The 2019-2020 Audi Q8 55 TFSI mild-hybrid models can experience a 48V belt-driven starter-generator (BSG) fault that causes sudden loss of motive power, engine stalling, or an 'Electrical System: Fault' warning. This can lead to limp-home mode, an inability to restart, and in some cases the engine cutting out while driving. Owners may notice the start/stop system malfunctioning before the full failure occurs. This issue has also been reported in 2020-2021 model years through service campaigns.
The V35A-FTS 3.4L twin-turbo V6 in 2022-2024 Lexus LX 600 models can contain manufacturing debris that restricts oil flow and leads to connecting-rod bearing failure. Symptoms include engine knocking, low oil pressure, and possible complete engine seizure, with the remedy being full engine replacement. The recall repair is free under NHTSA campaigns 24V381000 for 2022-2023 and 25V767000 for 2024, but an out-of-pocket replacement before coverage typically exceeds $20,000-$30,000. Buyers should verify with the actual repair order that the replacement was completed.
The 2023 LX 600 has the highest owner-complaint volume in NHTSA's data for this generation and carries five NHTSA campaigns, according to the buyer's guide. This broad reliability concern does not isolate a single defect, but it signals a higher chance of unscheduled repairs or repeated warranty visits across multiple systems. No specific repair cost is given; the cost depends on the underlying issue, so buyers should confirm all completed recall and repair work, especially the engine-replacement campaign.
