During the last couple of weeks of rain, we have had multiple occasions where our vehicle has lost power steering and our battery light goes on during low speed operation.. there was no deep puddles, just normal rain on streets. In some cases, total stall and others engine screeches and restarts. Without warning. Filed complaint with Hyundai America. Took to dealer. Was advised this was a known problem for 2007-2009 Hyundai Sonatas. And there was no known fix. Had vehicle checked. Advised all splash guards and shields in place. Could not be duplicated at dealership. One service rep at dealership advised his wife has same problem. All belts and pulleys and tension springs ok. We are very disappointed in the response we have received at Hyundai to a "known " safety problem. To be more specific, five(5) occasions have occurred. Told to come back when it rains.

Problem was with the switch on my car. When I turned the car on it made a strange sound for a couple of months, it would only happen once or twice a month. When it became more frequent and began to make the sound a couple of times when I put the car in park, I took my Hyundai back to the car dealer. They claimed it was the starter. My husband and his mechanic said it sounded more like the switch. They wanted to charge almost $500 dollars to fix the problem. My husband bought the switch for about $15 dollars and his mechanic put it on. I have not had any problems since. I do not know if any one else had this problem.

Taking my car for the first oil change since I bought it and the car stalled while in neutral waiting for an oil change. Restarted without a problem. It has also tried to stall while driving several times since, more frequent than before. It's also stalled in stop and go traffic. My check light only comes on for a split second when the car tries to die, but after that, it's just fine. Brought it to 3 dealerships that told me that nothing was wrong with my car. I bought an obdii scanner and found trouble codes P0335 and P0108. Took it to the dealer again and they still couldn't find a code. My car has almost stalled while trying to cross a busy intersection and no one wants to even try to help me.

The incident is similar to NHTSA id# 10508953 which stated there was a grinding noise after starting the car. I experienced the same malfunction but sometimes the grinding doesn't stop until the engine is turned off. It doesn't happen everytime the engine is started but I also had other problems with the ignition switch. A few times the engine started while the key was just turned to the "on" position. After hearing of all the ignition switch problems with GM vehicles, I thought this should be handled by Hyundai as a recall because it is definitely an unsafe situation. I hope the NHTSA will take action on this matter. The vehicle owners should not have to pay for defectively manufactured components no matter how old the vehicle.

Sonata 4-cyl

  • 35,000 miles
Please be advised that I purchased said vehicle new and at around 35000 miles I started to notice that when I slowed down and came to a stop the transmission would jerk on the down shift, which is not normal. On 01-19-2012 I brought my car to the dealer where I purchased from. I was informed that this problem is common and that once my computer is reset it should go away, and there is a service bulletin on that issue. On 03-19-2012 I was having the same issue so the transmission was replaced with factory reconditioned transmission. Now with 74000 mile the car is back for the 5 th time for the same transmission problem. The dealer has my car and I have not heard from the dealer or Hyundai corporation for two weeks. I believe that Hyundai corporation knew the problem existed and neglected to fix the problem other wise a new car with 35000 miles should not have this problem and the mechanics don't know how to remedy the faulty transmission. I am very disappointed with Hyundai and there handling of this problem. I believe the damage has been done, and new software is not going to fix this problem, the bands in the transmission are worn now, the damage has been done. This is just putting a band aid on a serious problem and a manufacturing defect. One does not anticipate any serious problems with a brand new car with only 35000 miles. What good is a 10 year 100.000 mile warranty when you start having these problem at 35000 miles. I have done some research on-line and there are others who have the same problem with same car, I am not the only one.this is a disgrace Hyundai corporation I purchased said vehicle from atlantic Hyundai Inc. Located at 193-205 sunrise highway, West islip NY 11795. I have also contacted Hyundai corporation several times but to no avail.

On October 27 2013, the dash board lights and the back illuminating lights, glove compartment and over head lights went out, I took it to a car repair shop and they changed out the dimmer switch, which kept burning out, smoke has come out of the dash board and it smelled life fire, I pulled over and called the dealer. This is a safety issue I am not able to drive the car at night and I am afraid the care might catch fire. After changing it out 4 times, the mechanic told us to take it to the dealer.we did take the car to the dealer and $700 later they still don't know what the problem it, so I have filed a case with the corporate office, the car has had some electrical problems before, but it has been fixed because they have been recalls. The dealer does not know what to do and they want us to take the car somewhere else. The dealer is no help, they suggested we just buy a new car!!!

Sonata 4-cyl

  • 90,250 miles
I noticed a shuddering at 90,250 miles, while traveling during the winter at around 30-45 mph, but was very intermittent, and would go away. Then on 10/9/2013 at 102,515 miles, from park, the transmission would not engage into reverse or drive. I could hear the transmission shift, but it was not disengaging from park. Per Hyundai service technician, the transmission was "junk" and would need to be replaced. I contacted Hyundai corporate, during which time I was informed they didn't have my information in their system and that in fact there were 2 recalls that they failed to notify me of, and was told that if I allowed the Hyundai service to do the repair right then, that I would be eligible for their policy reimbursement. One of the recalls was an ECM and tcm software update in which symptoms were improper clutching and de-clutching of gears when accelerating and decelerating. That shift quality over time caused undo stress on the gearing causing my failure. The repair was made, I then had to pay upfront, and a week later they've denied my policy reimbursement claim due to fluid being the cause of failure. I then provided them with further documentation showing that their own technician re-used 5 quarts of my original fluid on the repair order, and that I followed the maintenance record that was suggested by their own technicians advice when I purchased the vehicle. Drain and fill every 30,000 miles. The last drain and fill was on June 14, 2013. Hyundai did not provide me with any fluid analysis or specs to support their denial of my policy reimbursement. I saved the agents voicemail of the denial in which she stated due to "color" and that alone, was the reason why the claim was denied.

My ESC off and check engine lights came on. My mechanic indicated it was due to a bad brake light switch as my rear brake lights and cruise control did not work. He replaced the brake light switch but a couple days later the check engine light came back on. The computer listed a different code, stating the brake light switch is not compatible, but the rear brake lights work off and on. Awaiting follow up with my mechanic as he was going to check with Hyundai.

Sonata 6-cyl

  • 50,000 miles


Some times when starting the car with my foot on the brake the rpms go up to about 1200 and then down to 800 rpms. When my foot is removed from the brake the car wants to accelerate and go on its own often. While stoped at a stop sign or stoped with my foot on the brake the car will lurch forward when released, some times spinning the tires. It is progressively getting worse after returning from a 5000 mile trip in June, 2013. The car purchased new and has a automatic transmission with aprox. 65000 miles total on the car. This is a accident waiting to happen and should have a recall.

Around Feb of this year, my car battery died and I got it replaced with a new one. Soon after I started experiencing an additional grinding noise that would occur sometimes after start up. Upon investigation, I was told it was the starter by Hyundai. I took my car to my mechanic however and was told that it was the ignition switch selector, that it had gone bad and that it needed to be replaced. I hope this solves the problem.

  • 55,000 miles
A few days after the ignition cylinder was replaced, the speedometer started malfunctioning. My wife drove the car to work. While the car was running, she noticed the speedometer needle was at zero reading while the car was doing at least 25 miles per hour. She turned around and drove an older car instead. Over the weekend, I drove the Hyundai Sonata around but the speedometer problem did not show up. But the following Monday afternoon, I experienced this speedometer problem first hand. I noticed the car would accelerate from stop with the needle either slightly going up or not at all. I was at least going 25 miles per hour on an expressway. The needle continued to be stuck at zero until I had to apply the brake, and then momentarily, the needle would bounce up between 20-30 mph before going back to zero again.
