At any speed period, if i hit a pothole or those little ripple things on side of the country county roads, any of them causes my vehicle to jerk and makes a a sound like the entire right front end is going to fall apart at any moment and it either jerks my vehicle off the road on the right side or it either jerks the vehicle into the opposite lane towards on coming traffic. My truck has caused me to go completely off of the highway into the grass to avoid a collision...and anytime I hit the most tiniest of bumps it sounds Like the entire right side suspension is going to fall completely off and at high speeds it shakes uncontrollably...

I am the original owner of a 2010 Hyundai Santa Fe. It currently has less than 100,000 miles on it as I drive it infrequently. On June 12, 2023, my airbag light lit on the display and has since remained. I immediately contacted the local Hyundai dealership and made the next available appointment. I was concerned because I had recently completed the Knock Sensor Detection System (KSDS) service campaign on 4/3/2023. Initially, I took my vehicle to an auto repair facility where a diagnostic test determined my SUV had a B1620 error code and was advised to take it to a Hyundai dealership. My Hyundai appointment was on 6/23/2023. I shared the information about the error code with the technicians. The dealership confirmed I had a B1620 error code where the Supplemental Restraint System Control Module (SRSCM) shorted out. I also showed the dealership employees an Extended Warranty Notification letter I received from Hyundai about faulty clock springs, but the dealer stated the module was completely separate and not part of the recall. The repair estimate was quite costly at around $2,600. From my understanding, the SRSCM controls all safety features. The dealership informed me the air bag light/error code means my entire safety system is completely disabled. This is not a mechanical issue but rather a safety red flag.
