Cruise Control problems of the 2022 Nissan Frontier

Cruise control surging vehicle beyond initial set limit. I recently purchased my 2022 Nissan Frontier 4x4 crewcab from a texas dealership. After driving it for a week or so, I noticed that while the "cruise control" is engaged, any sort of incline ahead of the vehicle will cause the transmission to down shift and rev up the engine to 5k+ rpms which causes the vehicle to surge and speed up way above the set speed (cruise set to 45mph, the consequence is the vehicle will surge up to 60mph at times and then let the vehicle slow back down to the 45mph speed set in the original setting. ) I found that very unsafe and that my Nissan Frontier is not the only one that experiences this behavior. The internet has had a few reports/complaints on this very issue. According to some of these owners, there's a software update to address this issues. However, some dealerships will charge for this software update if your vehicle has gone past the 36k warranty date to the sum of $600 plus out of pocket. Meanwhile without that software update, the vehicle will surge unnecessarily and dangerously above the intended speed set initially. Respectfully, 2022 Nissan Frontier 4x4 crewcab.
