ENGINE

TOOK VEHICLE IN FOR SERVICE AND WAS TOLD THAT A EXHAUST MANIFOLD BOLT WAS BROKEN. VEHICLE WARRANTY HAD JUST EXPIRED AND REPAIR WOULD BE ABOUT 900.00. I RESEARCHED THIS ISSUE ONLINE AND FOUND THAT SEVERAL OTHER PEOPLE HAVE HAD THIS SAME ISSUE WITH THEIR GM PRODUCT. THIS SHOULD BE INVESTIGATED AS A POSSIBLE RECALL. THIS BEING AN EMISSIONS ISSUE WILL CAUSE MY VEHICLE TO FAIL THE EMISSIONS TEST AND COULD POSSIBLY CAUSE EXHAUST IN THE PASSENGER COMPARTMENT.

ENGINE AND ENGINE COOLING

ON DEC. 23, 2011, I TOOK MY SILVERADO INTO JOE FIRMENT FOR AN EXHAUST LEAK (WHICH IS AN EMISSIONS PROBLEM), SO I WANTED IT FIXED IMMEDIATELY. THEY FOUND NOTHING. ON MAY 22, 2012 I TOOK MY SILVERADO BACK TO JOE FIRMENT FOR THE 3RD TIME FOR THIS SAME ISSUE - EXHAUST LEAK. AT THAT TIME THEY HAD FOUND ONE BROKEN BOLT ON THE EXHAUST MANIFOLD (ACTUALLY THERE WERE TWO BROKEN BOLTS THAT I FOUND PERSONALLY UPON FURTHER INSPECTION). MY WARRANTY COVERED THE MANIFOLD BUT HAD JUST EXPIRED ON MAY 7, 2012. I ASKED THAT THEY HONOR MY WARRANTY SINCE THE PROBLEM HAS BEEN THERE SINCE 2011, BUT THEY FAILED TO DIAGNOSE IT. JOE FIRMENT REFUSED TO HONOR MY WARRANTY. I RESEARCHED THIS ISSUE ONLINE AND FOUND THAT SEVERAL OTHER PEOPLE HAVE HAD THIS SAME ISSUE WITH THEIR GM PRODUCT. THIS SHOULD BE INVESTIGATED AS A POSSIBLE CLASS ACTION SUIT. HOW MANY SIMILAR COMPLAINTS ARE ON RECORD? THIS BEING AN EMISSIONS ISSUE WILL CAUSE MY VEHICLE TO FAIL THE EMISSIONS TEST REQUIRED TO RENEW MY LICENSE PLATES. THIS NEEDS TO BE CORRECTED AND SHOULD BE COVERED UNDER MY ORIGINAL WARRANTY SINCE THE PROBLEM BEGAN WITHIN THE WARRANTY PERIOD. THE DEALERSHIP SHOULD HAVE DIAGNOSED IT ON THE FIRST APPOINTMENT FOR THIS ISSUE.

ENGINE AND ENGINE COOLING:ENGINE:DIESEL

WITH THE NEW EPA REGULATIONS REQUIRING THE DPF ON DIESEL ENGINES THERE IS A PROBLEM WITH GM TRUCKS, WHERE AS WHEN THE TRUCK GOES INTO REGENERATION MODE AT LOW SPEEDS, (IE HEAVY TRAFFIC) THE FUMES EMITTED ARE SUCKED BACK INTO THE CAB OF THE TRUCK THROUGH THE VENTILATION SYSTEM. IN MY TRUCK REGENERATION WILL HAPPEN EACH TANK FULL OF DIESEL (1-2 TIMES PER WEEK). AT HIGH SPEEDS THIS IS NOT AN ISSUE. WHEN THE FUMES ARE SUCKED BACK INTO THE TRUCK THE OCCUPANTS EYES WILL BURN AND YOU START TO FEEL SLEEPY AND OR SICK TO YOUR STOMACH. I HAVE RESEARCHED ON-LINE IN SOME OF THE FORUMS AND OTHERS ARE COMPLAINING THAT CHILDREN WILL ACTUALLY VOMIT FROM THE SMELL IN THE CAB. IT SEEMS THERE IS A FIX TO THIS BY CHEVY, HOWEVER THEY ARE RELUCTANT TO CORRECT THE PROBLEM UNLESS YOU MAKE A LARGE ENOUGH STINK AT THE DEALERSHIP LEVEL. I IMAGINE BECAUSE OF THE COST! IT SEEMS TO ME THAT AN ISSUE LIKE THIS WHERE FUMES ARE BEING PULLED INTO THE VEHICLE IS A SAFETY PROBLEM THAT NEED TO BE ADDRESSED BY AN AUTHORITY SUCH AS YOURSELF. I CANNOT BELIEVE THAT THESE FUMES ARE NOT GOING TO EVENTUALLY CAUSE HEALTH ISSUES, OR EVEN WORST SOMEBODY FALLING ASLEEP AT THE WHEEL AND CAUSING AN ACCIDENT. I JUST FOUND OUT THAT THERE IS A TSB FROM GM ON THIS ISSUE THAT I HAVE BEEN EXPERIENCING FOR OVER A YEAR NOW BUT THE DEALERSHIPS DON'T TELL YOU. I WILL BE BRINGING MY VEHICLE TO THE DEALERSHIP NEXT WEEK AND FORCING THIS ISSUE TO GET THE PART THAT NEEDS TO BE FIXED REPLACED.
