2015 Honda Accord engine problems

“this has actually been a problem since I first got the car in 2015 but probably started happening in 2016. but it happens so intermittently that I hardly thought about it or figured it just needed a new battery. but I changed the battery and it is still happening where the car won't start. I have to push the button repeatedly or put the car in N to get it to start. eventually it works but I'm worried about an electrical issue causing a fire. when it doesn't start all the lights on the dashboard light up. I keep trying and eventually it works. as I said, I'm afraid it will cause a fire. I called honda and they said some cars were recalled for starter issues but not my vin number. seems like if other Hondas had issues mine would too.”

“I bought a car from a private seller on Craigslist. I've only driven the car for 2k miles before the check engine light came. Before that I had to spend like 1k on the breaks oilchange etc to get the car upto date. Now it feels really unsafe to be in especially for my daughter who is [XXX]. The dmv suspected odometer fraud.”

“On June 17, 2025, I went with my mechanic to inspect a car I was considering purchasing. The vehicle is a 2015 Honda Accord Sport, showing approximately 60,000 miles on the odometer. My mechanic performed a diagnostic scan, and everything appeared to be in good working order at the time. However, on June 23, 2025, I went to the DMV to register the vehicle, and I was informed that the car has a fraudulent odometer reading. The DMV has opened an investigation, but I won’t receive the results for a few months. I am now concerned that the car may not be safe to drive. It emits a burnt plastic smell after being driven and turned off, which raises serious safety concerns. I paid $10,700 for the vehicle and an additional $311 to register it and obtain a temporary plate.”

“I purchased a car from AutoNation Toyota Hayward in Hayward California on June 21, 2025. And on June 24,2025, the check engine light appeared. A mechanic checked my car for the code and informed me that the catalytic converter is faulty. The dealership had informed me that they check the car prior to be sold. As it goes through multiple checks. However, the car that was sold was faulty. They refused to answer my questions as to why a faulty car was sold. As I was driving the car back to the dealership, I could smell the fumes throughout my car.”
