Don't panic, this one isn't as bad as it might seem.
Chrysler is currently issuing calls on 142,800 trucks, mostly Jeep Grand Cherokees but some Ram pickups, for problems with the instrument cluster. There are actually two different but related problems, the first being that warning lights will sometimes come on for no reason. This can be annoying and potentially slightly panic-inducing but isn’t actually a safety issue in itself. The second problem is slightly more severe, in that the cluster backlighting will just switch off.
The problem actually stems from a software issue, and this is good news for a couple of reasons. The first is that it shouldn’t be a terribly time-consuming problem for the dealership to fix, and you ought to be able to get your truck back right away. The other reason is that, should one of these problems strike, you can fix it temporarily by simply switching the vehicle off and then starting it back up again. Chrysler will begin notifying owners of affected vehicles next month.
