general problems of the 2003 GMC Yukon

My 03 Yukon denali is experiencing all of the same things that the recall on the 2021 Yukon is experiencing. What do I do? the recall notice I am referring to is n252494000.

About a month a ago my 2003 Yukon xl all of a sudden would not drive over15 miles an hr in rush hour traffic. I took the truck to the shop to have diagnostics ran. I was told it was the battery. The truck ran for about a month then all of a sudden the battery was back dead. Returned the truck back to the shop another battery was put in. It's been about another month. This time I was driving from miami to jacksonville and the truck lost power 100 miles outside jacksonville on I-95 north. It had all power just would not crank. Had it towed to the shop now I'm being to there's a problem with electrical.

There is an error message that displays on the dash for myself and thousands of others who own GMC/chevy trucks with these motors. They have a defective throttle position sensor with the truck where it says "reduced engine power". I've found 2 technical service bulletins that somewhat address the issue, but many people take their trucks to mechanics and dealerships to get the issue fixed and spend thousands of dollars in repairs and troubleshooting to get the issue resolved, to no avail. The 2 technical service bulletins that I found were #pip3089b (dated 10/31/2006) and #pip3042a (dated 8/30/2004). I've seen on many many forum posts about this issue and possible fixes, which when I read deeper into them, seem to not be true fixes.

Engine went into reduced engine power (rep) mode and 4 diagnostic troubleshooting codes (dtc¿s) were set all relating to the throttle activation circuit (tac). When this happens the engine power is shut off immediately and the engine will only idle. This is a known issue with gm and is a potentially extremely dangerous safety issue. The entire tac system ( throttle body, tac module, pcm, wire harnesses/connectors) needs to be investigated.
