Incident

Jul 4, 2025

Recently replaced o2 Sensor and cleared check engine status. I failed the state emissions test because the Cat indicates inc or not ready,(catalytic converter). The procedure to clear this condition is dangerous and unreasonable. It calls for accelerating to 55MPH or higher for 2-3 minutes then decelerating to 20 MPH, not using brakes, and travel for 2 minutes then accelerating back to 55MPH, repeating this process up to 5 cycles to clear the CAT status. Given the drive speed this procedure would have to be done on a highway and could very likely cause a collision. This is very hazardous and should not be a requirement to complete vehicle inspection.

I WENT TO A GUYS HOUSE WHO WAS SELLING A 2005 CHEVY SILVERADO WITH 114,000 MILES ON THE CLUSTER. HE DIDN'T HAVE THE TITLE UNDER HIS NAME. HE WAS TITLE SKIPPING. GAVE HIM 5,000.00 THAT HE WAS ASKING FOR ON 11/02/2020 THEN WENT TO FIND THE OWNER WITH HIS NAME ON TITLE. HAD HIM SIGN THE TITLE OVER TO ME. WENT TO DMV AND CHANGED THE TITLE UNDER MY NAME. THEN 11/28/2020 I RAN A CARFAX REPORT TO SEE WHAT MAINTENANCE HAS BEEN DONE ON MY TRUCK AND IT SAYS THAT MY TRUCK HAD MORE THAN 250,000 MILES ON IT. I CONFRONT THE MAN THAT SAME DAY. AND ASKED HIM IF HE CHANGED THE MILEAGE HE SAID YES. I THEN ASKED HIM TO GIVE 2,000.00 BECAUSE THE TRUCK IS NOT WORTH 5,000.00 HE SAID HE WAS NOT GOING TO GIVE ME A PENNY. SO I MADE A POLICE REPORT THAT SAME DAY ON 11/28/2020

LIKE SO MANY OTHERS, I STARTED TO HEAR A TICKING AT STARTUP AND SOMETIME AN EXHAUST SMELL IN THE CAB. I FOUND 2 EXHAUST MANIFOLD BOLTS BROKEN ON EACH SIDE. IT CAN GET BAD ENOUGH TO OPEN A WINDOW AT TIMES. DEALER SAID IT'S A COMMON PROBLEM. THERE SHOULD BE A RECALL ON A EMISSIONS AND SAFETY ISSUE. I TAKE VERY GOOD CARE OF MY TRUCK AND THIS SHOULD NOT HAPPEN. I SEE IT HAS BEEN A PROBLEM SINCE 1999.WHAT CAN WE DO TO GET REIMBURSED FOR THE COST OF REPAIR? IF I HAVE AN INDEPENDENT REPAIR WOULD GM EVER COVER IT OR DOES IT HAVE TO BE DONE BY A HIGH COST DEALERSHIP? THEY GOT VW FOR EMISSIONS WHAT ABOUT GM?

CRACKED CYLINDER HEAD AND ENGINE. THIS ALLOWS ANTIFREEZE COOLANT TO MIX IN WITH THE OIL IN THE ENGINE AND GOES THROUGH THE EXHAUST, THIS ALSO GUMS UP THE OIL PARTS IN THE ENGINE AND REQUIRES NEW CYLINDER HEADS TO BE INSTALLED OR ENGINE REPLACED. I JUST RECENTLY WAS MADE AWARE THAT THE GENERAL MOTORS IS AWARE OF THIS PROBLEM WITH THERE ENGINES. AND ALSO WAS MADE AWARE THAT THE GENERAL MOTORS HAS SINCE FIXED THIS PROBLEM AFTER 2007, BECAUSE THIS IS NOT A PROBLEM THAT COULD CAUSE DEATH IT IS NOT LISTED AS A RECALL. THIS PROBLEM IS NOT MADE AWARE TO THE CONSUMER BUT IS PUBLISHED IN TECHNICAL SERVICE BULLETINS. THIS IS KNOWN PROBLEM BY GENERAL MOTORS. IT IS GOING TO COST BETWEEN $2500 TO $5000 TO REPAIR. *TR
