Known Problems

The AC compressor may fail causing the AC system to blow warm air, smoke may also appear from the engine. A failed AC compressor will require replacement. Mazda has extended the warranty on these compressors to 5 year or 60K mikes. If these conditions are noted our technicians recommend to turn the AC system off and have it inspected as soon as possible.

Model years 2007-2012 of the Mazda CX-7 using the 6-speed automatic transmission have been known to produce hard shifting and transmission slippage between gears. This is most noticeable when the transmission is hot, but can happen at any time. Note, this transmission is designed to be ‘sealed for life’ meaning the transmission fluid is never meant to be changed.

As many drivers and owners have learned, the issues are caused by problematic software for the transmission or mechanical failures associated with the transmission valve body or shift solenoids.

In order to restore transmission performance while shifting, the manufacturer of the transmission has issued several software updates that should correct the shifting issues. If hard shifts and slippage still exist after the software updates are completed, the transmission must be removed, disassembled, inspected and repaired.

Some technicians have advised replacing transmission fluid at normal intervals, but the manufacturer guidance is to use the original transmission fluid for the entire service life of the vehicle. 

 

The engine may develop a ticking noise from the front of the engine due to a worn timing chain. Our technicians tell us that replacing the timing chain and related component will generally correct this issue.

A lack of power may develop due to a failed turbocharger. Failed turbochargers will require replacement to restore engine power.

A chirping or squeaking noise may be noted from the front of the vehicle when traversing bumps at low speeds. Our technicians tell us this type of noise is generally caused by the front strut mounts which will require replacement.

The Check Engine Light may illuminate with a stored code P2006. This is most often caused by a sticking intake manifold runner control (IMRC) valve. Our technicians tell us that depending on your vehicle the valve may require replacement and/or the powertrain control module (PCM) software will require upgrading.

A vibration may be noted upon brake apply. The is commonly caused by warping of the front brake rotors. Our technicians recommend that warped rotors be replaced to correct this concern.

The automatic head lights may be to sensitive or not sensitive enough depending on the setting. The appears to be a design characteristic of this model.
