Your Lexus is well-known for its outstanding features, sleek design, and exceptional performance even in extreme climatic conditions. Despite having a high tolerance, your Lexus might face electrical failures over time if not addressed effectively. Can you imagine how harsh it could be if your Lexus encounters electrical issues in the brutal weather conditions of Phoenix? The air conditioner suddenly blows warm air into your car cabin, the stereo stops playing your favorite tunes, the infotainment fails to show the navigation, the headlights start dimming, and the power windows plus other remaining electrical components stop working, due to a faulty electrical system. What will you do in such a helpless situation? Don’t panic! Like every lock has a key, every problem has also a solution. Let’s find out the solution together.

Seek shade or a cool environment for car parking

You must park your Lexus under a shade or in a parking lot whenever possible because the scorching weather of Phoenix can destroy the battery’s health and hamper the function of other electrical in-car gadgets. Parking in a cool place significantly reduces sun exposure and prevents the electrical components from overheating. Remember to inspect the coolant level and change the coolant according to the manufacturer’s manual periodically, to avoid excess heat generation from the engine and safeguard electrical components from getting fried.

Routine checkups for battery and alternator

If the headlights are dim or the engine is cranking slowly, immediately test the battery’s voltage with a multimeter. If the reading is less than 12.6 Volts, the battery is weakening, and you need to replace the battery with a new one. You may hear an abnormal whining sound or notice the battery warning light blinking on the dashboard if the alternator is malfunctioning. As the battery is the heart of the electrical system and the alternator provides electrical charge to the battery to run the engine, ensure both are free from corrosion. Keep the battery terminals clean and tighten them with proper torque. You can use the mixture of baking soda and distilled water plus a brush to remove unwanted deposits from the battery terminals, if any.

Maintain wires, connectors, and fuses

Inspect the wires and connectors for any signs of damage or loose connections. If any, fix them immediately, as they are the paths for the electric charge to move. Since fuses are the components that protect the electrical circuits, you need to check them periodically and replace them if blown or misfired. Focus more on the areas that are exposed to heat and moisture because Phoenix’s hot weather and sudden raindrops can enter the electrical components through headlights or other exposed areas, causing short circuits plus other electrical failures by building up the moisture. If you notice any leaks, fix them immediately with the help of a technician.

Monitor lights periodically

Inspect whether the headlights, brake lights, taillights, and interior lights illuminate with genuine intensity. Remember to replace the burn-out bulbs, if any. Always keep your light covers clean to enhance the visibility and intensity of the light. Don’t avoid the dashboard warning light, as your Lexus has a feature of onboard diagnosis that automatically investigates various electrical components. You may use an OBD-II Scanner or get professional assistance to read error codes for spotting the exact issues.

Miscellaneous preservation guidelines for your Lexus electrical system

• Use OEM (Original Equipment Manufacturer) parts or reputable aftermarket parts suitable for your Lexus model while replacing the electrical auto parts. Don’t use cheap parts to save money, as they can jump to bigger issues in the future.
• Don’t park your Lexus near areas with high rodent activity, as the rodents can enter your car for shelter and in return, can chew or scratch the electrical wiring, leading to costly repairs. You can use rodent repellents to keep the wires safe.
• Modern Lexus has an advanced computer system that needs regular software updates to automatically fix bugs and upgrade performance. Keep your Lexus computer system updated so as not to face any software glitches.
• Don’t keep your Lexus idle or avoid short driving habits, as this drains the battery’s charge too early. Go for long trips at least once a week to keep your battery fully charged. You may use a battery maintainer to keep the battery charged if you don’t drive your car for a long duration.
• It’s better to visit the workshop and get the mechanic’s help. But you must educate yourself about minor electrical problems and how to deal with them, so that if you encounter any issue meanwhile a journey, you can fix it by yourself without pissing off your peace.
