...I meant, the power peak occurs just before the engine "runs out of breath"

Went to go to store car would not start. 5 Minutes of trying got it 2 start once for 3 seconds. Killed battery and waited for jump. tried for another 5-10 Minutes it started for 10-15 seconds. I can hear the Fuel pump starting when i turn on Ignition, but can't smell gas, I'm thinking Fuel filter. if I am correct where is the filter. any other possibilities????

I have a problem imagining a fuel filter that would just clog all of a sudden without previous signs of starvation under high power.
#46 of 48 Sonata front suspension "thunk"
Mar 06, 2008 (7:01 am)
Update to "thunking" on 2008 Sonata. I have been in contact with Hyundai Consumer Reps. They have assigned a case number. They were pleasent yet unable to help. Both reps. I spoke with had NOT heard of this problem. They contacted the dealer, also set up an appointment with a Hyndai rep. After a test drive with the rep and Service manager at the dealership, the results were this. The thunking is normal for this type of suspension, it is a tuned "sport" suspension allowing for sports car performance rather than a soft ride, it is a "stiffer" suspension than other Hyundais.This car is a four cylinder, when I asked the rep why I have read reports that the six cylider does not seem to have this condition he stated because it is a heavier vehicle. The rep was willing to change out the struts, however he belived this would NOT change the condition. The dealership was willing to trade the vehicle with a trade in price of $15,000 - the taotal price I paid was $23,200. less than a month ago !!! No suprise there!!! I am going to take the car to a mechanic I trust and have him evaluate the situation. I' ll proceed from there. I do believe that Edmunds and all other organizations which post car reviews should include this condition in there reports.

That 2006 -07 and I guess 08 Sonata's have noisy suspensions is old news in as much as there have been posts here and Hyundai has issued a TSB to correct or minimize REAR suspension "thunks" on 2006 cars. There now seems to be FRONT suspension noise classified by some owners to be a "thunk". I have been following a specific owners process using a Hyundai repair facility to remove his front noise and the latest on that front, as reported recently, is that the front strut cartridges or inserts have been changed. This minimized but did not eliminate it.
I do not agree with your service advisor about either comment he made: that a "sport suspension" is inherently noisier than the "normal" version on the same car or that a V-6 being heavier (it may be but it is minimal) would cause one not to have the noise. I personally have recently rented both I-4 and V-6 versions of the GLS model. These were 2007's and having ~26,000 rental miles were hard used vehicles. I don't know if I am insensitive or what but driving both cars over temporary "winter patched" repairs on generally poor Pa roads I MAY have heard some suspension noise on the worst parts. Would this noise have been apparent if I was driving a Camry, Accord or some other brand car? I suspect so but don't know for sure. I have come to the tentative conclusion that individual owner sensitivity to noises may play a part in this "problem".

I would have the dealer replace the front struts and go from there. It may solve your problem. If they want to do something for free let them.
