Active air flaps malfunctioning, sevise bulletin for other models but not this one
My backup camera doesn't work (engage) when the car is in reverse. Anytime the car is placed in reverse the backup camera should come on. I have other cameras that i can't access, but the backup camera is safety related.
Not really sure if this would be considered a safety complaint, but it could lead to problems if not corrected. The upper radiator shuttle will not function properly. This can cause restricted climate control in the vehicle interior, reduction of engine performance and possibly engine overheating. This appears to be a common problem with model years 2016+. I noticed this when i turned on the car and the check engine light came on. There is no visible damage to the shutter. The link below is for another model of bmw, but shows that this is a known problem: https://static. Nhtsa. Gov/odi/tsbs/2019/mc-10160279-9999. Pdf
On july 30, i was driving at 35mph on a major road in pinetop/lakeside, arizona when the sunroof, that was in the vent position, exploded inward showering me and a passenger in shattered glass. It was not struck by any object prior to the explosion. Due to extensive damage to the sunroof cassette, the repair is about $7,000.
The sunroof exploded out while driving about 45mph. Most of the glass exited the vehicle above but many shards of sharp glass sprayed all four passengers. All four passengers received minor cuts. No rock or other foreign object was observed impacting the vehicle. The glass exploded out not in. The outside temperature was about 7 degrees f. This occurred on highway 99 between whistler bc and squamash bc on february 3, 2019.
On two occasions a false fasten seat belt from passenger side has come up when the seat was not occupied. The car was sent for repair. On the first occasion it was indicated the wiring is loose for the seat belt harness so it was tightened. On the second occasion the car was sent to dealership it was diagnosed that the harness wiring track could come loose and therefore had to be rerouted.
I got engine malfunction light on two separate occasions on my bmw; on each occasion the car was sent to dealership for repair to find that the upper and lower radiator blinds are at fault and this required replacement. The 2016 bmw 740i is equipped with a front grille where the vents are covered by blinds that open when the car is started and closed when the car is turned off allowed some time for warm air to come out of the engine compartment.
Active pdc fails on multiple occasions. A technical service bulletin was released in march 2017 by bmw and new software was downloaded. Despite the new software downloaded to vehicle there continues to be incidents post that when the active pdc fails to activate. Bmw continues to claim the feature works as designed but there is never any explanation by the dealer why it is by design. Foreman at the bmw dealership where he witnessed multiple failures of it argued that i can see the car is going to hit another car or an object so why is it necessary to have it activate? This argument does not make sense, because the feature should work, and if you know car is going to hit another car or object then you should expect feature to activate otherwise why is the feature. Dealership service department would not accept to document the failures in the service order or the arguments foreman made.
Audio control system freezes on the bmw 740i. It happens that audio is gone completely, system does not respond to any of the following to raise volume: 1. Gesture commands to raise volume (the system does not even show gesture is involved on the dash display) 2. From the power button by manually adjusting higher, there is no response from system at all and dash screen does not show volume increase is being attempted. 3. From the volume up button on the steering wheel, again no sign on dash screen that volume increase is being attempted.
The problem is centered around adaptive cruise control system of bmw 740i 2016. Bmw 740i can't detect vehicles from the right corner or left corner when two lanes merge into one and the bmw is approaching the other vehicle where the other vehicle is either at front right or left right. There are multiple symptoms of this problem: first symptom, bmw 740i is not tracking any vehicle and cockpit does not show a tracked vehicle. A car or big truck is in the second lane merging from either corner, bmw 740i does not detect though there was enough time and distance to detect. In one example there was 18 wheeler merging lane and bmw never detected the 18 wheeler though majority of the 18 wheeler was ahead of the bmw from the right corner. Second symptom is bmw 740i is tracking another vehicle, when two lanes merge there is a car from the other lane coming in front from the right corner or left corner, bmw never slows down further since that vehicle is already now in view of the bmw. My understanding the bmw uses the camera behind the rear view mirror, facing forward, to detect such scenarios.
2016 bmw 740i is equipment with automatic park distance control system (pdc) that automatically activates when the vehicle is close to an obstacle when driving at very low speed. The system is very flaky in terms of performance, sometimes it activates when it is 2 ft away from object and many times it activates when it is only 2 inches away. In some instance it fails to activate completely so manual intervention is required to activate sensors. Dealer tried repairing twice including new software download and calibration of sensors but the problems persists and they say nothing is wrong. *tr
Vehicle is equipped with adaptive cruise control and pedestrian detection feature. The adaptive cruise control misses to adapt speed or stop or detect a vehicle in front requiring driver intervention to avoid a collision. I have seen multiple symptoms of this problem occurring. Symptom 1: vehicle bmw with adaptive cruise control is tracking another vehicle and adapting speed however for unknown reason it later fails to start the process of slowing down and collision alarm is sounded symptom 2: vehicle bmw is tracking another vehicle and adapting speed on lane 1; upon bmw switching lanes to another clear lane the car accelerates to reach target speed and though it detects another vehicle in front it fails to start slowing down. Driver intervention is required to brake and slow down. Symptom 3: same as driving condition in symptom 2 except that upon lane switch the bmw fails completely to detect a vehicle parked in the second lane and keep going on at same speed. Driver intervention is required to stop the bmw i have videos of the three symptoms and ask you for means to upload the videos. Bmw dealership attempted to download new software to fix the problem but the problems increased. I have videos recorded post the repairs and would like to share with you. *tr
Due to rain in san diego, the bmw 740i intake at the bottom of the front bumper injested water in a normal driving situation and the motor exploded.
