The reporting timeline
When reports arrived.
Reports by year filed, not by the year a problem occurred. Showing the latest 15 years with reports.
55,000 miles is the median among 37 reports with usable mileage. The middle half spans 21,000–90,000 miles.
This describes the submitted reports. It does not predict when a vehicle will fail.
02 / Official safety campaigns
0 recall campaigns on file.
A campaign can cover only certain production dates or configurations. The count does not tell you whether an individual car has an open recall.
03 / The manufacturer’s record

Dealer message - Today, November 8, 2016 Acura is announcing four warranty extensions for model years 2007-2013 Acura MDX and model years 2010-2012 Acura ZDX vehicles to address Active Damper System(ADS) dampers from failures in cold regions. Basic Problem Dampers with ADS use metal particles in the damper oil to control movement/recoil. In cold temperatures the oil inside the dampers has reduced viscosity and a gap is generated between the main seal and the rod guide. The iron particulates in the ADS oil are then deposited in this gap blocking the path of the moving oil which damages the seal resulting in an oil leak. Cavitation occurs once enough oil is lost and the damper cannot keep up with operation of wheel up and down movement.
