First, we will try to find the reasons that might prevent your car from starting.
It is also possible that your car crancks but won’t start.


Reasons that prevent your Lexus RX from starting

The battery may not have supported leaving your headlights on all night, or the vehicle key may have been forgotten on the ignition.
To make sure that it comes from the battery, and not from other causes, first examine the lighting of your headlights. Indeed, a low intensity or no lighting would be a bad sign for your battery.

Let’s see the different causes of failure

Battery pack of your Lexus RX

In most cases, for a Lexus RX that does not start, the battery is implicated because it gives the starter the energy needed to start the engine.
Verify if there are any lights on your dashboard. Refer to the light on to indicate the failure.
If when turning the key you can feel jolts, this is a sign of a low battery, and consequently it needs to be recharged.
A little trick that could help you a lot is to keep jumper cables in your Lexus RX, you will save yourself a towing.
If someone you know has the cables themselves, they can recharge your battery enough for you to restart the engine and the battery to recharge itself. Wait for a moment before departing even if your car is on, you don’t wish to stall at the first traffic light and have to perform the operation.

Weather conditions

Let’s go forward. Let’s imagine that your battery is recharged, but sadly your Lexus RX still doesn’t start. First, it is crucial to know that humidity and temperature changes generate oxidation that can deposit on the battery terminals, clogging it and preventing it from working.
When in good working order, the terminals are a metallic grey. If they have changed colour, it is necessary to clean them. It is possible to do this with a wire brush or sandpaper. Apply a small amount of thick grease before rubbing.

Starter of your Lexus RX

Now you have put into practice our advice so far but your Lexus RX still doesn’t react. It is now time to focus your attention on the starter, the small electric motor that starts the car’s engine.
You should know that to keep it in perfect working order, a few simple and quick steps are required. You can give a few small jolts on the sharp part of the starter, which will release the coals and assist in their passage.
It should also be noted that this part does not have a specific lifetime, everything will be based upon its use and consequently on the maintenance of your Lexus RX. When it no longer works well, it is often caused by a bad electrical contact, itself often caused by high summer heat. This lowers the conductivity of metals. If the weather is not hot, it is notto be blamed for

Another technique to try to launch your car is to put your Lexus RX on a slope and by using the clutch pedal, the engine will eventually start. This will succeed if your battery is dead and it has not been used to start the starter. In this solution, this trick avoids solliciting it.

Alternator of your Lexus RX

If, on the other hand, after driving, your battery has not recharged, (so you still cannot restart your engine with the contact even after driving) two options, either your battery is dead, or it’s the alternator. Its role is to recharge it while driving. This means that your battery may be in good condition, but it has simply not been recharged by the costly alternator.


If despite all this you are unable to identify the failure, it is still recommended to see a professional who can make a diagnosis to be more reliable. Bear in mind everything that has been mentioned in order to provide him with information that could make it possible for him/her to repair your Lexus RX.
