gas

Running a 2013 3.8 Genesis with 1500 miles on it and started to feel slight vibration on the brakes as if something is brushing against it. The issue is not consistent hence difficult to reproduce. Took it to the dealer last week they did not find anything wrong. Surprisingly haven't had the...

I think I've seen something similar for the gas pedal lag, but wanted to make sure you guys thought my issue was the same. Sometimes when leaving for work or coming home from work, my 2009 v6 premium tech package will lag when I press the gas pedal until I've driven it for a bit. The RPMs will...

It could be very useful if at least 15-20 regular forum members did some data collection over about a 60-day period, using the following data points: - Car/engine: 3.8/4.6/5.0 non-R-Spec/5.0 R-Spec - Fuel octane used: 87/89/91/92/93 - Miles driven: ( # ) - Miles type: Approximate ratio of...

Genesis is on the list. Here is the link http://www.foxnews.com/leisure/2012/11/02/epa-finds-hyundai-kia-overstated-gas-mileage/?intcmp=features CEH

Hyundai and Kia overstated the gas mileage on most of their models from the past three years in an embarrassing blunder that could bring sanctions from the U.S. government and millions of dollars in payments to car owners. Because of the inflated mileage, discovered during an audit by the...

Hello, I've done some researches here as this is my second time with a Check Engine Light issue since 2009. But I believe this could be different than Gas Cap issue so I decided to ask for advice. Symptoms; 1. It would take more than 5 minutes to fill up since I will manually have to hold on...

Well, my Genny 4.6 now has 17k miles, and i noticed an improvement in the MPG. For example, last year, I drove to Las Vegas and back, round trip about 500 miles, and got 27 MPG. Just made the same trip, and it read 28.5 MPG. Recently, I used a loaner Sonata with the 2.4 L motor. During 5 days...

Hello I am a new Hyundai owner. I have the 5.0 R Spec and was wondering what the recommendation was for gasoline. Thanks for the help.

Hey i have a 2013 genesis coupe 2.0t and it has 3000 miles. So far my gas mileage averages at 17-18 mpg driving around in the suburbs 75% and on the highway 25% When i bought the car i was told that it should get 21 city 31 highway so something has to be off... Also when i start the car or...

I ran out of gas the other day in my Genesis sedan when the computer said I had 48 miles to go, the low fuel light was not on and the gas gauge said that I had 1/16 of a tank left. I have previously gone below 30 miles fuel left and not run out of gas, so something changed. Anyone have any idea?

I figured I'd ask here to see if it's just my vehicle or it is normal for the car. I just purchased a CPO 2011 Genesis 3.8 V6 model. I LOVE the car but one thing I noticed is that it almost seems if the car is decelerating more than normal. If I'd guess, it's almost like the emergency break...

I have been using regular unleaded gas in my Equus (87 octane) and the car has been running fine. Just to compare, the last time I filled up the car I used super at a 93 octane level. I can feel a difference. The car feels like it is accelerating faster. Almost like the car has more lower...

Does anyone know what Gas Additive the dealer adds when servicing the Genesis as recommended in the Service Schedule?

I just finished up a 612 mile round trip from Central Jersey to Boston area, great mileage. My 09 Genesis PP with 47K miles delivered 29 mpg on the way up and 31 mpg on the return trip, average 74 mph. Even after driving this car since 9/08 it still feels new and continues to provide a great...

Had my 2012 3.8 for 3 months now, I noticed the average gas mileage reporting seems at least 0.8 miles higher than my own calculation after filling up the gas. Do you see anything similar? For my suburban New Jersey driving, I constantly get between 20.8 to 21.8MPG. However, it's always 0.7 or...

So what is the census here? What type of gas and how many miles do you get from a tank? Right now in my BMW I fill it with super and I get no more than 300 if I'm lucky..

I have a new 2012 V8, 4.6 Genesis, and would like know what the best gas to use.

First let me say that i plan on going back to the dealer and sitting in another R Spec but i will not be able to do that until monday. I was just wondering if anyone else has experienced any of my issues. The first issue i am having is that my gas mileage seems to be getting worse. I have...
