2022 Tesla Model Y service brakes problems

“The contact owns a 2022 Tesla Model Y. The contact stated that while stopped at a red light and attempting to accelerate, the vehicle failed to accelerate as intended and jerked. The contact stated that after shifting into reverse(R), the vehicle failed to reverse as intended. The vehicle was shifted to park(P) and then into drive(D) several times, and the vehicle accelerated. The contact stated that approximately 20 minutes later, while exiting the highway and approaching a red light, the brake pedal was depressed and the vehicle was stopped and the hold feature was engaged and the icon showed up on the dashboard, but the vehicle rolled backward and struck another vehicle. The vehicle was then shifted to park(P), and after speaking with the other driver, the vehicle was moved to the closest parking lot. The Police were called, but a report was not filed. The vehicle was then taken to the residence. The vehicle was taken to a dealer; however, the failure could not be duplicated. The vehicle was then taken to the same dealer, but the failure could not be duplicated. The manufacturer was notified of the failure. The failure mileage was approximately 63,500.”

“FSD (Supervised) was engaged while the vehicle was traveling toward a freeway entrance. The vehicle was expected to turn right, but instead began veering left. The driver applied the brake in an attempt to slow the vehicle and disengage FSD. According to the driver’s recollection, the vehicle did not respond as expected and continued accelerating until it left the roadway and crashed into a ditch. The incident created a serious safety risk to the driver and an infant passenger. Emergency services responded, and the driver and infant passenger were transported to an emergency department for evaluation. The vehicle was subsequently towed from the scene. The suspected malfunction involves FSD/vehicle control behavior, including whether the system properly responded to brake input and whether commanded acceleration continued after the driver attempted to intervene. The vehicle and its electronic systems should currently be available for inspection, and a request has been made to preserve relevant vehicle telemetry, driver-input data, FSD engagement status, accelerator and brake inputs, commanded motor torque, speed, steering inputs, camera footage, Event Data…”

“I was driving at approximately 30-35 mph on a 30 mph residential road with my son in the front passenger seat. My vehicle unexpectedly collided with a parked, unoccupied car on the right side of the road, impact occurring between my front passenger side and the rear driver side of the parked vehicle. Following the initial collision, the vehicle continued past a small tree, mounted the sidewalk, and struck a second parked car before I was able to manually bring it to a stop 2–3 houses further down near an intersection. Throughout this sequence—with the vehicle traveling at ~35 mph—neither the Automatic Emergency Braking (AEB) activated nor did any airbags deploy. Fortunately, neither my son nor I sustained catastrophic injuries, though my chest struck the steering wheel during the impact, causing ongoing pain my and mental trauma for my son. I am currently receiving medical advise. Given the speed and sequence of impacts, it is terrifying that the vehicle’s primary safety systems failed to engage before, during, or after the collision. I am seeking a thorough technical investigation into why Automatic Emergency Braking and airbag deployment failed in this scenario with Tesla Model Y”

“**Incident Report — Tesla Model Y Safety System Failure** The subject vehicle, a Tesla Model Y equipped with Full Self-Driving (FSD) technology and advanced safety features, was involved in a collision at an estimated impact speed of 40–45 MPH. The vehicle's onboard recording system captured the incident and clearly documents the impact dynamics, vehicle speed at impact, and the contributing actions of the other party involved. **Incident Details:** - **Impact Location:** Left front side of vehicle - **Impact Speed:** 40–45 MPH - **Damage Assessment:** Vehicle declared total loss by insurance - **Recorded Evidence:** Onboard system footage available **Safety System Failures:** Despite the severity of the impact and speed involved, the following safety systems failed to activate: - Emergency braking system did not engage - Forward Collision Warning Failed - Seatbelt pre-tensioning/locking mechanism did not activate - Airbag deployment systems failed (front, side, curtain, and knee airbags) **Concern:** The vehicle's advanced safety features—which are primary design components marketed for collision mitigation—did not function as designed or expected. Given the…”

“Our 2022 Tesla Model Y long range had a braking system failure due to a flawed routing of the rear flex brake lines. When applying the brakes at a red light the vehicle rolled into the intersection despite the brake pedal being pressed to the firewall. There were no warning lights at this time. After arriving home, large amounts of brake fluid were visible under the car. I removed the rear passenger side wheel to inspect the source of the leak. It was immediately clear that the flexible brake line was the source of the leak. It was installed (at the factory) in a position that allowed it to rub against the thin and abrasive edge of the wheel well. Over time, this cut into the brake line until a hole formed. The same issue was occurring on the rear driver side brake line. I took the car to a Tesla service center where they insisted that this was not a Tesla issue. They claimed that the faulty routing of the brake lines must have occurred within the last three weeks, and that they had never heard of this happening with another Tesla. Only after they looked at the problem did a brake warning appear on the screen showing there was a problem. I paid an independent…”

“I am reporting a serious safety concern involving my Tesla Model Y. While driving, the vehicle’s main center screen (MCU) suddenly failed and entered a continuous reboot loop. This resulted in the loss of critical driving information and controls, including navigation, camera display, and vehicle system status. The issue occurred without any warning and nearly caused a serious accident, as I was unable to safely monitor essential driving information. This failure made the vehicle extremely unsafe to operate. The problem appears to be related to a known MCU system failure affecting some Tesla vehicles. I am concerned that this issue may present a broader safety risk for other drivers. Please investigate this matter for potential safety defects.”
