Hyundai Elantra GT

2017 Hyundai Elantra GT suffered leakage from the hydraulic brake lines located under the driver's seat which can cause sudden and total braking failure. The leakage was caused by severe rust and corrosion trapped by the underbody panels. The fuel line was also severely corroded, with imminent failure. While Transport Canada issued an official safety recall for this exact engineering defect on the same generation of Elantra GT under Transport Canada (Campaign 2023125), Hyundai Motor America…

The Engine stalled completely at highway speeds. It was then towed to the dealership and was diagnosed with engine rod bearing failure. Hyundai is denying the warranty extension for this engine failure based on an incomplete 'Service Campaign 966' that does not appear on the NHTSA public recall database, leaving consumers unnotified of safety-critical software updates.

I bought a vehicle used and it malfunctions in six days. It is a safety hazard to me the driver and other drivers on the roads. The vehicle is weighing heavy on the passenger side the car is not parallel. Also the vehicle stalls while driving. The pedal stops giving power to the car. I attempted to fix the car and the problems still persist. The mechanics said the car need shocks, struts, and wheel alignment.

My vehicle was brought to an authorized Hyundai dealership In November 2025 to complete safety recall campaign KSDS (Campaign 966). Soon after picking up the vehicle after the dealer flashed the ECU, the vehicle went into a permanent, dangerous limp mode that severely limits the engine's RPMs, making it impossible to accelerate to highway speeds. The vehicle's computer displays zero OBD-II diagnostic trouble codes (no P1326 or standard fault codes). The dealership is refusing to address this…

The vehicle is experiencing excessive engine oil consumption. The engine burns approximately one quart of oil per week during normal driving conditions. There are no visible oil leaks, and no warning lights, check engine light, or other dashboard messages have appeared. The oil level drops rapidly between oil changes and requires frequent topping off to prevent the engine from running low on oil. This condition creates a safety risk because the engine could suffer sudden damage, loss of power,…

I am writing to formally log a critical safety and product reliability complaint regarding my Hyundai Elantra GT. The vehicle has suffered catastrophic engine failure characterized by severe rod knock. This failure occurred without any prior warning from the vehicle’s onboard diagnostic systems, exposing an engineering and sensor flaw that creates an immediate safety hazard.The vehicle was operating normally when it suddenly developed a distinct, heavy metallic knocking sound from the engine…

The vehicle is experiencing engine-related excessive oil consumption, which has led to failure of the catalytic converter and emissions system. The root issue appears to be an internal engine defect causing oil to burn during operation. Yes, the vehicle is available for inspection upon request, including the engine and catalytic converter components. The excessive oil consumption creates a risk of engine damage or sudden engine failure while driving, which could lead to loss of power in…

After a Hyundai dealership installed the Knock Sensor Detection System (KSDS) update to prevent engine bearing failure and potential fires in certain Theta II, Nu, and Gamma engines, my Elantra GT is stuck in limp mode and will no longer accelerate. Since it takes my car a very long time to reach safe driving speeds, I took the car back to the dealership and they conveniently blamed the catalytic converter. I went for a ride with a California BAR associate, and he agreed that the update was…

Engine consumes large amount of oil requiring oil refill every week, without turning on check engine and/or engine oil light. Raising the chances to cause accidents due to engine failure while driving, and requiring mechanical intervention to rebuild the engine or a total engine swap. There are over 40 other complaints about this same issue, and it needs to be addressed.

I've contacted Hyundai to try and do a recall repair on my Hyundai Elantra GT 2018 both through a local dealership (Planet Hyundai in Golden, CO) and Hyundai corporate. The engine is stalling and knocking very bad to the point where it's no longer drivable. It's burning oil non-stop and I am constantly adding oil to it. I'm getting pushback from Hyundai saying I never fixed the recall when I was actually not notified to begin with. I'm the 2nd owner of the car so if I was never notified, how…
