I am getting an electrical fault which has disabled my front passenger seat airbags. They need to replace the wiring, which means they also now need to replace the passenger airbag itself because wiring has changed and the old airbag is not compatible with the new wiring. Replace Occupant Classification System (OCS) of Front Passenger Seat while Servicing Subcomponents Update Front Passenger Airbag to Maintain Compatibility with Front Passenger Seat I had this same error 4 months ago and it ended up shorting out the entire electrical system, which disabled autosteer and eventually completely disabled power steering which made the car unusable. Tesla service center called it a water intrusion problem and had to replace the entire front electrical harness system and steering rack costing $4500. Now the problem has resurfaced and I'm afraid I might lose power steering again which is extremely dangerous and could happen any time, in addition to my airbags potentially not deploying.

Loss of power steering by model year
What owners say
While driving, the front driver-side suspension collapsed due to a complete detachment of the front lower lateral link. The fastener (bolt) backed out entirely and fell onto the road/under-shield. This matches the failure mode described in the federal safety agency Recall 21V‑835, although Tesla has previously claimed my specific VIN was not included. The failure caused an immediate loss of steering control and structural instability. I am reporting this as a potential 'recall bypass' where the defect exists outside the currently identified recall population
At approximately 30,000 miles, the front left suspension lateral link/control arm separated while driving due to a missing mounting fastener (bolt), resulting in sudden steering instability and abnormal front wheel movement. Vehicle handling became unpredictable and felt unsafe to control, creating risk of loss of steering control. I stopped driving immediately. There was no collision, curb strike, pothole, or road hazard at the time of the incident. No warning lights or messages appeared prior to the failure; it occurred suddenly without advance notice. Tesla Service inspected and confirmed the separation and missing fastener. Suspension components and the front subframe assembly were replaced —$4,400 out of pocket. Tesla documented they could not make a formal cause determination. The recovered bolt is intact and available for inspection upon request. Insurance also reviewed the incident and classified it as mechanical rather than collision-related. Because this involves a safety-critical steering/suspension fastener failure without warning, I am submitting this report for safety tracking. I am aware of similar owner reports describing suspension fastener or lateral link separation on this vehicle generation in case this reflects a broader pattern.
What component or system failed or malfunctioned, and is it available for inspection upon request? The steering system failed due to corrosion and water ingress affecting both the steering rack and the associated steering wiring harness. These components were replaced by Tesla and are no longer available for inspection. How was your safety or the safety of others put at risk? The steering system is a safety-critical component. Corrosion and water intrusion created a risk of reduced or sudden loss of steering assist while driving, which could lead to loss of vehicle control and increase the risk of a crash. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Tesla service confirmed water ingress and corrosion affecting the steering rack and wiring harness and performed a full replacement of both components. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle and steering components were inspected by Tesla at a Tesla Service Center, which identified water ingress and corrosion as the cause of failure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The vehicle displayed steering-related warning messages prior to repair, including reduced steering assist alerts, which prompted inspection by Tesla service. The warnings appeared shortly before the repair was performed.
"Steering assist reduced" Error code UI_a020 Losing steering power mid-drive due to faulty power steering rack Many others have had this issue happen to their Tesla Model 3 and Ys, i would like to know if this is covered under a recall as my car is out of warranty for this type of safety repair happening very prematurely for a car

Steering: automated/adaptive steering
- What is wrong
- Tesla, Inc. (Tesla) is recalling certain 2016-2023 Model S, Model X, 2017-2023 Model 3, and 2020-2023 Model Y vehicles equipped with Full Self-Driving Beta (FSD Beta) software or pending installation. The FSD Beta system may allow the vehicle to act unsafe around intersections, such as traveling straight through an intersection while in a turn-only lane, entering a stop sign-controlled intersection without coming to a complete stop, or proceeding into an intersection during a steady yellow traffic signal without due caution. In addition, the system may respond insufficiently to changes in posted speed limits or not adequately account for the driver's adjustment of the vehicle's speed to exceed posted speed limits.
- Risk
- FSD Beta software that allows a vehicle to exceed speed limits or travel through intersections in an unlawful or unpredictable manner increases the risk of a crash.
- Remedy
- Tesla will release an over-the-air (OTA) software update, free of charge. Owner notification letters were mailed April 15, 2023. Owners may contact Tesla customer service at 1‑877‑798‑3752. Tesla's number for this recall is SB-23-00-001.
