TT: During previous air conditioning service, leakage prevention agent (A/C stop leak) may have been added to the A/C system.

The gel substance that forms can cause the A/C compressor to bind and or seize.

H0Y Region Email2018-06-11. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; AIR BAGS; EQUIPMENT:ELECTRICAL. Region Email: The subject vehicles are voluntarily equipped with an event data recorder (EDR). The EDR only collects, stores, and allows retrieval of vehicle event data, including crash events. It does not control the operation of the vehicle or crash safety systems. Due to a software error in the air bag ECU where EDR data is stored, the EDR data for ?Frontal Airbag Deployment, Time to 1st Stage Deployment,? and ?Frontal Airbag Deployment Time to 2nd Stage Deployment,? will show the same value at the time an event is recorded. This software error has no effect on the actual air bag?s deployment times for both stages. Both air bags operate as designed.
