The download I received was a complete waste of my money. Was not even close to what it was represented as. I thought I was getting a proper service repair manual. What I got was a collection of service bulletins. I sent an email to your company right after I looked through it requesting my money back. Have yet to hear a response. Terry Muich

It was much larger than i expected. 5 documents at 12k pages each. Its not something ill actually be able read but its easy enough to find what you need..
The Ford F250 manual is much easier to navigate at just over 8000 pages.
If i spend the money for Adobe Acrobat Professional ill be able to break it down into manageable bits.
Both manuals area great value for the money.

would rather have a maintenance manual. have a parts manual from parts vu company. only difference is that your parts manual has all together whereas the parts vu had to download the differsections individually.

Our original order was supposed to be for our 2014 Subaru Outback, yet the manual came up as Forester. We did have to purchase a new manual in order for them to send us the correct manual. We hope it will help us repair our Subaru.

Item as described quick delivery

The 2018 Hyundai Sonata was sold with five engines and eighteen trim levels, and the factory figures do not carry across all of them. This service and repair manual is written to the 2018 Sonata as it left the line, tied to your car's engine and trim rather than approximated from an adjacent model year that happens to share the same body.

Known issues on the 2018 Sonata. One recall is on federal record for this model year, and it covers the trunk lid latch. Hyundai found that the trunk latch may become damaged, and a person inside the trunk compartment may become trapped as a result, increasing their risk of injury. Owners have filed 532 complaints for the year and Hyundai has issued 144 technical service bulletins.

Whether you are working on the trunk latch, on the turbocharged or hybrid versions of the 2.0L, or simply hitting a scheduled interval, this manual holds you to the specification Hyundai published for your 2018 Sonata.

NHTSA #21V61900006/08/2021Component: LATCHES/LOCKS/LINKAGES:TRUNK LID:LATCH

Hyundai Motor America (Hyundai) is recalling certain 2017-2018 Sonata, 2016-2018 Sonata Hybrid, 2018-2020 Accent, and 2016-2017 Azera vehicles. The trunk latch may become damaged, preventing the opening of the trunk from the inside. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."

Consequence

A person inside the trunk compartment may become trapped, increasing their risk of injury.

Remedy

Dealers will replace the trunk latch base, free of charge. Owner notification letters were mailed December 4, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 208.
