Tl-the contact owns a 2017 Honda Civic, the contact just recently purchased the vehicle used. When the vehicle was started from a cold start after being parked. The check engine light and the abs brake warning light illuminated before the failure. The vehicle was taken to sunwest Honda 1030 north coast highway, newport, or 97365 (541) 265-8547, where the contact was advised that the problem could not be duplicated. The manufacturer was contacted and made aware of the failure. The failure mileage was 5,000. Cb.
The car randomly displays a check emissions system and check transmission systems error on the dashboard while driving. The check engine light comes on and the "d" indicator on the display flashes. When the check transmission systems error displays the car does not shift as it should. I took it to my mechanic and he couldn't find anything wrong with the engine or transmission, and no error codes came up on his computer. I called the dealership and they said a software update is needed. I am concerned about wear and tear on the engine and/or transmission due to these issues.
Sudden acceleration: I have been observing that the vehicle suddenly accelerates while driving downhill or merging on the highway. I have also noticed that it will accelerate when you turn off the cruise control. The speed is uncontrollable for few seconds before the engine starts the deceleration. I have taken a vehicle to the dealer twice and they have assured that this is normal function since check engine light is not on. The vehicle is 1. 5 yrs old and has @15k miles on it.
