Purchased an 11 Sonata GLS with 2.4L GDI engine. Some thoughts after about 8k miles of driving.
Purchased car with 29k miles, looks as good as factory new. Noticed oil stunk like fuel, and changed it as soon as I got home.
Assumed it was due to dealer short tripping it, and not putting highway miles on the car.
Valvoline oil filter was causing a startup knock, so I changed to Hyundai OEM and Chevron Supreme 5w30 oil. Knock was filter related and is gone.
After 3750 miles, oil was jet black and stunk like fuel again. I drive 30 minutes each way to work and the car is not short tripped.
We drove to New Mexico and all over Texas in this car this fall/winter.
Changed oil with same Chevron/Hyundai filter combo. Again oil looks trashed after 3k miles.
Added Techron fuel treatment to car 2x so far. Car pings on 87 octane fuel from non Top Tier stations.
Does not ping at all on 89 from Top Tier Valero station.
I find it hard to believe that a 30k mile car would need valve deposit cleaning service, but not impossible I guess.
Overall car runs excellent and sounds interesting at idle, almost like a piece of farm equipment or sewing machine.
Previous owner or dealer put an orange dipstick on the car, which raises the level from 4.8 quarts to 5.2 quarts. I think Hyundai started doing this to reduce its claims for engine replacement in these cars.
Steering coupler is worn and steering has a bit of a knock to it. Will call dealer and see if this car has any warranty left on it. 6 dollar part and probably 3 hours labor to install a plastic gear that causes the clunking in the electric assist steering column.
Otherwise, like the car very much. It is just a car that I would not want my wife taking care of, as it requires more maintenance than our toyotas. Her girlfriend has a Kia Optima, I drove it the other day, it is way down on power, and pings like crazy. Also she is running the oil out to the non-severe maintenance schedule, and I bet the car is full of deposits and goo.
I'm considering a couple things, a BG 44k fuel system cleaner ($17), and maybe new spark plugs? I can't fathom why this car would ping on 87 octane.
I have an obd2 datalogger, I'm going to set it up to see how much timing is being pulled on 87 versus 93, etc.
