Official summary
Owner Notification Letter - This warranty only covers vehicles that have a defective air conditioning condenser installed at the factory. The A/C condenser was not manufactured to specification. As a result, tiny holes may develop in the condenser tube walls that allow refrigerant to leak out. The warranty will not apply to any vehicle that has leaking condenser due to foreign object damage.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
