2005 Hyundai Sonata Q&A

2005 Hyundai Sonata Question: What should be included in Hyundai's Factory Recommended 90k service?

We purchased our Sonata in 2005. we're now experiencing possible engine/ transmission problems, the drive train seems to "cough" or slightly slip when the car is in drive and you are applying brakes at stops. We're being told it may be that our transmission needsd t o be flushed or that our fuel filter could be clogged. In looking over our extensive records -- we've kept everything and held to the suggested maintenance schedule fairly closely -- Hyundai shows on their 30k/60k/90k service that "Flush Transmission Fluids" is included as part of these services. Is this something that should have been done? I'm asking because in the itemized details of our receipt we dont see any indication that any transmission fluid was used? Please Advise... -

Try the RepairPal Estimator http://repairpal.com/estimator?car_type_id=4391 Select the Service Type 90,000 Mile Service and update that estimate adding Automatic Transmission Fluid/Filter Change Service. In an article on repairpal.com Encyclopedia they recommend changing the transmission fluid every 30,000 miles. http://repairpal.com/automatic-transmission-fluid-change -
