2023 TESLA MODEL Y Complaints

I was driving a Tesla Model Y with Full Self-Driving (FSD) engaged in Standard mode on a wet roadway post-rain. Shortly before the incident, my vehicle had completed a lane change on FSD and was traveling with traffic flow. A vehicle ahead braked suddenly after reacting to another vehicle merging unsafely near a lane split. The stopping occurred quickly, reducing available reaction time. The FSD system did not appear to respond with sufficient braking force or early enough given the conditions. A forward collision warning sounded shortly before impact, but there was limited time to avoid the collision. The vehicle ultimately rear-ended the car ahead. I am submitting this report because of the system’s delayed response in wet conditions, failure to ensure enough space on FSD- especially after a lane change and during a sudden/abrupt traffic slowdown may present a safety concern if experienced by other drivers.

On April 16, 2026 around 7:30pm CT, I was driving a Tesla Model Y 2023 on I-35 near downtown Austin. There was an extreme traffic jam, I turned on the Auto Pilot so it can cruise by itself without touching anything. It worked for a while, but suddenly it veered off to a lane on my right side, crashing into a large truck on the front right. This damaged all the front and passenger side fender. The car had to be towed. I used this feature many times in the past, it always stayed within the lane. This time it acted erroneously. This should not be marketed as "auto pilot" that people may lose their lives due to insufficient safety guard in the system. Fortunately the traffic was moving very slowly, no one was hurt in my case. I got all incident data downloaded from Tesla to prove its fault. Based on the data, the Autopilot system had a fault starting at 12:50pm and 14:55pm, and was disabled at 15:59pm, but there were no warning as I turned it on when I drove on I-35 around 7pm. See the attached data file (highlighted rows, the claim system doesn't allow the original Excel file to be uploaded).

I was driving home with Tesla FSD engaged, and my right turn was approaching. Since the Tesla did not activate the right turn signal on its own, I turned on right indicator manually while FSD was still engaged. But FSD changed the lane to the left and accelerated, and rear-ended the vehicle in front of me.

Hello, I am reporting a safety issue with the Full Self-Driving (FSD) system on my 2023 Tesla Model Y. The vehicle has been taken in for service four separate times for this issue. During these visits, Tesla service technicians were able to reproduce and confirm the problem. I have been explicitly advised in writing by Tesla service not to use the Full Self-Driving system due to safety concerns and to use standard AutoSteer instead. While FSD is engaged, the vehicle exhibits dangerous and unpredictable behavior, including: Crossing over double yellow lines into opposing traffic, Driving significantly below the speed limit (e.g., ~4 mph in a 25 mph zone), Stopping in the roadway without any traffic or obstructions, Swerving within the lane while attempting to maintain position, Hesitation during turns, stop signs and at intersections. Tesla has attempted multiple repairs, including replacing steering-related components and multiple cameras across separate service visits. These repairs did not resolve the issue. At my last service visit Tesla has since indicated that the problem is likely software or firmware-related and that there is currently no available fix, with a recommendation to wait for a future update of an unknown timeline. If their statement is correct, this issue should be affecting every vehicle out there on the same software. At this time, I have been advised not to use a system that controls steering, braking, and acceleration due to safety concerns, and no timeline or resolution has been provided. I am submitting this complaint because the system behavior presents a potential safety risk to myself, passengers, and other drivers, and the manufacturer has not provided a current fix despite multiple confirmed service visits. I am attaching my last service invoice only in regards to this matter where they indicated to not use FSD, but I can provide other documentation showing the replacement of cameras and steering parts as well as videos if needed.

The rear subframe wiring harness on my Tesla contains a significant design flaw that creates an unreasonable safety risk. The factory-installed corrugated protective tubing (wire loom) terminates prematurely, leaving approximately 1 inch of critical wiring completely exposed at the connector. This specific harness uses soy-based insulation, which is a known attractant to rodents. Because of the 1-inch gap in protection, rodents have been able to sever the same connector twice within a 30-day period Safety Risk: The exposed wires in the rear subframe harness are responsible for Rear Drive Unit communication / Wheel Speed Sensors / Brakes]. A failure of these wires while the vehicle is in motion could result in a sudden loss of propulsion, unexpected braking, or the loss of stability control systems. This creates a high risk of a collision, particularly at highway speeds.

Excessive inside tire wear even tough tires are not at tread wear indicator cause dangerous situation. Tesla knows of this problem. And it is designed this way with no camber adjustment to rear suspension

Parked into driveway. Placed car into park. In doing so, car suddenly rapidly accelerated into reverse until I slammed on the breaks. My son was behind the car grabbing something out of the trunk at the time. I could have ran him over if I wasn’t there to slam on the breaks!!! Car was NOT placed into reverse and accelerator was NOT pushed.

The FSD has been failing more often. Yesterday we took a one00 mile trip and the car twice tried to veer into the side cement barrier, more times than I can count. It breaks hard while we were driving over 55 miles an hour. And two times it weirded left over the double line into oncoming traffic lane.

The forward-facing camera system, Automatic Emergency Braking (AEB), and Autopilot/cruise control have repeatedly failed on a 2023 Tesla Model Y with approximately 22,000 miles. The AEB system becomes unavailable and the Autopilot disengages without warning, including at highway speeds of 70 mph and city speeds of 30 mph. The active safety systems are functional less than 10% of the time. The sudden, unexpected loss of active safety systems at speed presents a serious risk of accident and injury. The problem has been reproduced and confirmed by an authorized Tesla service center on three separate occasions. Repairs attempted include replacement of the triple forward-facing camera assembly (twice) and replacement of the car computer (HW3) with a firmware update. Despite these repairs, the defect recurred within days of each service visit. A fourth service appointment is now scheduled for the same issue. Warning alerts appeared on the vehicle display prior to each failure, specifically "Camera Blocked" and "Automatic Emergency Braking Unavailable." These alerts were first detected in August 2025 and have recurred through January 2026. All three repair attempts were covered under the manufacturer's Basic Vehicle Limited Warranty, confirming acknowledgment of a manufacturing defect. The vehicle and components have been inspected by the manufacturer's authorized service technicians. The vehicle is available for inspection upon request.

This is about my tires, follow-up from my previous report ID 11726883 regarding inadequate original tires. Since 1. Tesla was unresponsive to my defective tire issue, 2. Discount Tire insisted on my continuing to drive until all 4 tires reached 4/32" tread depth, and 3. My local tire store, where my Tesla would get towed in the event of a flat while I'm near my home town (since the nearest Tesla dealer is >50 miles away), is unable to access the warranty on the original Continental Contact RX tires. He was originally told that they had to be worn to 2/32", I was advised to call Continental Tires Customer Service and chose the option of Warranty claims. I was immediately advised that Continental does not warranty original equipment tires. I was therefore forced to spend significant extra money at my local tire store, which does not get the volume discounts that Discount Tire gets. It is no longer practical for me to use Discount Tire, an hour's drive down the interstate, for my tire needs. It is further impractical for me to drive on tires that do not provide the safety that I need, despite the fact that Discount Tire would give a credit of approximately $50/tire once all 4 reached 4/32". I also now realize that Discount Tire is providing that credit at their own cost, despite the fact that they told me that the Continental with the TE on it (mine has a T2) is eligible for warranty rebate. They scanned my tires with the hand-held scanner and their computer indicated it was rebate-eligible, though the Warranty was for 40,000 miles instead of the 55,000 that the first Discount Tire person told me on the phone. I bought new tires yesterday at 33,002 miles. Bottom line is that both Tesla and Discount Tire are protecting Continental Tires from the unsafe original tires for (at least) the Tesla 2023 Long-range Y. None of the 3 are responsible to the at-risk public who is paying for their profits.
