2006 Acura MDX engine problems

ENGINE

Car battery constantly draining resulting in having to jumpstart the car now every time to turn it on. Had the hands free system disconnected by the dealership over a year ago due to them stating it was drawing on battery however it has not changed and went from occasional need to jumpstart to every time you need to turn on car. Have had two new batteries installed and car looked at by dealership and only issue they found was hands free link drawing on battery so disconnected it.

The contact owns a 2006 Acura MDX. The contact stated while driving 40 MPH, the brake pedal was depressed and became stiff. In addition, the vehicle stalled, and the brake lights failed to illuminate. The contact stated that the instrument panel warning lights illuminate on and off. The gear stick would not shift gear as needed. In addition, the vehicle stability assist (VSA) warning light was the only warning light that remained illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 281,800.

ENGINE

LIKE OTHERS WITH THE 06 MDX I HAD TO HAVE THE MOTOR MOUNTS REPLACED. IT IS VERY POSSIBLE THE "JUDDER" AS HONDA CALLS THEM FROM THE TORQUE CONVERTER CAUSED THIS EVEN THOUGH I HAD THE COMPUTER SOFTWARE FIX. THIS BECAME AN ISSUE AS THE VIBRATIONS FROM THE BAD MOTOR MOUNTS DAMAGED THE FRONT RIGHT HALF SHAFT/AXIAL AND I WAS TOLD I WAS VERY LUCKY IT DID NOT BREAK WHILE I WAS DRIVING ON THE HIGHWAY.

ON JANUARY 14, 2014 MY DAUGHTER TOOK OUR 2006 MDX TO THE DEALER FOR MECHANICAL EVALUATION. THE CAR HAS BEEN HESITATING WHILE DRIVING, TRYING TO STOP THE CAR WHILE DRIVING. THE DIAGNOSE CAME BACK WITH THE FOLLOWING: TRANSMISSION NEEDS TO BE REPLACED AND ENGINE MOUNTS HAVE TO BE REPLACED AS WELL FOR THE TOTAL OF AROUND $7,200. IN OCTOBER 2008 (MILEAGE 55K) THE ORIGINAL TRANSMISSION HAS BEEN REPLACED WITH A RE-MANUFACTURED PART. DECEMBER 2009 ORIGINAL SYMPTOMS (WHINING NOISE, SHUTTER AT 40-50 MPH) HAVE RECURRED AND HAVE BEEN REPORTED TO DEALER'S MECHANICS. THEY COULD NOT SEE ANY PROBLEMS. DECEMBER 2010 WHINING NOISE STARTED COMING BACK AGAIN. DEALER'S MECHANICS COULD NOT FIND ANYTHING WRONG. NOW WE ARE FACED WITH A TRANSMISSION THAT IS MALFUNCTIONING PLUS ENGINE MOUNTS HAVE TO BE REPLACED. IN SPEAKING WITH ACURA'S CUSTOMER CARE I WAS INFORMED THAT THE TRANSMISSION REPLACED IN 2008 WAS NOT AN AUTHENTIC ACURA PART. I KEPT INSISTING ON MORE IN DEPTH EXPLANATION BUT DID NOT RECEIVE ANY. IT IS MY UNDERSTANDING THAT IMPROPERLY WORKING TRANSMISSION CAUSES DAMAGE TO ENGINE MOUNTS. IT SEEMS ACURA DEALER'S MECHANICS HAVE SOMEWHATHOW MISSED IT. ACURA IS NOT WILLING TO TAKE RESPONSIBILITY FOR ANY OF THEIR OMISSIONS. NOW THE CAR IS NO LONGER UNDER WARRANTY. ALL OF DESCRIBED INSTANCES ARE A HUGE SAFETY HAZARD. PUTTING IN NON-AUTHENTIC PARTS UNDER THE LABEL OF WARRANTY IS A FRAUDULENT STEP. ALL SERVICES HAVE BEEN PERFORMED AT JERRY DAMSON HONDA DEALERSHIP IN HUNTSVILLE, ALABAMA. I WOULD LIKE A FORMAL INVESTIGATION. IN ADDITION I FEEL THAT DEALERSHIP'S MECHANICS SHOULD GO THROUGH ADDITIONAL TRAINING TO AVOID FUTURE MISDIAGNOSES AND A REDUCE DANGER TO CONSUMERS.

ENGINE AND ENGINE COOLING

FIVE DAYS AFTER PASSING THE STATE CAR INSPECTION AT A HONDA DEALERSHIP, MY WIFE AND TWO SONS WERE DRIVING OUR MDX ON 146N WHEN THE CHECK ENGINE LIGHT CAME ON AND THE VEHICLE STALLED. AFTER HAVING THE CAR TOWED TWICE, FIRST TO A LOCAL GARAGE (AS IT WAS AFTER 7 PM AND ON THE WEEKEND) AND THEN TO THE ACURA DEALERSHIP, ACURA TECHNICIANS CONFIRMED THE DIAGNOSIS OF THE GARAGE AND STATED THAT A SPARK PLUG HAD BEEN SUCKED INTO THE ENGINE RENDERING THE VEHICLE UNUSABLE WITH SIGNIFICANT ENGINE DAMAGE. THE INITIAL COST ESTIMATE FOR REPAIR WAS $8,100 AS THE FOLLOWING PARTS NEEDED TO BE REPLACED: ENGINE SHORT BLOCK, CYLINDER HEAD, GASKET KITS, COIL PACK, SPARK PLUG(S), ETC. THE OWNER OF THE INDEPENDENT GARAGE HELPED MY WIFE TAKE SIDE-BY-SIDE PICTURES OF THE DAMAGE WHICH ARE AVAILABLE IF YOU WOULD LIKE TO SEE THEM. AS THE DAMAGED PARTS HAD BEEN TAKEN OUT OF MY VEHICLE, AGAINST MY REQUEST, THESE PICTURES ARE ALL THAT I HAVE TO SHOW THE EXTENT OF THE DAMAGE. I BELIEVE THIS IS A DEFECT IN THE VEHICLE AND SHOULD BE INVESTIGATED. PLEASE NOTE THAT ACURA DOES NOT INSPECT SPARK PLUGS UNTIL 100K MILES AND THIS DAMAGE OCCURRED AT 84,553 MILES. WE HAVE FOLLOWED THE MAINTENANCE SCHEDULE RECOMMENDED BY ACURA AND WERE JUST OUTSIDE OF OUR POWER TRAIN WARRANTY PERIOD AND BELIEVE THAT A LUXURY MANUFACTURER SHOULD STAND BEHIND THEIR PRODUCT ESPECIALLY FOR DAMAGE CAUSED BY A SPARK PLUG THAT IS NOT REQUIRED TO BE INSPECTED FOR ANOTHER 15,000 MILES.

ENGINE AND ENGINE COOLING:ENGINE

TOPIC: UNCOMMANDED ACCELERATION; LACK OF ACCELERATION; INCIDENTS OCCURRED OVER THE COURSE OF 3 WEEKS (USED 2006 ACURA MDX PURCHASED ON APRIL 12, 2010). SHORTLY AFTER PURCHASE, VEHICLE EXHIBITED "STUMBLE" WHEN ACCELERATOR WAS PUSHED. THAT IS, THE ENGINE RPM DECREASED WITH INCREASING PEDAL PRESSURE. PRESSING DOWN AGGRESSIVELY RESULTED IN ENGINE IDLE CONDITION. THIS OCCURRED 0.5 MILES FROM HOME. PROBLEM DID NOT CONTINUE THE NEXT MORNING. ON MAY 3, 2010, WHILE COASTING THROUGH AN INTERSECTION AT APPROXIMATELY 35MPH, VEHICLE SUDDENLY ACCELERATED WITHOUT PEDAL INPUT. CRUISE CONTROL LIGHT WAS OBSERVED ON (CRUISE CONTROL HAD NOT BEEN ENGAGED PRIOR TO INCIDENT). LIGHT BRAKE PRESSURE STOPPED ACCELERATION AND VEHICLE RETURNED TO NORMAL OPERATION. ON MAY 6, 2010, VEHICLE "STUMBLE" RE-OCCURRED. PULLING THROUGH AN INTERSECTION WHILE PRESSING ON ACCELERATOR, VEHICLE RPM DROPPED. MORE ACCELERATOR PRESSURE RESULTED IN MORE RPM DROP. PULLED TO SIDE OF ROAD AND STOPPED. WITH VEHICLE IN NEUTRAL OR PARK, ENGINE RESPONDS NORMALLY TO ACCELERATOR. PUTTING VEHICLE IN ANY FORWARD GEAR, PROBLEM PERSISTS. I WAS ABLE TO SLOWLY ACCELERATE WITH VERY GENTLE ACCELERATOR PRESSURE, BUT RATE OF ACCELERATION WAS VERY SLOW AND POTENTIALLY DANGEROUS DUE TO HEAVY RUSH HOUR TRAFFIC. I WAS ABLE TO SLOWLY DRIVE THE VEHICLE APPROXIMATELY 3 MILES BACK TO THE USED CAR DEALER WHERE THE VEHICLE WAS BOUGHT. AT END OF TRIP, VEHICLE WAS UNABLE TO CLIMB A MODEST INCLINE AND I HAD TO STOP. TURNED OFF ENGINE HOPING THAT PROBLEM WOULD CLEAR. WAITED SEVERAL MINUTES AND TRIED TO RE-START. TOOK SEVERAL ATTEMPTS BEFORE ENGINE WOULD "CATCH" AND RUN NORMALLY. WAS ABLE TO SLOWLY CLIMB THE INCLINE BACK TO THE CAR LOT. PROBLEM PERSISTED AT USED CAR LOT. VEHICLE WAS TOWED THE NEXT MORNING TO ACURA DEALERSHIP IN CHAPEL HILL, NC. PROBLEM CLEARED AND DEALER WAS UNABLE TO OBSERVE SYMPTOMS. DEALER CLAIMS THAT THERE ARE NO ANOMALOUS COMPUTER CODES. I BELIEVE VEHICLE IS UNSAFE TO DRIVE.
