#10 of 19 Wats wrong with my 2009 Sonata limited V6
Aug 28, 2008 (3:16 pm)
Recently bought a 2009 Sonata limited V6 with NAV, ......and now its 350 plus miles and since past 2 days... the engine cries(noisy) like anything....when I start the engine and till the time it reaches 0-35 mph(with jerks while it shifts the gears), it feels like I am driving a used car/truck. Real terrible...no pickup...even if its a V6.
One of the dealers said it needs 89 Ocatne gas....I should not put 87 Ocatne..where as per my user manual... 87 Octane gas is fine.
Where as the dealer from whom I bought the car asked me to get the car tomow. to their service center..... as they said they r going to fix it..if not then replace the car. Where as its not typically expected of a new car if it really passed Quality tests.....
Let me know if anyone had similar problem in the past......??

I have a 2009 V6 Limited. Power is adequate, but I don't feel it's anything to write home about. Could use more low end torque.
Don't get me wrong, I am big fan of Hyundai, and love my Sonata... .but the Nissan/Infiniti VQ line of engines are definitely stronger, particularly in the lower rev band.
#13 of 19 2008 Hyundai Sonata Transmission problems
Oct 20, 2009 (6:21 am)
I have two problems
1) If I am driving in 50 MPH and I come to a complete stop, the car does change to a lower gear it simply turns off the engine
2) If I am driving in 40 MPH and then If I press the brake to reduce the speed and then make turn and then press the gas pedal to increase speed, the car just jerks for a few seconds before changing gear.
I have a feeling that the car has problems going from 2nd to 1st bear. Does anybody have the same problem. Are there any solutions?

The problem is the torque converter for #1 and probably #2. The torque converter in locked when you are stopping so there is no slippage to allow the engine to idle. This should be 100% in warrenty unless you have driven 100,000 miles.

Do you know how long it takes to fix it?

The dealer would know that probably a day of labor. The dealer will verify the problem first.
#17 of 19 2007 SONATA V6 FLOWMASTER MUFFLERS
Oct 30, 2009 (9:54 am)
I installed a pair of 40 series 2 chambers. They sound very good - no bumble bee sound, but my highway gas mileage dropped from 32 to 26. I guess it's a mistake to cut off the factory mufflers and sacrifice that many MPG's. My mileage to and from work has not changed??

Maybe the engine will adjust to the new mufflers or you are on the gas more because you like the sound

If your new mufflers restrict the flow any at all it will drop your HP and MPG. It
happened to me before. With catylitic converters the system may be thrown off.
Just the opposite happens if you open the flow you will gain HP and MPG like
when headers are installed, have done that also. I used to work on my own vehicles
but with all the new junk they have on them it takes a computer now.
