I PURCHASED THIS VEHICLE FROM A PRIVATE AUCTION IN HESPERIA, CA AROUND AUGUST OF 2020 AND I AM CURRENTLY THE REGISTERED OWNER AS OF TODAY. ABOUT A MONTH INTO THE PURCHASE I NOTICE THE CAR JERK AND BRAKE UNUSUALLY WHILE IN MOTION. I DIDN'T KNOW WHAT EXACTLY HAPPENED AT THE TIME SO I IGNORED IT FOR THE MOMENT. THEN ABOUT ANOTHER MONTH AFTER THAT INCIDENT MY WIFE, KIDS AND I WERE TRAVELING ABOUT 70 MPH ON THE 15FWY HEADED SOUTH AND THIS TIME IT HAPPENED ONCE AGAIN AND MORE AGGRESSIVELY DUE TO IS TRAVELING AT A MUCH GREATER SPEED AND DID JERK A LOT HARDER ALMOST MAKING MY WIFE LOSE CONTROL. LUCKILY SHE WAS ALERT AND PULLED OVER TO THE SHOULDER RIGHT AWAY AND THAT'S WHEN WE NOTICED A NEW LIGHT ON THE I DASH HAD ILLUMINATED. WE SEE THE ACRONYM (VSA) ILLUMINATE AND I HAD NEVER SEEN THIS PARTICULAR LIGHT BEFORE SO I THEN START TO RESEARCH IT. I FIND OUT IT'S PART OF AN ANTI LOCK FEATURE AND IT'S SUFFICE WHEN DEALING WITH CURVY ROADS AND HELPS WITH TRACTION WHICH GIVES SMOOTHER TURNS WHILE DRIVING AND GIVES BETTER CONTROL OF THE VEHICLE. I ALSO READ IT'S BEST TO KEEP THIS FEATURE OFF WHILE COMMUTING IN YOUR REGULAR EVERYDAY TRANSIT. SO AS MONTHS GO BY IT HAPPENED TO ME A GOOD HANDFUL OF TIMES AFTERWARDS BUT AT SLOWER SPEEDS AND THIS TIME THE LIGHT WOULD NOT GO OFF WHEN I TRIED TURNING OFF THE VSA CONTROL BUTTON ON THE DRIVER SIDE DASH. I DIDN'T HAVE MEANS TO REPAIR THIS PART SO I PUT IT OFF ONCE AGAIN. WELL COMING TO A MORE RECENT EVENT WHICH RESULTED IN MYSELF LOSING CONTROL WHILE ON MY WAY HOME FROM WORK AT 11:30PM AT NIGHT AND TOTALING THE VEHICLE AS WELL AS FLIPPING THE VEHICLE UNTIL IT CAME TO A REST ON ITS SIDE. I STRONGLY BELIEVE THE VSA FEATURE MALFUNCTIONED MADE ME LOSE CONTROL AT 62-65 MPH ALMOST CLAIMING MY LIFE. I STRONGLY BELIEVE IT IS RESPONSIBLE FOR MY RECENT ACCIDENT WHICH COULD HAVE BEEN LIFE THREATENING AND HAS CAUSED FINANCIAL STRESS UPON MY FAMILY.

DRIVER SIDE POWER WINDOW CONTROL UNIT CONNECTOR FAILS AFTER YEARS IN SERVICE. THE CONTROL UNIT IS MOUNTED ON DOOR WITH BRACKET AND TWO SCREW WHICH PUTS UNDUE PRESSURE ON THE CONNECTOR BY PUSHING IT AGAINST THE BODY. OVER THE TIME PLASTIC CONNECTOR (DUE TO CREEP EFFECT) WILL GIVE AWAY AND BECOME LOOSE PREVENTING PROPER CONTACT WHICH WILL DISABLE THE OPERATION OF DRIVER SIDE POWER WINDOW. I LEARNED IT HARD WAY BY SPENDING LOTS OF MONEY CHANGING ALL PARTS (CONTROL MODULE, WINDOW MOTOR AND DRIVER MULTIPLEX SWITCH) FOR NO REASON. *TR

AFTER PLACING VEHICLE IN PARK, I WAS UNABLE TO REMOVE THE KEY FROM THE IGNITION. THE IGNITION KEY FAILED TO ALIGN WITH SLOT SO KEY COULD BE REMOVED. WHEN I ATTEMPTED TO RESTART THE CAR, IT FAILED TO START. I BELIEVE THE PROBLEM IS SOMEHOW LINKED BETWEEN THE IGNITION AND THE TRANSMISSION/GEAR SHIFT. RECENTLY, WHEN SHIFTING INTO PARK AND DRIVE THE GEAR SHIFT MET WITH RESISTANCE. I'M OUT OF TOWN (APPROX 100 MILES) AND AFRAID TO STOP ANYWHERE UNTIL I REACH MY DEALER. HAD NEW TRANSMISSION INSTALLED WITHIN THE LAST TWO YEARS. POSTING THIS NOTICE FROM HOTEL'S COMPUTER, HEADING TO DEALER (MCGRAPH ACURA, WESTMOUNT,IL.) TO DIAGNOSE AND HOPEFULLY CORRECT PROBLEM. *TR

I BROUGHT MY CAR IN FOR RECALL FOR THE SHIFT INTERLOCK 7250A2. A REPAIR OR REPLACEMENT WAS DONE BY POHANKA ACURA SERVICE. AFTER THE RECALL FIX, I COULD STILL PULL THE KEY FROM THE IGNITION WHILE THE CARE IS IN DRIVE. I CALLED THE DEALERSHIP AND THEY ARE TRYING TO FIX IT AGAIN TODAY. I AM COMPLAINING THAT THE INITIAL FIX PERFORMED BY THE DEALERSHIP WAS INSUFFICIENT. I CAN FORWARD A YOUTUBE LINK OF THE VIDEO IF NEEDED. *TR

HAVE BOOMING SOUND COMING FROM THE SUB-WOOFER IN THE REAR. SOUNDS DEAFENING, QUITE LOUD AND BOOMING. TOOK IT IN BECAUSE I HAD A WARRANTY AND THEY DID NOTHING- DIDN'T NOTICE THEY DIDN'T FIX IT TILL I GOT HOME AS I DIDN'T PICK UP THE CAR. TOOK IT BACK AND THEY SAID THEY REPLACED THE SUB-WOOFER. ON SATURDAY DRIVING HOME AND HAD THE CAR RUNNING, WENT TO BACK TO REMOVE SOMETHING AND HEARD THIS CRAZY NOISE. I THOUGH IT WAS COMING FROM THE TAIL PIPE, THAT'S HOW LOUD IT WAS UNTIL I OPENED THE BACK AND REALIZE IT WAS THE SUB-WOOFER AGAIN! I HAVE SEEN THAT A LOT OF OTHER PEOPLE ARE HAVING THE SAME PROBLEM, AND NOT SURE WHY THERE ISN'T A PERMANENT FIX FROM ACURA REGARDING THIS. THE DEALERSHIP, WILL IMPLY ITS YOUR CD'S ETC, BUT ITS NOT, IT SOUNDS CRAZY WHETHER ITS THE RADIO OR EVEN IF YOU HAVE THE BASS LOWERED TO HELP WITH THE NOISE. *TR

I DON'T KNOW IF THIS COUNTS BUT HERE I GO. I PURCHASED MY NEW ACURA 2005 MDX OVER 3 MONTHS AGO. I KNOW THIS IS NOT A RECALL BUT WANTED TO MAKE YOU AWARE OF A BOOMING SOUND THAT IS COMING FROM THE SUB-WOOFER IN THE REAR. ITS ALMOST IF THE WOOFER IS LOOSE INSIDE THE REAR OF THE CAR. I GUESS A LOT OF OTHER 2005 MDX OWNERS ARE HAVING THE SAME PROBLEM. ITS A PROCEDURE WHERE THE INTERIOR HAS TO BE TAKEN OFF AND AN ADHESIVE IS PUT AROUND THE SUBWOOFER TO SECURE IT TO THE VEHICLE. YOU MIGHT WANT TO REPORT THIS TO ACURA. I HOPE THIS HELPS. *JB
