2017 JEEP GRAND CHEROKEE Wheels Problems

MY JEEP SHAKES DURING DIFFERENT SPEED LEVELS I CHANGED THE TIRE DIDN'T HELP I DID AN ALIGNMENT DIDN'T HELP THEY PUT IT ON THE MACHINE FOUND NOTHING WRONG WITH THE ENGINE NOTHING WRONG WITH THE RODE CV JOINT EVERYTHING LOOKS FINE NO ONE CAN TELL ME WHY MY JEEP IS SHAKING AND I CONCERN WHEN I'M DRIVING ESPECIALLY WITH MY KIDS

ON PARKING LOT ON REVERSE BRAKES COMPLETELY SHOT DOWN FILLS LAKE YOUR HIT ON OBJECT AND FILLS LOW DOWN HOW SAVE IS THIS?

THE MICHELIN TIRES-285X60XR18 NEEDED TO BE REPLACED AT 16,000 MILES. THE WEAR BARS WERE ALREADY SHOWING. I TOOK TO JEEP DEALERSHIP IN LANSING, MICHIGAN AND WAS ACCUSED OF DRIVING WRONG, NOT ROTATING AND BALANCING (I AM METICULOUS ABOUT SERVICE-SO YES, DID), DRIVING ON TOO MANY DIRT ROADS (LIVE IN THE CITY, CITY DRIVING ONLY-SO NO) AND OFFERED NO DISCOUNT ON NEW TIRES. DISCOUNT TIRE TOLD ME THAT JEEP IS NOTORIOUS ABOUT PUTTING ON CHEAP TIRES TO BRING DOWN COST OF CAR. SERIOUSLY 16,000 MILES OF CITY DRIVING! I BOUGHT THE CAR NEW WITH 30ISH MILES ON IT...THE TIRES SHOULD LAST MORE THAN 6 MONTHS. SOMETHING IS WRONG WITH THESE TIRES OR THE CAR!

WITH LESS THAN 2,000 MILES, TIRE PRESSURE SENSORS CONFLICT WITH PSI MANUAL PRESSURE GAUGE. THE SERVICE DEPARTMENT HAS INFLATED THE TIRES TO 36 PSI WHICH DOES NOT REGISTER AS SUCH, BUT LOWER BY 2-3 PSI. THE PRESSURE GAUGE SENSORS IS INCORRECT UNDER ALL DRIVINGS MODES. IT REMAINS UNRESOLVED.
