Maybe instead of plastic they need to make it from a more pliable vinyl material.
These aren't pick ups with frames so it is unlikley body twist. Hoisting problems, maybe. Anyone have an old one to see if there is a "water pocket" behind the trim for water to collect and freeze?
I don't think it is a water freezing issue, although it could be poor Quality Control allowing mis-sized rockers to be put on the cars.
Also, there are cars in the south that don't experience any water freezing situations that have cracked rockers.
Sadly, my car is currently sitting outside (daily driver) and not under any car cover/carport or any protection (yeah, I know). We get 4 seasons here - heat and snow and rain and slush and wind, etc... I'm currently under snow.
Car is roughly 1 year old.
I have not had any cracked rocker panel problems.
Although I have always told anyone who services that car that the rockers have been known to crack if not properly lifted and I keep a copy of the lift points sheet in the glove compartment and give it to them telling them that there are no cracks on the car now, as I drop it off.
So far, so good.
I think it is mis-sized rockers - the QC tolerance is not tight enough, or damage caused by lifting or some other situation.
