Late 2023 build hybrid shudder

It's like 1 in 25,000 units.

Yep, mine did a sort of rumble strip shudder during braking a month ago. I glanced down and saw the ICE hadn't warmed up much and assumed it was a rough coordination event between the engine, and eCVT. Hasn't done it since. Mine is a 9/23 build.

On a related noted; I have noticed the ICE can have a quite a lumpy "cold high idle" when the PCM decides to start it, to charge the HV battery. Also causes some surging while warming up--feels like someone has tapped the truck from behind. Also, if the ICE hasn't been running and up to temp, there can be a hesitation from a stop, from when you stab the throttle and the ICE shows up for work.

Anyone with a 23’ that was built toward the end of the production for the year, having the shudder on decel when it goes from ice to electric? I believe mine was built late August 23’. I saw a Tsb, but it seems it was for the earlierbuilds

Yes I too have 23 xlt mavrick that was built 10/23.I experience, the same shutter as described in your article at low speeds when you come to a stop it feels like you’re putting in and out a clutch and once in a while, I experience the shutter like the vehicle feels like it’s being hit from behind. I’vehad it to the dealership number is times the first time they told me they couldn’t find anything wrong with it. The second time they experienced a small shutter and reprogrammed the transmission to no avail. The vehicle now has 39,000 miles on it and was still experiencing the same shutter when I took it to the original dealership I bought it from about an hour away. They told me they lots of experience with this particular shutter and told me they found a bad hub bearing and a bad CV axle. Well, it’s been over a week and no shutter experience anymore hopingthat was the problem. Hope this can help someone ,they said that they got a bunch of bad CV axles at the factory.
