[ASH8]

This applies to cars with FULL Automatic AC (Air Conditioning) Only.



Mazda has released a bulletin to all Mazda Dealers informing them of an issue with owners complaining of poor AC performance which has actually been around for sometime on multiple models over many years.



The small external Sensor located behind Front Bumper can be out by as much as 50 degrees Fahrenheit or 10 degrees Celsius (under reading) meaning Temperatures outside of car are physically way hotter than what the instrument reading (from Sensor) says it is resulting in the cars AC's not cooling down inside cabin as it should.

Personally I know many owners who have had issues with Mazda's poor AC performance over many models, I trust this finally fixes the problem.

The supplier of the Sensor part to Mazda has rectified the issue with their parts manufacturing process.

In almost all cases if Sensor is determined to be defective the Front Bumper must be removed to access and renew Sensor, also depending on the car specifications the Radar and Cruise Control Sensors etc may require Dealer to re-aim them, We suggest Dealer has adequate NEW Sensors in parts stock so rectification can be performed on the same day.

Note: Not All cars with this sensor has defective Temp Sensor units, only those found to be incorrectly reading outside ambient temperatures will be renewed while still under normal new car warranty.
Personally I don't see too many CX-60's having defective Sensors (not all of them are).

This is Not a Recall.

Normal Warranty Period Applies.

Interesting, could this also be the root cause for the pore performance of the CX-60 EV range? The car gradually increases the buffer capacity on the battery as the temperature goes down. If the system input, is 10c lover than the reel ambient temperature, this will significantly lower the EV range performance of the car. ??

In the document it says the dash display also shows a lower temperature so I think we'd see the error if that was causing it.

One thing I did notice was that on the dash the battery temp on mine barely moves up the gauge when it's cold. I'm assuming there's no heat for it and that's probably why there's so much protection at low temperatures.

you are properly right, but it could be that the same sensor type is is also used in other applications..
