SERVICE BRAKES, ENGINE
Without warning, the Sonata stalls while in motion: - the brake pedal goes close to the floor, - the CHECK BRAKE light goes on, - the emergency brake audio alarm and light go on, - the READY light between the fuel and temperature gauges blinks. I have to pull over and turn the car off / on in order to get the car functional again. The speed of the car doesn't seem to matter. This has occurred 11 times over the past year, including 6 times today (7/22/2021) within a span of 15 min, while at speeds between 30- 60 mph. I took the car to the dealer (initially on 6/22/2021). There were no diagnostic error codes and they could not reproduce the problem. I called Hyundai, both on 6/22/2021 and today, to file a report. Hyundai did not provide any insights into the issue. Online, I have read of others having this same issue with Sonatas. Some believe a faulty power brake booster to be the cause.

UNKNOWN OR OTHER
I was on the on ramp of the freeway with the closest vehicle several hundred yards in front and no vehicles behind or on the side of me when my sunroof "exploded". Fortunately the curtain was drawn so no glass poured in the vehicle, but when I pulled over half the sunroof was gone and the remainder in shredded. I do no believe anything struck the vehicle.

AIR BAGS
Headlights have burnt out 4 times in 1 year w/install, break/tail lights have burnt out 6 times in 1 year w/ install. Cruise control isn't staying set and airbag light is on unknown reason after OBD scan. Break lights have burnt thru the connection piece, causing damage, overpower from the wiring harness has caused over load of power which caused lights to burn out and even burst. Multiple drivers with similar problems, airbag may still deploy for no reason or not deploy at all. Cruise control malfunction possibly due to airbag issues, but may also be from faulty wiring throughout the vehicle and ultimately into the sterring console. Computer or motherboard may also now have damages cause by over amped volts of electricity without a serge protecter. Possibility of electrical damages, caused by overload from power supply and directed throught the vehicle may have cause exponential damages to electrical in the sonata. Causing a serious safety concern and hazard. Exterior lighting requires new wiring harnesses and connection pieces as well as new casing from over amp overload, resulting in overheating and bulb combustion damages. New airbag assembly is probable and reset of mother board with upgraded features and completely new wiring with serge protection is necessary.

ENGINE
Engine replaced under recall. “New” engine has low pressure after install. Car does not accelerate as needed. Check engine light and oil light come on. Took back to dealership several times, told an engine flush would fix problem, problem not fixed, told a tune up would fix problem, problem not fixed. Engine still has lower pressure. Dealership did testing requested by Hyundai corporation. Engine light still illuminated, engine still has low pressure, car still does not accelerate as needed. Have talked to several other people with Hyundai’s that have had engine replaced under recall, having same problems.

SEATS
I JUST PURCHASED MY 2011 HYUNDAI SONATA FROM A PREVIOUS OWNER. SEVERAL RECALLS REPAIRS HAVE BEEN PERFORMED ON THE VEHICLE PRIOR TO MY PURCHASE. THE ISSUE I'M REPORTING - THE DRIVER'S SIDE SEAT IS STUCK IN THE RECLINE POSITION AND THE SEAT WILL NOT GO BACK UP OR MOVE FORWARD TO INCLINE POSITION. I'M DRIVING WITH NO BACK SUPPORT. THE OTHER DRIVER'S POWER SEAT CONTROLS WORK EXCEPT FOR THE ONE THAT RAISES THE BACK OF THE SEAT. IN THE EVENT OF A CRASH, THE SEAT COULD INADVERTENTLY RECLINE AND INCREASE THE RISK OF A VERY SERIOUS INJURY OR FATALITY. MORE POWER SEAT FAILURES HAVE BEEN REPORTED ON THE HYUNDAI FORUM: HTTPS://WWW.HYUNDAI-FORUMS.COM/THREADS/POWER-SEAT-FAILURE-HELP-NEEDED.107030/
