It is just like the the service bulletin out for the 2006 and later gmc sierra except it’s for a 2004 gmc Yukon slt 4x4 4.8L. It is going into reduced engine power mode and it has to do with the throttle actuator control module. Throws code P2108

My kids and I was on the interstate and all of sudden my yukon reduce engine power.Dropping to 30 in a speed zone of 70.I was very afraid for our safety and appreciate there concerns for reducing engine power to save the truck,but that's very dangerous. So I paid to replace the throttle body and gas pedal cause that was the codes for the problem. But it's still doing the same thing and I don't have money to keep buying parts.Plus it a gm problem and I really need some help with the fixture..

Gm ignition switch recall: gmc refuses to honor the recall and fix this issue on both my SUV's. I can't be part of the class action until these repairs have been made, what a scam. I own 2 gmc yukon's slt and both qualify for the recall which I was never notified of from gmc. Neither car ever got repaired. The manufacture and local dealerships refused to do the repairs at no cost. This is after I paid these [xxx] over $1000 to fix this problem on one of my SUV's many years ago which did not get fixed because they claim they couldn't find what was wrong with my SUV's but they knew all along. I want gm to honor their legal obligations and fix my SUV's faulty ignition system. I only found out that there was a recal from the class action attorneys. Gm never notified me of any recalls ever!! Please help. Thank you. [xxx] parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

I was on my way home from work. I ended up getting just a few rain drops so I click my wiper switch one time, it didn't come on. ( puzzled ) so I repeated to get to water off window ,1 click at a time the wipers didn't come on until I was at high. Of course , now they are on high and rain is gone, now I can't get the blades to stop in the off position. Well, I had to pull over I couldn't concentrate on what just happened to my wipers? As well as drive. This happened on july 10, 2019. I've called gmc a couple times, 1st time they just closed next time I didnt transfer to service dept . I just think , there should be something to notify you , I just happened to get home before the storm hit. I was on a county road when it happened. Thank you for your time.

Speedometer sticks at highway speeds and registers at least 20 MPH higher than actual speed and needle fluctuates so you can not tell how fast you are going. Fuel gauge is inaccurate. Both are safety concerns. At 120,000 miles I am beyond gm's extended warranty. Should be recalled and fixed.
