“Sudden engine misfire and stall in major metropolitan area in high traffic. Diagnosis from my mechanic was failed valve and complete loss of compression to 2nd cylinder. Symptomatic of repeat catalytic converter issues leading to engine damage. Catalytic converter has been replaced twice-- once out of pocked and once under extended warranting for SC176/NHTSA 19V-120000 at a kia dealership. Engine light turned on just minutes before failure. I am now beyond the extended 150,000 warranty-- engine failed at 167,000.”

“RECALL SC176 INCOMPLETE- WHILE DRIVING IN AN UNINCORPERATED AREA IN [XXX] ([XXX] IN [XXX] COUNTY) THE VEHICLE SUDDENLY LOST ENGINE POWER AND DUE TO THE SUDDEN LOSS OF ENGINE POWER THE VEHICLE WAS DIFFICULT TO STOP ON A DANGEROUS CURVE.

EVEN WITH THE FLASHERS ON OTHER MOTORISTS INCLUDING A SEMI TRACTOR TRAILER NEARLY CRASHED INTO THE DISABLED VEHICLE MULTIPLE TIMES. WHILE ESCAPING THE DANGEROUS SITUATION ON FOOT I NOTICED THE MUFFLER WAS EMMITING SMOKE AND A STRONG ODOR. I WAS ABLE TO RETAIN THE SERVICES OF A LOCAL TOWING COMPANY TO PROVIDE IMMEDIATE EMERGENCY RESPONSE WHERE THEY HAD TO USE MULTIPLE UNITS WITH CONES AND AMBER LIGHTS AND FLAGMEN WITH STROBES TO SET UP A SAFTEY ZONE TO PROTECT ONCOMMING MOTORISTS WHILE THEY CLEARED THE IMMEDIATE SAFTEY HAZARD. THAT WEEK I HAD A LOCAL MECHANIC SHOP CHECK ON THE NO START CONDITION. THEY REMOVED, CHARGED, AND BENCH TESTED THE BATTERY FINDING IT TO PERFORM AT AN ACCEPTABLE AMPERAGE. UPON INSPECTING THE NO…”

“My husband purchased our 2015 Kia Soul 1.6L GDI in 04/18. It was recalled under the NHTSA 19V120 & Kia SC176 in 04/19. The recommended fix? Update ECU Logic. Completed: 04/24/19. Check engine light came in 07/19. My appointment in 08/19, at #1 Cochran Kia showed a P0455 large leak code. Per invoice, manual leak test found no leak, but found gas cap not installed correctly after adding fuel, codes were cleared, & road test performed; "mileage in": 65582, "mileage out": 65583. Was that a road test? In 01/20, the Soul at the dealer for check engine light; P050A code was found & there was no resolution. They sent me home with the check engine light on. Auto Zone recommended catalytic cleaners. I used these because the illuminated check engine light created stress & still does.

More cleaners. 01/22 Auto Zone found replace ignition coils & spark plugs. 04/22 extended warranty expire At dealer on 01/23, for a check engine light.

Steering

44 reports8 crashes1 fire1 related recall
“As I was driving home on the highway, my car began making a noise I never heard before. I looked out of my rear view and began to see smoke coming from my car. As I was trying to get off the highway, my car began to lose control. I couldn’t get completely off the highway so I pulled into a small corner. I realized my hood was on fire when I stopped. I grabbed my purse and keys and ran down the highway as fast as I could. By this time my car was engulfed in flames. A woman saw me in distress and helped me and allowed me to get in her car for safety as she called 911. That’s when the car blew up and we drove off the highway to safety.”
