Driveshaft Problems of Lexus RX

Roaring noise appeared in 2020 upon acceleration of the vehicle from the rear differential that became louder overtime which would not be mentioned in the multiple inspection reports even when pointed to the service representatives ;instead one of them verbally demanded $750 for the diagnostics and $5000 for the repairs! the other gave an invoice estimate of $2000 for the part and $800 for the labor on 04feb2021 as attached. Toyota has issues a technical bulletin t-sb-0080-13 rev 1 dated June 14, 2013 titled "rear differential coupling growl noise" available online, indicating the company is aware of the problem in the powertrain's electro magnetic coupling (that connects to the drive shaft and sits in front of rear differential) Lexus part # 41303-48010 which is also used in 2006-09 rav 4 a with different Toyota part number. While this electro magnet coupling is listed in their bulletin as used in rav4 2006-12 4wd, it did cause an identical growling noise in my 2010 Lexus Rx 350 awd which was notified to Lexus corporate hq via an online complaint on 08feb21, whose corporate representative called same day to resolve it without resolution to date despite a firm promise of call back with resolution plan on 12feb21! Lexus parts department in both local dealerships, when specifically asked to pin point parts required to repair the coupling, declined to provide any information!when asked to sell parts # 90363-95003 & 90363-65004 they declined and said "coupling" & its "parts/bearings" are 'out of stock' in the united states and recommended me instead to sell my functional and maintained vehicle as soon as possible! bearing failure during driving may potentially result in fatal accidents and put life and safety of vehicle occupants and o! manufacturers should alert customers about any such defects in the design of such parts and propose resolution in a timely fashion.

Early failure of transmission after following maintenance schedule and changing fluid every 30k miles. Transmission failed while drive in the desert 75 miles west of salt lake city, utah. Transmission replaced at roseville Lexus, the replacement would fail to go into drive when the gas pedal was push after stopping causing many near collisions from the rear during heavy traffic, second transmission was replaced finally, but the stabilizer bar mounts were left disconnected and rubbing on the brake lines and drive shaft. Incidentally the first replacement transmission was missing three bolts which attached it to the engine. The quality of work by this dealership was very poor and unsafe to the owner. The second transmission replacement was poorly done and the drive shaft came out on the right side tearing the seal and leaving fluid everywhere. This dealership caused more damage to the vehicle and left it in unsafe condition which could have caused injury to the occupants.
