2026 1500 5.7 start stop issue

[Jackljr77]

Does anyone else hear a pop from their rear when taking off after the strat/stop is engaged ? Sounds like a bang.

That's not normal. Take it in and have it looked at.

I test drove a new 5.7 a few weeks ago. I also noticed a noise coming from the back of the truck every time the engine restarted from a stop. I turned off the stop/start and the noise quit. Just another issue being cause by the despised eTorque system.
When I test drove a Hurricane, the rear end noise was not there, even with stop/start enabled.

It sound almost like a low key backfire or mini cold start

What I heard was more of a snapping noise, like something letting go of another part.

I owned a 2020 Laramie with etorque and a 2021 Limited also with etorque. Neither of those trucks did this. My daughter's 2019 Rebel with etorque did not do it either.

It’s a little exhaust pop or backfire when motor starts back up. That’s totally normal for the GT exhaust which I understand all 2026 Hemi’s have now. Mine has done that since new in 2022. I normally have the start/stop disabled but the pop is there every single time when I forget.

That's good information. None of the trucks I mentioned had the GT exhaust. Just another reason to disable stop/start IMHO.

Exactly I actually enjoy the pop and stop start engaged will actually help with the lack of lubrication these engines experience at idle.

Yep! This. I thought something was wrong and rolled the window down. Realized it’s the snarly GT exhaust just doin what it do. All is well.
