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.

I wasn’t sure why I needed this to be a PDF, but it was apparent once I got it. It includes what would be thousands of pages if it were in print. The links take you to wherever you need to go in the text.

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.

Fitment for this service and repair manual is set to the 2018 Lexus RX 450h specifically, down to the hybrid 3.5L V6 (2GR-FXS) and the trim your car left the line in, so the clearances, torque values and service steps you follow are the ones Lexus published for this model year rather than a figure carried over from a neighboring year of the RX line.

The slightly opened sunroof spontaneously exploded with shattered glass flying outward and some glass pieces falling on my husband while he was driving. The vehicle can be inspected; however, a Lexus dealership replaced the sunroof glass without charge, the next day after the incident. The unexpected loud explosion with flying glass startled my husband while he was driving. Fortunately, there were no cars around him at the time, because the fright caused by the explosion could have caused a m

I am writing to raise a serious concern regarding a issue with my 2018 Lexus RX450hL involving the brake actuator. Since purchasing the vehicle at 63,000 miles, I have noticed hissing, clicking, and squeaking noises when applying the brakes. As the mileage increased to 83,000, these noises have worsened, becoming unbearable. In addition, I am experiencing a shaky driver-side mirror and a rusting hood latch, both of which present safety concerns. For a vehicle under 5 years old , I believe these

I have a panoramic sunroof and the sunshade retracts when the switch is pressed but the shade bunches up and stops before fully retracting. It appears from online searches that it’s a well known problem with Lexus and can result in a very costly repair that’s caused in no part by the owners of the vehicles. A recall of this manufacturing defect needs to be issued.

On our 2018 Lexus RX 350 L, the left front interior door handle broke and we had to roll the window down and open the door from the outside. I learned that there was a recall - Lexus Special Service Campaign 20LC02 but our Lexus VIN was not listed. Our Lexus Model/year was manufactured in 05/18 and that was within the production period of the recall, April 2015 to September 2018. I believe that Lexus not including our suv's VIN in the recall was an oversight. As a result, I reached out to Smith
