Was parked in bank parking lot. Started engine, placed car in reverse and car accelerated at a very high rate of speed. (like I was in a drag race!!) applied brakes, which did not slow the vehicle down. Did not stop until I ran into a parked car. Whole incident took just seconds. Car had been in for regular service at the dealers on [xxx]. now has 16,597 miles on vehicle. Car to be serviced at rachels collision, 720 S nova road, daytona beach, fl on Monday [xxx]. if I had not ran into a parked car, I would have entered [xxx] in daytona beach shores, fl which was crowded with motorcycles.... Friday noon during bike week. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)
The Battery dies randomly (like I have to open the car with they physical key to access the car dead) there isn't a pattern. I have taken it to the dealership and they can't diagnose it because they cant replicate the issue and say nothing is wrong. Sometimes the car dies while I'm INSIDE and just having lunch while the car is off.
Integrated 12V battery dies with no warning and requires manual keyed process to get in to the vehicle. Once inside, the battery reset button needs to be pressed to have the solar battery start the vehicles electric system. After a few minutes the engine takes over to start charging the battery. I have had the battery die 3 times on the 2021 Hyundai Sonata Hybrid in one week. Other postings online indicate others owners are having issues with the battery also with one owner loosing power while operating the vehicle on the freeway. After safely coasting the vehicle to the shoulder, the reset battery button restarted the electrical system for the car. Possibly an issue with the 12V battery implementation with the solar battery?
Antifreeze is coming out of the exhaust. Heater is only blowing cold air. Repair shop said it is a common problem with the Hyundai hybrids. Was told I had to take it back to the dealership. The y repair shop said this is very common and is wondering why a recall has not been issued by the NTHSB. Dealership has been unresponsive.
1. Vehicle Speed Control 2. I was in a friend's driveway with the car in drive with auto hold activated. Car lunged forward and not able to stop it. Ran into a garage door did substantial damage to home owners property. I guess we were lucky the door took the impact. 3. I took to dealer today to report and have appointment to have looked at on January 8th. They have no previous report of this happening. 4. I have contacted my insurance company, but they are just filing a claim. 5. I was talking to my guest and was not looking at the dashboard, but I saw no warning message after the fact.

We received a letter back in Dec 2021 about a recall for our windshield that Hyundai was aware of but there was no fix available. It states that if in a crash it could be real bad because the adhesive on the windshield. However i don't think it should take almost 5 months for a serious recall like this.
I have had my 2021 Hyundai Sonata LES for less than a year and am already having problems with the front windshield. There is -??air nose-?? coming through the windshield when I drive above 55 MPH. There has been recalls for this problem on some 2020-2021 Hyundai vehicles. The 2021 Sonata is one of them. However, when I look up to see if there is any recalls with my VIN number, it shows no recalls. I know my windshield is defective or wasn-??t properly installed.
Hello The car shut off on the freeway while driving. The display lit up light a Xmas tree including the forward collision warning. I though this was an isolated incident. It has happened now numerous times. The car even braked on its own then shut off while turning in the middle of a busy intersection. There are several reports of very similar symptoms on Edmonds under reviews. This car is dangerous. I have contacted Hyundai twice now.
On August 23rd, 2021, I was on a business trip between High Point, NC and Greenville, SC. I was operating my own vehicle as the mode of transport. Upon arrival in Greenville, the car began behaving strangely. The transmission was not shifting at typical intervals, at times racing the engine at low speeds. After restarting the vehicle, there was a brief return to normal. Then the vehicle reported a "Check Engine" light and the transmission stopped functioning entirely. Due to capacity issues, I was unable to utilize a local dealership. I used AAA to tow the vehicle to Fort Mill Hyundai in Fort Mill, SC, where it remains to this day. The vehicle threw a P0868 code, which is supposedly a generic error relating to an electrical problem in the transmission.
On Wednesday, October 6th, I was driving full speed (65mph) on a major highway. Multiple lights on the dashboard came on. The LCD display screen for music, apps, etc. went black. More lights came on and others went off on the dash display. I let off the accelerator and steered the car. The fuel efficiency was wilding jumping back and forth. Soon enough, all the lights went back off, but the mileage gauge (fuel efficiency) continued to jump wildly. The brakes seemed to respond differently- almost as if there was a delay between me pressing the brake and the brakes catching. When I needed to accelerate, the car seemed to be having trouble switching between the electric and gas motors. I was able to drive to a safe location and shut the car off. This was terrifying, as the car's computer system or electrical system clearly failed, even if temporarily. The car was taken to the dealership immediately. The car's mileage is under 4, 500 miles and was purchased in February 2021. There have been other small issues but never anything like this. The display screen has gone black before a few times, my cell phone won't connect (even manually and it's properly connected, working seamlessly other times). In those cases, I shut the care off and restarted it to fix the issue. However, this new incident is terrifying and unacceptable. Including photos taken that show impossible fuel efficiency as only evidence I could safely capture.
The contact owns a 2021 Hyundai Sonata. The contact stated that after driving out of the garage and parking in the driveway with the engine idling and remote smart parking assist feature activated, 6 minutes later the vehicle suddenly began to slowly roll forward into the garage area making contact with a second vehicle that was parked in the garage before crashing into the back of the garage wall and stopping. During the incident, no injuries were reported, and no police report was filed. The vehicle was taken to the local dealer who was unable the duplicate the failure. The manufacturer was also notified of the failure. The approximate failure mileage was 1,400.
Excessive wind noise is coming from the driver side window when speeds are over 55mph+. A lot of other owners on the forums are experiencing the same problem.
Seems to be an issue with the wireless apple car play. Regardless if the vehicle is in motion or not it loses connectivity. While driving this cause you to take your eyes off the road as messages appear on their infotainment system. Calls are dropped, navigation stops so while you are looking at the messages you're not paying attention to the road. Apple is aware but has not resolved it. Hyundai is aware but have not resolved it. The internet is loaded with issues for this situation. Not sure if this is something you can assist with but I'm assuming at some point their will be accidents because when this happens you can't use the hands free option as it also stops working.
