2022 ZR2. 54k miles. The Colorado has never run better (knock on wood). I don't know if it's because of all the maintenance I've kept up with or ATF flush or 3rd round of Valvoline Restore and Protect + Valvoline Restore and Protect Injector cleaner?? Runs like new. Shifting is even better now since the flush. Could also be summer fuel blend change over? Truck is definitely a tad more responsive.
Here are all the service and maintenance I've had done over 4.5 years:
Oil - every 5k (mostly AMSOIL Signature Series and now 3rd run of Valvoline Restore and Protect)
Differentials F/R - 20k (Mobil 1 75w90)
Transmission - 25k (pan drop/filter change (40% removed)
Transmission - 54k - full flush (100% of fluid removed/Mobil 1 ATF)
Air filter - 25k
Cabin Air filter - 25k
Fuel System Cleaner - every 10k (Chevron/Valvoline Restore and Protect)
Fuel - 93 (Top Tier)
Repairs:
Door handles replaced due to paint defect (warranty).
4wd actuator switch (5 min dealer fix/warranty)
thermostat sensor (warranty)
Likely Common Future repairs:
thermostat (a PITA to get to). Common failure.
shocks ($4k-$5k). Can last anywhere from 40k-120k. Mine seek OK at the moment. No leaks, firm.
The 22's got a torque converter upgrade (I think?). If I were to keep, I will have the $700 upgrade valve body put on. Solenoids sometimes fail but that seems to be related to longer oil changes.
Biggest complaints - interior rattles. Some days no rattles, some days a few. All the plastic looks cheap, yet the truck feels well built. Gen3 is a big improvement here. However, the plastic interior is easy to wipe down and keep clean.
