2023 Hyundai Elantra SEL. Car has been slow to start this week. When I depress the brake pedal and push to start, it will start then shut off in the middle of starting then I have to try again or it will sputter then fully start but every safety alert and electrical alarm will go off in my car and nothing clears it until I drive for about 5 minutes then they all clear. I went to AutoZone and they said my battery was normal health. When this slow start happens I also notice that my vehicle doesn’t accelerate as well and it feels like it’s trying too hard to the point it will jerk forward even when I’m only lightly pressing the accelerator. I noticed this, 2 winters ago (2024) as well and I thought it was due to the very cold weather we had. Brought it to my sister’s fiancée and he couldn’t find any DTC’s but agreed something felt off. The problem stopped and now it’s the middle of summer 2 years later and doing the same thing, to the point where I’m trying to merge onto I-95 and my car isn’t accelerating fast enough and I almost got rear ended!! It only happens at speeds under 50 and is extremely unsafe to have a vehicle where you don’t know if it will just turn off while you’re driving, stop accelerating or decide to not start that morning!!!

The engine mounts on this vehicle failed. Dealership and many others online have stated that this seems to be a reoccurring issue with the 2021-2023 generation of Hyundai elantras. The vibrations of these failed motor mounts become so severe that they can dislodge the brakes making it very unsafe to drive. Hyundai should be doing a recall for this to avoid safety issues for their customers

The vehicle is a 2023 Hyundai Elantra N Line purchased from CarMax in February 2026 with approximately 40,000 miles. It currently has approximately 49,000 miles. The vehicle intermittently cuts off, hesitates to accelerate, and jerks/shudders during acceleration. The specific failed component or system is UNKNOWN because CarMax has not yet provided a definitive diagnosis. The suspected problem involves the engine, fuel/ignition system, transmission, electronic throttle, or another powertrain/control component, but this has not been confirmed. The vehicle’s sudden loss of power and hesitation during acceleration creates a safety risk because the vehicle may fail to accelerate when needed, including when entering traffic, changing lanes, or attempting to avoid a hazard. The unexpected cutting off of the vehicle also creates a risk of being stranded or struck by other vehicles. The problem has been reported to CarMax, but to my knowledge it has NOT been definitively diagnosed or confirmed by a dealer or independent repair facility. CarMax has required a diagnosis before proceeding with further assistance, resulting in delays in addressing the defect. I contacted Hyundai regarding the vehicle and was informed that the vehicle’s original sale/in-service date was October 6, 2023, and that Hyundai has no recorded service history at a Hyundai dealership since that date. Hyundai has not yet physically inspected the vehicle for this complaint. The specific warning lamps or diagnostic messages associated with the failure are UNKNOWN. The primary symptoms are the vehicle cutting off, hesitation when accelerating, and jerking/shuddering during acceleration. These symptoms have continued and remain unresolved. The vehicle is available for inspection upon request. I am requesting that the vehicle be professionally inspected and that the underlying cause of the loss of power, hesitation, and jerking be identified and documented.
