Mine was a corroded wire they found running in the rear bumper... They had to splice in a new section.
I didn't get to see what it looked like... If there was a defect that caused it, or wear through the plastic coating... But it wasn't a software issue..
I think mine started driving through some crappy winter conditions too... Which is why I thought it was just covered sensors...
Im booked in a couple days, I'll update what they find/ do...
@Heliian in th morning, yes, from in the garage (but I've had the truck for over a year without that issue) but after work it's outside in a parking lot.
I've been getting this warning every start for several days. Initially thought it was because the sensors were dirty, but after a good wash and wipe and a couple of ignition cycles, the alert still pops up.
Anyone else encounter this?
Easy fix?
