The auto on several, sporadic occasions had an acceleration problem, while sitting still in traffic. While sitting still in traffic, the rpms wold start to increase, going to 6000 rpms before I geared it back down and shut the engine off. I took it too the dealer on several occasions, they kept it couple of days each time, they told me, they could find nothing wrong, and go ahead and drive it, if it happened again, bring it back, sending me away in a unsafe vehicle. The last time, date mentioned above, a service technician test drove my car, the acceleration problem occurred, and he totaled out my vehicle. I was not notified until 2 days later that my vehicle had been in a accident. I was told, it happened the night before, I was notified on sept 13, 2013, that would have the accident occurring on sept. 12,2013, when in fact it occurred on sept. 11, 2013. I have searched and found on several occasions that this vehicle, did indeed, have acceleration problems, which the dealer had informed me, had never happened before. The vehicle, should have been diagnosed and the problem fixed, the first time, instead of the dealership, sending me away each time in a unsafe vehicle. Very unethical of the dealer, for telling lies about the car,and, and the correct date the incident occurred, not notifying me for 2 days, that it occurred, and. Not fixing the problem, as should have been expected of them, the first time it occurred, and sending me away each time in a unsafe vehicle. This issue happened on September 11, 2013.

#6 - Engine And Engine Cooling problem of the 2011 Hyundai Sonata
The vehicle involved is a 2011 Hyundai Sonata. I got into vehicle to go to work & it failed to start. Illumination light kept blinking telling me to push in brakes, but I was pushing in brake peddle. I just bought this car used, 35 days ago, have not had any issues until today. Contacted Hyundai dealer to find out that I am not covered under warranty, because I am not he original owner. Which I was told vehicle was covered until 100,000 miles from used dealer. Have an appointment to get vehicle inspected & keeping fingers crossed that the issue has something to do with one of the many recent recalls. The failure date was Thursday, August 29, 2013.
#7 - Engine And Engine Cooling problem of the 2011 Hyundai Sonata
The vehicle involved was a 2011 Hyundai Sonata. Car would not start when I pressed the brake and start button. Tried several times and nothing. Brake was very hard and after 10 minutes I gave up and drove my truck. This is about the 4th time this has happened. I will take to dealer. From reading the blogs sounds like the brake light switch will have to be replaced. The failure date was Tuesday, August 6, 2013.
#8 - Engine And Engine Cooling problem of the 2008 Hyundai Sonata
The vehicle involved is a 2008 Hyundai Sonata. I was driving my car and, according to my mechanic, the crank rod came loose. I bought this vehicle used so the Hyundai 100,000 mile warranty will not cover it. I have done routine oil changes and up to this point had no real problem with the vehicle. It is disappointing to say the least as I have had this vehicle for about four years and purchased it based on the idea that Hyundai's are supposed to be reliable vehicles. I had hoped that Hyundai would have done something to help remedy the situation but at this point they have not, which is also disappointing. In the future I will not be purchasing a Hyundai. This issue happened on 06/07/13.
#9 - Engine And Engine Cooling problem of the 2011 Hyundai Sonata
I leased this Hyundai Sonata in 2011 brand new and after 3000 miles began having issues with the car not starting by using the start button. The workaround was to place your foot on the brake and hold down the push button start for 1 minute and the engine would start. This was intermittent. It would happen frequently and then suddenly be better for long periods of time. Finally at 18000 miles went to start the car and everything was dead. It drove ok the day before (not like a car who's battery was bad). The car is being towed to the nearest dealership where I happened to purchase it. In addition to the start issue and the completely dying part (and it was not able to be charged by ordinary means) the car also has a low tire pressure warning that stays on regardless of how much or how little air is in the tire. That remained for 4 months and now seems to be staying off. The car also drifts to the left when driven (it has done this since I purchased it). I had several recalls fixed early on at the dealership, but it did not correct the drifting issue. There is also a rattle in the dash which began at 16,000 miles. The back door handle (behind the driver's seat) handle was stuck in an outward position and the door would not open. It finally opened one day and now the handle is back in place, but a small black piece hangs down from the handle. I have read on the internet several complaints that are the same or similar as all of my issues. This issue happened on Sunday, April 21, 2013.
#10 - Engine And Engine Cooling problem of the 2011 Hyundai Sonata
I bought a 2011 Hyundai Sonata in March of 2010 brand new. I have had problems with the tires had to be replaced after year two, and when they were being replaced they said that the air valve on the tire was corroded when I went to Hyundai to get the part replaced they said that it wasn't corroded it was broke off because there wan't a cap on it and it got wet. So, they said that I had to buy a new one, and they would send it up under the warranty and I would be refunded that did not happen. After that my push start would not start when I pushed it. I would have to push it about three times and then it would finally start. I took it to Hyundai, and had it replaced not under warranty any more is what they told me. So I paid the 287. 00 for it. After I got it home and went into grab something came back out and it did it again. Took it back to gateway Hyundai in richmond to have it fixed and they said it needed a nother starter. I didn't have to pay for the part but I was going to have to pay for the labor. Nope didn't get it fixed. I would just start it three times instead. Then I had to replace the brakes last year 2012 because it wore only on one side, and now the engine blew a rod. They claimed that it was because of not having enough oil in it, but then told me I had a quart to much of oil. Now really does that make any sense? this is absolutely ridiculous. Then they told me I could trade it in for a new Hyundai but would have to put $5000. 00 down on it which is convienantly the amount they quoted me to have my engine fixed because they said it wasn't under warranty because I hadn't kept all my receipts for oil changes for the past three years. This engine and engine cooling issue occurred Feb. 25, 2013.
#11 - Engine And Engine Cooling problem of the 2007 Hyundai Sonata
The vehicle was a 2007 Hyundai Sonata. Had just had my car smog checked, oil checked, tires rotated and began my drive from san diego CA. To san antonio TX. I get to ozona TX I hear a clinking in my engine. I pull off the freeway and the car dies, the car behind me almost hit me my car is towed to the Hyundai dealership in san angelo the following Monday, and the mechanics said it was low on oil and the engine had seized. I could not afford to have an engine put it in at the time, as it is an expensive engine costing 5, -$7,000. 00. I had the car towed to san antonio TX where by a mechanic who said it was low on oil (had just had oil changed @ Hyundai). He added more oil. The people at Hyundai said they changed the oil and got the car to unseize and turn on but it was knocking. My car was later taken to am aamco, where the mechanics looked at it and found parts falling off it as they removed the oil pan. They called Hyundai, because another can just like mine came in that day with the exact same problem. The person at Hyundai said there is now a service bulletin out on the car but it has not been voluntarily recalled as of yet, because not enough people have stepped forward n filed a formal complaint. They do know that there is a problem with the way the filter soaks up the oil in the engine. It happens with no warning. No indicator lights came on in my car. . . No engine light, no oil light, no overheating or smoke or anything. Was running fine, and died. In this horrific place ive been put in, being stranded in a small texas town for a weekend, then another, and having to pay for rental cars, towing, multiple mechanics, I have learned alot about the car. The engine (according to Hyundai)is expensive because they didnt make very many. It costs more than the v-6!! many people have had the same exact problem with their cars, its all over message boards online and known among the salvage yards, machinists etc. It was Saturday, March 16, 2013 when this engine and engine cooling issue happened.

#12 - Engine And Engine Cooling problem of the 2009 Hyundai Sonata
The car is a 2009 Hyundai Sonata. While slowing at around 25-30 mph the car would "jerk" forcefully like a sudden stop. This happened every day. It would improve as it warmed up. I took it to the dealership and was given excuses (they told me that the transmission needed flushed-at my expense, my driving habits, etc). Finally after several trips to the service department, they admitted the issue. The transmission was eventually replaced after they "reset" and flushed the original transmission. It seemed to get better. I still feel the "jerk" in the downshift, but it is not as bad as it was. I mentioned this to the dealership and they told me that it was going to cost $100. 00 just for them to "look at it" even though it is still under warranty. This problem occurred on Sep. 25, 2010.

#13 - Engine And Engine Cooling problem of the 2011 Hyundai Sonata
The car was a 2011 Hyundai Sonata. The vehicle identification number (VIN) of this Hyundai Sonata is 5NPEC4AB2B_. Brake pedal sensor failure resulted in a car that wouldn't start. The key-less entry depends on the brake pedal being depressed, otherwise the ignition will not turn over. Under normal operation when the driver is trying to start the car, the key must be inside the vehicle, the driver must depress the brake pedal and then press the ignition button. The car normally turns over. In this situation all systems function as if the car does not know the brake peddle is being depressed. The battery has full charge, all accessories function normally, but the ignition will not turn over. Because there is no way to manually start the car, the car is rendered completely useless. It was Sunday, March 31, 2013 when this engine and engine cooling issue happened.

#15 - Engine And Engine Cooling problem of the 2011 Hyundai Sonata
The car involved is a 2011 Hyundai Sonata. I have had my vehicle in for service 5 times for the same issue, it would not start. The first 3 times a sensor switch was replaced. The fourth time I was told my battery was the issue so I got a new battery. Today was the fifth time and the service dept indicated they could not find anything wrong but they went ahead and replaced the sensor switch again. I am not happy, I feel that I cannot depend on my vehicle. I am planning an out of town trip for thanksgiving and have resorted to renting a vehicle because I am paranoid about being stranded on the road with this issue. I paid alot of money for this vehicle and this just is not right. I am considering trading it in for a vehicle that starts the traditional way (with a key). This issue happened on Wednesday, Nov. 14, 2012.
#16 - Engine And Engine Cooling problem of the 2012 Hyundai Sonata

#17 - Engine And Engine Cooling problem of the 2013 Hyundai Sonata
The VIN of this vehicle was 5NPEB4ACDH_. Purchased 2013 Hyundai Sonata GLS at streetboro ohio Hyundai dealer new in mid June 2012. Vehicle seemed ok but at about 1500 miles idle became rough particularly at idle in drive at lights and stops. Took in to dealer and was told after 4 days in shop that problem was familiar to the dealer and an engineer was being called in to figure out the solution as no codes were stored in computer. I left the dealer after being told car is within Hyundai specs but was running strange. The dealer seems to be avoiding doing anything to admit there is a issue and refused to allow a service tech to ride along with me to experience the problem. They also refused to let my salesman go in a newer model with me to see if any other vehicles had same issues. I wrote to Hyundai corporate and was given a list of other dealers to go to. As the problem has begun to get worse the idle will now rev and then decelerate the vehicle when coasting and I can imagine what this braking action will cause the vehicle to do as the weather becomes worse and snow appears. This seems to be a growing problem with the Hyundai models from the recent Hyundai forums posts. It was Fri., Aug. 10, 2012 when this engine and engine cooling issue happened.
#18 - Engine And Engine Cooling problem of the 2012 Hyundai Sonata
The vehicle is a 2012 Hyundai Sonata. Repair attempts 5; first attempt at date of incident. Driving on level three lane divided highway when the vehicle suddenly stops accelerating and exhibits a no power condition where only electrical is working. I apply acceleration up past 5000 rpm and no response. Past 6000 rpm and vehicle suddenly kicks in and out of complete shock I'm forced to pull over in nearby plaza to contact nearest dealer (in southern California @ this time, original dealer in las vegas centennial Hyundai). Allen Hyundai service technician agrees to keep it overnight to duplicate issue. He puts in writing next day "three no power conditions. " after blaming it on the turbo and adjusting electrical sensors, I continued experiencing same problem, different places. Original dealer for some reason fails to duplicate and leaves me hopeless. No offer to trade car or take it back. Now stuck in purgatory between corporate and a malfunctioning vehicle. 2012 new off the lot se with 2. 0 t. This engine and engine cooling issue occurred 02/03/2012.

The vehicle having this issue was a 2011 Hyundai Sonata. The vehicle identification number (VIN) of the car was 5NPEB4AC4B_. 3x the driver window button is inoperable. Would turn off car and then it would again work.

I noticed each time the the gear console does not light up. The car actually does not go into gear. Each time I have turned off the ignition and restarted it and it works fine.

#22 - Engine And Engine Cooling problem of the 2006 Hyundai Sonata
My car is a 2006 Hyundai Sonata and last night my cars' headlights dim or shut off momentarily, the fan speed seems to drop for a second also but never shuts completely off. I noticed last night my tachometer would only go to a 1 at the lowest. It would go higher as I drove but never back down towards a 0 or 1. You could feel the harsh vibration as I sat at a stoplight while it rested at 1. I also noticed that it feels like the trans is slipping or something as I take off or try to turn. This is the first time I have ever experienced this with this car. This is extremely dangerous!! what if the gas pedal sticks or the lights go out while driving??? I have 2 small children and you bet I would sue or my family would on my behalf if anything happened to us as a result of Hyundai not issuing some kind of recall. Please address this issue ASAP as to avoid any future problems that could have been corrected by a simple recall. The failure date was 01/18/12.

#23 - Engine And Engine Cooling problem of the 2011 Hyundai Sonata
The car involved is a 2011 Hyundai Sonata. At 5:15 pm on 8/22/11, I got into my car to go work and it would not start. It was very hot and I was sweating trying to get the car started. I tried several times but the car would not start. I called the dealership and I got no assistance. The screen on the dash-board read "press the brakes" which I did like I have done in the past. I gave up and contacted a friend to take me to work. Later, that night it did start but would not start again so I assumed it was the battery. I called roadside service and they arrived 5:30 am in the morning to jump start the car (not the battery). It gets better, a lady that lives in my area was walking her dog, who has a black Sonata 2011 told me that her Sonata would not start and she just got her vehicle back. She told me what was wrong with my car. I called the dealership again while I was waiting on a tow truck and explained how this could have been a bad situation if I was stranded with my mother in the car who just had surgery to remove cancer. I explained that I needed my car repaired immediately because I needed to transport my mother and I was concern the car would stop working again. The Hyundai representative stated he would have it fixed in 15 minutes and he also indicated that there has been a few Sonatas that the "sensor" under the break pedal has gone bad. The salesperson that sold the vehicle to me stated the same that the "sensor" goes bad. Eight (8) months of ownership and the lady with the black Sonata had her car less. The tow truck driver said he has picked up a couple of Sonatas that would not start. This issue happened on Aug. 22, 2011.

Would not turn off until I depressed the start/stop button for approx 5 seconds. Eventually the car powered on again. This happened twice in the last 48 hours. The car is currently at the dealer.

My car suddenly started losing engine power to the point where my car would not move after the stop light turned green, leaving me stuck in the middle of a huge intersection with people almost hitting me. After restarting my car, it finally started to move, but repeated the same instance at the next stop light. This is a serious safety issue. I had to have my car towed to the dealership because I was not going to risk my safety and life.

#28 - Engine And Engine Cooling problem of the 2011 Hyundai Sonata
The car involved was a 2011 Hyundai Sonata. While driving on the freeway I experienced a large jolt which resulted in an unexpected shift in the transmission gear where my speed of approx. 65 mph at 2000 rpm dropped to 45 mph at approx 3800 rpm. Had the freeway traffic not been light at the time, this could have caused an accident. Although the transmission indicator showed it was in "d", the gear was probably closer to 2nd gear. I pulled off the freeway and shifted from d to r to n to p, however it seemed that it was locked in 2nd gear. I managed to drive it in that gear to the local Hyundai dealer. However once the engine was shutoff and restarted, the transmission was back in its normal gear and they were not able to duplicate that event. In addition, according to the service representative, the computer showed no problems. After doing a search on the internet, it appears this has happened to others. This issue happened on Oct. 14, 2011.

#33 - Engine And Engine Cooling problem of the 2011 Hyundai Sonata
The car was a 2011 Hyundai Sonata. The vehicle identification number (VIN) of the car was 5NPEC4AC8B_. 2011 Sonata limited with Smart key fob has failed to start a minimum of 7 times in the last 60 days. It appears that sometimes the car does not recognize the Smart key and this doesn't change if the Smart key is inserted into the center console Smart key holder. The batteries have been replaced in the key fob and this does not resolve the problem. When attempting to start the car the computer simply states to depress the brake pedal and push the start button, which I've been doing. The brake pedal often feels hard as a rock almost like it's locked. The normal diagnostic lights and fuel guage does operate but the car doesn't start. I've waited as long as 1/2 hour attempting and re-attempting to start the vehicle. After it starts, the car may work perfectly fine for the next few trips until the problem reappears. This is a worrisome occurence since there is no way to override the Smart key fob by inserting an actual key to start the vehicle. Drivers may become stuck at any time. It was Aug. 2, 2011 when this engine and engine cooling issue happened.
