I love this vehicle but it's suddenly started having a rough idle and with a scan tool detects multiple misfires and several codes due to timing, in which case the timing chain has been worn out call the dealership to see if the timing chain recall for the m56 was done to my car they said it was VIN specific now I am stuck with a vehicle that is very dangerous to be driven.

HERE IS A COPY OF A BLOG. I HAVE BOUGHT 6 BATTERY'S IN 4 YEARS. I HAVE BEEN STRANDED WITH THE FAMILY LATE AT NIGHT PAID FOR MANY TOW TRUCKS. TAKEN MY CAR TO INFINITY DEALERS WITH NO SUCCESS. PLEASE READ THIS BLOG.. HTTPS://X.INFINITIHELP.COM/FORUM/SHOWTHREAD.PHP/2011-M37X-BATTERY-PROBLEMSI-7942.HTML 4 PAGES OF PEOLPLE HAVING THE SAME ISSUE WITH THERE INFINITI. I AM TOLD I HAVE TO PAY FOR A 1200 MODULE THAT MAYBE WILL FIX THE PROBLEM. THIS IS NOT A PROBLEM THAT ANYONE WOULD NOTICE IN THE FIRST COUPLE OF YEARS BECAUSE YOU THINK THE BATTERY IS AT FAULT. INFINITI FIX THE ISSUE IN 2014 BUT DID NOT DO A RECALL ON PRIOR M37/56.

I STARTED THE CAR UP AND STARTED TO DRIVE TO WORK ABOUT 3 MILES INTO DRIVING THE CHECK ENGINE LIGHT CAME ON FOLLOWED BY REVS WITH NO POWER OR SPEED GAIN AND THE VEHICLE WAS GIVING ME AROUND 15MPH TO THE POINT WHERE I COULDN'T GAIN MUCH MORE SPEED AND HAD TO PULL OFF THE ROAD. THERE WAS A VOLUNTARY SERVICE CAMPAIGN FOR THE TIMING CHAIN BUT IT HAS SINCE EXPIRED AND NOW I AM STUCK WITH THE REPAIRS.

Service brakes
WHEN YOU GO TO APPLY THE BRAKE IT OFTEN LOCKS UP AND STOPS IMMEDIATELY. THIS IS AN ISSUE THAT COMES AND GOES. IT ALSO AT THE SAME TIME IT IS STOPPING ABRUPTLY WITHOUT APPLYING THE BRAKE COMPLETELY IT WILL DO THE OPPOSITE AND THE BRAKE WILL DEFLATE ALL THE WAY TO THE FLOOR BEFORE STOPPING. WHILE STOP IT WILL LOSE PRESSURE AND THE BRAKE WILL SLOWLY GO TO THE FLOOR. HAVE TAKEN IT SEVERAL PLACES AND THEY CAN NOT FIX. HAVE HAD ALMOST ALL BRAKE PARTS REPLACED AND OR CHECKED. THIS HAPPENS EVER TIME BRAKES ARE APPLIED FOR A WEEK OR SO THEN GOES AWAY THEN COMES BACK PERIODICALLY. HAS BEEN HAPPENING FOR OVER A YEAR. MECHANICS HAVE ENCOIUNTERED THE ISSUE AND CAN NOT FIGURE OUT WHAT IS CAUSING IT,…

Electronic stability control (esc)
4WAS AND STABILITY CONTROL WARNING LIGHTS COME ON WHEN DRIVING OVER ROUGH ASPHALT, OR TURNING RIGHT OR LEFT AND ROAD IS ROUGH. THE REAR OF THE CAR FEELS UNSTABLE AND STEERING WHEEL IS OFF-CENTER. THE LIGHTS ARE ON UNTIL THE CAR IS TURNED OFF. WHEN THE CAR IS TURNED ON AGAIN AND BEFORE THE WARNING SYMBOLS COME BACK ON, THE STEERING WHEEL IS CENTERED AND CAR DRIVES FINE. INFINITI HAS RECOMMENDED REPLACING THE HICAS ACTUATOR. THIS HAS NOT RESOLVED THE PROBLEM FOR INFINITI OWNERS AND ARE THEN RECOMMENDED TO REPLACE THE 4WAS CONTROL BOX. REPLACING THE CONTROL BOX ALSO DOES NOT RESOLVE THE ISSUE. I HAVE READ AND JOINED A NISSAN/INFINITI FORUM WHERE OWNERS THAT HAVE THIS EXACT PROBLEM HAVE…
