2021 TESLA MODEL Y Complaints

Multiple "phantom braking" events while using adaptive cruise control (no full self driving, just basic adaptive cruise). First time while going at interstate speed and crossing a bridge, vehicle saw a shadow on the road and slammed on the brakes thinking it was a vehicle. Obviously this is a startling and dangerous situation especially for vehicles behind you. This has also happened on the highway, flat terrain, roads were clear of any obstacles and it slams on the brakes thinking there is something in the road. Every time it does this, there appear to be shadows on the road (from street signs, light poles, trees, etc.). The sudden braking is of course bad, but there's also nothing in the vehicle that tells you why, no chime, it just hits the brakes. It still appears that cruise control is active, but it won't resume speed after an event like this until you turn cruise off and back on again. I know this isn't an isolated incident and it absolutely will cause a crash, if it hasn't already.

It seems like this is a common problem if you search "tesla phantom braking," which very obviously needs a solution. I commonly experience the phantom braking when there is a shadow like passing under a bridge. The car will slam on the brakes thinking the shadow is another car, which is obviously extremely dangerous especially on the highway. A simple solution would be to add a legacy cruise control option, while fixing the phantom braking. This would cause a lot less wrecks and deaths.

On February 20, 2023, my infotainment system console and screen completely failed as I was backing up to a Supercharger. This started with the typical lag I have filed service complaints for before, the camera occlusions, and then nearly caused an accident with the barrier pole in front of the Supercharger. This is the eighth near miss in over a year of ownership and the 27th occurrence of issues related to the infotainment system console and screen. Often, it is burning hot, other times it is woefully underpowered to accomplish anything in a timely manner (if at all) when these incidents occur. I have been to the Tesla service center twice about this very issue. Each time, I was told software update would be issued that would fix the problem(s). That has never been the case. With everything so reliant upon that center-mount display and its associated computer in this model of vehicle, it HAS to be considered a must-not-fail component to the extent humanly possible. I am taking this vehicle in for a third time for this and multiple other issues that seem to some degrees associated with the issue. After badgering the Tesla helpdesk personnel with demands to replace or fix the issue, they have told me on February 23, 2023 that they will be replacing the computer next week (whether this is to evaluate the device for issues or to hide evidence to their culpability in an incompetent design flaw, I cannot be sure).

The vehicle heating/defrost system is not functioning in cold weather. It only functions in my heated garage. In cold weather it cannot defrost causing visibility issues, driver distraction (trying to get the heat/defrost to work while driving) and a reduction in blood flow to the extremities. The heating system blows freezing cold air into the cabin when on. I have written a lemon law letter to Tesla, demanding the vehicle be replaced under Alaska law, and they have not done so after 80+ days. The vehicle’s supermanifold was damaged the day we took delivery. Tesla has not honored Alaska law and I’ll be filing paperwork with the state’s attorney general’s office. Tesla should not be allowed to operate in the State of Alaska due to committing an unfair trade act in the State of Alaska and endangering the lives of their customers.

On today’s day 2/24/23 approximately 13:18 hours. While I driving my 2021 Tesla Model Y ,the rear suspension failed. The steering wheel is not responding and I was unable to turn it or control it. This resulted in the rear tire and rim pointing to the left. This caused the tire to become unseated on the rim. The metal rim hitting the pavement and the angle of the Rim/wheel make me lose control of the vehicle and cross 4 lanes of traffic in a few seconds until I could get the car stopped. There was no prior noise or notice. It was raining lightly. I purchased the Tesla due to its reliability and all the safety features. As I know Tesla had been described as a high safety level with full automation engaged vehicle. However, I feel there is an issue with the suspension manufacturing defects of Tesla model Y which did not activate or warned me to avoid a simple collision. There was also no automatic breaking which occurred to avoid the collision. Luckily, there were no injuries on my accident. In fact, what if the driver had severe injuries, unconsciousness or even fatal during the impact of accident ? What if I was on autopilot? I am very concerned about the fact of Tesla manufacturing system. The dealership said this is common and caused by the rain which is an entirely dumb statement as I'm sure teslas are designed to be driving in all types of weather. I have seen numerous recalls and issues with the rear suspension and I am asking Tesla to take ownership of this issue and fix the problem. I look forward to your response on next steps to remedy this situation and repair my tesla. Thank you

On February 19, 2023, I was driving my 2021 Tesla Model Y on I-5 from LA to Sacramento on a clear afternoon. I was using adaptive cruise control (ACC) set at 78 mph, but not using auto-pilot, in the fast lane with a car following me. My car suddenly braked aggressively without anything in the roadway ahead of me. I then applied the foot brake and veered off onto the gravel left shoulder to avoid having the car behind me hit me. I saw in the rear-view mirror the following car swerve to the right to get around me, entering the slow lane. I believe that when I stepped on the brake, the ACC turned off and the car's automatic braking ceased. I then got back into the fast lane as there were no other cars approaching and resumed my drive. I didn't notice the speed my car had decreased to during the incident before I resumed speed, but I guess it may have been about 40 mph. Phantom braking happened one other time on I-5 on my way to LA from Sacramento two days previously (Feb. 17) also while in ACC, but there were no other cars around me and the automatic braking stopped when I tapped the brakes and I resumed my speed. In the year and a half we have owned the car, we have experienced approximately 10 instances of phantom braking, but fortunately, no accidents.

I have been driving long distance 418 miles today from Phoenix, AZ through Las Vegas, NV and north. In my 6 hour journey today my breaks were applied randomly by the computer around 20 or more times on autopilot and on cruise control. It is an extreme safety hazard. I want this on record because this is day one of a cross country trip and in case anything happens. The phantom breaking was so frequent in the last hour I could not drive with autopilot on anymore for fear of a car following me would crash into me at highway speeds above 65mph.

I was in 2 accidents with this car within a span of less than a year all with the same problem. I had not been in any accident over 40 plus years until this car. First incident was at a drive through when creeping up to the next window the car took off hyperaccelerating. I was able to avoid the truck in front of me from back ending her however scraped her tailpipe causing extensive damage to my car. She then hit the car in front of her. Second incident was approaching my home in my 20-30 mph neighborhood and went to go from 20-30 when car accelerated at a fast speed and was unable to control it being it happened so fast. Hit a tree. All the airbags went off. I could have been seriously injured as anyone who had been on bikes or walking .

The contact's client owns a 2021 Tesla Model Y. The contact stated while they were driving approximately 50-55 mph with the vehicle in self-drive mode, the vehicle veered to the left and crashed into a guard rail. There were no warning indicator lights illuminated. There were no reported injuries, air bag deployment, or fire. A police report was filed. The vehicle was towed to an unknown location. The contact called the local dealer but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was unknown.

Numerous times we have experienced phantom braking when the cruise control is engaged at highway speeds. We think it occurs when you are close to cresting a hill and a vehicle is detected in the distance. The vehicle is quite distant, perhaps 500-1000 ft, but the auto braking system only see a short distance of lane lines (because they are out of sight on the other side of the crest) and interprets the vehicle to be much closer. This generally occurs about once every 100 miles of highway driving. Because of this, we are reluctant to use the cruise control. The date provided below is just the latest occurrence.
