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…

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.

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.
