NHTSA's summary

"Steering Wheel Does Not Return to Center. INFORMATION Do not replace any parts for this complaint. The return behavior is inherent in the design of the EPS. Attention: An EPS ""break in"" period of approximately 2000 miles is required. Once this phase is completed, the level of friction is significantly reduced and no longer affects the return to center. Please use this information to educate the customer on the ""break in"" period of the EPS. If the customer complaint is still there after the ""break in"" period, program the vehicle with ISTA/P 3.59.0 or higher Target integration level: S15A-16-07-501 For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal / Service / Workshop Technology / Vehicle Programming. Always connect a BMW approved battery charger/power supply (SI B04 23 10). WARRANTY INFORMATION Covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks or the BMW Certified Pre-Owned Program. Defect Code: 32 13 02 "
