Engine mount causing vibration and sound under the hood.
Driving very slowly uphill in a hospital parking deck, the principal driver of the car turned into an available parking slot applying some gas, from 25-30 feet away, only to have the vehicle accelerate uncontrollably, even with the driver's right foot fully engaged with the brake pedal. The van jumped over parking blocks at the end of the space and struck a concrete post, whereupon the engine compartment crumpled and the airbags engaged. The van bounced back approximately twenty feet. Witnesses attracted by the sound of squealing tires, revving engine noise (before impact) and the subsequent crash itself came to render assistance and call police. The driver's right's foot was severely bruised by the crash impact and her sternum fractured. The vehicle was a declared total loss.
The engine was making pinging sounds like lifers were bad, but computer didn't show anything wrong and no engine lights came on, took to Honda dealer they said bearings bad and needed new engine. Why would that happen when engine oil was maintained and changed . Never over heated etc.
