2018 Tesla Model S Speed Control & Cruise Problems

While driving using cruise control, in the space of 9-10 miles, the vehicle had 14-16 instances of sudden, unexpected braking for no reason. Most were moderate braking incidents slowing the car 15-30 mph before I hit the accelerator to get the car back up to speed. 2 incidents were where the car slowed 5-10 mph then resumed speed. Very disconcerting. There was little to no traffic on the road and in every case, there was no other car within a 1/2 mile or more to the front. Finally got fed up with this and turned off cruise. Left cruise control off as I passed through a city then decided to try it again. Soon after engaging cruise at 72 mph, the car suddenly and violently braked for no reason. It was such a hard braking that one of my dogs in the back seat crashed into the front seat. The hard braking continued until the speed was about 20 mph at which point, I hit the accelerator in order to resume speed. Note that no other car was visible on the roadway which was a 4 lane highway. Conditions were clear and dry. Soon after this incident, while still on cruise, the car suddenly braked moderately hard. Since the road was clear before and behind me, I decided to see what would happen. The car slowed to 38 mph and stayed at that speed for 3-4 seconds then slowly resumed the set speed. A short time later 1-2 miles further, the exact same sequence happened again. Again, note the road was clear with zero traffic ahead of or behind me. I then turned off cruise and decided to drive manually the rest of the way. This car is dangerous and should be removed from the road

On freeway in traffic, autopilot is enabled. Vehicle is running perfectly fine in start stop traffic slowing down and speeding up as needed. Traffic starts to clear up, and as vehicle speeds up, there is a sudden slowdown again. Instead of braking/slowing down, autopilot turns off without an additional audible alarm (just the standard sound for turning off autopilot), instead the forward collision warning alert goes off. Able to brake in time to prevent accident.

While driving out 2018 Model S, it will brake hard while in adaptive cruise control of full self-driving mode for no reason. This happens frequently, whether driving on the highway or on city roads. It is terribly unsafe. I'm afraid eventually someone following too close will hit me.

Driving down an interstate at the speed limit, with light traffic. No cars immediately or in ahead of me. The car put on the brakes, or what is commonly referred to as "phantom braking" as I understand it. It has done this on prior occasions and I am familiar with it. It generally seems to be triggered by inconsistent pavement coloring or shadows. The car rapidly braked until I took over (I was using "Navigate on Autopilot" which was managing the speed and lane-keeping). There were no injuries or dangerous situation created during this event, besides being quite abrupt and startling. There are no known failures or issues in my vehicle that would have been likely to contribute. This occurred on Nov 24 in the late afternoon, driving westward. Weather was overcast.

Apparent software issue with Adaptive Cruise Control causing unexpected hard braking at highway speeds. Random hard braking occurs on open road when road is clear, flat, and no other vehicles nearby. Narrowly avoided being 'rear-ended' during several occurrences by car behind. I drove the car this week on a two day road trip from Palm Springs to Santa Fe and this issue must have occurred 18-20 times during the 750 mile trip. I also tried using difference settings and nothing seemed to eliminate the issue.

The contact owns a 2018 Tesla Model S. The contact stated while pulling into a parking space, the vehicle accelerated at high speeds without any warning, causing the vehicle to run through a construction site and collide with a building. The air bags were deployed, and the passenger in the vehicle was injured and sought medical attention. The contact was unsure if a police report was filed. The vehicle was towed. The manufacturer was not contacted. The failure mileage was unknown.

The contact owns a 2018 Tesla Model S. The contact stated that while driving down an inclined driveway the vehicle suddenly experienced unintended acceleration causing the driver to lose control of the steering and crash into the nearby RV garage. During the incident, the airbag was deployed and the driver sustained injuries to both knees and left hand. No police report was taken. The cause of the failure was not determined. The contact indicated that the failure had previously occurred in 2018. The manufacturer and local dealer were not notified of the incident. The failure mileage was 38,000.

Driving on a freeway at 75mph with autopilot turned on, the car suddenly braked, requiring manual intervention to accelerate to intended speed. After this the car continued as normal. There was no visible obstruction. Fortunately I have had this happen while a vehicle has not been behind me otherwise there is a possiblity of a crash.

WHILE DRIVING ON THE EXPRESSWAY, CRUISE CONTROL WAS ENGAGED AT 65-70 MPH FOR 3-5 MINUTES, UNTIL SUDDENLY, THE CAR SLOWED DOWN ALL BY ITSELF TO AROUND 50MPH WITH VIBRATION AND JERKING. THE BRAKE WAS NOT DEPRESSED AT ALL. NO OTHER CARS WERE IN FRONT OF ME OR AROUND ME AT THE TIME OF INCIDENT

THE CAR SOFTWARE HAS BEEN MODIFIED AND APPEARS TO BE COMPROMISED. SETTINGS RELATED TO SAFETY AND AUTOPILOT HAVE BEEN UNSTABLE. DRIVER PROFILE DOES NOT WORK PROPERLY. FACTORY RESET PERFORMED BY TESLA PARAMUS AND BY SWITCHING EMAIL ACCOUNT DOESN'T NOT REMOVE THE MALWARE. PERSONAL DATA AND MALFUNCTIONING OF THE CAR CONTINUE DESPITE SEVERAL COMPLAINTS TO TESLA.

AS I WAS PARKING THE CAR, THE CAR SUDDENLY ACCELERATED WITHOUT WARNING, WENT OVER THE CURB AND HIT A TREE AT HIGH SPEED. THE AIR BAGS DEPLOYED DURING THE CRASH AND THE FRONT OF THE CAR WAS BADLY DAMAGED. I SMELT SMOKE IN THE CAR AFTER THE ACCIDENT. WE GOT OFF THE CAR IMMEDIATELY AFRAID OF THE BATTERY GOING INTO FLAMES. THE CAR HAD TO BE TOWED AWAY. THIS WAS SUCH AN UNUSUAL EVENT AND A FREAKY ACCIDENT AS THE CAR ACCELERATED AS I WAS PARKING IT. THE CAR CAME TO A STOP BEFORE IT ACCELERATED AT HIGH SPEED AND I LOST CONTROL OF THE CAR. IT MUST BE AN ERROR IN THE CAR'S TECHNOLOGY.

I WAS PULLING INTO A PARKING SPOT IN A PLACE I PARK ON MANY OCCASIONS, HAD MY FOOT OFF THE ACCELERATOR, TO PUT ON THE BRAKE, AND THE CAR SUDDENLY ACCELERATED, WENT UP OVER THE CURB, AND ALMOST DOWN AN EMBANKMENT. I WAS ABLE TO STOP THE CAR BEFORE THAT HAPPENED.

TL* THE CONTACT OWNS A 2018 TESLA MODEL S. THE CONTACT STATED WHILE SHIFTING INTO PARK, THE VEHICLE SUDDENLY ACCELERATED FORWARD AND IMPACTED INTO THE WALL OF A BUILDING. THE FRONT OF THE VEHICLE WAS DAMAGED AS WELL AS THE BUILDING CAUSING ITS ELECTRIC TO SHUT OFF. NO WARNING LIGHT WAS ILLUMINATED. THE CONTACT WAS ASKED ABOUT THE AIR BAG DEPLOYMENT AND CONFIRMED THAT THE AIR BAGS DID NOT DEPLOY. THE CONTACT DID NOT SUSTAINED ANY INJURIES OR SEEK MEDICAL ATTENTION. IT WAS UNKNOWN IF A POLICE REPORT WAS FILED. THE VEHICLE WAS DRIVABLE AFTER THE IMPACT.

THE FAILURE MILEAGE WAS 12,000.

THE CAR UNINTENDED ACCELERATED WHEN I PULLED INTO GARAGE AND WAIT FOR GARAGE DOOR OPEN. THE SUDDEN ACCELERATION IS TOTALLY OUT OF CONTROL, EVEN MY FOOT FIRMLY STEP ON THE BREAK PEDAL. THE ACCELERATED CAR WENT THROUGH THE GARAGE DOOR TOWARDS RIGHT, AND HIT AND LIFT THE OTHER PARKED SUV INSIDE THE GARAGE. THE SPEED AND FORCE PUSH THE SUV TOWARDS THE BACK OF GARAGE WALL, AND TOTALLY DAMAGED THE PART OF MY GARAGE.

I WAS AT A PARKING LOT AND I WAS MAKING MY WAY INTO A SLOT WHEN I FIRST HAD TO REVERSE THEM WHEN I CHANGED THE GEAR THE DRIVE AND RELEASED THE BREAKS TO MOVE FORWARD INTO THE SLOT I SUDDENLY ACCELERATED AND HAD TO PRESS ON THE BREAKS HARDER THAN EVER BECAUSE I THOUGHT AT FIRST I WAS RELEASING IT TOO FAST. BUT EVENTUALLY I SCREECHED INTO A FULL STOP AND AVOIDED HITTING THE CARS PARKED AND WORSE GOING OVER THE STREET ONTO INCOMING TRAFFIC. I NOTICED TIRE MARKS THAT MY BREAKING HAD MADE AT THE LOT.
