2013 GMC SIERRA 1500 Complaints

Failure of frame on left side of vehicle between frame rail and fuel tank. For a approx 10 year old vehicle that is garaged and does not drive in inclement weather this SHOULD NOT be happening.

The contact owns a 2013 GMC Sierra 1500. The contact stated that while having the vehicle inspected, the vehicle failed inspection due to the rear subframe being detached from rust. The contact stated that the failure was related to Technical Service Bulletin: 19-NA-255. The contact used the undercarriage wash due to residing in a snow and salt State. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 75,000. The VIN was not available.

On 9-12-25 I was pulling a utility trailer when I went to back it in the driveway my 2013 gmc 1500 5.3 stalled . I restarted it only to have a lifter claddering !!!! I checked the oil it was good ! Oil pressure was good not over heating . It is just the lifter!!!!!! After doing some investigating I found that this is a common problem with GM's 5.3 with the AFM system!!! Companies should be held accountable for fraudulent designs!!! This is Not the first time for GM screwing consumers!!! GM had a similar situation back in the 70s and 80s Cadillac!!!! I bought this truck from a GM Dealer with 67000 miles only drove it in 1 winter it now has 149900 miles!!!! 5 years !!! Change oil and filter every 3000-4000 miles ,use Mobile 5w- 30w !!!! I feel a recall should be made to hold GM Accountable for what they new was a problem but produced and Screwed consumers to make SALES !!!!!!!!!!!!! Ask any quality Repair facility that works on GM'S or Even Auto Parts personal. When it stalled it left me in the middle of the Road with traffic!!! Even if it did start right back up !! Clacking!! The cost is unbearable!!!!!!

DURING AN OIL CHANGE IN MAY I WAS INFORMED THAT MY FRAME WAS EXTREMELY ROTTED AND WAS IN JEOPARDY OF CRACKING IN HALF . THE FURTHER I DIG INTO THIS, I'M FINDING THAT GM IS AWARE OF THIS ISSUE. THE VEHICLE IS AVAILABLE FOR INSPECTION.

Roof rust at the windshield on a perfect condition vehicle. Paint is excellent on rest of vehicle. No damage or accidents and properly maintained. Premature rust is now visible at the roof of the of the vehicle. Soon could rot and allow water into cab of vehicle.

The frame on my 2013 GMC Sierra has a considerable amount of rust & corrosion on it, to the point of being a safety concern because it's actually rusted through to where there are holes rusted through the frame!!

I found out that the frame was rusted through beside the gas tank and was told there was a memo put out to the dealers that there was a problem with the frames not being coated properly and if the customer notice it they were to repair it. My truck was service regularly and undercoated regularly by the dealer the body is rust free but I am being told the frame is on safe and can't be repaired and GM will not make it right even though they knew there was a problem. I pull a travel trailer and if the frame was to break in half I am sure someone would be seriously hurt or killed.

I hit a bump and both rear shock mounts blew off the rear cross member because the frame is rusted out despite having rust protection. It is available for inspection. The truck then began bouncing wildly. Meanwhile the underside of the bed isn't rusted at all, not one speck. It just seems weird to me, reminds me of the Toyota frame problems from a while back. It has not been inspected by a mechanic or insurance, my insurance company didn't seem to care in the slightest. I have had traction control and abs warnings on for a while but my mechanic said that was a faulty tire sensor.

Frame rust on left rail at fuel tank . The truck was a 47 thousand dollar truck bought new 1 owner 11 years old frame has holes when is gm going to be held accountable. Toyota had frame recalls for this same issue .25 year + gm owner can't see me buying another gm product

Rear half of Frame Crossmembers rotted away between the Frame rails. Took vehicle in for routine safety inspection, and the mechanic determined that the cross members to which the rear shocks and the Gas tank were attached had both broken free from the frame rails due to rust. The entire back end of the vehicle is suspended from the frame with only the leaf spring mounts. This rust is excessive and far exceeds the rust on other points on the frame and undercarriage of the vehicle.
