Lexus is a premium car brand known for its reliability and high quality. Over the years, many have become loyal to the brand, but Lexus models do have some problems, though, just like any other car brand.
Understanding these common problems with Lexus cars can help owners and potential buyers make informed decisions about their vehicles. From Lexus SUV problems to Lexus hybrid problems, knowing what to look for is necessary to maintain these high-end cars.
This article will discuss the top 10 most common issues and problems with Lexus cars. From problems such as Lexus reliability issues and suspension issues to common repairs, we will cover it all.
Is Lexus as Reliable as You Think?
It is well known that Lexus makes safe, reliable cars that get great gas mileage. It was the most reliable luxury brand in 2023, and the RX was tied for the most reliable model. The brand also gets good marks from safety groups. For instance, the 2024 Lexus RC and RZ get the best IIHS grades.
Despite this, no car brand is entirely free from problems. Lexus owners have reported various issues that need to be resolved, and regular service can prevent all the problems you may face.
Top 10 Most Common Issues and Problems with Lexus
Lexus cars are known for being reliable and luxurious, but over time, they can have problems like any other car. Here are the most typical issues you might face with Lexus cars:
- Oil Leaks: Many Lexus owners, especially older models, say their cars leak oil. These leaks can start as early as 8,000 miles into the car’s life, and if they aren’t fixed, they could damage the engine.
- Transmission Issues: Lexus vehicles can experience transmission problems, including shift flares, incorrect shifting, and rattling noises. These issues often manifest in high-mileage vehicles and may be caused by factors such as low transmission fluid or faulty sensors.
- Electrical Problems: Lexus cars can have some electrical problems, such as alternators that don’t work, starts that don’t work, and batteries that die. These issues can make it hard to start the car, cause the headlights to dim, or cause electronic parts to fail.
- Suspension and Steering Concerns: Some Lexus models may experience suspension problems, resulting in uneven tire wear, vehicle pulling to one side, or a bumpy ride. These issues can affect the car’s handling and comfort.
- Air Conditioning Malfunctions: Lexus air conditioners can have issues like not cooling enough, weak airflow, or strange smells. These problems can be caused by refrigerant leaks or clogged cabin air filters.
- Engine Problems: Lexus engine problems could be annoying, such as spark plugs not working, ignition coils not working right, and issues with the variable valve timing (VVT) system. These can make the car run less well and use more gas.
- Brake System Issues: Some Lexus models may experience brake-related problems, such as premature wear or noise during braking. Regular and immediate maintenance is necessary to guarantee the best possible braking performance.
- Water Leaks: Certain Lexus cars, especially those with sunroofs, may leak water. If you don’t fix these right away, they could cause damage to the inside and electricity problems.
- Dashboard and Interior Defects: Some Lexus owners have reported issues with dashboard cracking, particularly in older models. The materials used, heat, and UV rays can be blamed for this problem.
- Sensor and Computer Malfunctions: Lexus cars’ sensors and computer systems are critical. When these parts don’t work right, they can trigger warning lights, lower performance, or cause other problems that need to be diagnosed and fixed by a professional.
What Is the Biggest Problem with Lexus?
While Lexus vehicles are renowned for their reliability, they are not perfect. The most significant problem across Lexus models is oil leakage from the timing chain cover. This issue affects multiple model years, particularly those produced between 2007 and 2015.
This problem is most common in the Lexus RX 350 and ES 350. This oil leakage can trigger low engine oil pressure warnings and cause a persistent clicking noise while driving. If left unaddressed, it can lead to catastrophic engine damage.
Warranty Coverage: What Lexus Owners Need to Know
Lexus provides peace of mind to owners with comprehensive warranty coverage for new vehicles. The Basic Warranty covers repairs and adjustments for 48 months or 80,000 kilometers, whichever comes first, addressing any defects in materials or workmanship of Lexus-supplied components. Additionally, a Powertrain Warranty offers the same 48-month or 80,000-kilometer coverage. For hybrid models, the Hybrid Warranty extends up to 96 months or 160,000 kilometers, ensuring long-term protection for hybrid-specific components.
Also, beyond the basic coverage, Lexus provides extra protection plans for longer-term care, including Vehicle Service Agreements (VSAs) that can be covered after the factory warranty runs out. These plans guarantee security and peace of mind for owners wishing to keep their Lexus protected for longer.
Conclusion
While Lexus is renowned for its reliability, it’s important to be aware of the common issues that can arise. By scheduling regular maintenance, promptly addressing problems like oil leaks and electrical faults, and staying informed about common issues, you can enjoy a smooth and dependable driving experience for many years.
Remember, Lexus cars have their problems, but they are still unique in the luxury market because they are so reliable and well-built. If Lexus owners take good care of their cars, they can be sure that they will be a pleasure to drive for many miles.
