Battery failure, low coolant level. According to the request, it is displayed on the road network.
1. This is caused by loose connections or sulfation (the buildup of lead sulfate crystals on the plates of lead-acid batteries). When sulfate molecules in the electrolyte (battery acid) are discharged too deeply, it can cause scale to build up on the battery plates, preventing the battery from delivering enough current.
2. Without radiator coolant, the engine will quickly overheat, leading to mechanical failure and engine failure. The coolant level should be checked regularly and visually inspected for any puddles of coolant.
