POWER TRAIN
The vehicle jerks when I put it in reverse or drive. And when I'm going down the road while it shifts gears. It's be doing it since I purchased it (new). It was light at first but lately its been worse. I took it to the dealership a couple of months ago & they replaced something small & said it was fixed. But it still bad. My truck still only has 30K miles.

SERVICE BRAKES, ELECTRICAL SYSTEM
Last Weekend was taking the kids and my brother and his son fishing, so 2 adults in front seats 3 kids on the backseat. Got my boat all hooked up and we're off. About 2 miles down the road the truck rebs up really high and then bottoms down hard on the RPM's. As soon as this happens all lights and instrument cluster goes crazy. Check Engine light on, Parking Brake Light On,Traction Control Light On, And I'm sure I'm forgetting more. The Cluster states ESC failure drive with caution, Do Not Exceed 43 miles per hour speed limit Brake Failure and So on. I have since found pictures pf the exact same thing that happened to me that morning and will provide. Needless to say I have no brakes and have a 19 ft bass boat behind me. All I could do was let off gas completely and push brake pedal all the way to the floor and pray that it stopped. Good Lord willing it did. Pulled over asap and killed truck, let sit a few minutes while I assessed the situation and cranked it back up. All lights and brakes were fine. Has not done it since but I only drove to dealership to find out the issue and 4 days later still no answer. Its a 2019 with only 26000 miles, and has never had 1 issue before this

EXTERIOR LIGHTING
The sockets in the rear brake lights had excessive corrosion and was causing the terminals on the bulbs to deteriorate. The lights were malfunctioning in all situations from braking, turn indicator and running lights. I was notified by the system that there was a problem. After trying to resolve the problem and replacing the bulbs the condition only worsened. I was then pulled over by law enforcement that told me I had nearly no rear lights at night. After banging the plastic light frames I was able to make it home. I brought my truck into the dealer who inspected and found faulty wiring from what I was told. I them paid to have both rear harness change and all the bulbs replaced to repair the condition. After review of the repair the dealer made no additional precautions to ensure that this condition would not return by placing any type of waterproofing dielectric grease in the sockets or connectors. So was this faulty wiring or simply a known defect. The dealer had them in stock which was surprising since I figure they would need to be ordered.

POWER TRAIN
when I bought the vehicle in October2018, I have taken the vehicle back to the dealership multiple occasions and they refuse to fix this issue. The transmission shifts from first to second gear or second to first gear is clunky, jerks forward and shifts without warning. While sitting at a stoplight, the vehicle will sometimes lurch forward several inches without warning even with your foot on the brake. Furthermore when accelerating between first and second year it's sluggish and takes several seconds to shift from first to second the engine Revs high.
