Why does my RX350’s check engine light come on when I start it?

It's okay if your check engine light comes on when you first start your vehicle. It’s just your RX350 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?

Unusual noises can signal a problem with your Lexus RX350 engine. Tapping or knocking could mean you're low on oil. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

What could damage my Lexus RX350 engine?

Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, revving your engine while the vehicle is in Park, or slamming the gas pedal while the engine is still cold. Steer clear of these habits to help protect engine performance and efficiency.

Can I put water in my Lexus RX350 radiator?

It’s not recommended you put water in your RX350 radiator unless it’s an emergency. Under normal circumstances, use a 50/50 mix of water and coolant or a pre-mixed coolant. But, if you need to keep driving while out of coolant, using water is better than driving with an empty coolant reservoir.

What could cause my RX350 engine to suddenly stop?

Reasons your RX350 car engine may suddenly stop include engine overheating, electrical troubles, mechanical issues, ignition system problems, faulty sensors, and low fuel.
