The car's transmission became unresponsive and caused the car to lose the ability to accelerate. This happened twice on the highway before I could get it to the dealer. In order to recover, I had to pull over on the shoulder and turn the car off, wait, and turn it back on. The dealer, through the Kia warranty service, would only 'recalibrate' the transmission and refused to service it. After the recalibration, the dealership wanted to give me back the car. I insisted that they took it for an extended test drive in which it stalled for them as well. Kia warranty then authorized the replacement, and I am awaiting its completion.

I would welcome making my vehicle available for inspection on this issue. Year/Make/Model: 2023 Kia Sportage EX HEV AWD 4-Door SUV Color: Black Powertrain: Hybrid Electric Vehicle (HEV) Number of occupants: 2 (driver and passenger) Injuries: None, but fatalities could have occurred. Vehicle turned off completely – no power, no hazard lights, and although driver miraculously made it to the shoulder, most of it was blocked by a snowbank and sat in a dead car with no hazard lights. Passenger (recovering from leg surgery in full leg brace) was forced to exit onto a snow bank and enter a tow truck cab, risking re-injury. Crash: No — vehicle was somehow brought to shoulder and aid protected by two state trooper vehicles until a tow arrived. Our car suddenly emitted a loud alarm at highway speed on I-84 -the instrument panel displayed an "stop vehicle immediately" warning. There was no prior warning, unusual noise, or dashboard indication of any problem. The car shut completely down while still on the highway. Car was towed to the nearest KIA dealer - Columbia Ford/Kia [XXX] ). After diagnosis, the authorized Kia dealer documented the following on Repair Order Invoice W7403: • Concern: "TOW IN. DIED WHILE DRIVING. SEPARATED" • Diagnostic fault code: BMS P1BB20 • Failed/replaced parts: ◦ DECOUPLER-BASFILTR, Part No. SPO 25290 2MHD0 ◦ BOLT-CRANKSHAFT, Part No. KIA 23127 2MHA0 ◦ BATTERY MODULE ASSY, Part No. SPO 37507 L5000 • Parts total: $835.54 • Vehicle in dealer possession: March 5, 2026 – March 20, 2026 (15 days) complete loss of motive power at highway speed. Based on my subsequent research, this failure mode appears consistent with a documented similar issue in the United Kingdom and European markets - which did result in a recall. -hybrid belt/tensioner system. Kia issued revised parts and ECU updates in those markets. No equivalent safety recall or consumer notification has been issued in the US.

Often hesitates when accelerating. Stalls from stopped position. LCD Screen changes by itself. Drops calls. Turns off if you make volume adjustment. Most recently, filled gas tank with full tank, just over 13 gallons. Gauge read only 1/2 tank and showed I had only 289 miles rather than normal 520 miles or so. That number kept changing throughout the next couple of days. ATTACHMENTS: show gas receipt at gas station that tank is filled. Gauge shows 1/2 tank. See subsequent photos. Safety issue for sure. This car cannot be trusted. Multiple problems with electrical system and engine stalling.

When starting car from behind stopped, the car would not speed up when pressing gas pedal and felt like stalling, but slamming on gas pedal jolted car to speed up again. If there were cars around, this could have been very dangerous. Car is in the shop now for mechanics to determine exact cause.
