Why does the check engine light in my RX400h turn on when I start my car?

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your RX400h firing up its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Why does my Lexus engine sound different?

Strange under-the-hood noises can point to problems within your Lexus RX400h engine. Tapping or knocking could mean you need an oil change. Whistling could mean a belt is misaligned or there's an intake leak. Squealing can be traced back to a loose fan belt, and grinding might be coming from the brakes, not the engine.

What could damage my Lexus RX400h engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, flooring the gas pedal while the car is in Park, or accelerating too quickly, too soon. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.

Can I add water to my Lexus RX400h radiator?

An emergency is the only time you should consider putting water in your radiator. Outside of that, it’s recommended you use a pre-mixed coolant or a 50/50 blend of water and coolant. However, if you need to continue driving your RX400h when you’re out of coolant, having water in the coolant reservoir is better than nothing.

What could cause my RX400h engine to suddenly stop?
