If this happens only once after starting, it's very likely the ABS self-diagnostic. About 50 feet after you start rolling, the anti-lock brakes valves activate one at a time to verify they're working.
Unless someone else wants to chime in.
Thanks for posting this information -- I thought I had gotten a lemon. I just bought my 2008 MDX and have had the same problem with the rear suspension. I don't really hear it much over small bumps, but when I drive over potholes and go up or down driveways, the clunking noise is horrendous. That is unacceptable for a luxury SUV, especially considering that the problem has been around since the '07 model year. I hope that the dealership can fix the problem when I go in tomorrow. Thanks to you, they can't say, "we can't replicate the problem..."
I have the same problem with my car and after reading this forum, I found info on the 07-033 TSB. I was going to bring the car in tomorrow to see if the dealer can fix the problem per the TSB, but you are saying that the problem wasn't fixed? I'll let you know how it goes with my service -- stay tuned.
If anyone happens to know, I would be very appreciative of information one way or the other.
Any update on whether you got your issue fixed? I just bouhght an 08 MDX Sport and have the same noise from rear suspension. Dealer replaced rear shocks, sound went away for a day or so and is now back - very interested in hearing what your issue was and if it was resolved. Also, have you noticed the noise changing with additional weight in the car e.g. more noise with 4 people in the car than just one person?
Thanks.
I am planning to buy MDX 2004 w/50K mileage form the local dealer (not acura, eg. Toyota). The question is, am I qualified to buy an acura care extended warranty plan after my purchase? If the answer is yes, then, is this warranty will cover my MDX in USA and Canada? Because certified acura vehicles are covered in entire North America........
Your thought will appreciated.
Thank you

Just bought a base '08 MDX (after eyeing one and constantly thinking about for over a year) a couple of weeks ago and I try to "hypermile" whenever I can.
It seems that when I am coasting to a light, the car seems to have a "dragging" feeling (like brakes are being applied) when I am coasting down to around 40mph. It seems to happen again around 20mph.
Am I just being paranoid or is this normal from the automatic transmission?
Any comfort/advice is appreciated
As it turned out, one dealer told me they replaced the rotors. They lied. They resurfaced them. All other dealers went off the assumption the rotors were new.
What happened was the resurfacing was not done properly, which was causing the shaking. The fix: brand new brakes and rotors on the car.
You should contact Acura Client Care (I think it's in your owners manual) and tell them the problem. They will get you in touch with the right people. For me, they even contacted the dealership they felt was the best and made all the arrangements. I got excellent care and the car was finally fixed.
My transmission has been very good from new up to 117k miles when 3rd gear went. Acura dealer said save money and go to AAMCO so I took it to a local AAMCO dealer who identified internal problem. The took apart and found third gear bad. replaced third gear clutch plates and the piston. Replaced a pressure valve and re assembled with typical rebuild kit and a rebuilt torque converter. Cost me 2700.00. Right away I noted hard shifting etc but opted to hold off since I had to take it back for 10day check up. But within a couple of days i noted the tach jumping 100 rpms and then a loud vibration noise that sounded like going over grate in the road. This showed up when the tack was jumping but only some of the time.
Well long and the short I took it back to them 6 times and they rebuilt it 2 additional times and replaced the linear solenoids and the torque converter lock up solenoid at additional Charge on other visits, Now up over 3400. They even had me take it to acura to have them put on diagnostic computer and they even paid the bill.
Acura said a bad valve or the torque converter. On the last rebuilt the AAMCO tech found the torque converter lock up valve was sticking a little so he honed it. Got car back and noted tach still jumping but no sound. But a few days later the sound showed up again but very faint.
AAMCO is trying to tell me it is engine problem eventhough Acura ruled that out.
I am now going through Credit Card charge dispute process in an attempt to get my money back. Dont believe they should get unlimited attempts to fix the problem that I believe they caused by initial faulty repair.
Anyhow the problem I have occurres like this.
Cold start up, drive for about 10min, house to freeway. Get on I-4 and head to work and the tach starts the jumping within a few min. and the noise is there but faint. It usualy goes away after about 5-10 miles of travel. However since it was cold this AM 65 degrees (cold to me in FL) it lasted the whole trip. Usualy the pulsing goes away after all castings are good and hot and possibly since ambient temp was lower than it has been the problem presisted until I got to work, about a 16 mile drive.
Second time fix for audio lights illuminating delay after start up at night.
First time they replaced radio unit in april 08 and it happened again 1 month after and again 5months later and I finally got it on video from a phone! 2nd repair I go to pic up vehicle and rear passenger floor and seat is saturated with water and moisture. I visually inspected the area to find water in the door panel and grill of the door for speaker but the surface had been all wiped down! Something I do not need right now, I am so p-off and stuck on what to do and what to expect.
I refused to take the car so they could address the problem and they initially made excuses to what happened.
At what mileage did the vibration begin?
Please post the results and details of your repair.
Don't waste your money again on fuel system flushes. Just a cash cow for service departments. If you actually had a dirty injector a flush wouldn't clean it out anyway. You need high super high pressure.If the code faults an injector you'll need to replace it. Retrieve code and start from square 1.
I just wonder if I can have a routine engine oil/transmission fluid service on my MDX at a honda dealership. The nearest Acura dealership is 130 miles away, but I have a honda dealership near by. If I have the maintainence done at a honda dealerhsip, will this negatively impact the standard 4-year waranty? Thank you very much for your answer.
TQ
Page 35 of your warranty manual specifies that you don't have to have your vehicle serviced at an Acura dealer.
