USA Today (5/27, Healey, 1.71M) reports, “If you drive a 2013 Cadillac SRX crossover SUV, your wheels can fall off.” Though apparently it has not happened yet. GM reported that “some wheel lug nuts have come loose on SRX models in General Motors’ test fleet.” It is, therefore, “recalling 18,871 SRX SUVs built from Jan. 31 2012 through Mar. 18, 2013, that have 18-inch-diameter wheels.”
