Overview

• Consumer centers report a nationwide uptick in grievances tied to barrier‑free, license‑plate–monitored lots at supermarkets, medical sites and stations.
• Rheinland‑Pfalz logged 127 cases by early August 2025 after 109 in all of 2024, while the Hesse center counted roughly 30 since May.
• Common complaints cite unclear signage, steep contractual penalties, debt‑collection letters and poor customer service.
• A documented case in Hannover showed a machine displaying “0 euros” during a 15‑minute free period, followed by a €47 demand after the driver exceeded the exit time.
• Providers including Mobility Hub, Park & Control and Wemolo defend low violation rates as user‑error driven, while chains such as Lidl, Aldi Nord and Kaufland say they have adjusted or ended contracts and consumer advocates urge motorists to keep receipts and photograph signage.
