Traveling WB on SR100 approximately 60mph after picking up dinner in [XXX] , Before reaching the turn for 302, a deer jumped from the southbound side of the road to the northbound side of the road. When it jumped, the right side of the deer impacted the front of my vehicle which in turn ripped the vehicles hood up from locked down position and slammed it into the windshield. I saw the deers midsection from under the raised hood as the impact happened. I immediately put on my hazards and began to decelerate and pull off the road. I dont understand how my airbags didnt deploy with the damage that was incurred from the deer. In that instant, the side and front collision warning indicators never alerted and the airbags never deployed. The vehicle is being towed to Classic Colision in Daytona Beach FL from Roger's Towing in Bunnell FL Had this been a vehicle impacting another vehicle, my mother and I would not be here as the recalled repaired airbags did not deploy upon impact.

My 2021 Kia Seltos S was not a part of the original recall on Seltos & Soul vehicles. My check engine light came on and now my car has been at the dealership for 3 weeks waiting for a new engine. The front collision will randomly activate when there are NO other cars around. It applies the brakes when you are driving at speed on the highway. Luckily no cars were behind me. My seat belt has also malfunctioned. I connect it and the warning light keeps beeping & flashing even after I try repeating the process. This KIA is a keyed Kia. And although Kia has recently created an Anti-theft software update, that comes about 14 months too late. My car was stolen in Jan 2022. This morning I hear that Kia is having exploding air bag issues. Don't know which models are affected yet, but it would not surprise me if my car is included. I do not feel safe driving this car with all of the safety issues I have.

Today 9/7/2022 I was driving down a hill going about 55mph, when all of a sudden the car started jerking all of the warning lights on the dashboard came on (ABS, ACC, AEB, BSW, FCW, LDW, and the LKA). So essentially all the cool features. The vehicle then popped up a warning decrease speed immediately. Ever since then the car is like in a limp mode thing where it will not allow me to drive over 35mph. It continually jerks, and shakes. It stutters. Absolutely ridiculous. I haven't even had this car long enough to make the first payment. It feels like the back wheels lock up while driving, I'm not sure if they are but it feels like it. If I weren't in debt 40k on a car that's worth about half that (yes the dealership screwed me over). The guy I purchased from (mind you this is at a kia dealership) he is no help he refuses to answer me. I even called the main store to get ahold of him, and he refuses to talk. The service department refuses to help. I will NEVER buy another kia. This is my first and definitely last. At this point I honestly don't even know where to take it to get it fixed because they're the only kia dealership within about 100mi.

My kia seltos with only 900 miles has done the following twice: when at a stop and I step on the gas the car turns off. The first time it happened I was at a stop light and when I stepped on the gas the car turned off and took a couple of minutes before I was able to turn the car back on. The second time it happened I put the car in reverse and stepped on the gas and it turned off. I was told by the dealer that it appears to be a problem with the engine control unit. Now my car has been in the shop for 15 days so far with no knowledge of when the car will be returned because the part is on "back order". I'd like to add that while at the car rental place I met another person with the same car and exact same issues.
