NHTSA Complaint #11337503 — 2008 CHEVROLET IMPALA

THIS COOLANT CROSSOVER PIPE GASKET LEAK HAS BEEN A REPEATED AND MULTIPLE VEHICLE PROBLEM WITH THE 3.9L AND 3.5L AND GM ONLY CAME UP WITH 2 TECHNICAL SERVICE BULLETINS; THE LAST ONE WAS #07-06-02-006E: COOLANT LEAKING FROM ENGINE (REPLACE COOLANT CROSSOVER PIPE GASKETS) - (MAR 5, 2012). HOWEVER, THE NEW GASKET DESIGN PRESUMABLY REPAIRED THE LEAK. HOWEVER, IT DID NOT. I HAVE SEEN THIS ISSUE DISCUSSED ON SEVERAL WEB SITES WITH ALL COMPLAINING ABOUT THE SAME UNRESOLVED ISSUE. MY 2008 IMPALA WITH THE 3.9L V-6 HAS BEEN REPAIRED FOR THIS ISSUE ON THE FOLLOWING DATES, EACH TIME I WAS ASSURED IT WAS SATISFACTORILY REPAIRED: 02/09/2019 ' DIY DUE TO DEALERSHIP COST. REPAIRED PER GM TSB/GM TECHNICAL SERVICE MANUAL. 11/30/2016 ' DEALERSHIP. 03/10/2014 ' DEALERSHIP. 01/11/2013 ' DEALERSHIP. AND NOW, IT'S LEAKING AGAIN! I CHATTED WITH CHEVROLET ONLINE ON 10 APR 2020 AND CECIL SAID THAT WARRANTY HAD REPAIRED IT ONCE, BUT THE ISSUE HAS BEEN AND STILL CONTINUES. GM WOULD NO LONGER REPAIR THE LEAK. THIS IS WHAT I WAS TOLD: CECIL AT 15:40, APR 10, 2020: UNFORTUNATELY, ONCE THE DECISION IS FINAL THAT IT CANNOT BE CHANGED ANYMORE. BUT HERE IS WHAT WE SUGGEST, YOU CAN TAKE THE VEHICLE TO A CERTIFIED GM DEALERSHIP ABOUT THIS TO HAVE IT DIAGNOSED AND IT MIGHT THE SAME SYMPTOM BUT DIFFERENT ROOT CAUSE. WE CANNOT PERFORM DIAGNOSIS OVER CHAT. CECIL AT 15:41, APR 10: AND FOR ASSISTANCE, I HIGHLY SUGGEST THAT YOU SPEAK WITH THE CUSTOMER EXPERIENCE MANAGER OR CEM AT THE DEALERSHIP. HOWEVER, THE DEALERSHIP IS THE ONE WHO TOLD ME THAT IT COULD NO LONGER BE COVERED UNDER WARRANTY! THIS ISSUE IS SOMETHING GM SHOULD HAVE LONG RESOLVED WITH A BETTER SOLUTION. THIS LEAK IS A CONTINUAL PROBLEM AND GM DOESN'T OFFER ANY BETTER REPAIR OPTIONS AND WILL NOT REPAIR THE LEAK AGAIN.
