2024 Trialmaster, 2" lift, 34" tires, Comeup winch and install kit from OK4WD. Have been experiencing cruise control issue, to wit: After a variable amount of time on cruise control, speed will abruptly decrease by several MPH, then possibly (or not) spontaneously increase back to the set speed. This is independent of whether I am following another vehicle...tho the cruise does appropriately slow when getting too close to the preceding vehicle. If I cancel cruise for a few minutes then re-engage, it generally behaves normally for another random period before exhibiting the same behavior. Have had the dealer (Lyle Pearson, Boise) check it twice. It is not throwing codes, and on brief test drives they have been unable to replicate the behavior.
Did the above mods soon after I took delivery of the vehicle, so didn't really experience much highway travel prior to the mods. Can't say with certainty whether the issue existed prior to the mods.
The radar sensors are clear. I have a Winnebago Revel (Sprinter) that has cruise control issues when it gets bugs on the radar sensors, so I always check.


Anyone else having similar issues?
