Engine tapping/knocking on first drive of day. 8 service visits. Service by BMW confirmed "noise is not normal." Escalated to BMW na 3 times. First serviced under BMW original warranty. BMW claims just a noisy engine by design. Even though BMW claimed it was normal, BMW could not tell me what it was or coming from. BMW is not compliant in performing under the new car warranty.
