What 2020 BMW X4 owners say
Electrical system
I own the car since brand new from dealership and never have incident. Couple weeks ago, started having issues with digital main instruments panel. Suddenly when I turn on the car in the morning the dash simply does not work. I got alert saying one the safety system is malfunctioning but not say what it was specifically. After 5 min the engine is on the main dash back to work normally, and all the alerts disappear. I have checked faulty codes and I see faulty code record to identify what would be. I would report as safety incident as the failure is Randon and sometimes happen when I park the car in the office or anytime and I have to drive with no panel instruments working back to home. I have taken the bar back to dealership for investigation and they want to charge me $180 USD just for diagnose as it's out of warranty. …

Air bags
The contact owns a 2020 BMW X4. The contact stated that while driving at an undisclosed speed, the "Restrain System Fault" message was displayed. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the driver's side seat belt. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 20V164000 (Seat Belt, Air Bags) but the VIN was not included. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 42,000.
On June 21, 2020, on a city street. My white BMW was traveling westward and a black BMW was traveling southbound. The black BMW ran its red light to my green light. When we collided in the intersection the complete front end of my white BMW impacted the black BMW driver's side, from approximately from the front tire, to just into its rear door. That impact caused the black BMW's side airbags to deploy, and either at the same time or upon a subsequent collision with a bollard, its front airbags deployed also. To my shock and dismay, non of the airbags in my white BMW deployed,. All airbags are still in their respective storage compartments. Additionally, I have highlighted several other standard safety features of the car that did not perform its designated function either. I would like you to investigate why these systems failed me. Thank you
Suspension
I am filing a complaint regarding what I believe is a manufacturer defect in my BMW vehicle. During a recent visit to an authorized BMW dealership for a routine oil change, I was informed that the front tension joints (tension struts) must be replaced because the rubber bushings/gaskets are cracked and leaking fluid. My vehicle has fewer than 33,000 miles, and I drive infrequently. This was missed during the last oil change which was 6-8k miles ago. This type of failure at such low mileage is unreasonable and inconsistent with normal wear and tear. The dealership quoted approximately $1,800 plus tax, not sure if it includes a required wheel alignment, to repair the issue. BMW has declined responsibility and stated the damage could caused by road conditions. …

It is very dangerous for me to drive because in a snow or rainy day it very slippery and sometime I almost cash because slip indicators turn on .
