2017 Hyundai Sonata Complaints

ELECTRICAL SYSTEM,AIR BAGS,STRUCTURE — Filed 01/05/2026

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.

Airbags did not deploy no indicator light came on before nor after I was struck from my driver side front area and yes it is available for inspection upon request. My safety along with my sisters safety was put at risk due to the negligence and cheapness of the dealership I purchased the car from also from there misleading information and improper inspection before selling me the car Car has not been reproduced or confirmed The car was inspected by a third party appraisal company for damages amounts There were no lights on at all before the accident and I am pretty certain that the dealership cleaared the codes before selling me the car

My 2017 Hyundai Sonata Sport Limited 2.4 has a known engine defect causing excessive oil consumption. The vehicle was at an authorized Hyundai dealership for the oil consumption test and had been approved for a new engine replacement. Prior to the repair, I completed $2,300 in maintenance, specifically an oil combustion cleaning and spark plug replacement, which the dealership said was required to perform the oil consumption test. While the vehicle was in the dealership’s custody, it caught fire on 12/19/2025 at World Hyundai Matteson. No one was injured, but the car was destroyed. This occurred while the vehicle was under warranty repair, creating a serious safety risk. I am submitting this complaint to document the fire and the associated safety issue with this engine defect.

I am reporting a serious safety defect involving a vehicle purchased from [XXX] on [XXX]. The vehicle was later involved in a collision that resulted in a total loss. According to the police report, I was not at fault. During this crash, none of the airbags deployed, which indicates a possible defect or prior undisclosed issue with the airbag system. The vehicle was sold with a warranty and was represented as safe and road-ready. The dealership also provided and managed the full-coverage insurance policy. However, the total-loss claim has been delayed and obstructed, and the dealership has not taken responsibility for ensuring the vehicle’s safety or functionality. There is significant concern regarding the condition of the vehicle prior to sale. Records show that Byrider cleared the vehicle’s computer on July 16, 2025, less than a month before purchase. This may have erased important diagnostic information, including any prior airbag-system faults. Clearing the computer in this manner raises questions about whether a known issue was hidden or whether mandatory diagnostic data was removed before the sale. At the time of purchase, I signed an airbag disclosure form in which Byrider stated: •They had “no knowledge of any reason why the airbag system would not operate properly,” and •They “cannot guarantee that the airbag system will deploy in the event of an accident.” Despite this disclosure, the fact that the airbags did not deploy in a crash severe enough to total the vehicle suggests a significant safety defect, potential misrepresentation, or a failure to comply with federal safety requirements. Airbag non-deployment in a total-loss collision indicates a system failure that poses a serious risk to consumers.

Power relay has been replaced several times, air bags did not deploy with either wreck and loss control of steering causing a crash which bent the frame. Hyundai never once contacted me regarding this defective car they replaced motor in because of knock sensor and im lucky to be alive. On one of the accidents in February there was an error message that popped up right before I had the wreck and it was an error message wrong with the cars transmission system or something like that I had the dealership who said there was no codes on that car and I had my own personal mechanic who had codes pop up on that car that the dealership hid

STEERING — Filed 07/08/2022

While driving my 2017 Sonata on a winding backroad my power steering suddenly locked up without warning, and I was unable to turn the vehicle left or right. Prior to this incident there were no warning or check engine lights lit indicating any type of issue with my car, and my power steering was operating normally. I hit, and jumped a curb striking a rock wall attempting to turn slightly left to keep myself in my lane, and on the road damaging the right passenger side rim and fender. After coming to a stop I noticed there were two warning lights that had activated. I immediately called my local Hyundai dealer (Imperial Hyundai of Milford Massachusetts) informing them of what had happened, and scheduled a service appointment to have this issue diagnosed. I was informed by the dealership that Hyundai is having issues with their electric assist steering motor, and computer module which controls the steering assist motor. Had this been my wife or son this would have definitely turned out differently, because I'm over 240lbs and could barely get the steering wheel to turn at all prior to hitting the curb. After shutting off the car, and then restarting it repeatedly for approx 30 minutes suddenly the service lights went out, and the vehicle started operating normally again. My appointment at the Hyundai dealer is on July 13, 2022. I was told Hyundai has extended the warranty on parts associated with the steering system, but they wouldn't tell me which parts are covered or not covered. That is the least of my concerns, because like I said had I not been the driver, or if this had happened at highway speed this could have been tragic. It's a serious safety issue
