Wheel Well Liners Promotes Rust??
Big R ED posted a topic in 2014 - 2019 Silverado & SierraHas anyone ever removed their liners and inspected the wells' steel several years after being installed? My concern is, since the liner is not chemically bonded to the steel (eg undercoated, bed-coated, etc), there could be pockets of moisture trapped between the backside of the liner and the well steel, that never really evaporates. I would think this collected moisture could pose a real problem, especially at weld points. I understand that the liners themselves will protect the surface of the factory painted wells from being compromised from stones, etc., but what about small pinholes or shallow coatings that might exist in the factory paint (especially at welds). My '19 LD came with front liners, and I'm looking for some feedback for my rears.
This post was about preventing rust on fenders. I did not get much response so will be reposting in another thread.
I purchased a brand new 2019 2500HD LTZ Iridescent Pearl, 2 weeks ago here in Oklahoma. The truck had 26 miles on the odometer. 3 days after I brought it home, I gave it its first washing. I was so proud of this brand new truck until I ran into rust, on the lower part of the doors. I thought to myself I just purchased a brand new truck for $60,000, why in the world am I seeing rust. I immediately crawled under the truck to find multiple components that have significant/moderate red rust showing. The trans pan and rear disc brake covers are losing their plating with rust coming through. I immediately contacted the salesman asking to bring the truck back and trade for a different one, but......I was told financing already went through and they could not take it back. That was 3 days of ownership. It's been very painful and disappointing to this point, but I did get the truck into the Service Manager and he took pics and trying to see what GM is willing to do. I just came back to Chevrolet after years of Purchasing Ford products. I even have my 1949 5 Window that I drove in college. Has anybody seen this before on brand new GM trucks? See Pics
I just purchased a new GMC 2500HD at Allen GMC in Orange County Ca. A week after delivery I discovered the entire underbody of the truck was covered with dried Road Salt. I did not inspect the underbody prior to purchase because I didn't think I had to. To make things worse GM is well aware of the issue. In April 2018 GM issued Bulletin PI0281G (attached) to Dealers. So GMC builds this beautiful truck, then they take it out in to a storm on roads covered with a corrosive chemical (road salt). They don't bother to wash it off they just ship it out to a Dealer. In my case California. You should know as the temperature increases so does the rate of corrosion. Having grown up in the "salt belt" Wisconsin I know the extreme damage done to vehicles by Road Salt. So GMC in an effort to cover their tracks notifies Dealers of the issue and instead of a discount or compensating customers they just say "that's the way it is. No consideration for damage will be made other than normal warranty coverage" . To me there is something very wrong with being aware of major corrosion damage to a vehicle and not disclosing that fact to the buyer! It would be different if they delivered a new vehicle to me and I covered it in salt, but, I didn't get the chance to even get it over the curb the damage was done pre-delivery. I pursued a vehicle replacement through the dealer and GM Customer Assistance but GM is refusing to replace the vehicle. Buyer Beware! Inspect the underbody of your vehicle before purchasing! I will post an update when I have it but the bottom line is I'm not getting stuck with this corroded junker. I bought a new truck and I expect to get one. PI0281G Underbody Corrosion.pdf
The bed corners (getting thin) and the rear leaf shackles (lots of pack out) in particular may be a problem soon. But it's an awful pain in the butt to crawl around under there trying head off rust at the pass. How much longer do you think this truck's got before I have to worry about something giving out at max payload?
Clear coat on Alloy rims
FarmKid92 posted a topic in 2014-2018 Silverado & Sierra TroubleshootingWhy do GM aluminum alloy rims all eventually go to s***? 2015 Sierra, rims saw two winters before I bought snows on steel wheels... I mean, I'm guessing it's from salt getting under the clear coat, but why? Been an issue forever, Dad's 04 Silvy did the same and now the whole rim looks like hell.
