2009 Hyundai Sonata ProblemsParking lights don't turn off
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.
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.
2009 Hyundai Sonata Questionsgrowling noise in front end (1 answer)
growling noise in front end while driving and noise does not change when accelerating or decelerating or when turning to the right or turning to the left and changes with rpms
I just had the transmission fluid replaced and there is no diagnostic code registering. But there is a definite clunk on decelerating.
My 2009 Hyundai Sonata has a flashing check engine light, mildly shakes when in park and when I accelerate it starts to shake a little bit more.
2009 Hyundai Sonata RecallsRust Concern with Rear Suspension
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.
