Sedans Hyundai Sonata Hyundai Azera/Sonata Coolant Contamination Problem

I am not sure whether you guys know about this. But in Korea, a number of Sonata and Azera owners have complained to Hyundai that the coolant in their cars are getting contaminated. Some suspect that the coolant is being mixed up with oil or something. Hyundai has denied nothing was wrong till this issue was recently covered by the media recently. The funny thing is that Hyundai said they are not sure what is causing the problem and that they looking for the causes. So far Hyundai has replaced coolant, and in some cases, replaced the radiators of those who have complained vigorously, but the problem remains unfixed, and no official recall is being made. Please check your coolant. I checked mine ('05 Sonata 2.4) last night and mine shows a light murky, brownish ring towards the cap. Although not serious as the one shown below, definitely something is amiss. Whatever the problem may be, I hope Hyundai fixes the problem before the warranty expires in Korea. |

(coolant leaked and also mixed internally with the oil). I just steered her towards a Hyundai Sonata as a replacement. If this starts happening again, she'll leave me! (though I never recommended her Chevy in the 1st place!).

Replying to: amp06 (May 24, 2007 8:50 am) http://blog.naver.com/yohwoni?Redirect=Log&logNo=110017676731 I took a picture of mine just now. It is not murky as the picture shown to a media coverage, but something else is definitely in there. This is quite disturbing. Lucky for you, Hyundai is known to use better quality parts for export vehicle, so your girlfriend's car may be problem free. ">link title |

 Inside look of my coolant. The car is manufactured March '05 with 26,250 miles on it. I am positive I am seeing things that shouldn't be in there. Also, note the black paint or coating peeling. No wonder Hyundai's warranty is relative short in Korea compared to US.

So a few flecks of black paint inside the radiator filler neck are chipped off? How does this make you feel uncomfortable about Hyundai? And what does it have to do with the length of the US verses Korean warranty? Finally, if your picture is of the original coolant  26K miles it is OK. Do you think the countless trips through the entire cooling system over years and miles will leave coolant squeeky clean? Nope,it picks up bits of debris and this is normal and yours looks...normal.

Replying to: targettuning (May 25, 2007 5:36 am) Azera can be bought around $25K in the States. In Korea, the price starts at $40K. A Sontata V6 can be bought less than $20K in the States. In Korea, the price starts at $33K. I bought my 2.4 4cylinder Sonata for $25.6K (Would you buy a 4 cylinder Sonata at this price in the US?). For what I have overpaid, I expect parts to last for some time. Aside from you comforting words regarding the status of my coolant (thank you), the car is only 2 years old with 26K miles on it. Yet, the picture shows it is taken from a 10 year old car. No matter what, I don't think I should have protective paint or whatever peeling off and being mixed with the coolant. Btw, for my overpaid Sonata, warranty for powertrain is 5 years or 37.5K miles. Kinda compares big against the US Hyundai warranty offerings. And US tops that one with 24hrs/7days road service (and the US is about 50 times bigger?). Lastly, when Hyundai luanches completely new products in the US, go ahead and purchase them right away. No need to have concerns like avoid buying first year production. We, Korean buyers, do that for you at least 6 months earlier. Genesis, rear wheel driven sedan, shall be launched first in Korea this coming December. |
