AFTER BEING STOPPED LIKE AT A STOPLIGHT, THEN WHEN IT'S TIME TO ACCELERATE, THE TRUCK HAS A HARD JERK TO IT, AND IT DOESN'T WANT TO DOWN SHIFT. PLUS WHEN RIDING DOWN THE ROAD, THE TRUCK WILL LO JUST SUDDENLY JERK SO BAD THAT IT FEELS LIKE SOMEONE RAN INTO THE BACK OF THE TRUCK. THIS HAS BEEN GOING ON FOR A LONG TIME, AND I HAVE TAKEN IT TO THE DEALERSHIP 4 TIMES AND THEY SAID THEY COULDN'T FIX IT. I EVEN RODE WITH THEM, AND IT DID IT. THEY STILL DIDN'T WANT TO FIX IT.

ABOVE 35MPH I BEGIN TO GET AN EXTREME SHAKE AND VIBRATION. IT GETS MORE AND MORE PRONOUNCED AS I DRIVE. AT 65MPH IS NEARLY UNBEARABLE, AND SHAKES AND VIBRATES VIOLENTLY. IT GIVES ME HEADACHES, AND I CAN FEEL IT IN MY ARMS AS I DRIVE. I FIRST NOTICED IT ABOUT 100 MILES AFTER BUYING THE TRUCK. IT NOW HAPPENS DAILY. *TR

NOTICED VIVID AND PERSISTENT ENGINE VIBRATION SHORTLY AFTER PURCHASE - WITH NO ASSOCIATED CHECK ENGINE CODE. VIBRATION HAPPENS AT ALL ENGINE AND AMBIENT TEMPERATURES (ESPECIALLY BELOW 50 DEGREES FAHRENHEIT), AT ALL ALTITUDES, REGARDLESS IF IN PARK, NEUTRAL, OR DRIVE. VIBRATION IS SO NOTICEABLE, YOU CAN WATCH THE WAVES VIBRATE THROUGH A CLASS OF WATER WHEN PLACED ON THE DASHBOARD. TAKEN TO TWO DIFFERENT DEALERSHIPS AND BOTH HAVE STATED THE VIBRATION EXPERIENCED IS PER NORMAL DESIGN FOR 6.2L ENGINE. HARD TO BELIEVE GM WOULD DESIGN A $65K+ VEHICLE THAT PURPOSELY VIBRATES/SHAKES. ESCALATED THROUGH GM CORPORATE (SR# 8-3108393XXX), TO WHICH THEY CONFIRMED TRUCK IS RUNNING AS DESIGNED. SINCE THE ENGINE WAS NOT THROWING A CODE, NO FURTHER INVESTMENT/RESOLUTION WAS NEEDED ON THEIR END. THEIR SOLUTION TO ME...SELL THE TRUCK IF NOT HAPPY. OF COURSE THEY DID NOT SAY THAT, BUT THAT'S THE WAY I INTERPRETED THEIR RESPONSE TO MEAN. BUYER BEWARE.
