“I ended up to replace every component in the cooling sistem of a total cost aprox. $ 2500 and later on I found here on the net that the 735I's have a recall on their cooling sistem. After all the replacements in the engine cooling sistem , months after, I received a note from the Bmw dealership about the radiator cap. To late. I allready lost more than 2500usd in repairs. My question is: can I get a refund from the Bmw manufacturer for all the loses ? I have all the receipts from my mechanic.thank you.”
NHTSA complaint #746946, filed 2001-06“Recall #98v-178 replaces the radiator cap because the cooling system is not robust enough to hold the pressure of an overheated engine. Bmw states that the result can be a ruptured heater core and possible hot cooland expelled on the drivers legs and steamed windows obscuring vision. All of these conditions do occur and did occur on my car before the recall. The replacement of the heater core cost is about $2,000. It seems to me that Bmw should be responsible for repair of an admitted defect and the replacement of a $10.00 radiator cap is not going to help. …”
NHTSA complaint #744191, filed 2001-04“Car overheated, causing the top radiator hose to fail and also the thermostat to fail as a direct result of the recall. The dealer refuses to fix this problem. I feel this is there responibity to fix the failures. The $466.30 is there estimate.”
