Water entered tailgate through drainage hole in tailgate cap. The water then dripped on the tailgate switch causing it to short out. This short circuit caused my tailgate to open and close randomly without pressing any switches or buttons or key fobs. May tailgate has a small ding it it now from where it kept hitting the wall while parked in the garage. I took the truck to the dealership to get repairs done and was charged 308.88 for the tailgate switch and diagnosis that should have been under a recall for this truck. Safety Recall N232426400 Tailgate May Open Unexpectedly issued May 2024. I called the customer service number [XXX] to try and get reimbursed for the repairs and they told me there is no recall on my truck. I had this problem and it clearly states the year, make and model of my truck in the recall, but because my vin wasn't included I'm out of luck? I will attach all the info i have on this matter. Any help would be greatly appreciated. Thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Is 40 complaints a lot? They were filed between 2020 and 2026, roughly 7 a year, which is fewer than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2021 has 40 complaints on file, more than the 2020 (28) and more than the 2022 (27). Of the 15 model years of the Chevrolet Silverado 3500 we cover, the 2015 has the most (52). Older model years have had longer to collect complaints.
