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!

I was driving my 2012 Sonata on the interstate at normal speeds, when I heard a bang and then some clicking coming from the engine. The engine light came on, so I pulled over quickly. When I got out of the vehicle, white smoke was coming from under the hood. When I got out, there was a small fire on the left side of the engine. I called 911 when my quick attempt to put the fire out with a bottle of water was useless. I was advised by 911 to get clear of the car and so I watched as my car with less then 35,000 miles burned. The vehicle was a total loss. There had been no issues with the car up until this fire. It totally burned in about 15 minutes.

My children were driving and stopped at a light. When the light changed, my son pressed the accelerator and the car didn't move. It shut off. When he attempted to start it, nothing happened. No lights ever came on on the dashboard. Had the car towed to pohanka Hyundai in capital heights, md and was told that the engine was locked up and that it was not covered under warranty because I was the second owner and it would cost me $5774, .88 to have it replaced with a rebuilt engine. I also purchased an additional warranty which I thought was bumper to bumper when I purchased the car in January 2014.

In October 2014, I had an incident where my car completely shut down while driving straight on the freeway (please see attached Hyundai paperwork) without warning. My car was at the Hyundai dealer in North palm beach for 3 1/2 business days before finding out my car was "fixed" and ready to go. The first two consecutive days my car was there, I was called by the service manager rob and was told that "the engine was completely locked up, and they had to run a series of diagnostic tests prior to replacing the engine" which was under warranty (under 60,000 miles at the time). However, I was called on day 3 where rob stated that my "engine was running smoothly and no diagnostic codes were showing up." My paperwork from Hyundai states that the only problem was the need to tighten the battery terminals and recharge the battery. Checking the battery is one of the first things a car mechanic checks when a car does not start, so obviously there was a more significant undiagnosed problem in this case that was swept under the rug so to speak. A little over a month and approximately 1000 miles later, my car stalled out completely on the freeway in similar fashion (only this time, there was intermittent engine shaking prior to the car shutting down). However, I was in martin county when I broke down and my car was towed to the Hyundai dealer in stuart per progressive car insurance towing policy. I had previously completed all my services at the dealer except the last oil change. I am appalled that the dealer did not take into consideration the recent car problems and placed the cause 100% on the local oil change facility. An engine does not lock up completely and get fixed by tightening terminals and recharging the battery. Obviously, there was a severe problem with the engine both the first and second time I went to the dealer.

My husband purchased the car in Feb 2015. We took a trip in the car to NY in Sept 2015. Only 7months of ownership. While driving on a city street, all the lights blinked on. The car started to slow down, we heard a loud knocking noise. We turned the car off, turned it back on again. The car just stalled. Luckily we didn't get into an accident. We towed it to the nearest Hyundai dealer, who told us we will have to pay for another engine. They couldn't even assist us with a rental. So we are paying out of pocket for a rental car. Luckily this recall was set. Hopefully we can get reimbursed for this rental car.
