Cruise Control problems of the 2016 Jeep Patriot

Bought Jeep in 2018 since then it has had intermittent cruise control problems. Sometimes it works sometimes it dont. Sometimes it works then quits working. Drivers seat belt will be buckled and come unbuckled have to rebuckle intermittently. Burning smell intermittently dont know if its oil, coolant or what was supposed to be fixed by Jeep who said it was leaky coolant still occurs. All of this has occurred while on the road.

Shifts from d to 1st on its own: from a stop, the 2016 Jeep Patriot semi-automatic transmission drops to first gear on its own. There is no indication until the driver has pulled into traffic and has no acceleration power. The dash light indicates the vehicle is in 1st gear, but the driver was not expecting this and must either gun the engine and take rpms off the chart to avoid a crash from oncoming vehicles, or manually shift the vehicle to n or p and then return to d for a type of "reset". The issue is intermittant. The dealership where we bought the vehicle cannot replicate the problem (in to shop 3x for this issue). They replaced the stick sensor and opened two separate staron packs with Jeep engineers. But the problem continues. I suspect its transmission ($$) related or electrical ($$). Moving on to new dealership service. Fingers crossed. Cruise control: when cruise engaged at 70-75 mph on open hwy, had to slow for traffic. Speed dropped down to about 60-65. When reengaged cruise, the vehicle accelerated uncontrollably--rpms shot through the roof. Had to tap the breaks to disengage cruise and whole family experienced a hard lurch. Reported issue to Jeep service as perhaps related to issue with downshifting to first. Response was that this was normal. Seatbelts: when a person weighing more than 230lbs sits in the front seats, the seat belt warning sound dings as if the belt is not engaged. The dealership replaced sensors in both front seats. Problem resolved.

I bought my 2016 Jeep Patriot new. It has 20,000 miles. The abs and traction control light is on. Cruise control stopped working. Windshield wipers make popping noise when on. When at a stop the engine makes a rattling sound. When acceleration it makes a weird noise and takes forever to get it to the speed of 60mph. I can't get my car in for repair until June 14, 2016. Everything that went wrong happened at the same time except the windshield wipers. I smell a lemon in the bunch here!!!.
