Acceleration Hesitation from a Complete Stop

Hello. I have a 2023 Limited in the non-hybrid version and wondering if anyone is seeing this. From a stop there is a noticeable delay sometimes from the time I press the gas pedal to the time the truck actually starts moving. It isn't turbo lag, but a hesitation for the truck to actually start moving forward. I needed to move quickly yesterday to get through a gap in traffic from a stop sign and it was like the truck just didn't move for a moment when I pressed the pedal and it make the situation much more dicey.

Is this something that anyone else is seeing? Is there a fix?

Thank you!

 

Welcome aboard sir, I don’t not personally own a 3rd Gen but have seen no fewer than 100 posts about this issue on this forum. I believe there is a tsb with a computer flash / update that addresses this problem. Read around in the 3rd Gen section, you’re bound to see it mentioned.

 

Thank you. Something must have been wrong with my search criteria. I promise I did one!

 

I'll save you some time. There is a TCM update TSB that some of us feel remedied the issue temporarily but the problem comes back after a few hundred miles or so.

 

Bummer. Thanks for the info!

 

I had the TSB done also and hesitation, especially when cold outside or after first start of the day has returned. I’m now wondering if it is a cold start or cold temperature mixture issue. It almost acts like it leans out and is momentarily starved for fuel. Doesn’t matter how far you push the gas pedal. Then it catches up and lurches forward. A combination that could be unsafe and cause an accident. It only happens when you hit the gas quickly. Toyota please look into this further.

 

This is 100% my exact problem. I had time to make the gap, but the truck hesitated and made it a closer call than it should have been. I have to go in for my 5,000 mile here in a couple of weeks, and am going to bring it up. Thanks!

 

I have a '23 1794 TRD and had the hesitation a few times but took it in for the TSB anyway. After the TSB it seemed like it still did the hesitation, but some 1500 miles later I would say it's nearly gone and when it does show up it's no worse than I've had on other vehicles when-and-if they have a hard time deciding on a gear during a rolling stop with acceleration. I've learned to come to a complete stop more often than not and this issue is gone from my perspective. The post-TSB result seems to vary depending on the vehicle...it's a crap shoot what long term result you'll get.

 

Mine (non-hybrid) was built two weeks ago, with less than 400 miles on it. This week I experienced the exact thing you guys are describing trying to merge into traffic from a stop at an intersection.

 

Interesting that this is still happening with 23's.

And still isolated to non-hybrids? I swear that's the issue. I've said it before, but it's as if the throttle is expecting the electric motor to get the truck going before it kicks the engine in.

 

You speak the truth! I had the TSB done, which also addressed the “clunk” at start up, according to the dealership. While the clunk never returned, 7,000 miles later, the hesitation from a stop is back with a vengeance.

 

I have a 23 Platinum with about 1000 miles and I have noticed the hesitation as well. I kinda feather the gas pedal a little and it helps.

 

I have the TRD Pro and feel it happens to me. I searched for a thread and found this one.

It isn't bad but something i didn't have with my tacoma. It almost seems like the computer can't decide whether to use the electric or turbos, once it decides it moves out.

 

Yup the clunking noise went away but I still get the hesitation from a rolling stop at a yield sign

 

What is the number for that TSB? Also is the engine revving up while the truck is hesitating to move?

 

Mine had the TSB done and I almost got T boned this week. I was turning left crossing two very busy lanes on four lane urban road. Goosed it and nothing, rolled ten feet into cross traffic and dead pedal. Floored it and nothing. Fortunately the two cars barreling toward me saw me and slammed on their brakes. Pumped gas and nothing. Motor was running but nothing. After a few seconds let off gas completely and gently feathered the pedal. Had power this time and a few waving fists and the bird from the other drivers. The TSB has not solved this dangerous problem TOYOTA. Please figure this out before someone gets hurt. 22 Non hybrid Limited 4x4 12000 miles.

 

You guys need an in-cabin cam to show you jammed on gas and getting t-boned to post on youtube, I am sure that will get corporates attention real quick.

 

I have the oem dash cam. Good idea, have to see if it picked it up

 

Sport or Tow/Haul mode helps a bunch. I use Sport driving in heavy traffic. The TSB did help my truck. Feathering the throttle as others said also helps.

 

What I have observed is going up my drive way 3 degree incline cold truck will shift in to 2nd gear and as I almost get to the top the truck has to downshift as I just lessen the throttle but not completely let off it losses throttle because it's downshifting into first which seams slower when it's cold. I can do this consistently so I say in my instance it's the transmission logic pulling throttle to downshift smoothly. My past 2018 lariat would just slam into first and the whole truck would lurch, shutter and clank from the drives shaft. Also the Ford would slam into first sometimes coming to a stop and again clank from the drive train. I have not experienced a hesitation from a full stop unless I do not come to a full stop then it will if it hasn't completed going into first gear.

 

I have the same problem as others. From a dead stop my track hesitates. Today while turning I almost got slammed into because the truck did not go. I have a 2023 Tundra 1794 edition and have 1750 miles on it. The issue happens every day but is getting worse.

 

I need you to go on Amazon or even best buy and get yourself a cheapo dash cam ~$100. Mount it to the rear window (do not roll it down) from the passenger side facing you the driver, and possibly where it can see your feet and pedals if possible. You can just have the power cable running from the USB outlet in the rear if you got it.

Seriously, if this is happening everyday then you need to show how dangerous it is so Toyota will recognize and address.

 

It started happening to me these last 2 days, first time there was no cars while making a left out of a parking lot but the second time that lag was a close one. Driving a Platinum Hybrid

 

Oh thank god I came across this thread. I’ve had my 23 in twice for this, the first time was over 10 days, the second was a few. They claim they cannot recreate the problems so they won’t look into it further.

Can we all agree there are two different issues we’re experiencing?

1) The unsafe stall, some are calling it a hesitation. From a stop you get about 10-15 ft forward before the pedal becomes inoperable for about 2 full seconds before it slowly comes back to life. I along with others was trying to merge into traffic and if the cross traffic hadn’t been paying attention it would have been a 45 mph tbone wreck. I cannot isolate what causes the issue but it’s intermittent at best. Note that when I went in there was no active tsb; it was handled before I purchase the truck about 2 months ago, 2000 miles.

2) Also a hesitation but as FI460 described it's as if the throttle is expecting an electric motor to get the truck going before it kicks the engine in. I liken it to the rpm’s climbing from a stop but the engine just isn’t responding, it hesitates and eventually begins to move but it’s at a much higher rpm than it needs to be. Like the transmission isn’t engaging early enough?

Anything else anyone would add? I’d like to clean this up and use this in my next attempt to get help from Toyota.

I just can’t believe that they can say nothing is going on?! It shouldn’t take someone getting hurt or killed because they don’t want to acknowledge more issues with these darn trucks.


And for those of you who think we’re a bunch of whiners be thankful your truck is operating the way it should. What we’re experiencing is very abnormal. It leaves a pit in my stomach considering how much we’ve paid just to not get assistance.

 

Has anyone experiencing this lag, tried to use the manual shifting? you can pull the transmission into 2nd and when you are ready to take off, it seems to go right away. I was pulling about 2,500 lbs (un-braked trailer) and rather than starting in 3rd, I used tow mode and shifted into 2nd or even 1st gear if I was starting on an uphill. The truck did great with no issues. Just remember to shift up once you get going.

I think the "D" allows the transmission to make the decision of which gear to be in, so it may be hunting for the correct gear.

I had to move about 10 loads of over the course of a few weeks and I would use the manual mode to start and once I was going, I would pop it back into "D".

 

I've experienced this also. The strange thing is it's not every time.

 

Rolling stops is where it gets me the most was fixed but then came back

 

All, please get dashcams. If you get into a bad accident because of this issue, you may have a strong claim against Toyota if you have dashcam proof

 

Same truck as you and I do not have this delay. (in any mode) Some with MY’22 say 2-3 seconds. Seems random and not across the board.

 

Yeah I got the Toyota dash cam with mine now I’m just looking for options for rear facing one
