2014 Hyundai Elantra vehicle speed control problems

“Vehicle Information: 2014 Hyundai Elantra SE Sedan, 4-Cylinder, 6-Speed Automatic, FWD Build Location: USA-Built Version (Montgomery, AL - VIN '5NP') Ownership: Second owner, purchased Certified Pre-Owned (CPO) from the Hyundai of New Port Richey dealer (Florida) in March 2016. Vehicle is owned outright. Mileage: 128,638 Approximate Date Incident Noticed: October 1, 2025 DESCRIPTION OF CRITICAL SAFETY DEFECT & WARRANTY REJECTION I am reporting a failure of the clock spring assembly, which compromises critical safety features and poses an unreasonable risk, especially since this vehicle regularly transports passengers, including children. My VIN was rejected by the Hyundai TXXA Clock Spring Extended Warranty validator despite exhibiting the exact failures covered by the campaign. Safety Failures: Airbag (SRS): Warning light is constantly illuminated; driver-side airbag is disabled and will not deploy, endangering the driver and front passenger. Horn: Completely inoperable, eliminating a vital safety communication feature required to warn other drivers. Cruise Control: Buttons on the steering wheel are non-functional. These failures are caused by a broken…”

“This has occurred three separate times, but this report explains what happened during the most recent occurrence. I was driving at 40 mph. The car in front of me hit their brakes, so I lightly tapped my brakes to slow down. When I tapped the gas pedal, the car would not increase speed. The check engine light, oil light, and battery light each turned on simultaneously. The car then stalled completely, but the lights remained on and the car didn’t lose power. I hit the brakes (which were now hard to push down), hit my emergency flashes so that the car behind me would pass me, pulled over to the side of the road, and then I turned off the car. When I turned the car back on, 30 seconds later, all of the lights were off and the car started with no issue.”

“My car is only at 46000 miles.SinceI'm purchase from dealer it has given me the same issues of RPMs shooting up &speedometer going out of control the car wont go past 20mph & jerks back & forth, tyrning off while driving & has had a b"bad" drive since purchase.

“The piston rings do not seal leading to increased oil consumption and very low oil. My safety was put at risk because when I pulled out into traffic that was going at a high speed I could not accelerate. There was no warning or indication that this was going on prior to this incident. Yes this has been confirmed by a Hyundai dealership and the component was inspected. There was no warning sign before this incident.”

“While driving over the last month, the car shuts off with no warning. There are no check engine or other lights that come on once it shuts down. There does not appear to be any consistency in the occurences, sometimes while idling, sometimes while driving 40 mph. Up until recently, the car would restart once I put it in neutral, but it now does not restart right away.”

“I was driving the vehicle normally down the highway. When I exited the highway, I came to a stop light and made a complete stop at which point the engine stalled. I restarted the vehicle, the check engine light appeared, but I couldn’t get it to register any RPMs and I was left stranded in a busy intersection until help arrived.”
