Hesitation when accelerating from rolling stop

My 2018 XLE bogs down for a second or two when I accelerate from a "rolling stop" - which is about 1-4 mph. This happens in ECO, Normal, and Sport mode.

Does anyone else have this problem? It's bad enough to be dangerous and I'm hoping for a recall. The small city I live in has over 100 roundabouts where rolling stops are a part of daily driving.

Thanks.

Yep I hate the programming. It likes to stay in second gear then you have to give it some gas to get it to shift into first which makes the car lurch. Suppose you could kick it into manual and go into first earlier yourself.

Yup, can confirm several others have this issue from another thread. I constantly switch between S mode and D when coming to a stop. Thankfully with paddle shifters, even in D, I can change gears and avoid the hesitation.

In all modes, it looks like the transmission starts in fourth gear (S4 when you switch from D to S). In D, you can paddle shift the transmission down to D1 or D2 as well-I do not know what gear it equates to...I did not check when I discovered the downshift in D-mode.

Can you paddle shift it up and force the car to begin movement in 5th? This would be a + when driving on slick roads. My old LTD (3sd auto) could be forced to start in 2nd by shifting to that gear. Starting in a higher gear greatly reduced wheel spin.

Now that I have about 2000 miles on my car, it seems that the transmission has smoothed out quite a bit when accelerating from slow speeds. When I first got the car, it seemed like I had to floor it to get it to start moving. I have an XSE V6.

Thanks for the update from a V6 driver perspective ... I thought the lethargic throttle response was an I4 issue only?

Is it transmission, TPS (throttle position sensor), or CAS (Collision Avoidance System) causing the issue even though you report yours has cleaned up?

I wonder if CAS has to sign off on throttle input before you can get going?

With my V6, if you hit the gas pedal smoothly and deliberately from a rolling or full stop acceleration is generally pretty smooth. If, on the other hand you hit the pedal harder, the car tends to lurch slightly before taking off. I've also noticed that, on a hard acceleration from around 45 to 50 mph on a freeway ramp up to a full speed of 70-75 mph, there's a hesitation and then, voom, the revs rise rapidly and you're flying. It seems to me that a transmission software update with a transmission programming modification could resolve much of this.

I also have this issue. I have a XSE V6 with 2800 miles on it. Since i got it the car will always be smooth with light throttle in normal mode. If i hit the gas a little harder it seems like it hesitate until a high rpm. Sport mode seems pretty descent without much of a hesitation. I also noticed when coming to a dead stop 80% of the time the transmission will drop hard into first gear. Kinda annoying. I hope their will be a transmission update soon for the car.

I had this same issue but everything seems to be smoothing out, I noticed it stop happening after the first oil change, I have about 7,500 Miles on now and I don't notice this issue at all anymore.

I just went over 1700 miles on my Camry and noticed today that starts from a complete or rolling stop were smoother. Going from 65 to 75 or 80 also seems smoother. There doesn't appear to be the previous abrupt gear change and roaring acceleration. Hopefully that will now be the norm with further room for improvement.

I have a 2018 SE ... same issue ... dealer looked at me with that "you are a PITA" look and told me to go talk to the salesperson and see if she had any other customers with that complaint ... sort of like if the answer was no then I should just leave ...

I am hopeful that as others have stated here the comp will learn my driving habits and resolve, I only have 800 miles on the car so far.

Have others seen improvement over time?

My '18 SE is having similar issue.
I noticed at speed below 25MPH - sometime it lost power for a couple seconds, then suddenly kick in (jerking) hard like someone hit me in the rear. It happens randomly, especially when I turn. My Camry is at ~2800 miles now.

I had this same issue on my '17 tacoma, the dealer updated the transmission firmware and it went away. Hopefully Toyota will release a firmware update for the transmission.

I've own many toyota vehicles in the past 25+ years. Recently noticed toyota quality control is going downhill on newer vehicles.

Plus it now takes Toyota around 3 years to work out first year model redesign bugs. The cosmetic and mechanical bugs in the all new 2012 Camry, for example, weren't worked out until the 2015 model year. It took Toyota that long to make the car feel refined, acceptably quiet and highly reliable. Ditto in regard to the all new 2013 Avalon - it's hard ride comfort problem, falling headliners and other ills weren't fixed until the 2016 model year. Ditto in regard to the all new 2016 Tacoma - even the 2018's still do not yet exhibit responsive and refined engine/transmission behavior.

I took my '18 Camry in today after feeling a very hard "shift shock" on two separate occasions yesterday. Honestly, it felt like someone rear ended me.

The dealership did confirm my concerns after driving it. My service advisor said there is a software update available to correct the issue. Unfortunately, it took six hours to complete because they couldn't locate the serial number for my transmission. The service technician apparently had to contact a Toyota engineer to get everything squared away.

Long story short, I tested it myself on the way home, and the problem was gone. The transmission doesn't feel lethargic and shifts much smoother now.

Don't mean to just add more of the same, but I have a 2018 XSE I4 that we got in October of 2017. It is having the same issues as described even after 5k. I have read and reviewed the T-SB-0330-17 and my vin does apply. Hopefully this will get it sorted out because I absolutely love this car...except when taking off from rolling stops lol

Yea Im not totally sold on the TSB fixing it. It seems like first gear is too steep to be starting off midway like when you do a rolling start which causes the "slam" feeling from the torque. Not much they can change about that except make it hold second to a lower vehicle speed, but that's changing the way the car was engineered/designed to operate.

Is your Camry 2018 four or six cylinder? I don't own a Camry yet; was considering buying a 2018 or 19 model, but all these complaints about the SHIFTING has me concerned. My understanding is the torque converter is only used in FIRST GEAR, not 2nd thru 8th. Would a torque converter have some "give" and not a SLAM? Seems downshifting to any gear besides 1st might give a SLAM.
