Three wks ago my 08 528I was making a rattling sound in the engine, tin-can sounding. Took the car for service & they replaced my lifters and related parts. They said that the lifters are "known" for going bad on the 5 series and it's typically due to seasonal changes. When my husband brought the car home to me I was very upset because the noise was still there, not as loud as before. I called BMW and made another appointment, citing that this problem had not been resolved and it needed to be looked at again. The appointment with a loaner could not be scheduled for another 10 days, so we waited. During those 10 days the vehicle started to take longer to turnover at start up. I would also feel the engine lightly shuttering as I drove at speeds averaging 35-50 miles per hour. Monday 05/23/11 was my requested appointment; however because my 15 mo. Old baby was ill we had to cancel. Thank goodness we did because my car would not have made it the 20 miles of freeway to the dealership. Today, 05/25/11, I made a left out of my neighborhood and as I accelerated approx. 50 yards, my engine bucked (felt like the bottom fell out), I lost speed dramatically. Suddenly, steering became nearly impossible and I was forced to "turn" into a small shopping center. However, I lost ability to steer upon entering the parking lot. My car would respond to nothing but the brakes (thank god those atleast worked). I looked down at my gear shift to attempt to reverse away from the curb and maneuver into a parking space, though my car was thrown into neutral & would not respond to anything but "park". I attempted to startup again but engine wouldn't turn over. It was dead. Within moments my ABS, check eng, and battery lights illuminated & corresponding msgs came onto my communication screen. Car was towed. Awaiting dealership response in the am. After seeing prior complaints, I see someone needs to be fired. The us government needs to step in before people die! thank god my baby wasn't with me!

The contact owns a 2008 BMW 535xi. While driving approximately 65 mph, the accelerator pedal was engaged and the engine began to sputter with an extensive reduction in power. The contact continued with caution and the vehicle was taken to a dealer where they replaced the fuel pressure sensor, spark plugs and performed an oil change. The failure persisted. The vehicle was taken to the dealer three times in which there were no resolutions. The high pressure pump was replaced on a different occasion. In addition, when encountering a bump in the road and down-shifting from third to second gear, an abnormal clicking noise would occur. Recently, the engine warning indicator illuminated. The vehicle was in the process of being diagnosed. The failure mileage was approximately 45,000. Updated 01/28/11 updated 02/07/11

I purchased a certified, pre-owned 2008 BMW 535xi with approx. 22,000 miles on 10/23/10. Subsequent to my purchase, I discovered the high-pressure fuel pump in the vehicle had earlier failed and been replaced. On 10/28/10, just 5 days after purchasing - I was driving on a surface street when the car began violently shaking and rocking, the engine lost substantial power and nearly stalled, and the engine malfunction indicator lit. I took the vehicle in for service on 10/28/10 and the vehicle was returned 10/30/10. 3 of 4 fuel injectors were replaced along with all sparkplugs. At high speeds, this type of engine malfunction would pose an extreme safety risk in my opinion. I have contacted BMW usa and the dealership where I purchased the vehicle and I have not been satisfied with the response to-date.

Car loses power 2008 BMW.535I had just gotten it out of the shop (new plugs and new brakes, changed the oil air filter full service) and the next day we had gone out for supper when the car would barrly run it was like it had 2 cyclinders. Had the BMW place pick up and they said it was low fuel pump and they had to order. When they got that in it did not fix it so the put another set of plugs and new coils and high pressure fuel pump in also. They ended up covering the whole bill. But it seems not to run like it use to. Not as much power. I would like to find more info on problem and how they extended warranty.*

Engine malfunction light comes on and there is loss of power. This is the second episode. After the first episode I had taken it to BMW dealer, they had it inspected it and said it was a software glitch and fixed it. I happened today again and had taken my car to BMW dealer and they say it is fuel pump problem and gave a Thursday appointment to look into the problem and told me it was safe to drive. Currently I am facing atleast a 40% power reduction.
