Purchased brand new as a demo model in August 1996, our ’96 E320 Mercedes has been a member of the family for years. Initially, everything about the car was appealing, embodying the luxury and performance expected from Mercedes-Benz. However, over time, durability has become a significant concern, contrasting sharply with the initial positive impressions. With 63,000 miles on the odometer and a consistent dealer service history according to schedule, the expectation was for robust reliability. Driven primarily by my wife for a short daily commute of approximately half a mile, the car has never endured hard or aggressive driving. Despite this gentle use and meticulous maintenance, a series of recurring issues have emerged, painting a picture of less-than-stellar long-term dependability for this particular 1996 E320 Mercedes.
Recurring Window Regulator Failures
One of the most persistent issues has been with the window regulators. Within a single month, two regulators failed. While the dealership initially covered the second failure under warranty after some negotiation, the first repair was an out-of-pocket expense. Now, the left rear window regulator has failed again, prompting a decision to undertake a DIY repair, leveraging online resources for guidance. This repeated failure of window regulators highlights a potential weakness in the build quality or components of the 1996 E320 Mercedes.
Air Conditioning and Cooling System Setbacks
The air conditioning system also presented significant problems. At 56,000 miles, the A/C ceased functioning. Although the dealership had noted potential issues as early as 40,000 miles, they were unable to pinpoint the problem until it worsened. Eventually, the repair was performed under warranty. However, the A/C system failed again at 62,000 miles, resulting in a substantial $900 repair bill. Furthermore, a head gasket issue surfaced at 48,000 miles. Despite the car being five years old at that point, warranty coverage was again secured for this major repair. These repeated and significant failures within the climate control and engine cooling systems raise concerns about the longevity and reliability of these critical components in the 1996 E320 Mercedes.
Door Lock and Security System Malfunctions
The central locking system has become another area of concern. None of the door locks are currently operational. The auto infra-red locking system has also broken down, and despite dealer attempts, a resolution was not found, leaving this feature unrepaired. Compounding the issue, the driver’s side door lock is also broken. Consequently, accessing and securing the vehicle now relies solely on the trunk lock. This widespread failure of the door locking mechanisms not only presents an inconvenience but also raises security concerns regarding the 1996 E320 Mercedes.
Additional Mechanical and Electrical Issues
Beyond these major systems, other components have also exhibited premature wear or failure. The turn indicator dimmer stalk broke and while a $900 dealer repair was quoted, a more pragmatic approach of regular super glue fixes every three months has been adopted. The radio also presented a problem when the security code was lost after a battery replacement. The current code requires the number 6, but the number 6 button on the radio is non-functional, rendering the radio unusable. Currently, several items are in need of repair, including the auxiliary cooling fan controller, mass airflow indicator, left rear window regulator (again), a new radio, and the auto door locks, as previously mentioned, along with the driver’s door lock. The estimated repair cost from the dealer for the items excluding the window regulator and locks is $2,800, highlighting the escalating maintenance costs associated with this 1996 E320 Mercedes.
Paint and Interior Deterioration
Cosmetic and interior elements have also shown signs of deterioration. The Black Opal paint, while initially striking, has significantly deteriorated on the roof rails, roof, and trunk deck. This deterioration manifests as fading to white and severe orange peel, despite regular waxing. Minor rust has also appeared where the license plate housing and trunk meet, attributed to a sticky rubber seal around the trunk. Inside, the dashboard vinyl has cracked. While it was replaced once under warranty at 36,000 miles, it has cracked again at 48,000 miles, and further warranty replacement was denied. These paint and interior issues detract from the overall appearance and perceived quality of the 1996 E320 Mercedes, particularly given its age and mileage.
Conclusion: A Mixed Ownership Experience
In conclusion, while the 1996 E320 Mercedes initially presented as a luxurious and well-engineered vehicle, long-term ownership has revealed significant concerns regarding durability and reliability. Despite regular dealer servicing and gentle driving conditions, a range of mechanical, electrical, and cosmetic issues have emerged, leading to recurring repairs and escalating maintenance costs. From persistent window regulator failures and air conditioning problems to door lock malfunctions and paint deterioration, the ownership experience has been marred by a series of unexpected setbacks. For potential buyers of a used 1996 E320 Mercedes, this owner’s experience serves as a cautionary tale, highlighting the importance of thorough pre-purchase inspections and an awareness of potential reliability issues that may arise with this model over time.
