Selected complaints filed with NHTSA by 2012 Kia Soul owners, lightly cleaned up (personal details are redacted by NHTSA).
My 2012 Kia soul base, had this SC176 recall which I took it into the dealer, at that time I really didn't know exactly what the recall consisted of, until months later after researching the performance of my car, my engine lights comes on and stays on for two weeks ,then go off a day and it's back on, my car drives sluggish and it's acceleration power is bad , where it won't get up to necessary speed, and it making a loud noises when I accelerate ,which the mechanic said it's my Cadillac converter which was under recall and most likely damaged , from high exhaust gas temperatures,I do believe it's all under the last recall, my engine was damaged and should of been replaced along with the catalytic converter, I believe the KIA dealership knew of the damages but didn't replace my catalytic converter or my engine, my cars performance has gone down tremendously , month by month because of …
On 12/ 22/ 2025 I went to start the 2012 KIA Soul and it would act like it would start but, it would not turn over. Battery was fine checked it. Let it set a moment and tried it again would not start. Called a wrecker and towed it in. The service guy tried and couldn't get it to start either. He ran a diagnostic on it, there were not type of codes, no check engine light nothing. He had it for until 1/5/2026 and when they went to check it it started right up. They drove it for 20 miles to check to see if it would cut off while driving, it didn't. It starts now but for how long. Here's the strange thing, I drove it 20 minutes away and I noticed that the counter for when You fill up with gas states how many miles you have left to go before fill up was counting UP not DOWN. So I think it could be the computer or electrical, I thought it was the fuel pump at first. …
Took car in for recall SC176 and was told by Taylor Kia in Lima, Oh that what was happ wasn't throwing a code. Said they fixed the knock sensor and that if it is that problem it would go off and they could check it again. My car ran worse than before getting it back. What is happening to my engine is exactly what is detailed in the recall. I drove home 35 minutes shacking and knocking the whole time and no engine light? You can hear the rod knocking in my engine. Exactly how it is explained in the recall. So, now I'm stuck with an engine that going to be ruined when the rod does flys out. Hopefully not harming me or anyone else. This is ludicrous and poor work done.
I was driving and my check engine code went on , I got it checked by autozone and it was for the catalytic converter. My car has since ran horribly, there feels like a lag in acceleration and it makes a hissing/air noise that comes from the catalytic converter it gets overheated and causes my car to go in limp mode and when I asked a mechanic friend they said it's very clogged which has caused me to park my car and not drive it because I was recommended to not drive it being in this condition then I was send a recall in email. It has one owner and we have kept up with maintenance very well.
My car stalls and the engine light frequently stays on, my car is driving sluggish every since I got the recall adjustment my car has declined in performance and the engine light started coming on more frequently up until now, it's loud at and experiencing a great lost of power ,the computer is giving the code PO420 reading as bank 1 oxygen sensor , I had intended changing out both sensors, but wasn't sure if it's a damaged engine effecting the Cadillac converter from the 2019 recall, # 19V120000 giving a false reading.
I got the recall SC284AM - HECU FUSE REPLACEMENT Done. As soon as I started the engine at the Kia dealer thick smoke started coming out of the exhaust pipe. When I showed it to the dealer they said it has nothing to do with the fuse replacement. The car was perfectly fine before the fuse was replaced. To check out the reason for this the dealer is asking $300. It's definitely the result of the fuse replacement. Need help.
The fuel tank is made in two parts a top and a bottom and assembled together along with mounting brackets. The joining seam leaks fuel when the fuel level is greater than half fuel. The fuel leakage is very close to the exhaust system creating a potentially dangerous Fire and Safety hazard. The design is flawed because the mounting brackets continually stress the joint which separates to cause fuel leakage.
I've had recalls on antiknock sensor and catalytic problems with vehicle I've had them repaired at kia dealerships to no avail I've had catalytic converter replaced with my own money because the solutions did not fix problems..still having severe issues.vehicles engine light blinks three times and goes into limp mode which prevents engine from accelerating past 45 mph
So I purchased a 2012 Kia Soul A few months ago and since I got it the car has been having issues with accelerating the car delays to respond and I have had many closed calls specifically when entering a freeway the car losses power and I have to really press on the pedal for the vehicle to respond then the check engine light started to come on showing Code P0420 Catalyst operating below minimum threshold. I looked up online and all Kia souls starting from 2012 have a recall regarding the Catalyst converter and because of the issue my vehicle is having a weird rattling or knocking sound on the engine I looked up online and this is what I found Kia Motors America (Kia) is voluntarily recalling 2012-2016 Kia Soul vehicles with 1.6L Gasoline Direct Injection (GDI) engines due to high exhaust gas temperatures that may damage the catalytic converter. …
My Kia Soul 2012 has a noise at cold start that last 15 to 20 second, it feel like some thing loose. Dealer at sahara, las vegas nevada had it for three times and 4 days each time and the first time they said was the timing tensioner and they replaced, but noise still there so they have two times more and at the end the said the noise is the oil pump, os if it was the oil pump why they replace the timing tensioner ? The noise still every day in the morning, plus smelling gas by the motor and infest the whole garage, so I took it to dealer at henderson ,nevada cause I found oil leaking by ocv ( oil control valve, so they replace two ocv and still leak oil, so I realized looking deeply that first two injectors are leaking gas, mixing with oil. They asked if oil got on the garage floor and when I said : no yet, so they said can not do any thing. …
