Li Auto Li MEGA Reliability & Ownership Guide: What Cautious Buyers Must Know

Early production Li MEGAs may exhibit electrical glitches, particularly in the battery management system and infotainment screen freezes. Look for consistent OTA update history—well-maintained units with a clear software version trail suggest better reliability. Check for any reports of battery degradation or thermal management anomalies; a healthy kWh retention after multiple charge cycles is a positive sign. Also, inspect the power liftgate mechanism and sliding doors for smooth operation, as these are common wear points on MPVs.

Li Auto positions its dealers to provide high-contact ownership, but support infrastructure outside major markets is thin. Expect routine checks on the battery coolant system, drive unit inspection, and regular software diagnostics. The EV drivetrain reduces moving parts, but the complex air suspension (if fitted) and brake-by-wire system may require specialized attention. Tire wear can be higher due to the vehicle's weight. Brake pad life is generally long thanks to regen, but caliper corrosion in humid climates is a known issue. Plan for annual service visits; parts availability for non-cosmetic items can be slow outside direct dealer networks.

Li Auto typically offers a manufacturer warranty that covers the battery and drivetrain for an extended period, though the specific duration varies by market. Verify whether the warranty is transferable to a second owner—some policies are non-transferable, which severely impacts resale value. After-sales support in regions without official dealerships relies on third-party EV specialists, which may not have access to proprietary diagnostic tools. Always confirm that the vehicle has a valid warranty service book stamped by an authorized center. Battery warranty claims often require proof of proper charging habits; avoid units with incomplete charging logs.

The cabin materials hold up well in daily use, but the panoramic roof can lead to interior heat buildup in sunny climates. The infotainment system is responsive but may experience occasional lag after multiple OTA updates. ADAS calibration is generally reliable, but the camera sensors require periodic cleaning. The keyless entry and facial recognition features can be temperamental in extreme temperatures. Plan for software updates to sometimes change UI layouts unexpectedly. The voice assistant understands common commands but struggles with heavy accents. Over-the-air updates are frequent, which is positive for feature improvements but carries a small risk of introducing new bugs.

Check the charge port door for alignment and sealing—misalignment can cause errors. Examine the third-row seats for fabric wear and latch mechanism sturdiness. Test the massaging function of the front seats if equipped; some early units have motor noise issues. Drive over speed bumps to listen for suspension knocks from the air struts. Inspect the battery underside for any scuffs or impact marks from road debris. Verify that the heat pump operates quietly; a hissing noise may indicate a refrigerant leak. Always request a full diagnostic report from a dealer that includes high-voltage system health and cycling history.
