In March 2007 low coolant warning caused me open hood and add coolant three times before I took car to BMW dealer, who diagnosed cracked plastic reservoir in radiator and separate coolant tank. Each time engine had overheated due to a lot of pressure under radiator coolant cap. Needed much time waiting before opening to add coolant. This was defective materials and not normal wear and tear breakdown. Every preventive maintenance has been done by book on this BMW. Manufacturer disclaimed responsibility as car out of warranty by few months. Car had 54,000 miles. Plastic was found hardened by heat and brittleness cracked the same. 339 other BMW 740il owners have filed petition on internet for same cracked plastic radiators (on BMW 740I, and il models between years 1995 through 2001. BMW ignored our pleas for free replacement. Major safety issue not expected on premium car like this.

I need to have a new engine put in for my 2001 740I BMW due to a cracked radiator which led to the damage of the engine beyond repair. The car has 68,000 miles on it. I was fortunate that I was not injured and I did not cause an accident on the highway. I contacted the company explaining my situation. BMW refused to acknowlege that there are some major defects with the radiator and refused to help pay for the cost of the new engine. I have done some research on the web and have found that many BMW owners especially BMW 7 series model have gone through the same problem. There's also a petition concerning major defects with all BMW 7 series' radiator. The defects have caused the cosumers costly repairs not to mention dangerous driving conditions which could lead to serious injuries or even deaths. Thank you for your consideration! regards, chi truong
