2010 Lexus RX Powertrain & Transmission Problems

The hybrid transmission failed at 146k and the light went on. When we took it to the dealership, they said that there was metal bits. The owner of the vehicle when into the dealership asking the dealership to set tire pressures and inspect floor mats for proper installation, they performed an inspection and inflated the tires. The owner went in and stated that the check hybrid system warning light is on. Oil pump range/performance. NOTE: no road test performed. Possible additional work needed. Transmission oil pump inoperable due to metal in fluid shorting the pump. The dealership took a fluid sample. They had found lots of metal particles present in the fluid. They recommend replacing the transmission, oil pump, cooler, cooler hoses, and clamps, flush the metal lines.

MY WIFE WAS COMING FROM WORK IN THE EARLY MORNING ON APRIL 1, 2019 AT HIGHWAY SPEED AROUND 70 TO 75MPH. ALL OF A SUDDEN SHE COULD HEAR BIG NOISE COMING OUT OF ENGINE, WARNING LIGHTS STARTED COMING ON THE DASH AND SHE COULD MANGE TO STOP THE CAR IN THE EMERGENCE LANE. SHE COULD SMELL THE OIL BURNING FROM THE FRONT. THE VEHICLE WAS TOWED TO THE AUTO SHOP AND WAS EVALUATED NEXT WEEK. THEY TOLD ME THAT ENGINE HAVE BIG HOLES IN THE FRONT, REAR AND AT THE BOTTOM. TRANSFER CASE ALSO GOT A BIG HOLE ALONG WITH THE BATTERY. THE VEHICLE HAS HAD A REGULAR OIL CHANGE AND ROUTING INSPECTION IN ALL THE PREVIOUS YEARS. I HAVE SHOWN THIS TO COUPLE OF REPAIR SHOPS AND THEY TOLD ME THAT THEY HAVE NEVER SEEN THIS KIND OF INSTANCE IN ANY VEHICLE AND ESPECIALLY LEXUS.

WHILE DRIVING AT 55 MPH STEADY ON HIGHWAY THE CAR SUDDENLY SHIFTED INTO NEUTRAL AND COASTED TO A STOP. THERE WAS NO ABNORMAL SOUND ASSOCIATED. WHILE STATIONARY I TRIED SHIFTING INTO REVERSE OR LOW GEAR WITH NO RESPONSE. I SHUT THE CAR OFF AND RESTARTED IT, THE CAR WOULD SHIFT INTO DRIVE AND RETURNED TO NORMAL OPERATION FOR A SHORT PERIOD AND THEN SHIFTED INTO NEUTRAL AGAIN. AFTER MULTIPLE START/STOPS I WAS ABLE TO GET THE CAR HOME AND HAD IT TOWED TO THE NEAREST LEXUS DEALERSHIP THE NEXT DAY FOR EVALUATION. IN THE WRONG TRAFFIC CONDITIONS (CONGESTED HIGHWAY OR UNSTEADY TERRAIN) THIS COULD HAVE BEEN A SERIOUS SAFETY CONCERN, ESPECIALLY IF MY WIFE WAS DRIVING THE VEHICLE WHEN IT HAPPENED. AFTER 2 DAYS OF NO RESPONSE I WAS TOLD THAT THE FAULT CODES INDICATED THAT I NEEDED A NEW TRANSMISSION (AT A COST OF $6900), THERE WAS NO WAY IT COULD BE REPAIRED. NO OTHER DETAILS OF THE DAMAGE TO THE TRANSMISSION WERE PROVIDED. THIS IS A 2010 LEXUS RX 350 WITH 89,500 MILES AND HAS BEEN MAINTAINED REGULARLY. FOR THIS VEHICLE, BASED ON THE MILEAGE AND CARE PUT INTO IT, I BELIEVE THERE WAS A DEFECTIVE PART IN THE TRANSMISSION BUT CANNOT VERIFY IT. I WAS NOT OFFERED ANY COMPENSATION (BECAUSE IT WAS OFFICIALLY OUT OF WARRANTY) AND HAD THE VEHICLE SERVICED (TRANSMISSION REPLACED) BY AN INDEPENDENT MAINTENANCE SHOP. THE SECOND SHOP CONFIRMED A MECHANICAL FAILURE WITHIN THE TRANSMISSION, REQUIRING REPLACEMENT.

2010 LEXUS RX350. CONSUMER HAD TRANSMISSION SHIFTER ASSEMBLY REPLACED. CONSUMER ALSO WANT TO KNOW IF HE CAN BE REIMBURSED. ACCORDING TO THE INVOICE, THE SHIFTER WOULD GET STUCK WHEN SHIFTING FROM NEUTRAL TO DRIVE. THE CONSUMER STATED ONCE THE GEAR WAS IN DRIVE, IT SLIPPED OUT SEVERAL TIMES. *JB
