I bought this car on mother's day 2017. During the following month I had the check engine light on non-stop, I started receiving error codes, then on the way to the airport (one the interstate), the car literally turned off. We rolled to the airport with no electrical system at all, then the car finally died, thank goodness we got out because for a few minutes we were locked in the car! We replaced the alternator, the battery, 3 of the 4 (o2) oxygen sensors, now the transmission light, the check engine light and the check starting system light are on. Today, the car didn't start twice and I honestly felt at risk just trying to drive home today. So all this has been from mother's day 2017 to now! September 20, 2018. The lights and codes don't stop on this car!
2007 Acura MDX electrical complaints
Page 2 of 3: complaints 11 to 40 of 51, newest first, as owners wrote them.
My 07 acura mdx has been experiencing intermittent resets while driving. Navigation and radio turn off and on and the vehicle does not accelerate when gas pedal is pressed.
While driving some lights in panel start lighting up, GPS turns off, engine running but wont accelerate and after few seconds will go back to normal. Took to acura they ran diagnostictest but can't find no issue. This is life threatening. Need acura to act on this.
Tl* the contact owns a 2007 acura mdx. On several occasions, while the contact's girlfriend was driving, the vehicle inadvertently stalled. There were no warning indicators illuminated. The vehicle was taken to columbia acura inc. (10979 montgomery rd, cincinnati, oh 45249 (513) 530-0100), but no diagnostic failure codes were found and the failure could not be replicated. The vehicle was then taken to superior acura (5555 dixie hwy, fairfield, oh 45014 (513) 829-8500) where it was diagnosed that the battery cables needed to be replaced. The vehicle was repaired, but the failure recurred. The manufacturer was notified of the failure and confirmed that no recalls were associated with the failure. The approximate failure mileage was 100,000.
Just like the other complaints the car shuts off without warning while in drive causing loss of steering and braking. Acura has offered little help with the issue. Very unsafe and deserved of a recall.
The vehicle will randomly shut off and restart while in motion at various speeds whether on the highway or surface streets. There does not appear to be any rhyme or reason as to why.
Tl* the contact owns a 2007 acura mdx. While driving approximately 45 MPH, the GPS and instrument panel lighting ceased without warning. When the contact depressed the brake pedal, the lights illuminated. The vehicle was taken to an independent mechanic who diagnosed that the alternator needed to be replaced. The vehicle was repaired; however, the failure recurred two days later. The manufacturer was not notified of the failure. The approximate failure mileage was 103,500. The VIN was not provided.
Had a big rain storm the other day. Got into my car after it being parked at work all day and found it was leaking from "c" pillar. Turns out, sunroof decided to flip up on its own during the day with the car parked and off. Took car to my local shop who has been familiar with acura electrical problems. I told him to disconnect the wires to the sunroof function completely. I dont need to use the sunroof or have it decide to open on its own again. This problem could have caused even more serious electrical problems, but luckily water did not penetrate to the other electrical systems. This is the third major electrical problem I have had with this vehicle. There are serious electrical problems with the mdx and acrua/honda refuses to issue any recall or even address the problems, which are prominent in this vehicle
Came out to a dead battery after replacing battery just a few months earlier. After already going through the electrical problem of the defective blue tooth, knew it was another electrical problem. Took car to my local shop where he diagnosed another electrical problem, this time with the air conditioner relay/compressor switch. I do not want to be without air conditioning, so had them fix the problem. This is the second electrical problem with the 10 year old mdx with only 90,000 miles. This vehicle has serious electrical problems and they are being ignored by honda motors. I have read many instances online of people who had this same vehicle and the cars have caught on fire from these various electrical problems
Battery kept draining and was dead on a few occasions. I came out to a dead battery on two occassions and then decided to take car to electrical repair shop. Problem was with the bluetooth. This is a widely reported problem with this vehicle. Electrical shop disconnected bluetooth. Honda is aware of this problem yet does nothing about it in form of recall.
Acura mdx 2007, vehicle engine and electrical system stopped while car is motion on freeway on my way to work on january 24, 2017 about 6:35 am on 610 loop passed the stella link exit. I had to merge over to the edge of fwy to restart the car. The dash board lights and car turned off completely while in driving mode, going about 60 MPH. Very scary and unusual. This is a life treating incident and needs an immediate recall. There are numerous online complaints about this issue, so why isn't there a recall. Are they waiting for someone to get fatally injured or worst? This problem demands immediate attention!
The hands free link unit has an issue where it stops working and drains the battery of the car. I've gone through 3 batteries in the last 6 months and when I finally disconnected the hfl unit, the car has been working properly.
Having issues with the drainage of battery. Three in one year. The culprit was the hands free link and xm radio. The bluetooth features in this car has caused it to shutdown completely several times or not start up. After searching online, this has been the complaint by thousands of other acura mdx 2007. This is dangerous and may cause car accidents. This is too common an issue to not recall these parts.
Battery keeps dying even after buying a new one. It happends even after being parked just for a few hours one day the car stopped completetly and suddently while driving
This is the third time the electrical system has failed caused by "battery drainage". Local repair shops do not know how to fix problems, but dealer's and honda mechanics are very familiar with this horrible problem. Everyone fixing the problem knows very well this should be "a recall" matter, and creates a great road hazard as well are garage fires and loss of life. The things involved are "blue tooth" modular, air conditioner clutch relay, fuses. Regarding the blue tooth, this modular gets very very hot, and could cause a fire!! When the battery fails to charge while driving to get safely off the highway is very dangerous, much worst at darkness!! Honda needs to get their act together and recall and fix these problems now. My experience happened with the car in motion, and all indicators flashing, rear axle noises, heat inside car, loss of power, and vehicle in "kind of, a limping mode". Very scary and dangerous occurrence. We are the original owner of the car, now with 140,000 miles, and always serviced every 3-5,000 miles. We have taken pride in this vehicle, until this "battery drainage" problem, now is effecting our thoughts about honda motors.
My 2007 acura mdx dies almost everyday battery drainage. Replace the hfl module as well as the AC relay. Yet battery still drains almost everyday and have to jump start it just to leave for work.
Battery keeps draining due to hfl module. Replaced battery and still keeps on draining. Hfl unit hot enough to melt plastic and possible fire hazard. This issue has been reported by hundreds if not thousands of mdx drivers and acura says they never heard about it. Yea right! For the price of the vehicle that we all pay for we expect great results. Acura you need to recall and replace the hfl modules before this causes a car fire and possible house fire.
Tl* the contact owns a 2007 acura mdx. Each morning when the contact attempted to start the vehicle, it would fail to start. The vehicle was taken to an independent mechanic where the cause of the failure could not be diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 120,000.
I purchased a 07 acura mdx 1 month ago with 115,500 miles and got the extended power train warranty. Hall nissan pulled the vehicle off hall acura's lot. They printed out a receipt from all the work acura did before I bought the car, and ensured me nothing was wrong with it that it went through a 150 point inspection. I took it to acura 2.5 weeks after I bought it because the check engine light came on and a tranny code popped up. They diagnosed the car and found $7,000 worth of malfunctioning equipment. Transmission range sensor, both front struts, AC coil and magnetic clutch, front cv axle boot leaking, rear shocks, rear sway bar bushings, transmission cooler hose leaking. I have spoken with numerous managers about this, they wont replace the cv axel assembly (suggested fix), the transmission cooler line (suggested fix), or front struts or back shocks which failed upon inspection. They are telling my warranty wont cover it because I haven't owned the vehicle for 60 days. They need to fix this. They should not have sold me a car telling me everything is ok and when I take it back to the same acura service shop that did the original inspection 2 weeks later there is now $7,000 worth of damage. There is a few things wrong with it that was said was fixed on the original work order that they never did. When I go over bumps the suspension makes a clunk from the front. After researching online many people have the same issue.
Several times, the electrical system shuts off while driving. I was lucky to be in the neighborhood and not on a highway. The dealer stated there is a problem with the bluetooth and we have had it replaced. This is the second time this has occured. The first time it happened, the bluetooth was under acura warranty. It was explained to me that the bluetooth is drawing energy constantly and the dealer suggested we disconnect it to avoid the same issue happening again. But that is the reason I had bought the car in 2007. It had integrated bluetooth. The times the car off while driving luckily was at a traffic light and in our neighborhood. I just hope it does not happen while we are on the highway. Acura also stated that maybe the wiring to the battery was stretched and I had to pay to replace it. I have never had to replace that wire. I believe the bluetooth and its controls are a defective design but acura does not want to admit it.
Related to hands free link which hasn't work in two years. I have replaced the battery several times (once twice one week, under warranty). I replaced the battery a week ago and ask them to please reset hands free link (a request I make every time the car is serviced) and my car nav flickers now. Two day ago the car momentarily lost power while I was driving in town!!!!!!! I was fortunate to be on street with 35mph speed limit and no other cars. It was terrifying.
Constantly having electrical problems. We went on a vacation and came back to find the battery completely dead. Took it in and they diagnosed the problem as a bad hands free unit which was replaced. Now we are having all kinds of electrical problems. Each time we turn the car on the auto setting toggle between driver 1 and driver 2 settings. Occasionally you hear a pop on the speakers when you start the engine. Now we have the check airbag system light come on and won't go off. This car has been a money pit with electrical problems that nobody seems to be able to diagnose. We have spent over $1000 trying to figure it out with no luck.
1.today when I went outside to start my 2007 mdx, the "check starter system" lit up. I waited about 30 seconds and tried again, my vehicle started up. Got to work 1 hour later, turned car off and back on without issue. Hoping it starts after work. This problem just seemed to happen out of no where. My battery is fine but did have problems about 8 months ago where I ended up have to pay approximately $300 to have battery cables/connector replaced by the acura dealership. The fuse in the cable or connector went bad.
Driver noticed smoke coming from engine area while driving, electrical systems started shutting down. Driver was able to pull to side of road, within 1 minute engine was in flames.
Car constantly loses power or get warning light stating I need to check my starting system. Have replaced the battery 3 times this year, replaced the alternator twice and have replaced the starter once. Sometimes car does not lose power all the way, but will lose functionality of windows, turn signals, windshield wipers, radio, AC and any other function although car will still drive. Inside the arm rest is usually extremely hot when this happens. So hot that it burns your hand to the touch. After reading over 20 complaints on this same type of issue, it seems to be caused by the handsfree link in the car, which I have not been able to use because it stopped working completely back in march 2014. This issue needs to be recalled before someone is seriously injured or worse!
Tl* the contact owns a 2007 acura mdx. The contact stated that the vehicle failed to start. The terminal battery was replaced on several occasions, but the failure recurred. The vehicle was towed to an independent mechanic who was unable to diagnose the failure. The vehicle was taken to the dealer who diagnosed that the wiring harness needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 93,000.
Battery in our 2007 acura mdx has had to be replaced 3 times in the past couple of months! Turns out that the handsfree link module was draining the battery and causing it having to be replaced numerous times. This could cause a fire which can pose as a deadly result especially if the car is parked inside of a garage. This needs to be replaced by acura free of charge asap! I disconnected it rather than replacing it after reading the numerous complaints on this matter!

Came out to our 2007 mdx in the morning and found that the battery was completely dead for third time in a week. Charged battery again and drove the car to dealership. Problem diagnosed as an open circuit in the hands free unit even when ignition is off. Replaced the hands free unit. Approximately 60 days later, same problem again, and new hands free unit again the problem. The unit is located in the console between front seats was very hot and could have caused a fire. Dealership informed me that they had seen this problem a lot, but that there is no recall and acura has no answers for them. Had to replace battery after 2nd unit failed, now working on 3rd hands free unit in less than one year. After 2nd incident I contacted acura and reported the problem and they stated that they were unaware of any problems with these hands free units. Apparently, acura does not yet have the ability to access the internet as a considerable number of other 2007 mdx owners have voiced the same concern in the acura owners forum after experiencing failures of their hands free units. Obviously, the hands free unit manufactured by johnson controls has a design defect which is causing this problem and creating a fire risk in the passenger cabin even when ignition is off. Defect could also cause house fire if car is parked in an attached garage due to the fact that the circuit is open even when the ignition is off and gets very hot to the touch. This problem needs to be investigated by n.h.t.s.a., as it is a significant fire safety risk. I encourage all parties who have experienced a similar problem to file a complaint here so that the scope of the problem can be better determined and acura will be forced to take this problem seriously.
