#74 of 128 Harmonic Drone solved (for now anyway) by jringo

Oct 11, 2008 (9:49 pm)

I have a 2006 Honda Accord Hybrid purchased brand new.
Love the car. At only 2000 miles, and ONLY in cold temperatures around 30 degrees, the car would sometimes run rough, idle rough and emit a roaring sound.
Honda replaced FP number 38700-SDR-AO5 ACM Unit,
(according to my warranty copy report.)
That solved it for me. Over 30,000 trouble free miles since.
I asked the "clueless" service advisor twice what the replaced part was, and he said he had no idea! Forget the service manager. Every time I tried to speak to him,
they told me he was "out." $30,000 for a car, and they don't want to see or hear from you. Do you believe this arrogance? Anyway, that's my experience.
If anyone knows what part that is, I'd like to hear from you what it is.
Thanks

April of 2009 I purchased a 2005 Honda Accord Hybrid at my local Honda Dealer, including the Honda Care extended warranty to 97,000 miles. The car is in perfect condition with only 37,000 miles on the odometer. It runs and drives like a dream, and is getting over 28 mpg average on every tank. My only problem is the DRONE when in eco mode at around 50 to 65 mph. This normally happens while driving in cruise control. I see others have had similar problems and I will take that information to the dealer.
The last entry on the forum was Oct 11, 2008. I was wondering if anyone else has more information on this problem.

to the newer posters, look back into the 60's posts on this problem. I bought the car new and it developed the drone after year 2. I was very frustrated and lost some money having the service department repeatedly search for the phantom sound that only one person agreed they heard- but had no information on. I was accused of hearing things and also had some serious gender discrimination lobbed my way- apparently being a woman I just didn't understand my car. I researched it myself and found a TSB-05-006 reference but was unable to pull up the report. the service person I gave it to did find it and ordered the part- #06390-sdr-307 "noise kit" that finally solved the problem. Honda did not issue any service report for whatever their reasons, leaving the service depts. either unable or unwilling to address it. I hope this helps.

Thanks for your reply, and there is no question about the drone being real. I called my dealer with the TSB number and described the noise, he did say he was not aware of any problem like that, but that he would check out the TSB and get back to me. Within a week I got a call, he said he had the parts and was ready to make me an appointment to have it fixed at no cost. Well, since the repair, which involved replacing both front speakers and a module under the dash, I have not heard any noise since and what a wonderful feeling that is.

great!
 
though we have been vidicated and relieved of the "drone," the only justice here is that the service was not charged to us. Otherwise I still feel Honda has gotten the better part of this deal by not issuing a report and taking responsibility. Though I will soon be in the market for a new car (89,000 miles since 2005,) I am annoyed enough to look elsewhere first. (My service center is absolved of any guilt here- except the guy who believed the imaginary sound was a woman thing)

I bought my son's 2005 Accord Hybrid last year and began noticing the "drone" in a few months. Now in the summer it is unbearable! through the forum, I found out what it is, downloaded the Service bulletin and took it to the dealer. Luckily, they were able to hear it on a test drive. Estimate to fix $650! It's out of warranty- 46,000 and I just spent $400 for a new wiper motor. What was your mileage? Should I take it to general mechanic? Can't afford this fix, but can't stand to drive the car!

I really don't remember the mileage, but since my complaints had already been on record since the second year, it was probably less or similar mileage to your car. I also had the extended warranty from the date of purchase, which you may not have since it is a used car. I might fight harder with Honda- try reaching out to the regional manager- it didn't help me beyond getting the service people to call me in, but it was before I found out about the service bulletin- that made the difference in the end- and the newly hired service person who took me seriously. Honestly, I really do love this car and so far only Honda has done all the service maintenance. Probably could save money elsewhere, but since it was one of the first hybrids out there and most mechanics didn't know much about them at the time, I figured if Honda broke it they'd be responsible to fix it. I'm close to 90,000 miles and other than normal maintenance, a new battery and tires, no other repairs. The annual maintenance at Honda costs plenty, $200-500, depending on mileage, but I'm sorry they discontinued the car. I even looked for another when my son needed a car, but there weren't any used for sale. If your car is anything like mine, you have plenty of miles to go, and the "drone" will drive you crazy- so I'd make a big stink to Honda regional first, but eventually I'd get it fixed.

Hi Jayngee,
Did you have any luck fixing your HAH? My '05 HAH has been making the similiar noise and when i brought it into the dealship the quoted me $650 to fix it as well and it's out of warranty. They told me I need a new Active Noise cancellation system put in. Did you find out if a local mechanic can fix something like this or if i should have the Honda dealership do it. I was hoping there was a recall on this issue since it's a huge known problem but I haven't found anything yet. Just curious what you did. My car is still at the dealership as I wanted to do research before I have them fix it since I can't really afford this either!!

as I noted earlier, I've only had Honda service work on my car. because it was one of the first hybrids out at the time, I thought it was safer to have someone trained on the car do the work. Even though hybrids are all over now and a local service guy may be perfectly capable of doing it, I have no advice for you. I've owned used cars before, and big money repairs are always a possibilty. If you've tried going up to honda regional to appeal for a break, and don't get one, you're just going to have to find a qualified person and pay them. I would never tell you to keep driving with the drone- it just got louder.
