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..

Trying to stop slowly and ABS system move my yukon to a point I almost hit the car in front of me. It happens when I try to stop under 10 miles per hour. Also 2wd drive drops to 4wd on highway and lose power. This is dangerous on the highway.

While traveling at highway speed and rounding a blind curve the traffic ahead had stopped due to a crash. I had to brake harder than normal and the brake pedal just kept depressing further and further until it was all the way to the floor. I wasn't stopping near fast enough and had to veer to the left into the median to avoid making contact with anyone else. It was raining and as I looked under my truck to look for why my brakes were ineffective but couldn't see anything at that time. I chose to try to drive home not sure why I had the problem stopping. The next day was dry and I had my brother pump the brakes while I look underneath and found numerous places where the brake lines were rusting at an alarming rate and one location where the rusted line failed. I repaired the leak I had found and when I tried to bleed the brakes from that repair I would begin an unending run of leaks up and down the metal brake lines for both the front and rear. This yukon has around 260k miles but those brake lines shouldn't be rusting through like they are. I have had more than 15 tahoes, yukons, yukon xls, suburbans, and pickup trucks from gm and never have I had such a run of brake failures as this 2004 model yukon was now going through. Gm says this is normal maintenance but how can one even see if a failure is occurring as many of these lines are concealed by the frame, chassis, and body. I have spoken to other owners of similar vehicles, be it pickups or tahoe's or suburbans of the 2000 to 2006 model years and nearly all have complained of chronic body rust issues but more importantly brake failures from brake lines rusting and then blowing out without warning. Many also cited that of the lines that are visible to inspect they would appear to be ok but just out of view one would have a sudden blow out with no way to see or know there was a problem since the lines are concealed.
