2022 Tesla Model 3: adaptive cruise control problems

Filed Jun 17, 2025 · Brakes, Driver assistance · IL

I was traveling northbound on [XXX} in Sugar Grove, IL with the traffic aware cruise control on. As I passed under [XXX] the car braked heavily for no reason. No cars in the area...thankfully. I could have easily been rear-ended. It has done this on more than one occasion at this location. I filed a "bug-report" via the right hand button on the steering wheel. I was also traveling [XXX] near Lasalle-Peru with the cruise control on at about 80 mph when the vehicle suddenly braked heavily. No cars around at all. The moment was extremely frightening.

I was driving over an overpass on to the free way. It was about 11am. The steering wheel locked in a turning position, driving the car off the overpass. I was able to yank the wheel and get it back straight. The auto pilot was not on, the cruise control was not on. I drove it straight to the service center, i though i should call so i put the car in curise control to pull out my phone but decided against it and turned it off at 11:15. Now the service center says they can not duplicate it they are telling me nothing is wrong. This has never happened before. I have never had any issues with my car.

Hi. My issue is partly related to case PE-22-002 and may also contribute to it as well. I will forward my dash-cam videos (the false detection of cars in-front of me for 63.5% of that drive is included here) to your email as support for the investigations. I have been noticing warnings that a car is in the lane I am changing into when there is no car present. This has happened several times, despite the camera showing no cars and checking for myself showed no cars. The first time it happened, it scared me so bad I jerked back into my lane and could have lost control of being safely in the lane. I filed a service request and was told it would cost me an est. $195.00 to have them look at it, but they said they think it is software related and tried to say they don't deal with software issues. It has experienced many occasions of decelerating for no cause when using the Full Self Driving, Autopilot and Cruise Control. It would cause me to have to disengage them as I felt it was effecting my distance efficiency. I found a new issue last night that caused concern. We have been getting high reports of following too closely, so I drove from Plainview, Tx to Amarillo, Tx in complete control myself while driving 100% perfectly and it reported that it claimed 63.5% of that drive was "Following To Closely" when in-fact any time a vehicle was in-front of me by (I think) 30 car lengths, I changed into the other lane where the was no vehicles in the lane at all. It is my personal opinion that it is a combination of the cameras not being infrared and not seeing well enough in low light situations, and the software unable to tell the difference between darkness/shadows and objects that should be avoided. These false alerts occur more for me in low light conditions, but the unneeded deceleration has occurred in all conditions.

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.

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.

Tesla vehicles do not have “Trailer Mode” available when aftermarket trailer options exist. Tesla only installs this required software when the towing hitch option is installed from the factory. When U-Hual or other services install aftermarket towing capabilities, Tesla does not add this necessary software package which is required for the safe operation of the vehicle when towing. This applies to the Model 3 and Model Y. The trailering mode software does the following: - Disables autopilot when trailering or towing. - Traffic aware cruise control increases the following distance for a safe stopping distance. - Side collision warnings are active which automatic steering interventions are disabled. - Collision Avoidance assistance is modified to accommodate the trailer and trailer weight. - EV Supercharger navigation only routes through “pull through” / “trailer capable” charging stalls. - Trailer sway mitigation. The vehicle’s stability control system maintains traction and stability and accommodates for the trailer sway/weight. (I may be missing some stuff but this is the most complete list I could find). Again, Tesla only adds this software to vehicles that get a hitch from the factory. If you have a U-Haul Hitch or other installed hitch on the Model 3 / Y, Tesla does not add this software. The easiest and most cost effective way to fix this would be to require Tesla to include the trailering mode software on all vehicles by default through a recall update.

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.

Tesla updated my vehicle last night, this morning with out any clear warning my cruise control activation actually activated the "full self driving" I did NOT realize this until my car turned the blinker on and tried to change lanes!!! I had no idea what it was doing! I took back control and tried to activate cruise control again but had self driving activate instead. So I just drove to work manually. When I got to work I looked up how to activate cruise control and realized that there is a setting to change how it is activated that I could change to get it back to "normal" for me. Then I was checking my email and Tesla had "Gifted" me a trial month of full self driving, they changed how my car functions without telling me and it literally started driving itself much to my surprise all as a PROMOTIONAL CAMPAIGN. Frankly I am pissed, this is unacceptable! They radically changed how my car behaves, what my controls actually do, without telling me, to make more money.

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)

Traveling on I35 South, approx 70 -75 MPH. Using adaptive cruise control/enhanced auto pilot. No vehicles present within a mile of my vehicle. Braking spontaneously engaged, reducing speed to 40MPH within seconds. If a vehicle were behind me they would have absolutely collided. I've not filed a report with Tesla. Vehicle did not display any warning, or any other sort of indication that a malfunction had occurred. The problem has not been reproduced by me, however an internet search returns multiple complaints of these exact symptoms.
