2018 CHEVROLET TRAVERSE Lane Departure Warning Problems

Hello this particular vehicle often gives us a message stating that side detection is temporarily unavailable and the main issue is the transmission seems to have severe shufdering issues and sometimes gives a shift to park message ive read others having this same issue being recalled but my vin is not listed! The car is available upon request for any inspections necessary

I purchased a 2018 Chevy Traverse with 6 miles on it. I keep my vehicle in mint condition and maintenance as needed and required. Recently in the past few months my car has been bucking when shifting gear engages in an automatic transmission. I took to dealership, and they stated it was the torque converter, and my vehicle has exactly 20,270 miles only. Not even passed the 36,000 marks but over 36 months. I bought an extended warranty thru Dealership which now sending someone to dealership to verify that this is infact a torque problem which were found 2017 and 2019 but not 2018 is hard to believe. They will be keeping it for 7 days and already had a recall for 2017 and 2019 so are they stating it only occurred in those years, and they fix the 2017 but then it skipped 2018 and jumped to 2019. Why...

When driving on a right hand curve with traffic in the opposite direction lane, the forward collision warning system flashed a large red warning flash on the instrument panel near the speedometer. This was alarming and caused me to put on the brakes immediately, although there was no impending crash. This cause the cars behind me to take evasive action and apply their brakes in an emergency fashion and almost cause several collisions.
