2026 Tesla Model S problems

“Speed profiles don't adhere to actual speed limits. Speed can be higher or lower than posted. I can be driving in a 55mph speed zone and it will drop to 35 then accelerate to 65. On roads that have no speed limit posted car tends to want to go 55 rather than a more sensible speed of under 30, especially at night on a dirt road with wildlife about. Car will also see access road speed signs and slow down in the middle of traffic. To me i don't feel safe and have to disengage the system which adds stress to the drive. Being able to set my own speed is the solution, not having the car set it.”

“Supervised FSD does not have a remedy if it assigns an incorrect speed limit to the current roadway. The only action available is to disengage FSD. This incorrect speed limit happens quite often, especially in construction zones with temporary speed limit changes. Tesla used to have a ‘max speed’ setting that the driver could use to override an incorrect speed limit, but they removed that capability.”

“COMPONENT: The rear window glass has optical distortion in the zone viewed through the interior rearview mirror. Vehicles behind me visibly warp and change apparent size as they move across the affected area of the glass. The vehicle and component are available for inspection upon request. SAFETY RISK: The distortion impairs my ability to accurately judge the position, size, distance, and closing speed of following vehicles. A smaller vehicle, such as a motorcycle, could be misjudged or lost in the distorted zone during a lane change, creating a collision risk. The condition is present at all times while driving. REPRODUCED/CONFIRMED: Yes. Tesla Service (365 Caldwell Dr, Springfield, MA) confirmed during my service visit that the same distortion exists on multiple other newer Model S vehicles, characterizing it as a normal aesthetic of the rear glass. Tesla stated in writing on [XXX] that "mild distortion is still to be expected with curved glass." Tesla replaced the rear glass; the replacement exhibits the same distortion, slightly worse. At vehicle pickup on [XXX], the Tesla Service Manager verbally acknowledged the issue was not resolved and stated all such…”

“Subject: Safety Concern—Model S Plaid Rear Tire Wear I am submitting a formal complaint regarding severe premature wear on the inside edges of both rear tires on my Model S Plaid\. I have owned the vehicle since XXX, and it has only 11,980 miles\. Both tires appear to have exposed cords along the inside edges, while tread remains elsewhere\. I have attached a photo\. Approximately 99% of my driving is with FSD engaged\. This uneven wear raises serious safety concerns and may indicate an alignment or suspension issue\. I was advised not to use Low suspension mode or “Mad Max” mode\. Please clarify which settings this refers to, explain the technical basis, and identify where this restriction appears in Tesla’s operating instructions\. I expect to use the vehicle’s factory features as instructed without severe tire damage or increased risk of failure\. I was also told that some owners have installed aftermarket adjustable camber arms to address similar wear\. The attached photo shows N2itive SX\-P2 arms advertised at $995, excluding installation and alignment\. I am concerned about having to purchase aftermarket parts to correct this condition\. Please: - Inspect…”
