I am loving my first Acura but my 2014 MDX is giving me problems in two specific areas and wanted to see if anyone else is also having the issues.

1) Rear A/C - My poor 4 y/o and wife when on our first road trip kept complaining that it was hot in the back. I had it set to 70 or 72 up front set to sync all to the same temp. In the front the air was cold but the back was warm. I had to lower the temp in the rear to 67 before it started spitting out hot air. I took it in once and they say they fixed it but not true. I had to turn off the rear AC to keep the cabin temperature cool/even.

2) Vibrating front driver side when accelerating. Sounds like it vibrates when changing gears. I have noticed it at about 20, 30 & 40 miles per hour. Its only on the left side and happens more when warmed up.

I have scheduled another trip back to dealership to fix. It's still a wonderful car and when i drive my work car (2010 VW CC) I definitely miss the MDX.

 

The AC is probably a faulty thermostat. I wonder if the vibration, (we've heard that before) could be related to the present recall for loose powertrain bolts.

 

So got my car back today. They told me that the loud noise was due to the cover in the front of the car vibrating. They put some felt in the clips i believe. After driving the car all day i still feel the vibrations just not the loud noise so I may put it back. I don't hear the loud sound but it doesn't feel right. The loaner 2014 MDX drove much smoother but it was just front wheel drive.

The dealer was telling me that the sync button only syncs the front two seats temp which i think is BS. I need to do more testing because having a sync button when set at 72 with the front blowing out cold and the back hot air. Why would there be such a big difference in the temperature setting in the front and back of the car? Do you all have to set the rear temp 4 degrees less than front to be in sync with the temp of the air coming out? The more i think about it I should have left the car in the shop.

 

Front Struts or Dampers from the description of your symptom. Separated radial and/or bent wheel

The dashboard needs to be removed and replacement of the heater core will be necessary. The 360 degree seal around that most likely was rolled during assembly of the vehicle

 

Just curious....does the vibration sound kind of sound like a buzzing sound? I have that issue recently on my 14 model and it sounds like from the drive side front as well.

For some reason it started to happen AFTER when I kind of took off roading...when I said "kind of" meaning the road have small peddles and rocks.
