2023 TESLA MODEL 3 Complaints

While driving on 15 freeway between Riverside CA to Las Vegas NV, I put the car in cruise control. While near Barstow, the car hard brakes dropping speed quickly. Luckily no other car was near. I changed lanes to pull on the side as I wasn’t sure what was happened, as it actually felt like the car had locked up. I did take the car out of cruise control and that seemed to fix the problem. I’ve used cruise control before and the adaptive braking has been manageable, this was extreme. On 4 June 2023.

When adaptive cruise control is engaged, the vehicle harshly brakes. This occurs very randomly and is abrupt. The operator needs to quickly take control and accelerate as the speed is reduced significantly. One incident, the speed was 80 mph and it reduced to less than 60.

While in cruise control, the car suddenly reduced its speed; there is no obstacle in the path of the cat that would warrant such an action. This deceleration is sudden and violent and when it happens is dangerous for following drivers.

On a clear sunny day driving on the freeway at 75mph on a 70mph speed limit, the regular cruise control(not Autopilot) was engaged. Experienced 4 separate incidents of strong emergency brakes being activated by the vehicle automatically for 2-3 secs, dropping speed by 10-15mph. As the driver I disengaged the cruise control by strongly accelerating the vehicle. Also multiple incidents of brakes engaging slightly for 1 second , always when driving on a straight freeway, with zero other vehicles present in the front or rear. The road had a slight incline then a slight decline. Just as the vehicle reaches the top of the incline the brakes activated. No warning lamps of sounds, just immediate sharp braking one all incidents. As the driver I felt very unsafe, and glad there were no vehicles close behind, which could have resulted in a rear collision. Vehicle has not been inspected by any party. As a Tesla driver I do not trust the Standard Cruise control feature any more.

Software Version: 2023.12.10 Over the past month, I have experienced a recurring problem with my vehicle's auditory notification system. The issue first began a couple of software updates ago and has persisted through the most recent update. The problem manifests sporadically, having occurred three times within the past month. When this issue arises, all system sounds, excluding radio and media, cease to function for the duration of my ride and persist across all future rides until the vehicle is hard rebooted. There are no visible warning signs or error messages on the dashboard to indicate that the system sounds are malfunctioning. Proof of issue - https://youtube.com/shorts/VbDErQVVzp4?feature=share The malfunctioning system sounds include but are not limited to: 1. Forward Collision Warning Sounds 2. Seatbelt Warning Sounds 3. Blinker Indicator Sounds 4. EV Reverse Sounds 5. System Notifications 6. All alerts and warnings Attempts to Resolve the Issue: To temporarily rectify the issue, I performed a hard reboot on the vehicle's system. This measure restored the sounds, but the problem consistently returns. **Safety Concerns:** This issue poses a significant safety concern as the lack of audible notifications increases the risk of accidents, particularly due to the absence of forward collision warning sounds, seatbelt warning sounds, and blinker indicator sounds. Additional Observations: It is important to note that this issue began a few software updates ago and has persisted despite subsequent updates. There are no error messages or warnings on the dashboard when the auditory system malfunctions, making the problem harder to detect until an auditory notification is expected but not heard.

2023 Tesla Model 3- Consumer wrote about comparison of braking mode to non-EV's, experience driving a rented EV (Electrical Vehicle) w/ braking mode and suggestions to make EV's braking mode safer. When EV's accelerator is NOT pressed the EV goes into regenerative braking mode. No brake lights are triggered because brake pedal wasn't pressed. Consumer listed two "real world dangers". Consumer recommendation- The regenerative braking of EV's should also trigger brake lights notifying vehicles behind the EV that the pace of the vehicle is slowing with the same force. as if brakes where applied.

Vehicle breaks suddenly for no reason under a variety of circumstances. there is no pattern I could identify. i went on line to see if there is an update. many others with the same problem. Very dangerous if there is a car behind. Happens every day or so at freeway speed. Tesla needs to fix this!

When driving and using “autopilot” or just cruise control, the vehicle will randomly brake. Sometimes it brakes lightly, but sometimes it will violently slow the vehicle down, without warning. There is no obstacle in front of the vehicle. If another vehicle is behind the car when the car randomly brakes, this can potentially cause a rear-end event or potentially cause the car that is behind to swerve to avoid an accident. I submitted a service request to Tesla, but Tesla responded by stating that there was no malfunctions that needed to be addressed. They described various scenarios in which the computer would determine a need to brake.

While crossing the rump and side walk to garage the car, as usual slowly proceed to enter the Garage but immediately the car went into extremely fast speed by itself and hit the side of the Garage, damaged the Garage wall, The garage opener, the cabinet, then hit the water softener and our other car in the front. It also smashed the bike against the wall , damaged the side wall cause a bulge to outside of the structure. The garage frame and right side of the Garage door fell on top of the car almost killed our daughter who was at the front passenger seat. The car brake did not stop the car, the alarm did not go off, the air bags did no inflate.

Phantom braking. Traveling highway 5 Southbound between Red Bluff, CA and WIliams, CA at 70 mph, the vehicle suddenly and firmly applied brakes as if attempting to avoid a collision with an obstacle closely ahead. The braking force was enough to activate the seatbelt restraint. There was no traffic for at least a 1/4 mile ahead and behind and no obstacle. I managed to flip the ACC lever up to disable it during the braking but felt that I was losing control of the vehicle. After ACC was disabled normal operation ensued. Speculation: The incident occurred mid-May and the area is agricultural and therefore teeming with bugs that collect on the front of the car. The forward camera may have been hit by a bug and the visual recognition system may have mistaken the bug for a large obstacle.
