1 Manifold/header/muffler/tail Pipe problem of the 2006 BMW 325

Failure Date: 11/07/2013

I am writing this department in hopes to resolve ongoing major manufacturing defects on the BMW 2006 325i's. The 325i motor is well known for aluminum bolts snapping on the motor resulting in significant oil leaks and oil pressure. The intake manifold gasket and bolts are well known for prematurely failing and the head of bolts snapping off under pressures. The valve cover gasket and oil pan is also known to prematurely fail due to poor engineers and the utilization of aluminum bolts. BMW fixed the issue in 2007 and replaced defective bolts with iron bolts. The irony is that BMW refuses to acknowledge the issues in the 2006 BMW 325i. Consumers are on the hook for thousands of dollars worth of repair bills because of faulty engine components. The national highway traffic safety administration has received several complaints regarding this manufacturer defect. The aluminum bolts have been redesigned since discovering the manufacturer defect. Bmwna have had numerous service issues related to these defective aluminum bolts. They have all openly admitted that the bolts in question were defective in nature and production, and that the bolts have been redesigned to avoid future failures. Some of these complaints included, and resulted in, vehicles leaking oil in the engine area causing fires in the vehicle. The defective bolts pose a serious potential risk to the safety of the owners of these vehicles, as well as to other drivers who share the roadway with them. It is my strong belief that this type of public safety risk cannot go on any further without proper intervention from the governmental agencies we employ as taxpayers.

2 Manifold/header/muffler/tail Pipe problem of the 2006 BMW 325

Failure Date: 12/01/2011

Noticed aluminum headbolt had broken off and caused an oil leak close to the front of the head on the oil filter side of the block, causing a burning oil smell as oil found its way to the burning hot exhaust manifold, thankfully, it did not catch on fire but I feel that it easily could while driving and could cause a serious accident should I or someone else panicked as it would havw happened, BMW has aknowledged this issue in TSB's and already rectified the issue in the 2007 models of the exact same cars. If BMW does not rectify this issue, my 5th BMW will be my last and I will take my hard earned money to Audi, I find it heartbreaking that a company that used to have such a focus on quality is refusing to aknowledge such failure and to right the situation over a 3$ bolt that has not only the potential to cause harm to many but also to alienate what have been long time customers and true fans of the brand.
