Power train

77 reports3 crashes1 fire
“SIMILAR TO A COMPLAINT FROM VIRGINIA IN 2012 I HAD AN ISSUE WITH STUTTERING AND A LACK OF ACCELERATION AND ONE DAY I STOPPED AT A STOP SIGN AND MY CAR SHUT OFF AND WHEN I TURNED IT BACK ON WOULD NOT MOVE FROM PARK AND HAS NOT MOVED SINCE I HAD IT TOWED TO MY HOUSE”

Air bags

26 reports8 crashes2 fires7 related recalls
“Airbag light has been lit for a while now for my 2004 Acura MDX. I originally took the car to Courtesy Acura for them to check what causing it. They told me that the sensor should be replaced and I paid $260+. After replacing sensor, the Airbag light still lit. They told me that they need to replace the front seatbelt buckles. One buckle (PART NO: 04813-S3V-A62ZC) arrived but the other one has been backordered for a while now (almost a year) and there's no ETA from American Honda on when the part (PART NO: 04816-S3V-A61ZC) will be available. This is a safety issue since the Airbag will not deploy in case of accident. Hope you guys can help me expedite the process and escalate the issue with American Honda. Thank you soo much!”

Electrical system

21 reports2 crashes3 fires1 related recall
“Multiple lights appear turn on and off indicated on dashboard, VGA, check engine light, and tire pressure system. I run a diagnostics and it says my Evap System had a code telling me to replace gas cap. I went to the auto parts store and purchased a new gas cap that is specifically for my vehicle. I turn the vehicle back on and code is still on. So I get the code erased with my diagnostic reader and the sensor turns off. But give it a few weeks and that light turns back with same code telling me to replace gas cap. I went back to return my gas cap at AutoZone. Then ordered an OEM gas cap for my vehicle and erased code and then code came back less than a month later. It can’t be two brand new parts, one was a universal part but specific to my vehicle. And second part was OEM specifically for my vehicle and from Acura/Honda parts department. So I don’t know what to do because repair said its a dumb code and just reset if I already replaced once. And don’t worry about the code indicator because the Evap system appears to be working. So it’s either an electrical issue or a glitch. I’m not comfortable with those options”

Engine and engine cooling

13 reports
“OVER A PERIOD OF TIME, BEGINNING ABOUT THE DATE AND VEHICLE MILEAGE STATED ABOVE, I EXPERIENCED A SHUDDER AND CORRESPONDING NOISE AS THE TRANSMISSION TRIED TO SHIFT GEARS. SIMILAR TO THE SENSATION OF DRIVING ACROSS CLOSELY-SPACED RUMBLE STRIPS, THE SHUDDER AND NOISE SEEMED TO VARY IN LENGTH OF TIME DEPENDING ON SPEED. THIS OCCURRED MANY TIMES BEFORE I BECAME CONCERNED AND STARTED RESEARCHING DURING WHICH I FOUND DOZENS OF SIMILAR ACCOUNTS IN VARIOUS ON-LINE FORUMS. EVENTUALLY I TOOK MY MDX TO THE DEALERSHIP FOR A DIAGNOSIS. DISAPPOINTINGLY SIMILAR TO MANY ACCOUNTS I READ ON THE INTERNET, AND DESPITE MY DESCRIPTION OF THE PROBLEM, THE ACURA DEALERSHIP WAS UNABLE TO REPRODUCE THE PROBLEM, FURTHER NOTING ALL 19 ITEMS ON THEIR MULTI-POINT INSPECTION REPORT AS "CHECKED AND OK", INCLUDING THE TRANSMISSION. SOON THEREAFTER, THE DRIVE TRAIN COMPLETELY FROZE UP AS I DISCOVERED AFTER STARTING THE CAR IN MY DRIVEWAY (THANKFULLY, NOT WHILE DRIVING THE CAR). DESPITE USING THE TRANSMISSION SHIFT LOCK RELEASE BUTTON (COINCIDENTALLY -?- THE SUBJECT OF A RECALL FOR WHICH I HAVE RECEIVED A NOTICE FROM ACURA), THE CAR REMAINS IMMOBILE BECAUSE I AM UNABLE TO GET THE CAR OUT OF…”
