Tesla Model 3 loss of power problems

Filed Sep 23, 2026 · Steering · WA

The vehicle reported an error with steering. I brought the vehicle into tesla service. Upon inspection the connector to the steering rack was heavily corroded from water intrusion and had broken clean off upon removal. Confirmed with dealer that corrosion had caused the issue. If the connector had failed while driving the vehicle would have lost all power steering immediately and placed myself and others on the road in danger. The connector was corroded enough that the spade connector detached completely upon inspection. The steering rack is not easily accessible by the consumer and could not have been impacted by circumstances outside of normal driving.

While my wife was driving, the high-voltage battery failed and the car went into reduced power/limp mode. Tesla later determined that coolant had gotten into the high-voltage battery and caused it to fail. My main concern is that we had no warning that there was a coolant leak or that coolant was getting into the battery. There was no low-coolant warning or anything telling my wife that there was a serious problem developing. By the time the car started giving high-voltage and reduced-power warnings, the damage had already occurred and Tesla said the battery needed to be replaced. What concerns me even more was what happened after Tesla received the car. Tesla removed the battery and quarantined it in the parking lot. They told us in writing that it was removed because of coolant ingress as a safety precaution and that a specialized technician had to determine whether the battery was safe to discharge. During a phone call, a Tesla employee also told me they quarantined it because there was a possibility the battery could explode and they did not want anyone injured or anything damaged if that happened. That was alarming because my wife had just been driving this car, and afterward it sat in our driveway while we waited for it to be taken to Tesla. At no point were we told that the battery could be dangerous or that the vehicle should be kept away from people or property. We had no idea Tesla would consider the condition serious enough to quarantine the battery once they received it. Tesla later confirmed in writing that coolant ingress was the root cause of the battery failure. I would like the federal safety agency to look into why this condition was able to get this far without warning the driver and whether other vehicles could have the same issue.

I am getting an electrical fault which has disabled my front passenger seat airbags. They need to replace the wiring, which means they also now need to replace the passenger airbag itself because wiring has changed and the old airbag is not compatible with the new wiring. Replace Occupant Classification System (OCS) of Front Passenger Seat while Servicing Subcomponents Update Front Passenger Airbag to Maintain Compatibility with Front Passenger Seat I had this same error 4 months ago and it ended up shorting out the entire electrical system, which disabled autosteer and eventually completely disabled power steering which made the car unusable. Tesla service center called it a water intrusion problem and had to replace the entire front electrical harness system and steering rack costing $4500. Now the problem has resurfaced and I'm afraid I might lose power steering again which is extremely dangerous and could happen any time, in addition to my airbags potentially not deploying.

While making a right turn from a near-stopped position, the steering wheel became stuck or extremely difficult to turn. The vehicle initially turned right normally, but when I attempted to steer back left/counterclockwise to complete the turn and straighten the vehicle, the steering wheel did not respond as expected. This caused the vehicle to continue in the wrong direction and resulted in a collision. I believe the electronic power steering assist system malfunctioned or failed. My concern is that the power steering assist experienced an overstress condition, causing a loss of power steering assist after the vehicle almost reached a stop and then accelerated again. This put my safety and the safety of others at risk because I was unable to steer the vehicle as intended during a low-speed turning maneuver.

My RWD motor completely went out and lost power on the highway off ramp. Could have turned into a dangerous situation. Not sure why these motors seem to be very unreliable. Tesla has not given me an explanation as to what is exactly causing this. Happens to thousands of owners. And this car is only 5 years old. I had the motor replaced in November 2022 and 3 years later it’s out for good. Now I have to deal with teslas insane costs. I feel like they sold me a defective car.

Safety Issue: Defective interior cabin camera causes Tesla Full Self-Driving (FSD) to disengage abruptly and without adequate warning at freeway speeds. I am a [XXX] driver. I purchased FSD capability with this vehicle in December 2018. In October 2025, I had the FSD hardware upgrade (HW2.5 to HW3) installed at Tesla's Encinitas, CA service center (B.A.R. License [XXX] ). Within days, FSD would became completely unusable due to a recurring "Cabin camera unavailable — schedule service" alert that instantly disengages the system. The disengagement occurs on the freeway at highway speed, without meaningful advance warning. As a [XXX] driver, the sudden loud alarm and loss of assisted driving is genuinely alarming — it is not immediately clear in the moment whether the vehicle has lost power or experienced a critical failure. This is exactly the kind of dangerous situation driver assistance systems should prevent, not cause. Tesla's own diagnostic confirmed the defect (Diagnostic Invoice No. XXX, November 27, 2025, Encinitas service center): "Cabin camera unavailable" alert verified Intermittent stream exit faults detected in the selfie/cabin camera Low-voltage circuit and wiring checks were normal — ruling out wiring Conclusion: fault is within the camera module itself; technician recommended replacement The defect is FSD-specific. The cabin camera works correctly for Sentry Mode, live security viewing, and all normal driving. It fails exclusively when FSD is engaged and demands sustained driver monitoring. The camera housing also becomes extremely hot to the touch during FSD use, consistent with reports from other 2018 Model 3 owners describing identical symptoms after their HW3 retrofits.

Door cannot be opened during power loss / emergency. I am a Tesla Model 3 owner in California. I discovered that the rear doors do not have a mechanical emergency release. Tesla service confirmed that my vehicle does not include any manual rear emergency door release system. This raises a serious safety concern because, in the event of a crash, fire, or 12V power failure, rear passengers—especially children or elderly occupants—may be unable to exit the vehicle. I request the federal safety agency to investigate whether the absence of a mechanical rear emergency release complies with FMVSS 206 and whether Tesla’s design poses a safety risk during emergency egress.

During a head-on collision on [XXX] in Georgia, the electrical system in my 2022 Tesla Model 3 lost power and the electric door releases stopped functioning. The vehicle interior caught fire and I was trapped inside. I was unaware of the location of the hidden mechanical emergency door release because it is not visibly labeled, not explained upon delivery, and not intuitive in an emergency. I was forced to climb to the back seat and break the rear passenger window with my legs to escape while the interior was burning. I suffered a broken hip, broken arm, and later required a full hip replacement. The mechanical emergency door release was concealed and unlabeled, resulting in entrapment during a fire, which is a violation of FMVSS 206 and presents a continuing and life-threatening safety hazard to all drivers and passengers. Tesla has not provided warnings, recall guidance, labeling, or owner education regarding how to exit the vehicle during a power-loss emergency. This defect can result in deaths. I am requesting a formal investigation. DP25002 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
