Delayed/Hesitating Acceleration on 2022 Base, 2.3L automatic, Sasquatch

[CuseGirl69]

Since I took delivery on 7/25/22 of my 2022 Base, 4-door, 2.3L, Sasquatch, full-size Bronco I have noticed that when I add pressure to the gas pedal there is almost a delay to accelerate and most times there is a jerky or spluttering when the vehicle starts moving (very similar to water in the gas tank sensation). I live in Central NY and this has happened in very warm to a bit colder weather and when I garage it or have it parked outside. This is my first Bronco and Ford vehicle so I don't have others to compare it to but I know other vehicles we own have a very instant/responsive/smooth acceleration.

Also, many times when I first drive my Bronco that day, the lights on the dashboard (PRNDL letters) and the lights on the middle console for heating/air and other dial lights - they go very bright then dim and do that repeatedly. I have also noticed that there is no pattern to the dimming/brightening based on whether I have the Auto-Start button pressed or not or when I'm accelerating or braking and it happens regardless if I'm in normal or eco mode. The dash and middle console lights just randomly go dim then really bright. This lasts for about the first 5-10 minutes I start driving.

I have addressed this with my dealership and they say the only thing they keep seeing is a "windshield heater fault". I have an appointment for them to look at it (again) on 10/24/22. I dropped it off once already for them to look at after I experienced (3 times) pressing the gas pedal down when I'm at a complete stop and the pedal would go straight down to the floor with zero resistance and the vehicle would not move at all. I would pause and then press down the pedal again 2 or more times even until the vehicle would finally respond and lurch into accelerating and moving forward with major spluttering hesitations until it was driving forward smoothly.

This is my first post in any forum online, so any thoughts, comments and feedback would be greatly appreciated. I've really lost all joy in what I thought was the greatest vehicle I have ever purchased and was really looking forward to off-roading and just enjoying it for the amazing, iconic vehicle that it is. I'm starting to wonder if I simply got a lemon.

Sprint Booster V3 or Pedal Commander will fix the lag. Look them up.

Edit: check your battery connections as this sounds like more than standard pedal lag.

Oddly enough the forum linked me to this thread. Any chance this is what yours sounds like?

Every Ecoboost Ford I've owned does this. Even my 2.3 OBX.

Will do. Thanks.

Yeah, no sound difference or anything like that. I did try to search for my issue before doing a new post but I didn't find anything like what's happening to mine. Thanks for the info, though!

My 2.3 doesn't do this, except for the occasional "bronco buck" that the manual transmissions experience. I'd check the fuse boxbolts, make sure that your connections are tight at the battery.

Seems like an electrical/ground issue as the root cause. Especially with the backlights flickering like you described.

I have a 2 door OBX Squatch with 2.3L and I don't experience anything like this. Occasionally the take off under light throttle, maybe on a rolling start, it will be a little hesitant. However it is nothing like what you are experiencing. Sorry I can't be more help other than a data point.

I should have added that mine is an automatic in my original post. Thanks for the feedback. I will look into this as well. Thanks!

Hey there! I can look into your Bronco’s acceleration concerns on my end if you’d like. Will you send us a private message with your VIN and dealership info?

Lights will dim and get bright going into and out of shade/sun etc. Mine does this as well. On dash and radio screen. Pretty sure thats what your noticing. And if you have the sensor on dash covered with anything you will make it erratic. Just a thought.

To add more information. Nothing is ever resting on my dash - not even a pair of sunglasses or keys, nothing. When I say the dash panel is brightening/dimming...I am driving to work, broad daylight, no tunnels, etc. And, again, the lights on my middle console (the orange lights that go on when heat or air is turned on) dim and go bright almost instantaneously (no delay or fading in or out and no flickering whatsoever). There also seems to be 3 brightness settings when it does this. It starts off being dim then suddenly so bright they're like Christmas lights and it's a on/off switch sort of action...not a graduating dimming/brightening. Then, after about 5-10 minutes of driving, it settles on a medium brightness. Also, if this is just a reaction to the outside sun/clouds/covering as I'm driving, it would be way too sensitive, in my opinion...as they can change from dim to bright in a matter of 15 seconds or so at a time. Thanks for the comment!
