A very loud, clicking sound coming from underneath the hood. Car would not accelarate and eventually stalled on a very busy highway. I was unable to get the car started and had to be towed. The engine needed replaced and I had to acquire a rental car for a week. I was then informed of the recall after my car was taken to a repair shop. The engine could not be repaired so another rebuilt had to be installed. Reimbursement for costs is expected due to recall.

We purchased this 2011 sonota used from the fox dealership in grand rapids, mi. The car started with odd engine sounds on 3/3/15 while driving city & local and then stalled out. Was able to restart & 2 days later the car stalled again. After multiple tries it did restart and we got it to a shop a few blocks away. After that it would not start. The shop said the engine was frozen. After calling fox huyndai to see if they would help us, as we just bought the car in Sept 2013, they would not help and only offered $4000 to install a refab motor. The shop it was at said $4500 for a new motor and neither could guarantee that the same problem wouldn't arrise. We ended up scraping out the car after 4 days of getting quotes and trying to determine our best option. The car was sold to peddle via peddle.com. (docs attached) peddle sent a West Michigan company out to pick up the car from us on 3/9 or 3/10/15.

I received a notice for safety recall for my car which I just bought 3 months ago from Hyundai dealership in tampa. My car is making noise from the engine as I drive. I called today to the dealership and they stated that I would have to drop the car off. I said that's fine as long as I can get a loaner so I can drive to my work. The person (jeffery martinez) refused stating that they don't have a loaner car right now. I said you are giving me appointment for Thursday and how can you tell me that the loaner is not available for Thursday? he just kept refusing and so I asked to speak to a manager and he just tells me that the manager will call me and hangs up the phone. I called this morning and talked to a person name karen and she told me that loaner cars are only for people who pay for services and that I would have to speak to an advisor for it. That person never called me! I am not happy with the service that I received from this dealership. This is not my fault that the engine is making noise due to recall and if I have to get it fixed then I should be able to get a loaner complimentary until my car is fixed.

In August, 2015 my engine seized on my while driving; there were no warning lights nor any warning that anything was wrong with the car. Thankfully I was driving 20 mph on a local resideintial street with no cars behind me so I was not injured. Had I been on the highway I would have been severely injured if not killed due the immediacy of the car shutting down dead in its tracks. A local Hyundai dealership installed a brand new engine and the car was returned to me. I found out a couple of weeks after receiving my car back that Hyundai was putting out a recall for all 2011/2012 Sonatas yet I found it interesting that I had not received any paperwork. On October 11, 2015 my car caught on fire while I was driving. The engine seized, I lost my brakes and my ability to steer the vehicle. Thankfully I was travelling up hill so the car stopped on its own while it sat there and burned and more thankfully, all three passengers were able to get out of the car unharmed. The initial inspection confirmed that it was an engine fire while further investigation is underway. After this incident I began researching the internet to find out if there had been other incidents to find out that there had been, that this had been going on for some time with engines seizing as well as catching fire. On Friday October 30th I received a recall notice but with no clear instructions...just a "sit back and wait to be contacted with a next step". I do not feel that Hyundai is doing enough to notify owners of the potential dangers involved. The engines seizing is enough to cause a potential death not to mention the engines catching on fire. More needs to be done to remedy this in a more expeditious fashion. I am notifying every Agency possible in hopes of avoiding anyone else from experiencing what I have - twice!

During cold weather, the 2.0 turbo Sonata engine will cut power to the car and go into a "limp" mode if an over boost code (usually P0605 & P2110 ), is triggered. This causes an unsafe situation as there is very little power available to get out of the way or can cause a rear vehicle crash. There have been a couple times where this has happened on 0 degree days or even at 30 degrees. This will happen at any speed if the boost pressure is exceeded and makes for a very dangerous situation. The ECU should not be cutting power or fuel, it should be reducing the boost to compensate for temperature. The only way to restore the power to the engine, is to shut the car off and restart.....codes will still be active but the power will restore itself.

In August 2013 I purchase said car. A month later, I noticed the engine was consuming/burning oil excessively, approx. 1 qt./500 miles. Took it in to glendora Hyundai, they topped it off...my impression of them, no big thing to them. I tried to tell them something, but to no avail. I have emails of my concerns to glendora Hyundai, etc. On July 1 through 9, 2015, I took a road trip in the Sonata to vacation in dallas, tx. On the way back on early Thursday, July 9, the engine started to ping and sputter. Pulled over and assessed engine failure. I was 35 miles away from odessa, I fortunate to get there safe. Struggling at 45 mph off highway 20, I was able to pull in at 4:00am into the odessa Hyundai. I waited that Friday morning until it opened at 7:00am. On Friday, odessa Hyundai was able to determine engine failure. Needless to say, stuck in odessa, I had to get hotel for a one night stay and a car rental to return home while the repairs on my Sonata where completed. A month later, on August 7, I was able to return to odessa and retrieve my car. I paid out of pocket $2,957.10 to get my car back. However, it seems that my car suffered engine failure through this recall that created heart ship and a dreadful ending to a seemingly successful vacation. More importantly, I tried early in August/2012 to avoid all this. Nevertheless, I have correspondence on my behalf to back up my claim. Your consideration on this claim for reimbursement will be greatly appreciated. Thanks!
