Why is my Star EV BN72-14-AC-D locking control when vehicle starts running?
- Z
  Zachary RomanAug 17, 2025
  If the control locks when your Star EV Automobile starts running, preventing speed adjustment, it could be due to several reasons. The terminals of the solenoid might be sticking together (check or repair), there could be a controller failure (change), a potentiometer failure (repair or change), an internal short of the motor (repair or change), the motor is assembled too tight or blocked (repair or change), an accelerator failure (repair or change), or there might be normal power at low speed, weak power at high speed (check or change).

- K
  Kayla LongAug 25, 2025
  An abnormal sound when your Star EV Automobile is running (specifically from the transmission system) can be caused by several factors. The clearance of the rear axle decelerating gear might be too big, or the decelerating gear could be broken (adjust, change). Alternatively, the transmission cross shaft could be worn out (change), the gear of transmission could be worn out or damaged (change), the flange bearing could be damaged (change), the motor bearing could be damaged (change), or the gear liquid could be deficient or empty (add gear liquid).

- H
  Heather JohnsonAug 28, 2025
  Heavy steering in your Star EV Automobile can be attributed to a few potential issues. The pressure of the front tire might be deficient (check the pressure and inflate). It could also be that the screw plug of the redirector is too tight (adjust), there's a lack of lube in the redirector (maintain/add lube), or the toe-in is abnormal (adjust).

Why is my Star EV BN72-14-AC-D deflected running?
- J
  Joshua CamachoSep 4, 2025
  If your Star EV Automobile is deflected running, it could be due to several reasons related to the driving system. The pressure of the two front tires might be different (inflate). The toe-in could be too big or too small (adjust). The tightness of the left and right drum bearing of the front wheels might be different (adjust). The brake of one wheel could be too tight (adjust or change). The spring shock absorber might be abnormal (change), or the front suspension could be loose (change).

What causes braking drag in Star EV Automobile?
- C
  Christine ZamoraSep 8, 2025
  Braking drag in your Star EV Automobile could stem from several issues within the brake system. The brake pedal might have no free travel (adjust). The clearance between the brake shoe and drum could be too small, or the releasing spring might be disabled (adjust or change). The piston of the wheel cylinder might be ineffective (check or change). The piston of the master cylinder might be ineffective (change spring), or the parking brake could be ineffective (change spring).

What to do if my Star EV BN72-14-AC-D Automobile doesn't move after turning it on?
- T
  Thomas GuerreroNov 12, 2025
  If your Star EV Automobile doesn't move after turning the power key and pressing the accelerator, there are several potential causes. It could be due to loose or open connectors in the circuit (tighten or connect them), an open fuse in the controller or main circuit (change the fuse), loose or disconnected battery cables (tighten or change them), a broken power key (change it), a broken voltmeter (change it) or improperly connected battery terminals (adjust them). In some cases, it may be due to an improper operating procedure (operate properly), controller failure (check or change it), solenoid failure (check, repair, or change it), accelerator failure (repair or change it) or motor failure (repair or change it). Also, make sure the parking brake is loosened and that there's no over-heat ...
