In the middle of the taxiway, while I was traveling my truck turned off while it was running and did not turn on again, putting my safety at risk by being in the middle of the taxiway, after several minutes the truck was able to be removed from the road, then I was able to investigate that I am not the only one that the same thing has happened to him, there is no Safety Recall in this regard, the GM fabric is aware of these cases but only wrote a TSB, it was diagnosed with the scanner and it gave code U1800, before the event there were no lights warning but after the event there is a check engine light on.

The exhaust manifold bolts are breaking on the 6.0 engine. I think gm should do this repair since I have talked to several people and this is very common. It is a design defect as far as I am concerned. I have put up with this as it started as a small leak but is getting worse.

The vehicle goes into reduced engine power while driving. The engine loses power to about 20 MPH. If driving 70 MPH it is very dangerous because the sudden reduced engine power will cause a severe accident and possibly kill somebody. This has been happening the last few months.

At freeway speeds I noticed the oil pressure had dropped to almost 2 out of 10 on the pressure gauge. I stopped as soon as possible and let the engine cool for 20 minutes. I checked the oil level and color. It was ok in both respects. After another 30 minutes I restarted the engine and continued home. I watched the pressure gage for another hour and saw the pressure reading continue to fall to a dangerous level but there was nothing I could do. The next day I took the truck to the chevy dealer in el centro, ca 92243 for their analysis. They said it was only poor oil and needed changing. I let them service the truck as they wished. They also scanned (swept) the gauges and changed the oil and sent me on my way. The next day it did the same thing. I did not return to the dealer as I was not prepared for an argument.
