SOMEHOW A WHEEL POPPED OFF OF MY 1999 JEEP GRAND CHEROKEE THAT I BOUGHT USED FROM A CERTIFIED JEEP DEALER A YEAR AND A HALF AGO (2002). I AM UNSURE HOW THIS HAPPENED, BUT ALL 5 LUG NUTS BROKE OFF, CAUSING THE WHEEL TO COMPLETELY POP OFF. LUCKILY, I WASN'T DRIVING MORE THAN 10 MPH WHEN THIS HAPPENED. I HAVE NEVER TAKEN MY CAR IN TO GET FIXED FOR ANYTHING DURING THE TIME I OWNED IT. I HAVE TAKEN IT IN FOR OIL CHANGES AND RESPONDED TO A COUPLE RECALLS ON MY CAR, BUT THAT'S IT. THE LAST MECHANIC WHO TOUCHED THIS CAR WAS FROM THE JEEP DEALERSHIP WHERE I BOUGHT IT. CURRENTLY, THE CAR HAS 37,000 MILES ON IT. AS I SAID BEFORE, I AM UNSURE HOW THIS HAPPENED. I HAVEN'T BEEN IN AN ACCIDENT, HAVEN'T HIT THE WHEELS ON ANYTHING, HAVEN'T ROTATED THE TIRES, ETC. THIS IS A MAJOR SAFETY CONCERN FOR ALL JEEP OWNERS. I'M CURRENTLY WORKING WITH THE JEEP DEALERSHIP TO FIGURE THIS OUT AND I PLAN ON CONTACTING THE MANUFACTURER ASAP. I WANT TO SURE THIS DOESN'T HAPPEN TO ME AGAIN AND I WANT TO BE SURE OTHER DRIVERS ARE NOT AT RISK. *LA
