6known failure points
348NHTSA owner complaints
5safety recalls
$4,500worst-case single repair
A genuinely great mid-size sedan chassis undermined by a troubled 1.5T engine and jumpy driver-assist software — buy the 2.0T if you can, tread carefully on the 1.5T.
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 3 of these are rated Critical.
0k–15k mi● CriticalvariesVERY HIGH
Front passenger occupant classification sensor / airbag recall (humidity-related false deployment)
How to catch it: Check VIN on NHTSA recall lookup immediately and get the sensor replaced before any long humid-climate ownership.
Source: documented (NHTSA recall)
20k–60k mi● Watch$0–$150VERY HIGH
1.5T engine oil dilution with gasoline in short-trip/cold-climate driving, leading to fuel smell in oil and accelerated wear
How to catch it: Change oil every 5,000 miles regardless of the maintenance minder, and let the car fully warm up on short trips to burn off diluted fuel.
Source: documented (NHTSA recall)
30k–90k mi● Watch$0–$600HIGH
Forward collision warning/AEB phantom braking events
How to catch it: Keep the front camera/radar area clean and free of aftermarket bumper stickers or wraps that can confuse the sensor.
Source: owner-reported (54 NHTSA complaints)
40k–80k mi● Watch$0–$400VERY HIGH
10-speed automatic occasional harsh/hesitant shifts (software-related, some units need valve body or TCM update)
How to catch it: If you feel shift flare or hunting, get the latest TCM software update at a dealer before assuming mechanical failure.
Source: documented (NHTSA recall)
60k–100k mi● Critical$2,000–$4,500MODERATE
1.5T head gasket failure / coolant intrusion into cylinders (documented cluster of complaints, no formal recall yet)
How to catch it: Watch for white exhaust smoke, rough idle, or coolant loss with no visible leak — get a compression/coolant test at any hint and push Honda for goodwill coverage citing the known TSB pattern.
Source: multi-source pattern (AI synthesis)
60k–120k mi● Critical$0–$1,200VERY HIGH
High-pressure fuel pump failure causing stalling/limp mode (subject of the 2019-2020 HPFP recall)
How to catch it: Confirm recall completion status via VIN lookup before buying — this is a safety-critical stall issue, not cosmetic.
Source: documented (NHTSA recall)
