Hybrid SHUDDER Test - Please Try

[MakinDoForNow]

I don't think my hybrid shudders, but I have an occasional loud thump/knock that sounds like someone bangs a fender with a fist. Happens about 1x-2x times per week when I'm slow rolling into like a driveway or parking spot. Not accelerating, not really braking, but foot on the brake pedal. Scared the crap out of me the first few times because I thought I hit something! I don't feel the brakes grab coincident with the sound, so I don't think it's "grabby brakes." I switched display modes to see if it's happening in a switch from charging/electric/hybrid.

I also slowly drive into tight parking area into my garage while in creep mode and experienced the banging sometimes but not always grabby brake. It appears to me that with foot lightly on brake but not enough to activate the hydraulic nor the Regen braking that after several seconds probably varying with speed no matter how slow, the system determines that you want the hydraulic brakes applied and does so with great vigor. So do not rest foot on pedal no matter how lightly you can just keep it off the pedal. If you activate Low and use it while creeping the hydraulic/Regen interaction is much different. Due to this observation I believe some improvement could be accomplished with programming. The banging is so loud that I cannot believe that it would be cause directly by the brake pads but possibly by some interaction by electric drive motor /ecvt/planetary/ damper interaction while planetary is adjusting torque distribution. ????

I always wonder if anyone ever hears back from Ford when they ask for the vin. It would be nice if they would offer a solution. But it's always the same. Give us your vin.

But the software patches never really fixed the brakes so.....

Is this because SOFTWARE can't fix a HARDWARE problem?

Yeah, that sucks.

You have to ease into the throttle during the battery/gas transition. I’d you jam on the gas, you may experience a slight shudder.

Hi all!

Some 2023 Maverick vehicles may exhibit a shudder or vibration when the vehicle is braking at 15 mph or below, when the gas engine shuts down and the vehicle is operating in electric mode only. This may be due to the software in the powertrain control module (PCM). We've recently released TSB-23-2209 which instructs Ford dealers to install revised software into the PCM to resolve the engine shudder concern. This TSB only addresses 2023 MY, however we are finishing testing for 2022 MY and will re-publish the TSB at that time. The dealer will need to inspect your vehicle to diagnose the concern and determine if your issue is related to this TSB. As a reminder, you can find more TSB information for your VIN, make and MY at https://www.ford.com/support/ and https://www.ford.ca/support/?gnav=header-support. Please let us know how your Maverick feels with the new software.

Good to know.

But there are also MECHANICAL shudder /ratte/clank going on in many 2022 at engine shut down.

Can you confirm this is related to and resolved via "damper" replacement?

I have the same thing going on

It's the engine/transmission cluch-damper.

Like a lot of you m Mac suffers from the shudder issue. Happens very often letting off the accelerator. Happened the other day when I was STOPPED letting a pedestrian pass. The typical shudder 'fix' is to blip the throttle, but since there was a human in front of me...dangerous...

I've done some testing to see what makes it worse or better. If you have time please try these things:
1) Change MODE - I never have shuddering in SPORT mode and accordingly it is worst in eco mode.
2) Turn Off HVAC - in just a few days of testing if HVAC is OFF (i.e. no heat or AC) shuddering does not occur.

No shuddering on my hybrid. Yet

I don't think its common.

And I don't think it is rare.

Let's make a SWAG.

25,000 users on this site.
Lets assume 10,000 are Hybrid owners.
10 reported cases of a defective damper.

Might affect 1 in 1000 builds.

I’ve had mine since January and have noticed no shudder. The transitions are seamless.

 

[Bobbydontchaknow]

Have you had this fixed or is there no fix?

 

[BluegrassNbass]

No idea what this shutter is. Hybrid and i use ac. Mine doesn't do whatever this is.
