2022 Tesla Model 3 Speed Control & Cruise Problems

My family and I were in my Tesla Model 3 2022 and heading from Charlotte to Orlando on [XXX]. The car was in Full Self-Drive (FSD) mode while commuting through Daytona Beach. The rain was heavy in the area. While driving in Daytona Beach, FSD caused the car to change lanes and go to a lane that had standing rain puddles on [XXX]. After FSD caused the lane change, the car immediately hydroplaned out of control. The car's short clearance from it's bottom and the ground which traps water that exacerbates hydroplaning, along with its generative breaking feature made matters worse and uncontrollable. The car spun into the median three times and settled in the middle of danger interstate. The car is totalled. My family and I require medical attention and counseling due to the trauma.

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.

NHTSA Vehicle Safety Complaint •Vehicle Information: •Make: Tesla •Model: Model 3 •Year: 2022 •Summary of Incident: On November 28,2024, I experienced an incident involving my 2022 Tesla Model 3 while it was stationary just outside my garage. I accidentally pressed the accelerator pedal instead of the brake. The car surged forward and crashed into the back wall of my garage. Despite Tesla’s advertised safety features, such as Collision Avoidance Assist and Automatic Emergency Braking (AEB), none of these systems intervened or activated during the incident. I expected the safety systems to detect the garage wall and mitigate the collision, but they failed to respond. Additionally, Tesla’s Obstacle-Aware Acceleration system did not seem to function as intended to limit acceleration in this scenario. •Injuries or Property Damage: There were minor injuries to passenger, but the vehicle and the garage sustained significant damage. •Steps Taken Post-Incident: I have contacted Tesla to request an analysis of the vehicle’s event data logs to determine why the safety features did not activate. I am waiting for their response. •Concern: I am filing this report because I believe this may indicate a potential safety issue with Tesla’s collision prevention systems in low-speed scenarios involving stationary obstacles. This raises concerns about the reliability of these features in real-world situations, particularly for drivers who may accidentally press the accelerator. •Supporting Information: If needed, I can provide photographs of the damage, repair estimates, and additional details.

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.

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.

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.

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.

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.

My wife driving our Tesla Model 3. From her report, the car was accelerating on its own and would not stop despite her pressing on the brake pedal. She was unable to stop at the traffic light and crashed into another car at an intersection.

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)

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.

Driving on the freeway 70mph on cruise control. Not auto pilot. No one around us and no warning. Suddenly car applied brakes on its own and dramatically slowed. Good thing there was no one behind us or else there would have been an accident and we would have been badly injured. Monday Jan 1 2024 1:35pm

Please help Phantom braking is getting worse

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.

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).

I was at a stop light. The car was stopped. The car suddenly lurched forward. I put my foot on the break but then it lurched forward again, and rear-ended the car in front of me. It appears that the car accelerated by itself. This caused an accident. The accident happened tonight. I have filed a police report and received a traffic citation for following to close. I have saved the dash cam footage of the incident to a computer and have requested that Tesla send me the EDR data. Looking at the car's logs in service mode I can see that the car was throwing several errors from before the accident with codes of "VCFRONT_a059_inputResistanceHigh," and "DIF_a018_hwLVSupplyUV" relating to the front vehicle controller and drive interface. I am attaching this plus photos of the damage.
