My car is burning through a quart of oil appx every 600 miles- this is NOT normal it's excessive oil consumption.

- St. Petersburg, FL, USA

while driving about 6/7 lights on the dash comes on and the car stops. This happened several times and I took it to my auto mechanic Christian Brothers at Dacula, Ga. They said it is a soft ware problem and Hyundai USA does not accepts their are any software malfunction problems. Sometimes the car would start back again and other times it will not. Therefore I had to tow my car twice to the garage to have them check it out and fix it. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

- Matteson, IL, USA

The vehicle is driven roughly 80 miles a month for groceries and doctor appointments only. It has 40,900 Mike's on it and began to continually have the check engine, ABS, and traction control lights come on. The vehicle once put in drive or reverse will increase speed on it's own, nothing faster than about 7-10 miles per hour on a flat surface. I also noticed when these lights are on and I am in park the odometer will jump from 0-80,90, mph randomly. The lights will not always stay on or come on, just occasionally. I did take it for inspection for the above problems and had to replace the intake and outtake valve on cam shaft and a sensor (may have named them wrong). Just want to o report in case others are having same issue.

I brought car in to see about engine light they told me it was a cvvt and it would cost $1700 which I couldn't afford they stated that because I did not get my oil changed there they could not cover it even though I had prrof of my oil changes from other companies. So took car to mechanic he stated that if I did have cvvt replaced in 6 months time I would have needed a new engine anyway. So he replaced the engine.

- Brick, NJ, USA

I experienced extremely high revving at idle(about 1500 rpm to 1750 rpm). I also experienced a dangerous loss of acceleration when trying to accelerate. I would put the accelerator to the floor and it would take about 10-15 seconds to reach a safe speed on a highway on ramp. Additionally I am consuming about 1/2 quart of oil per week. I change my oil faithfully every 3-4k miles and have documentation to prove it. My oil was down 2 1/2 qts at one point which I discovered by accident via my mechanic. There was no indication of this with the low oil indicator light. I only discovered this when my check engine light came on and my mechanic investigated the code.

- Cleveland, OH, USA

Engine stalled and there was a loud knocking sound. Had vehicle towed to dealer only to be told that this is a known issue with Hyundai and we need a new engine. No loaner cars available and 36 people are in front of me with the same problem. No timeframe available for a resolution. Huge inconvenience. Called Hyundai only to be told that a case manager would call me in 7-10 days. If it-??s a known issue, why haven-??t they recalled the affected cars like last time?
