Default "04 GMC Yukon XL 2500 Speedometer problem

Vehicle is in the title...has a 6.0 in it and I just pulled and replaced the head on the passenger side to have a sparkplug thead fixed.....put all back together today and had to jump start it as the battery had drained while sitting for awhile...everything works fine except now the speedo reads over 120 mph no matter what speed I'm doing. It started at about 72 then held steady at about 85 and now is at 120. Actually it reads 120 shut off sitting in the driveway! Tried disconnecting the battery to reset everything and still in the same spot. All other gauges work fine, just the speedo has an issue.....Any thoughts or suggestions on what to try?

Thanks in advance.....

--------------------------------------------------------------------------------

THIS BULLETIN IS BEING REVISED TO INCLUDE CERTAIN 2005 MODEL YEAR VEHICLES IN THE U.S. ADDITIONALLY, FOR U.S. 2003-2005 MODEL YEAR VEHICLES, GM WILL PROVIDE THE INSTRUMENT PANEL CLUSTER (IPC) ONLY, AT NO CHARGE TO THE CUSTOMER FOR VERIFIED FAILURES BETWEEN 70,001 MILES (110,001 KM) AND 80,000 MILES (130,000 KM). ANY ADDITIONAL COSTS, INCLUDING LABOR TO REPLACE THE INSTRUMENT PANEL CLUSTER, WILL BE THE RESPONSIBILITY OF THE CUSTOMER. DEALERS WILL BE RESPONSIBLE FOR THE RETURN OF THE CUSTOMER'S IPC BACK TO THE ELECTRONIC SERVICE CENTER. PLEASE DISCARD ALL COPIES OF BULLETIN 07187B, ISSUED SEPTEMBER 2008..


--------------------------------------------------------------------------------

CUSTOMERS ARE BEING INSTRUCTED TO CONTACT THE DEALERSHIP TO ARRANGE AN APPOINTMENT IF THEY BELIEVE THEIR VEHICLE HAS THIS CONDITION. THE CUSTOMER IS BEING ASKED TO PROVIDE THE VIN SO THE IPC CAN BE ORDERED IN ADVANCE OF THE SCHEDULED APPOINTMENT. THIS WILL ELIMINATE THE NEED TO KEEP THE VEHICLE OVERNIGHT. DEALERS ARE TO OBTAIN THE VEHICLE MILEAGE WHEN SCHEDULING A SERVICE APPOINTMENT. THE VEHICLE MILEAGE WILL BE REQUIRED WHEN PLACING AN ORDER FOR THE IPC.

Condition
Some customers of all 2003-2004 model year and certain U.S. 2005 model year Cadillac Escalade, Escalade ESV, and Escalade EXT; Chevrolet Avalanche, Silverado, Suburban, and Tahoe; and GMC Sierra, Yukon, and Yukon XL vehicles have reported that one or more of the instrument panel (IP) cluster gauges stick, flutter, or become inoperative. This may cause inaccurate readings, including the speedometer and fuel gauge.

Special Coverage Adjustment
This special coverage covers the condition described above for a period of 7 years or 70,000 miles (110,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.

Dealers are to replace the instrument panel cluster after the condition has been verified. The repairs will be made at no charge to the customer.

For verified failures between 70,001 miles (110,001 km) and 80,000 miles (130,000 km) on U.S. vehicles, dealers are to provide the customer with an instrument panel cluster (IPC) only. Any additional costs, including labor to replace the instrument panel cluster, will be the responsibility of the customer. Dealers are responsible for the return of the customer's IPC back to the Electronic Service Center.

For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after September 28, 2007 for 2003-2004 model year vehicles, and March 23, 2009 for 2005 model year vehicles, 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 September 28, 2007 for 2003-2004 model year vehicles, or March 23, 2009 for 2005 model year vehicles, must be submitted to the Service Contract provider.
