents, causing my wife & daughter to fear for their safety due to risk of a fire & smoke inhalation. 4. No warning lights appeared on the dash, meaning the vehicle could easily have been driven to engine failure had there been no smoke. 5. 2 Colorado Department of Transportation vehicles & a State Trooper stopped to be sure they were ok & monitor the risk of a fire.  8. Towed & Lexus dealership confirmed seen many 3rd gen RXs with this same issue, some with seized engines because no dash warnings were triggered.   9. Lexus updated part from RUBBER to STEE, acknowledging design flaw.   Major Safety Concerns This failure represents a serious safety risk that could have resulted in fire, injury, death, or catastrophic engine/property damage. - Oil spray on hot engine components like the headers & exhaust pipes (700-1100F) poses a legitimate fire hazard considering oil flashpoint (400-700F). - Oil sprayed onto the brakes increased the risk of loss of braking & traction control in sudden/emergency maneuvers. - Engine seizing/stop due to loss of oil could result in an accident if the vehicle stops suddenly on the highway when it seizes, loses control, or the electric steering, braking &/or other safety systems fail. - If this had occurred on a mountain descent from the Rockies into Denver or any other long descent, a fire caused by oil spraying on 700-800F brake rotors or loss of control could have occurred. - Entire underside of the vehicle is coated in oil, contaminating the rear brakes, potentially damaging wiring, solenoids, & other safety-critical components, as well as representing an additional fire risk due to oil on the exhaust pipe.   INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  There is a known issue in the form of a Warranty Policy Bulletin and I believe a recall in Canada for a faulty engine oil cooler line that was made of rubber and fails under heat (now replaced by metal lines). This happened to my daughter after a hot day and she pulled away from the driveway the next day. Almost all of the oil leaked out and we stopped the car and had it towed to a Lexus dealership. When it was inspected, it was confirmed this was the issue, and there was a noise in the engine. I have a concern that further engine problems may have resulted in a loose bearing needing compete replacement. This has yet to be confirmed, but seems consistent with the many discussion boards that mention this exact issue.

  We were 2 hours into a 9 hour drive when I noticed smoke in the rear view mirror. I continued to drive as I thought it may have been coming from another vehicle. I drove to the nearest gas station (about 3 mi) and pulled in. Upon exiting the vehicle, we found the back window and the entire back of the SUV covered in oil. There were no warning lights and no engine noises. We checked the oil and it was so low that it did not register on the dip stick. We added 2 quarts of oil which then registered on the tip of the dip stick. We then added another quart of oil and drove to a nearby service station (1/2 mi). The mechanic could not diagnose the problem since he couldn't put it on his lift (it was occupied by another vehicle). He contacted two other service stations in the area and found one less than a mile away that had a lift open. We added 2 more quarts of oil and drove to the next service station. The mechanic put the vehicle on the lift and quickly found the problem - a pin hole in the oil line. He was able to find a replacement part (not the original part as it had been discontinued) and get us up and running the same day. We were very fortunate that I noticed the smoke - if I had not noticed it and continued to drive (we were 10 minutes from driving over a bridge tunnel) it could have been catastrophic. We finished the 7 additional hours of driving that day and after being gone for a week, have now returned home (another 9 hours). The mechanic told me the part had been recalled, but when I searched this sight, I found lots of similar reports - but no recall. Coincidentally, I had had the oil changed 4 days before beginning this trip. It is surprising that there are so many reports of this incident, but no recall by Lexus.

  Driving along normally, started seeing a flashing "low oil pressure warning". Within seconds, engine started revving uncontrollably and would not make power. Was able to coast into a parking lot. On dipstick inspection, engine had lost ALL engine oil and entire car was covered in oil. Suspect that oil spilled out at some point on the road- danger to other cars. Vehicle was towed to local dealer, diagnosed as a blown oil cooler pipe, causes all engine oil to spray out in seconds. This is a known problem, addressed in Lexus Technical Service Bulletin L-SB-0154-11 and a recalled part in Canada, but not in the US. Factory part is a rubber oil line that deteriorates and bursts, Lexus has an upgraded medal line available. Service invoice can be updated once service completed if needed.

REPORTING AND ASKING BECAUSE NOT IF, BUT WHEN, LIVES ARE LOST DUE TO 'COST OF DOING BUSINESS' I'VE DONE MY PART TO MAKE A RECORD FOR THE CLASS ACTION LAWSUIT. SHAME ON LEXUS/TOYOTA.

  the rubber oil cooler hose busted/exploded on 6/03/2021 on the way home from vacation 2 hours away from home late at night with my 2 children. there were no warning lights etc. all of a sudden it started making this horrible sound, i stopped on side of rode to everything covered in oil. had to get the vehicle towed to home. the engine and all under hood was covered in oil. i see tons and tons of complaints on this issue but no recalls. i would think this is very dangerous. shouldn’t this be replaced for free and /or reimbursement. spoke with ballet lexus roswell. they were familiar with this problem but no reimbursement offered therefore vehicle is still sitting in garage undeliverable.

  Oil cooler line, rubber elbow potential failure. No notice letter from Lexus received warning of their TSB: POL.14.02 (NHTSA#: 10056509). Voluntary extended warranty coverage is expired now and no support from Lexus offered. Rubber elbow cannot be simply replaced as the newly desigend replacement is a metal elbow. Entire assembly must be replaced. Extremely expensive. Unacceptable for a flaw to endanger the engine, and possibly to cause a fire with oil spray onto a hot engine/exhaust.
