2023 TESLA MODEL Y Complaints

The adaptive cruise control system routinely applies the brakes when there is no lead traffic on a completely open highway. I’ve had multiple instances where the car decelerated from 75 to 45 mph before I could react and press the accelerator to correct the state. During these events, the car does not indicate any type of emergency warning (no forward collision warning, no emergency braking warning). This poses enough of a safety risk to cars behind me that I will no longer use Tesla’s adaptive cruise control feature.

The adaptive cruise control slammed the brake when driving over a highway overpass. Tesla slammed the brake from 75 mph to 50 mph. Luckily there was no car behind. Clear sky around noon time.

While driving South on I75 near Tampa Florida using Autopilot the car suddenly decelrated to 10mph. There were no cars next to me and we were passing through a 6 lane area where the road splits. No distinguishing features, no cars on either side and we were heading slightly up hill. It seems like the cameras could only see the sky. Fortunately there was no car directly behind me. Very scary.

The contact owns a 2023 Tesla Model Y. The contact stated that while driving approximately 62 MPH with the autopilot mode activated, the vehicle experienced phantom braking. There were no warning lights illuminated. The manufacturer was not made aware of the failure. The vehicle was not diagnosed nor repaired. The approximate failure mileage was 3,000.

This is the second instance of this issue happening, first at 1800 miles ODO, and second at 4690. Both instances, when driving, the vehicle suddenly and violently shuddered to a stop. The first instance happened as I pulled out from a stop sign to take an unprotected left onto a street. In the middle of the intersection, the car shuddered to a stop violently and a lot of warnings and alerts came up on screen. Cars moving both directions had to suddenly stop to not hit my car dead in the intersection. The gear stalk inputs to put the car in drive or reverse and allow function of the vehicle did not work. I pushed the park button on the right stalk and then moved it into drive, which it allowed. I was then able to limp the car out of the intersection (with power vastly reduced and speed reduced) and await a tow. The second instance I had pulled into a parking lot at around the same speed (~15 mph) in which the car again shuddered violently to a stop with no ability to override. Traffic behind me had to brake as to not hit my vehicle which stopped in the middle of the lot. Again the car was inoperable until this time locking and unlocking the car from outside of it and reentering to limp it to a parking spot for tow. Safety of myself and others were put severely at risk suddenly and without warning from the car stopping itself. If this were to happen in other, less fortunate scenarios, risk to human lives is great. Problem has been confirmed by Tesla service center, but not reproduced while in their possession. The vehicle was inspected by Tesla service after the first incident and was explained to have found no faults with any hardware, but found a corrupt line of code in the firmware (no update or firmware change was noted to be available). Warning messages and alerts populated at time of incident and no sooner (no warning is given prior to issue). Alerts include power reduced, rear motor disabled, vehicle shutting down, automatic emergency braking disabled and more.

Tesla model y 2023 phantom braked on the intestate. The emergency braking system and adaptive cruise are not correct. I almost got hit because my tesla auto pilot braked on the interstate for no reason.

Took 1st long trip with the Tesla. I had "phantom braking" happen 5 times while on the trip. Once on the way to the destination. Then, it happened 4 times on the return trip home in a span of 2 hours. This was in the first autopilot mode (Traffic-Aware Cruise Control), not the Autosteer version. Each time it happened on an open road in a rural area at a speed of around 70mph. This puts my vehicle and others at risk where someone that is close behind me would be surprised with a sudden decrease in speed and cause an incident. It also is nerve-wracking to the driver and passengers of the vehicle. This problem is known within the Tesla community and was reported to Tesla. The vehicle was "inspected" by looking at incidents in the cars software log. The Customer Service agent could not confirm any incidents and asked that I file a "bug report" through the car immediately after it happens again. There are no symptoms or warning of the problem - it happens at random.

New car with less than 1800 miles. Multiple times where The car will frequently and unexpectedly slam on the brakes while in autopilot on the highway. Almost caused an accident twice and I was terrified. Did not know about this problem but this can cause an accident.

Vehicle displayed alert “Powertrain requires service - vehicle speed and power may be limited” at 1664 odometer miles. Vehicle had to be towed to the service center and the cause was a faulty oil pump.
