<prompt> Human: Hey reddit, yesterday i brought in my 2014 Challenger for an oil change at my local firestone. Everything goes well, i pick up my car and start it and it works. Then when i start driving off, my engine basically stalls up at around 2000 rpms and it can barely drive, not to mention an insane rattling sound coming from my engine.I drive back to firestone, they inspect it again, then the mechanic comes back and says it was an oil filter cap. I know that thats definitely not the problem but he insists and he puts a new one. He fixes it, i start my car, it works, then i drive a block or two down and the same problem as before. My car is under warranty so i call my local dodge dealership so they can check it out and they say theyre booked for the next week so i decide to once again bring it back to Firestone. I drove it back to Firestone, i talk to the manager, and i leave it overnight so they can inspect it more, he also reassures that Firestone will reimburse me for the ubers i had to take, etc. Well i wake up today, call to see whats up and he tells me that its definitely an internal issue so now i have to wait for both a master mechanic to come check it out and for Firestone claims to call me today.Im just a college kid who needed an oil change on a car my parents bought me, and now my car is stuck there and i just dont know what to do. What do i do in this situation? edit:typos Update!- Turns out Firestone never did the oil change, they basically drained my oil and gave me back my keys. So now theyre covering a new engine 8000 of damages. Thanks Firestone! You da best sAssistant: By fixing an oil filter cap do you mean putting an oil plug into the oil pan? As in they did not put an oil plug into the pan when they were done? Which would also mean that they didnt put oil into the car as well.Human: idk, he told me oil filter cap  <response>: Well if you had no oil pan plug or oil filter in the engine you would not have any oil. If you didnt have an oil fill cap you would just have a small mess under the hood, but nothing that would cause damage in the time frame and distance you were talking about. Forgetting to put oil in a car happens much more often at these places than you think. They will pay for their mistakes, begrudgingly most of the time, but just dont relent. A lot of the time these people try to wear people down to get people to give up. Just keep your cool with them knowing that you are in the right and it should work out.
