2016 Hyundai Accent problems

ABS module electrical fault and fire. On the evening before the fire, the vehicle displayed ABS and ESC warning lights with diagnostic fault code C2402 (motor electrical fault). A continuous buzzing/vibrating noise came from under the hood near the engine compartment and persisted for several minutes even after the engine was shut off and key removed. Disconnecting the negative battery terminal immediately stopped the noise. The next morning, approximately 12 hours later, the vehicle caught fire in the engine bay near the ABS module. The fire was extinguished manually. The vehicle was towed to a dealer. The ABS module and surrounding wiring show fire damage and are available for inspection. This defect poses a serious fire risk.

I brought my vehicle to Victorville Hyundai to address the official manufacturer safety warranty extension, Campaign Z01, which covers a defective passenger side Occupant Classification System (OCS) airbag sensor. My vehicle currently has 129,000 miles. The dealership and the service manager refused to perform the necessary safety diagnostic or inspection unless I signed a pre-authorization contract agreeing to pay a out-of-pocket fee of $219. The manager explicitly stated that this fee would be charged if they found that the sensor was contaminated with "outside water or dust." While I confirmed that the vehicle has never sustained any liquid spills or water intrusion, the vehicle is driven in the High Desert area and naturally contains standard environmental dust due to its age and mileage. By inserting the word "dust" into a mandatory pre-authorization agreement, the dealership is creating an intentional, deceptive financial loophole to deny a corporate safety warranty and avoid repairing a critical restraint system component. Because I refused to sign this predatory waiver, the dealership refused to service my vehicle's airbag defect, leaving a critical safety issue unresolved

Engine failure on a vehicle under 100,000 miles creates a risk of sudden loss of power while driving. A failing catalytic converter & coil packs can cause overheating and potential fire risk. These components were either pre-existing manufacturer defects or were damaged during the engine replacement process at Auto Nation Columbus (Columbus, GA), neither of which was disclosed to me as the owner.

The Emergency brake light, ABS light, and esc light all come on while driving & speedometer goes to 0. The speedometer also stops tracking mileage when these lights come on. This used to happen on & off, but now it’s almost permanent. Hundreds are reporting the same exact issue online, but mechanics cannot figure out what the problem is. Me and countless others have taken the vehicle to mechanics multiple times with no resolve and thousands of dollars worth of diagnostics that are incorrect and don’t resolve the issue. It is dangerous because we don’t know how fast we’re going, and we don’t know if your abs, emergency brakes, & esc are all working properly. This issue is impacting Hyundai Accents years 2015, 2016, & 2017 based on the multiple threads & posts online. I think it’s related to electrical issues too because my windshield wipers & blinkers will randomly malfunction while this is happening. A random online user said that it is a “SMART Junction Box” issue that needs to be replaced. Please look into this and issue a recall because thousands of people are spending thousands of hard-earned dollars with no resolve.
