2023 Hyundai Elantra Reliability Score & Common Problems

Owners of the 2023 Hyundai Elantra frequently report issues with the engine losing power or stalling, often without warning. Common symptoms include the vehicle losing motive power while driving, sputtering, and stalling at slow speeds or during gear shifts, which can occur at various speeds including highway conditions. Several complaints involve the engine shutting off unexpectedly, with some owners noting a message to shift to neutral and restart. These issues typically arise within the first year of ownership, with some reports mentioning as few as 290 miles on the odometer. Safety implications are significant, as these failures can occur in traffic or on highways, increasing the risk of accidents. Additionally, there are reports of oil leaks and coolant system failures, although these are less frequently mentioned.

Owners report several issues with the 2023 Hyundai Elantra's vehicle speed control, particularly related to cruise control and braking systems. Multiple complaints describe the cruise control unexpectedly accelerating to 110 mph and being difficult to deactivate, with some owners noting this occurs after setting cruise control at lower speeds and persists until the vehicle is restarted. This issue is reported at low mileages, such as 50 miles. Additionally, owners frequently mention unintended deceleration or phantom braking, sometimes linked to Forward Collision Avoidance systems, which can cause abrupt speed changes and skidding. These issues present potential safety risks due to sudden speed changes and loss of control, with some problems remaining unresolved despite dealer visits.

Owners of the 2023 Hyundai Elantra frequently report issues with the steering system, particularly related to the lane assist feature and steering control under various conditions. Complaints describe the vehicle independently steering to the right when lane assist is active, sometimes resulting in crashes, and steering wheel lock-up during adverse weather, leading to loss of control. Additionally, some owners experience abrupt vehicle shutdowns, losing control over both steering and brakes. These issues are typically reported at mileage ranges from approximately 7,000 to 20,305 miles. Safety implications are significant, with multiple reports of crashes and near-misses due to these steering-related failures, making it crucial for potential buyers to be aware of these patterns.

Owners report frequent false activations of the automatic emergency braking system in the 2023 Hyundai Elantra, with incidents occurring at various speeds, including highway speeds up to 70 mph. Complaints commonly describe the vehicle unexpectedly applying brakes when no other cars are in close proximity, sometimes leading to sudden stops that could potentially cause rear-end collisions. These issues have been reported as early as 3,500 miles and continue beyond 11,000 miles. One complaint involves a crash where the forward collision warning system failed to detect a vehicle, resulting in significant vehicle damage. Another distinct issue involves a subframe pressing against a hard brake line, which Hyundai reportedly denies as a factory defect. These patterns suggest potential safety risks, particularly with unexpected braking at high speeds.

Owners report multiple issues with the air bags in the 2023 Hyundai Elantra, particularly non-deployment during collisions. Several complaints involve crashes where air bags, including front and side, failed to deploy, resulting in injuries such as concussions and whiplash, with vehicles often declared total losses. Another issue involves delayed air bag deployment, as one owner describes air bags deploying 10-15 seconds after a minor collision. These problems are noted at varying mileages, from 31,000 to 71,000 miles, and have significant safety implications, given the injuries and total vehicle losses reported. Buyers should be aware of these patterns, especially if considering a used model with similar mileage.

Owners report several issues with the 2023 Hyundai Elantra's lane departure and related safety systems. Complaints frequently mention the Lane Keeping Assist (LKA) system taking control and steering vehicles out of their lanes without warning, including into oncoming traffic or towards barriers, which poses significant safety risks. Additionally, some owners describe the automatic emergency braking activating unexpectedly when other vehicles pass closely, even when not signaling a lane change. There are also reports of multiple safety features failing simultaneously, including lane departure warnings and blind spot monitoring, which can affect vehicle control. These issues are noted across varying mileage ranges, and one report involves a crash with an injury. Potential buyers should be aware of these reported incidents and the associated safety implications.

Owners of the 2023 Hyundai Elantra report issues related to excessive heat and oil consumption. One owner describes the center console becoming extremely hot while driving, attributed to heat from the exhaust affecting the interior, with the issue occurring at approximately 8,000 miles. Another owner of the Elantra N variant notes a significant oil leak, with the engine consuming one quart of oil every 100 miles, leading to a recommendation for engine replacement at around 1,520 miles. While no safety incidents such as crashes or fires are mentioned, these issues could affect vehicle comfort and reliability. Potential buyers may want to inquire about these specific problems and any dealer interventions when considering this model.
