2006 NISSAN QUEST Unknown Or Other Problems

I PURCHASE A USED NISSAN QUEST IN JUNE 2016 COUPLE WEEKS LATER THE AIR BAG LIGHT STARTS FLASHING. ANOTHER THING IS THE CLUSTER THAT READS OVER HEARING AND MILES FLASHES AND TWITCHES. MY VEHICLE AT THE TIME OF PURCHASE HAD 121,246 MILES I'M THE SECOND OWNER. I TOOK TO COURTESY NISSAN AND WAS TOLD THAT THE FLASHING AIRBAG LIGHT IS NOTHING TO WORRY ABOUT, BUT I HAVE SEEN SEVERAL REVIEWS AND COMPLAINTS ABOUT THE AIRBAGS AND CAN'T STOP WORRYING SINCE THIS IS A FAMILY VEHICLE. ANOTHER ISSUE WITH THE VEHICLE IS THE SENSORS AND TIMING CHAIN GAVE UP SOON. ALSO AT TO REPLACE AIR CONDITIONING SYSTEM. THIS HAS BEEN A HOLE IN MY POCKET SINCE I PURCHASED. STATES THERE IS A RECALL BUT I'M NOT SURE

I HAVE A NISSAN QUEST 2006. MY MECHANIC TOLD ME THAT MY FRONT SUB-FRAME IS ALL ROTTEN AND NEEDS TO BE REPLACED

MY 2006 NISSAN QUEST HAS BAD JERKING IN THE TRANSMISSION WHEN THE GEARS CHANGE. IT DOES THIS WHEN IT BOTH GEARING UP AND SHIFTING DOWN AT ANY SPEED. THE JERKING IS VERY BAD WHEN ALSO COMING FROM REVERSE TO DRIVE. THIS IS A SAFETY CONCERN FOR ME AND MY FAMILY BECAUSE IF IT GIVES OUT ON THE EXPRESSWAY, IT COULD CAUSE AN ACCIDENT AND THAT PUTS MY FAMILY INCLUDING MY BABY IN DANGER. ALSO IF I AM STRANDED ON THE SIDE OF THE ROAD WITH MY CHILD IN EXTREME HEAT OR COLD THIS ALSO PUTS MY CHILD IN DANGER. THIS TRANSMISSION NEEDS TO BE RECALLED SEEING IS HOW I AM NOT THE ONLY ONE WITH THE COMPLAINT.

PERSISTENT LEAKING FROM PULL DOWN COAT HOOK AREA EVERY TIME IT RAINS. DEALER HAS TRIED 7 TIMES TO REMEDY WITH NO SUCCESS. *JB
