Engine Knocking Noise problems of the 2015 Kia Motor Optima

I was driving home from work and I noticed my vehicle having a hard time picking up speed and soon after it was a noticeable knocking noise coming from the engine. The rpm and dashboard gauges were very sporadic. I parked the car and popped the hood to find that there was somehow absolutely no oil, but no current sign of leaking from underneath. The car continues to knock when I start it up and am afraid of it overheating and it is currently parked. It smells definitely like burntness and when shifting into d3 and d it seems to be the most apparent that the engine could be having touble. Speeds and rpm gauge are most sporadic at high speeds and the exhaust pipe seems to have residue of some sort that isn't normal.

Did an oil change and after that engine light came on and ever since I've been hearing a knocking noise.

I wanted to add more information to my complaint. When in motion in front of high school car went into limp mode with knocking noise coming from engine. My husband is a mechanic and discovered metal flakes inside engine. I was never notified of any recalls involving the engine. Now I have to purchase a new or remanufactured engine costing estimated $3000 to $4500 not including core charges and shipping fees.

As I was driving on the interstate 3 vehicles passed waving frantically before speeding by. I noticed a reflective orange flicker along the base each vehicle. This was followed up by a loud knocking sound before I lost all accelerating power but retained rpm revs as I pressed the pedal. I allowed the momentum to get me as far up the exit ramp as possible prior to pulling over onto the grass. I placed the car in park and turned it off to be met with an instant roll of smoke up the front windshield, out of the front grill, and from the passenger side tire area. I exited the vehicle to the sound of liquid hitting a hot surface and hissing. I stepped away from the vehicle and looked underneath to be met with rolls of fire dripping to the ground from beneath the engine and along the bottom center of the undercarriage of the car. I immediately cleared the area and my vehicle was complete engulfed in flames in less than 4 minutes. No sensors or alarms notified me of any type of malfunction.

Had oil changed and a month later noticed the car making a knocking noise and skipping while driving on city street and highway. Had the oil rechecked and the car was out of oil. First thought that the oil place forgot to put oil in. However, it was later determined by a mechanic that the valve was gone in the engine and I would need a new engine at 130,000 miles in a 2015 kia Optima lx. The car stopped on the highway at 70 but I was able to move to the side.

Vehicle started to make a knocking noise going down the hey at 60 mph. Car was taken to the dealer and catastrophic engine failure was diognosed. Kia commissionsers was notified.

Driving down the freeway- car died- all dashboard lights came on- started back up-- had a knocking noise- drove it out of traffic and parked it. Towed to kia dealership- engine is gone. Maintenance has been done regularly- the check oil light never came on - still isnt on- no oil in the engine- check engine light came on only after the car died. . This is very dangerous- the cars die in the middle of traffic.

The engine began making a knocking noise, then stalled. Upon inspection at auto shop it was discovered that the engine seized and was a complete fail. The vehicle was traveling on a highway at around 65 miles per hour. The car has had all preventative maintenance performed and I can provide documentation as to that.

My vehicle starting driving sluggish and making an increasingly knocking noise from under the hood. I took the car for a routine oil change and 2 weeks later checked in a normal ride to work I realized my vehicle was smoking really bad from the exhaust and a horrible smell of burnt oil filled the interior. I took the car home and parked it. Less then a week later I get a recall letter for the engine. I had the car towed in to kia they ran a test my engine has blown they put me in a rental for 16 days this began 6/20/17. I came to get my car on 7/8/17 and didn't even get down the street before getting pulled over and notified that my car is roaring smoke the exhaust again. I immediately brought it back. They drove it with me and also agreed it was still smoking and had nothing to do with old oil burning off and now my a. C. Is acting weird. They placed me back in a rental and told me they would open a ticket. To be very honest I'm trying to keep present but I'm very very scared and concerned about getting back in the car. I feel trapped and I'm still making payments on something I can't even drive and feel unsafe in.

Engine failed on my 2015 kia Optima while exiting the freeway. The car was making a knocking noise, started smoking, started to lose power, and stalled. I had the car towed into a kia dealership. Kia issued recalls for this problem on several models through the 2014 models. They failed to issue a recall for 2015 models. They initially refused to honor the warranty and wanted close to $6,000 to replace the engine. Financially, this was not possible for me and I had to have the car voluntarily repossessed. I filed a formal, written complaint and explained the situation, including the fact that I had to have the car repossessed. At that point, they responded with a settlement agreement stating they would honor the warranty, if I released them from further responsibilty. This offer was not feasible, as I no longer had the vehicle. At this point, they told me there was nothing else they could do for me. I asked for a written response to my complaint and was told they cannot do that.
