I've got a higher mileage 2021 suburban (131k miles) and while it drives very smooth and has a controlled bounce over large smooth bumps, the fast sharp bumps like lines in the road or man hole covers really rattle the hell out of the vehicle, feels like the tires are at 80psi when this happens. I'm wondering at this mileage would all 4 struts fix or at least help this issue. These are non magnetic ride control, non air suspension.

I get zero responses in the suburban subreddit and the front suspension (to my knowledge) is pretty similar on the 1500 trucks. I get a metallic creak when I get in and out of the truck, I can also hear it inside when I'm driving over smaller bumps. It's not the sway bar bushings since it does it when I move the steering wheel side to side as well. Any help from you guys would be awesome.

I can't get my wireless charger to work in my 2021, checked the fuses, tried 3 different phones, took the cases off the phones and even removed the rubber mat on the charger itself with no luck. Do these typically go out and I just need a new one or am I missing something?

Just bought it 2 weeks ago, throws a code every other day for evap vent control circuit. I checked the vent filter behind the gas door and it was Packed with dirt, cleaned that out and still get the code. Did a systems test with my scan tool and both the vent solenoid and purge solenoid open and close upon command. Fuel tank pressure sensor reads 0.05- inH20 and 1.8 volts with key on engine off, I know it should be around 1.5 volts but those 0.3 volts wouldn't be grounds for a bad sensor I would think. The code only comes on in the morning after it's sat overnight, and not every morning either, just random. Just curious if anybody has had a similar experience. The car is originally out of South Dakota and saw a ton of dirt roads if that points anybody to some known issues.

Getting a P0446 vent control circuit malfunction and need to be pointed what to replace or have some insight into what someone else has done that's had the code. 2021 Silverado 5.3
