2022 Tesla Model 3 acceleration problems

VEHICLE SPEED CONTROL

Tesla software update 2026.20.6.11 v14 Lite NA-2025.44 removed manual speed control for Full Self-Driving. The driver can no longer set a maximum speed. The vehicle chooses its own speed and it is frequently wrong and dangerous. Curves are the worst failure. The car enters curves too fast. It accelerates through curves. It does not slow to a safe speed before the curve begins. The driver has no way to cap the speed. The scroll wheel is dead. There is no override. Posted speed limits are ignored. The vehicle uses bad map data instead of reading visible signs. It will do 65 in a 55. It will not slow down when the sign says 55. The driver cannot force it to obey the posted limit. Speed control is gone. The driver is a passenger watching the car make bad decisions. This is not safe. This is not driver assistance. This is loss of control. NHTSA must require Tesla to return manual speed control immediately. A human driver must be able to cap the speed at all times. The current software removes that ability and creates a clear safety hazard.

On XXX, while Full Self-Driving (Supervised) was engaged, my 2022 Tesla Model 3 RWD abruptly decelerated without any visible vehicle, pedestrian, debris, or other obstacle requiring braking. Based on my best recollection, this occurred on approximately five separate occasions in clear daylight with clean cameras. On XXX, the first event occurred near XXX while traveling from [XXX] toward the [XXX]/[XXX] area. I took manual control for about 30 minutes. After I re-engaged FSD, a second event occurred and included approximately three rapid braking pulses. The occupants lunged forward during both episodes. On XXX, the drive from [XXX] to the Ukiah Costco was normal. On the return toward [XXX], FSD suddenly braked hard at approximately 63 mph and reduced the vehicle's speed by about 25 mph, to approximately 38 mph. Family members and friends in the vehicle were startled and moved forward. Later that day, there were two additional unexpected braking episodes while traveling from XXX toward XXX. I used accelerator input to override the unwanted braking. The unexpected highway-speed deceleration created a risk of being struck from behind and made the system unpredictable to supervise. No crash, fire, injury, or property damage occurred. I do not recall a warning message before the braking. The vehicle has not been inspected or diagnosed for this issue and is available for inspection upon request. As of XXX, the vehicle reports Tesla software 2026.20.3 and FSD (Supervised) v12.6.4; it has Hardware 3. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased the Full Self-Driving (FSD) package for approximately $10,000 on my 2022 Tesla Model 3 Long Range AWD. Tesla marketed FSD as a feature that would enable autonomous driving capabilities including Navigate on Autopilot, Auto Lane Change, Autopark, Summon, and city street driving - all to be delivered via software updates. Tesla has since confirmed my vehicle's HW3 (Hardware 3.0) computer cannot support FSD as advertised. There is no hardware upgrade path. The FSD Transfer Program that allowed owners to move their purchase to a new vehicle ended March 31, 2026 with no accommodation for affected owners. The system regularly fails to perform as advertised. It requires constant human supervision despite being sold as "Full Self-Driving." I have sent three formal complaints to Tesla's executive team (May 7, 8, and 12, 2026) with zero response. Tesla's own support chatbot confirmed I am not eligible for FSD transfer.

If you are on a hill and you accidently press both the brake an accelerator, the car will fall to neutral and free roll. In whatever direction is downhill. I have big feet. Happened again to me, I bumped the brake pedal (but not enough to apply the brakes to stop) when attempting to pull forwards slowly and my car beeped with the "both pedals detected pressed" alert. and then it free rolled backwards (because I was on an uphill). THIS WILL CAUSE AN ACCIDENT BECAUSE THE CAR IS NOT SUPPOSED TO FREE ROLL BACKWARDS WHEN IN DRIVE, THIS IS A SAFETY PROBLEM. It has been 4 years now, and no action has been taken to adress this software defect. a NORMAL gas car does NOT do this. If you bump the brake in a normal gas car, IT DOES NOT FREE ROLL IN ANY DIRECTION. This is a tesla software problem that tesla needs to promptly fix ASAP!!!!!

I'm not quite sure what component was affected, some module of some sort got water in or near it that wasn't supposed to. It is available for inspection. Yes my safety and others was out at risk. Yes the problem was fixed by service center supposedly. Yes the car has been inspected by the manufacturer. There were no warnings. What happened was on 12/29 I was driving the car and out of absolutely nowhere a bunch of warnings came up including loss of ABS, any and all safety features. And more importantly lost usage of brakes almost entirely when car came to a stop it was grinding and shakey. This problem all arises due to teslas negligence when it came to installing a new windshield on the vehicle. As stated in messages below, they made a mistake while installing my windshield that caused this major issue to arise. They have offered nothing as a solution but saying that their error is supposedly fixed.

VEHICLE SPEED CONTROL

Full Self Driving prominently suggests the user enable “automatic set speed offset”. When enabled it tries to guess the speed it should be going, and goes that speed. On city streets and rural highways the driver is unable to lower the speed with the normal cruise control speed dial. it is disabled. It recognizes when the speed limit lowers on the road, but does not adjust to that new limit. The only option is to hit the brakes or otherwise disable the system. On the interstate this resulted in it resetting to the maximum 85 MPH as it was setting itself to 86 at every deactivation. Turning cruise control back on, despite having previously set it to the speed limit, causes it to to immediately accelerate regardless of the posted limits or the previous setting.

VEHICLE SPEED CONTROL

The noted vehicle is one of 7 Teslas (6 Model 3s and 1 Model Y) that I have rented from Hertz for a round trip from Orlando Fl to Naples Fl. Over the last 7 months. Each of the Model 3 vehicles was different, I never got the same Model 3. Each of the vehicles exhibited the same or similar glitch when traveling on [XXX] at [XXX] when either the navigation and/or the adaptive speed control was engaged and traveling at or near the posted speed limit when nearing this specific exit. If only the navigation system is on it will direct the driver to take the exit and then return to the interstate using the on ramp. If the adaptive speed control is engaged, either with or without the navigation feature on, when the vehicle is on [XXX] near or under the overpass it will abruptly try to slow the vehicle to 35 MPH, the speed limit for traffic on the overpass. None of the rental vehicles has the full autopilot activated to my knowledge. This event will occur when traveling in either direction and has only occurred at [XXX] on my 200+ mile trip. Having this occur once or twice would be strange, but 7 times at the same location over 7 months in 7 different vehicles is more likely a glitch of some kind, and one that could result in a crash if a driver is unprepared for the unexpected rapid reduction in speed. [XXX] is heavily travelled with both local and out of town drivers in both personal and rental vehicles. I have no idea if this is occurring at other locations but it seems to be consistent here. Since the adaptive speed control must be using information from the navigation system to display and utilize the speed limit to regulate maximum speed, it is likely the problem is in the navigation system.

My 2022 Tesla model 3 has a major issue that should be widely addressed and because the computer screen has completely turned off although there was never any damage done to the vehicle. The cost to fix this issue is $3,052.30. I went on a three day vacation and came back to the screen not turning on but the vehicle can still drive, the major issue is that the screen controls all major functions of the vehicle and is a major danger driving the car if you cant see how fast your going, how much battery is left or will basic safety equipment will deploy? How can a vehicle be driven under these basic safety standards and conditions when it’s a faulty manufacturing issue. In addition come to find out that the computer tried to update it’s software with out my consent and causing the computer to fail there fore leaving me in danger situation of driving the vehicle under these conditions and then having me to pay the financial repercussions although I caused no damage to the vehicle.

While driving with the cruise control set, at times the care must sense that there is an issue ahead and slams the brakes on. This has happened on numerous occasions. This had led to cars following to do the same (hard braking). Although this has not caused an accident for me, I don't trust the system. I'm waiting for a rear end collision when this happens.

This car will suddenly slow down for no apparent reason when driving with the speed control set. I have experienced this multiple times at 2 specific intersections. It has also happened at other times but on roads I have traveled on less often. Traffic aware cruise control is always enabled on this car. There isn't an option to turn it off. I scheduled a service visit with Tesla explaining what was happening at these 2 specific intersections (I included the intersection specific information). They responded and said they performed a remote diagnosis on the Autopilot System in the vehicle and its affiliated hardware and all checks came back in good standing with no faults. They went on to state "just as a reminder as Autopilot/Traffic aware cruise control is under Beta, per owners manual, many factors can impact the performance of Autopilot/Traffic aware cruise control components. Autopilot/Traffic aware cruise control may occasionally cause vehicle to brake when not required or when you are not expecting it." They referred me to the owners manual where these warnings/limitations were reiterated. I replied and asked what Tesla was doing to improve this situation. I did not get a response. I am very concerned about this sudden braking/deceleration as it may result in a rear end collision if someone is following closely when it occurs. I believe Tesla should be more transparent about what they are doing to resolve the issue. They should also provide an option to turn off the Traffic Aware cruise control until the issue is resolved.

VEHICLE SPEED CONTROL

After the recent 1-month free trial of FSD, my basic autopilot does not keep speed and will reset the programmed speed. This causes my car to slow rapidly and unexpectedly. This erratic change of speed creates a safety issue on the road due to the car slowing with no warning and without reason. Tesla has evaluated the vehicle remotely and has said it is performing normally despite this behavior just starting with the FSD trial. The previous 2 years of ownership have had no issues. I am told that this is due to different levels of autopilot having different performance and if I upgrade to the FSD this won't be an issue. No warning lamps are present.

The accelerator pedal broke off completely while driving on the highway (this is the second time this has happened). Accelerator pedal felt as if it were stuck when going from full self driving to manual and pedal broke off when more pressure was applied. The car began coming to a rapid stop on the highway due to regenerative braking and I was forced to quickly get to emergency lane, narrowly avoiding other vehicles in the process.

Vehicle has been scheduled for service 4 times to address phantom braking while set to cruise control on highways. Tesla service center continuously resolves the problem remotely stating that there are no faults in the system and it is operating as intended. I’m an airline pilot and my vehicle poses a safety hazard to me and those around me when operating in any autonomous mode.

On [XXX], I was driving from Victorville, CA to Las Vegas, NV on [XXX] northbound. Between [XXX] two incidents occurred. Both incidents involve phantom braking. My vehicle was in autopilot mode, which is essentially traffic aware cruise control. I was traveling at 70MPH and passed a semi-truck. I changed lanes back into the right lane after passing the truck. About 30 seconds later, the car slammed on the brakes. The semi-truck behind me took immediate evasive maneuver and swerved into the left lane to avoid hitting me. There was no obstruction in front of me. The nearest vehicles ahead of me were so far away that I could barely see their tail lights. This was a very unsafe condition. The second incident happened about 40 minutes later. No other vehicles were near me although the sudden braking gave me a scare. There were no warnings, messages, or any indication that the sudden braking was being applied. I was able to immediately depress the accelerator to increase speed and override the autopilot. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Have reported multiple times the safety hazard with the unnacuracy of the mileage given per charge. Vehicle will drain through battery leaving motorist standard. When using self drive option vehicle will not stay in appropriate lanes. Vehicle will overheat on battery and start making concerning sounds while driving. When reported to Tesla they acknowledged the issue but have failed to fix the issues on the vehicle.

I was sitting at a red light with my foot resting lightly on the accelerator. I was completely stopped waiting for the light to turn and suddenly my car began to accelerate quite fast. I had to slam on the brakes which seemed to be malfunctioning. I managed to stop before I hit the car in front of me. I took it to the Teslas service station and was told by their engineer that nothing was wrong with the car. The experience was scary. I no longer feel safe in my car.

NHTSA complaint #11559426 — an unverified report by a vehicle owner.

VEHICLE SPEED CONTROL

This car has demonstrated repeated incidents of moving/driving backwards when it is set in Drive/Forward via the steering wheel control. This was first reported to Tesla in December of 22. Their service center responded that they could not identify a cause or propose a repair. They commented that it was an engineering and/or software problem. I provided them with multiple date/time stamps. videos of the car performing this way. In the interim the car has demonstrated ghost braking at high speed on an empty freeway. A complaint regarding this concern was provided to NTSA and I have not had a response. The car has subsequently repeatedly moved backward when in Drive. I also have videos of these occurrences. I returned the car to the service center for these behaviors and was told that there was nothing that could be done. The service center said that I "canceled" my request for servicing, and noted that in the Tesla service files. I did not cancel my appointment. They refused to examine and service the car. We recently experienced the car steering wheel locking and inableing the wheel to be turned right, during a 3 point parking exit. I took the car in and was told that the problem was a "firmware" update problem. The problem of driving in reverse when the car is placed in Drive has repeated itself in the past 3 weeks, and I again have videos of this occurrence. This in particular is a dangerous action as it can result in a collision or injury to persons. It is a servo-motor and control problem.

Phantom braking continues. This time the vehicle was traveling on an Interstate highway at 70mph, until the phantom braking occured, which caused the speed to drop immediately (within a few seconds) to less than 30mph. This safety problem was extremely prevalent when the car was within its first six months of use. It has improved, but has not gone away completely.

VEHICLE SPEED CONTROL

I have been forced to stop using cruise control on my Tesla Model 3. Over the past few years, the car will repeatedly slam on the brakes for no good reason when I am driving on the highway. I understand this behavior is known as "phantom braking." The car will suddenly and unexpectedly drop speed by 10-20 mph on the highway. I am so worried that someone will rear-end my vehicle that I cannot use cruise control anymore. For some unexplained reason, the Tesla Model 3 does not currently have a "dumb" cruise control that I could use instead.

I took a recent road trip of 1,200 miles across the southwest. Numerous times while using adaptive cruise control the vehicle suddenly and violently braked for no apparent reason. This was particularly concerning when passing trucks. One particular event was on interstate 5 when passing a big rig truck, I was along side the truck with a following car tailgating me, my car suddenly braked hard, creating a risk of rear end collision at 70 miles per hour. I was able to accelerate to avoid a collision. I did not keep track of the number of events of sudden unanticipated braking, but I would estimate more than 50 instances. They vary from momentary slow down to violent sudden breaking.

We took our first long-disance trip (Albuquerque NM to Arlington TX, round trip) in our 2022 Tesla Model 3 and experienced multiple (4-5) phantom braking episodes to and from Arlington when engaging adaptive cruise control or autopilot. The car had been driven 5,760 miles before the trip. There were no warnings before the braking. The car was travelling at 70-77 mph on interstate highways and suddenly the brakes would engage slowing the car to 40 or 50 mph before we pressed pressed the accelerator. It was a clear day with temperatures in the 90-100 range. One time the phantom brake episode occurred while passing. Fortunately, there no cars travelling close behind us or there could have been a serious multi-car accident. We contacted Tesla service and they told us the car had no discernable problems (attached message).
