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..

Engine losing coolant, with no apparent signs of leakage. Coolant appears to be leaking into the engine oil, causing it to sludge, thereby causing engine failure. GM is aware of an issue and issued tsb 06-06-01-019B for defective cylinder head casting. I bought this car used last year and now owe 10000 for a car that needs a 6000 engine replacement. GM should be made accountable for this since they are well aware of the issue, per their own directive.

Surge happens while driving, then engine light comes on, decreased engine power occurs, tracktion stability indictors comes on. Car looses power. I have to pull over off the road, put into park, cut ignittion off, wait a few minutes and then restart the car. This could happen several times while driving.the vehicle is in motion and this is a driving hazard and big safety issue, it has happened on city street and on a highway. It happens daily.

Faulty castech head caused coolant fluid to drain into block therefore destroying motor. GM has known about these faulty heads and refuses to work to resolve problem. Technical service bulletin 06-06-01-019B.

Since getting this car in 2005, my husband and I have experienced reduced engine power. Whether going 40mph on a 2 lane road or 70 on the interstate, this continues to happen. We have had this issue "fixed" twice, spent about $1000 on 2 separate "repairs, " yet the problem persists. I cannot tell you how scary it is to be going with the flow of traffic and then have your engine power reduced. To be going 70 and then forced below 70 is dangerous. We could have been hit and killed trying to accelerate and pass someone. This actually happened. I know numerous GM owners have had this problem across numerous vehicles. Why haven't you forced them to fix it" is it because the government bailed them out, and it would be detrimental to the economy" safety and reliability on roadways should be important, too.

My car began to have a build up of slugs and began loosing oil pressure and coolant and needed oil added and coolant frequently. Oil pressure flat-lined in January of 2012 and it was taken to my mechanic. The slugs were cleaned and a new oil pump was placed because of the build up of slugs. I was advised to change the oil frequently to clean the slug out but it continued to build up and the mystery of loosing coolant oil pressure has bottomed out two more times and I found a article on the internet that a number of GMC vehicles including mine were built with defective cylinder heads due to cracks over time which allows coolant to leak into engine and mix with the oil which builds up slug. I want to know why a recall does not exist. This has cost me several thousands of dollars....I need GMC to man up to the problem and fix it.

Today when starting my 2004 Yukon, the information center displayed the messages: "stability control disabled", "engine power reduced". and the vehicle would not go over 20 mph on a level surface and barely 3 mph up a moderately steep hill. I had to pull over on route 80, drive on the shoulder and thankfully made it to a dealer. I've heard of so many GMC vehicles having this same issue. We need a solution before someone gets killed!
