DO NOT BUY USED FROM MERCEDES-BENZ OF ESCONDIDO — $15,700 OF CRITICAL MECHANICAL ISSUES FOUND 6 WEEKS AFTER PURCHASE
I purchased a used BMW X5 from Mercedes-Benz of Escondido on May 11, 2025. Less than 48 hours after driving it off the lot, I received my first engine oil warning. Since that time, the vehicle has been consuming approximately 2 quarts of oil every 1,000 miles, which is unacceptable for a car that was supposedly inspected and certified as roadworthy.
I brought it to BMW of San Diego for a diagnostic inspection on June 20, 2025.
Their findings were deeply concerning:
Transfer Case Malfunction & Worn Front Differential Driveshaft — $9,416.16
Upper Oil Pan Gasket Leak — $6,329.83
These repairs total $15,745.99 and were all flagged as requiring immediate action. These are not minor issues — they are critical drivetrain and oil system failures that should have been caught before the sale.
These findings directly contradict the multi-point inspection completed by Mercedes-Benz of Escondido before they sold the car to me. It is simply not plausible that all of these issues developed in the six weeks since purchase — especially when the oil warning began the day after I drove the car home.
As long as this review remains up, it means Mercedes-Benz of Escondido has not taken responsibility or addressed my concerns.
I urge any potential buyers to be cautious. This dealership sold me a vehicle with nearly $16,000 in immediate mechanical issues, and I am asking for some accountability. The dealership is absolutely gorgeous and the staff were very friendly and hospitable, however this experience has shown a clear failure in transparency, quality control, and customer protection.
