Noticed a knocking sound in the car. Thought something was loose. No warning lights to indicate an issue. The car stalled while driving down local streets as the car was decelerating. As long as the gas pedal was pumped the car continued to stay engaged. Car taken to mechanic by tow. The car was down 3. 5 quarts of oil. Was overdue by approximately 1000 miles based on the recommendation of Hyundai manual.
Engine starting making a knocking noise. Brought into dealer and was told it had complete engine failure due to broken bearing and I would need a new engine. Denied request through warranty. Only around 43000 miles are on the car. Hyundai informed me it was denied due to oil not being changed properly as evidenced by two areas of sludge on the inside of the hood of the engine. Service records brought to Hyundai showing oil was changed within the 7500 mile as indicated on Hyundai's website and owners manuel.
I had my car for 12 months I bought bran new. It has staled and turn off on me at least 5 times. This is a safety issue especially on the freeway the car loses power and stops. Than before it stops makes a knocking noise.
