MY 2O18 NIRO HEV, 2nd oil change at 10,000 miles. Noticed oil level over filled on dipstick and smells like fuel. Dealership did not validate my concern. Any one else notice this issue? Any advice?
Thanks for the post, I'm sure I'm not alone in wanting to hear how this works out for you.I had this problem several months ago. Took it in to the dealership for an oil change and they said the oil smelled of gasoline. They changed the oil and asked me to drive it around for awhile, then bring it back so that they could see if the problem persisted. When I brought it back, they told me there wasn’t any gas smell in the oil.
Made an appointment a couple weeks ago due to a recall and very low gas mileage (29-32mpg; I have only been getting max of 32-37mpg since I bought my Niro). A few days before my appointment, the car gave me a warning that there was a “engine control system” problem and that I needed to schedule service. The dealership just finished replacing all my fuel injectors today (they said they were 99% sure this was the issue of both my low gas mileage and fuel getting into the oil).
When I turned on my Niro to leave the dealership, the “engine control system” warning occurred, and they took back my car. They’re going to check it again tomorrow and see if there’s another issue. Very long story short, I feel your frustration.
The primary purpose of detergents in gasoline is to clean intake valves and fuel lines in older cars. Neither of that applies to the direct injected Niro with pressurized fuel tank. We also have a lot of anecdotal evidence now with high mileage Ioniqs and Niros that suggest top tier gas is not needed. There have been some "faulty" injectors replaced under warranty but no evidence this was due to gummed up injectors. I think paying extra for top tier gas is money down the drain, especially when often other stations are receiving the same exact gas. No harm done of course other than your wallet.
Not sure what the Niro uses, but most gas engines have a thermostat that regulates coolant circulation, and it doesn't begin to open until about 180 F and it's not fully open until about 200 F. From that perspective, even on a 100 degree day, the first few minutes that your engine is running, it's "cold" because it's below normal operating temperature.I hope you’re right, and my vehicle just needed to warm up. I live in a very temperate climate, it was about 55-58 degrees out yesterday. Do you know if this would be considered cold for a hybrid?
It is colder and less efficient than 80 degrees for any kind of car! My Niro gets substantially better mpg at 80 degrees ambient versus sub 50 degrees.I hope you’re right, and my vehicle just needed to warm up.
