I had a 2001 300M...... best car I ever owned. The x-wife still has it.... 300,000KM and going strong. Only repair has been a flat tire!
I loved that car.
Currently I have a 05 camry and I am thinking whether I should buy 2011 sonata to replace it. Then I have been to the dealer to test drive the new car and I found there is no big difference for road noise between the two cars. What do you think of it? Any thought will be welcome! Thank you very much!
BTW, on a Hyundai with a manual transmisison, the cruise is so quick and accurate you can almost drive the car without using the accelerator.
Here is a patent that reduces that. Judging from the intro it is a common problem with DI engines

I am wondering if that problem has been solved with the Theta II engine?
Just to reduce the risk of deposits I will continue to use only Shell when I get my Sonata. May also be a good idea to switch to full synthetic oil during the first oil change. Any technical guy that could provide us with some guidance here?
hi-way, see what you think. I have the 09/10 SE-v6 love it. Go check the new 11
out for yourself, a beautiful awesome ride. the build quality is excellent. Then go
try the rest, you will see.
Happy Hyundai owner::
I am thinking of buying a 2011 Sonata Limited Model (without navigation). I am wondering what will be the best price that I can bargain for this. Anyone got the car below invoice price? Welcome pricing suggestions from anyone who recently bought. Thanks.

"The DI invention concerns an internal combustion engine, especially an Otto engine, with a fuel injector.
Gasoline engines with direct injection of the fuel into the combustion chamber, i.e., not into the intake port, suffer especially from the problem of the formation of carbon deposits on components. Carbon deposits form especially in the neck region of intake valves. A more exact analysis of how these carbon deposits form leads to the following result: Oil and fuel constituents first form a sticky coating on the components. These constituents are chiefly long-chain and branched-chain hydrocarbons, i.e., the low-volatility components of oil and fuel. Aromatic compounds adhere especially well. This sticky base coating serves as a base for the deposition of soot particles. This results in a porous surface, in which oil and fuel particles in turn become embedded. This process is a circular process, by which the coating thickness of the carbon deposits continuously increases. Especially in the area of the intake valves, the deposits originate from blowby gases and from internal and external exhaust gas recirculation, and in this process, the blowby gases and the recirculated exhaust gas come into direct contact with the intake valve.
Especially in the area of the neck of the intake valves, excessive carbon deposits have extremely negative effects for the following reasons: In the case of Otto direct injectors, the successful ignition of the stratified charge depends to a great extent on correct development of the internal cylinder flow, which ensures reliable transport of the injected fuel to the spark plug to guarantee reliable ignition at the spark plug. However, a coating of carbon deposits in the neck region of the intake valve may interfere so strongly with the tumble flow that ignition failures may occur there as a result. Under certain circumstances, however, ignition failures can lead to irreversible damage of a catalytic converter installed in the exhaust gas tract for purifying the exhaust gas. Furthermore, the coating of carbon deposits in the neck region of the intake valve causes flow resistance, which can lead to significant performance losses due to insufficient cylinder filling, especially in the upper load and speed range of the internal combustion engine. In addition, the carbon deposits in the neck region of the intake valve may prevent correct valve closing, which leads to compression losses and thus sporadic ignition failures. This in turn could irreversibly damage the catalytic converter. There is the potential for small particles to break away from the coating of carbon deposits in the neck region of the intake valve and get into the catalytic converter. These hot particles may then cause secondary reactions and corresponding local damage of the catalytic converter. For example, a hole may be burned in the structure of the catalytic converter.
Globular deposits are found especially on the valve stem downstream from a partition plate in the intake port. Due to the dripping of high-boiling hydrocarbons from the partition plate towards the valve neck or valve stem, globular carbon deposits eventually form there by the sequence of events explained above. These deposits on the valve stem can result in flow deficits due to undesired swirling and turbulent flow around the globular carbon deposits. This may persistently interfere with the formation of stable tumble flow from cycle to cycle.
A possible solution would be to keep these sources of deposits away, for example, from the intake valve, by completely eliminating exhaust gas recirculation and the introduction of blowby gases into the intake port. However, with the combustion behavior of modern reciprocating internal combustion engines, at least external exhaust gas recirculation and the introduction of blowby gases into the intake port are absolutely necessary for reasons of emission control and fuel consumption, so that this approach is not possible. "
Thanks for the clarification.
DFI has been around a long time, mostly on higher end cars. Do you know how it's working for them?
Yes,. DI has been around and the above quote is a response to problems they have been experiencing. Honda apparently dropped their DI because of that. If you do a google you will find some discussions going on about this.(VW, Audi etc) Some engines are already badly build up at 40K. :surprise: To clear it means opening the engine and manually removing it with the help of some chemicals (i.e $$$) There are patents out their to reduce this - some more costly and/or effective that others. The reason why I posted this is to try and find out what Hyundai did about the deposit build up in their design.
P.S. The 2011 is significantly better in handling and in many other ways as well. The only negative is over concrete interstates with expansion joints it is REALLY noisy and rough. The 2009 was much quieter.
PP.S. I have enjoyed reading all the posts (lurking for the past two months) . Thanks for so much good info.
Didn't want to spend more time in the dealership going over features so I took the key, my manuals (all 1,000 pages) and left. Of course I have not had time to pull out the manual...I'm thinking "how hard can this be? My last car was a BMW 5 series and I had nav and bluetooth...I can operate this." Well it seems I CAN'T...
My contacts don't appear, even though it says my phone (Droid) is connected...and when you shut the car off, it disconnects the call. In the BMW your call stayed connected until you ended the call or switched it to your phone. Secondly, I searched for a bank on Saturday, but ended up not going...and I can't figure out how to cancel it from the nav. Everytime I get in the car it tells me directions to the bank...lol...so i just resorted to muting the thing. I guess I know what I'm going to be doing tonight...READING!
On a positve note, I love the sound system, interior styling (looks absolutely beautiful at night), touch screen system, smart key (absolutely best feature for me!). I love not having to fumble with keys as you can unlock and lock doors, start and end engine without having a key in your hand...LOVE IT!
I'm still adjusting to the rear view camera. Also, it could be a little easier on bumps etc, but again I came from a BMW so I just need to learn to cool out and take it easy So far, I am very happy with my choice, especially considering I never even noticed Hyundais before.
As far as the bank, hit the route button and cancel the route.
I'm not sure just being connected to the Droid is enough. Did you go through the pairing steps already?
No soliciting!
Couple days ago, I figured out that disconnection was NOT actual disconnection. I was on the phone via bluetooth on Sonata with my wife on my way back home. I parked and turned off the engine, of course my call got disconnected. When I walked in, I saw my wife was still holding her cell phone. She said she was able to hear all (Car door open/close, Walking to the door etc) through her phone. I looked at my phone and there was no sign I was still on the line. I slided my phone up and down to disconnect completely.
It could be just my phone, but to hit end call button on your steering wheel before you turn off the engine wouldn't be a bad idea.
They're all $2,400 to $3,500 under invoice.
A SE Auto for $20,530 is not outstanding? A GLS Auto for $18,464? A Limited for $22,828???

Posting the deal and the dealership is fine though.
So they are out there, unlike the SE with NAV that just started being produced, as was posted here earlier.
this same realization came to me when looking at the 2011 Sonata's yesterday! why for a 28k dollar limited, where you get REAR HEATED SEATS, do you not get a power front passenger seat for that price? the logic escapes me! if you can afford and spend the money to put a rear heated seat in a car, which I like because no one else in that segment even offers that, why can't you spend a little money and put a power front passenger seat in the car! the logic of that just escapes me!
sorry if I sound a little crazy,and I know for most this power front passenger seat wouldn't be a deal breaker, but I've had two spine surgeries and have a really sensitive low back so something like a power front passenger seat, even just a four-way one, is a big deal in my book! c-mon Hyundai, don't be like Nissan!
You must not pay 26k-30k for a car that doesn't have a front passenger seat! Sorry, I know what you meant but couldn't resist.
I know Camry offers it as an option and MSRP probably is less than 30k. I am not sure if Toyota is in your mind though. You might want to look for a different brand car that has a softer ride than 2011 Sonata anyway because of your low back.
currently, the Accord, Camry, Malibu, and Fusion offer a power front passenger seat in their mid to top line models, only the Altima and Sonata don't; I'm hoping if I continue to write letter on a yearly basis and nag Nissan and Hyundai they will eventually put one it because Nissan and Hyundai know more about styling then Honda, Toyota, and Chevrolet do!
though, I really like the rear heated seat in the limited! it might be worth it to sacrifice the power front passenger seat in order to get rear heated seats! because I could use the heat on my back when sitting in the rear of the car!! I'll let my family sit in the passenger front seat :P
Seems like the Max is a large car but I know it's really not. I guess it has that perception because the Altima is Nissan's midsize entry and then you have.........the Maxima. :confuse:
I don't know though, had the 2011 Sonata been out last summer when I was shopping I might have been in a entirely different car then the one I am in now!
oh well though, kudos to Hyundai for the ten times better styling on the 2011!
Men purchase most cars but women influence them. The car makers are missing a big selling benefit here.
