Which GX years have the most problems?
Complaint volume by model year. Raw NHTSA totals, not adjusted for sales volume or time on the road, so older and higher-selling years accumulate more. Every year links to its full breakdown.
Sentiment is sharply divided by generation. The previous-generation GX 460 (model years up to 2023) is overwhelmingly praised for its legendary reliability, proven V8 powertrain, comfortable and durable luxury, and high long-term value. Owner feedback describe
GX 550 (2024+):
Major engine recall (V35A-FTS twin-turbo V6): Safety recall for machining debris causing potential bearing failure and catastrophic engine seizure. Linked to broader issues with Toyota/Lexus's new turbo engines. Frequency: very frequent.
Long-term reliability concerns: Widespread owner and analyst concern about unproven new powertrain and potential for other "mechanical bugs" in the first model year. Frequency: very frequent.
Reported reduction in build quality: Isolated mentions of less soundproofing, cheaper interior materials, and thinner body panels compared to the GX 460. Frequency: isolated.
