2021 Hyundai Sonata 4 DR FWD

Recall on my vehicle states there is still no remedy after one month.

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.

The contact owns a 2021 Hyundai Sonata. The contact stated that while traveling at highway speeds, a tiny pebble hit his windshield which caused a minor ding on the middle of the driver’s side windshield. Over time, the ding spread from the driver’s side to the lane assist sensor located in the middle of the windshield. The contact stated that the crack spread vertically and horizontally across his windshield. He stated that the crack had obstructed his vision while driving at various speeds. The dealer was initially notified of the failure and informed him that he had to have the vehicle repaired by a recommended third party. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was 23,000.

The contact owns a 2021 Hyundai Sonata. The contact stated that while the vehicle was at an independent mechanic for an oil change, the mechanic diagnosed the vehicle with transmission fluid leaking from the engine. The mechanic informed the contact that the transmission fluid leakage was flammable. The dealer was made aware of the failure but informed the contact that they were backed up with other vehicles and could not diagnose the vehicle for approximately three weeks. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was 5,600.

2021 Sonata N LINE NOT EQUIPPED WITH AUTO WIPERS WIPERS INTERMITTENTLY COME ON BY ITSELF WHILE DRIVING. IT HAS COME ON MULTIPLE TIMES WHEN USING MY TURN SIGNAL. WIPES ONCE THEN GOES OFF. HAS ALSO COME ON ONCE WITHOUT THE USE OF THE TURN SIGNAL. SWIPED 3 TO 4 TIMES AND THEN WENT OFF

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.

WE LEASE A 2021 SONATA SEL EQUIPPED WITH AIR BAG SYSTEM FEATURING AN OCS IN THE RIGHT FRONT SEAT. THE PURPOSE OF THE OCS IS TO DISABLE RIGHT PASSENGER SEAT FRONT AIR BAG WHEN IT DETECTS TA CHILD RESTRAINT SYSTEM OR SMALL CHILD IN THE RIGHT FRONT SEAT. RIGHT FRONT AIR BAG IS DISABLED TO PREVENT INJURIES TO A CHILD FROM A RIGHT FRONT AIR BAG INFLATION DURING A CRASH. MY WIFE IS ABOUT 4'10" TALL AND WEIGHS 135#. WHEN SEATED IN PASSENGER SEAT, SHE REQUIRES A CUSHION TO RAISE HER SO SHE CAN SEE OVER DASHBOARD AND OUT SIDE WINDOW. OUR SONATA IS EQUIPPED WITH MANUAL PASSENGER SEAT THAT IS RAISED TO HIGHEST POSITION. PROBLEM IS THAT WHEN SHE USES CUSHION, THE OCS LIGHT STAYS ON INDICATING THAT AIR BAGS ARE DEACTIVATED AND WOULD NOT DEPLOY IN AN ACCIDENT WHICH COULD CAUSE AN EXTREME SAFETY HAZARD TO MY WIFE. WE TOOK CAR TO DEALER SERVICE CENTER TWICE, AND WE CALLED HYUNDAI USA CUSTOMER SERVICE - BOTH SAID NOTHING COULD BE DONE. SMALL ADULTS LIKE MY WIFE SHOULD BE ABLE TO BYPASS THE OCS USING A SHUNT OR BYPASS SWITCH. WE FEED THIS IS A SERIOUS SAFETY HAZARD. EARLIER SONATA MODELS WERE RECALLED FOR THIS ISSUE.

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.

PANORAMIC SUNROOF EXPLOSION. HAPPENED ON OPEN HIGHWAY ROAD WITH NO CAR IN NEAR VICINITY OR SIGN OF ANY KIND OF DEBRIS HITTING THE VEHICLE.
