Zane Merva Executive Editor / Publisher, GM-Trucks.com April 12th, 2019 A few months ago we started to notice something on our 2019 Silverado that no owner of a brand new vehicle wants to see. Rust. Specifically on our rear bumper, just around the plastic step. It wasn't huge and didn't spread very far from the edge... but we couldn't stop noticing it. There was no excuse for rust on a 8 month old vehicle with less than 10,000 miles. The photo above shows the minimal but noticeable rust patch. It was even happening on both sides and in the same place. The issue seemed odd. Unfortunately, we've just been too busy to bring it by to our local dealership for them to look at. Lucky for us, our procrastination has paid off, because in the time between us first noticing the problem and getting off our lazy asses to drive to our dealer, GM has released a TSB about this very issue. It appears that on most of the early trucks, production of the bumper was completed incorrectly. The steel assemblies should be bent into shape then chrome plated. But that didn't happen in a small part of the early bumpers. The supplier bent the area around the side step after the bumper was chromed. The new folds in the steel damaged the chrome, cracking it and making the truck susceptible to rusting. What's the fix? If your bumper is rusting already, Chevy and GMC will replace it. If it has not yet started to rust, they will apply an automotive grade wax/sealant to prevent rust in the future. If you're unsure if your 2019 has this issue we suggest doing the following: 1. Give your truck a bath for heavens sake! 2. Clean the rear bumper step area with a hose or pressure washer. Front and back! We find lots of dirt collects behind our step in the bumper assembly. 3. Inspect around the foot step area and behind the foot step area. We found rust in both areas! 4. If in doubt, wait for it to rust and kindly ask for a new rear bumper. Our dealership, Banks Chevrolet in Concord, NH has been great getting our rust issue fixed. Our service adviser Justin has kept us in the loop during the repair and gave us a loaner Silverado LT while they have our truck. He even made sure any other outstanding service updates are also applied to our LTZ while it was in the shop. As it turned out, there were six open issues that needed addressed. Here's the official Service Update you can print out and bring to your dealer when you take your Silverado or Sierra in for service.

New to the this forum but a seasoned vet on others. I’m posting to see if anyone else is having brake issues after the TSB for the brakes on the 3500 L5P. If not to keep an eye out. Long story short, we just finished a 12 day camping trip up the coast of California. On the last day we headed home which is 4 hours away pulling our 5th wheel. (2023 Momentum 395M). 30 minutes from home, We were getting on the interchange and noticed some clear white smoke corresponding with my break pumps. On the third pump I lower my trailer breaks thinking it was set too high cause of the steep grades. Pumped again and that’s when I got a steady white smoke. Pulled over right away and inspected to find fluid leaking in front of the driver rear tire and a small fire. First thing I do is shut off the truck. Run around and get my wife out of the truck so we can kids and dogs out. As I turn around my 4 year is strapped in his car seat with flames all up the rear door and back glass. It happened so slow and fast at the same time. All I could think about is that glass breaking and the oxygen sucking the flames in and watching my son burn to death in front of my eyes and I can’t do a damn thing. I did indeed get him out and the family in to the trailer. We were stuck in what I call the kill box now. It’s 2 major freeways that interchange in to a 2 lane highway with at least 1/4 of concrete barrier on both sides with no turn outs not too much further up. We were lucky to stop where we where. We tried to put out the fire out with 4 extinguishers between the truck driver, tow truck driver and myself with no anvil. At this point I have to either get my family out of the trailer or unhook and try to drive off. Well ….. we were able to unhook. Jumped in the truck knowing turning on the fuel pump was a terrible idea. The thought of my family sitting on the upper deck on top of 2 propane bombs under them just gave me the push I needed to commit. Turned her on and floored it. The truck had exploded with me in it. I still remember seeing the flames all around, the heat and smoke in the cab. I was able to exit the vehicle after that excess fuel to burn off. I suspect that the initial fire started on the passenger rear and moved to the driver rear. As there are tire stamps from the right rear some something hot, melting or leaking for over 80 feet. Where I stopped first. You could see that it was leaking where the tires would be. Puddle is wet on the right side and the left is burned. if fuel was leaking, there would be a fuel burn line or fire. This is what I think happened but we will have to wait and see what the experts say. We are very fortunate that there were no injury or fatalities. Insurance company has taken custody of the truck and investigation is pending. I only have 17k left on the loan and had 15k of parts and labor in to it. Mods were as follows. 35x12.5 wrapped on 20” Fuel Triton wheel, K&N drop in filter, S&B 62 gallon fuel tank, Retrax hard roll up bed cover, B&W 5th wheel hitch and custom mudflaps. All I know is that I almost lost my family, trailer and truck that I’m most likely going to lose on. 3500 was purchased certified used last June around 14,000 miles and burned down last Thursday with about 16k on it. Now the adrenaline and shock has worn off. The anger and ptsd is kicking in. We wouldn’t have gotten out with our skin suits with out the help of the kings if all kings …God, the 2 Good Samaritan and our great first responders. In the end of the day I have my family and health and thankful for that. I’ll be posting my outcome, as soon as I hear back and case is closed.

Hello all. This is my first post on this forum. I joined just a few days ago and have been searching this forum for my answer but cannot find it. I tried to use the search feature but it doesn’t seem to work on my iphone. I have been having problems with the infotainment system with my truck that i bought about a month ago. Its doing the thing were it will play bluetoothed music the same time as the radio. From what i have read is that there is a software update available that resolves the issue. My truck also has the “Advanced Trailering Package” and some of its features have been a little glitchy so i plan to take the truck to the dealer to have these updates done. But before i go i want to be ready with specific TSB numbers so they know i mean business and dont pass them off as normal. I would also just like to know in general were i can find a continually updating list of TSBs for our trucks. Can someone please point me in that direction? Thanks! -
All, I have a 2015 Suburban LT with just over 40k miles, with a couple of issues - all of which have TSBs. The steering wheel pops when turning. I have been told that to fix this issue will require the replacement of the steering column; the driver seat is literally a pain in my rear. From reading other forum posts, I believe this is probably a seat sensor; and the driver seat rocks/pops/moves when I turn. The Chevy service department I visited said that I had two options: Pay big dollars to fix it, or live with it. At this point I am really regretting my purchase. It seems to me that for a vehicle that costs nearly $70k new, one should be able to expect more. Now, I am wishing that I hadn't moved on from my 2005 Suburban. I would appreciate advice on working my way through a customer service complaint, and how to get this issue resolved. Thank you!
