Chevy Silverado and GMC Sierra Rear Bumper Rust

any one else having a rust issue on the rear bumper right side by the tailpipe? i have had my rear bumper replaced once and 2 weeks later it was rusting again. now they won't replace it till spring cause they say its from the salt brine on the roads when i say its something from the exhaust since it only happens on the right side. seems funny huh since we all know salt only gets on the right side of the vehicle...

    Yea, I got rust on my 2008 Silverado bumper by the tail pipe. I've had the truck a couple months. I'm taking it in tomorrow for oil change, etc. and I'm going to see what they say about it. Hopefully they won't tell me I need to start using super premium gas. Maybe it's the guarunteed QT gas I use. We'll see.

    Hey, me too. I have an 07 Silverado bought in June of 07 and now I have small "blisters" of rust on the side of my right rear bumper. I have not reported this to my dealer yet. I will the next time I go in for an oil change. Unfortunatly, that side of the bumper looks like it has been hit by something and slightly pushed up on an angle. I noticed this aftter I saw the rust and think this may have occured in a parking lot although there is no sign of any mark on the bumper. I hope the dealer doesn't claim that the rust was caused by this damage.

    I'll let you know how I make out.

    I have an 07 Silverado Z71. Bought it in March 07. Love the truck. I have rust spots forming on the left rear bumper, drivers side not tail pipe side. Forming on the corner. Noticed it a couple weeks ago while washing it. I take good care of my truck and need to go see the dealer. I doubt this is an exaust issue. Sounds more like poor croming. I've been through one winter and kept the salt from the Mineesota roads off as much as possible. I won't except anything less than a new bumper. I too will keep you posted.

    If they're anything like my 2000 that rotted off 3 years ago, good luck at the dealer- plan on buying aftermarket. The dealer will be quick to SELL you one not telling you that it is an aftermarket. Get use to it. Sorry!

    Stopped at the dealership yesterday, no issues. They are ordering parts. Seems common as he knew what I was talking about and mentioned acid gases from the exaust. I have rust starting on both sides. Bumper is actually several pieces and he said it's a 4-6 hour job to replace the crome ends, nice design. I'm still under the 3 year or 36K mile warranty, lucky I guess.
  • ive not to date had chevy fix anything with my 2008 silverado. after 10 or so trips to the many dealerships and excuses now im over my 3-36000 warranty. truck runs great but after a battery which i went 3 times to address a problem, having to eat $171.00, front cowl noise that still isn't fixed, door air noise, a cheep pos rear bumper, excuse after excuse on everything i will never give chevy another penny of my money. o did i mention a front end alignment, less then the 20mpg listed, yea im not impressed with the bs chevy has given me. like i said it runs great but for the $$$$$$$$$$ i paid a new car should be able to be enjoyed not get bye with. anyone now where to get a nice rear bumper reasonable?

    Have a 2009 Silverado Crew Cab with chrome bumpers. Replaced front bumper impact bar at 816 miles now the back bumper is rusting. I have two friends that both have 2009 Silverado LT extended cabs three out of those four bumpers have been replaced within the first 5000 miles. Built like a rock. I DON'T THINK SO
  • I just purchased a 2009 Crew Cab and both of the rear chrome bumpers have rusted through and need to be replaced. I thought maybe GM had improved, now I know why they went bankrupt. I'm done with GM

    I have a small area starting to rust on my 06 around the licence plate lights. I'm not sure on how to prevent or slow down the problem. The problem today is everything is so cheaply built, everything is rush,rush. Any kind of quality seems long lost,

    It's hard to believe that chevy trucks built 30 years ago are still around, my last truck was a 96 GMC, 4.3 Vortec, auto, had 300k on it and ran like a clock.

    Back to the rust issue, i'm gonna try a Krown rust treatment, and see if that stops any more rust from appearing, with winter now only a few months away i have to try something.

    I have a 2010 Silverado with 5500km on it. Barely 3 months old.

    I have rust on the bumper already and the bowtie logo on the tailgate has rust forming. I have noticed other 2010 and 2011's with the same problem. Garbage.

    I just took my 2010 Silverado 1500 LT extended cab to the dealer yesterday with the same issues. The service manager wanted to just buff the bumper and replace the bowtie. Long story short, they ordered both bumper cap and the bowtie. seems the bowties are backordered because so many are junk. Good lick.

    Amazing this problem is still around. My 03 Sierra rear bumper literally started rusting the first month of ownership, similar to the above descriptions. First comment was, improper care. I said," do you guys prep your bumpers before a sale?".."well of course".."then you need some training, because your prepped this one 2 weeks ago!". Anyhow, they had to fight with GM for one year to get that rear bumper replaced. While picking it up, they admitted a bumper defect and my front bumper was also off being undercoated. Fast forward 7 years later. That replacement rear bumper still looks great. That front bumper is falling apart. Rusted from the back. So apparently GM still has this manufacturing defect, and a solution, but they can't seem to differentiate between the two. I get lot's of questions about those 2 bumpers from prospective truck buyers, it's like night and day and quite an experiment.

    wow. they know about this from that long ago? I had my 2010 right side bumper replaced just 4 months after getting the truck. Dealer said it was chines steel and chrome plating. I told them to send to local plater who does custom plating but no I had to get a new chinese replacement

    We have had the same issues on our 2009 silverado. GM's customer service was unwilling to work with us :-( so we sent a letter in hopes that they will admit that the parts are junk!!!.

    CASE # 71-xxxxxxxxxxx
    Code name “Rust Bucket”

    Dear Dan,

    I am writing to you in regards to a 2009 Chevy 1500 EXT LT that our family bought in the fall of 2009. In February of 2010 we noticed excessive rusting on the front and back bumpers and bowtie. When we took it to the dealer ship they told us to bring it back in the spring and they would replace the parts under warranty. So we came back in the spring and the dealership replaced the parts. Problem solved, right? Not so fast. Let us now fast-forward to December of 2010. We noticed excessive rusting on the front and back bumpers and bowtie. When we took it to the dealer ship they told us to bring it back in the spring and they would replace the parts under warranty “Déjà vu”. So we have now have had the front and back bumpers replaced twice and the bowties replaced twice do to rusting in less then two years. I called your customer service department to see If GM would warranty the parts that they have had to continually replaced. And to my surprise they unfortunately are unable to help me.

    This leads me to ask you this question. (Under normal conditions) “Do you think that it is a reasonable expectation that a $30,000 + GM vehicle could last more then a couple of months in the environment with out the bumpers and bowtie rusting out?” I have reviewed the forums online and have spoke with the employees in the dealership and this rusting issue is a known problem. One employee’s even told me they have been replacing the bumpers of the cars on the lots because they rust out before they even get them sold.

    What I would like from GM is a warranty on these parts for the next 3/yr or 36,000 miles. And I would appreciate it if it came from you. I would also like to hear what actions will be taken by GM to make sure that the issues with these parts are corrected. Please feel free to contact me at 585-xxx-xxxx
