While driving my Sonata an error appeared on my dashboard stating 'hybrid system warning! safely stop and do not drive. Check brakes." When this occurs the gas pedal goes to the floor and the brakes grinds my tires. U can hear a loud chiming like sound coming from the car. I'm reading this issue with a number of Sonata hybrid.

When braking and turning, in forward or reverse, engine intermittently revs and propels car. Throwing it into park somewhat slows it down, but I have hit a car I reverse, and almost ran into a building two weeks ago - stopped by heavy shrubs leaving the whole front end wrecked. Mechanic and Hyundai have not been able to replicate, but it happens only intermittently, maybe 6 times in two years. In parking lots, driveway or drive through food window.

Sun roof shattered while driving. Nothing hit the sunroof to cause this.

I was on the interstate during torrential downpour, my car's check engine light started flashing and I couldn't accelerate above 2,000 RPM or go over 60 mph. It was very dangerous. I took the car to the dealership to be repaired. After 3 days I picked the car up, and they said they replaced the knock sensor and the car was fixed. Since then this has happened 3 more times. Car is currently in the shop. I started researching on my own, and I read that the knock sensor was an update Hyundai added after the recall of the engines in these cars. This knock sensor is actually protecting my car (and me) by putting it in 'limp mode' because it senses something dangerous in the engine. I have contacted Hyundai Consumer Affairs to inform them I am afraid to drive the car because this has happened so many times and clearly is't fixed, and I'm sure it has to do with the recalls they have and engine fires. They've done nothing. Last time I went to get the car the manager at the dealership said that many people were having issues, but Hyundai doesn't allow them to actually fix the problem. They have to do work-around fixes instead of the actual repairs needed. The manger said he predicts that "there will be a class action lawsuit because of Hyundai not doing anything to actually fix this engine issue". I don't know who to turn to, but I' am afraid to drive the car. I don't want to be driving down the road and the engine catch fire. I'm currently pregnant and it has been very stressful dealing with this issue. I fear the dealership will disable the knock sensor so that it stops putting the engine on limp mode and then I will have a fire. I also fear that the knock sensor may not work correctly next time and the engine may catch fire. I need the engine fixed. I hope by submitting this complaint it will help get this engine problem solved for me and consumers.

The (mil) malfunction indicator light came on and my car just suddenly stopped running when I pulled up to a stop sign, when I braked for stop sign to make a left turn, while driving, leaving walmart shopping center.

Driving in light rain on normal pavement St louis county. Approached stop sign at end of steep hill. Applied brakes lightly and well in advance but car was not stopping. Realized that engine had stopped so nothing was working. Car began shaking violently as if brakes were trying to grab. Finally came to a stop in the middle of intersection - fortunately nobody was in front of us are attempting to cross intersection in other direction. Car was completely dead. Tried to restart but nothing. Had to move car so tried to start again - starter did not crank at all, but suddenly engine was running as if it had never stopped and all power was restored. Drove immediately to dealer thinking it was something to do with engine recall. Was able to get to the dealership about 5 miles away with no incident. After 3 days of being at dealer we were told that something in the brake fluid "module" had broken lose and brake fluid leaked into wire harness causing extreme corrosion. They believe the engine never actually stopped running, but rather the electrical signal was momentarily interrupted due to the corrosion. It was going to be a $5000 fix. We did not have car repaired. Dealership said they would send it to auction. This car must to be pulled off the road as it is a hazard to anyone who purchases it, even "as is". reported to Consumer Affairs at Hyundai on 11/6/19. Spoke to a representative 11/14/19 and was told car would be taken out of service. I am reporting here to insure that it is indeed taken out of service. We could have been killed or seriously injured. Wife drives about 35 miles per day and it could have easily happened while she was driving to work.

2014 Hyundai Sonata was dropped off to nearby Hyundai dealership for scheduled recall appointment campaigns 180, 953, 160, 162, and 946 on 04/24/2019. Dealership communicated to me all recall inspections were made, and no further repairs or replacements to the car was needed at approximately 11:30am on 04/24/2019. Car was then picked up through the sales department at my earliest convenience on 04/25/2019 at approximately 7:00pm. After driving 9 miles on a 55mph street, my car lost immediate acceleration/power causing the speed to reduce without warning, and without brake lights activated (witness to this is the individual who drove me to the dealership to pick up the car, and was currently driving behind me at the time of the incident). After immediate loss of acceleration/power (the car was moving at 55mph), the check engine light began blinking. The car was immediately moved off the road, and a burning smell was detected after removing myself from the vehicle. As the service department was unavailable, the sales department from who gave me my car we're unable to properly assist me with receiving a tow back to the dealership, and provide me with a loaner car for the cars inability to be driven. At approximately 8:50pm, a tow arrived to take the vehicle back to Hyundai's dealership in which the recall inspections and campaigns were performed. Dealership approved a rental for the following day, yet unavailable/unable to be approved until the service department re-opened. Currently, the dealership has me in a rental car through enterprise, covering the cost except for $1 a day (which is to be paid by me). More so, as this is not my car, an additional coverage charge of $9 per day was required to insure me coverage in the event the rental is involved in an unexpected accident. As of 04/28/2019, I am waiting to hear an update from the dealership about my car.

I just bought this car about 2 months ago, I'm quite surprised to see a air bag light on a car that had less then 100,000 miles from the dealership that was certified preowned.

As I was driving on the road made a right turn it sound like something pop so when I put my car in reverse or drive it makes a loud sound plus it wouldnt move but when I put it in park it moved like it was in neutral...

- Philadelphia, PA, USA

I went into the dealership to have my engine recall replaced. My car would not start the following day I got my car back after the repairs. The engine caused my starter to go out. The dealership would not honor fixing it so I had to pay for those charges which I think should have been fixed by Hyundai interstate.

- Monroe, LA, USA

When I stopped my car and put in park I turned the key in the ignition to the lock/off position but the key would not turn to lock/off go in the off position. So, the key was stuck in the ignition. I turned the car on and shifted to drive than back to park and turned the car off to remove the key however it was still stuck. I did this several times because I had the same problem two week prior and this method worked. I was by a locksmith that I could was to unhook the battery until I could take it to the dealership.

Takata recall - car is blowing out smoke - in 700 miles it has lost 2 quarts of oil, it has under 50K miles, it is covered under 2 different recalls thru Hyundai but they refuse to replace the engine, when you try to accelerate - the car will hesitate and then all of sudden blow smoke out the back - so much that you think the car is going to catch on fire, we have had it in the dealership 3 times already - contacted them other times in between. Now when trying to accelerate at just 1 RPM smoke comes out the back car starts shaking like its going to stall out check enginge light comes on - a few seconds later big cloud of smoke comes out back and car will then move leaving trails of smoke behind. Check engine light went off. Hyundai said unless the check engine light is on - it wont matter. They just want us to do a oil consumption test - the engine is making a knocking noise. Hyundai has heard it too. We leave so much smoke that we cant see a car behind us. It can barely make it to accelerate on the highway. 6/21/17 - massey Hyundai hagerstown 7/18/17 - massey Hyundai hagerstown 8/28/17 - massey Hyundai hagerstown Hyundai case #10553414 - they know about it! we have had it towed to the shop 2 times now.

Every three to five days when push to start vehicle it will not turn on. All lights/electronics come on but the vehicle just will not start. When towed to the dealer or tow driver arrives the car starts again. Have had the battery tested and tested bad, replaced but the problem continues. Hyundai says "cannot duplicate the problem" and sends me on my way with no resolution. Now dealer as well as Hyundai regional office refuse to answer the phone or return any of my messages. Has happened at least if not more than 15 times.
