On the 2017-2019 Chevrolet Onix, gM do Brasil recalled Onix and Prisma (along with Cobalt and Spin) vehicles produced between 2016 and 2018 — model years 2017 to 2019 — plus vehicles that received genuine GM replacement fuse boxes in 2018, because the underhood fuse box relay terminals could be installed without adequate insulating protection. Water entering and accumulating at the relay terminals in the engine compartment can cause a short circuit that triggers involuntary, continuous activation of the starter motor. The constantly-engaged starter can overheat to the point of fire, and on a manual-transmission car left parked in gear the cranking starter can move the vehicle on its own. The fix is a 20-minute free service in which the dealer applies insulating sealant to the fuse box relay terminals.

Common Symptoms

  • Starter motor cranks by itself with the key out
  • Clicking sounds from the underhood fuse box after rain or washing
  • Burning smell from the engine bay
  • Car lurches or creeps while parked in gear
  • Intermittent no-start or electrical faults in wet weather

How to Fix

Check recall completion by chassis number on the Chevrolet Brasil recall portal or by phone (0800 702 4200); the insulation service is free and takes about 20 minutes. Warning signs — the starter cranking by itself, clicking from the underhood fuse box after rain or engine washing, or a burning smell — mean the car should be parked away from structures, the battery disconnected, and the dealer service performed immediately. Never leave an unrepaired manual-transmission car parked in gear.

Typical repair cost:$0 - $0
