Owner reports
Selected complaints filed with NHTSA by 2017 Hyundai Sonata owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2017 Hyundai Sonata. The contact stated after opening the trunk, it failed to close. The contact tied the trunk closed with a rope. The contact received notification of NHTSA Campaign Number: 21V619000 (LATCHES/LOCKS/LINKAGES) however, the part to do the recall was unavailable. The vehicle was taken to the local dealer who stated the parts were not available. The dealer was able to close the trunk and informed the contact not to open the trunk. The contact stated the manufacturer exceeded a reasonable amount of time for the recall repair. The manufacturer was not notified. The approximate failure mileage was 133,000. Vin tool confirms parts not available.
I was involved in a severe motor vehicle collision in a 2017 Hyundai Sonata. The airbags failed to deploy during the crash. I sustained serious injuries and was transported from the scene by EMS. This vehicle has known safety recalls, and I believe the airbag non-deployment may indicate a safety defect.
The Hyundai was started, feint knocking was heard. Progressed louder as vehicle accelerated, engine then stalled, check engine light and oil pressure light turned on and traction control disengaged as the vehicle erupted into a rolling blaze
Ever since I have had my car there has been a wind sound like some this is dragging under my car! Been to dealership multiple times and they tell me that's how these cars sound! Now oil is disappearing right after and oil change! They say my oil pan bolts were stripped out! Well the Hyundai dealership is the only people that have done my oil changes! Tried to charge me for that! I get an engine diagnosis check done and they tell me nothing is wrong with my car! Before I could make it home engine light was on! Took it back now they saying engine manifold! Want to charge me for that! Now car won't go over 20 mph! White car paint has chipped from the front roof and hood of car! Driving I see multiple white vehicles with paint chipped in the same areas of the vehicle! Call corporate they know about the the issue. They want to spot paint the car! …
The car's paint is peeling all over. The roof was repainted in 2018, the hood and side door in 2024 and now the the roof supports on each side and trunk are peeling . While driving a big piece of white paint flew to my windshield blocking the driver's view. It stuck under the wipers when used to remove it. Hyundai is aware and has recalled the paint but delays fix and then fixes in tiny areas so that you have to continue coming back for repainting. Now they do not want to pay for repairs stating the recall expired. It expired because of their delay and not painting the entire car. Hyundai should paint the entire car when there is a paint defect.
Car has 41,019 miles. The paint is peeling off the car. This issue seems to be widespread and effects both Kia & Hyundai. Mine 1st appeared Jan. 31, 2023 on the driver's side hood above the headlight. Paint color is W8, Quartz White Pearl (this color seems to have the most problems). Hyundai was notified immediately, 02-01-2023, but have gotten no response. There is a Facebook page concerning the issue (KIA and Hyundai Defective Paint Class Action Group) and you can see how widespread the problem is. The paint is obviously defective or Hyundai did something wrong in applying it. This simply is not a coincidence and Hyundai should be accountable!
The vehicle's dashboard continuously displays a "hood open" warning even though the hood is fully closed and securely latched. The hood has been physically inspected and confirmed to be closed, yet the warning persists. The issue appears to be related to a faulty hood latch sensor or switch, which is part of the hood latch assembly. The warning is inaccurate and does not reflect the actual condition of the hood. I am requesting that NHTSA review this issue for potential investigation, as it may represent a defect in the hood latch sensor system on the 2017 Hyundai Sonata that could affect multiple vehicles and pose a safety risk.
The rear passenger door will not open from the inside or the outside. This is a safety hazard in that an occupant cannot get out of the car in an emergency. There was no warning lamps, messages or other symptoms of the problem prior to the failure. In doing research about this issue, the problem is well documented on Hyundai internet forums since 2021 so there is no reason this shouldn't already be considered a safety recall. The dealer was contacted and advised that since this is not showing as a manufacturer issue or a NHTSA safety issue, there is nothing they can do.
1. Sunroof frame detached from car due to defective adhesive. (Antena tailfin also detached from car years earlier because of defective adhesive). Because of this the frame was bent causing the sunroof to disengage from car . 2. Sunroof disengaging while on Interstate could have causes an accident or harmed person in car. A recall was placed on 2016 HYUNDAI Sonatas due to sunroof. 3. Unknown 4. HYUNDAI hired an engineering firm. The firm ( which was paid by HYUNDAI) found in favor of HYUNDAI. 5. Unknown
The cap on the shark fin antenna came loose in normal service and cannot be secured. If this part were to fly off at highway speeds it would pose a safety issue to following vehicles since it becomes a projectile capable of causing significant damage. This problem is similar to that documented in KIA TSB SA272 which Hyundai does not recognize, although both manufacturers share similar component designs.
