2009 Hyundai Sonata Problems

Noise on Startup Due to Failing Timing Chain Tensioner

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.

Peeling paint

The problem Im having with my 2007 Sonata is the paint is peeling off like nail polish. And rusting on the hood near the wiper blades. Squiking front end during cold weather.

2009 Hyundai Sonata Recalls

Rust 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.

I bought my 2009 Hyundai Sonata in 2010. It was a great car and never had any issues with it. Have driven it cross country round trip 3 times.

Now I have to pay out ...
