Tl* the contact owns a 2019 bmw x4. the contact stated that the driver assistance package failed and the warning vibration when the contact almost crashed. the system was supposed to vibrate when and if the contact was about to crash. the contact stated that the package vibration signal was very low and the contact could not feel it activate. the vehicle was driven to kritz bmw savannah (7009 abercorn st, savannah, ga 31406, (912) 354-7000) where it was diagnosed that a new vibration motor and computer update were needed. the vehicle was repaired. the manufacturer was made aware of the failure and stated that they would escalate the incident. the failure mileage was 2,321. *bf the car was road tested after repair. dealer repairmen stated contacts vehicle and other x 4's on the lot performed the same. contact stated that the "repairs" did not improve vibration warning even when set on "strong" a vibration that can only be felt on a smooth road when the driver purposely crosses the lane markings is not a "warning" and is unsafe. the essence of my complaint is that the lane departure system while "working" is not providing a strong vibration that serves as a warning. the dealer states my vibration matches otherx4s and is therefore repaired. i feel all x4s are no not performing as designed and are therefore a safety hazzard. i purchased this car with this specific feature to assist my driving should i drift into the on coming lane without a sufficient vibration (warning) i feel the car is dangerous and someday there will be accidents due to this miss representation. my last car, a 2017 mercedes had a great lane departure system that really warned without a positive warning! the driver bmw has some how released this newly designed model.*jb
