2021 TESLA MODEL Y Complaints

My 2021 Tesla Model Y experienced a sudden loss of steering assist, resulting in an extremely heavy steering and loss of steering ability, at highway speed. I needed extreme efforts to push the steering wheel to go off highway to avoid accident. This happened on 6/14/2025 around 3PM. Tesla service diagnosed "internal electrical/mechanical steering rack failure", but no recall was issued for my VIN. I've reviewed NHTSA Recall SB-25-00-004 (2025) for 2023 Model Y involving EPAS/steering assist failure. The symptoms in my car appear identical. I believe the issue may affect more model years than the recall currently covers and request HNTSA investigate further.

The bolts connecting the front upper control arm and steering knuckle may not have been tightened properly, potentially leading to detachment.  This causes the car to have squeaky, leaking noises when going over bumps and making turns.

I WAS DRIVING ON AN INTESTATE HWY I-70 EAST BOUND ON THE LEFT LANE AND I WAS ABOUT TO TAKE THE EXIST 62. I WAS ON CRUISE CONTROL AND IT WAS RAINING AND THE ROAD WAS WET. WHEN I TRIED TO CHANGE THE LANE THE CAR AUTO BRAKED AND CAR SKID AND ROTATED 360 DEGREES AND HIT THE RAILING. THE CAR GOT DAMAGED FRONT AND BACK. LUCKILY THERE WAS NO VEHICLE NEAR US SO MY FAMILY WAS SAFE. BUT I DONT KNOW WHY THE CAR AUTO BRAKED AND ONE SHOULD NOT HARD BRAKE WHEN THE ROAD IS WET. I CALLED 911 AND TESLA INSURANCE. I TOOK THE CAR TO THE BODY SHOP AND THEY ARE DEEMING IT TOTAL LOSS. PLEASE TAKE NECESSARY ACTIONS SO IT DOESNOT HAPPEN AGAIN

“Front passenger Safety restraint system fault, service required” RCM2_a636 message keeps appearing on the screen. It happened right after I bought the car, so I took it to Tesla to fix. It went away for a few months and now it’s back again. According to Tesla, this fault, “ Based on the airbag system's self-diagnostic checks, a persistent fault has been detected in one or more safety restraint components. This could involve seat belts, impact sensors, occupant sensors, or related safety components. • If the airbag warning indicator stays on, the vehicle should not be driven until inspected. • Recurring faults require immediate Tesla service attention. • Pre-tensioner or sensor damage can compromise proper seat belt functionality.” This is a serious safety issue that should be addressed in a recall as it could jeopardize occupant safety of the seat belts or air bags do not work. It also appears to be somewhat widespread and persistent. Tesla also does not appear to have a permanent fix as the first time I took it in they made a comment about one repair already having been done on this before I got the car as a certified used one from Tesla.

I was driving slowly at a parking lot of a supermarket and preparing to park on my right. When I saw a car on my left front backing up, I pressed on the brake pedal immediately and turned the wheel slightly to the right. All of a sudden, the Tesla accelerated on its own with a very strong force and high speed, with the wheel turned sharply on its own toward the right. The Tesla then run through the steel fence of the parking lot, flying past the sidewalk, and finally settled on top of a big rock on the ground (which is placed there to protect the supermarket building). All of these happened so fast with such a strong force and all in an unintended manner. I was not injured and luckily no other persons or vehicles were involved. However, the vehicle was totalled and there were damage of the supermarket property.

Upper and lower control arms failed, and front suspensions bushings became torn. The car did not present any warning lamps or warning messages. The issue became apparent when a loud creaking/squeaking sound started coming from the front of the vehicle, and could be reproduced by turning the steering wheel, or by accelerating or braking. Control arm and suspension failures have been a frequent issue amongst Tesla owners, and the NHTSA should consider a recall for the design flaw.

 A little background information, on Dec 2023 I installed 4 new Hankook Ion Evo AS (255/45R19) for my Tesla model Y at the Correa Tire shop in Dorado Puerto Rico and the manufacture date on those tires was 4422 and at the time the car had close to 30k miles.  On April 2025 one of the tires broke and I replaced it at the same place with the same tire model.  Less than a month after the new tire was installed, while riding on the highway at close to 65mph the recently replaced tire completely broke off leaving only the sides and the rest of the tire flew off the car (see pictures attached).  This happened suddenly with no previous indication or car notification of any issue with the tire.  Fortunately, I was able to stop the car without losing control and apparently the tire did not hit other oncoming cars.  This was a very scary situation, which could have resulted on a serous and even fatal accident.  When I checked the new tire, or what remained of it, I noticed it had the same manufacturing date (4422) as the tires I had replaced in 2023. The next day I went to the tire shop and explained the incident and they informed I had to buy a new tire while they investigated the situation and if there was any issue with the tire. At that time I also opened a complaint with Hankook US. After waiting various weeks for a response, and expecting reimbursement for the damage tire, I have not received any information from the tire shop and Hankook said they did not receive a claim from the tire shop.

Low beams are too bright and aimed too high, constantly blinding other drivers. Automatic high beams are always turning on and will not automatically turn off when another vehicle is detected.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The 12V battery failed unexpectedly, causing a complete shutdown of the vehicle. The car became fully inoperable—doors, windows, touchscreen, and manual override systems were unresponsive. Yes, the vehicle is available for inspection. 2. How was your safety or the safety of others put at risk? My young child was inside the car at the time of the failure. Due to the system lockout, I was unable to open the doors or remove them from the vehicle. Emergency responders were called and had to break windows to safely extract my child. This situation posed a serious risk of heat exposure, panic, and injury. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The failure has been documented and attributed to a dead 12V battery, though Tesla has not formally inspected the vehicle as of this writing. I am working to have it evaluated by a qualified technician to confirm the cause. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was not inspected by Tesla at the time of the incident. Emergency responders did assess the situation on site. I plan to notify my insurance provider, and will make the vehicle available for inspection. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No. There were no alerts, notifications, or warning lights indicating the 12V battery was low or nearing failure. The malfunction occurred without warning.

Steering assistance reduced alert is showing up on vehicle. It is difficult to drive the car. The car has less than 33,000 miles on it.
