I have Lc200 2018
~10k miles only

as I was going down a twisty parking ramp while ago (parking ramp was not too steep)

near the end of the parking ramp, I had to REVERSE a little so as not to hit the wall

when I returned to DRIVE the car moved a bit
and suddenly STALLED and in Ignition ON

I still have a quarter tank of fuel

I cant seem to figure out what the possible reason is
and this could be very dangerous if happened on highway speeds since the steering wheel locks out.
 
Take it to dealer.

Did it drive normally afterwards??

Could you accidentally punch the push-starter button while shifting??
 
yes it drove normally on the way home, but now I lost my trust on the car considering its quite new.. and I use this car as a family car..

I didnt accidentally hit the start/stop button
but even if i did
it will go to ACCESSORY mode


but during the stall, the car went to IGNITION ON mode...

Toyota and Lexus Recall Cars That Can Stall Abruptly While Driving

Consumer Reports shares details of the expanded Toyota and Lexus recall of about 1.8 million vehicles. The cars could stall while driving due to a faulty fuel pump. Vehicles from the 2013 and 2019 model years are included in the recall
www.consumerreports.org

There is a link to check your VIN for the recall.
 
So did the steering actually lock or did the motor just die? If the motor died but the ignition remained on the column lock shouldn't be actuated.

If the steering column locked I'd look more toward what caused the vehicle to sense ignition stop. Loose battery cable maybe?

Any other modifications to the vehicle? Remote start? Alarm?

it happened too quick was not able to check if the steering had indeed locked, cause my natural instinct was to restart the car immediately...
no mods to engine, but i did upgrade my center radio to a bigger touch screen back in 2018.

from what ive remembered
i was going down the ramp on D
then i braked,
then shifted to R to reverse back up the ramp a bit ( ramp was steep but not too steep)
then braked
then shifted to D again
car moved forward a bit (due to ramp incline) then felt a sudden small jolt (which i thought i had hit the brakes too hard but I DID NOT hit the brakes hard)
then I looked at the cluster it was at IGNITION ON and that was the time I realised engine stalled already

so i put the car on P then restarted it again


I was thinking is it possible that the fuel supply to engine was CUT because of the incline?
i had quarter tank that time

low fuel pressure?
or maybe need to change fuel filter/ pump?

ps. is moving the Shift Lever too fast from R to D and D to R be related in any way?

So I had the same thing happened to me on my 16LC. I was reversing and before I made a full stop shifted to D. Then the whole shifting got screwed up and even had problems getting into gear and stalling. Towed to the dealer as I was afraid I am destroying the transmission by even trying to drive it. They did transmission software reset and everything was perfect ever since, but I make sure I do make a full stop before shifting.

Everything stock?

I've not encountered this on the 200 - not because it necessarily does or does not, but because I don't ever rush it - but yes, putting the transmission in a gear opposite the direction of travel is a recipe for a stalled engine.

Im trying to analyse the scenario part by part
1. Going DOWN the ramp Im on D
2. but I had to Reverse so as not to hit the wall,
3. then after reversing, Im ready to move forward again.

hard to explain cause usually when we drive things happen simultaneously:
BUT IM THINKING ( in relation to your explanation)

4. maybe while still on Reverse i probably released the brakes a bit too early, like a fraction of a second early
(so gravity naturally pulled the car down the ramp, car just started to roll DOWN while still on reverse gear)

5. then almost at the same time I moved the shift lever quickly to D, BUT MAYBE it was already a split second too late cause car was already very slowly rolling down?
(i still had my foot on the brake but not full brake)

6. maybe the computer got confused, moving from R to D suddenly?

Toyota Recalls Nearly 700K Vehicles to Fix Faulty Fuel Pumps

Toyota is recalling nearly 700,000 vehicles in the U.S. because the fuel pumps can fail and cause engines to stall. That can increase the risk of a crash.

COULD THIS BE RELATED TO MY CURRENT SITUATION?

While plausible it could have been confused with quick shifting, it's very unlikely. Especially for a cruiser that's been validated and tested with tons of low speed off-roading and crawling. At extreme angles. The torque converter physically releases under certain RPM so it would be hard for software and hardware to be so wrong that it stalls a motor.

For an engine to run, 3 things: air, fuel, spark.

- Air is rarely ever an issue, especially not for a stock car
- Spark could be an issue, but usually results in some form of a CEL as the ECU can generally directly tell if an ignitor or spark event didn't happen

That leaves fuel and your suspicions would be a strong candidate.

That or a rodent has made itself comfy in yet another cruiser!
