“Collision avoidance light on, cruise control unavailable, ESC error active safety features inoperative. Dealer states out of warranty. 37,600 miles and dealer wants $140.00 just to diagnose. Average layman cannot diagnose vehicle because of dealer system lockouts. Was intermittent, now on permanently.”
NHTSA complaint #11536888, filed 2023-08“DEF reservoir got low and light came on indicating about 300 miles until truck goes into limp mode 5 MPH. Added 1 gallon of DEF and the guage showed to be in the safe zone. The computer system never registered that fluid was added and truck went into limp mode on the way home. When in limp mode you are unable to move vehicle off the roadway in a safe manner or even drive on any roadway without major risk of getting hit. Truck has to be towed to a dealership to have the computer reset. EXTREMELY DANGEROUS. …”
