Filed Jul 28, 2022 · Electrical, Engine · CO

The oil filter housing gasket, the mechatronic transmission and the electrical system failed. Yes, it is available for inspection. My safety and the safety of others were put at risk as a result of my vehicle losing power suddenly while I was driving on the highway. I was driving at the highway speed limit and my vehicle malfunctioned and lost power while others were at high speeds. I had to abruptly stop almost causing an accident. The problem has been reproduced and confirmed by the BMW service center. The vehicle has been inspected by the BMW dealer service department. The warning lamps that came on my dashboard were the check engine light, oil level light, and the transmission light. The car was running poorly. The engine wouldn’t crank and then it would jolt after driving. I would smell oil occasionally. The symptoms first appeared in 2011. I had my vehicle serviced at BMW regularly. In 2016 the symptoms got worse despite having my vehicle serviced for the same issue. I had the repairs done at BMW and when I drove it for the first time after getting it repaired it still failed.

The car has had numerous issues since purchased. This all came to a head when driving home, under normal conditions, it suddenly would not shift past 1st gear. I proceeded to pull off to a side street and attempt to idle home, as I was about 1 mile from home. After approximately .5 mile, the transmission suddenly lost first gear, there was an audible bang under the hood, and the car completely lost power. After being in a service center for a couple weeks, I am now informed that the engine is locked down and that the car will require a new engine to be working again. This car had been an absolute nightmare and has turned me quite calloused towards bmws quality standards.

Bmw 335i 2007 has (x3)three times now, the vehicle was traveling during the daylight hours at highways speeds of 65-70mph in the number 1 far left lane of (ca 101 fwy) in may of 2016 when the vehicle displayed 'engine temperature was high, and that the car needed to be driven at a moderate speed'. Immediately took my foot off the accelerator and began to coast in idle state to the shoulder (ca 101 fwy) 5 lanes over. Before I was able to move to the 3rd lane the vehicle stated 'engine to hot', turned off, lost power (much like if you run out of gas), and I frightfully merged creeping along to the shoulder narrowly missed being hit by several other trucks and vehicles. I went to lift the hood, expecting to be overwhelmed by heat and conditions that would cause a bmw to disable suddenly and lose power. I observed no conditions of heat or unusual to cause a shut down. I was able to turn car on again in 10 minutes with no problems the temperature was no different or warmer than I have ever felt before, conditions were 72/*f, traffic was moving along at a good flow, with light cool bay area breeze. This has occurred 3times now, I have filled the coolant, I have had the starter and battery replaced and yet the same occurrence comes up.

While driving on the hov lane of the freeway during rush hour about 5:15 pm my car suddenly started to rattle when pushing the gas peddle. I took my foot from the gas peddle while still driving with about 60 MPH. I tried the gas peddle some seconds later again and experienced still rattling and no acceleration of the car. I took my foot again from the gas peddle. In the meantime I was down to 40mph. About 20-30 sec later from the first rattle the engine light came on and 1 sec later the engine stalled on the highway. At that time when the engine stalled I was still driving about 35 MPH. Luckily the freeway had a left shoulder and I turned over to the left with the last remaining speed and slowly stopped the car. I'm so glad that the left shoulder was available. The freeway was very busy and I assume I would have been involved in an accident, if the left shoulder wouldn't have been available. The loss of power was too sudden and entirely unexpected. The stalled engine created a very dangerous moment while driving on a freeway. The bmw shop came back to me today and explained that the high pressure fuel pump failed. A know issue with the car make, model and year.

This is a know issue that bmw dose not want to resolve in all of their dealership. The problem that we are talking about is that the transmission shudders an vibrates between 1,700 and 2,200 RPM in 3rd,4th,5th,6th gear. The loss of power has almost cost me several accidents. Bmw says that they will flush the transmission and replace the transmission fluid in hopes to fix the issue or possible replace the entire transmission and torque converter.. Every time I go and try to get them to fix it they want to charge me for a know issue that have. I have been a loyal bmw customer and to be treated this way is just wrong. Especially when it comes to safety and the safety of others. Bmw show take ownership of this.

While trying to pass on a busy highway I was trying to excel speed get pass semi truck. When out of no where my car loss power and almost caused a huge accident. I wasn't prepared for that, or have heard of such a thing. After researching it seams to be a bmw problem with these cars. I literally just got my car back from my local bmw dealer in charlottsville va same day.spent a lot of money on this car and planned on keeping it for at least another 7 yrs or more. Usually if you maintain your car it will last forever, but guess not if the actual dealer doesn't know how to manufacturer one correctly. This was a car I always wanted bmw is known luxury and sport . Just crazy they do not respect the customers more than they do. I just wanted put my complaint in with everyone else's, seeing there's a lot.

My serpentine belt (drive belt) snapped and shattered causing my vehicle to lose power steering capabilities. This belt drives all the accesories( alternator, power steering, AC, etc). This is a known issue by bmw, there is a sib 11 09 08 that states the issue and how to go about checking it by the dealer. The issue is the design flaw in the power steering pully hitting the sub frame and causing damage to the belt and in turn the belt snapping. This can/will cause a fatality one day because of the loss of steering controls. The belt on my vehicle was replaced before on 12/20/12 for the same reason and it has only been 1.5 years and the same problem.

While accelerating on a highway, the car lost power and started to shake. I had to pull off on the shoulder while decelerating while cars around me were honking and driving around to pass me. I was lucky not to have been in a collision. The "engine malfunction" light and "service engine soon" light turned on. After coming to a stop on the side of the road, I turned off the car for a few minutes and restarted it - it drove fine but the "service engine soon" light stayed on. It has happened many times since.

I was driving home on the freeway when all of a sudden car immediately lost power, engine over heating illuminated on my message board. Had to cross two lanes of traffic while speed was decreasing, I thankfully made it to the shoulder. Car would not accelerate past 2mph. Called tow truck and sent to bmw. Car read 62,000 miles, bmw replaced waterpump ($1,600). Vanos sprockets that prematurely fail are a known issue at the bmw service center here in tx mine failed at 63,000 miles ($1900). Passenger mat sensor seat sensor failed at 63,000 miles ($800). A well known issue at the bmw dealership bit they do nothing about it... Now my turbo chargers have failed due to waste gate but thankfully bmw extended the warranty to 82,000 miles. This is the worst bmw I have ever purchased never have I had so many problems with the 335i. Advice stay away from the n54 turbo charged bmws. Buy an audi.

Car started to rattle especially upon pressing gas pedal while running at around 50mph in a freeway. Significant reduced power was noticed. Soon "service engine soon" lit on the tachometer. When stopped a raw gas to rotten egg smell was around the car. By turning on/off ignition several times, it stopped rattling and regained full power. Same issue happened again on a local road at around 50mph about a month later. Power regain was achieved through same way. "service engine soon" light went off 24hrs later. Brought the car in to a local bmw center. Upon diagnosis, cylinder #2 misfire and both pre-cat or post-cat oxygen sensor low response. A service agent decided not to do anything at the moment because he couldn't replicate the issue I described although he did find the malfunction codes. He instead told me to bring the car when the same symptom occurs. He also said that the technician who looked at the car believed that a faulty fuel injector might have caused the misfire and both oxygen sensors malfunction consequently.

My bmw lost power on multiple occasions.it was in bmw service for 6 weeks discovered a problem with manifold "leaking oil and no power to twin turbo. Factory man could not find the cause. They had to tear down the engine finally after we were losing our patience to finally "find the problem". This was when the car was brand new. Have had multiple trips to bmw service for stalling and loss of power on the road. Have had to reset the"cars' "system again on 2 occasions.bmw did extend the service warranty on the turbo and fuel pump. Tonight had complete power failure on highway. Had to stop and start and go several hundred feet.car limped home into the garage. Im sure my trip to the bmw service station will be an exercise in futility since they tell me the car is fine. There must be some issue with the twin turbo engine.
