Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My 2003 Bmw Z4 has sticky and/or binding electric power assisted steering control when the temperatures are 75 degrees or warmer, making the car difficult and dangerous to steer. Because of this, oversteering results, which causes the vehicle to lunge into the next lane or onto the shoulder. This becomes a serious safety issue when changing lanes or making minor steering corrections. The problem goes away overnight when cooler temperatures prevail and the power steering unit has had a chance to cool down.”
NHTSA complaint #10353046, filed 2010-08, 35,000 miles“I own a 2003 Bmw Z4 and have had two fuel pumps and filter replacements. The car has approximately 21,500 miles. The first failure was june 2008. The second failure occurred within 1,000 miles of the first replacement. Bmw dealer maintains it is ethanol in the premium gas I buy, which is from chervron. The fuel pump is supposedly subject to failure if the ethanol content exceeds 10% or more. I had the chevron fuel tested and it falls within the 10% limit. All fuels in the pacific northwest contain up to 10% ethanol. …”
