Hey there, i'll start off saying that i'm not super knowledgeable about cars, so I could have a few things wrong. So just a heads up. Thanks.

My 2009 Nissan Murano recently had an all of a sudden issue with the brakes after my wife hit a pot hole. We've taken the car to three different mechanics and have all leaned towards the abs module/assembly being the issue. Two can't properly work on it because they don't have the right tools, and the third is pricing the repair at $2,843. This is a crazy expensive repair cost to all of a sudden have, so I looked for salvage/used parts for the repair to get the price down, but according to the mechanic, a used abs module/assembly is unpredictable and might not be "compatible" with my Murano. Why would a used part not be a suitable fix for the repair? Also, I know a dealership would be the quickest and easiest way to go, but I was trying to avoid a kings ransom worth of money needed for a repair, although it's appearing that it'll be expensive no matter which way I go.

Lastly, the guy was talking at a million miles an hour over the phone trying to explain everything, so it was a little hard to keep up, so I could have a few things wrong, but I believe I have the main points. I'll be heading down to talk to him in person tomorrow.

Thank you for any advice and help that you can give.

Just had the same problem with my ABS system in my 2009 Murano. After coming to a hard stop and using the ABS system, my brakes were spongy and went all the way to the floor. After reading these threads and the ongoing investigation with the NHTSA, I decided I had no choice but to take it to the Nissan dealer. It was indeed the ABS Actuator and cost me $2,500 to repair. The part alone was $1,900!!!
I filed a report with the NHTSA and will just hope that they do something before people get seriously injured. I also learned that the dealerships are not even allowed to look at the ABS system to see if it is broke. Furthermore, I am not even sure that this new actuator fixes the problem. I may still be in danger and not even know it. File a report if you haven't already. I had just paid $900 in March for a defective lift gate actuator. Not happy!!!
