Compare Lexus ticking or rattling noise repair quotes from specialist garages

Lexus is known for making luxury vehicles designed according to its defining philosophy: "the pursuit of perfection". In the 2023 Auto Trader New Car Awards, it was voted 'Most Reliable Brand' for the fourth time, maintaining its status as a top manufacturer in the UK.

With several cameos in TV shows (notably Breaking Bad, Silent Witness and Modern Family) and mentions in hip-hop songs (Ignition by R. Kelly and Jay-Z's Somewhere in America), this is a brand deeply ingrained in pop culture.

Lexus has also made waves in the world of motorsport, becoming the first manufacturer to enter a production hybrid car - the Rx 400h - in the Nurburgring 24-hour race.

Ticking and rattling are two closely related noises you might hear from your car. If you listen closely to where the sound is coming from and when it happens (while accelerating, for instance), you might be able to work out the cause.

The first thing to check is whether the engine oil is low, requiring a top-up - this is the best-case scenario. If your car is rattling and the sound is coming from the engine, it could be caused by a loose serpentine belt or timing chain. From the car's rear, it might be a loose exhaust or a broken catalytic converter, and the other possibility is worn suspension, which can cause rattling from the front or rear of the vehicle.

Possible explanations for ticking include worn spark plugs, knocking engine rods, dirty valve lifters and misaligned valves. You can learn more about these issues here.

Ticking and rattling noises should be taken seriously as they sometimes indicate a problem with the engine that could cause further damage if ignored.
