Hyundai Sonata Problems

Engine -- Verified

On the 2.7L V6 and 2.4L 4 Cylinder, a defective exhaust gas recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.

Engine -- Verified

If you experience excessive engine noise on startup (after the engine has been turned off for several hours) that lasts for more than five or six seconds, turn off the engine and check that the engine oil level is correct. If the oil level is correct, the noise may be caused by the timing chain tensioner. Hyundai has an improved tensioner to correct this problem.

Drive Train -- Verified

Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct. Also, make sure the computer that controls the transmission has the most up-to-date adaptive programming information. When servicing these transmissions be sure to use fluid approved by Hyundai.

Engine -- Verified

Problems with the accelerator pedal position switch may cause the Check Engine Light to illuminate; an improved switch is available to fix this problem.

Electrical & Lights -- Verified

    Parking lights not turning off intermittently or all the time. The common problem is with the cabin fuse box.  Complete replacement of the assembly is necessary to fix the problem.

Hyundai Sonata Reviews

I purchased a 2009 Sonata GLS new in 2009. It now has over 90,000 miles on it and it is unquestionably the most reliable car I have ever owned. Handles nicely, economical to drive, fantastic warranty,dealer service departments very customer friendly and besides nornmal servicing has required nothing. Since I purchased my Hyundai my son has purchased an Elantra and my mother-in-law and my father-in-law have each purchased Sonatas. In addition, I have a new 2013 Sonata Limited on order and will be taking delivery within the month. Needless to say, I am very sold on the Hyundai line.

i love this car.. it has taken me places i have never been before...i hit 200,000 miles with only two bad batteries... the auto store replaced both of them cause they are under warranty...then i had a bad o2 sensor.. easy fix... but now my timing belt has broken. so we have driven the value out of it.. but its always got that special place in our life...at one point it was the only thing we could depend on.. so as for other hyundai owners i am a happy one...

Been a great car so far. I get about 26-30 mpg. Best mpg was 34 on a 260 mile trip. Only problem so far has been the airbag red light came on at about 70,000 miles, and it was under a recall. I love how it handles.

i have this lovly car and i adore it so much thx for korean people but plz dont eat the brain of monky alive like chinese people

This car is a nightmare for me. I brought this car new and the car is now going on 8 years old and it has so many problems. I took it to my mechanic the other day and he informs me that I need: rear hub bearings, a rack, injectors and IAC (whatever that is). Also, my timing belt needs replacing. My car has approx. 120,000. I should have brought a Nissan like my family always did. When I had my Nissan, it was still running at 15 years old. It really did not have any problems. I never had to replace the rear hub bearings, a rack, injectors and IAC or any major parts. I would not suggest to anyone to buy a Hyundai.
