All models: weak A/C cooling and noise — clogged condenser/radiators (how to clean)

On Teslas the front radiator stack quickly fills with fluff/dirt. The condenser sheds heat worse — the compressor runs at maximum and dies sooner. Solution: regular cleaning (with safe methods).

Suspension calibration in Service Mode after repair

After replacing arms or shocks, suspension calibration via Service Mode is mandatory. Without it — error on the screen.

Window regulator not working — diagnosis and repair

Window regulator fails: window won't go up or drops on its own. Calibration, reboot and mechanism replacement.

Model S/X: LDU problems (the large rear motor) — seal leak and failure

Typical defect: coolant leaks past the rotor seal → ingress into the stator/inverter, noise/corrosion and motor death. What to check, how to fix it, and what it costs in Belarus.

Model 3/Y 82 kWh Panasonic (US): frequent module imbalance

American 2021–2022 LR cars show frequent imbalances; treated by replacing modules/the pack. An alternative — replacement with LG 79 kWh.

Autopilot and camera calibration after repair

Traffic light recognition needs HW 3.0+. After body repair, camera calibration via Service Mode is mandatory.

Coolant bleeding — removing air after repair

After coolant system repair the coolant doesn't circulate due to an air pocket. How to bleed it via Service Mode.

Model 3/Y: front creak/crunch when steering or over bumps — upper control arm (ball joint)

The classic 'old cart' creak at low speed and during steering changes. Most often the front upper control arm is at fault (the ball joint in the 'horseshoe'): grease leaks out, the ball goes dry, and a creak appears. What to do as a temporary fix (syringe/grease) and how to solve it properly (replace with the updated arm).

Model 3/Y refresh 2021: heat pump issues (sensors/PT-sensors, software)

On the 2021 refresh there were widespread failures in heavy frost. Software updates and service campaigns (PT-sensor replacement) improved the situation.

Model 3/Y pre-refresh: cabin PTC heater failure

A frequent failure of the pre-refresh PTC heater (aggravated by a clogged filter and constantly running at maximum).

Model S/X 100 kWh: voltage sense harness tab failures

On 100-kWh batteries, voltage sense harness/tab failures on modules occur → BMS errors, pack shutdown. What to do and how much it costs in Belarus.

Model S/X 60/70/75: low pack voltage and limits at 50 kW/125 A chargers

Due to the lower voltage (≈350 V and lower at low SoC), power on 125 A DC chargers is limited to ~35–40 kW. This is normal.

Model S/X 85 kWh: stuck air valves and moisture ingress into the battery

Old 85-kWh packs are prone to corrosion/leaks through valves/fuse cover → BMS errors, HV shutdown. What to look for and how to fix it.

Model S/X 90 kWh: faster degradation than 85

90-kWh packs (NCA with silicon added to the anode) per owner reports degrade faster than 85. Fewer typical 'fatal' defects.

S/X: certificates and app connectivity — how to check

Model S/X (Raven and newer): shudder/vibration under acceleration — front halfshaft wear

Characteristic vibration ('shudder') under intense acceleration — a frequent story on S/X Raven+. The cause lies in the front halfshafts and CV joint angles on air suspension. We cover how to fix it per Tesla bulletins and what repair options are available.
