Leading Repair Shop in Birmingham to Tackle Lexus Battery Draining Issue

Lexus cars are known for their high performance, stylish design, and ultimate comfort. However, just like any other vehicle, your luxury Lexus can also experience typical car troubles, such as battery depletion, which can lead to slow or no ignition, leaving you stranded on the roadside. Rather than having to jump-start your car with jumper cables to recharge your battery repeatedly, ensure it stays charged with regular maintenance and timely replacement repairs. If you’re unsure whether your Lexus has a battery-draining issue, we’ve provided an educated list of potential causes and symptoms to watch out for, so you can have peace of mind.

Why Your Lexus Battery Drains: Causes and Symptoms

Parasitic Power Loss from Electronics

First, it’s important to understand what a parasitic battery drain is. This phenomenon involves your car’s electric components, such as the infotainment system, dome lights, or onboard computer system, constantly using the battery charge, even after the engine is turned off. When this happens overnight, it results in a dead battery. Sometimes, in case of heavy parasitic drains, the battery loses power even if you park it for only a few hours. It’s easier to spot these issues than others; if you notice that the interior lights, infotainment systems, or dashboard displays fail to power down correctly, then you’re likely encountering this issue. The most challenging part is determining whether the battery drain is constant or irregular. Instead of trying to decipher it yourself, our experts can perform diagnostic tests to identify hidden power drains, replace and repair whatever is needed, and ensure you never face this issue again.

Faulty or Damaged Battery

When the battery is older than 3 to 5 years or damaged, such as by corroded terminals or a swollen battery case, it’ll fail to hold a charge, particularly in cars with heavy electrical loads, like those from Lexus. In this case, you may encounter issues such as poor engine cranks, dull interior lights, and headlights. Your vehicle may even require repeated jump-starts, or glowing or blinking dashboard warning lights related to battery or charging system troubles. Apart from these alerts, you may also detect an unpleasant, rotten egg-like odor due to seeping chemicals. If this happens, we’ll first test the battery voltage using a multimeter. If it’s caused by a weak battery, then we’ll recharge it and run your car to identify the source of the battery drain. Otherwise, if it’s the battery itself, we’ll replace it directly with a correct, high-quality unit to ensure peak vehicle operation in the long run.

Alternator Malfunctions

The alternator is responsible for continuously charging the battery as soon as the engine starts running. So, when it develops any troubles, the battery fails to charge, and your vehicle experiences dreaded issues like an activated battery or charging system-related alert lights, flashing dashboard lights, dysfunctional electrical components, and abrupt engine stalling. Moreover, you may also hear unusual sounds and notice the battery draining quickly shortly after starting your Lexus. Reaching out to us can be beneficial for you, as our specialists can test the alternator and pinpoint the issues, and then take the necessary actions to repair or replace it according to the requirements.

Dysfunctional Door or Trunk Buttons

These switches are meant to turn lights on or off when the doors or the trunk are opened. When these buttons malfunction, the door or trunk indicators will stay on even if both are correctly closed. Even though this is a slow burn due to the minimal light being emitted, it’ll still constantly drain the battery. This also creates confusion about whether the doors or trunks are adequately locked or not. Additionally, you may also hear chimes or notice warning notifications displayed on the dashboard, even after repeatedly locking the doors and trunk. We understand how frustrating it can be to see warning messages appear on the screen constantly. To remedy this, we’ll use our top-of-the-line diagnostic scanner to read the error codes and identify the root of the issue. Once we’ve determined the culprit as a faulty switch, we’ll replace it with a new one to get everything back on track.
