Words owners used for the same problem are counted together, so a fault written four different ways is measured once. Grouped by which complaints they appear in, not by a list anyone wrote in advance.
What owners wrote
First incident we were driving on the interstate towing a fifth wheel RV, and several warning lights illuminated before everything just shut down. Manage to get to the side of the road. Vehicle finally restarted and the rest of the trip was uneventful. Second…
Rear wheel lockup event in traffic while towing 24000lb 5th wheel on freeway. Vehicle was limped to a dealer, diagnosed as a transmission valve body failure. Repair took over 1 month stranding us over 1500 from home while on a trip.

How this was worked out
Every year of the GMC Sierra 1500 was compared against its own history rather than against other cars, which removes popularity and age from the answer — a common car draws more complaints at equal reliability, and an older one has had longer to accumulate them. A year is flagged when it drew at least 2.5× this model's median and at least 50 complaints.
This is a fault record, not a review. Nobody files a federal complaint to say the car was fine, so it shows what tends to go wrong — not whether owners liked it, and not whether it is a good car.
