GX550 Luxury + at the dealer for a new transmission (5k miles)
- Thread starter RAVEN550

Could you provide additional details on the issue you were experiencing? When I come to slow stop, it feel a double bump. Kind of like a hard downshift just before I come to a complete stop. It happens about 25% of the time, I cant figure out what conditions trigger it and why sometimes it comes to smooth stop with no thump.

That was my exact issue. It occurred for me at least 50% of the time.

I'm not sure, but they just called back and said it needs a new transmission, which is on back order. The expected delivery date is currently the second week of November.
The truck's automatic transmission drops into 1st gear at about 3 mph. Sometimes it's more noticeable than other times.
Even when you have the transmission in "manual" mode, you can watch it automatically downshift as you slow down. If you watch the manual gear display in the heads-up display you'll see M1, M2, M3, etc. displayed. If you're up to speed on a typical road at about 45 mph and you're in M6 or M7 for example, then you slow down for a stop light but you don't manually downshift, you can see the transmission downshift on it's own as you slow down. M6, M5, M4, M3, then M2 as you get below about 10 mph, then it snaps into M1 at about 3 mph.
The downshifting is too aggressive on this truck, in my opinion. This truck doesn't "coast" well at all. It's always dragging itself to a stop with the over-aggressive downshifts, even in Eco mode. I understand that the downshifting prevents the transmission from hunting for gear and lagging in acceleration, but you'd think they'd let it sail along in a tall gear when you take your foot off the gas in Eco mode.
Is yours also the luxury?
Mine in OT model
Guess that means can happen in any model. Makes me nervous. I put my deposit down in April and I heard from the dealership yesterday now arriving November 16. Hope it’s not a lemon.
I've been paying more attention. It only happens after I've been driving about 30 minutes or so. The transmission stays in 2cnd or 3rd while I slow down for a stop, and then right when I stop (well below 3 miles) it bumps, sometimes twice, with a hard downshift to 1st. When the vehicle has been driven less than 30 minutes, the downshifts at very low speed just prior to stop are smooth and occur at higher speed not right when I stop.
I'm starting to think what I'm noticing is normal downshift behavior/programming to first gear. I tried pushing the tow/haul button next to the driver mode dial and it definitely makes that downshift thump when coming to slow stop but even more aggressively and reproducibly than when the tow/haul button is off.
We have a Luxury + and all of the sudden when I back up the car needs excessive gas pedal to move like the brakes are on. It will move eventually but requires probably 3x the gas pedal than what I would normally use. The car also slowed down considerably when I entered the driveway and again required a lot of gas to move the car forward. Is this a similar problem to what you had??I experienced an unusual jerk in my luxury+, which made me think it might be a transmission issue. The dealer confirmed after a week, and a new transmission is scheduled to arrive in mid-November (on back order).
I have a 24 gx550 OT+. I started experiencing the transmission jerk at 3000miles. Took it in and the dealer did a hard reset. The issue went away for 400miles then came back. Took it back in again, they did another reset and told me to drive it like I stole it. I guess i was babying it. 350miles later, the jerk came back. So I took it back and made it very clear to stop resetting it. I don’t have the time to bring it back every 300miles. They kept the car for 2weeks and sent out a tas case to Lexus USA. When I got it back, they told me there’s no fix at the moment and told me to go home and learn to live with the issue. I was like…..what??!!! I was confused AF.I experienced an unusual jerk in my luxury+, which made me think it might be a transmission issue.

A week later I brought it to another Lexus dealership to see if there’s any solution and second opinion. The service rept stated, “if it’s transmission issue, we will replace. Don’t worry.” I was relieved. 4 days later, I came back and they told me to wait because there’s no fix. I got so mad, I called up Lexus USA and I told them my situation. A week later, they paired me up with a case manager. She straight out told me, there isn’t any fix and is NORMAL. My issue is normal.
the next day, I called up my attorney and started a lemon law case. 2 months later we WON.
Lexus is trash! How the heck is it normal?
