Did anyone else get that letter?
"This letter is intended to make you aware that some 2009 model year GMC Yukon vehicles, equipped with a V8 engine, may have a condition where the throttle position sensor may cause the engine to run rough and cause the malfunction indicator lamp and/or an Engine Reduced Power message to illuminate. If this occurs, it could result in reduced engine power.
Do not take your vehicle to your GMC dealer as a result of this letter unless you believe that your vehicle has the condition as described above."
I think i had this as I was accelerating uphill on a highway... ended up going <20mph uphill being honked at and passed by hundreds of cars and I had the reduced power message
