Asked by Ian
The auto disabling of the blind spot monitoring system in my 2023 Isuzu MU-X works when I connect my genuine Isuzu 12-pin plug and wiring loom. The disable function works for a short time but then fails (after around 30 minutes, the BSM turns back on). Isuzu says that it is not a common problem and seems not to know how to fix it. Are you aware of what the mechanism is that switches it on/off and if there are any issues with it?

24 Jan 2025I’d be interested to know what happens after the 30 minutes when the system switches itself back on. Does it disable again if you give the connecting plug a wiggle? If so, it’s probably a poor electrical connection somewhere inside the plug assembly. If you need to turn the ignition off and back on to make the system disable itself again, then you might be dealing with some kind of computer (body computer?) problem.
The thing is, if this is a genuine Isuzu accessory option, then it should come under the car’s new-car warranty. At which point it’s Isuzu’s problem to fix, regardless of whether the dealership you use has seen this issue before or not.
