You’ll want to skip the 2017 Lexus LX 570 above all others, as it’s plagued by severe oil leaks, brake failures, and electronic malfunctions that’ve earned it a dismal 1.0/5 reliability rating. The 2000, 2003, 2005, and 2019 models also consistently appear on problem lists due to transmission issues and dated components. In contrast, the 1996-1999 and 2004-2010 generations offer trouble-free ownership. Understanding these patterns and the specific failures that’ll impact your wallet will help you make a smarter purchasing decision.
Model Years With the Most Reliability Problems
While the Lexus LX 570 enjoys a strong reputation for durability, certain model years stand out as notable exceptions that buyers should approach with caution. The 2017 model ranks as the worst year, plagued by severe engine oil leaks that can destroy the motor, brake system failures, and electronic computer malfunctions costing up to $25,000 to replace. You’ll also want to avoid the 2000, 2003, 2005, and 2019 models, which consistently appear on lists of Lexus reliability issues across multiple sources. Owner experiences from these problematic years contrast sharply with praise for the 1996-1999 and 2004-2010 generations, which delivered trouble-free ownership. The early 2000s models suffer from dated components and inconsistent build quality that undermine the LX’s typically stellar reputation. Similar to the RX 450h’s 2016 and 2017 troubles with faulty fuel pumps and powertrain leaks, certain LX 570 years demonstrate that even luxury brands can have problematic periods. Proper maintenance and checking for software updates, service records, and outstanding recalls are crucial for mitigating many known risks in these problematic model years. These problematic years may require high maintenance costs that fail to deliver meaningful value for the price paid.
Common Mechanical and Electrical Failures Across Problem Years
Beyond the broader reliability concerns, specific mechanical and electrical failures define the problematic LX 570 model years and reveal patterns that potential buyers can’t afford to ignore.
Oil leak problems plague the 2017 model year most severely, risking catastrophic engine damage and triggering dashboard warnings. Early 2000s models faced similar oil circulation issues causing premature wear.
Transmission failures manifest as delayed shifting, harsh engagement, and slippage, particularly after high mileage. Transfer case and differential leaks compound drivetrain vulnerabilities in mid-2000s versions.
Electrical gremlins strike hardest in 2017 models, with documented computer system failures costing up to $25,000. Climate-controlled seats malfunction, Bluetooth connectivity produces static, and the post-2016 joystick interface proves unreliable. False brake warnings further compromise safety. The remote start feature may fail to function properly during periods of low temperature.
Suspension degradation affects models exceeding 100,000 km, creating bouncy rides and costly hydraulic component replacements.
Safety Risks in Specific LX 570 Models
Despite Lexus’s reputation for reliability, specific LX 570 model years harbor serious safety defects that directly threaten occupant protection. The 2008-2019 models face a critical airbag malfunction involving faulty seat belt tension sensors. When these sensors fail, they deactivate the front passenger airbag, knee airbag, and side airbag—leaving adult occupants vulnerable during crashes. This passenger safety issue affects approximately 89,700 vehicles under NHTSA Recall 18V-887. The defect increases injury severity since protective cushioning won’t deploy when needed most. You’ll find dealers offering free seat belt assembly repairs to restore full airbag functionality. Under the Highway Safety Act of 1970, vehicle manufacturers must repair recalls free of charge, and dealerships cannot legally refuse these repairs. If you own an affected LX 570, verify your VIN with Lexus customer service immediately. Don’t ignore this recall—deactivated airbags compromise the restraint system designed to protect you. Similar to how the Mazda 2’s 2014 model year experienced persistent electrical system faults including sensor failures, even luxury vehicles can suffer from sensor-related defects that compromise critical safety systems. Like Toyota Highlander models that experienced engine issues and transmission problems in certain years, the LX 570 shows that even premium brands can have reliability concerns requiring careful model year selection.
Performance and Design Shortcomings to Consider
Beyond safety concerns, the LX 570 confronts buyers with mechanical and design limitations that affect daily driving and long-term ownership costs. You’ll face suspension issues as front control arms wear prematurely under heavy use, requiring costly replacements. The 5.7-liter V8 burns up to a quart of oil every 2000 miles—manufacturers consider this normal, but it demands constant monitoring. Gearbox performance varies considerably; 2008-2015 models struggle with six-speed transmissions, while eight-speed versions offer modest improvements. Brakes overheat frequently, necessitating regular replacements that strain your budget. Water pumps fail prematurely, and transmission problems manifest through vibrations and grinding sounds from loose U-joints. The 2017 model particularly suffers from oil leaks that risk catastrophic engine damage without immediate attention. Similar to its RX 350 sibling, the LX 570 experiences dashboard cracking that affects interior aesthetics and resale value. Poorly repaired body sections often develop corrosion issues that compromise structural integrity and resale value.
Financial Impact of Owning a Problematic Model Year
Owning a problematic LX 570 model year transforms what should be a premium luxury investment into a financial burden that compounds over time. You’ll face maintenance costs that can exceed $25,000 for brake system failures alone, while engine issues may require complete replacement. The 2017 model’s poor value rating of 1.0 out of 5 reflects how reliability problems devastate resale value, making it nearly impossible to recoup your investment.
Beyond repairs, you’re exposed to premium parts pricing, extended warranty purchases, and higher insurance premiums. Many expensive failures occur after factory warranty expiration, leaving you fully responsible. Technical bulletins replace recalls, limiting coverage options. Rapid depreciation forces significant price reductions when selling, while lenders offer less favorable financing terms for models with documented issues. The poor fuel economy averaging 14.5 mpg adds ongoing operational costs that further strain your budget throughout ownership.
