NHTSA Complaint #11698408 — 2025 VOLKSWAGEN TIGUAN

Started noticing issues within first week of purchase. Cruise control will not increase nor decrease speed when set. Steering wheel controls will not advance or decrease speed. Intermittent problem. First service dealer could not replicate. Second service dealer contacted VW assist and was advised to replace steering wheel buttons. Did not fix problem. Third service VW assist advised to replace clock spring and wiring harness. Part still on back order almost a month later. Meanwhile, vehicle now rapidly decreases or advances speed on own while cruise control is set. Adaptive control function is off and not source of issue. I feel this is software related issue as I have also had malfunction of infotainment radio system. Another reason I feel software issue is due to vehicle back up safety braking activates and throws vehicle into park when nothing is behind me.
