Summary

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.

Summary

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.

Summary

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.

Summary

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.

Summary

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.
