How to Replace Lexus Headlights

Lexus headlight replacement is straightforward on most models due to well-engineered design and accessible construction. Whether replacing standard halogen units or upgrading to LED or adaptive headlights on RX, NX, ES, IS, or LS models, this guide covers the main Lexus range.

Step-by-Step Instructions:

1. Open the bonnet and secure it safely. Locate the rear of the headlight assembly from within the engine bay. On RX and NX SUV models, the higher bonnet line provides excellent clearance for accessing headlight mountings. On ES and IS sedan models, access is straightforward with uncluttered engine bays thanks to transverse and longitudinal layouts respectively. LS models offer premium build quality with clearly labeled components. Lexus engineering ensures logical component placement for serviceability.
2. Disconnect all electrical connectors. Lexus headlights typically have 3-5 electrical connectors depending on specification. These include main beam, dipped beam, side light, DRL (daytime running light), and on adaptive models additional connectors for leveling motors and adaptive driving beam systems. Press the release tabs carefully and pull straight out. Lexus connectors feature robust designs with positive locking mechanisms. Take photos of connector positions before disconnecting to ensure correct reconnection. On hybrid models, ensure the vehicle is off to avoid any electrical issues.
3. Remove the headlight mounting bolts. Most Lexus models use 10mm bolts to secure the headlight assembly, though some newer models use Torx screws. On RX and NX models, there are typically 3-4 bolts along the top edge accessible once the bonnet is open. On ES models, expect 3 mounting bolts with clear access from above. IS and GS models have similar arrangements with 3-4 bolts per headlight. LS flagship models feature premium construction with precisely engineered mounting points. Remove all mounting bolts completely and keep them organized as losing them can be expensive given Lexus part prices.
4. Release any additional clips or retainers. Some Lexus headlights use supplementary plastic clips at various points for additional security. On RX and NX models, check for clips at the inner corner near the grille. On sedan models like ES and IS, look for clips at the bottom edge. Lexus clips are generally robust and well-designed but can become brittle with age on older models. Work carefully using a trim removal tool rather than forcing clips as replacements can be expensive from main dealers.
5. Carefully remove the headlight assembly. With all bolts and clips released, gently pull the headlight straight forward out of its mounting position. Lexus headlights slide forward on locating pins that ensure correct alignment. Support the weight as you pull to prevent dropping as headlights are heavier than expected, especially on models with adaptive systems. If you feel resistance, stop and check for missed fixings rather than forcing. Lexus build quality means parts fit precisely, so excessive force is never required.
6. Transfer components to new headlight if needed. If your replacement doesn't include bulbs, leveling motors, or ballasts for HID systems, carefully transfer these from the old unit. When handling bulbs, wear clean gloves to avoid touching glass surfaces with bare hands as oils cause premature failure. This is especially important on Lexus vehicles where owners expect longevity. On adaptive headlight systems, ensure all servo motors and wiring are transferred correctly as these systems are complex and expensive.
7. Install the new headlight assembly. Reverse the removal process by aligning the new headlight with mounting pins and locating tabs. Push firmly into place ensuring all locating pins engage correctly. Lexus engineering ensures headlights fit precisely without adjustment when mounted correctly. Refit all mounting bolts and tighten securely but avoid overtightening which can crack mounting tabs. Reconnect all electrical connections ensuring each clicks firmly. Test all lighting functions before final assembly including dipped beam, main beam, side lights, indicators, and DRLs to confirm proper operation. On adaptive systems, start the engine and turn the steering wheel to verify adaptive function works correctly.

Important Notes: Lexus headlight replacement is generally straightforward thanks to excellent engineering and build quality. When handling new headlights, never touch lens or reflector surfaces as contamination affects light output and Lexus owners expect perfect illumination. On models with adaptive headlights or automatic high beam systems, the headlight may require coding to the ECU to avoid warning lights, which typically requires a Lexus dealer or specialist with diagnostic equipment. Check headlight alignment after fitting using adjustment screws on the rear of the assembly as proper alignment is crucial for optimal visibility and MOT compliance. Lexus headlights are expensive from main dealers, making used genuine parts from breakers an excellent value option.

How to Replace Lexus Front Bumper

Replacing a Lexus front bumper is achievable in 45-90 minutes depending on model. This process covers RX, NX, ES, IS, and LS models, though specific screw locations vary between generations. Lexus build quality means bumpers fit precisely when correctly installed.

Step-by-Step Instructions:

1. Open the bonnet and secure it with the prop rod. Locate the upper bumper mounting fixings along the top edge just below the grille area. Most Lexus models have 4-8 fixings across the top depending on generation and model. On RX and NX SUV models, expect 6-8 fixings across the top due to larger bumper size. On ES, IS, and GS sedan models, typically 4-6 fixings secure the top edge. LS flagship models feature premium construction with precisely engineered mounting points. Remove all upper fixings systematically working from one side to the other.
2. Access the wheel arch areas on both sides. Turn the steering wheel fully to one side to maximize access to the wheel arch liner. Behind each front wheel, locate the plastic arch liner. Remove or release 3-5 plastic clips or screws securing the front section to expose side bumper mounting points. Lexus typically uses push-in clips that release by pressing the center pin first, or Phillips screws on some models. The quality of Lexus clips means they're generally reusable if removed carefully. Repeat on both sides for symmetry.
3. Remove the side mounting screws from both wheel arches. Behind each wheel arch liner, you'll find 2-4 screws or bolts securing each side of the bumper. These are usually 10mm bolts or Phillips screws on Lexus models. Remove all side fixings on both driver and passenger sides. Keep track of which fixings came from which location as they may differ in length. Lexus engineering means fixings are logically placed and clearly visible once arch liners are moved aside.
4. Remove undertray screws and lower bumper fixings. Get underneath the vehicle safely using ramps or jack stands. Locate and remove all screws and clips securing the engine undertray and lower edge of the bumper. Lexus typically uses 8-12 fixings along the bottom edge depending on model. These may be 10mm bolts, Phillips screws, or push-in clips. On RX and NX models, the undertray is substantial for aerodynamics and may have more fixings. You don't always need to remove the entire undertray but may need to lower it for access to bumper fixings.
5. Disconnect fog lights, sensors, and electrical connections. Reach behind the bumper and disconnect all electrical connectors including fog lights if fitted, parking sensor connections if equipped (most Lexus models have parking sensors as standard), camera connections on models with front cameras for parking assist, and any additional connections for adaptive cruise control radar on newer models. Press release tabs carefully and pull straight out. Count how many connections you disconnect to ensure you reconnect them all during refitting. Lexus uses high-quality connectors with positive locking mechanisms.
6. Release the bumper side clips and mounting tabs. Lexus bumpers are secured by plastic clips or metal brackets on each side that slot into the wing panels. With all fixings removed, firmly but gently pull the bumper forward from one corner while supporting the opposite side. You may need to wiggle slightly to release the clips. Listen for clicks as clips disengage. On premium models like LS, bumpers may have additional locating pins for precise fitment. Work carefully as Lexus bumpers are large, especially on SUV models, and can be awkward to handle alone.
7. Remove the bumper completely from the vehicle. With all fixings removed and clips released, carefully pull the bumper straight forward away from the vehicle. Lexus bumpers are reasonably substantial but manageable. RX, NX, and LX SUV bumpers benefit from a second person due to size and weight. Place the removed bumper on a protected surface to avoid scratching the painted surface. Lexus paint quality is excellent and worth protecting.
8. Prepare and fit the replacement bumper assembly. Before installation, transfer any brackets, trim pieces, fog lights, sensors, or components from the old bumper if not fitted to your replacement. Check the condition of all mounting rubbers and clips, replacing if damaged as Lexus expects precise fitment. Align the new bumper with mounting points and push firmly into place ensuring all side clips engage properly with distinctive clicks. Reconnect all electrical connections including fog lights, parking sensors, and cameras ensuring each clicks firmly. Systematically secure with all screws and clips in reverse order. Test all electrical functions before final assembly including fog lights, parking sensors (listen for beeps when close to objects), and cameras if fitted. Check panel gaps are even on both sides for professional appearance. Lexus build quality means gaps should be consistent when correctly fitted.

Top Tips: Lexus bumpers are engineered for precise fitment and maintain tight panel gaps when correctly installed. When refitting parking sensors, ensure each clicks firmly into its mounting hole and is correctly aligned flush with the bumper surface as Lexus owners expect perfect operation. On models with front-mounted cameras or radar for adaptive cruise control and pre-collision systems, these may require recalibration at a Lexus specialist after bumper replacement to ensure safety systems function correctly. Check all panel gaps between bumper and wings are even before final tightening, as Lexus's reputation for quality means inconsistent gaps are immediately noticeable. Lexus bumpers are expensive from main dealers, making used genuine parts from breakers an excellent value option while maintaining OEM quality and fit.

Common Lexus Parts Problems & Solutions

Lexus vehicles are renowned for exceptional reliability and refined luxury. The brand has been named UK's most reliable car manufacturer for 2025 by Warranty Solutions Group with just 5.79% warranty claim rate and £639 average repair cost, earned its sixth Most Reliable Brand title in seven years from Auto Trader New Car Awards, and achieved 97.01% reliability rating in Honest John Satisfaction Index 2025. However, certain components can experience specific issues. Here are the most commonly reported Lexus parts problems based on verified data from UK owners, mechanics, and industry specialists.

Infotainment System Issues (2022+ NX and Newer Models):

• Touchscreen Freezing and PIN Code Demands: The 2022+ Lexus NX and other newer models with updated infotainment systems experience touchscreen freezing or responding slowly, especially in early production vehicles. More problematically, some vehicles randomly demand a PIN code while driving, overriding CarPlay or any other screen function. One owner reported this happening every 15 minutes requiring constant clearing. Dealers attempted fixes 2-3 times before reducing frequency to 2-3 times per year by setting PIN code to 1111. This is particularly dangerous when navigating as the PIN demand interrupts directions.
• CarPlay and Android Auto Connectivity: Wireless CarPlay fails to connect approximately 25% of the time according to owner reports. The workaround requires going into iPhone settings, disabling and re-enabling CarPlay, which fixes the issue without vehicle restart. Alternatively, plugging in a cable forces connection, after which cable can be disconnected. Android Auto occasionally drops connection at inopportune moments during navigation. These issues affect user experience on otherwise highly reliable vehicles.
• Solutions and Costs: Dealer software updates sometimes resolve issues but not always permanently. Repair costs range from £150-£400 for infotainment work. Most issues are covered under warranty. These problems are software-related rather than hardware failures, suggesting future updates may improve reliability. For pre-2022 models with older touchpad systems, the main complaint is slow response rather than complete failures.

Hybrid Battery Cooling Fan Issues (All Hybrid Models):

• Dust and Pet Hair Accumulation: Lexus hybrid vehicles including RX 400h/450h, NX 300h/350h, ES 300h, and others can develop issues with the hybrid battery cooling fan becoming clogged with dust or pet hair. The cooling fan draws air through the cabin to cool the high-voltage battery pack located under rear seats. When the fan intake becomes blocked, it triggers warning lights on the dashboard or reduces hybrid system efficiency. Symptoms include hybrid system warning lights illuminated, reduced fuel economy as system operates less efficiently, and unusual noises from under rear seats as fan struggles.
• Prevention and Solutions: Regular cleaning of the hybrid battery cooling fan intake prevents issues. The intake is typically located under or behind the rear seats with an accessible filter that can be removed and cleaned. Use a vacuum cleaner to remove accumulated debris every 6-12 months depending on usage. If warning lights appear, immediate cleaning usually resolves the issue. Repair costs if dealer service is required range from £150-£400. This is a simple maintenance item that prevents more serious hybrid system problems. Lexus hybrid systems are exceptionally reliable when this basic maintenance is performed.

Early RX 350 Specific Issues (2007-2013 Models):

• Power Steering Fluid Leaks: Early Lexus RX 350 releases experienced steering issues, notably power steering fluid leaks from the rack and pinion system. This is a massive safety hazard and costly to repair. The problem is hard to predict and can affect vehicles with fewer than 100,000 miles. Symptoms include puddles of red fluid under vehicle where parked, heavy steering especially at low speeds, and whining noise when turning. Repair involves replacing the power steering rack at costs ranging from £800-£1,500 including parts and labor. If caught early with minor leaks, resealing may be possible for £300-£500.
• Engine Oil Leaks: A significant issue plaguing early Lexus RX 350 models was oil leaks from the engine, causing maintenance challenges and expensive repairs. In severe cases, oil leaks led to replacement engines. Due to these leaks, many owners paid for engine sealants or repairs. Common leak points include valve cover gaskets, oil pan gaskets, and rear main seal. Repair costs vary from £200-£500 for gasket replacements to £3,000+ for engine replacement in extreme cases. Regular inspection of oil level and checking for leaks underneath prevents catastrophic damage.
• Premature Battery Failures: Premature 12V battery failures are common in RX 350 models, increasing maintenance costs especially if the problem keeps recurring. Symptoms include difficulty starting, electrical accessories malfunctioning, and dashboard warnings. Lexus batteries are expensive from dealers at £200-£300 but quality aftermarket alternatives available for £100-£150. Hybrid models are particularly sensitive to weak 12V batteries as they're required to boot the hybrid system.
• Air Conditioning Problems: Many Lexus RX drivers report problems with air conditioning, often appearing in models from 2007 to 2013 and affecting vehicles with over 26,000 miles. Issues include AC not blowing cold air or failing altogether. Lexus provides updated parts to fix the issue. Repair costs range from £400-£1,200 depending on whether compressor, condenser, or entire system requires replacement. Common failures include AC compressor seizing (£600-£1,200) and refrigerant leaks (£200-£400).

Suspension and Shock Absorber Issues (RX 450h):

• Suspension Wear on Heavy Vehicles: Many drivers have reported problems with suspension and shock absorption, particularly in the Lexus RX 450h which is a hefty vehicle. Signs of shock absorber failure include uneven dipping of the vehicle when braking, less comfortable ride quality over bumps, and excessive body roll in corners. Front suspension noise from worn strut mounts and lower control arm bushings is common on higher-mileage examples. Repair costs range from £400-£700 for front suspension work including strut mounts and bushings. Complete shock absorber replacement costs £600-£1,000 for a pair including labor. Regular inspection prevents safety issues.

Transmission Issues (Various Models):

• CVT and Automatic Transmission Problems: The Lexus RX and other models have been reported to experience various transmission problems including rough or delayed gear changes, transmission fluid leaks from seals, and in rare cases transmission failure leading to expensive repairs. Some owners report transmission slipping or jerking during acceleration or deceleration. Lexus CVT transmissions are generally reliable but can develop issues on higher-mileage examples without proper fluid changes. Repair costs range from £200-£500 for fluid changes and minor repairs to £2,500-£4,000 for transmission rebuild or replacement. Regular transmission fluid changes every 60,000 miles using genuine Lexus fluid prevents most issues.

Electrical System Issues (Various Models):

• Door Lock Actuator Failures: The Lexus RX 350 and other models have encountered door lock actuator failures causing doors to not lock or unlock properly, either manually or with key fob. Warning lights may appear on dashboard. Repair involves replacing failed actuator at £150-£300 per door including labor. This is more of an inconvenience than serious problem but affects premium ownership experience.
• Rain-Sensing Windshield Sensor Faults: Despite its convenience, the rain-sensing windshield feature in Lexus RX 350 models, particularly 2017, faces widespread complaints due to faulty sensors. Many owners report problems with sensor performance, particularly at night, leading to malfunctioning wipers despite adjustments for sensitivity. The problem affects visibility while driving in poor conditions. Repair costs £200-£400 for sensor replacement.

2022 NX Recalls (Second Generation):

• DC-DC Converter Issues (NX 450h+ Plug-In Hybrid): Certain 2021-2022 RAV4 Prime and 2022 Lexus NX 450h+ plug-in hybrid vehicles were recalled because the electric current rectifying module within the DC-DC converter may have been damaged during production, which can result in electrical short-circuit. Owners were advised not to charge vehicles when ambient air temperature is below 41°F (5°C). Dealers replaced the DC-DC converter free of charge under recall. This affected 891 vehicles.
• Electronic Parking Brake Software: The Skid Control ECU within the Brake Actuator Assembly may falsely detect an overcurrent condition and enter failsafe mode preventing electronic parking brake engagement. Dealers reprogrammed the Skid Control ECU free of charge.
• Front Shock Absorber Mounting Welds: Missing spot-welds between body panels and front shock absorber mounting areas may cause front shock absorber to separate from mounting area. Dealers added welds to body panels or replaced body panels where welds failed, free of charge.

Lexus Reliability Assessment:

Industry-Leading Reliability with Minor Issues: Lexus's reliability is unmatched in the luxury segment. Warranty Solutions Group 2025 data shows Lexus owners make the fewest warranty claims at just 5.79% rate with £639 average repair cost, dramatically better than the 28.3% industry average claim rate and £621 average cost. This means Lexus vehicles visit repair shops far less frequently than competitors. Auto Trader New Car Awards named Lexus Most Reliable Brand for the sixth time in seven years based on over 200,000 UK motorists' real-world experiences. What Car? Reliability Survey 2023 gave Lexus 98.3% overall rating with NX achieving incredible 99.8% (first generation) and 99.4% (second generation), making it the most reliable vehicle overall. The Honest John Satisfaction Index 2025 ranked Lexus #1 for reliability at 97.01%, ahead of Tesla (95.29%) and Toyota (94.65%).
