Hello everyone. My first time here. I have a 2021 Sierra AT4 with the 6.2L. I have started to notice a noise when towing our boat that weighs about 6,000lbs. Several times during the trip to and from the lake I hear a rumbling sound that last like 2-4 sec. almost sounds like it can be a jake brake or hitting rumble strips on road. I hit no strips. I can’t recall if it happens on downshift or what. But it does concern me. I drove home from work today with our towing and put it in tow haul mode. It made the noise 3 times in 45 min drive. Any ideas what I’m dealing with? Would it be a bad clutch issue or is this normal? I do have the performance GM installed exhaust and performance GM installed air intake. I called dealer today and they said bring it by and they MIGHT have time to get to it next week. I planned to hit the lake this weekend for Labor Day. Thanks.
I am wondering if anyone knows of metal skid plates available for the 2020/2021 Silverado 2500HD - and where to order them from.. URL, parts numbers, etc.
I am mainly looking for metal skid plates that cover the engine components at the front and one to cover the transfer case further back.
Bought this vehicle brand new. I love it, and perfect for myself, my family, and the fact it's Diesel puts the cherry on top for me. But... now things have started. We have currently 1,137 miles on the vehicle and had the first message populated:
- Service steering column lock. (see photo)
Everything else worked, remote start, standard start, and the vehicle had zero issues. The following day from our road trip, we had to go to the DMV with our out-of-state paperwork to submit for plates. My wife now received a new message.
- Service emissions system. See owners manual. (see photo)
She drove to the DMV and left to get the smog paperwork. Then a new issue:
- Vehicle remote start isn't working. (see photo)
She is in the car and tries to start... Nothing. She tries again. It starts, and she drives it to a local dealer. They come to look and scheduled us for an appointment. She drives the vehicle now, and Onstar now shows the emission issue. ( see photo ) We now can't register the vehicle in California, because, the check engine light is on, emissions warning, and they won't smog it until it's corrected.
I noticed that none of these issues happened until it updated the software in the vehicle. I'm hoping this is something that can be fixed. I've been looking around for answers and only finding more issues that are all pretty shitty. Sorry, no better way to say it. I've also seen a post of people saying, “deal with it, it's a new breed of vehicles,” etc. I’d challenge that answer. No one should pay this much for a vehicle and face these issues I'm reading about.
So here's what I'm going to do, document everything, and I mean everything. This will be for everyone who may have this issue now or who may come across it.
My opinion...but I'm not a mechanic, is that there is a massive software and hardware issue with these models. I believe GM internally has to know about this from Dealers, Customer Service, Compliance Reports, etc. I'm sure all issues are in the queue to be address or fixed. I do, however, feel with the challenges of physical hardware that they chose a vendor that was most cost-effective, which is a component of these issues a long with the capability to support the software complexity of the current models.
Or maybe I'm just wearing a tin hat, who knows.
So, I open this up to you. Any advice, similar issues, outcomes you've faced, and other topics, please comment below.
May the journey of dealership visits begin. Hopefully, this journey isn't to long.
