Approximately 3 months ago I went to start the medic and it would not start. No lights or any other accessories were left on. The car was jumped and started. Being the car was 4 years old and I had reviews of battery problems in the medic, I had the battery replaced. About two weeks later it would not start again. It was jumped again and taken to an auto repair shop to be tested. The repair shop said the battery was weak, so it was replaced again. It's been about 2 months now and today when I went to start it, the battery was dead again. Three batteries do not go bad that quickly, there is a problem with the electrical system in this vehicle. I have noticed other complaints with this same issue on this web site. *tr

Acura mdx 2009 happened two times within 3 weeks. While driving car lost all electric, entire dashboard went dead, no headlights, no door/trunk locks, no navigation, no dvd, no radio, car stalled and couldn't be started again. Had to be towed. Second time same thing happened while approaching an intersection and trying to make a left turn. Car was towed again. *tr

My mdx has only 62,400 miles and today I got a message "check starter system" due to the hfl module is draining the battery. Luckily the car was in my garage at the time. I had to charge the battery so I could start the car. All the info I have read online states the the hfl module gets real hot and can cause fire. My garage is under my bedroom. This is a part made by johnson controls, Acura needs to recall this item.

The bluetooth module drains the battery when the vehicle is turned off and I am afraid that my vehicle could be turned off by draining the battery when running causing a safety issue. I have registered the case with Acura customer server and have not helped me with the free replacement. The Acura case number is [xxx] 2009 Acura mdx AWD VIN: 2hnyd28679h[xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tt

The battery has been drained on three separate occasions this year (2021). I replaced the battery after the first occurrence. Each time I have had to use a battery jump to restart the vehicle which sufficed to get it operating and return home. On the last occasion, the car started to display dash board warning messages before arriving at home after driving only 15 miles. This came with a fully charged battery installed to get the car restarted. Previously I could see no error codes, but following this latest incident the AWD error code 77-01 is displayed by an OBD reader. The vehicle began to run roughly and flashed many dashboard warnings as the battery began to draw down to zero power. Latest incident required a battery replacement instead of just a jump to restart.

After 4-5 years of usage, the bluetooth doesn't work any more. The Acura dealer said it costs more than $600 to be replaced with new one. I checked up the internet, and lots of Acura mdx owners have already acknowledged this problem and looking for a solution on the internet. Everyone has exactly same problem and it exactly happened 4 -5 years after purchase.

Not sure if this related to takata airbags. My wife was in bad rollover accident involving a 2009 Acura mdx on nov 5, 2015. At 5:15 pm on 11/5, thursday, it was dark and raining as she was heading east on us route 12 close to the arcelormittal usa office and slipped, veered off the road and SUV rolled over and cart wheeled and fell in a ditch. The SUV was upside down when I arrived after a first responder called me from the scene. Not sure why she veered off when she was on the left most lane. She suddenly crossed 2 lanes and shoulder and ended up in a ditch. She was not fatigued since it was less than 3 min since she left from the office and we have blue tooth handsfree in our 2009 Acura mdx tech. Not sure if the air bag went off falsely or if she had a tire burst. I know both front tire

Tl* the contact owns a 2009 Acura mdx. The contact stated that the rear automatic hatchback sensor failed. The hatchback closed on the contact's hands, resulting in injuries to the fingers. The contact believed the failure to be a safety hazard because the he was attempting to stop the hatchback from closing when it shut and slammed his fingers into the door. The vehicle was not inspected or repaired for the failure. The failure and current mileages were 26,000.

There must be a defect in my 2009 Acura mdx head restraint system. I believe it has resulted in or contributed to a neck injury . I have had neck pain bad enough to require four months of physical therapy and five surgical procedures. The head rest forces my neck and head into an unnatural forward position. The head rest only moves up and down and not forward and back. I am unable to adjust the seat and steering wheel to accommodate for the lack of adjustable in the head rest. *tr

My 2009 mdx with 3500+ miles has been taken to dealer 3 times in the last month. Once I had to get it towed to dealership. First time I was told that they was issue with poor quality timing belt pulley. So timing belt got shredded. They had to replace the both. They took almost week to replace it. With in a day, 2009 mdx developed issue. This time there was an issue with catalytic converter. They took another week to replace. Again with in two days, "check emission system" came up again. This time I was told they would have to replace another catalytic converter and also sub converters. I am really concerned about the quality this vehicle. *tr

2009 Acura mdx with less than 4000 miles developed an issue with timing belt pulleys, timing belt and front part of engine. *tr

Tl* the contact owned a 2009 Acura mdx. While driving 25 MPH, the check engine indicator flashed. The contact pulled the vehicle over to a shoulder lane and exited the vehicle prior to the engine compartment catching fire. The fire department extinguished the fire. A police report was filed. There were no injuries. The insurance company towed the vehicle to a storage area. The vehicle was destroyed. The local dealer was not contacted. The manufacturer was contacted and provided no additional assistance. The failure mileage was approximately 130,000.

Was told on today show (nbc) that could check to see if Acura air bags need to ne replaced even though not an official recall. Please let me know if these airbags are the ones that are to be replaced and if so, when. Many thanks.

I have a recurring problem with my air bag system on my 2009 Acura mdx (vehicle no [xxx]) which my local dealer has been unable to resolve. I first noticed the problem when the vehicle had approximately 21,000 miles. I contacted the service department at kearny mesa Acura and informed them the check air bag light was coming on. Kearny mesa Acura asked if it was on all of the time. I explained that the warning light was on intermittently (some days it was on and some days it was off). They said not to bring the car in until it is just on all of the time (everyday). Several months later it had degraded to the point where the light was on every day, so I brought the vehicle in for service. They tested the vehicle and replaced apart on the driver??s side airbag (part no 78055-stx-a10)

I brought the car into the dealer because I was having transmission problems or power steering problems. I indicated that the car makes a whine at about 1500 RPM. The dealer chose to treat it as a power steering problem. The power steering pump was replaced. There was still a whine although less. The car RPM hangs up on deceleration to a stop. Some times when going down hill the car does not upshift until the car is accelerated even though the road slope is zero. The dealer never informed me when I brought the vehicle in for the original concern that there were some problems with the transmission or torque converter hanging up. *tr

I took my 2009 mdx into Acura dealer for shudder at 35-45 MPH at 68k. Service tech wrote up repair order as PCM update. They did not document the shudder complaint. Even tho I drove with service tech and then he drove also, verifying shudder. I had to go back 2nd time as PCM didn't take according to dealer and that's why shuddering continued after 1st PCM update. Now at 107k, shudder is back. Mdx out of extended warranty by 2000 miles and Acura/Honda refuses goodwill repair. This is my second mdx. The torque converter needed replaced in my 2003 mdx. Acura assured me when I purchased the 2009 that this known problem was resolved. Obviously the torque converter/transmission continues to be faulty. I'm wondering if the PCM update is disguising the problem pushing the mdx past the mileage

Acura mdx (2009) vibration issues: since purchasing the vehicle new, there is a vibration driving at speeds exceeding 70 MPH. The vibration can be felt through the chasis and steering wheel. The dealer has replaced the tires, rims, drive shaft and performed multiple balancing and alignments. The manufacturer representative could not resolve the issue initially, but later suggested the replacement of the drive shaft. This worked initially but the problem has resurfaced again. I filed a lemon law claim that Acura has neglected to respond to fully. They tried to fix it, but the problem is still present and getting worse. When driving the car, it feels at times, as if the wheels are going to fall off. It is often worse when driving up hill when the car is cold and the weather cold. It

Tl*the contact owns a 2009 Acura mdx. While driving approximately 75 MPH the windshield wipers and the windshield wiper fluid engaged on its own and remained on. The vehicle was taken directly to an authorized dealer where the fuse to the windshield wipers were disconnected and the contact was told this was a known failure. The contact was then informed to take the vehicle to another authorized dealer because they did not have the parts needed to remedy the failure. The parts were not available. The failure and current mileages were 14,808.
