Hyundai Azera/Sonata Coolant Contamination Problem
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.
