2022 ZR2 Colorado downshift issue

[Dan Hoenke]

When light-normal brake pressure is applied the truck lunges/lurches when approaching a complete stop, feels like a very hard downshift back to 1st.  it doesn’t happen if braking from speeds between 5-25mph, only if I’m going 30+ and approaching a red light/stop sign and am almost completely stopped.  It lunges so hard that the first time it happened I thought someone rear ended me.  Not sure if this is part of a normal engine break in period.

Bring it back to the dealer and let them sort it out. GM either F'ed something up, or still doesn't give a crap about their customers so some bandaid is needed to smooth out the wrinkles in some low-bidder junk parts.

 

Same crap I went through nearly 15 years ago with my toilet. I had to grease the splines on the transmission / transfer case yoke. Now I hear that burns up clutches on the newer ones, so the fix was a nickel plated yoke. Like I said - their problem, not yours on something this new.

 

The more things change, the more they stay the same ...
