The engine failed catastrophically. White smoke out of the exhaust at 145,000 miles. Dealer checked out the car and they initially though it was a head gasket failure. After taking the engine head off, it turns out it was a 'structural defect' (verbatim words from the mechanic), which was a divot in the engine block. The head gasket was in great shape. Therefore, I needed a 'new' used engine (at $9K) instead of a head gasket replacement (at $4K). A search on the internet shows that forums (driveaccord.net, facebook groups) shows that many Honda Accord owners have similar head gasket failures. I contacted Honda USA and they said there's no recall so I won't get reimbursed.

The Collision Avoidance system activated twice for no reason. Inspection is available. I and my passenger were jerked by the rapid stop & could have been rear ended if anyone was behind me. The second event was in an intersection when I and the driver behind me were driving slowly. if the car behind wasn't alert, he or she could have collided with me. No one was travelling in front of me and yet the brake suddenly engaged. The dealership rep. did not confirm the problem after driving it 5 minutes. There were no warning lamps, messages, or symptoms before the brake engaged in both instances.

Overnight while parked in the garage, the front windshield became cracked without signs of impact. The next night before I had even had the chance to bring it in for a scheduled inspection at the dealership, the crack spidered out to cover almost 15-20% of the windshield. When I took it into for inspection at the dealership, they also mentioned that it looked like there was no impact and the crack was internal to the glass. They agreed that it looked like the same situation as described in Honda TSB 20-118, but said that it could not be covered because it wasnt in the identified VIN range even though it looked like a similar situation described in the TSB.
