Instrument cluster. Gauges randomly stick or falsely read to include speedometer. Sometimes it will stick at a random speed. Other times it will peg at its max. Unknown if odometer is involved. Sometimes they reset after repeated start/off cycles. Was covered under a gm recall bulletin no: 07187b, page 8. Current odometer is 145,369. Should gm not repair this after the warranted period? This is just as dangerous now than it was at 70,000 miles. Oil pressure gauge very rarely reads correctly. I trailer tow often and correct oil pressure is imperative as is a correct speedometer reading. On the top of the page I downloaded from the federal safety agency is the number csc-10026542-8984. Please note that this began two years ago with a faulty amp gauge but within the last several months it has now affected all gauges but the fuel gauge, water temp and transmission temp. Possibly related is the heated seat on the drivers side. The heat is on all the time (on hi) and can only be shut off by unplugging the seat which deactivates the air bag sensor, power seat control and the like. I have not contacted gm at this time. Please advise me as to my course of action.

While driving on the highway and keeping up with traffic, I noticed my speed was 75mph. Slowing down to the posted speed limit I was suddenly getting passed up by everyone. It wasn't until I exited the highway and while waiting at a stoplight I noticed the speedometer was reading 10mph (while standing still). Checking gmc and chevrolet forums online, this seems to be a common problem and a definite safety concern. The reading on the speedometer while in park now varies between 10-20 MPH, and I have absolutely no idea how fast I'm actually traveling while driving. I've made an appt with the dealer to have it checked out, and I'm sure the repairs will be expensive!

Reduced engine speed warning light comes on and drops truck to an idle. I feel this is very dangerous in traffic and on highways. My mechanic has not been able to locate problem. All forums and online help has brought me to dead ends. This is my last resort, I believe gm knows what the problem is and am hoping they will do the right thing and recall before someone is seriously hurt or killed from this issue.
