My car just dies on the highway, it let out a loud bang and a puff of smoke after it failed to go above 60mph Mechanic's Assistant: How many miles are on the car? Have you been losing oil or coolant? No neither, there is about 130,000 miles on it i think Mechanic's Assistant: What is the make/model/year of your car? 2011 Kia optimia Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far? Nothing yet it just happened! But sorry 8 meant there was 111,000 miles

Hello and thank you for using Just Answer my name is \*\*\*\*\* \*\*\*\*\* I will be glad to help. Sorry to hear about your car trouble, I'm assuming it won't start back up. Does it sound normal when cranking the engine?

I didn't try to start it again cuz of the smoke
Automotive Expert
It most likely won't start but can you try it?

It wouldn't start!
Automotive Expert
Does it crank faster or slower than normal? Are there any fluids leaking under the engine?

Slower and no leaking fluids, my husband didn't get the oil changed very an extremely long time and just had it changed finally a few days ago. They said it was like sludge, idk if that helps to know lol
Automotive Expert
Unfortunately it sounds like catastrophic engine failure. Do you know where the engine oil dipstick is so you can check the oil level?

Damn. I was afraid on that. Yes I do, it is a dark color
Automotive Expert
I would expect it to look dirty if it was coming out as sludge when you changed the oil. Did you ever have an oil pressure warning come on the dashboard? I wonder if the sludge clogged your oil pick up tube going to the oil pump. Did the place that changed your oil recommend a flush or at least an additional oil change since it was so bad?

They reccomended an oil flush and an additional change

I'm not sure how mechanically inclined you or your husband are but this is going to require some tear down to determine what exactly failed and what the repair options are. I know that engine has had issues and I think they warranty it to 100,000 miles. Sometimes the dealership will extend goodwill on repairs outside of warranty if you have be using them for service.

I think I'll have it towed to the dealership but I have little faith they will do anything. Thanks a lot for your help!

You're welcome, I hope they take care of you!

Filled in regular instead of premium fuel, CEL came on, P0022 code
