First my rear electronic shocks when out, on my 2007 Sport MDX, then a few months my front passenger strut when out.
Initially, I bought/replaced the bad rear ones with kyb shocks and all 4 of the resistors.
I did not get any warnings, because the computer saw the resistors.
Of course, the front shocks didn't act like electronic shocks anymore, because they were not getting any signals, from the computer.
I started shopping around for free shipping on the front struts. I replaced the fronts as a pair.
I spent $700 (shipped) for all four corners, resistors, and front end links.
Once you decide that $4k - $5k is too much, to spend every 40,000 miles, start shopping and fill your parts list.
