“Bmw - vent valve the vehicle is obviously engineered wrong and the company should be liable. The dealership told me it would cost $1,000 to replace and cleanup a frozen vent valve due to condensation from moisture. The extreme weather where I live cause the condensation to freeze causing oil to backup and blow the engine.”
NHTSA complaint #10255314, filed 2009-01, 10,000 miles“My 2001 Bmw X5 has serios issues with its design that Bmw corp refuses to acknowledge or fix. 1st there is a faulty design on the pvc causing the valve to freeze and drain the oil into the engine. This almost caused a fire in my car. And cost me about $1200 to fix. 2nd there is a design flaw with the front doors whereby the either freeze shut or refuse to lock in temperatures below 17f. This is a hazard waiting to happen. Please help us ( consumers) since Bmw apparently has no interest in adressing these issues.”
NHTSA complaint #10213628, filed 2008-01, 88,000 miles“I have a 2001 Bmw x-5. On a cold day in january of this year I left work and drove approximately 25 miles when my yellow check oil light came on. I could smell oil and noticed that my vehicle was smoking out the exhaust pipe. I went to the nearest service station and turned off my vehicle to check the oil. When I pulled out the dip stick, oil shot out of the hole and sprayed all over the interior of my hood, on my face and all over my clothing. The oil crankcase had become pressurized and was forcing the oil out the engine, through the rings and valve covers. …”
NHTSA complaint #10222050, filed 2008-03, 106,000 miles“Bmw x-5 coolant system failure with only 26,800 miles. The coolant reservoir and tubes to the radiator burned out. Also 3 power window regulators malfunctioned. At this moment fixed but unacceptable for the cost and engineering of the car. All parts were replaced and supposedly new. Did not see new or old parts.”
NHTSA complaint #10104079, filed 2004-12, 26,780 miles“On cold day, '01 Bmw X5 3.0, started, briefly warmed and driven 8 miles b/f engine quits and will not restart. No warning lights, nor overheating involved. Mechanic indicates engine completely seized due to oil separator freezing from residual condensation in air as well as crankcase resulting in oil forced into cylinders, choking motor, and cracking connecting rods. Engine has now failed requiring a new or used motor - estimated at $7,500 replacement (not to mention significantly lowering resale value since new motor will not match VIN). …”
