Air bags

“Warning Passenger Air Bag OFF Light is lit with a passenger in the seat. Diagnostics run by ASE repair shop & with no error codes displaying. Moving passenger seat forward & back, shut the light off & on. Concerned that passenger Air Bag may not deploy when the light is on. Air bag sensor in part of the passenger seat and entire seat requires replacement, part is discontinued. Seeking a replacement seat from junkyard, if not will sell vehicle.”
Structure

“Sunroof drain tube leaks water down passenger side A-pillar onto body control module above glovebox causing damage to system, electrical connections, air bag, engine light to activate, vehicle going into limp mode. Drain is functioning and not stopped up. Dealer unable to correct long term using OEM parts available for replacement. Vehicle and invoices available for inspection. When leaking, water runs down A-pillar, onto computer module above glove box, and into passenger foot well.”
Electrical system
7 reports1 crash
“Immediately when I started driving, the sensors on my dashboard started lighting up. First the air pressure sensor, then the Tire serve sensor, and finally the key sensor. My turn signals were malfunctioning. They would go on and off without me triggering them. Then every time I came to a stop and accelerated again, my car would jerk back. I eventually pulled over and my car wouldn’t even turn off. I had to put the key fob in the key slot to get the car to turn off. Then, the car would not start back up. I had to have the car towed to the Dealership. When I arrived at the Dealership, they told me that there were two other cars there having similar issues caused by rain water getting into the electrical. Here is the diagnosis they gave me: UPON INSPECTION AND SITTING IN VEHICLE CAN SMELL AND FEEL DAMPNESS FROM CARPET. FURTHER INSPECTION FOUND WATER FROM SUNROOF DRAIN TUBES LEAKING WATER INTO THE BODY CONTROL COMPUTER AND CAUSED ELECTRICAL SHORT CIRCUIT WITH INTELLIGENT KEY SYSTEM AND IGNITION SYSTEM. PERFORMED ELECTRICAL TEST AND TRACED SOURCE OF FAILURE TO THE BODY CONTROL UNIT. (THE BODY CONTROL MODULE CONTROLS KEYS, DOOR LOCKS, VEHICLE IGNITION START, AND…”
Visibility/wiper
4 reports
“Sunroof drain failure causing rain water from the outside of the vehicle to enter the interior flooding the passenger side going from the front seats to the back seats. Due to the sunroof drain defect, the flooding of the interior causes the water to get into the body control module impacting the electronics which can result in numerous failures in the vehicle making it dangerous to drive. There are numerous videos on YouTube and posts on online forums describing this very issue which is extremely common with the G37. Infiniti dealer confirms the issue, but takes absolutely no responsibility. The cost of the repairs to the sunroof drain and body control module are completely placed on the consumer.”

“ON THE SUNNY AND DRY MORNING OF DECEMBER 9, 2020, I PROCEEDED TO ALPINE CEMETERY, PERTH AMBOY, NJ TO HONOR MY MOTHER'S GRAVE SITE AND HER ANNIVERSARY. AS I PASSED THE GATE ENTRANCE TO THE CEMETERY, I TURNED RIGHT; AS I HAVE ALWAYS DONE IN PREVIOUS YEARS. ONCE I TURNED TO THE RIGHT I NOTICED THAT THERE WAS A BURIAL PROCESSION, WITH THE FUNERAL HEARSE OBSTRUCTING THE ENTIRE VEHICLE PATH. SINCE I COULD NOT DRIVE FORWARD, THE ONLY RECOURSE I HAD WAS TO TURN AROUND AND FIND ANOTHER VEHICLE PATH. ONCE I HAD TAKEN THE NEW PATH, WHICH I BELIEVE WOULD LEAD ME TO MY MOTHER'S GRAVE SITE, I REALIZED THAT I COULD NOT REACH HER GRAVE SITE SINCE IT WAS FURTHER UP THE NEW PATH. ONCE I TURNED THE VEHICLE TO THE LEFT; THE VEHICLE WENT AUTOMATICALLY BACKWARDS THEN FORWARDS WITH THE SENSATION OF TAKING OFF THE GROUND LIKE AN AIRPLANE. I HAD NO CONTROL OF THE VEHICLE AND THE VEHICLE PROCEEDED AUTOMATICALLY HITTING NUMEROUS TOMB STONES UNTIL ONE TOMB STONE STOPPED THE VEHICLE. THIS FAILURE OCCURRED NUMEROUS TIMES UNTIL A 3FT TOMB STONE STOPPED THE VEHICLE. THE VEHICLE WAS TAKEN TO THE CAR REPAIR SHOP, INSTRUCTED BY NJM INSURANCE; VNF AUTO BODY 732-321-6919, 20 PROSPECT STREET, METUCHEN NJ 08840.”
Service brakes
4 reports2 crashes
“THE PARKING BRAKE CABLE, AS SET FROM THE FACTORY, IS WAY TOO LOOSE TO HOLD THE CAR ON EVEN A SLIGHT INCLINE. THE PARKING BRAKE HANDLE TAKES EXCESSIVE FORCE TO PULL FAR ENOUGH TO HOLD THE VEHICLE FROM ROLLING. THE DEALER REFUSES TO ADJUST THE CABLE TENSION UNDER WARRANTY STATING IT IS NOT COVERED. THIS IS MY SECOND 2013 G37 WITH THIS ISSUE.”
