2018 Tesla Model 3 lane departure problems

“Following Tesla's over-the-air deployment of FSD 14.1 Lite, the HW3 Autopilot computer in my 2018 Tesla Model 3 failed. FSD / Autopilot worked normally before the update and stopped working immediately afterward. Tesla Service diagnosed the vehicle XXX and verified the alerts APP_W207, APP_W462, APS_W182, APS_W188 and APS_W185. The technician attempted hard and soft resets and a firmware reinstall, and verified power and ground to the car computer. All attempts failed. The technician's notes state the secondary autopilot processor is no longer communicating and "a new car computer is needed." The failure has disabled Automatic Emergency Braking, Forward Collision Warning and Lane Departure Warning, as well as FSD / Autopilot. Tesla denied a goodwill replacement in writing on XXX, stating there was no evidence linking the failure to a software update, after the technician confirmed the computer had failed. Tesla provided a written estimate for the replacement of $2,616.37 total (invoice dated XXX). I have not authorized the repair. Tesla also confirmed in writing that my vehicle is not currently eligible for the HW4 upgrade. I sent a formal Notice of Dispute to…”

“When using FSD in "chill" mode the car attempted to cross over into oncoming lane on a two lane highway. There were no oncoming cars and I overrode the car almost immediately. The car has not been inspected by anybody. No warning light, messages or other symptoms. I have a video of the incident for a Viofo dashcam installed in the car.”

“No warning messages at all, all cameras/sensors stopped working all at once while driving, full self drive stopped working, lane assist, safety features of full self drive was degraded by this. Car software v12 (2024.44.25.2 288ce84bb43e), according to the dealership the computer fried randomly.”

“Front suspension creaking & rattling going over bumps Tesla took days & days & never called me w/ problem I kept calling in!! Finally decide it is a KNOWN recall problem w/ Suspension bolts & sub frame! They told me they torqued them & would test drive for noise & I never heard from them! I had to call in. Suddenly I had a $4200 estimate for repairs including $322 1.24 hours of diagnosis??? A known problem other 2018 Tesla’s have been recalled for ??? Very suspicious?? How do I know they didn’t torque it too far & strip bolt themselves??”

“October 12, 2024. I was using the Tesla on autopilot. I was in the far right lane and the freeway was curving to the left. The car was following in the lanes, but then all of a sudden it stopped following the freeway and drove into the right guardrail. There were no alerts by the car. It did not warn to take over the vehicle or attempt to avoid the collision. The car drove directly into the guardrail without warning and was totalled.”

“I have a 2018 Tesla Model 3 that was involved in an accident on 10/12/2024. It has Enhanced Autopilot, which was the most advanced version of self driving when I bought the car. It was engaged in "Navigate on Autopilot" on the freeway. The car was following the freeway as it veered to the left, but then it stopped following the lines and crashed into the side of the freeway. The result of the accident was a total loss on the vehicle. I had shoulder and neck pain that have not required serious medical attention, but it was almost a week of discomfort and difficulty sleeping. My insurance company has deemed the vehicle a total loss and I will have to get a replacement. There were no warning alerts and the vehicle did not recognize that it was leaving the freeway lines. I was not going over the speed limit. The car did not prompt me to take over the vehicle because of danger. It just went straight towards the freeway guardrail. The car is not drivable due to the damage it sustained.”
