While highyway driving for 6 hours the âCheck system chargingâ light came on for a few minutes, then went off for 10 or so minutes, then came back on. I was 10 miles from exit. I exited and left the car running while I checked in to motel. Drove to a parking place, turned off car engine, took a bag to room. When I came back out, flames were flaring from under the hood from battery area near fight front. The car had about 33,500 miles on it. A few weeks before, a âcheck batteryâ light had come on briefly. I took the car to dealership and told them about the battery light. I was going on a long trip so I told them to check everything. They replaced the battery and claimed to have checked the alternator, which they said was good. Even though the car only had less than 33,000 miles at that point, this was the fourth battery the car had had put in. 1) the original, 2) second put in by the same dealer, 3) a third when my battery went dead at a casino le one night. The valet charged it and I drove to an all night Autoxone where I bought a new batttery, and 4) the last one a few weeks ago. The Acura had a hard cardboard engine cover that you have to unscrew and remove to access the battery or the rest of the engine. This cover was completely burned up. The car was totaled. I believe the cardboard engine cover played a big part of the fire. Note: the fire occurred at Prescott, Arkansas. I had driven about 7 hours from Austin, Texas that day. The car was serviced in Las Vegas
