The 2016-2020 Lexus IS combines style, luxury, and dependability, with its blend of sharp handling, upscale interior, and a strong reputation for reliability. However, like any vehicle, the Lexus IS has some common issues that prospective buyers and owners should be aware of to ensure optimal performance and longevity. In this article, we’ll take an in-depth look at the typical problems associated with this model, along with advice on what to watch for when buying a used Lexus IS and an overview of ownership costs.
Common Problems with the 2016-2020 Lexus IS
1. Infotainment System Glitches
The 2016-2020 Lexus IS is equipped with a sophisticated infotainment system, but it has received mixed reviews due to its functionality. One of the biggest complaints from owners is the Remote Touch interface, which many find difficult to use due to its touchpad control. Aside from usability, the infotainment system can occasionally freeze, lag, or fail to connect to Bluetooth reliably, especially with newer smartphones.
Symptoms and Prevention: Signs of infotainment issues include unresponsive touchpad controls, difficulties connecting Bluetooth devices, and delays in response times. Lexus issued software updates that address some of these concerns, so make sure the system is updated. During a test drive, thoroughly test the infotainment functions to see if it meets your expectations and is free from operational issues.
2. Dashboard Rattles and Interior Noises
Despite Lexus's reputation for building quiet and refined cabins, some owners of the 2016-2020 IS have reported issues with interior rattles and vibrations, particularly in models with higher mileage. These noises commonly come from the dashboard, door panels, and sunroof area, which can be bothersome and detract from the premium feel of the car.
Symptoms and Prevention: Interior rattles often become noticeable when driving on rough or uneven surfaces. Inspect the vehicle for loose trim or panels, and listen carefully during the test drive. Lexus dealerships and some independent specialists can address this through tightening or padding fixes, but it may require some persistence to eliminate all rattles.
3. Premature Brake Wear
Many Lexus IS owners report faster-than-expected brake wear, with front brake pads sometimes wearing out as early as 20,000 miles. This issue is often linked to the car’s heavier weight and performance-tuned handling characteristics, which can put extra demand on the braking system, especially if the vehicle is driven in a spirited manner.
Symptoms and Prevention: Look for squeaking or squealing noises from the brakes, a “soft” brake pedal feel, or a dashboard warning light indicating low brake pad life. Regular inspection of brake pads and discs is crucial to catch wear early. While brake wear is normal, drivers looking to keep long-term ownership costs low should be mindful of their driving habits and schedule periodic brake inspections.
4. Transmission Shifting Issues
Some owners of the 2016-2020 Lexus IS have reported issues with rough or delayed shifting, particularly in the IS 200t and IS 300 models with the 8-speed automatic transmission. This transmission is generally smooth but may show signs of hesitation or roughness during acceleration or at lower speeds, often due to the complex transmission software.
Symptoms and Prevention: Hesitation, clunking sounds, or rough shifts during acceleration are key signs of transmission issues. Lexus has released software updates for certain models to improve shift quality. Ensure that the latest transmission software updates have been installed, as they can help smooth out shifting. For potential buyers, a test drive in various conditions can reveal if the transmission functions properly without lag or roughness.
5. Fuel Pump Recall
A notable issue with some Lexus IS models from this period is related to the fuel pump. In 2020, Lexus issued a recall for certain models due to a fuel pump defect that could cause the engine to stall, especially at low speeds. This problem, if left unaddressed, could lead to unexpected stalling and safety concerns.
Symptoms and Prevention: Symptoms of fuel pump issues include engine hesitation, rough idling, or sudden stalling. Prospective buyers should check if any fuel pump recalls apply to the vehicle they’re interested in, as Lexus dealers should have addressed these issues for free.
6. Suspension and Tire Wear
The sporty handling of the Lexus IS also brings potential wear issues with the suspension and tires, especially with models equipped with F-Sport packages. Some owners have reported faster wear on suspension components such as bushings, control arms, and shocks. Additionally, the low-profile tires on F-Sport models tend to wear faster and are more prone to damage on rough roads.
Symptoms and Prevention: Listen for clunking or knocking noises, especially when turning or going over bumps, as this could signal worn suspension components. Uneven tire wear or a “bumpy” ride can also indicate suspension issues. For optimal suspension and tire life, regular alignments and rotating tires every 5,000-7,500 miles can be helpful.
7. Battery Drain Issues
Certain Lexus IS models have experienced faster-than-usual battery drainage. While this can happen in any vehicle, it has been noted that some Lexus IS owners report that the vehicle’s electronics can contribute to battery depletion if the car is left unused for extended periods.
Symptoms and Prevention: Symptoms of battery issues include difficulty starting the car, dimmed dashboard lights, or electronic malfunctions. Checking the battery's health periodically and investing in a high-quality replacement battery can mitigate some of these issues. Lexus IS owners should also turn off any electronic devices and ensure lights are off when leaving the car.
Buying Tips: What to Look for in a 2016-2020 Lexus IS
Check for Recall Work: Given the fuel pump recall, it’s essential to confirm that any open recall work has been completed by the previous owner. You can check this with a Lexus dealership or through Lexus’s recall lookup.
Test the Transmission Thoroughly: Take the car on both city streets and highways to assess the transmission. Look for any delays in shifting or rough gear changes, especially in lower gears.
Listen for Interior Noises: Pay attention to any rattling or vibrations in the cabin. Minor rattles are common, but persistent noise may require further inspection or professional adjustments.
Inspect Brakes and Suspension: Given the tendency for faster brake and suspension wear, inspect the brake pads, discs, and suspension components. Look for any signs of wear or misalignment.
Review Infotainment Functionality: Ensure the infotainment system operates smoothly, particularly the Bluetooth and navigation functions, as these can sometimes be glitchy.
Cost of Ownership: Is the 2016-2020 Lexus IS Expensive to Own?
Fuel Efficiency
The fuel efficiency of the 2016-2020 Lexus IS varies by model. The IS 200t (later renamed IS 300) offers respectable fuel economy for its class, averaging around 26 MPG combined, while the IS 350 has slightly lower mileage due to its larger engine. The hybrid IS models are significantly more fuel-efficient, making them attractive options for those with higher mileage needs.
Maintenance and Repair Costs
Routine maintenance for the Lexus IS is generally affordable compared to European luxury counterparts. Oil changes, filter replacements, and regular tire rotations help maintain performance. However, repairs outside of warranty, such as transmission software updates, suspension work, or infotainment system repairs, can be more costly. Many of these issues can be minimized with regular check-ups and software updates through Lexus service centers.
Insurance and Depreciation
Insurance premiums for the Lexus IS tend to be average for the luxury segment, with the IS 350 and F-Sport models typically carrying higher premiums. Depreciation for the IS is relatively moderate, holding value better than some of its competitors. High-trim models or those with the F-Sport package may retain value slightly better due to their performance features and styling.
Potential Extra Costs
Owners may need to budget for battery replacement, infotainment updates, and potential brake or suspension work if they drive frequently or in challenging road conditions. If you own an F-Sport model, keep in mind that tire replacement and suspension wear could occur more frequently due to the sportier components.
Conclusion
The 2016-2020 Lexus IS is a stylish and well-balanced luxury sedan with a reputation for reliability and performance. While it has some common issues, including infotainment glitches, transmission quirks, and potential interior rattling, many of these are manageable with regular maintenance and inspection. By knowing what to look for and staying on top of essential services, prospective owners can enjoy a premium experience with the Lexus IS, making it a rewarding choice in the compact luxury segment.
