2009 Hyundai Sonata Problems

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.

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.

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

2009 Hyundai Sonata Recalls (Recent)

Suspension & Steering, August 12, 2013

RepairPal Expert Overview:

The rear suspension is the attaching point for the control arms and other rear suspension components. Road salt and water can accumulate in and around the rear crossmember causing it to rust. Excessive rust could cause one or both rear control arms to separate from the crossmember resulting in a sudden change in vehicle handling, increasing the risk of a crash. Dealers will inspect the rear crossmember and repair or replace it as necessary to correct this concern.

2009 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.

My problem started very early with this 2009 Sonota that I bought brand new; First the dealer overfilled the engine with OIL; I was shocked and another Hyundai dealer let the OIL out and shamed the dealer for that. Also this car doesnt take over filling of the oil easy. It can cause bad damage to the engine valves. But the worst happened when at 20,000 thousand miles the Transaxle started Bumping real bad at 20 MPH going down in speed. The force from third gear to first was so strong it would stop the wheels into a skid and the force threw me under the seatbelt near the gas and brake pedal. I have contacted the Dept. of Justice on this car because Hyundai lied about the issues and would not fix anyones car and running from the problem. Its major and happening over the U.S. but Hyundai said" They have no other complaints but my car is the only one doing that" Edmunds.com and many other sites including You Tube claims overloads of Transaxle problems that could bancrupt Hyundai. Also the Car took off like the Toyotas did a few years ago while I was in Washington D.C. Arlington Cemetery. Yes, for no reason in the parking garage the car starting going up , up and up in speed while I had both feet on the brakes trying to stop the car and almost hit a concrete pillar. The Arlington gaurd security unbottoned their gun holsters ready to fire their weapons . They didnt know what I was going to do when I finally got the Car stopped. This story has been reported to the DOJ in Washington hoping to get them aware of this dangerous and consumer based problem that could cause people to file Bancrupt against this Car and maybe start a minor recession. They really need to look at this Transaxle problem and maybe the Cruise control or throttle body issue before People get killed. I think I had a mild Heart attack while the car went out of control. My issue is if they cant warrant the car 100,000 miles like they claim then dont make the claim in the U.S. Thats all.

I have owned mostly GM autos through out my many years of sales. I have a 2009 Hyundai Sonata and I'm almost at 100,000 miles. I have only had to take it in for 1 minor repair since I purchased my car ( n/c to me). This is one of the most reliable cars I have owned. Very Happy with the car.

I remove the ignition switch i turn the key to got out the switch now i can not got the new switch in the key will not go to off .

I had a problem with low idle almost like it wanted to stall. I took it to the dealer repeatedly and they finally repaired it. It runs great again. Just replaced my original set of Kuhmo tires with Goodyear Assurance. Tires are nice but after repeatedly getting them balanced, Sears just informed me that 3 of the 4 dealer installed chrome wheels are slightly bent which is why I no longer get a smooth ride. I will be contacting the dealer to find out why this is....the parts department at Columbia Hyundai was less than helpful and stated that they no longer carry those wheels...I wonder why... I wonder if they will offer a solution. My car is a 2009 Hyundai Sonata...I have not hit any potholes that would have caused this...I hope I can find a reasonable solution.
