Owner report 10750334 · 2015-08-21 (August 21, 2015)
RECENTLY I WAS SITTING AT A STOPLIGHT ABOUT 3RD IN LINE BEHIND A FORD EXPLORER. I LIVE IN ATLANTA SO STOPLIGHTS ARE EXTRAORDINARILY LONG. I HAD THE CAR IN DRIVE OBVIOUSLY AND MY FOOT FIRMLY ON THE BRAKE. ABOUT 5 MINUTES INTO THE RED LIGHT MY CAR STARTS TO SLOWLY MOVE FORWARD WHILE MY FOOT WAS STILL FIRMLY ON THE BRAKE. THE MOVEMENT WAS SIMILAR TO IF THE BRAKE HAD BEEN RELEASED AND THE CAR WAS COASTING IN DRIVE. FORTUNATELY I LEFT SOME DISTANCE BETWEEN MYSELF AND THE EXPLORER IN FRONT OF ME, BUT OBVIOUSLY A MOMENT OF PANIC COMES OVER ME WHEN MY …

CAME TO A SLOW STOP AT A RED LIGHT IN MY 2015 INFINITI Q50. MY FOOT WAS DIRECTLY ON THE BRAKE. WITHIN SECONDS THE CAR BEGAN TO PULL FORWARD AND I APPLIED ADDITIONAL PRESSURE ON THE BRAKES BY USING BOTH FEET. THE ENGINE WAS RACING OUT OF CONTROL AND THE TIRES WERE SCREECHING. SIFTING THE GEARS DID NOT HELP. I LET OFF THE BRAKE AND TURNED RIGHT INSTEAD OF STRAIGHT IN ORDER TO AVOID HITTING CARS. SHIFTING VIOLENTLKY THE CAR FINALLY WENT BACK TO NORMAL. THE DEALER DENIES THE CAR IS AT FAULT AND SAYS THIS IS A CASE OF HUMAN ERROR.

Owner report 10787579 · 2015-11-02 (November 2, 2015)
ON NUMEROUS OCCASIONS WHILE IN MOTION AT VARIOUS SPEEDS THE VEHICLE WILL AUDIBLY ALERT, BRAKE, STEER, AND DEADEN THROTTLE RESPONSE. THESE ARE RELATED TO ENHANCED SAFETY FEATURES OF THE VEHICLE. THE PROBLEM IS THAT THESE OCCUR WHEN THERE IS NOTHING TO AVOID OR ANY DANGER PRESENT. THESE HAVE OCCURRED AT HIGH SPEEDS AND IN SITUATIONS WHERE THEY COULD HAVE CAUSED AN ACCIDENT. MY LOCAL DEALERSHIP BLAMED ALL ISSUES ON THE PLACEMENT OF AN EZ PASS TRANSPONDER. I FIND THIS TO BE COMPLETELY ABSURD. INFINITI CUSTOMER CARE WILL NOT ASSIST. I HAVE DI…

Owner report 10875905 · 2016-06-22 (June 22, 2016)
WHEN THE CAR HAD 8K MILES ON IT, THE FRONT ROTORS WENT BAD I.E. DEFECTED AND INFINITI DEALER FIXED THEM AND REPLACED THE FRONT PADS AS A WARRANTY ITEM. NOW AT UNDER 24K MILES, THE REAR BREAKS ARE GONE BAD BUT THE DEALER AND INFINITI CORP. ARE DENYING THEY'RE DEFECTED AND REFUSE TO FIX THEM. THIS IS MY 3RD INFINITI, I HAD BEFORE A 2008 G35S, AND 2013 G37S, I DRIVE MY CAR REGULARLY IN TOWN AND HIGHWAY, NO EXCESSIVE DRIVING, AND MY REAR BRAKES NEVER WENT BAD ON OTHER INFINITI CARS UNDER 24K MILES. I BELIEVE THE REAR BREAKS HAVE PROBLEMS JUST LIKE …
