WITH THE ENGINE STILL RUNNING, THERE WAS NO ACCELERATION. CYCLING IGNITION OFF/ON BROUGHT THINGS BACK TO NORMAL. REPORTED TO THE DEALER THROUGH HONDA, CA. DEALER SAID CAUSE WAS "LOOSE BATTERY CABLE."

THIS IS THE SECOND TIME THE DEALER HAS FOUND A LOOSE BATTERY CABLE AS THE CAUSE OF AN ISSUE. IN EACH CASE, THE NEW BATTERY WAS NOT INSTALLED BY THE DEALER, BUT AT THE SAME SAM'S CLUB SERVICE CENTER. BEFORE THIS REPORTED INCIDENT ABOVE, AND ABOUT SEVERAL WEEKS EARLIER, A NEW BATTERY WAS AGAIN INSTALLED BY SAM'S CLUB. HAVING BEEN ADVISED OF THE PREVIOUS "LOOSE CABLE," THE SAMS CREW WAS ASKED SPECIFICALLY TO ASSURE THE BATTERY CABLE WAS SECURE. THE TECH SUPERVISOR REPLIED THAT IT WOULD BE DONE. SAFETY WAS AN ISSUE.
