Tl* the contact owns a 2015 honda accord. While attempting to use the push to start feature, the vehicle made a grinding sound and failed to start. The vehicle was not diagnosed or repaired. Additionally, the vehicle was involved in a head on crash with an unknown vehicle. The three occupants sustained unknown injuries and were provided medical attention. A police report was filed. The vehicle was towed to an independent mechanic and was informed that the alternator and air bags needed to be replaced.

My car sometimes starts, sometimes doesn't start. Sometimes it starts right away on the first try. Sometimes it takes multiple tries after a few seconds to a few minutes. The times when it doesn't start, I turn the key in the ignition and hear one single tiny click. The dash board lights come on, radio plays, air cond. Works, wipers work headlights work. Eventually, after a few retries, the engine will start. Sometimes it starts after waiting a few minutes. When I do get the car started, it runs perfectly smooth.
