Frequent clicks on the pump when filling up fuel. I noticed this around 40,000 miles but I keep forgetting to have it check by the dealer. I pass the last smog check that is why it did not bother me. The frequent clicks on the pump when filling up is worse and irritates my wife when she fills up gasoline. She and I had to put a lot of pressure to seal nozzle to fill up gasoline. The frequent clicks happens even at the beginning even on an empty tank. …”
