2018 Kia Soul — Known Issues & Recalls

While driving your 2018 Kia Soul, you heard an abnormal knocking sound from under the hood, and the check engine and oil warning lights came on. The dealer diagnosed a blown engine that requires replacement. This issue may be related to a known manufacturer recall (Campaign 20V750000), and it occurred at approximately 95,000 miles.

Your engine seized at 165,000 miles after months of excessive oil consumption—losing half to a full quart every 3,000 miles despite regular oil changes. Multiple technicians identified low-pressure piston rings as the likely cause, confirmed by compression tests showing one cylinder at 0 psi while others read 55-58 psi. You heard engine knock while accelerating and the engine shut down completely. Fixing this will require a complete engine replacement.

Your engine completely shut down while driving on the highway, with the check engine light coming on just before it stopped. This happened only 183 miles after the dealership completed warranty work and inspection, creating a dangerous situation. The repair will likely involve diagnostic testing to identify why the engine stalled and addressing whatever underlying engine issue triggered the check engine light.

Your check engine light came on while driving on the freeway, and you discovered the oil level was completely empty on the dipstick even though you had checked it just a week before. Your engine is now making a knocking sound due to excessive oil consumption. The issue may require an engine inspection to identify the cause of the oil loss, which could involve anything from an oil leak to internal engine wear.

Your engine suddenly stopped accelerating on an exit ramp and seized completely, creating a dangerous driving situation with no warning signs beforehand. The engine failure required replacement with a used engine at a cost of $8,817.91. The issue appears related to known defects in 2018 Kia Soul 2.0 engines involving excessive oil consumption, piston ring problems, and bearing failure that Kia has settled in class action lawsuits.

Your 2018 Kia Soul developed a severe shuddering and near-stalling problem at low RPM with a flashing check engine light, exhaust smoke, and an engine control warning. Before this happened, your engine was knocking intermittently, showing oil pressure warnings, and burning excessive oil. Diagnostic codes P0300 and P0303 were found, and the dealer identified a burnt valve and seized starter but refused to perform the bearing clearance test without payment, even though you believe this may be a known defect covered under warranty. The engine failure caused a safety risk when the vehicle nearly stalled in traffic. The repair will likely involve inspecting the engine bearings and potentially replacing internal engine components or the entire engine.

Your car is using more oil than normal between oil changes. You may need to top off the oil level more frequently than expected. This could indicate internal engine wear or a leak that needs to be inspected. A mechanic should check for oil leaks, worn piston rings, or valve seal problems.

Your engine oil may have low composition quality, causing problems with engine performance. You might experience issues like poor lubrication or engine wear. Kia appears to be aware of this problem. A solution may involve an engine oil flush and refill with the correct specification oil, or potentially an engine inspection if damage has occurred.

Your engine is leaking oil into cylinder #2, which then burns off and damages your exhaust system. When oil builds up in that cylinder, your engine suddenly loses power and performance drops significantly, which can be dangerous in traffic. The fix will likely involve diagnosing why oil is entering that cylinder (possibly a bad piston ring or valve seal) and replacing the damaged components.

Your engine has low compression in cylinders 3 and 4, even though your car only has 40,000 miles on it. This is a significant engine problem that typically requires internal engine work to fix, such as replacing piston rings, valves, or a complete engine overhaul depending on the root cause.

While driving on the freeway, paint flaked off your hood and flew onto your windshield, blocking your view and creating a safety hazard. You had to pull over to clean the paint off the glass. This issue involves premature paint deterioration on the hood that needs to be addressed.

Your car's clear coat has started peeling off the driver and passenger side mirrors since early 2024. White paint is chipping off in a straight line where your red roof meets the white side panels on both sides, likely from a paint tape line during manufacturing. Starting in early 2025, white paint on your hood began flaking off in random spots, exposing the gray body underneath. This will likely require professional repainting of the affected areas to restore the clear coat and paint finish.

Your car suddenly enters limp mode (reduced power mode) and loses power steering without warning. Before this started happening, your battery was boiling and leaking fluid, and you had a bad alternator replaced. The boiling battery poses an explosion risk, and losing steering power while driving is dangerous. The problem persists even after multiple diagnostic checks since January. This issue likely involves the electrical charging system and its ability to properly power your vehicle's steering and engine systems.

Your 2018 Kia Soul was taken to a Kia dealership for a federal airbag safety recall, but after seven months in their custody, the recall was never completed. The dealership demanded payment for diagnostics and refused to authorize the necessary repairs, then asked you to pick up the vehicle without finishing the recall work. When you retrieved it, you found missing or altered components and extensive water damage that weren't present when you dropped it off. Your vehicle still has an unresolved safety recall and may have compromised electrical and safety systems, making it unsafe to drive. Completing the recall will likely require diagnosing and repairing the airbag system and addressing any water damage to electrical components that occurred during dealer custody.

Your 2018 Kia Soul is experiencing sudden, unpredictable loss of power while driving, with the check engine light repeatedly coming on. This makes it difficult or impossible to accelerate or maintain speed in traffic, creating a safety risk when merging or crossing intersections. Despite multiple dealership visits over a year, including a month-long service stay, the problem keeps returning within weeks and remains undiagnosed. Fixing this will likely require comprehensive engine diagnostics, fuel system inspection, and possibly replacement of faulty sensors or engine components.

Your vehicle has an open airbag safety recall that hasn't been completed for over six months. After a Kia dealership's involvement, your car's diagnostic port stopped working properly, which is preventing them from completing the recall. A second dealership says they can't finish the recall and wants thousands of dollars just to diagnose the problem. This may require repairing or replacing the diagnostic port and associated wiring to restore communication with your vehicle's computer systems.

Your steering wheel becomes difficult to turn left or right while driving, and occasionally feels loose and unresponsive with no warning lights appearing. A mechanic diagnosed that your steering column gears and nut need replacement, and a dealer inspection found that your steering gears, steering coupler, and steering rack all need to be replaced. This repair involves replacing multiple steering components to restore normal steering control.

Your car suddenly jerked forward when you pressed the accelerator pedal while driving. The dealer inspected your vehicle but couldn't identify or fix the problem. This type of sudden acceleration issue typically involves checking the accelerator pedal sensor, throttle body, or engine control computer.

Your car is consuming oil much faster than normal. You may need to top off the oil between regular service intervals. This could indicate internal engine wear, a leak, or a problem with how the engine is burning fuel. Your mechanic should inspect the engine for leaks, worn piston rings, or valve seal issues.

Your headlights appear blurry, and upon closer inspection, you've discovered both headlights have tiny cracks running throughout the entire lens. These aren't small chips—they're numerous hairline cracks across the surface. Addressing this will likely require replacing both headlight assemblies.
