NHTSA Complaint #11515984 — 2012 KIA SOUL

The series of events leading to my theory of what is wrong with my 2012 Kia Soul: 1. Steering coupler replacement in March of 2021 left my steering wheel sideways instead of straight, air bag light remains on, and traction control light as well. The after-market (I assume) cruise control is automatically on when car is started. Must turn off manually. 2. U-joint connecting to steering column fell onto my feet while driving in December of 2021. I slid it back on, but it slipped off approximately 4 more times in the next month before it was strongly secured. 3. Alignment performed in February 2022. Approximately 2 weeks after the alignment, my car started stuttering, if you will, prior to shifting into third gear. Then, again, prior to each shift into the higher gears. It stalled a few times in response to this action. While accelerating, the car begins to jerk severely, as if the brakes are being pumped. It doesn't do this immediately, but only begins once it's warmed up. Several sensors have been replaced. Fuel filter replaced. It's a standard, but the transmission was replaced after I purchased it in 2018. After hooking up to the code scanner at the parts store, the Steering Tilt Sensor is the code shown. My theory is this: When the steering coupler was replaced leaving my steering wheel in the turned position, and then aligning it with it in the wrong position, that threw the tilt code. Maybe it's jerking because it thinks I'm turning when I'm not, and it could possibly be engaging the abs to slow me down while it thinks I'm turning. Would I be wrong in assuming that if I get the steering wheel straightened, get another alignment, and clear the steering tilt sensor, my car will act normal again? I am uncertain what system or part failed, but it is definitely available to be inspected. I could have died when the u-joint fell off if I hadn't been almost to a stop sign every time. The problem continues, but has not been addressed or confirmed by a dealer.
