2018 TESLA MODEL X Forward Collision Avoidance Adaptive Cruise Control Problems

Tesla X in full self driving mode failed to lower speed and detect stopped in-lane vehicle on a very sharp turn, crashing into the back of the vehicle at significant speed.

Our Tesla Model X is failing recently with several issues as listed below: 1. 'Autiopilot disabled' - Autopilot was not available to use since 09/2024 after upgraded to 12.x FSD upgrade. Tesla service diagnosed in 11/2024 with some error connected to evaporator fan, advised me to replace the kit at an estimated $580 2. 'Unable to start' - HV battery failed on 03/06/2025 with series of failures that was reported to NHTSA (VOQ#11651899). Tesla replaced the battery, and service delivered vehicle on 03/24/2025 3. 'Hood unlatch' failure - while driving home from Service center on the same day at 70 mph on I-95 freeway, the 'hood' popped up blocking the front view, and had to pull vehicle to shoulder to safety. There was NO warning message on the screen at all. Took the vehicle to service immediately, and service team pointed that they forgot to turn on 'auto-latch' resulting hood...

‘safety restraint system issue’ error pops up when ever car is turned on was told that can cause airbag to not be deployed when needed.

While driving on highway with autopilot on . I received the message "Steering Assist reduced .Vehicle will require additional force to steer". I believe I hit a rough patch on the highway and my steering lost power and became very hard to steer the vehicle. Somehow I managed to drive for 20 miles to safety. When I recached home I did power reset few times and the issue went away. I noticed similar issues with model x but not for year 2018 Model x. I have opened a service request with Tesla .Tesla send me an invoice of $5500 for repair.

The Tesla recall under NHTSA Recall No: 23V-838 has not been completed by Tesla. The upgraded computer I purchased from Tesla and had installed in December 2021 cannot accept the OTA update. Tesla is requesting that I replace the computer again for 2 thousand dollars for the recall OTA. Telsa said my current computer has an internal bug and needs to be replaced. I should not have to spend 2K for another computer that barely lasted 2 years.

Auto pilot

The Full Self Driving System failed to operate correctly. This caused my car to hit another car. I have asked Tesla for the data they use to tell what the driver was doing when the system was on but the Tesla staff who respond to my requests plead ignorance of what data I am referring to. I am not ready to spend the money it would cost to hire a lawyer to force Tesla to hand over the data from their system. I have video from the Tesla camera showing what happens. I will try to upload it. Here is a quick run through of what happened: I entered the freeway and got into the left lane. Once I was safely in the left lane and up to speed I turned on the FSD keeping my hands on the steering wheel. After a few moments the car veered to the...

I was driving on the highway on Tesla enhanced auto pilot when traffic came to a stop I’d notice my Tesla model X was not about to stop nor slow down for the stopped traffic so at the last minute I had to slam on my brakes and swerved to the right lane where I was hit by a truck pulling a trailer which subsequently rammed me into the truck I was trying to avoid rear ending after Teslas forward collision warning failed to notify me or stop the car from crashing in the first place

On a recent 2000 mile trip, we experienced several (10-20) incidents of unnecessary, very strong braking. There were no apparent reasons for the very strong braking episodes. In some instances, there were no cars in front of us and no cars behind us for many miles (I-40, New Mexico). Braking was so severe that it likely would have caused a collision if cars had been closely following us. We have traveled this route several times in past years with no similar emergency braking incidents.

After I started an update as requested on Tesla app, the car was giving error messages. I was able to drive but the errors were - 1. reduced steering assist 2. Autopilot and cruise control not available

About 224 miles N. of Los Angeles, on I-5, Southbound, the car aggressively braked while using traffic aware cruise control. Speed was around 75 when braking started. Speed dropped to 55 MPH at the end. There was a couple additional brakes on this southbound journey. I can't believe that Tesla thinks they can implement full self driving when they can't manage to maintain a constant and not jarring speed. This is a recipe for disaster.

https://youtu.be/yRdzIs4FJJg "Autopilot is set to shut down 1 second before any impact. Makes the driver 100% in control before an accident. Makes the driver 100% responsible. Tesla has killed two motorcyclists in the past 4 months. At night the ai can't tell the difference between a motorcyclist up close and a car far away. So, it assumes car and runs right into it. Another interesting issue with teslas autopilot. They claim its 10x safer than a person. That not true. The claim is based on sheer accidents per mile. Autopilot is only really used on the highway, eating up miles quickly and in an environment where, although consequences of crashes can be more severe, they happen less often. When adjusted to compare highway driving autopilot to highway driving people, it's really only about as safe as a person, if that. In their 2022 cars tesla has done away with radar....

While on cruise control (autopilot) on the highway, the vehicle occasionally violently slows down. The majority of the time, this happens near or just before an exit/entrance ramp and if the car is in the rightmost lane. It happens regardless of traffic conditions and even if there are zero cars around, it will still "hiccup" and hit the brakes. I've noticed that the cruise control system sometimes automatically changes the maximum speed for the cruise control to 35-45 MPH which explains the sudden braking. It is semi-replicable by setting the cruise control to a comfortable highway speed (say 65 MPH) while the car is in the rightmost lane, then driving past a (normally) heavily trafficked entry/exit merging area. If requested, I can probably find a safe time and area to replicate this and send in my dashcam footage of the incident.

On May 15. 2022 at 4:25PM while traveling north on highway 395 about 14 miles south of Bishop Californa. While traveling with little to no traffic, using adaptive cruise control (NOT SELF DRIVING) the vehicle suddenly stopped for no apparent reason in the middle of the highway. Fortunately, there were no cars behind us otherwise I probably would not be writing this. I have registered a similar complaint back in March for the same issue. We have had a total of 4 “phantom braking” incidents since buying the car in October 2021

Our Tesla has had the “phantom braking” on 3 occasions. The first incident happened on southbound interstate 5 near firebaugh. right after we purchased the car. The car suddenly stopped from 70 MPH to about 25 MPH in the middle of the freeway. The second event on northbound 395 at 2:45pm 3/20/2022The car went from about 60 mph to about 25 with out warning. It happened once again at about 4:03PM the same day. All of these events occurred while the car was in adaptaive cruise control, it in self driving mode. I have one event on video, that showed skid marks ahead at the same time the braking occurred.

While driving at speed approximately 4:20PM EST April 9th, 2022 on I95 near the Georgia/South Carolina border the onboard computer froze and became unresponsive, including the speedometer, the radio, navigation system, etc.. I became aware of the issue because the car started to slowly slow down but the display continued to show 70 MPH. I forced the computer out of Autopilot but the car continued to show it was in autopilot. shortly after the display behind the steering wheel went blank then rebooted, followed by the center console. thankfully I was paying attention and did not panic, had I panicked I could very easily been in an accident as I did not know what was going on with the car. I reached out to tesla multiple times following the incident and the agents and agents were non-caring and treated it as no big deal, and acted as if I should...

Constantly phantom breaks. 30+ times on cruise control (not autopilot) in a 6 mile stretch. Started October 2021, occurs daily on two lane roads

Since I’ve owned this car in Jan, 2018, the auto driving system seems to think there are obstacles and auto brakes abruptly for no reason. In addition, the car fails to break sometimes when there are cars directly in front of the car.

TOUCH SCREEN AND MAIN DISPLAY UNIT AND CONTROLLER PROBLEMS. IT GOES BLACK VERY OFTEN, IT BECOMES SLOW MANY TIMES, RESTART TAKES A LONG TIME, SOMETIMES BLUETOOTH STOP WORKING FOR ALL DEVICES, NO SOUNDS CHIMES, NO AUDIO SOMETIMES, THE BLANK SCREEN STAYS FOR LONG TIME SOMETIMES DURING THE DRIVE. THIS IS BIG SAFETY CONCERN. I WENT TO SERVICE FEW TIMES AND MOST RECENTLY TODAY AND TESLA SERVICE DENIED THE SERVICE OR FIX SITING EVERYTHING WORKS. THEY ASKED ME TO RESTART THE SCREEN. THEY TOLD IF SCREEN GOES BLANK WEEKLY IT'S ACCEPTABLE.
