Car rental problems are not evenly distributed. Some destinations generate significantly more post-rental charge disputes than others — because of the operators present, the local regulatory environment, and the specific practices that have developed in those markets.

This guide summarises the patterns CarRentalHelp has identified in each of the most common rental destinations, based on analysis of more than 12,000 publicly reported complaints. It is designed to help you understand what to expect — and what to document carefully — before and during a rental in each country.

⚠  This guide describes problem patterns, not typical experiences.

     The data reflects complaints from customers who experienced significant issues.

     Industry evidence suggests complaint rates represent 1–2% of total rentals.

     Most rentals in all destinations are completed without financial disputes.

Spain

Spain generates the highest volume of car rental complaints in the CarRentalHelp dataset by a considerable margin. Problems are concentrated at airport locations, particularly Malaga, Alicante, Palma, Barcelona and Ibiza.

▌  Primary issues: Post-rental damage charges (72–78% of problem cases), insurance pressure at the desk, deposit held as a sale rather than a pre-authorisation, and payment method restrictions used to force insurance purchases.

▌  What to document carefully: Photograph the entire vehicle at collection and return. Bring written evidence of any existing insurance cover. If possible, use a credit card with a known high limit to avoid deposit pre-authorisation problems.

▌  After-hours returns: Spanish airport locations are particularly associated with damage discovered after unstaffed returns. If possible, return during staffed hours and request written confirmation of the vehicle’s condition.

✔  Key practical tip: Arriving with a printed copy of your existing insurance policy and booking confirmation significantly reduces the risk of successful desk pressure.

Italy

Italy is the second highest-complaint destination in the dataset. Problems are concentrated at Rome Fiumicino, Bergamo (Orio al Serio), Catania, Venice and Milan airports.

▌  Primary issues: Damage charges in 75% of problem cases at the highest-complaint Italian operator, often for damage discovered hours after return. Insurance rejection and pressure-selling. Signature forgery allegations on return documents.

▌  Documented pattern: Several customers report being asked to show their photographs at return before the agent identified which damage to charge for — suggesting a process of locating areas not covered by customer photography.

▌  After-hours returns: After-hours returns at Italian airports are particularly associated with damage charges, because no staff member is present at car return. The charge is then applied before the customer is back in their home country.

✔  Key practical tip: Record a detailed video at both collection and return. If returning out of hours, send an email to the company immediately after drop-off confirming the time and condition of the vehicle.

Portugal

Portugal generates moderate complaint volumes with patterns similar to Spain. Faro Airport (serving the Algarve) is the primary problem location. Lisbon and Porto show lower complaint concentrations.

▌  Primary issues: Insurance pressure at the desk, deposit delays and partial retentions, and post-rental damage charges. Fuel policy disputes at Faro are also documented. Toll charges can be confusing.

▌  Positive exception: Several specialist brokers operating primarily in Portugal show very high customer satisfaction rates, with comprehensive insurance included and no post-rental charge issues. Pre-booking with a reputable specialist significantly reduces risk.

✔  Key practical tip: Faro Airport rental desks are particularly busy during summer peak periods. Allow more time than expected for collection, and do not rush the inspection process.

Greece

Greece shows similar patterns to Spain and Italy, concentrated at island airport locations including Corfu, Rhodes, Heraklion (Crete) and Kos.

▌  Primary issues: Insurance pressure, deposit handling problems, and post-rental damage charges. Vehicle quality complaints are more common in Greece than in other destinations in the dataset.

▌  Island-specific issue: On Greek islands, some operators have limited vehicle fleets and high seasonal demand. Reserved vehicle unavailability — and pressure to accept a paid upgrade — is more frequently reported here than in mainland European destinations.

✔  Key practical tip: Photograph any existing damage extremely thoroughly, including minor marks. On islands with limited transport alternatives, customers are in a weaker negotiating position at the desk.

France

France generates lower complaint volumes than Spain or Italy from rental companies directly but has a significant concentration of complaints associated with rental brokers operating at French regional airports.

▌  Primary issues: Post-rental charges including cleaning fees, damage claims and administrative fees. One car rental company operating primarily at Bordeaux, Lyon and Marseille airports shows 95% negative review rates in the dataset — the highest single-company rate recorded.

✔  Key practical tip: If renting at a French regional airport through a lesser-known operator, research the specific company — not just the broker — before travel.

United States

The United States generates different types of complaint from European destinations. Insurance-related disputes are particularly common because of the complexity of US rental insurance requirements and the high cost of collision cover.

▌  Primary issues: Unexpected insurance charges added at the desk, toll and electronic fee disputes (particularly involving          E-ZPass or similar systems), and administrative fees significantly exceeding the underlying charge.

▌  Debit card restrictions: US rental companies commonly decline debit cards for security deposits, requiring a credit card. This is more consistently enforced than in European markets and is generally disclosed in advance — but still catches some customers by surprise.

✔  Key practical tip: If your credit card includes car rental collision cover as a benefit, bring written confirmation. US rental desks routinely pressure customers to purchase additional CDW, even where card cover is in place.

Malta and Canary Islands

These island destinations are worth noting separately because of their particular rental market characteristics. Both show higher-than-average complaint rates relative to their size.

▌  Malta: Local operators dominate the market. Damage charges and deposit handling issues are the primary complaint types. Limited public transport alternatives create a captive market at the desk.

▌  Canary Islands (Lanzarote, Fuerteventura, Tenerife, Gran Canaria): Similar patterns to mainland Spain. Lanzarote in particular shows high complaint concentrations. Road surfaces on the islands mean vehicle damage from potholes and terrain is more common — creating additional ambiguity about damage origin.

✔  Key practical tip for both destinations: Document the tyre and alloy wheel condition extremely carefully at collection. Tyre and wheel damage is a frequent charge category in island markets with poorer road surfaces.

What applies in every country

Regardless of the destination, three principles from the dataset hold consistently.

▌  The airport premium

     Airport locations generate significantly higher complaint rates than city centre or port locations for the same operators. Airport arrivals involve time pressure, tiredness and limited alternatives - conditions that favour desk pressure tactics.

▌  The insurance correlation

     Across every country in the dataset, customers who purchase the operator’s own excess insurance at the desk report fewer post-rental problems than those who decline. This pattern is consistent enough to be significant regardless of destination.

▌  The documentation gap

     The customers who successfully challenge post-rental charges in every market share one thing: systematic photographic evidence taken at collection and return. This single practice reduces the risk of an unchallengeable damage charge more than any other.
