#882 of 1988 Re: Gas mileage [johnhowelljr] by rdaystrom Aug 25, 2004 (8:58 pm)
Replying to: johnhowelljr (Aug 16, 2004 1:08 pm) John, The Sorento has a very efficient air filter. If you have any doubt whatsoever about the air filter replace it. I did this in mine because it had 36,000 miles of previous owner use and I had experienced horrible mileage. My mpgs went from 8 mpg hwy to 22.5 mpg instantly! A new air filter is about $35 at KIA and worth it because it stops the dirt. It's a super high quality filter.     Also whatch your driving habits. The Kia Sorento has a wonderful V-6 engine that produces it's maximum torque at a lower rpm (around 3000 rpm) than most other similar vehicles. (4100 rpm for the Toyota Highlander) This characteristic is great for driving because the power is available "right now" so to speak without the need for downshifting to get the rpms up as with many competitive models. This characteristic can also lead the driver to become quite "heavy footed" around town and gas mileage can suffer if the engine is pushed hard.(which is very easy to do) The power is addictive. Don't get me wrong...this is a good characteristic. We just have to be conservative if we want to have better mileage) You could also use Mobil One Synthetic oil 0W-40 or OW-30 for it's gas saving qualities. I'm using it in mine but haven't evaluated the results yet. Good luck. Robert Replies to this message: lok888 (Aug 26, 2004 11:26 am)

Replying to: rdaystrom (Aug 25, 2004 8:58 pm) I changed the air filter at 20,000 miles. The old was very dirty. It cost me $13 at dealer. I still get about 13 mph in city stop and go traffic for my EX 4WD. It is very impressive from 8 to 22.5 mpg.
#884 of 1988 rough idle after start up by stz24 Aug 30, 2004 (5:50 am)
After my Sorento sits over night the car starts fine but when it goes to idle down it almost stalls. No check engine light comes on so the dealership has tried several things. they decarboned the induction system,changed the spark plugs,replaced the vacuum control,and checked the connections to the computer. Does anyone have any other ideas.

#885 of 1988 Re: rear brakes and hesitation at 2 to 3ooorpm's [mwitt58714] by renl08 Aug 30, 2004 (5:57 am)
Replying to: mwitt58714 (Dec 31, 2002 6:16 pm) I do know what you are talking about. When I take my foot off of the brake to press on the accelerator, the car makes a thud noise. This started at 3000 miles. I now have 13000 miles and it's getting worse. Now sometimes I even get the thud "pushing" noise even if I'm not at a complete stop (but almost) and then accelerate. I'm also having a problem where first thing in the morning when I press on the gas nothing happens. It hesitates and then takes off. I have to leave off the gas so I don't go flying out into the road. It happens about two more times. Also, there's a big hesitation shifting into first gear. The mechanics haven't been able to duplicate these problems. I can't see how that's possible, but that is what I'm told. Anyone else with these problems? It's a 2004 Sorento EX 4x4. Thanks.

Replying to: renl08 (Aug 30, 2004 5:57 am) I am not sure if you are talking about the "thump" feeling from rear wheels. If yes, you are not alone. My EX 4WD does the same thing. Many Sorento 4WD owners experience the similar thing. This happens when I am taking off from complete stop after I brake from high speed. I believe this is related to the speed. Many said this is normal because of the limited slip differential (LSD) on the car. I didn't bring to this issue to my dealer.
#887 of 1988 Re: Sorento doesn't want to go first thing in the a.m. [stumped] by renl08 Aug 30, 2004 (7:49 am)
Replying to: stumped (Jun 09, 2004 7:16 am) Yes!! I have the same problem. I step on the gas and nothing happens and suddenly it will take off. It does this about three times and then won't do it again till the next morning. However, this is intermittent and doens't happen every day. Maybe every other, every three and then stop for a few days or a week. I also have a 2004 Kia Sorento I purchased in beginning of Jan. The Kia shop is not able to reproduce my problem. Anyone have any ideas what it could be?

Replying to: stz24 (Aug 30, 2004 5:50 am) Hi,   I just purchased a 2005 Kia Sorento EX with the luxury package. After 30 miles it started to idle very rough, it actually shakes the drivers seat and steering wheel. I am taking it in to the dealership on in two days. If you know what caused the problem in your Sorento please let me know so I can help the service department locate the problem. If you do not know what caused it in your Sorento I will repost to let you know what the problem was on mine. Perhapse it could help you isolate your idle problem.   Best of luck to you!

#889 of 1988 Problems with cruise by rosared Aug 30, 2004 (7:58 pm)
I am having trouble with the cruise surging slightly when traveling on a flat surface--this does not reflect in the mph or the tach but you can definitely feel the surge and also it is a mpg killer! I have only had my Sorento two weeks and I am wondering if I made a bad choice. Tonight I noticed the windshield washer didn't work so I added washer to the top--drove a total of 15 miles and it was empty and the light was reflecting empty on the dash--will take that in this week as well. The service Department at Steven Kia in Wichita are horrible. I was there to have the cruise checked and they drove it a total of 6 miles ( they couldn't have gotten to a highway in 6 miles round trip) and told me it was fine--I have had two friends drive it and they can feel the surge like me. They had my car a total of three hours and they had only repaired the left blinker which blinked triple time. There is also a problem with the headrest and they told me they would call me about replacing it and so far NO CALLS--I think Kia has a real problem with their service departments and they need to do something about that!

Replying to: rosared (Aug 30, 2004 7:58 pm) I had a problem with leaking windshield washer fluid immediately after I picked up my 03 EX with luxury package. Dealer service department replaced bottle but still had a leak. Turned out it was the gaskets around the pump. Took about a week for them to get a replacement. After that no problems.
#891 of 1988 Re: Problems by lok888 Aug 31, 2004 (6:39 am)
xmalice - Were you travel at 50, 60 mph or above when you feel the vibration? Like many who experience the similar problem, they found out the problem with drive shaft. Other causes are excess shaft seal, improper tire pressure, balance or wheel alignment.   rosared - See myblacksorento's post about leaking windshield washer fluid. Most of time you and many others are dealing with bad dealers (not Kia) who don't know what to do. I had few issues with my dealer before. I decided to contact Kia for resolution. They (Kia) responded quickly and my dealer became serious on customer service. They also conduct a survey after each warranty repair. Hey! You didn't make a bad choice. Enjoy your new ride! Try another dealer if you feel bad about yours.
