Problem overview

Some Hyundai Elantra owners report experiencing serious safety issues due to subframe problems, particularly related to rust and corrosion, which can lead to structural weaknesses and cause components like the control arm to detach while driving. Ignoring these subframe issues may compromise the vehicle's structural integrity, resulting in poor handling, increased wear, and noise or vibrations, posing safety risks for both the driver and passengers. Additionally, some owners find that if the subframe is rusted or damaged, it may require replacement with a new subframe designed for better corrosion resistance, and any rusted rear control arms should also be replaced to ensure safety and performance. Furthermore, some Hyundai Elantra owners report transmission issues, especially concerning faulty speed sensors, which can affect automatic transmission shifting and lead to further complications if not addressed promptly. It is crucial for owners to have their vehicles inspected by a qualified mechanic to address these issues immediately and avoid potential risks on the road.
