Constant smell of coolant while stopped at traffic lights or idling even worse when the air vents are on, dealership insists it's because the reservoir cap is vented but coolant reservoir is literally a foot away from drivers window even still shouldn't be smelling coolant it's been like this since a month after purchase. Having issues now with auto braking system activating for no reason did this multiple times almost got rear ended on NY State thruway because it activated with no cars near me once it activates it causes the truck to go into a limp mode (won't go over 30 mph) and starts vibrating like it needs a tune up. The radio and digital display often dissappear for no reason can tell speed. I almost got a ticket from state trooper for unsafe stopping i explained everything and was told i could get a safety violation for defective equipment and to take it garage and drive it till its fuxed , the windows have rolled down a couple of times while it's parked and won't go back up. Headlights often flicker when driving auto low beam/high beam rarely works. Every time it goes to dealership they say they can't duplicate the problem. It's really scary when you're doing 70mph and the auto brake engages. I'm literally afraid to drive it. I have a 14 year old truck with 230,000 miles I don't smell coolant or have these kinds of issues Seems to be a lot of electrical problems going on service advisor said he saw notices for bcm, front facing camera total of 6 issues. Nothing seems to resolve issues but dealerships aren't doing anything just saying can't duplicate problem also paint is chipping every where The issues started around 5300 miles and continuing

The screen in the Truck doubles in picture, freezes and/or shuts down completely. This leaves you with out control of your GPS, radio, blue tooth, head light control and backup camera. Research on the internet has proven this seems to be an accruing problem in this truck, with some even losing their speed information. So far it has resolved itself after a while on its own, thankfully, but each time it happens the black out is lasting longer. In order for the dealership to recognize this problem we must drive to them when its occurring, which hasn't been possible. Owning this truck for 2 months and the issue of losing the computer system has occurred 4 times, this vehicle is not a daily driver.

While driving to work today in fog, the vehicle auto headlights sensed enough light and turned off. Because it was foggy outside I did not feel safe only driving with DRLs on so I attempted to turn on the headlights using the touchscreen controls. The headlights would not turn on. I have video evidence of the headlights not responding to the touch controls and remaining off despite trying to turn them on.
