First Time Truck

Picked the truck up yesterday, service manager said they repositioned ground wires. There were multiple codes - P2122, C2a07, u0131, u0151, u0102, u0140, and u0146, they inspected the engine compartment wiring harness for rub through and connector terminal contact per doc 5568637, repositioned harness and secured per doc. They test drive multiple times and codes did not reset. the drive home from dealership was uneventful as everything seemed to work fine.

Thanks for the update, I am in a similar situation. 350 or so miles in truck. Got a service transmission, service ESC, traction control, CEL. Dealership called and said maybe an electrical issue. Been there about a week and a half.

Hi OP, any updates regarding the issue?

Hello all, I’m a little confused as I just dropped my 2020 Sierra with 280 miles off at the dealership. Received a check engine light and notice to service ESC, engine loosing power warning. I know about the 8 speed shudder/ shift problems however I thought dealerships fixed this issue with a tranny flush and new fluid. Has anyone else with a new 20 model experienced this? Thanks For your responses in advance.

Thanks for the help!

Thanks for the response, however I was hoping to get information on the silver trim ring around the fog lights. The higher trims have inserts in the bumper cover that the trim ring attaches to. Is there any info on the bumper recovers being universal to all 1500 models?

Hello everyone, I am new to the Sierra family, just picked up a 20 Sierra SLE 1500 and enjoying the truck so far. Looking forward to learning from everyone here on the forum. I have a few mods in mind but want to start with fog light installation. I noticed the higher end trims have a different bumper cover with a different part number that allows for the trim bezel piece insert, does anyone know if these parts are interchangeable, the SLE does not come with fog lights or the bezel/clip and I want to add this to the look of my truck, if I were to obtain the SLT, Denali, or AT4 bumper cover would it fit on my truck that way I can have the fog light trim bezel? Thanks in advance,
