Recreational Vehicle Lpg Tank Valve/gauge problems of the 2003 GMC Yukon

The cluster from all the dashboard has stop working the speedometer the gauges everything.

Speedometer and other instruments are inaccurately reading. Speedometer ranges from 25 - 70 mph overstated. Fuel gauge remains well in excess of full until about 7 gallons are left in tank. Oil pressure is registering well to the right of the highest reading. Problem began during cold temperature (around 10 degrees) and improves with temperature increases but has not resolved itself. Appears to be the same problem as gm special policy adjustment 07187a. The VIN is within the category listed by the policy; however, the vehicle is older than 10 years but fits within the mileage restrictions since the vehicle has less than 64,500 miles. This appears to be a known defect which clearly impacts safety. . Read more...

I keep having the display say "reduced engine power". I'll be driving on the highway, doing 65 in rush hour traffic, when all of the sudden the accelerator no longer accelerates and it displays "reduced engine power" on the gauge cluster display. From what I've seen online it appears to be an issue with the throttle position sensor on thousands of other similar vehicles with the same engine, chevy suburban's, silverado's, tahoe's, etc. I replaced the throttle position sensor and the harness (because I heard the harness might also be an issue) and I am still having the same problem with my truck. It has done it over a dozen times on one trip back from work (80 miles for me). I have to pull over to the side of the road (if possible) and turn off the truck, then wait a short period of time, then turn the truck back on. This usually fixes the issue, but it did not help me when it happened to me in the tunnel and I was going 5 mph (top speed during the "reduced engine power" mode, once your drifting stops (because you drift, it doesn't engage the brakes). I was extremely worried that I wouldn't make it out of the tunnel without get rear ended, and once I made it out, I was just outside of the tunnel awaiting roadside assistance, it was very frightening, with my daughter in the car.

The instrument panel gauges are sticking the odometer is not working at all the oil gauge is pinned and the other gauges also stick. The odometer and oil gauge is all the time and nothing has been done to repair the problem gm has informed me that they will not help me get this very dangerous defect repaired. This is a defect in the panel cluster not wear and tear or anything we have done.
