Engine control system is STILL faulty. The engine light will not go off, even after the so called recall Software fix and the brand new engine put in my car in 2025 among other MULTIPLE brand new parts and repairs to my car trying to resolve the engine issue, oil consumption and fuel/gas consumption at rapid and alarming rate, every time after I fill my gas tank.
I am writing to report safety concerns regarding my 2018 Kia Soul Plus. I have been experiencing several engine issues, including knocking noises, hesitation during acceleration, excessive oil consumption, and an active check engine light. Recently, while driving with my daughter, the vehicle began shaking and the check engine light flashed three times. Although I strictly adhere to the recommended maintenance schedule, these issues persist. My mechanic identified code P0455, but a smoke test did not reveal a leak. Additionally, despite having a full tune-up in August [2025] at 105,636 miles, I am being told I require another tune-up due to engine misfires. I am concerned about the frequency of these repairs and the overall safety of the vehicle’s engine.
Going through oil so fast excessive oil use
Car stalled in the middle of the road while driving. Took it in to dealer ship for a recall to get this repaired or flashed. Engine burning excessive oil. Car has always been kept up with maintenance. While operating the vehicle the car stalled due to low oil compression. Vehicle has aprox 155k miles. Check engine light has came on. Due to the issue that car engine is burning oil there is a new permanent code p0420 which is a bad catalyc converter since the cars emission system is failing. Car has been sitting at home for about 1 month or longer as we don’t drive it and are still financing the vehicle
2018 Kia Soul with excessive oil consumption. 1.6 Liter GDI engine. Base model. Oil is being overly consumed in between oil changes, needing double the quarts in between Kia's manufacturing guidelines.
Engine failure at 121733 due to faulty engine management system. Was able to limp the car to the dealership. Engine had to be replaced due to broken rings in two of the pistons. Car was serviced regularly prior to the insidence.
My 2018 Kia Soul is guzzling oil even after an oil consumption test and a head gasket and valve cover gasket replacement. We are using a quart of synthetic blend oil every 500 miles. We cannot be the only people with this complaint!! Vehicle has less than 95,000 miles on it. The Kia Dealership in Clarksville, TN has been the only place to work on our vehicle since buying it a little over one year ago. Said vehicle has been guzzling oil since day one of our purchase.
Oil consumption issues Not normal Don’t understand why Kia knows about this issue but won’t fix it Over a year with this issue Place in poteau Cavanal Tire said it should be addressed By Kia not when my motor locks up! Kia says let pour gunk in your car to patch the issue they know about That should be addressed on why they have not fixed it.
I GOT TOLD BY A KIA MECANIC WELL AT LEAST SEEN IT ON MY DASH CAM THAT I AM SOL THAT MY TICKING PROBLEM IS AN ENGINE DEFECT ON KIA'S PART THAT IS CAUSING ENGINE ISSUES AS WELL AS SOMEHOW MAKING MY ENGINEREV EXTREMELY HIGH WHILE STARTING UP AND SOMETIMES THROUGHOUT THE DAY TO THE POINT IF I DON'T HAVE MY BRAKES ON I WILL GO THROUGH A WALL . THAT'S A MENTION SOMETHING IS WRONG WITH THE AIR CONDITION UNIT/HEATER THAT THE HEATER WILL BLOW EXTREMELY HOT SO HOT THAT THE VENTS BECOME PLIABLE AND THE AIR CONDITIONER AND WON'T COME ON UNLESS I START MESSING WITH BUTTONS OFF AND ON OFTEN ON HIGH AND LOW HIGH AND LOW.I HAVE BEEN IN TO KIA MOTORS FIVE TIMES FOR THE ISSUE
WHEN YOU TURN OFF THE CAR THE KEY WON'T COME OUT IF IT'S RAINING YOU GET WET AND SOMETIMES THE CAR WON'T START AND THE REMOTE DON'T WORK. YOU SMELL GAS WHILE YOU DRIVING.
FROM A STOP, THE VEHICLE HAS A SIGNIFICANT HESITATION PULLING AWAY FROM A STOP SIGN/REDLIGHT ETC. AS YOU PUSHING THE GAS PEDAL DOWN, IT HESITATES THEN ACCELERATES HARD. HAS 340 MILES ON IT AT THIS TIME. DEALER AND KIA STATE THIS IS NORMAL FOR THE NEW TRANSMISSION/TURBO DESIGN. EVEN THE SERVICE MANAGER WAS SHOCKED WHEN HE DROVE IT SAYING HE WOULD NOT HAVE BOUGHT IT. I WOULD THINK THIS PROBLEM COULD BE RESOLVED WITH A PROGRAMMING UPDATE. MY CONCERN FOR SAFETY IS TO PART: 1ST, ANTICIPATING THE VEHICLE MAY GO WHEN IN FACT IT HESITATED TO PULL OFF CREATES AN ANTICIPATION EVENT. 2ND, THE HARD ACCELERATION WHEN IT ENGAGES COULD RESULT IN REAR-ENDING SOMEONE. THE ATTACHED DOCUMENTS REPRESENT THE WORK ORDER AND DESCRIPTION OF THE NEW TRANSMISSION. THIS IS A BULLETIN EXPLAINING THE DRIVABILITY CONCERNS, HOWEVER, IT DOES NOT REFLECT THE HESITATION ISSUE.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
