1/2 mile after starting my vehicle and driving approx 30 mph, my car shuttered and shook. Pulled over and it seemed to fix itself so I continued 23 miles to work. Was approx 39 degrees according to car dashboard. Leaving work 9 hours later, I drove approx 1.5 miles in stop and go traffic, speed no higher than 25-30 mph, crossed over rr tracks and the car shuttered and then shut off completely rolling to a stop. Threw on my hazards and the screen indicated I should put it in park and restart. The battery light and master indicator light came on. Car restarted and the lights disappeared. Went straight to Hyundai dealer. They attempted a 17 mile road test the next day after the car sat overnight and it did not repeat the issue. Nothing was stored in the computer system from when the lights came on. They have no explanation. Oil was changed and took car back at 5pm the day after the issue took place. Drove 24 miles to work today and it did not repeat yet.

The remotes to my vehicle are defective they slide off of the valet key without the release button being pushed. Since the vehicle does not use a key to start it, will be unable to use my vehicle if the remote continues to fall apart. One of they remotes was already lost due to this malfunction and the other is wrapped in taped.

My Sonata has started stalling and shutting down without warning. The first time it happed was Dec 12th. I just finished accelerating from about 35mph to 60mph. There the vehicle made a loud thump and the engine shut down. Seconds later I lost power steering, dash lights, and headlights. The car restarted without issue. The same problem happened on Dec. 16th while traveling at a constant 30mph. I experienced the same symptoms as before, except the vehicle did not shake or create a loud noise before shutting down. Mileage was at 75980. Temperature was in the 20's. I took the car do the dealership and they could not find anything wrong or recreate the problem. The third time this has happened was Dec 29th. I was traveling at 20mph and coasting to a stoplight. It was 19 deg outside and the mileage was around 76800. So far the car has not shut off when the weather is above freezing. Lower temps might be contributing to the problem but not likely to be the primary cause. In all cases the car was at operating temp and was running for more then 30 min. It has not yet shut off while accelerating. Only maintaining speed or coasting. About a two months ago the dealer did a software update on the vehicle due to a claimed recall. The issue started about 2-3 weeks later this is definitely a safety issue since it happens without warning. I did find some other complaints similar to this while searching.

There is a continual fluttering noise from the engine compartment which was not heard when this vehicle was first purchased. When I brought it to the Hyundai dealer to check what the noise is, the service rep, tiffany, heard the noise also when I started my engine & let it run. However, when service was completed, I was told that the serviceperson could not replicate it. This is continual and doesn't stop. I was told the engine was checked and there are no recalls for a noise of this type being issued. As a matter of fact, after they checked this, the noise was even louder and I have to keep the radio on to block it out. This is not normal. This occurs on whatever type of road I'm on and quiets down when I'm at a red light while the vehicle isn't in motion. Turning doesn't stop it. I drive on highways & city streets.

Drove Sonata on North lake blvd going East from dealership after getting car serviced. Stopped at congress for red light. Noticed engine surging and tach at above 3000 RPM. Pressed hard on service brake. After a few minutes engine idled back down to normal at 750 RPM idle speed. Car has not duplicated above experience to date. This incident happened on 11/13/17

I was beginning to accelerate at a stoplight when it turned green, on a major city street, when the engine stopped without warning. The power remained, the dashboard remained lit, the radio on, climate controls on, phone remained connected to bluetooth, but the engine would not restart for 5 minutes or so. When I finally got it restarted I drove it straight home; the next morning, it restarted just fine, but I was reluctant to drive it and had it towed to the dealer. They have kept it and driven it for 150 miles since then, and nothing has happened. No error codes have shown up on diagnostics.

7 speed dual clutch transmission. Car shakes loses power and stalls causing hugh issues and unsafe driving conditions. Hyundai does nothing for the repair had my car at the dealer 5 times already with 20,000 miles on it. Car is unsafe and no one is doing anything about it but taking my money. I lose power from a stop in traffic on the highway or stop signs. The hesitation is so bad my whole car shakes. I am not the only one with this issue I found thousands of others online & a current lawsuit in California. These models need to be recalled asap its unfair we have to pay for a car that is about undrivable.

The car is two years old, at less than 10,600 miles the battery has to be replaced, which did not follow under any manufacturer warranty (replacing cost me $195 at 25% discount). The car trim is a limited, Sonata, however a mouse was able to brake into the engine and ate the wire hardness, ( which also I had to paid to be fixed) my concern is that there are many safety plastic protector for wire, and they may cause fire if not detected on time. The major problem I had experience with the car is that, within this two year that I driven it, the engine shut down while I was in the vehicle stationary standing at a red light no once, not twice but a thee times, the last time my family was in the car, including my granddaughter. I am really afraid to drive the car on the highways, at this point I don't know what to do, I called the main depot of Hyundai, I told the problem they set up another appointment with me this coming Friday. Do I have to wait the vehicle's engine to stop again to file for a lemon law. Please I need advice before this turns ugly and may cause serious damage for passenger or passerby if the engine fail at the wrong time. Last time (after the engine stops for the second time) Hyundai tried to fixed the problem by updating the software. But it seems that this solution did not work. Because the engine stops for a third time.

The air intake hose melted from the heat of the turbo. The symptom of this is a whoosing sound and degraded acceleration. You cannot drive the car with this issue as it can suck in a foreign object into the turbo vanes and bend them, causing permanent damage that may not be covered under warranty. You could imagine what a simple pebble would do at the rpms that the turbo spins at. My Hyundai Sonata only has 14,740 miles on it.

I purchased new '15 Sonata, my 8th one, but I have not nothing but problems with it. This dealership did all maintenance & repairs & had car a total of 7 times for the same complaint of the car 'bucking, ' like it is hard to shift into the next gear.I was told it was a computer part & it had been replaced, yet the problem continued, other times I was told there nothing could be detected as wrong. My 7th trip, the dealership kept it for 6-7 weeks when they determined the transmission clutch was defective, then they 'lost' the new transmission, before finally fixed it. I drive 100 miles daily to & from work am fearful that something would be wrong. I was almost rear ended by a far away 18 wheeler when the car would not forward. I reported all of this to the dealership. I requested to speak with general manager at least 3 times & was always told he was out, the last time I saw him leave after saying he was not there. So, after the transmission was 'fixed' in February. I called corporate & was told this is the way this vehicle drives as it has a semi-automatic transmission. I am driving a rental with same engine & does not behave like my mine. Within a few days, the car began stalling when trying to excel and the 'check engine light' came on. On the interstate, we slowed down and again it would not go forward. I brought it to another dealership & it has been in the shop for two weeks (March 25th) & they cannot figure out the problem. Corporate offered me $500 in 'free' service due to it the problems. I do not think that is compensation. Corp has agreed to buy car back approx. 2-3 wks ago due to continued problems. I was told the entire process would take 6-8 weeks. I have emailed/called since it is in the shop to expedite the process without response.

I read an article on a website stating that a class action suit was filed against Hyundai related to its blue link system. The article stated that if you allow your blue subscription to be expired for more than one year, Hyundai would possibly permanently deactivate your blue link system. My subscription had expired, so I contacted Hyundai and reactivated my subscription for one year for $99. I was concerned that if the blue link system was permanently deactivated in my car, the resale value of my car would go down. I was not aware of this issue until I read the article last evening.

The car has issues with the transmission shifting erratically. There is a very loud chattering coming from the engine. It is getting progressively worse. The panoramic sunroof is constantly creaking whenever driving on uneven pavement. The car has been in the shop for check engine issues since it was three months old all related to the intake manifold and vcm. And the vehicle stalls randomly and does not set off and check engine lights. Dealerships keep saying no issue found. Rotors have warped.

On three different occasions the dash flashed "check TPMS" meaning check air in the tires. On all 3 occasions the car would not go into gear.the next occasion the check TPMS came on so I put air in the tires and drove around the corner to reset the tire pressure monitor (computer). Upon coming around the corner to park the car the check TPMS warning came on again the car powered down and I coasted to park. The next morning I called the dealership to have the car checked I was told from jared that the technician did a software update and that " he thinks, maybe, might have fixed the problem. At this point I did not pick up the car because they could not guarantee the car had been fixed and that it will not die while driving around Hyundai service department said they were not sure because they could not duplicate the problem I had with the car. I left the car there contacted hyndai corporate where they opened a case #9327831.. they in turn had a fast team working on my car and they are not sure if the car is fixed or not because they could not duplicate the same problem. The have had my car for a month now still have not been able to find out what the problem is. I was told it does not fall under lemon law unless the car does the same thing again. But I do not know if the car is fixed 100% it only has 12,513 miles on it. Car would not go into drive the gear shift would not move to where I could drive the car.
