Are you experiencing an unpleasant noise coming from your Lexus? It can be an unnerving experience, leaving you wondering what it might be trying to say. Your car may have a life of its own, and it’s trying to communicate with you through these strange noises. Ignoring these noises can lead to severe damage or expensive Lexus repair, so it’s essential to decode them as soon as possible. So, if you’ve heard any unusual sounds lately, it’s time to take immediate action and give your Lexus the attention it deserves.


Car Sounds Portland

If you’re hearing a ticking sound from your Lexus engine, it’s important to take action soon. Although the noise could be minor, it could also indicate something far more serious brewing under the hood. If left unchecked, this could lead to engine failure, necessitating extensive and costly repairs. There are several reasons why you might be hearing this noise:

  • Low oil levels or pressure– an indication that your engine is not well lubricated. This could be due to worn-out seals or gaskets or a leak somewhere in your engine. If Ignored, it could lead to more severe problems, such as your engine overheating.
  • Bad piston rings and valve seals– something wrong with pushrods, valves, or pistons. If ignored, it could lead to clunking and whining noises.
  • Rod knocking– could be a sign of a damaged bearing on the rod. This can be a worrisome issue, as the ticking noise clearly indicates that the rod is shifting and causing undue stress on the engine.
  • Fuel injectors firing– could be caused by the injector valves rapidly opening and closing to regulate the fuel entering the combustion chamber. It’s always best to consult a mechanic to determine whether or not the fuel injector needs to be addressed.
  • Valve lash– A maladjusted valve train is a common source of ticking noises. A trusted mechanic can inspect to determine if this is the root of the problem.
  • Timing chains– timing chain slack caused by worn guides or tensioners can cause a ticking sound and can cause major engine failure if timing deviation becomes extreme.

No matter what’s causing the ticking, bringing your car in for an assessment as soon as possible is important to prevent further damage.

Knocking or Pinging

If you’ve recently heard a strange knocking sound coming from your Lexus engine, don’t panic. This sound may be caused by engine knocking, generally caused by an improper air-fuel mixture within your car’s engine. This mixture issue can be caused by several problems with your fuel delivery system, which causes combustion timing to become unbalanced. Instead of burning evenly, pockets of concentrated fuel will combust at the wrong time, causing loud pinging or thumping sounds that can be alarming. Before taking your Lexus into a service center, check to see if you’re using the appropriate type of gasoline and inspect your spark plugs and fuel injectors for cleanliness. These easy fixes may be enough to correct the issue and eliminate that frustrating noise.


As you accelerate in your beloved car, a humming noise may emerge. Do not be quick to dismiss it as ordinary engine noise – it could be signaling a more serious problem with your wheel bearings. Though this issue is often ignored or overlooked, you can check your RPM gauge to see if the humming persists. If it does, fear not – you can take steps to combat it. Begin by coasting at high speed, and if that does not do the trick, take a trip to your local mechanic.


When your car starts making unusual noises, it may be difficult to pinpoint the cause. However, if you hear a rattling sound coming from your engine, especially after a cold start, it could be a warning sign of a worn timing chain. While most newer vehicles have a low amount of rattling by design, if the rattling becomes severe or increases in intensity, it could be a sign that your timing chain needs to be replaced. It’s important to address this issue as soon as possible because a worn timing chain can cause major damage to your engine if left unchecked.


Is your car sounding like an unbalanced washing machine? If so, don’t wait any longer to get it checked out. These types of noises can usually be attributed to a loose wheel nut, which can cause significant damage if left unaddressed. Take your car to a certified technician for repairs right away if you suspect there may be something wrong with it.


A high-pitched whining noise indicates something is amiss. If left unattended, it could lead to more extensive damage. If the sound increases as you accelerate, it is likely due to a failing bearing. While bearings are found throughout your engine, including in crucial components like the alternator and water pump, don’t be overwhelmed by this information. Seeking guidance from a professional mechanic is your best bet.


If you hear a grinding noise, this could be a sign of a bigger problem. One common issue is when engine parts rub against each other without proper lubrication due to a low oil level. While most modern cars will alert you if the oil level is low, older Lexus models may not have this feature. To ensure your car’s longevity, checking the oil level regularly is crucial. If you suspect a leak is the culprit, bringing your vehicle to a trained professional as soon as possible is best. Grinding sounds can be caused by a variety of possibilities, from engine component failure, to bearing, brakes and transmission component failure. 

Screeching During Acceleration

Whining Noise When Accelerating Portland

As you drive down the road, there’s a sound that you may hear all too often. It’s a high-pitched noise, almost like nails on a chalkboard. This noise is caused by your car’s belts, specifically the power steering or AC compressor belt. It’s a telltale sign that the belts have worn down and are slipping on the pulley to which they are mounted. Ignoring this noise can lead to disastrous consequences, as the belts can snap altogether, leaving you stranded on the side of the road.
