I bought a 2014 Honda Accord with 92k in November 2019. I did my first oil change in Feb '20 & it all went downhill from there. The 3rd party I took it too for an oil change informed me that I had almost no oil in my car. I was not going more than 5k miles in between oil changes, didn't even let it get down to 25% oil life. Just before I went back to Herb in Apr for my next oil change, my oil light flashed & I noticed my car was making a rattling noise. I checked & had NO oil in my car yet again, added a qt. So I asked Herb about it & to check for any leaks. They told me my car just burned a lot of oil - 1 quart for every 1k miles-Which seemed absurd to me. I brought it back in June & asked for an oil consumption test. They refused to do the oil consumption test because they found my valve cover gasket was leaking & "that was the problem." They also said if I got the valve adjustment maintenance done it would "fix" the leak in my valve cover. But they wanted $600 to do the valve adj. I took it to my own mechanic & had it all done for less than $300. I went back to Herb for another oil change, & had them check my mechanics work & they told me I was no longer leaking oil. Well, 1600 miles after that oil change I am completely out of oil again. I let it go for a while just to get the pattern down. Without fail, 1600-1900 miles after an oil change I am out of oil. Like, empty. My oil light doesn't even come on anymore. My engine is misfiring SO bad. I wrote Honda recently & they claimed they knew nothing about oil consumption issues in this vehicle. They suggested I bring it to another dealership for a 2nd opinion, since Herb was unable to find the problem. That dealership also told me they "hadn't heard of any oil consumption issues with my vehicle" They told me the 1st step to finding the problem was to do the oil change & oil consumption test. Funny how Herb didn't want to do this. I was still at 60% oil life when I went in, so I will be going back when I am closer to needing an oil change again. But I recently met someone who is a master mechanic & even HE knew about my vehicles engine oil consumption issues, & he actually printed me a service bulletin FROM HONDA STATING my exact vehicle has oil consumption issues & the solution is to "1st do oil consumption test, then replace oil jets, all of the pistons, pins, rings, & spark plugs" Watch out when dealing with these people, they lie right to your face. Oh & do yourself a favor - don't buy a car with the "Earth Dreams Technology Engine" - it's commonly known as one of the worst engines Honda has ever made. Honda won't help me out at all because the vehicle is "out of warranty" & there are no open recalls for this problem. They won't even waive the diagnostic fee for me. They could care less about their customers who bought a USED car. Don't be like me people - do your research when buying a used Honda. Oh and this is coming from someone who has owned Honda's their entire life & used to swear by them, used to tell everyone & their mothers, 'buy a Honda!' - but after being lied too repeatedly I am no longer a Honda fan, & instead of recommending them I will be warning everyone of their shady antics. My car basically needs a new engine, I'm only 2 years into my 5 year loan on this car & I can't drive without my engine misfiring, which is so rough it feels like it's going to die on me any time.
