NHTSA Complaint #11374041 — 2015 TESLA MODEL S

BATTERY PACK: THE RATE AT WHICH THE BATTERY PACK CHARGES WAS UNILATERALLY REDUCED BY TESLA AND TESLA REFUSES TO CORRECT THIS DEFECT UNDER THEIR WARRANTY. TESLA PROVIDED NO NOTICE IN THE ORIGINAL OWNER'S MANUAL (PAGE ATTACHED) NOR EXCLUSION IN THE WARRANTY (ATTACHED) THAT THIS WAS A POTENTIAL OUTCOME AS THE CAR AGED. THE WARRANTY PROVIDES THE FOLLOWING STATEMENT ABOUT DEGRADATION: "THE BATTERY, LIKE ALL LITHIUM-ION BATTERIES, WILL EXPERIENCE GRADUAL ENERGY OR POWER LOSS WITH TIME AND USE. LOSS OF BATTERY ENERGY OR POWER OVER TIME OR DUE TO OR RESULTING FROM BATTERY USAGE, IS NOT COVERED UNDER THIS BATTERY AND DRIVE UNIT LIMITED WARRANTY." THIS STATEMENT MAKES NO REFERENCE TO AN EXCLUSION FOR A REDUCTION IN THE PEAK RATE AT WHICH THE BATTERY CHARGES, WHICH IS THE DEFECT THAT I HAVE IDENTIFIED AND TESLA HAS REFUSED TO ADMIT IS A PROBLEM. TESLA'S UNILATERAL DECISION TO REDUCE THE RATES AT WHICH THE BATTERY CHARGES, WITHOUT WARNING, HAS A SUBSTANTIAL NEGATIVE IMPACT ON THE UTILITY AND USABILITY OF THE MOTOR VEHICLE. THE EXTENDED CHARGING TIMES MAKE LONGER DISTANCE (INTER-CITY) TRAVEL IMPRACTICAL AND INCONSISTENT WITH THE MARKETING OF THE MODEL S. FURTHERMORE, NEWER VERSIONS OF THE OWNER'S MANUAL INCLUDE A CLEAR AND UNEQUIVOCAL REFERENCE TO THE TYPE OF PROBLEM THAT I HAVE IDENTIFIED. THIS IS A CLEAR INDICATION THAT TESLA IDENTIFIED A PROBLEM *AFTER* THEY SOLD ME A VEHICLE AND THAT THEY SHOULD HAVE WARNED ME ABOUT THE POTENTIAL CHANGE IN THE "PEAK CHARGING RATE" AT THE TIME OF SALE. GIVEN THE COMPANY'S FAILURE TO EXCLUDE A REDUCTION IN THE PEAK CHARGING RATE FROM THE WARRANTY AT THE TIME OF MY PURCHASE AND THE SUBSTANTIAL NEGATIVE IMPACT THAT THIS HAS ON THE UTILITY OF THE VEHICLE, TESLA SHOULD BE ORDERED TO REPLACE MY CAPPED BATTERY PACK WITH A NEW BATTERY PACK.
