3 separate times the right pillar camera and 2 times for all cameras: The car's computer lost contact with the cameras and could not reconnect. In 2023, Tesla changed from radar to camera sensing technology. All driving functions relating to car positioning and cruise/speed control were lost at those times. Twice the car was under cruise control so the car interpreted this as 0 mph and initiated emergency braking from 75 mph on an interstate highway. I was able to avoid the following cars hitting me only by instantly accelerating back to posted speed. Tesla has been very difficult to convince that this is a problem. They say that remote diagnosis is inconclusive. Since they go for "at home" service first, 3 separate service times were cancelled by them, and they will not allow a service appointment at their shop for further diagnosis. …
This complaint is about difficulties with the horn sensor on the steering yoke under emergency situations. After 14 months of driving the car, I have these safety issues: 1) The horn sensor is difficult to find in emergency situations. It is a single, small area located farthest away from the right-hand rest position and touching it requires a long stretch with the thumb. When turning, it is easy to lose the orientation of the yoke and nearly impossible to find the horn sensor. (See #5 in the attached image). 2) The horn sensor is near the cruise-control button ("right scroll button"). The cruise-control button is raised and I have accidentally engaged the cruise-control on multiple occasions when trying to reach for the horn sensor. I would lift off the accelerator, expecting to slow down, but imagine my panic when the car speeds-up due to the accidentally engaged cruise-control. …
We took our first major road trip in our new 2022 Tesla Model S on Friday 10/14, leaving at 10:00 am for a 9 hour trip. During the trip the car experienced multiple severe incidents of the car braking hard while at highway speeds and two of the incidents almost caused an accident. The car drops 10 to 15 mph instantly for no reason. We drove the car home on Monday 10/17 without AEB, Auto Steer, FSD Beta, Emergency Lane Departure Avoidance and Obstacle-Aware Acceleration and used TACC occasionally and still had the issue but wasn't as severe. …
I have used the self driving feature of my 2022 Tesla Model S on several highway trips, most recently a round trip between Seattle and Palm Springs. The following problems with the Tesla self driving feature were noted. (My car has only the basic self driving feature, not the full self driving upgrade) 1. Random "phantom braking" where the car, without apparent reason, suddenly braked. 2. On several occasions the car abruptly swerved off toward an off ramp. I think this occurred when the white line marking the side of the road was interrupted by the off ramp where there was no painted line. 3. On several occasions when the turn signal was activated in order to change lines the car started to move over into the adjacent lane but abruptly swerved back to the original lane. I was able to maintain control but it was a frightening event. …
The contact owned a 2021 Tesla Model S. The contact stated while driving approximately 100 MPH, as he took his foot off of the accelerator, with the vehicle brake control set to "aggressive slowdown," as the vehicle slowed the contact looked into the rearview mirror and observed white smoke issuing from the rear of the vehicle. The contact then depressed the brake pedal, and instead of slowing the vehicle accelerated at a dramatic rate and the contact lost control of the vehicle and left the roadway. The contact stated he was not aware of any warning lights being illuminated. The vehicle went into a ditch and continued straight following the ditch. The contact stated that the vehicle had not lost any speed, rather it seemed to be going faster. The vehicle crashed through a fence, drove up a slight berm, and went airborne. …
The contact owns a 2021 Tesla Model S. The contact stated that while driving at various speeds with the cruise control feature engaged, the brakes independently activated without the brake pedal being depressed. No warning light was illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 65,000.
In all assisted driving modes except Full Self Driving (FSD), the car properly displays the speed Limit it has determined either by Map data or visual confirmation. In FSD, apparently only on pre-2021+ Model S cars, the determined speed limit is not displayed. In my town we have a US60 route. The car sees these signs and determines the speed limit is 60, even though it is only 35. The driver notices a rapid acceleration and may observe the set FSD speed has changed to 60. There is no Speed Limit displayed in this mode. Very dangerous to go this fast on a 35 MPH road. When not using FSD, the car does show this error in the speed limit as being 60, even though the car determined speed limit itself is in error.
The latest tesla update has caused significant increased number of "phantom breaking" episodes when using just cruise control on state highways. I had at least 10 episodes on my last 100 mile drive (not using autopilot, just cruise control). Worst events caused rapid breaking from highway speed of 65 mph down to 40-45 mph with warning messages and audible alarms. Non of the events needed breaking. The worst two events were on straight sections of road with no oncoming traffic or other potential obstruction. I do not feel safe using cruise control on the freeway.
NHTSA investigations
Sudden Unintended Acceleration
The Office of Defects Investigation (ODI) received a petition requesting that ODI reevaluate its decision to deny DP20-001 on the basis that intermittent high electrical current demands on the vehicles' 12VDC systems may have caused some or all of the incidents examined by ODI in DP20-001. The petitioner bases this information on a review of open-source research and the DP20-001 denial.
Frequently asked questions
Which Tesla Model S years have acceleration problems?
By NHTSA complaints, the 2016 (81), 2015 (40), 2017 (35), 2018 (28) and 2013 (25) model years. Acceleration complaints make up 13% of all complaints for the 2016.
Is there a recall for Tesla Model S acceleration problems?
No. NHTSA lists no speed control & acceleration recall for any Tesla Model S model year. A widespread problem may still be covered by an extended warranty or a manufacturer service bulletin, so ask a dealer.
At what mileage do Tesla Model S acceleration problems start?
Across all years, half of the complaints with a recorded mileage happened before about 16,000 miles; 82% happened before 50,000 miles.
What part fails most often?
Owners most often name the accelerator pedal (1 mentions), followed by the cruise control (1).
