Open the full vehicle complaint log (all categories)REGARDING 2014 GMC SIERRA 6 CYLINDER FULL SIZE PICKUP. VEHICLE VIBRATES AS IF RUNNING OVER RUMBLE STRIPS AT APX 1500 RPM. LOCAL GM SERVICE CENTER AND GM CORPORATE REPRESENTATIVE STATED ABOVE IS NORMAL VEHICLE OPERATION. LOCAL GM SERVICE CENTER CORRECTLY SUGGESTED THAT TRUCK BE DRIVEN FASTER OR SLOWER TO PREVENT VIBRATION OR THAT VEHICLE BE DRIVEN IN 5TH GEAR RATHER THAN OVERDRIVE 6TH GEAR TO PREVENT VIBRATION. IF VEHICLE IS NOR DRIVEN FASTER OR SLOWER TO GET OUT OF VIBRATION RANGE, THE TRUCK WILL VIBRATE ENDLESSLY. 2014 GMC SIERRA IS AN UNSAFE VEHICLE. NEEDING TO SPEED UP OR SLOW DOWN TO PREVENT VIBRATION SIGNIFICANTLY INCREASES RISK FOR MVA. NEEDING TO DRIVE IN 5TH GEAR RATHER THAN 6TH GEAR REDUCES GAS MILEAGE AS REPORTED TO NHSTA. LOCAL MECHANICS HAVE COMMENTED THAT THE ABOVE VIBRATION COMPLAINT IS COMMON TO 2014 6 CYLINDER GMC/CHEVY FULL SIZE PICKUP TRUCKS AND THAT THE VIBRATION MAY BE SECONDARY TO CYLINDER DEACTIVATION AND CHASSIS RIGIDITY. IT CERTAINLY WOUND BE A SHAME FOR A COLLISION TO OCCUR OR FOR A PEDESTRIAN TO GET RUN OVER BY A DRIVER OF A 2014 GMC/CHEVY FULL SIZE PICKUP WHO HAD TO SPEED UP OR SLOW DOWN TO REDUCE EXCESSIVE VIBRATION AT APX 1500 RPM
