5known failure points
70NHTSA owner complaints
8safety recalls
$5,500worst-case single repair
A three-row luxury SUV that's genuinely reliable by segment standards, with a well-known VCM/oil-consumption headache and a taillight recall that never seems to fully go away.
Every documented failure, earliest first
Ordered by the mileage the problem typically appears. VERY HIGH
confidence means it's tied to a documented NHTSA recall, and 1 of these are rated Critical.
0k–15k mi● Watch$0–$400VERY HIGH
Tailgate/taillight moisture intrusion causing shorts (subject of two separate recalls)
How to catch it: Confirm both taillight recalls (moisture intrusion) have been completed via VIN lookup before buying — it's a free fix Honda still owes many cars.
Source: documented (NHTSA recall)
40k–80k mi● Plan$0–$1,500MODERATE
VCM (Variable Cylinder Management) related oil consumption and rough cylinder-deactivation transitions
How to catch it: Run a strict oil-consumption test yourself (check level every 1k miles for a month) before the warranty window closes, and keep every oil change receipt.

60k–100k mi● Critical$3,500–$5,500MODERATE
9-speed ZF-based automatic transmission harsh shifting, hesitation, or failure to engage from park/reverse
How to catch it: Have the transmission fluid changed proactively every 30-40k miles instead of Acura's 'lifetime fluid' claim — this is the single best preventive move on this car.
Source: multi-source pattern (AI synthesis)
70k–120k mi● Plan$800–$2,200MODERATE
Rear differential/PTU (power transfer unit) wear on SH-AWD models, especially if fluid was never serviced
How to catch it: Service the rear diff and PTU fluid every 30k miles — most owners never touch it and pay for it later.
Source: owner-reported (8 NHTSA complaints)
80k–130k mi● Watch$400–$1,200MODERATE
TPMS sensor failures, timing chain tensioner rattle on cold start, and worn front control arm bushings
How to catch it: Listen for a cold-start rattle for 2-3 seconds on startup — if present, get the tensioner inspected before it worsens into chain slap.
