6known failure points
1842NHTSA owner complaints

$4,500worst-case single repair

A great commuter car wearing a check-engine light — buy the 1.5T carefully or just get the 2.0T and stop worrying.

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 2 of these are rated Critical.

0k–15k mi● Critical$0–$900HIGH
In-tank fuel pump failure (NHTSA recall) — pump can crack and cause stalling at speed
How to catch it: Check the VIN against Honda recall database immediately and get the fuel pump replaced free before it strands you on the highway.
Source: owner-reported (132 NHTSA complaints)
20k–60k mi● Watch$0–$500HIGH
1.5T fuel dilution into engine oil, especially in cold climates and short trips — thins oil and accelerates wear
How to catch it: Change oil every 5,000 miles regardless of the maintenance minder, and let the car fully warm up before short trips in winter.
Source: owner-reported (239 NHTSA complaints)
40k–80k mi● Watch$0–$300VERY HIGH
Infotainment/instrument cluster glitches tied to the body control module software recall causing false warning lights (ACC, collision mitigation, steering)
How to catch it: Confirm the software recall was performed at a Honda dealer — it's a free reflash that eliminates most of the phantom dashboard warning complaints.
Source: documented (NHTSA recall)
60k–100k mi● Critical$2,500–$4,500MODERATE
1.5T head gasket failure / coolant leaking into cylinder (multiple documented owner cases, sometimes with no warning)
How to catch it: Watch for white exhaust smoke, sweet coolant smell, or coolant level dropping with no visible leak — get a coolant/oil cross-contamination test at every oil change on a used 1.5T.
Source: multi-source pattern (AI synthesis)
70k–110k mi● Plan$200–$3,800MODERATE
CVT shudder/hesitation under load (non-turbo 1.5T CVT models) as fluid degrades
How to catch it: Do a CVT fluid change every 30-40k miles with genuine Honda CVT fluid — ignore the 'lifetime fluid' myth.
Source: multi-source pattern (AI synthesis)
80k–120k mi● Watch$300–$600MODERATE
Front brake rotor warping/premature wear, a chronic Accord complaint area
How to catch it: Upgrade to aftermarket slotted rotors or at minimum avoid cheap pads that accelerate rotor wear.
