2016 Hyundai Accent electrical system 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.”

“The engine failed and requires a full engine replacement. The vehicle is currently at ALM Hyundai West, 1990 Thornton Rd, Lithia Springs, GA 30122, and is available for inspection upon request. Hyundai Motor America has already approved the engine replacement under a goodwill authorization, implicitly confirming the failure is manufacturer-related. The engine failure left the vehicle undrivable, forcing me to operate rental vehicles and arrange multiple tows across three dealerships over nearly two years. An engine failure at under 100,000 miles on a well-maintained vehicle poses a direct safety risk a sudden engine failure while driving at highway or city speeds could result in loss of vehicle control, creating a serious risk of collision for the driver and other road users.Yes. The engine failure has been confirmed by three separate authorized Hyundai dealerships: Ed Voyles Hyundai (Marietta, GA), AutoNation Hyundai (Columbus, GA), and ALM Hyundai West (Lithia Springs, GA). Hyundai Motor America's own goodwill approval of a full engine replacement on July 18, 2025 further confirms the failure.Yes. The vehicle has been inspected by three authorized Hyundai…”

“I was driving up a hill on interstate 8 in California and all of a sudden i heard a bang under the hood and see sparks and flames and my hyundai was on fire right there on the freeway. No clue why.”

“The report does not specify the exact component that failed, but the fire originated under the hood of the 2016 Hyundai Accent. The vehicle and related documentation, including the fire department report, insurance claim, and incident photos, are available for review​. The fire under the hood posed a serious safety risk as it occurred while the vehicle was in motion on a busy highway. Fortunately, the driver evacuated safely, but the incident could have resulted in injury or more severe consequences​ of both driver and other drivers traveling. The problem has not been reproduced or confirmed by a dealer or independent service center. Due to the extent of the damage caused by the fire, it is unlikely that the issue can be reproduced or thoroughly examined. The vehicle has not been inspected by a mechanic since the incident. The incident was inspected by Chesterfield Fire & EMS (Report No. [XXX]), Chesterfield Police Department arrived on the scene, and an insurance claim is in process. About a week prior to the fire, oil indicator light would flash on and off periodically, unusual noise began, and the engine light came on. At the earliest convenience, the car…”

“My 2016 Hyundai accent engine has all of sudden stop working and i have explained to multiple shops and my insurance that i was deployed for a whole year and the car was driving fine and once I came back it just wouldn’t crank. Two Hyundai shops informed me that the engine is locked up but neither shop provided a thorough investigation as to why this has happened. There were two-three major hurricanes in Texas where it was stored while I was deployed in Kuwait and Iraq from march 2023- march 2024 as well as another hurricane in Georgia where i am currently located now which happened September 2024. The engine is locked with no explanation as to how and a Hyundai representative by the name of don who provided the goodwill repair on July 09 2024 and i had it towed to Hyundai in Marietta and they looked and provided the same explanation that the engine is locked and to get it replaced with no detailed reasoning why. My safety has been at risk due to driving across states and town to get this vehicle serviced properly and causing mental anguish and depression as I am not able to get to where I need to go everyday which is causing friction in relationship and I am…”

“The instrumental panel suddenly malfunctioned the abs, airbag, and check engine lights illuminated, and the speedometer dropped to zero. The instrumental panel returned to normal, but the mileage range reset to 0. This was while I was traveling on a highway going 70mph. While it did not cause an accident this time, it was very upsetting. Further it is concerning that there was a recall on the 2014 Hyundai Accent for wiring issues that could cause a fire in the engine also referred to as an intermittent. We had the car inspected and nothing was found to be wrong with the battery/alternator or starter and nothing we could do in regular maintenance to ensure the safety of this vehicle. Note the mileage of this vehicle is 108k which is interesting considering the powertrain warranty was for 100k miles.”
