Vehicle Shudder problems of the 2017 Jeep Cherokee

While driving the service shifter lighter appears on dash and shifter position lights all light randomly and has been becoming more frequent. They turn off once I stop, turn the car off, and restart the car. I have read models previously have been recalled for this issue but not 2017 which appears to have the same issues. Also I've had to change my spark plugs at about every 50,000 miles. I replaced them once already and once again I am having the same issue the check engine light is on and at times the car is shaking from the misfiring. The check engine light remains on at a times. The check engine light flashes and the car is shaking the power and acceleration are significantly reduced when the spark plugs are actively misfiring. This only occurs with accelerating and pressing on gas pedal and happens constantly while driving. I've never had to replace spark plugs this often they usually last atleast 100,000 miles. There is a problem when they barely last for half that and require replacement atleast 2 times before they should go bad. These seem to be a common issue but when you ask the dealer they act clueless and something needs to be done. These are costly problems that should not be occurring or occurring this frequently. Please investigate.

For over a month now ive received"service shifter" message. Car shakes badly and loses power as if its going to shut off. Three different times it did shut off and struggled to re-crank! service shifter message goes away after turning the Jeep off & back on. Very unsafe when driving on the highway (or anywhere)!!! purchased brand new and is up to date on oil changes, etc. Jeep also burns more oil than it should.

Car revs up like it shifted into neutral while traveling 65 mph, loss of power, no acceleration. I was on highway and was able to make the shoulder safely. Several error messages popped up on the screen, place into park and restart, etc. . Did not catch them all. Put into park, shut off and restarted. Regained power but the car stutters and shakes at about 25 mph, seems like it is missing out while idling. This has occurred several times the past month. At first turning the car off and restart would run fine for several days. Until yesterday, now it is stuttering while driving on local streets. The service four wheel drive is on. The service engine light comes while driving but does not stay on once put into park.
