NHTSA Complaint #11376939 — 2013 TESLA MODEL S

BALL JOINT ON FRONT LEFT UPPER CONTROL ARM ASSEMBLY FAILED PREMATURELY AT APPROXIMATELY 80,000 MILES VEHICLE USAGE; SPECIFICALLY, IT SEPARATED SO AS TO CAUSE THE UCA (UPPER CONTROL ARM) TO DISCONNECT FROM FROM THE STEERING KNUCKLE DURING A LOW-SPEED PARKING LOT MANEUVER (THREE POINT 'Y' TURN) AT APPROXIMATELY 5 MPH OR LESS, WHICH CAUSED THE WHEEL TO TIP IN WORDS AGAINST THE STRUT ASSEMBLY. REPAIRED SUSPENSION BY REPLACING UPPER CONTROL ARM WITH INTEGRAL BALL JOINT. APPROXIMATELY 40,000 MILES LATER, THE BALL JOINT ON THE RIGHT HAND UPPER CONTROL ARM EXHIBITED EXTREME LOOSENESS AND CLUNKING SOUNDS FORCING ME TO REPLACE THE RH UCA / BALL JOINT ON THAT SIDE AS WELL. VEHICLE NOW HAS APPROXIMATELY 150,000 MILES VEHICLE USAGE AND THE SUSPENSION IS ONCE AGAIN EXHIBITING ABNORMAL CLUNKING NOISE (FROM THE LH FRONT CORNER) OVER BUMPS AT LOW SPEEDS THAT MAKES ME SUSPICIOUS THAT ADDITIONAL OR SAME BALL JOINTS ARE WEARING PREMATURELY. I AM A PROFESSIONAL MECHANICAL ENGINEER (WITH 27 YEARS INDUSTRY EXPERIENCE) RESPONSIBLE FOR PROPULSION SYSTEMS ON AGRICULTURAL HARVESTING VEHICLES AND CAN DEFINITIVELY STATE I HAVE NEVER ABUSED THIS VEHICLE. THE WEAR RATES ARE EXCESSIVE ON THE UCA BALL AND SOCKET CONNECTION WHICH DOES/COULD CAUSE BALL JOINT SEPARATION AND SUSPENSION FUNCTION/CONTROL.
