Had to have the transmission replaced in my TX500h at 200 miles and the vehicle is back at the dealership now with a little over 700 miles as RPM's stay at 3500 randomly. I wanted to see if anybody else is experiencing these issues? Very disappointed with the reliability of the TX that I purchased.

Wow. I can understand why you are disappointed. I once bought a new 1998 Honda Accord, and it had a transmission that failed right out of the gate. It also had a loose screw rolling around inside of the steering wheel when I bought it, and the screws that attached the fenders to the wheel wells were ALL missing. I guess my car was made by hung over/disgruntled employees.

This is the reason I never purchase the first production year of any car and a little leery of the 2nd year. Workmanship and quality slipping.

Probably a good policy. I previously had a 2011 LS 460 (I drove it 160k miles), and before that a 2005 Toyota Avalon, which my daughter wrecked in 2021.

I seem to have a decent specimen of the 2024 TX 350, but we'll see what happens.

Same here but I just knocked on wood and drank a 6 pack

I hope yours works out for you as well!

Mine has 21,000 miles, and it’s in at the manufacturer right now with a transmission concern. It shifts abruptly or hard between first and second gear. It’s been there 2 days. Additionally, the middle row captain seat has a rattle, and there is a coolant leak. All of that said, I love the car, just need to get a few things sorted out.

My 350 shifts from 1st to second after very little acceleration, and takes more acceleration to progress to higher gears.

are you in a 500h or are you in a 350? I have had no trans issues at all with my 350 and drive it like I stole it...

I had a rattle on the rear passenger seat. it was the seat back incline adjustment vibrating against the side seat trim. I threw some loop side (velcro) behind the handle on both sides (left and right seats) and haven't heard anything since.

what is the story with the coolant leak? where is it coming from?

in sport mode it will hang on to gears longer. in normal or eco it will essentially short shift for fuel economy reasons. I have no complaints on the transmission after 12K miles.

This has to do with the 500h, GH max and also relates to RX500h and Tacoma max as well. There cases where the torque convertor is surged with power in which the transmission can't take it and fails. It may also be felt when you put it in reverse, as it is holding the power back between hybrid and gas. Unfortunately it seems to be complete design flaw with transmission, in which there fix is to just replace transmission as this case isn't always duplicated. There also rumors of them to soon do TSB to detune some of torque to avoid that much torque or power going to transmission.

Best case is you burn out the torque convertor prior to transmission there is already TSB on that for RX500h, not sure about TX or GH/Tacoma
