Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct. Also, make sure the computer that controls the transmission has the most up-to-date adaptive programming information. When servicing these transmissions be sure to use fluid approved by Hyundai.

If the Check Engine Light illuminates, indicating a problem with the front oxygen sensor, but the sensor tests okay, reprogramming the engine's control computer should fix the problem. Then, the Check Engine Light will no longer falsely illuminate and the acceleration, particularly from a stopped position, will be smoother.

Electrical & Lights -- Verified

If the alternator fails, it should be replaced with an improved design which is better able to replenish electrical power to the battery. The new alternator requires a different diameter drive belt.

2005 XG350L. It's a great car. Have had it for seven years. 25 mpg.

My dashboard top facing the front windshiled strted to spilit on driver side because of the Sun. I can still push it down and it stays for a day or two, Is there cheaper way to fix it?

I have owned my car for six years now and still love it. It has almost 250,000 miles on it and am hoping it goes another 250,000.

I am having issues with my hyundai. The check engine light has been on for sometime, and the engine codes say "limp home". The car does shift rough sometimes but my main problem is when I am accelerating at high speeds ( 60mph and above) the car shakes/ vibrates. I do not think that it is the balancing of the wheels because it only happens when I am accelerating, if I take my foot off the gas the ride is smooth. I am a single mother and am trying to figure out what the problem is without spending loads of money.

i boughht my xg350 with 86,000 plus miles in october 09, thank goodness for extended warranty, it has saved me many times, the calipier freezes up quite often, is that normal?
sadly, my extended warranty ended in match 11 and since its been a money pit, meaning it all started with a simple oil change and fuel filter change and its been one issue after another and this atm is dried up. to date, i now have 125,000 plus miles, what else could go wrong or is it in my best interest to get another extended warranty?
im really worried about the belt breaking, so i had it inspected by 3 different mechanics, all 3 said it was good, what does that mean in the mechanic world?
i know it will cost roughly a grand for part and labor.
my air condition squeals every time i turn it on, so i just suffer thru the mn heat, what does the squealing mean?
any input is welcome, thannk u
