Hi Everyone
I have recently purchased a 2008 Grand jeep 3.0 CRD Cherokee
At random times most of the dashboard warning lights light up flash
The speedometer & Rev counter needles go up & down
I am still driving the jeep at this time
Also limp mode is activated

if I stop the jeep turn off the ignition & start up again the problem stops but does reoccur at random times

I can only think this is perhaps a common electrical fault?

any help would be appreciated
