Replying to: drezworld (Dec 20, 2007 4:44 pm) Okay, let's figure this out. Since there is an incredible lack of info, this post will be full of questions. You say the engine overheated and the radiator "blew out" and coolant now comes out the oil filter. Do you know why the car overheated? I am presuming that if coolant comes out the oil filter, well by golly, so has the oil. So, did the engine overheat because there was no oil in the engine? If so, your engine is toast. You say the radiator blew...just what does that mean? Did you or a shop replace the radiator? Are you just jerking our respective chains?

Replying to: autokritiker (Dec 20, 2007 6:19 pm) why? Max torque and HP are achieved way B4 these RPM's. What's the point? Replies to this message: hotrod54 (Dec 22, 2007 8:31 pm) autokritiker (Dec 23, 2007 5:01 pm) autokritiker (Dec 23, 2007 5:03 pm)

Replying to: craigbrooks (Dec 22, 2007 7:28 pm) If an engine is able to breathe better, wouldn't the HP peak occure at higher RPM? I thought the power peak usually happens after an engine "runs out of breath" as they say.   With better breathing, and a tweaked chip to push more fuel into the engine at high RPM, and maybe some bigger injectors, you'd assume an engine would make more power at a higher -RPM power peak.   The question is, how long could the engine's internals handle the extra RPM and power? I guess we don't have any Hyundai "ricers" in here yet. Replies to this message: autokritiker (Dec 23, 2007 5:03 pm)

#44 of 48 2003 Sonata L4 240k Mi by n5wxb Feb 24, 2008 (5:30 pm)
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????

Replying to: n5wxb (Feb 24, 2008 5:30 pm) 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" by shadow26 Mar 06, 2008 (6:01 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. Replies to this message: craigbrooks (Mar 08, 2008 8:32 am)
#47 of 48 old news by targettuning Mar 06, 2008 (7:21 am)
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".

Replying to: shadow26 (Mar 06, 2008 6:01 am) 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.
