2023 Hyundai Elantra

For the 2023 Elantra, the most commonly reported issue centers on the forward collision avoidance system behaving unexpectedly. Owners frequently describe the automatic emergency braking activating on its own, most often on highways when faster-moving vehicles pass nearby, causing sudden, unintended hard stops. Some owners also report the system triggering in low-speed situations like parking lots. Electrical system complaints are the second most common category, with owners describing warning lights illuminating while driving, radar and blind spot monitor malfunctions, and in some cases a loss of normal vehicle performance following those warnings. A smaller but notable group of engine-related complaints involves the hybrid system flagging faults mid-drive, sometimes leaving the car unable to accelerate normally. The false-braking pattern from the collision avoidance system is the most consistent thread across the complaint set, with owners describing it happening more than once on the same vehicle.
