Battery drains quickly: separate charge, health and electrical draw
Repeated battery discharge may relate to charging, battery condition or an electrical load while parked.
Fuel efficiency
Fuel consumption has increased: how do you confirm it and begin checks?
Start by establishing increased litres per distance, not a higher refuelling bill.
Cooling and air conditioning
Why does a vehicle overheat in traffic?
Overheating while stationary that improves in motion points towards checking heat rejection and airflow, but does not establish that the fan alone is faulty.
Engine and maintenance
High RPM at idle: causes of a high idle speed
Elevated engine speed after a cold start differs from speed remaining high after operating temperature is reached.
