What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2012 INFINITI M37, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
When the steering wheel is adjusted up, down or the telescopic adjustment is used a loud pop is heard, the casing comes apart and it is no longer possible to turn the wheel left or right.
WHEN THE STEERING WHEEL IS ADJUSTED TO A NORMAL SETTING THE CASING POPS AND IT BECOMES VERY DIFFICULT TO TURN THE WHEEL.
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
The front passenger airbag warning light came on with a dash warning flashing light. I isolated the fault to the passenger seat weight sensor, which prevents the airbag from deploying when a passenger of less than 90 pounds is sensed in the front seat. The time from the onset of the warning light to discovery of the actual fault was less than a week and this was facilitated by a mechanic with a sophisticated enough OBD reader to flesh out Infiniti codes. I called my local Infiniti dealer in Tacoma, WA and they were able to supply a part number but it has been discontinued for the 2011-2013 Infiniti M37 models. Without this sensor working, the passenger airbag may not deploy in the event of a collision, and that is unsatisfactory/downright unacceptable. These cars will operate for 20 plus years and are otherwise engineered to last 200/000 miles. I have 90,000 miles on the odometer and the car is otherwise in great shape, but I may be forced to scrap it if I can't resolve the weight sensor malfunction.

TOTAL LACK OF ACCELERATION WHEN PASSING. THERE IS A 2-3 SECOND DELAY PRIOR TO THE DOWNSHIFT AND I'M NEVER SURE WHEN THE ACCELERATION WILL TAKE PLACE. THIS PROBLEM OCCURS FROM 50MPH AND UP. I HAVE HAD THIS PROBLEM SINCE I PURCHASED THE CAR AND IT HAS NOT CHANGED OVER TIME. INFINITY REPROGRAMMED THE ECM AND NO IMPROVEMENT WAS NOTED. I GAVE UP ON THEIR SERVICE SUPPORT. THANKS

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
EXPERIENCED VERY SLOW ACCELERATOR RESPONSE SINCE VEHICLE WAS BRAND NEW. NOW IN ADDITION TO THAT THE CAR IS HAVING HORRIBLE PROBLEMS WHILE BRAKING, TRANSMISSION BANGS OUT OF GEAR, THE CAR ALSO DROPS MULTIPLE GEARS AT ONCE WHICH CAUSES A VERY HIGH REV OF ENGINE. IT FEELS SO ROUGH IT MAKES IT FEEL LIKE YOU'VE BEEN HIT FROM BEHIND. THIS CAR FEELS VERY UNSAFE TO DRIVE. THERE MUST BE FAULTY TRANSMISSIONS OR SOFTWARE HERE. *TR
9/25/2012-I AM HAVING SOME SEVERE ISSUES WITH THE BRAKES ON THE M37. YESTERDAY I JUST AVOIDED AN ACCIDENT WITH THE BACK END OF A UPS TRUCK AS THE CAR WOULD NOT STOP. THIS IS THE THIRD TIME THAT SOMETHING LIKE THIS HAS HAPPENED WITH THE BRAKES. EACH TIME IT HAS BEEN WHILE TRAVELING ABOVE 50 MPH AND TRYING TO STOP QUICKLY. THE REACTION OF THE CAR IS SIMILAR TO THAT OF AN ANTI-LOCK BRAKE SYSTEM WHEN YOU ARE ON WET OR ICY ROADS. HOWEVER, THE ROADS HAVE BEEN PERFECTLY DRY AND THE SUN IS SHINING. WHEN TRYING TO USE THE BRAKE TO DECELERATE THE PEDAL WILL PULSATE AND THE ENGINE RPM WILL INCREASE SIGNIFICANTLY. BASICALLY THE CAR DRIVES THROUGH THE DRIVER'S COMMAND TO STOP. LAST NIGHT IT WAS SO BAD THAT I HAD TO SWERVE INTO THE ONCOMING LANE BECAUSE IT WOULD NOT STOP IN TIME TO PREVENT ME FROM REAR-ENDING THE UPS TRUCK. I AM A VERY SOUND DRIVER THAT DOES NOT TAIL GATE AND THIS CAR HAS DONE THIS NOW 3 TIMES. THE OTHER TWO TIMES I WAS TRYING TO AVOID ANIMALS THAT SHOT OUT IN FRONT OF ME. I SEE THAT THIS HAS BEEN A KNOWN PROBLEM ON SEVERAL MODEL YEAR CARS FOR INFINITI. *TR

Interior & seats
Reports naming seats, latches, locks, linkages and interior fittings.

Passenger Air Bag Sensor Failed. Concerned Passenger Airbag will not deploy when passengers are in the car. This is a Very Known and Problematic issue with Infiniti and Infiniti will not address this critical safety issue. Infiniti says repairs would be the owner responsibility and cost in excess of $8,000. This is a critical safety issue and needs to be addressed by Infiniti before someone gets hurt.
