2018 TESLA MODEL 3 Complaints

RCM_a021 alert: Front left safety restraint system fault. Seems like an issue caused by seat movement back & forth.

On March 21, 2025, my Tesla Model 3 Long Range entered "Power Reduction Mode" — a safety feature that limits power to protect the high-voltage battery from overheating or failure. Tesla later diagnosed a coolant leak near the battery area. Their own service advisor stated in writing that the failure was “most likely related” to the battery’s thermal management system — the very system responsible for regulating battery temperature and preventing damage. Despite the connection to the battery protection system and the vehicle being under the 8-year/120,000-mile battery warranty, Tesla has refused to cover the repair. The issue remains unresolved, and I have not picked up or approved any repairs on the vehicle. My concern is that driving the vehicle in this state — or leaving this failure unaddressed — could lead to further battery damage or pose a safety risk. I am requesting that NHTSA evaluate this issue as a potential safety concern, especially as the manufacturer is refusing to repair a system directly linked to high-voltage battery safety.

While regularly driving I experienced a gradual squeaking sounds from the front suspension. A few moments later I noticed that my steering wheel was acting as if it didn’t have power steering. I’m lead to believe that due to the poor design of my Model 3, that the outside elements were easily able to make its way to my Universal power steering shaft leading Tesla to remove and replace my steering shaft and my Upper control arms as well. The rust on the U shaft was incredible, I’ve only driven in the snow one time and immediately the noises starting happening. I paid everything out of my own pocket due to the undeliverable conditions my steering wheels was in.

I received and indicator noting that my front passenger safty system has a fault. They indicated that they will have to replace the seat sensor and the airbag. I believe this to be an innate fault of the cars construction. It is dangerous and should be fixed by Tesla and not charged to the customer.

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.

This is a widespread safety issue that requires a recall! This is not isolated. Model 3 passenger airbags are at risk of not deploying.

Car performed automatic emergency braking on driver's resumption of forward travel from a full stop when traffic light went from red to green. No oncoming vehicles or obstacles were present. Weather was clear and sunny and road was dry.

Right front upper control arm began making noise and was replaced under warranty at 42k miles in Sept 2019. Left front upper control arm failed around 50k miles and caused a wreck resulting in $8,365 in damages in April 2021. When fixing one side it is standard to replace the other and Tesla was negligent. Upon fixing the left side suspension at Blue Ash Auto Body in 2021, the brake caliper came loose while driving on the highway while on a vacation. This caused an additional $1500 or so in charges. Both of these incidents put my life and my son's life in danger. About a week or two after the caliper problem, Tesla issued a recall for that part stating that it is now single use only.

- component or system failed or malfunctioned - Front Subframe Structure (Part Number 1044521-00-J) - the part failed with my car at approximately 55,000 miles. When it failed, the car didn't alert any problem and continue to drive the full-self-driving mode. I only noticed that it was very dangerous the next day when I tried to take my car out of the garage. - the problem was diagnosed by Tesla Service center which I had to toll my car to them because it was unsafe to drive. - The vehicle or component was not inspected by police or insurance, because there was no accident. - There was no warning lamps or indication other than noise.
