2011 Hyundai Elantra White Smoke when accelerating
Bought the car new in 2011 and it has been well care for, however, it is not driven regularly. Only has 45,000 miles, but oil changed regularly, etc. It's my kids college car, thus the reason for not a lot of mileage. Dad (me) makes sure it gets regular maintenance.
Anyway, taking if for inspection/emissions test and an oil change I hit the gas when the light turned green and got a large clould of white smoke. Car seems to be running correctly otherwise, doesn't have a lot of power, but I don't think it ever did. Any ideas?
Also getting a vibrating/rattling noise under the car, sounds like maybe a loose exhaust, but don't think the two are connected.
