multiple warning lights on dash Page 411

Seeing a constellation of warning lights on your dashboard is about as welcome as a spider in your bed. Multiple lights can indicate anything from a faulty sensor to more serious electrical or engine issues. Common culprits include a failing alternator, low battery voltage, or a glitch in the vehicle's computer system. It's best to check the vehicle's manual and use an OBD-II scanner to pinpoint the exact problem.

• Dead or weak battery
• Faulty alternator
• Loose or corroded wiring
• Sensor malfunctions

Ignoring these signs is like playing Russian roulette with your car’s health—get it diagnosed ASAP. Used car buyers can find vehicles with such issues listed on sites like Tradingpost and CarShowroom, but beware the potential repair bills.
