Electric car repair and maintenance

Problem: The owner of a second-generation Nissan Leaf contacted STS.Electro with a complaint: the car only charges from a fast charging station, but does not accept a slow charging gun (Type 1).

Problem: We were contacted by the owner of a Peugeot e-208 electric car. After charging to almost 100%, the electric car stopped accepting a charge, and the system displayed a second-level overvoltage error.

Problem: The owner of a Karma Revero hybrid was unable to drive his car for over eight months: the engine would only start for a few minutes at a time, and the battery would not charge.

Problem: The Dacia Spring car would not start or charge due to a reversed battery polarity and a faulty DC/DC+charger unit.

Problem: A well-known logistics service provider brought in three electric vans for repair after their high-voltage batteries failed. In one of them, the battery was dismantled.

Problem: The high-voltage battery is discharged and cannot be charged. The car does not accept a charge because the electronics do not recognize the connection of the charging gun.

Problem: A sharp drop in driving range and the vehicle switching to emergency mode with reduced power (“turtle mode”).

Problem: The problem with the car was the incompatibility of the Chinese GB/T standard charging system with European charging stations. This created difficulties for the owner of the Audi Q4 e-tron, since the car, produced for the Chinese market, could not charge at European stations with the required speed and reliability.

Problem: Failure of Toyota hybrid batteries is a common problem that our customers come to us with. The battery cells degrade, making it impossible for the car to operate normally.

Problem: We received an electric car with very discharged traction batteries. The problem is typical for the Fiat 500. During idle time, the batteries discharged below the permissible level, and the car's electric motor stopped starting.

Problem: The Hyundai Kona made a rather loud noise. The customer diagnosed the malfunction on his own - in his opinion, the gearbox was the cause of the extraneous sounds.

Problem: We received an electric motor manufactured by Continental, which was installed on an Opel vehicle for the Chinese market. The motor seized after the car was involved in an accident.

Problem: There was water and rust inside the rail, which damaged both the needle bearing in the cover and the torque sensor, i.e. both the mechanical and electrical parts

Problem: Two electric vehicles arrived at our workshop: a 2018 Kia e-Soul with noise in the motor area and a Mercedes-Benz EQC with an "insulation fault to ground" error. In both cases, the faults turned out to be quite typical and caused by design flaws in the vehicles.

Problem: We received a Hyundai Ioniq EV with complaints of whining noise during driving. An initial inspection revealed that the sounds are coming from the motor, on the side opposite to the gearbox.
