I drive a 2017 Honda Pilot Touring 9-speed and I’ve been dealing with some frustrating issues for last 3 years. The car has sudden loss of power, jerking, harsh shifting, and acceleration problems. I’ve done all the dealer-recommended maintenance (timing belt + water pump, spark plugs, valve adjustment, fuel injector cleaning, regular oil and transmission fluid changes), but the problem still hasn’t gone away. I feel unsafe to drive the car on freeway due to sudden loss of power and then sudden acceleration. Sometimes it feels like the gears don’t shift when they should, I am not a mechanic and not sure if it’s an engine issue or a transmission issue. I checked for recalls but didn’t find any. First I thought it has to do with driving on ECO mode but it seems like it does not matter which mode I drive. It still gives me the same issue.

There is a significant power loss while driving and power up all of a sudden!! This is a major safety concern. Last time nearly missed the hit by behind vehicle due to sudden power loss. today I was taking left turn and suddenly accelerated and it went out of my control. I think it’s due to a fuel pump issue. And from last month in the dashboard “EMISSION SYSTEM PROBLEM “ light pop up twice. First time took to service in Aberdeen SD at Harr motors service center and he adjusted the program I guess. Please take an immediate action regarding this. Thanks, [XXX] Cell [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
