Kia Sorento won't start problems

Filed Sep 8, 2026 · Electrical, Transmission · NJ

I am filing a safety complaint regarding a severe, sudden electronic and mechanical failure of the shift interlock system and the Body Control Module (BCM) that compromises vehicle control and leaves the vehicle stranded in active traffic conditions. While attempting to operate the vehicle, the shifter lever suddenly became physically jammed and highly resistant, refusing to shift out of the "Park" position or smoothly engage into "Drive." Simultaneously, the gear selector indicator (P-R-N-D) on the digital dashboard display went completely blank, indicating a total loss of network communication between the transmission range system and the vehicle's central computer network. Because the vehicle's electronic safety "handshake" failed, the vehicle suffered a no-start condition. To operate the vehicle or move it out of harm's way, I am forced to use the mechanical manual shift-lock override tool. Diagnostic scanning at a professional repair facility confirmed a hard Code P0955 (Auto Shift Manual Mode Circuit Malfunction) due to an internal electronic failure inside the Body Control Module (BCM), which handles the safety grounding circuit for the shift interlock solenoid. Safety Risk Statement: This component failure introduces a severe safety hazard. If a driver is required to quickly shift gears or move the vehicle out of an active roadway, intersection, or railway crossing during an emergency, the physical locking of the shifter and sudden communication dropout prevents immediate vehicle control. Bypassing a safety system via a physical override tool while stranded in traffic is a dangerous distraction. There is an existing safety recall for this model year regarding shifter rollaways (Recall SC246), but it does not address this opposite, widespread BCM circuit failure that permanently traps the shifter and disables dashboard monitoring. I request that the federal safety agency investigate this systemic Kia BCM failure pattern for a retroactive safety recall.

On multiple occasions, my 2023 Kia Sorento has experienced an intermittent failure where numerous dashboard warning lights and alerts illuminate and the engine will not start. During the failure, the brake pedal becomes very stiff and the vehicle cannot be shifted out of Park. The problem is unpredictable and has left the vehicle disabled. The vehicle was taken to a Kia dealership for diagnosis. The dealer initially stated that the battery was not properly secured and was moving around, possibly contacting nearby electrical components. They told me the issue had been repaired. However, when I returned to pick up the vehicle, the exact same failure occurred again in the dealership parking lot before I was able to leave. The warning lights came on and, after the vehicle was turned off, it would not restart. The dealer has therefore been able to directly observe the repeated failure. The exact component causing the malfunction is still unknown. I am concerned that this may be an electrical or grounding issue and that the vehicle could become disabled unexpectedly while in use.

The engine failed and is now inoperable. The vehicle has been consuming excessive oil since I purchased it in 2022. I have all oil change records and top offs documented. In May 2026 the engine had a total failure, was making excessive noise, was shuddering and vibrating, blowing lots of smoke from the exhaust and then would not start. The check engine light came on. I towed it to Roseville Kia for diagnosis. Kia refused to honor the lifetime warranty under the class action lawsuit, claiming the engineer failure was due to a damaged exhaust valve. The did not complete the diagnosis. They did not follow the federal safety agency engine replacement flowchart past flowchart A because code p1326 was not present. However the flowchart specifies engine noise and failure to turn over qualify the technician to perform flowcharts B and C. Kia is refusing to complete the diagnosis and evaluate the rod bearings for damage, which would likely qualify the engine for replacement under warranty.

The vehicle's original engine suffered severe oil consumption and a blown head gasket, which contaminated the exhaust system. The Kia dealership replaced the engine under warranty but refused to replace the damaged catalytic converter claiming it wasn’t a part of the warranty even though it was consequently damaged. The dealership explicitly stated the vehicle should not be started or driven due to the blocked exhaust, but then did repair and release after I pushed for the catalytic converter replacement. They said I would have to follow up with Kia corporate. They released the unsafe vehicle anyway and I have been following up with Kia customer service for 2 months to request a CAT replacement. While driving, the blocked exhaust caused a severe rattling noise, immediate engine overheating, and complete mechanical engine seizure. The engine completely cut power and locked up while in motion, creating an immediate crash hazard on the roadway. The vehicle is now completely inoperable and will not turn over. This is a severe safety defect where a known blocked exhaust system directly caused catastrophic engine failure while operating.

The Auto Start-Stop System light came on flashing while driving. Vehicle wouldn’t accelerate while in heavy traffic. Pulled over to the shoulder and turned vehicle off. Attempted to start vehicle again and would not start. Had to get the vehicle towed. Positive battery post is loose and screw is tightened as much as possible.

I am writing to report a mechanical failure with my Kia vehicle that occurred on January 19, 2026. While stopped at a red light, my vehicle suddenly shut off and would not restart. Although the electrical lights came on, the engine would not turn over. Because my car was stuck in the middle of the intersection blocking traffic, I had to call 911 for assistance. When the police arrived, the officer attempted to jump-start the vehicle, but it still would not start. A tow truck was then called to remove the vehicle from the roadway. I paid $290 out of pocket to have the vehicle towed to a nearby repair shop. After diagnosing the issue, the shop determined that the starter had completely failed. I purchased the vehicle on May 15, 2023. At the time of the failure, the vehicle had just exceeded the 60,000-mile warranty, leaving me responsible for the repair. I paid approximately $500 out of pocket to replace the starter. Given the short time between purchasing the vehicle and the failure of the starter, I believe this may indicate a defective component.

The car has completely shutdown on 3 separate occasions. It wouldn't start and all the electrical did not work. It started the next day. All this in a span of 5 out of the 8 months we purchased it. The last time, we found the fuse box was burnt when the tow truck showed up to take it to the dealership. The dealership is trying to blame us because we changed the battery after the second time and not honoring the warranty. They are trying to charge us $18,000. The car had already shut down two times before we even changed the battery. We contacted Kia corporate and nothing has been done, but just phone call saying they will call us back after they talk to the dealership. I got so scared for my wife because she was the one driving the car. This is such a dangerous problem with the fuse box. I researched car problems with Kia Sorentos and sure enough other Sorentos have been recalled, but not ours.

While on the road driving at 35 MPH, the vehicle started to "bog" and losing power and/or acceleration. Had to immediately drive off the road as there were several vehicles behind. As soon as driving off the road, the vehicle died down and would not start again. The check engine light came on. After several minutes the vehicle started again and drove to a secure area to call the tow truck. If the vehicle died down while in traffic, it would have caused an accident involving several vehicles. If it happened on the freeway, it would have caused a "major accident". The vehicle was towed to the vehicle dealership. It was determined by the vehicle dealership that the "high pressure fuel pump" was faulty and had to be replaced. It took four (4) months for the replacement part to arrive. Another similar dealer said that there were "55 other vehicle owners" waiting on the same part nationwide. It must be an "inherent problem" with the high pressure fuel pump. After replacing the high pressure fuel pump, the vehicle was operating normally.
