NHTSA complaint #11647400, filed 2025-03

Engine: “My 2015 BMW Z4 vehicle has a coolant pump safety recall. It reportedly could cause a short circuit and thermal event or fire. I bought the vehicle while living elsewhere and am now in a small community with 4 major automobile dealers but not BMW. The nearest BMW dealer is about 220 miles away. I contacted that dealer. The service rep said it is 1.5-2 day repair and a loaner vehicle may be available. The repair time sounds wrong but is what she said. …”

NHTSA complaint #11691012, filed 2025-10

Exterior lighting: “Headlights are pointing directly at the ground within 15-20 feet of the front of the car. Driving at night is almost impossible without the high beams lit. This is a safety hazard as you cannot see far enough down the road to avoid obstacles. This was corrected previously and through normal operation the aiming adjust sensor in the rear keeps flipping over center driving the aim down.”
