jeep wrangler 4xe engine problem

[Felix]

Hello everyone! I have a 2024 4xe jeep wrangler but I feel that the electric engine is limited, because when accelerating slowly I don't feel any problem but when I accelerate quickly the electric motor makes a strange noise around 30 mph and accelerates slowly but after a few seconds the sound disappears and my jeep picks up mph normally. Does that happen to you with your 4xe?

Normal. There's a vibration/buzz in the driveline at the top of second gear in full electric, happens in all of them.

thank you so much for your explanation. I was worried about that sound.
Any tips for taking care of my 4xe? I've only had my Jeep Wrangler for four months and I'm in love.

Follow the factory maintenance schedule and enjoy it! They’re great vehicles. Congrats!

The problem is not normal. I finally solved the problem with a PCM and TCM update. If anyone has the same problem, tell the dealer to update the software.

Oh wow, I’m gonna have to go back to the dealer and have them take another look. Thanks for updating the thread!

Yeah, I was just going to say that my 4 month old 4xe does not do this.

Honestly these things get batches of flash updates every few months. Worthwhile to just have the dealer double check everything is up to date when you have the oil change done. I've seen some grand cherokees come in with 15+ flash updates available before. Lots and lots of software bugs they're fixing after release these days.
