2012 Hyundai Sonata vehicle speed control problems

“The driver side seat belt wont click and stay in almost half the time i drive my car… after reading other complaints its looking like this is a common thing. Within the past year ive noticed lots of times that when im going to lock my car with my fob, it wont lock and its because the passenger side lock button on the inside of door is in a stuck between lock/unlock position… resulting in me having to lean over to manually unlock the door even when I’ve unlocked my car with both the fob and inside button… all the sudden i noticed too that my speed control will not work at all and be completely unresponsive most times. It will RANDOMLY work when i try checking it on highway. ive had SO many issues with my taillights going/burning out constantly and now my headlights have gotten really dim. Im scared to drive at night now. They are much more dimmer than a cars should look like usually. Within the past week i just noticed a random big crack in the dashboard on the passenger side as well… noticed that seems to be a common thing and concern of safety with lots of others who own and drive this same vehicle… my first thought was “what if this crack will effect the…”

“Daughter was driving her car on interstate, doing 75, in the middle of traffic when the car would jerk and then loose power. The gas petal stopped working and the check engine light would come on. She had to make her way over to the shoulder, without causing an accident. Once car gets shut off and you wait a few minutes, you can start it and drive it home. This has happened about 4 times now. We are lucky that this hasn't caused an accident! This last time (yesterday), the check engine light stayed on and we were able to hook up the dianostic reader and it read the code for the crankshaft positioning sensor A circut. It says online that this is a common problem with that car and is very dangerous. How is this not up for a recall? My daughter is scared to drive her car.”

“When I start the vehicle in the morning I leave the neighborhood going around 15mph and the car loses power. I have to let off the gas completely then reapply but it still continues to studder. I applied the slapstick sift mode and noticed it does this in first and fourth gear. In automatic you can’t see it”

“B pillar separated from the frame during collision causing catastrophic intrusion into the cabin upon impact leading to death of the driver. No other occupants in the vehicle. Multiple investigators noted the B pillar failure upon inspection. Independent, certified crash reconstruction expert also noticed immediately that the B pillar had failed which caused cabin intrusion to an extraordinary degree considering the 2 vehicles involved were going less than 40mph. Vehicle is available for inspection. In addition, edr data reveals that although throttle was engaged, rpm's remained at idle up to the time of impact. Driver pushing on the gas and vehicle not responding.”
