2018 TESLA MODEL 3 Complaints

After an over the air software update this past week 2026.14.6 my Tesla Model 3 power steering has failed. EPAS shows ACTICE in service mode, calibration was successfully completed and there are no active EPAS/rack faults. Power steering assists at higher speeds but fails below 20mph. Tesla has a history of steering related software problems and needs to take ownership of the problem.

Tesla model 3 2018 long range 86k miles. While driving 50mph on freeway the lower control arm link separated from the frame. No impact, no damage, and no pothole/bump. Lost steering and was able to get to side of road. When I got out and look at vehicle the control arm was disconnected from the frame. The frame showed no damage and the control arm showed no damage. The mounting holes for each here intact and no damage. Appears that bolt fell out or sheared off and the control arm disconnected. This is a safety failure and was scary. I towed to Tesla and they claim that failure was form worn parts and tolerances. I stated how could this be worn parts when mounting holes are in excellent condition. They are refusing to help with cost of repair and quoted me $2800. They are not taking responsibility and I believe that others should know of this failure. I believe I am being wronged and would like to report. Thanks.

Potential safety defect: high-voltage battery and battery management system (BMS) appear to overestimate available energy and remaining range, creating risk of unexpected 0% state of charge or loss of motive power without warning. Across 20 documented charge/discharge cycles between January and May 2026, the vehicle has consistently delivered approximately 135-150 miles of real-world range against an EPA-rated 310 miles, under routine driving conditions. The vehicle's own energy display shows observed usable energy averaging approximately 49.93 kWh -- approximately 66.6% of the rated 75 kWh pack. Tesla/BMS diagnostics report approximately 79-80% pack retention, implying approximately 58-59 kWh available -- approximately 8-9 kWh more than the vehicle's own consumption display reflects. No BMS fault code, low-power alert, or driver warning has been generated despite this persistent discrepancy. On April 22, 2026, after a drive, the vehicle was parked showing approximately 3% SOC and 7 miles remaining. Approximately five hours later, while parked and not being driven, the vehicle displayed 0% SOC and 0 miles. No fault or warning was triggered. Supporting photographs document the same low-SOC discharge cycle: vehicle at 27%/65 miles on April 20 and at 0%/0 miles on April 22. A driver relying on 3%/7 miles as a margin to reach a charging location could become unexpectedly stranded. If a similar BMS recalculation occurred while driving at low SOC, the result could be sudden unexpected loss of motive power -- a potential roadway safety hazard before the driver receives adequate warning. On May 14, 2026, Tesla Service performed a battery health review (Invoice 3000S0016915237) documenting 79% pack retention, no faults found, no further action. Test name, methodology, and whether the review evaluated BMS calibration accuracy or low-SOC energy availability were not disclosed.

The control arms on all make and models of tesla have a horrible design that all water off of the car flows down the sides of the front hood and down onto the control arm bushing. This could be a simple fix for tesla to out a boot on it to cover the bushing. The control arms start to fail at any given time. This is costing owners thousands of dollars. I have had to had them replace once under warranty and now they want me to pay 2000 since I am out of warranty. Owners with newer vehicles sometimes start to have problems within the first year. This part design needs to be recalled and all persons have free repairs. According to sources, driving with severely worn control arm bushings can lead to a fatal accident. While bushings often start as a minor nuisance, complete failure compromises the structural integrity of your vehicle's suspension. Don't wait till deaths start happening. Protect the customer and others and send a recall on this. Yiu can Google tesla control arm issues and and see over and over in videos and forums that this is a major issue.

Within the last 7 days, my 2018 Tesla Model 3 Long Range AWD began displaying active alerts for two separate safety system failures: (1) alert code UI_a020 / GTW_w075 — Steering Assist Reduced, stating steering may require increased effort, and (2) alert code RCM_a056 — Front Passenger Safety Restraint System Issue, requiring service. The steering alert appeared intermittently, firing at consistent times of day suggesting a possible electrical or sensor fault rather than mechanical failure. On one occasion during startup, the steering system briefly locked up before resuming normal function. No noticeable change in ongoing steering feel has been observed while driving. The passenger restraint system alert indicates the front passenger airbag and Occupant Classification System (OCS) may not function properly in the event of a collision, directly endangering any front passenger. Both issues have been confirmed by the manufacturer via remote diagnostic review, and two separate service estimates totaling approximately $4,784 have been issued recommending replacement of the steering rack, front passenger airbag, occupant classification sensor, seat harness assembly, and seat cushion assembly. Notably, the manufacturer has not physically inspected the vehicle — both estimates were generated solely based on alert codes read remotely and "AI" according to a representative. The manufacturer's own customer support system indicated these repairs may qualify for goodwill coverage, yet no formal commitment has been made. The passenger airbag and restraint system failure is of particular concern as it represents a potential inability of a primary safety system to deploy correctly in a crash event. The component is available for inspection upon request. The vehicle has not been inspected by police or insurance representatives. Warning alerts remain active and ongoing.

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.

When using FSD in "chill" mode the car attempted to cross over into oncoming lane on a two lane highway. There were no oncoming cars and I overrode the car almost immediately. The car has not been inspected by anybody. No warning light, messages or other symptoms. I have a video of the incident for a Viofo dashcam installed in the car.

The front lateral links, compliance links, and stabilizer bar link on my 2018 Tesla Model 3 Long Range failed and required replacement in January 2026. Prior to failure, abnormal creaking and clunking noise from the front suspension began appearing weeks before the repair — no warning lights illuminated at any point. The failed components were replaced by a Tesla-certified Service Center and are no longer available for inspection. The failure was confirmed and repaired solely by the Tesla Service Center; no police, insurance representatives, or other parties inspected the vehicle. I was charged out of pocket for this repair. The lateral link separation risk directly endangers vehicle safety — if a fastener loosens sufficiently, the lateral link can detach from the subframe, causing sudden wheel misalignment and loss of steering control, which could result in a crash at any speed. Tesla issued recall 23V-235 (NHTSA campaign 23V235000) in March 2023 for this exact condition on 2018-2019 Model 3 vehicles. My vehicle's VIN was not included in the recall population, yet experienced the identical failure mode. I am requesting this complaint be considered for recall expansion under 23V-235 and seeking reimbursement for out-of-pocket repair costs for a defect Tesla has already acknowledged in identical vehicles.

Following a professional suspension repair at a Tesla Service Center, critical underbody fasteners (bolts) became loose, causing the aero shield to sag and creating a potential road hazard. Upon inspection, the service technician confirmed the bolts were unsecured. The failure of these fasteners on a safety-critical system poses a risk of parts detaching while in motion or loss of vehicle control. The service center refused to acknowledge this as a workmanship failure under the 12-month repair warranty, despite the fasteners being last serviced by their technicians.

Pantom braking happening frequently after latest software update. FSD version 12.6.4 Software version 2026.8.6 Happening on single lane road.
