I purchased my 2015 Hyundai Sonata recently with only 46K miles on it. After 3 weeks, the engine started clicking loudly and it literally sounded like a roller coaster being pulled uphill when under load. A week later the ticking was constant. My husband changed my oil and strained it, finding small metal fragments in the oil. These fragments are from an engine defect that Hyundai even admits having. Now as the second owner, I have no service records prior to ownership and my warranty claim was denied because of it. How can this be happening" Hyundai admits defect but are still allowed to rip off consumers with bad engines" the gdi Hyundai engines are defective and it cost me $3,000!

Hi NHTSA, I drive a 2015 Hyundai Sonata and followed all the recommended maintenance. I started to notice my oil level was below low after 2000 miles at 47000 on the vehicle. I thought it was not filled correctly and had my mechanic check it. Also, I told my Hyundai dealership in laurel, md about the finding. I decided to top off my oil and closely monitor the status. On my next oil change, after 2000 miles my oil was low again. I add roughly 1.5 qts to top it off. I brought my car until Hyundai for an oil consumption test. The mechanic did not note how much oil he started as the baseline; however, the dip stick was over the full mark. After 3000 miles, my oil was at the low level. Per Hyundai owner manual, I can drive 7500 miles between oil changes with non - extreme driving. Hyundai stated my car was not consuming oil, and this is normal.

On or about 3/15/2015, purchased a new 2015 Hyundai Sonata. Maintained oil changes in accordance with "normal maintenance schedule" as described in owner's manual. In 5/2019, while driving on a highway, vehicle began sputtering, knocking and engine light came on. Was told engine "threw a rod" and punched a hole in the engine and now engine needs to be replaced.

The check engine light is illuminated and when coming to a stop, the vehicle lunges/surges forward as if the brakes are failing and I'm going to hit the vehicle in front of me. I took the the vehicle to 2 local jim click Hyundai dealers, the fault code is P200A and they stated the issue is most likely replacing the intake manifold which would not be covered by the powertrain warranty and my mileage is 85,000 presently. I would think that it would be a warranty item because the intake manifold is bolted to the engine and connected to the engine with wires. Now I'm stuck with a $1000 repair bill.

When excelerationhe care makes a noise, sounds like shavings of metal in engine some days are worse then others. I've taken it to two different Hyundai dealers and one heard it and said they have no idea what it is and have others with same problem and the other dealer said they didn't hear anything. My husband has bad hearing but one day he drove it to work and said he finally heard it as well. I do notice that the pick up is hesitant making it hard to stay in flow with the traffic at times. My gas per milage performance has decreased some what as well which

While attempting to merge onto interstate 85 in atlanta, the car hesitated and would not accelerate. At the same time, an alarm began to chime and once I avoided a collision, I noticed a flashing engine symbol on the dash. At this critical time I was "lucky" to have not been involved in a fatal car accident. The car limped to the autozone and P01326 was discovered. The AZ employee and the longtime manager said they were surprised when the code did not pull up any info in the database. I researched the internet and found some information and the 2 minute Hyundai video on the bearings, catastrophic engine failure, potential fire and the knock sensor. Southtowne Hyundai said it was a wiring problem and reset the code. I asked if the vehicle was safe to drive and the representative said yes but within 5 miles of leaving the dealership, the check engine light came back on. I have sent several emails to the SE regional manager, steve flood, and southtowne's GM, charlie simmons, but they have not replied. Their underlings have. I have lost faith in the vehicle and believe it (and other Hyundai cars) is unsafe.

Engine hesitates to put out power when taking off from a stand still. Transmission upshifts instead of downshifting when pressing pedal pedal 50% of the way. These problems occur in city driving.

- Coachella, CA, USA

Applying the brakes at a stop requires the brake pedal to be firmly held to the floor otherwise the engine will start reviving up and move out fast if the brake is released. Also appears that the transmission when moving the shifter to park does not mean the car is in park. I did this once in a store parking lot. The shift handle was in park. But as soon as I took my foot off the brake and opened the door car took off. Caused $ 6,700 to fix all the damage. Engine does not come off fast idle. When I first got the car. Idle RPM was between 500 and 750. Now the idle never goes below 1200-1300 RPM. I tried various brands and grades of gas including ethanol free unleaded but nothing helped.

I was in motion (just coming out of a steep canyon on an interstate/highway) and suddenly the engine just stopped. The check oil, check engine, and check battery lights flashed because my ignition was still on, but I had to try to coast to a safe stop. No warning, no overheating, no issues with battery or oil or other fluids. The engine just squeaks faintly when I turn the key and won't turn over.
