NHTSA Complaint #10344604 — 2002 BMW M3

I OWN A 2002 BMW M3. THERE ARE SIX CAMSHAFT BOLTS BEHIND A PLATE COVER. BMW SPECED BOLTS THAT WERE TOO SOFT UNTIL 2004 WHEN THEY CHANGED BOLT SPEC TO A HARDENED STEEL WITH LOCTITE. PRIOR TO THIS THE BOLTS HAD NO LOCTITE. THE ISSUE IS STARTING TO SURFACE ALL OVER THE WEB. THE FAILURE IS THAT THE BOLTS DO NOT STAY SCREWED IN. THEY BACK OUT AND STOP AGAINST THE PLATE COVER. EVENTUALLY THEY SHEAR OFF AND IF THIS HAPPENS IT CAUSES CATASTROPHIC FAILURE TO YOUR ENGINE. IN MY CASE I WAS GOING 15MPH SO THE DAMAGE WAS ONLY $10,000. THE CAR HAMMERED TO A STOP. BMW IS REFUSING TO ACKNOWLEDGE THE ISSUE SUGGESTING OUT OF WARRANTY. MY CONCERN IS THAT I HAVE 60K ON THE CAR WHEN THE ISSUE OCCURRED FIRST. A P0011 CAMSHAFT TIMING FAULT COMES UP. A BMW SERVICE CENTER CLEARED THE FAULT AND REPLACED SOME COILS AND SPARKPLUGS ($663) AND SENT ME ON MY WAY. THREE DAYS LATER THE BOLTS SHEARED. THE DEALERSHIP SAID THEY "HAD NEVER SEEN THIS BEFORE". THEY ALSO SAID BMW HAD ISSUED NO BULLETINS TO ADDRESS THE BOLTS. EVERY INDEPENDENT BMW FACILITY I INTERVIEWED IN PORTLAND WAS WELL AWARE OF THE ISSUE AND ALREADY DOING ENGINE REBUILDS FOR THEIR CUSTOMERS. I THINK THIS IS GROSS NEGLIGENCE ON BMW'S PART FOR NOT ACKNOWLEDGING THE ISSUE AND DEALING WITH IT. I ALSO THINK THE DEALER IS GUILTY OF CLEARING THE FAULT WITHOUT CHECKING FURTHER. THE BID ON MY WORK IS $10,000 (TWO VALVE HEADS AND A VANOS SYSTEM PLUS 50 HOURS OF LABOR). THIS IS AN ESTIMATE UNTIL THEY PULL THE ENGINE APART MORE. ONLINE YOU CAN SEE ON YOU TUBE MY ISSUE BY WATCHING THIS VIDEO. ON ALL THE FORUMS THERE ARE THREADS TO SEE THE ISSUE. YOU CAN SEE THIS BY A GOOGLE SEARCH OF "BMW CAMSHAFT BOLT SHEARING" HTTP://WWW.YOUTUBE.COM/WATCH?V=R6RDVBHSCFG BOTTOM LINE IS IF THE BOLTS ARE NOT REPLACED EVENTUALLY THEY WILL SHEAR OFF AND CAUSE CATASTROPHIC ENGINE DAMAGE. THE FASTER THE SPEED OF THE CAR THE WORSE THE DAMAGE. THE PROBLEM IS APPEARING IT SEEMS AFTER 30K AND FOR MANY INCLUDING ME BETWEEN 60-90K. *TR
