#1916 of 2052 07 MDX w/sport package - vibrations at 65 mph
Sep 20, 2010 (6:19 am)
2007 MDX starts vibrating at 65 mph, new set of tires didn't help. Definitely coming from the front, I assume it's the suspension and not the wheels. Acura service rep dismissed the problem by stating - Oh, we can't recreate the problem because we can't drive at that speed for fear of getting a ticket! And that's after dropping 1K for a new set of tires, at $45k a pop I'd expect a near damn perfection. Can't imagine a BMW dealer insulting his customer like this... Is this a safety issue? I understand most drivers of this car are soccer moms who only drive at that speed in the Nordstrom's parking lot, so they don't complain about this issue.

I had the same problem. After 3 dealerships and the run around, it turned out to be bad rotors. I ended up having to get corporate involved as none of the dealerships could find the problem and kept blowing me off.
The rotors they used on the 2007 are no longer being installed.

At what mileage did you have to replace the rotors and brakes? I have 45,000 of mostly highway miles now and was advised to consider replacing brakes and rotors.

I replaced mine at 50k but only to seriously upgrade system, not for regular maintenance. Used Hawk HPS pads and upgraded rotors. Night and day difference. Also replaced tires with Grand Touring M+S - dropping the truck tires that came on the MDX. Much better cornering and braking, especially in the wet. Works just fine in Snow, also.

"I have 45,000 of mostly highway miles now and was advised to consider replacing brakes and rotors. "
Brakes and rotors that were an inadequate design for this vehicle unfortunately. I replaced allthe way around between 40-50k miles at a cost of $1000.
BTW, the brakes on our '07 are light years ahead of the '04's

Battery problem?.... suggest anyone using a factory battery replace with a gel battery. Battery came with with MDX is a joke. I purchased a 07 MDX back in 06(November) and decided to take a long road trip(winter) from new york to Canada. having driven half way there i stopped on a rest stop to get some snooooze; engine turned off but left the radio on for like a hour or so. woke up and found the darn MDX couldn't start and realized the battery have just gone KAPUT. finally i was rescued by a good samaritan driving a MB AMG. i was like why you want to trade my car for your car? Enuf BS... after driving back to NY the battery would die everytime if i turned off the engine for 10 minutes or so with light or radio on. I had to flag other cars for jump start couple of times. after 5th or 6th times i decided to crash myself into auto parts store and get myself a gel battery. Ever since the is replaced, I have not have any problem with battery dying every so often even if i have the card turned off and/or lights on.
Clicking sound when steering either direction.... OH BOY I'm having this problem and is becoming ANNOYing! I've been to the service center complaining bout' the noise for at least 10 times. They have changed front CV joints and even replaced both rear structs(which I'm glad they did cuz if they don't they cost at least $1500 for one) and still the clicking noise is there. It is most noticeable on a stop and make turn gradually to either direction. Noise can be most noticeable during parking reversing into a spot. I just took my car back to the dealer and now they claim noise is coming from the front left struct. They are in progress ordering the part and should be in sometime this week. I'll let you all know if that kills the clicking sound.
P.S.: Sometimes I wonder if I should have just trade the car to a German Dealer and get myself a X6.

Did your dealer replace you a set of tires free of charge? I know one of my rim is slightly bent but i hessitate to shell out near $500 for a brand new one. Anyone in this forum awared if dealer will replace your rim(s) if still under warranty? Wheel vibrate at high speed on the highway.... aside from changing your tires.. you might want them to check your RIMs. One or more rim(s) bent might give you vibrating... not just wheels not being balanced.

"..clicking sound when turning either direction..."
What you seem to be describing is common to a 4WD system that uses a locked center differential which is inadvertently left engaged on a tractive surface. So that clicking sound CAN be the result of the SH-AWD system keeping the rear drive too tightly engaged during tight and/or low speed turns.
A R/awd system, base REAR drive vehicle, would NEVER have the front drive engaged while turning turning tightly, high lateral loads on the front wheels, But a F/awd system such as the SH-AWD system absolutely MUST keep the rear drive engaged while turning. Otherwise the combined stress on the front wheels' traction coefficient due to having to support drive torque, FULL drive torque, along with HIGH lateral forces might very well result in loss of traction altogether.
Pull the fuse(s) for the SH-AWD system while the ignition is off and see if the clicking sound remains.
The early MDX's with the VTM-4 F/awd system had premature transaxle failures for this very reason, both front and rear drive torque applied simultaneously simply resulted in to much stress, driveline windup and/or tire scrubbing, and that resulted in failure of the weakest link, the transaxles.

QUICK - have your torque converter checked before your warranty is up. I had exact problems, they told me to replace the original tires, new balance, new alignment ($2000). Fast forward 2 weeks - I drove a stick shift for many years & could feel the "tug & shake" of improper shifting ... had the technician go for a 40min drive with me ON HIGHWAY where the car could heat up & really experience its issues. The converter is being replaced & they told me that I'd have to replace 2 front brake routers on my own ... going to ask corporate to pay for that too ... after reading this blog.

Same! grinding right after speed bump... tried with brake, tried w/ gas, tried neutral - all the same. Have had my 07 T&E 48k into the shop more times than I'd like since Nov06 purchase. Had technician drive it over bumps, but he couldn't recreate. Put 4 new tires on balance, alignment ... one month later shuddering, gears seem off, smells funny ... they are replacing my torque converter and hopefully, full transmission. I've also had trouble with one of the doors unlocking, the battery dying very quickly when engine is off / radio on, and the back seat getting "stuck" in the down position. Bought Acura for its reliability, but definitely questioning my purchase.
