2018GMC

Thanks for the detailed reply. Crazy what issues can creep up with a weak battery on these trucks.

I don’t miss my 2018 K2xx because I still own it! It’s paid off, the hard to find (in my area) crew cab standard bed max tow 4wd 6.2 with Denali cluster. The late build K2xx options like Automatic HID headlights, automatic low speed braking and lane keep assist. 1900lb payload and 11,700lb tow rating is way more than enough for me currently. Tows my 4klb enclosed trailer with UTV like it’s barely there. Only has 12k miles. Been pretty much problem free. Bumper to bumper warranty is up March 2021. I plan on keeping it unless it gives me major problems or the next redesign is amazing or has something I can’t live (want) without. When GM finally adds Super cruise and an interior redesign it *may* entice me to trade in. Definitely something to be said about a paid off problem free truck.

I’m not excited to replace mine when the time comes. I will prob go for a Walmart / sams AGM. Maybe north star if I feel like spending that much. Has optima improved since the mid 2000’s? I know when they moved production out of the USA people complained the batteries weren’t as good and didn’t last as long. What model and brand of replacement battery did you install? Any odd behavior with dying battery or it just wouldn’t start?

6-speed or 8-speed? If it is the 8-speed a fluid exchange may help as the factory fill fluid is hydroscopic and slowly absorbs water which will cause torque converter issues.

My 2018 has a piece of dirt or flake in the paint but it’s where the anti chip paint is on rocker panel. I can live with that vs taking it in and hope they don’t overspray my door or scratch good paint. One thing I don’t like on K2xx and t1xx is the new door design with the rocker exposed. You now see the rocker where people drug their foot getting in and out which makes minor scuffs and scratches. The older design had the door cover this area so you only see it when doors open. 3M clear bra won’t stick to the anti chip paint. I constantly remind my family to not step on the paint! the the plastic door sill and then the ground.

See if dealer will repaint. If they won’t fix to your satisfaction contact GM and that should get the ball rolling. I hate going to the dealer for issues as well, not impressed with my dealers at all but if you can’t live with it then definitely take it in while you have bumper to bumper warranty. once 3yr 36k miles is up your living with it.

Bilstein 5100 will raise front 2” and gives you an extra 1” of front end travel. No need to change any components, uses stock spring, control arms etc. Take a look at fox and king for larger lifts. Bilstein 6112 is a larger diameter shock with new coil spring. https://www.shocksurplus.com/pages/bilstein-6112-vs-fox-2-0-performance-coilovers-the-need-to-know

$700 with 800 miles on 265/65/18 Goodyear fortitude HT. Thought that was a great deal since the tires alone cost that. They are not aggressive off road but I wanted a summer set of tires and these supposedly do ok in some snow. All season. I have a set of 33” BFG ko2 on 17” wheels when I want off road look / winter. People asking $1300 - $1500 for AT4 takeoffs with Goodyear DuraTrac tires.

Looks good. I got oem AT4 18” wheels and tires off Craig’s.

I have sunroof on previous gen K2xx. No issues. Got it tinted with dark tint and leave it closed but shade open all the time. Gives the cabin a more open and brightens it up a bit. I have heard of sharkfin antenna leaking and rear windows leaking but not sunroofs. Have a 92 accord with sunroof, no issues still works great. Friend has an 03 suburban with sunroof. No issues.

Yes on stability although a few more inches in wheelbase you prob won’t notice. Payload is slightly less because the truck weighs more vs short bed. I like the look and function of the longer bed. Can fit a dirt bike with tailgate closed, etc

^ This My 2018 SLT crew cab 6.2L 4wd 6'6" standard bed Max Tow package weighs 5700lbs and is rated at 11,800lbs. Doubt I would ever want to tow that much. I regularly tow a 7x14 enclosed that weighs in at 3500lbs loaded. That is no problem at all. I'd be comfortable towing up to 7500 - 8000lbs with sway control and weight distribution hitch.

I occasionally see service stabilitrak after starting. Once in awhile get a service safety restraint system. 3/36 warranty is up March 2021. Local GMC dealer just shut its doors...

Any updates? Did this get fixed?

Damn, that was a hit. Glad everyone walked away. What was the other driver in? Had to be well built since they walked away as well? Well wishes and be sure to post some pics of the replacement.

If this bothers you, don’t look at the Rear bottom corner of the crew cab doors. They stick out with a large gap by design. It’s also bothered me how the rain water just runs on part of the inner door plastic frame. To keep things in check, I just look at the gaps on my 1979 K10 and 1997 k1500. Wow, there isn’t a gap that matches on those generations. Now my 2018 looks amazing. GM has come a long way! I think they actually started caring about body panel gaps on the 2007.5 GMT900 generation and up. Before that it was “good enuf”. Cheers

That sucks. Shop around local body shops. Check their reviews. They shouldn’t have to paint the entire door. Just blend in the area that they paint. if you have the tricoat paint maybe it can’t be blended and that’s why they have to repaint entire door? Seems like dealer just being a dealer and asking the max price.

Here is my 2+ year review of Extang Solid fold 2.0

Amen

Specs in my signature 2018 GMC Sierra SLT Premium Plus crew cab 6.6’ standard bed 4x4 6.2L L86 max tow 12 bolt 9.76” 3.42 gears. AT4 18" Wheels 265/65/18" Goodyear Fortitude HT from K2XX. Denali Cluster, JL center console stealthbox 10" subwoofer. Sunroof. Bilstien 5100 front & rear. Extang Solid Fold 2.0

Yes it will fit as long as they are both 6.6 standard bed and not 5’8 short bed. 2500 and 3500 HD 6.6’ beds are same as 1500 in 2014 - 2018 K2xx generation.

I prefer to buy near end of model year. Seems they have at least some of the early issues worked out if not all. You also get all the added tech that wasn’t available during launch. My 2018 has been trouble free but only have 10k on it. I’d suggest you wait for the 2022 refresh. New front and rear clips and redesigned interior. Rumor is super cruise will be available as well. I’ve been watching the 2019 - 2021 models and there are some issues but nothing out of the ordinary for a new platform.
