Sudden loss of power by model year
What owners say
The radio and navigation intermittently go on and off while driving.my ABS,check emission system,shaw-d will go off. Car will shut down while im driving and I lose all power. I lose power to locks, windows and back hatch. Some days when starting the car it wont turn over and start up. Somedays after driving and I turn the car off, I lose all power. While driving the car will jump into gear as I am accelerating.
While driving, the car will frequently lose electrical power. Dash indicator lights come on, the radio shuts off and sometime I'll have to reset the radio and navigation codes. While at a stop light, sometimes depressing the gas pedal does nothing and then suddenly it will begin to move. I'm very concern the unpredictable nature of the problem will cause a wreck if I lose engine power, especially in a curve.
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.
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.
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!
Engine shut off while driving approx. 35 MPH, resulting in total loss of power steering and brakes and electrical systems.. Pulled over and brought car to a stop. Was in the process of getting out to check engine when interior lights came on, restarted engine and commenced to drive approx. A mile when it all repeated. Got car home and called for tow truck to take car to acura dealership where I had purchased 1 month previously.
Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6) 2007 acura mdx 34,000 predominantly highway miles friday evening, as I was pulling out of a car wash, I heard a clunk, the instrument panel lit up with a "check charging system alarm" and I had no power steering. I immediately stopped and found a belt pulley (later identified by acura as a "crank pulley) laying in the road just behind the car. I opened the hood and the serpentine belt was not turning, explaining the loss of power steering. Upon investigation, the dealership explained that the outer rim of the pulley is compression fit onto the hub and that the pulley came apart at this compression fit. The hub remained connected to the crank, but without the hub there is no tension provided to the serpentine belt and, hence no power steering (or alternator or A/C for that matter). The local acura dealership provided a simple repair replacing the pulley, but could not explain why it failed. I contacted acura's regional case manager [xxx] and asked for a case number [xxx] )to receive feedback from an analysis of the failed part. Why did it fail (root cause) and what should be done to prevent future occurrences? [xxx] replied "that is not going to happen", "I'm closing out this case". I am very concerned about the root cause of this failure. Had my wife or daughter or other weaker person been driving in a more critical situation, losing the power steering while moving could have been a tragic event. The car carrier driver told me that he picked up an mdx with a missing belt pulley just last week. I understand that he is not the authoritative source, but its is enough to increase my level of concern.
