Speedometer flutters and now gives erroneous reading, gas gauge gives false readings. I did some online research and found that there was a problem with the instrument panel cluster and a letter was sent by GMC. I am the original owner and never received a letter and now my instrument cluster is failing. And now am past mileage/years to fix, because I never got the original letter and never new there was a problem.
