Potential Consequences:

The other day approximately 5 minutes after leaving my house I noticed a smell and saw some slight smoke coming from my rear window.

Unfortunately the dealership will not help me until there is a recall with my vin as there is not an open recall on my vehicle.

EXTERIOR LIGHTING

Potential Consequences:

Intermittent issue with entire dash lights and radio lights going either fully out/off or extremely dark. Adjusting dimmer does not correct the issue. Affects driver safety due to acute driver distraction while trying to correct, and disables driver warning lights and all information systems, including towing related warnings (transmission temp/coolant temp, etc) Dealer advises to bring it back when it is occurring, but occurrences are not predictable, nor do they occur on a regular basis. Cause is unknown, but since dimmer switch does not correct this issue, it is the probable cause.

When it does regen, sometimes it takes hours. Dealer says needed a manual regen & that is their solution. Yet problem persists.

Additional Notes:

While towing our trailer, truck went into reduced power mode, regen message displayed; check engine light came on; loud bag occurred and hissing from under the hood. Truck slowed to 3 mph so we pulled to shoulder and turned the vehicle off. Truck had blown the hose off the the turbo. We reclamped and restarted. Displayed check engine light, reduced power & regen message to keep driving however truck wouldn’t go over a 3mph crawl. Truck lost all power, everything shut down and wouldn’t restart. No dash lights, no error, no crank, no power. We were dead on the highway in the truck lane while towing. This Truck goes into reduced power mode every time it tries to regen and we have had it to the dealer multiple times however, the problem continues to get worse. When it does regen, sometimes it takes hours. Dealer says needed a manual regen & that is their solution. Yet problem persists.
