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 2021 Acura TLX was offered with two turbocharged engines across four trims, and this factory service and repair manual is matched to that exact model year, so the specifications and sequences are the ones Acura published for your engine and trim.

Engines

  • 2.0L I4 — 1996cc (122 cu in), DOHC, turbocharged, gas
  • 3.0L V6 — 2997cc (183 cu in), DOHC, turbocharged, gas

Trims

  • Base Sedan 4-Door
  • SH-AWD Sedan 4-Door
  • Type S Sedan 4-Door
  • Advance Sedan 4-Door

Known issues on the 2021 TLX. One recall is on federal record for this model year (NHTSA 24V064000): the front-passenger occupant classification air bag sensor, where an air bag that deploys unintentionally during a crash can increase the risk of injury. Owners have filed 82 complaints and Acura has issued 112 technical service bulletins for the year.

Whether the job is a routine service interval, a control-module reflash, or a hard-to-trace wiring fault, it keeps you on the factory procedure and the correct specification for your specific 2021 TLX.

NHTSA #24V06400001/02/2024Component: AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION:FRONT PASSENGER

Honda (American Honda Motor Co.) is recalling certain 2020-2022 Pilot, Accord, Civic sedan, HR-V, Odyssey, 2020 Civic coupe, Fit, 2021-2022 Civic hatchback, 2021 Civic Type R, Insight, 2020-2021 CR-V, CR-V Hybrid, Passport, Ridgeline, Accord Hybrid, 2020 Acura MDX, 2022 Acura MDX, 2020-2022 Acura RDX, and 2020-2021 Acura TLX vehicles. The front passenger seat weight sensor may crack and short circuit, failing to suppress the air bag as intended.

Consequence

An air bag that deploys unintentionally during a crash can increase the risk of injury.

Remedy

Dealers will replace the seat weight sensors, free of charge. Owner notification letters were mailed March 28, 2024. This is a phased recall. Owners may contact Honda customer service at 1-888-234-2138. Honda's numbers for these recalls are XHP and VHQ.

NHTSA #24V95000019/12/2024Component: FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY

Acura (American Honda Motor Co.) is recalling certain 2021-2023 TLX vehicles. The fuel filler neck and fuel tank may have been improperly welded, which can result in a fuel leak.

Consequence

Remedy

Honda (American Honda Motor Co.) is recalling certain 2021-2025 Acura TLX, 2023-2025 Acura MDX, and 2023-2025 Honda Pilot vehicles. The brake pedal pivot pin was not secured properly, which can cause the pedal to shift out of position. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard numbers 108, "Lamps, Reflective Devices, and Associated Equipment" and 135, "Light Vehicle Brake Systems."

Consequence

A brake pedal that shifts out of position can prevent the driver from applying the brakes as intended, increasing the risk of a crash or injury.

Remedy

The front passenger seat weight sensor may crack and short circuit, which can cause the air bags to deploy unintentionally during a crash.

Consequence

Air bags that deploy unintentionally during a crash increase the risk of injury.

Remedy

How Acura Lost my Business The fact that no one from Acura will take responsibility for the ongoing issues has reaffirmed that my long-term commitment to owning Acura’s is over. Honda will only communicate via the phone and say "if the dealership can't fix it, neither can Honda."

The last straw was when I looked up the Acura TLX Blue Book value; the car had a safety recall I knew nothing abo
