You may be responsible for damage charges upon return of your leased vehicle. Normal wear and tear is expected on a lease; however, the definition of normal can vary widely.
Make sure your lease agreement is specific with regard to dings, scratches, stains, upholstery damage, and tire wear. Tires are typically expected to be a matched set of four. All repairs must be performed with original equipment manufacturer parts, unless otherwise specified.
If you turn in your lease car with improper repairs, the lease company will typically charge you the cost to correct it. For example, a mismatched tire may result in the retail cost for four new tires—$1,000 to $2,000, depending on make and model.
