Electronically Assisted Anything
“As far as parts' cost goes, electronics are the ones that'll always sting,” says mechanic-turned-auto journalist Justin Mastine-Frost, adding that “anything on the audio/infotainment system won't come cheap." The same can be said for issues with certain cars' computers and sensors. According to Mastine-Frost, on the second-generation BMW X5 SUV, sensors were built into the struts of the active suspension, instead of the shocks, so each strut could cost close to $1,000 each — not a couple of hundred bucks. “The sensors would fail, but the strut would still function, but you were still out a grand plus the [repair and replace] cost,” he says.
The Cheap Fix: Luck.
