I am submitting this complaint to report two separate incidents involving a sudden and significant loss of acceleration in my vehicle while merging onto the freeway. These incidents created dangerous driving conditions and placed both myself and my children at risk. First Incident â July 2026 In July 2026, my vehicle experienced a sudden loss of acceleration while I was merging onto the freeway. I was traveling uphill in a single-lane merge area with no shoulder available to pull over safely. During this incident, the vehicle would not accelerate beyond approximately 40 mph, and I was forced to maintain that speed for several miles. I had both of my children in the vehicle at the time.…

While driving in our Kia Sorento 2025 on XXX, completely secluded from any other traffic or road hazards, the sunroof exploded outward. The explosion was very loud and startled my wife, who was driving, almost causing a single-car accident. This is the second time this has happened in our family, and KIA is refusing to acknowledge any issue and won't even return our calls. I'm very worried about this causing a serious accident or even death. Glass shop in [XXX] said they've seen it multiple times but can't fix. Kia Dealer in [XXX] (our home) won't cover it under the "bumper-to-bumper" warranty or recall. Please intervene. If you don't, nothing will change and someone will die eventually.…

While driving in a 55mph highway, I lost all accelerative power in my KIA Sorento Hybrid, driving my speed down to 25mph with vehicles behind me and no shoulder to pull onto. When I put my foot on the accelerator, the rmps on the dash would go all the way up 3000-4000 rpms, but there wasn't even a revving sound, and the car would not accelerate. Luckily I had just left my house was able to turn around and drive slowly home with my hazard lights on, the two miles back home. The first moment it happened the car behind me had to break, and luckily did so in time. From looking up the symptoms, it seems it may have been a malfunction with the HPCU. At no time did any diagnostic lights come on to…

The central ccNC infotainment display screen on my 2025 Kia Sorento Hybrid intermittently and now permanently failed (blank/black screen). This total display blackout completely disables the backup camera system (FMVSS 111 non-compliance) and critical vehicle setting controls. The issue first began while under the 36,000-mile factory warranty (documented at 12,000-14,000 miles). Despite providing timestamped video proof and taking the vehicle to the dealership for diagnosis (Case #26311712), Kia America has delayed and refused to authorize a goodwill repair/replacement. This issue mirrors official NHTSA safety recall SC361 / 26V046 for 2025 Sorento display defects.

My 2025 Kia Sorento Hybrid SX-Prestige has repeated issues with the engine and drive train. On December 30th, 2025 it was diagnosed with a blocked breather hose sensor, causing the check engine light to come on. On July 1, 2026, the car rapidly decelerated while driving on the highway (limp mode), creating an unsafe condition, with an alert to charge the battery. The car also seemed to struggle getting up to speed, and shifted gears less smoothly, and at higher engine RPMs than it had previously. The deceleration behavior was confirmed by the Kia Technician. On July 21st, 2026, the car again rapidly decelerated while driving on the highway (limp mode), creating another unsafe condition, but…

This report concerns a repeating loss of power in the 2025 Kia Sorrento-Hybrid that forces the engine into "limp-mode". This issue has occurred when traveling at speeds exceeding 55mph on highway as well as when accelerating to merge into traffic. The vehicle does not flash any warning lights on the dashboard and shuts down in the middle of traffic which presents a serious safety issue for oncoming traffic as the vehicle must coast to the side of the road. This has occurred multiple times and twice I have had the vehicle towed to the dealership. Initially a fuel pressure sensor was replaced and the second time the dealership indicated they could not find any relatable cause. Since that time…
