Four problems related to engine and engine cooling have been reported for the 2004 BMW 545. The most recently reported issues are listed below.
Drive moderately keeps popping up an service engine after getting BMW to check it an fix it also it won't crank sometimes but the battery an alternator is brand new but after it sit for hours it finally crank up, maybe it's an security issue but it's unnecessary.
Transmission jerks and slips. When coming to a stop, the car slams into gear. This could cause a major accident if this occurred during wet or icy road conditions due to breaking traction from wheels and road surface. This is a major concern and after doing some research, thousands of 5 series BMW's have this problem. The result is a defective mechatronics which costs between $5000-$8000 to fix and not covered by BMW or under warranty.
Intermittent harsh 2-1 downshift (jolt) when coming to a stop with light brake application. Jolts and/or jerks felt when reaccelerating after coasting. Judder when gently accelerating (most noticeable at an engine speed below 2,000 rpm).
When beginning to drive, the vehicle would slam to the point where I thought I was rear ended. I took the car to my mechanic and he said it was the transmission and the fix was costly. Continues to do this at times and will also do a smaller scale slam when slowing to a stop light or stop sign.
