Default Transmission Issues Anyone Else?

So this has happened twice now in the last couple days... I need to take the car in but was wondering if anyone else has experienced this... I think its different from the hesitation issues which I have as well.

On the freeway twice, the transmission seems to have gotten stuck on a low gear and wouldnt change... the rpms got to around 4k and then jumped awkwardly down like it was skipping gears. I had this same thing happen on my old accord before the transmission blew...

For what its worth, its a 350 f sport with 2800 miles.

2) what transmission mode were you?

3) Did use drcc?

I was in Sport mode, the transmission was in drive, DRCC was not on.

I think my description above is a bit off... it will get stuck around 4k rpm and the engine will be reving hard, i would have to let go of the gas, then tap it again, and it drops out of the gear its stuck on then works ok again.

I haven't had that issue, but I took a road trip yesterday and notices some hard shifts while on the interstate at 70 MPH. When the car would downshift to go up hill or pass the car seems to shudder a little then shift very harshly. I am going to take in soon to have checked out. I have noticed the behavior you had only with ddcc on.

get it checked out. make sure you record a video of it if they can't replicate it at the dealer which happens 99% of the time

Sounds like normal transmission logic in sport mode. While it tries its hardest, the transmission AI cannot always accurately predict what the driver is doing. What you're describing occurs when you jab the throttle and let off quickly, then get back on it. It'll hold the gear awkwardly long, anticipating you're attempting to full throttle. Seems like you caught the transmission in one of these scenarios.

Yup same problem and loss of power. stopped and it all reset. Another 30 minutes driving and ICS failure AWD locked out. Towed to dealer reset and picked up vehicle and 30 minutes on road transmission stuck in 6th and low power. Stopped and it reset. Towed back to garage and they want to put a new transmission in will take 2 months to get in from Japan. This a repeat of issues that happened in July. RX350 Fsport 12000km.
Codes said d and g solenoids stuck.

yes but I am going for a replacement this the fourth tow in in 9 months. Very unsettling and no trust in the vehicle. It does seem this is rather unusual.

Canada does not have a lemon law but I am trusting that Lexus with all its messaging about customer satisfaction will replace the vehicle. Will find out in the next couple of days.

This exact thing happened to me the other day when I was on cruise control on my 2016 RX350. I was either going down or uphill slightly when the engine revved to over 4000 rpm. Then after a few seconds it went back down to normal range. I have no idea why it did this but it did it a couple of times on that drive. I had Lexus look at it and they said itís normal. Whatever. Starting to hate this car with all of the issues I am having.

I could see if you're going uphill and the transmission downshifts to maintain the set speed, but going to 4k when going downhill.....no way that's normal.
