2023 Tesla Model Y problems

“I am reporting a serious safety-related malfunction involving my 2023 Tesla Model Y, which has approximately 55,000 miles. The incident involved multiple vehicle systems, including the front drive motor, propulsion system, traction control, stability control, steering assistance, and braking-related functions. Prior to the incident, I noticed a water-sloshing sound coming from underneath the vehicle, possibly near the rocker panels, following heavy rainfall. After driving for approximately five minutes and parking, I received multiple warning messages indicating that traction control, stability control, and automatic emergency braking were unavailable. Approximately two hours later, I returned to the vehicle, and the warnings had temporarily disappeared. However, about halfway through my next drive, multiple warnings suddenly reappeared, and the vehicle’s driving and braking behavior changed significantly. The regenerative braking stopped functioning, causing the vehicle to continue rolling when I released the accelerator instead of slowing down as expected. When I applied the brake pedal, I experienced unusual vibrations, increased braking effort, and abnormal…”

“I was backing out of a parking spot and as I shifted to driving forward I heard a loud bang from the front driver's side wheel well. I got out to see what had happened, expecting a flat tire, but nothing visually appeared wrong. So I got back into the vehicle and started to drive away again, I could drive straight or turn left, but if I tried to turn right it made loud grinding noises. I slowly drove around the parking but quickly determined the vehicle was unsafe and undriveable at that point. Additionally, I found a large bolt on the ground near where I had driven the vehicle. I no longer have the bolt, because the service center kept it. I arranged to have the vehicle towed to a local Tesla Service Center where they discovered "the front left lower lateral link bolt was missing and the remaining bolt was loose". After having the vehicle repaired, I discovered that this exact issue has been documented and resulted in NHTSA Recall Campaign 22V895000 / Tesla Bulletin SB-22-31-002 (improperly torqued lateral link fasteners). I requested a refund for the towing and repair cost, but was told that there are no active recalls on my VIN. I believe the scope of the…”

“The contact owns a 2023 Tesla Model Y. The contact stated that while pulling into a parking space with the brake pedal depressed, the vehicle unintendedly accelerated and struck an occupied parked vehicle ahead. Upon shifting into Reverse (R), the failure recurred, causing the vehicle to strike the front bumper of a parked and unoccupied USPS truck, which then struck a parked, unoccupied vehicle. The contact engaged the electric parking brake to stop the vehicle. The contact stated that the forward collision avoidance system failed to engage to prevent the collisions. The front driver's side air bag failed to deploy as expected. The vehicle sustained rear-end damage. The vehicle was towed to an auto collision center, where a superficial diagnostic inspection was performed, and the contact was informed that no failure was found. The manufacturer was notified of the failure and referred the contact to a Tesla Service center and to the NHTSA Hotline for assistance. The failure mileage was 30,616.”

“On September 13, 2026, my 2023 Tesla Model Y (13,300 miles) displayed a High Voltage System alert stating the vehicle may not restart and service was required. I brought the vehicle to the Tesla Service Center for diagnosis. The technician found the alert occurred when the brake pedal was applied and identified electromagnetic interference affecting signal integrity in that circuit. On September 17, 2026, a ferrite suppressor was installed to address the interference, and the technician noted the alert cleared. He advised that if the concern returned, replacement of the CHMSL (Center High Mount Stop Lamp) may be required. The same day I picked up the vehicle after this repair, the High Voltage System alert recurred. Both occurrences happened while the vehicle was operating under Full Self-Driving (FSD), not under manual braking. My foot was not on the brake pedal either time. This detail was not accounted for in the original diagnosis, which was based on manual pedal actuation as the trigger. I have raised this discrepancy with Tesla and requested a re-diagnosis based on FSD-commanded brake actuation, including review of vehicle logs for both incident…”

“Noticed a clunking noise from the front of car. Put in a service request via the Tesla app. It said it was fin to drive and made an appointment for 2 weeks later. 1 week later, there was a very loud noise and settling of the car. 2 bolts were on the ground and the left front wheel lost steering control. The bolts secure the lower control arm. This would have been catastrophic if it had occurred while driving.”

“The contact owns a 2023 Tesla Model Y. The contact stated that while the vehicle was parked, the Full Self-Driving software was downloaded and caused the computer to become inoperable. The contact associated the failure with NHTSA Campaign Number: 25V002000 (Back Over Prevention, Electrical System); however, the VIN was not included in the recall. Additionally, the contact associated the failure with SB-25-00-001. The dealer was contacted. The contact requested a complete diagnostic log from the dealer. However, the dealer had not provided the full log or accompanying pictures due to proprietary terms and conditions. The manufacturer was contacted by phone and made aware of the failure. The failure mileage was approximately 67,000.”
