The Lexus TX 500h is equipped with a 6-speed sequential-shift automatic transmission, which is paired with the Lexus DIRECT4 all-wheel drive system. This setup utilizes a 2.4-liter turbocharged hybrid powertrain to deliver 366 horsepower and 406 lb-ft of torque. During many occasions, the transmission on the 2026 Lexus TX500h would shudder during acceleration or deacceleration. I noticed it happening around 25-40mph mostly and it has happened more than once. I have demonstrated the issue to the dealer on Wed, May 20th around 10:15am Pacific but they didn't know how to address the issue. I did a ride along with the service tech from Lexus of Pleasanton and it happened again during acceleration. The dealer noted that there were no error code when they scanned the system and no observed leaks. I have a video clip but was unable to upload it. The issue with transmission shift thump when this issue happen feels like the transmission locked up. It would shake the vehicle and lose power while accelerating before it starts to gain power back in 1-2 seconds. This causes a safety issue since that pause in acceleration thus this can be dangerous while merging onto a freeway or areas with lots of traffic. I noticed the same issue on some occasions, it would shake during deceleration as well. This issue is intermittent. Maybe Lexus/Toyota can address this with the transmission shifting update. IMO, It's a safety issue that needs to be looked and fixed by Lexus/Toyota. Dealer asked me to come back only. They reset my information screen to address a sliding driving issue where when the power is turned off on the vehicle the seats will go back and immediately go forward.
