“While driving my vehicle at high speeds on an interstate, the battery warning light activated. Before I was able to pull the vehicle over the air conditioner I'll probably begin to stop working. Following this, a series of multiple warning lights activated. The vehicle would not accelerate and I was forced to pull over. Following this, the vehicle would not activate whatsoever. All power was lost. I could not shift gear. The car required a tow to the local dealership.”

“The DC/DC converter is failing on the vehicles regularly. This results in the vehicle losing power and shutting down while driving. I own this vehicle and while it hasn’t happened yet, I constantly fear that it will. With the common knowledge and frequency of this occurrence, Land Rover should fix as a recall to ensure the safety of all customers. Please push for this. Thank you.”
