4/5 Overall
NHTSA 5-Star Safety Rating
Engine complaints dominate the 2017 Elantra's complaint picture, with owners across a wide mileage range describing stalling while driving, excessive oil consumption, and internal mechanical noise, particularly rattling that often accompanies a P0014 camshaft position code. The oil burning issue frequently persists even after timing chain replacement, suggesting the problem isn't resolved by that repair alone. Stalling tends to get reported during deceleration and low-speed maneuvering. Structure is the second most-reported category, with a notable volume of complaints, though the specific structural symptoms vary. Steering complaints also appear in meaningful numbers, with owners describing handling concerns, though engine issues clearly generate the most consistent and repeated patterns in this model year.

By System
The 2017 Hyundai Elantra has 6 recalls, the most serious being a brake booster defect where an internal diaphragm can unseat, causing a vacuum leak that reduces or eliminates power brake assist and forces the driver to push the pedal much harder to slow the car, significantly extending stopping distances.
A separate brake booster recall covers a related failure mode where the booster can stop working entirely, again removing power assist and lengthening the distance needed to bring the car to a stop. Prior repair attempts did not fully resolve the issue across all affected vehicles, which is why both campaigns exist. In practice, both defects leave the driver with a brake pedal that feels unusually stiff and a vehicle that takes longer than expected to stop.
Two recalls involve the electric power steering system. A connector at the power steering motor can be damaged, causing the system to lose its assist. At low speeds in particular, steering can suddenly become noticeably heavier, requiring much more physical effort to turn the wheel and raising the risk of losing control in a tight maneuver or unexpected situation.
The remaining two recalls cover the front airbags. In one group of vehicles, the driver-side airbag inflator module may not deploy the bag fully in a crash, reducing the protection it provides. In another group with a narrower manufacturing window, a front airbag may fail to deploy at all, leaving the driver without that layer of crash protection entirely.
