Verbatim excerpts from NHTSA complaints, by component

Power train

17 reports2 crashes
“VEHICLE HAS HESITATION DURING ACCELERATION, IT LAGS AND TRANSMISSION IS UNRESPONSIVE MOST OF THE TIMES. THERE ARE OTHER TIMES THAT THE VEHICLES TRANSMISSION WILL DOWNSHIFT AND REV UP WHILE COASTING DOWN HILL WHILE FOOT IS OFF ACCELERATOR. VEHICLE ONLY HAS 59K MILES ON IT AND SHOULD NOT BE HAVING THIS ISSUE. IT'S LIKE THE TRANSMISSION JUST DOESN'T KNOW WHAT GEAR IT SHOULD BE IN. INFINITI NEEDS TO FIX A CLEAR DESIGN PROBLEM!”

Steering

6 reports
“I'D LIKE TO REPORT A PROBLEM THAT HAS OCCURRED WITH MY 2011 INFINITI M37 WHICH SEEMS TO BE PRETTY FATAL. THE PLASTIC COVER THAT COVERS THE STEERING WHEEL'S ROD CRACKS OPEN WHEN THE STEERING WHEEL IS TILTED TO A LOWER POSITION. ONCE THE COVER IS CRACKED, STEERING WHEEL RUBS ON TO THE PLASTIC BEHIND IT AND MAKES THE STEERING WHEEL NEARLY IMPOSSIBLE TO STEER. IF SOMEONE FACED THIS ISSUE BY CHANGING THEIR STEERING WHEEL POSITION WHILE DRIVING, IT WILL SURELY LEAD TO A FATAL ACCIDENT. THIS ISSUE SEEMS TO HAPPEN TO OTHER VEHICLES AS WELL ACCORDING TO THE FORUM LINK ATTACHED: HTTP://FORUMS.NICOCLUB.COM/STEERING-WHEEL-RUBBING-PLASTIC-HOUSING-T609452.HTML I HAVE TRIED TO CONTACT INFINITI REGARDING THIS ISSUE AND THE ANSWER I RECEIVED WAS THAT THERE'S NOTHING THEY COULD DO SINCE I AM OUT OF WARRANTY. HOWEVER, THAT PART OF THE VEHICLE IS BARELY USED NOR TOUCHED WHICH MAKES THIS A MANUFACTURING DEFECT BUT NO ONE WANTS TO BE RESPONSIBLE FOR THIS.”

Vehicle speed control

5 reports1 crash
“I HAVE SEVERAL ISSUES. THE STEERING WHEEL PEELS. I HAVE A CRACKED DRIVER'S SIDE LEATHER INTERIOR DOOR. THE CAR STARTED JERKING REALLY BAD ON A CITY STREET, I COULDN'T GO OVER 35 MPH. MY 4WAS MOTOR HAS GONE BAD! INFINITI DEALERSHIP, CANNOT EXPLAIN WHAT WOULD HAVE CAUSED THE MOTOR, TO GO BAD. ALL OF THE CAR'S SAFETY FEATURES, ARE CONNECTED TO THIS 4WAS MOTOR. SO, WHEN THAT 4WAS LIGHT COMES ON, ALL OF THE SAFETY FEATURES ARE TURNED OFF. THIS INCLUDES: INTELLIGENT CRUISE CONTROL, 4WAS, BLIND SPOT DETECTION, LANE DEPARTURE, STABILITY CONTROL, AND SPORT MODE! THE COST IS $8500! I PURCHASED THIS CAR IN 2011.”
