I was the ex owner of sonata yf 2011. Decided to trade off last yr nov.

The aircon not blowing cold air is normal due to cbu from korea wth heater & the sunroof absorbed too much heat. U need atleast 10-15min in order to cool down the temp esp if the car parked under the sun or even in super warm days. Nothing really wrong unless after 20-15min still hot.

I resolved this by adding 2nd layer of tinted glass on top of ori tinted!  The car cooled after 5 min thereafter.

Not much problem wth this car actually except irritating sound from the sunroof mechanical parts & also the doors' covers sound.

Cabin take longer time to cool down is OK but if you can't feel any cold air at all the compressor is probably konk, agree?

How much did you trade in your 2011 Sonata?

That's why I said hv to wait till 10min to confirm. It's like that ever since I got the car in 2011. Only after i double tinted, I managed to reduce to 5 min

Rm58k to trade off. Reason: getting huge discount on year end sales for camry hybrid. And my current far away work place incurred too much of $$ on fuel.

The second hand value is quite poor, like Conti car. A 2.0L 2011 Camry can get at least rm10K higher and new price was the same.

Hi all Sifus,

I am planning to get a Hyundai Sonata 2011 from a local car dealer. After spending a day viewing all those cars, I found something in common.

Air Conditioning problem.

It only blows up hot air and no cold air at all. All dealers are telling me that the car hasn't been driven for the past 1 month and probably the air cond gas needs some refilling.

NONE of these Sonata is giving out cold air (I probably viewed about 6 units today).

I am wondering is there some kind of technical reasons behind this or is it so "suay" that all 6 units are facing a faulty air conditioning system?

Besides that, is there any well known problem for these Sonatas? I searched google but mostly are minor wear and tear issue. Of course, I would hope to get to know more about these cars =)

Thanks a lot Sifus =)

Somehow expected dy.. That's also one of the reasons I disposed last year rather than wait 

I thought Sonata was at least 20K cheaper than Camry.

Been driving Japanese all these years. I can only say the Sonata feel more solid over Camry (office had a camry hybrid, and a 2.0). Perhaps that would also mean its heavier as well. Im not really sure if I got used to it compared to Camry which I drove only a few times, but I do think the driving dynamics is better on the Sonata.

Sonata outlook still good. However as u agreed, the peryy sound from the sunroof, seats & even door panels and lastly also suspension sound pissed me off.

On the soft suspension, I cannot connent bcos I switched to 18" rim & feel too hard pulak haha. Anyway, my new camry hybrid, the suspension just nice. Not hard & too soft. Just ngam-ngam. Handling also surpringlt good comparing to sonata without 18". Look probably not as good as sonata but the ride is superply quiet since it's a hybrid. Infact the most quiet car I ever ride so far + no vibration at all vs sonata or even my older honda civic fd.

Since replying in sonata thread, it reminded me to recheck my sun roof. I was surprised to find this. I really wonder how it broke off just like that. Probably already broke at the hand of an angry korean man in the assembly line. At first thought it's rubber lining. Now check properly, it's actually plastic that somehow broke in half, resulting in rattling. Rattling sound reduced a bit with some diy but planning to find a piece of plastic that would fit the gap and glued it down.

After a week + battling with the Sonata AC, here are my findings.
I changed the Compressor (recon)
Changed the Condensor (new)
Flushed the AC system
Changed the Valve

Aircond now works perfectly.. sometimes with flaws:
Reduced "coldness" when stuck in major traffic jam
Sometimes could hear either "refrigerant" or "pulley" sound when AC is on (dunno where the exact sound comes from but no leaking of refrigerant)
ONCE. the AC completely shut down and blows hot air. I shut down my car, turn it back on and the AC returns to normal (like how you boot the computer and things go back to normal)

I dont know what else to do. I am lost lol ~ Bring it to workshop to check, cant check anything coz AC is perfectly fine. Hiccups a lot. But overall, I am still loving my YF haha

Aircond is most important in Malaysia for our hot weather. Korean didn't do research before giving us type of aircond? The heater is not needed, why they bother to give heater? No wonder Korean cars failed here. Local companies probably "Yes Man" failed to inform the needs of local market.

Latest news, their sales continue to drop and nobody bothers to look at Korean cars at roadshow in Midvalley. Just me & my friend sitting in 1 of the cars for more than 10 minutes while waiting for another friend to arrive. The sales people, they knew it's hopeless now.

Next year Korean car job intake, if my application rejected again, I'll come with the 3rd wave attack strategy giving free to Japanese competitors.

If Working well, why Sonata YF aircond takes 10 minutes to cool down? Also, local weather so hot. why still have heater? Korean could save cost without the extra hoses for heater. That's main issue over communication between local product planning with Korean HQ.
- Bring in panoramic sunroof, now face problem when car older. Like Citra Caren with sunroof, now old already got rain water leaking.
- panoramic sunroof glass, not cheap to replace once cracked, insurance windscreen coverage premium not cheap.
- sunroof motor if spoiled, start headache from sunlight if not fully shut and cost of electrical repair. When car really old, lots of electrical wiring also worn out, will make repair more difficult.
- big rim, change tyre also expensive.

Subsequently, RV also drop badly because of costly repair news like this, buyers avoid. No wonder RV drop so fast compared to Japanese competitor.

Yapping like no tomorrow. That's why you are being shunned.

Ohhhh ok ok ~~
This Kimchi car second hand year 2011 is actually quite affordable. Price around 65k +/- ~~ Price drop for second hand car is sharp haha~~

I think I will have to send the car to the workshop and ask them to do it haha

Sam Loo doesn't use facts to post, he's no strategist like few users that I have spotted here. Car companies don't hire ace strategist, they appoint only ex-sales and trust only ex-sales. But ever since raptor's gone and I gave free strategies to Japanes brands, they gotten less active since there's no need to attack a brand that is dying and cold no sales anymore.

I am applying for my dream job before I retire with vision to bring up a brand that is never possible like I did in the past directly with 1 Japanese brand model and indirectly with the strategies that I talked to raptor and gang during tea time talk that Korean companies took for free and strategies that I purposely leaked to Japanese companies. My job skill is best in automotive strategist line so why not apply when I am proven?

There's this Korean marketing head that I've been giving free info since I left Japanese brand company and in return I want a permanent job in the company. Immediately kacang lupakan kulit pretend don't know me after the few models hit success. Sure, I took back everything, told all gang members including raptor to stop whatever facts of their own car research report immediately in 2013 and now they starve with no sales, no bonus with retrenchment.

If things kept going like this, their high operating cost would be difficult for them to bear and their companies will shrink back to what it was in 2006. Distributors mostly hire ex-sales with lots of politics inside. Principal direct from Korea sent in 8-10 Korean men while few locals. The locals, they hire fresh grad or experienced staff from automotive line. Every year, these locals that failed to perform will leave and there's vacancy. I'm making them learn. I don't pity them at all. I pity my own income and future. I am doing what you're saying make them beg me next year if don't want to die here and in ASEAN.

my strategies worths nothing because they don't intend to hire me worry that I'll seize the top throne. Kiasu politics from Kiasus working in large companies. My strategies do work and very effective in taking down Korean brands that the Japanese are happily using and claimed as their credits while I'm non-existence.

Check real history, many empires fell whenever they have kiasus running the countries and got the capable warriors and generals out. Korean car companies too facing the same thing when they have kiasus in management care more about their own positions by not letting capable strategists like me in. Now they are making huge losses, unable to put up against Japanese marketing attacks, losing all the sales and facing high daily operating costs. They can't sustain such high cost for long for having large showrooms and assembly plants while sales monthly doing far less than 100, not even 50. They can switch back to small showroom like back then but Koreans would lose face when that happens

how is the fuel consumption of year 2012 sonata.
and what is the major problem of the car

Which is more refined for engine, car compartment, body paint, suspension, braking system, gear box?
