Power Train Problems of BMW 545

I started having problems several months ago that has progressively gotten worse. When I accelerate from a stop, it appears that the automatic transmission is struggling to get to the next gear. The rpms will fluctuate up and down and sometimes rev way up before the car kicks like I have been hit. If I try to accelerate fast from a stop, the engine will rev up to about 5k rpm and stop responding until I let off the gas and let the rpms drop down and then it will kick into gear. If I slow down to almost a stop and then accelerate it will most certainly kick, so I have to be very cautious. I have to make sure I have plenty of room when pulling out of an intersection because I never know when it will act up (which is most of the time) and hinder my acceleration. Once I get up to cruising speed (above 45 mph) it runs smoothly, but it has gotten to the point that I dread every time I have to stop at an intersection or slow way down. I talked to the dealer and said if it was the transmission then the service light would come on. He asked me what kind of gas I use and I said shell high octane and he said that is good. Other than that, he didn't tell me much more. I want to sell the car next spring but who will buy it with it performing this way?.

When driving between 35-40 miles per hour the car has a very bad jerk like it doesn't know what gear it wants to be in. And sometimes it feels like the car is getting hit from behind with how hard other jerks are.

Vehicle slips in an out of 5th and 6th gear when traveling at constant 35 to 40 mph in auto mode and around 60 mph in ds mode. Noticeable oil leaks as well as occasional smoke from tailpipe and vehicle bangs into gear ( while downshifting on occasion) also noticed that the electrical system seems to cut out for a split second while driving. Heads up display and radio illustrates this finding as they shut off for a second. The clock is also behind a few minutes / week because of this.

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).

An excessively harsh 2-1 downshift when decelerating to a stop, or transmission "bangs" into gear when accelerating from a full or a "rolling" stop (vehicle did not come to a complete stop).

2005 BMW 545i. Consumer writes in regards to several issues with vehicle to include passenger side airbag, transmission issues and leaks the consumer stated the issue with the passenger side air bag was recalled. Even though the part was replaced twice under warranty and exhibited the same symptoms as stated in the recall, the consumer's VIN was not included. The consumer also stated there was a jolt/delay when pulling away. Within the last three months, the transmission would shift between 30-40 mph as if it were not getting enough fuel. There was also a coolant leak coming from the valley pan, a hose and the coolant tank were replaced. The engine was replaced in 2008, and since then, the vehicle used excessive amounts of coolant.

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.

Car slams like you just got rear ended if you speed up while rolling at around 35mph. This is very dangerous as it happens when I'm trying to change lanes and speed up. Also transmission jerks as if you are missing a spark or it is trying to find a higher or lower gear while cruising in traffic between 32-40 mph. It jerks noticeably where my son asks why are you driving like that. This is terrible and needs to be dealt with, regardless whether the car is still under warranty or not. None of these incidents signals a check engine warning. The bang at rolling is enough to give one whiplash.

My BMW 545i 2005 has experienced problems with mechatronics for some time. One day I was driving home and my car has down shifted from high 4th gear to 2nd and caused me to drive into a ditch. Luckily I was wearing a seat belt but still experienced neck injuries from hitting the ditch. This problem needs a recall before some one gets killed. BMW can no longer cover this up and this issue needs to be investigated. Many forms on the internet have addressed the same problem. This is no longer a issue, its a life safety problem.

I have been reviewing blogs on the 2005 BMW 545i series. About a month ago I started experiencing issues with my car. The car is accelerating at times on its own as I switch the transmission into drive and I let go of the brake. It gives a boost of acceleration where I almost hit my garage door. On several occasions when I roll from a stop sign the car experiences a big jolt as if I just got rear ended. It is so hard that my 4 year old got flustered and started to cry. At 30-40 miles the car started to jerk as well. I took it into BMW but since the sensor does not pick up the problem they was nothing they could do according to them. They informed me that it is hard to tell what is wrong it could be transmission, sensor, brakes, engine, etc. . . I feel they know but do not know what the extend of the problem is. There is a problem and they need to admit it and it might be an electronic issue with the gear box functionality. It seems they need some pressure before it causes a fatality. The acceleration and jolt are a big problem. Please address and let's not add to your number of deaths column before you react.

Engine stalling while driving vehicle, unable to restart vehicle after the stall. Loss of power steering and brake power assist when vehicle stalls while driving. Engine stalls very periodically after a short period of operation. Took vehicle to dealer 3 times and were unable to pinpoint the problem. Dealer replaced battery and electrical wiring to fix problem but problem still continued. Also a brand new alternator was replaced and still same problems arose. Message center would display "transmission fault" drive moderately.

The contact owns a 2005 BMW 545i. The contact stated the air bag and power transmission warning light illuminated on the instrument panel. The vehicle also occasionally stalled while driving on the highway. The dealer and manufacturer were notified and made the contact aware of the NHTSA campaign id number: 05v504000 (power train:automatic transmission) and the NHTSA campaign id number: 08v384000 (air bags:frontal) recall, but the VIN was not associated. The vehicle was not repaired. The failure mileage was 104,000 and the current mileage was 112,000.

For many years, and after many "repairs" my 2005 BMW 545i, which I bought new, has never run right. BMW is aware of the problem, does acknowledge that it is an issue, but has been unable to repair it. I have spent many thousands of dollars in search of a permanent fix, but the last BMW dealer I dealt is miffed on solving the problem. When approaching between 25-35 mph, the transmission "slams" and feels like you have been rear-ended. It is a continuous problem. I have to slightly let up on the gas in these speeds in order for the car to run right without an emergency light coming on saying "transmission fault; drive moderately. " this can be a dangerous situation because the car is sensing the fault and it will not allow one to drive much above 50 mph without straining the engine. Going down the highway at 50mph in my area can be a hazardous activity! this has been a continuous situation with the car since I purchased it up and thru the present date, Aug, 21, 2014. I have no faith in the engine/power train/transmission. This is my first and last BMW.
