Coverage
Adjustment

On some 2015-2017 model year Cadillac Escalade, Escalade ESV, Chevrolet Suburban, Tahoe, GMC
Yukon and Yukon XL vehicles, may have a condition where thermal cycling on the combination
transmission fluid/oil and AC condenser cooler creates a crack that may allow refrigerant to escape.
This condition consequently may deactivate the AC system which may cause potential customer
annoyance.
This special coverage covers the condition described above for a period of 5 years or 60,000 miles
(100,000 km) for Chevrolet Suburban, Tahoe, GMC Yukon and Yukon XL and 6 years or 72,000 miles
(116,000 km) for Cadillac Escalade and Escalade ESV, whichever occurs first, from the date the vehicle
was originally placed in service, regardless of ownership.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after
October 6, 2017, are covered by this special coverage and must be submitted using the labor operation
codes provided with this bulletin. Claims with repair orders prior to October 6, 2017, must be submitted
to the Service Contract provider.

procedures specified below. The conditional right to reimbursement is provided by GM solely in the
interest of customer satisfaction and is personal to Customers. Customers may not assign and GM
does not consent to any assignment of any Customer’s right to submit reimbursement claims, or to
receive reimbursement, or any other rights granted by this Special Coverage to any third party,
