NHTSA Complaint #11675495 — 2016 DODGE DURANGO

Driving in the left lane of an interstate highway at 75mph, in moderate traffic, in daylight hours, clear weather, with my young son. Sudden, unexpected decrease in engine rpm resulted in unannounced, approximate 40 mph reduction in speed. The instrument cluster illuminated stating “ service transmission continue in D. Do Not Shift or Turn Engine Off”. Such an unforeseen event, without brake light illumination, resulted in several following vehicles to take evasive actions, thus preventing a potential mass casualty accident. I was able steer towards the right shoulder at the greatly reduced speed of 35mph, collect myself, check on my upset son and try to make sense of what had happened. At this point panic began to set in. I called my Father & he was able to provide the next step being to deliver the vehicle to the local Dodge dealership. Those few miles were miserable since the dash was still presenting dismal warnings, there was reduced power and the vehicle acted like it was in a very low gear. The dealership was closed, so the vehicle was parked on lot however, once the engine was turned off the battery power remained on. Unable to lock, turn off or change any electrical device. We returned the following day and spoke to the service advisor who stated, “the vehicle had entered the Limp Mode” Addition research states it is a safety feature that activates when a critical issue is detected by a computer. Well, I guess the engineers never thought about such a radical transformation at highway speeds….without brake lights! Such a device should never allow an automobile to suddenly and without notice, startle the driver with annunciations while simultaneously downshifting and reducing engine rpm.
