2018 Lexus Ls Recalls, Issues & Maintenance
The 2018 Lexus Ls carries 2 open NHTSA recalls — most recently covering sidewall and front passenger. No recurring owner-reported issue clusters are on file. Lexus follows Toyota's service rhythm: oil and filter every 10,000 miles or 12 months with 0W-20 synthetic, plus an interim 5,000-mile visit for tire rotation and inspection. Hybrid models (UX 250h, NX 350h, RX 350h/450h+) add long-interval hybrid-specific items — inverter coolant and hybrid-battery cooling-duct checks — while shedding brake wear thanks to regeneration. Modern Lexus engines are chain-driven; there is no timing-belt service on these models.

Campaign #19V134000 · Feb 27, 2019
Issue: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018 Lexus LS vehicles equipped with run-flat tires with a sidewall reinforcement layer inside the tire. The tire-on-wheel assembly process may have caused the reinforcement layer to crack, possibly resulting in the tire tread layer separating from the tire.
Risk: If the tire tread layer separates from the vehicle, vehicle handling and stability may be affected, increasing the risk of crash.
Fix: Toyota will notify owners, and Lexus dealers will replace the affected tires, free of charge. The recall began April 26, 2019. Owners may contact Lexus customer service at 1-800-255-3987. The Toyota number for this recall is KLC.

Issue: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018-2021 Lexus LS500 and 2018-2020 Lexus LS500 Hybrid vehicles equipped with the "Executive Package." The front passenger seat may have been assembled with interference between internal parts that can cause the Occupant Classification System (OCS) sensor to incorrectly detect the occupant. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."
Risk: Incorrect detection of an occupant may result in improper air bag deployment during a crash, increasing the risk of injury.
Fix: Dealers will inspect and repair the front passenger seat, as necessary, free of charge. Owner notification letters were mailed June 7, 2024. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 24LA03.

Essential maintenance
Critical for safety and preventing major damage
Oil & Filter Change
Every 10,000 miReplace every 10,000 miles or 12 months with 0W-20 full synthetic. Severe service (repeated short trips, extensive idling, dirt roads): 5,000 miles per the Lexus guide.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Tire Rotation (5,000-Mile Visit)
Every 5,000 miRotate every 5,000 miles — the interim Lexus service visit. Heavy hybrid SUVs are hard on front tires despite gentle brake wear.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Brake Inspection
Every 5,000 miInspect at each 5,000-mile visit. Hybrids: pads can last 60,000+ miles from regen braking, but rotors corrode from disuse — inspection catches surface rust before it pits.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Brake Fluid
Every 30,000 miReplace roughly every 3 years / 30,000 miles. Hybrid brake actuators are expensive — clean fluid is cheap protection.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Important maintenance
Keeps your vehicle running smoothly and efficiently
Engine Air Filter
Every 30,000 miReplace every 30,000 miles; inspect at 15,000 in dusty conditions.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Spark Plugs
Every 120,000 miIridium plugs at 120,000 miles per the Toyota/Lexus schedule — among the longest plug intervals in the industry.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Transmission / Hybrid Transaxle Fluid
Every 60,000 miLabeled lifetime fill (Toyota WS), but Lexus specialists commonly recommend a drain-and-fill around 60,000 miles — including the hybrid transaxle, whose fluid cools the motor-generators. Toyota WS fluid only.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Recommended maintenance
Extends the life of your vehicle and improves comfort
Cabin Air Filter
Every 15,000 miReplace every 15,000 miles. Behind the glovebox on UX, NX, RX, and IS — one of the easiest DIY jobs on the car.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
Engine + Inverter Coolant
Every 100,000 miToyota Super Long Life coolant: first change at 100,000 miles, then every 50,000. Hybrids have a second, separate inverter coolant loop on the same schedule — make sure a shop services both.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
12V Battery
Every 25,000 miTest annually after year 3. Hybrid 12V batteries are small AGM units that die quietly — the car won't 'ready' even with a healthy hybrid battery. Hybrid-battery cooling ducts (under/behind rear seats) should be checked for dust at service.
Estimated cost — typical U.S. ranges
Dealer
~$225–$390
Shop
~$160–$280
DIY
~$130–$250
Most auto-parts stores test and install batteries free with purchase. Skip the dealer markup.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number
