Addressing these proactively can prevent more significant and costly repairs down the line. * **Automatic Transmission Failure:** This is arguably the most well-known and significant issue for the 3rd generation TL, particularly the 2005 model. Owners often report symptoms such as: * **Rough or delayed shifting:** Especially noticeable between 2nd and 3rd gears, or during downshifts. * **Slipping:** The engine revs but the car doesn't accelerate proportionally. * **Complete failure:** Leading to the car becoming undrivable. The root cause is often attributed to internal wear, fluid degradation, and heat buildup. While Acura did extend warranties and issue recalls for earlier models, the 2005 TL still falls within the problematic range. Regular and specific transmission fluid changes are paramount (see maintenance section). * **Power Steering Pump Leaks & Whining:** A very common issue where the power steering pump develops leaks, often manifesting as a whining noise, especially during turns or when the car is cold. This leads to fluid loss, requiring frequent top-ups and eventually, pump replacement if not addressed. The O-ring and seals are often the culprits. * **Dashboard Cracking:** A widespread cosmetic issue, particularly in regions with hot climates or where the car is frequently exposed to direct sunlight. The dashboard material can develop cracks, especially around the passenger airbag area or near the windshield. While not a mechanical failure, it significantly detracts from the interior aesthetics. * **Motor Mount Failure:** The engine and transmission mounts are designed to absorb vibrations. Over time, these rubber components degrade and fail, leading to excessive engine vibration felt throughout the cabin, clunking noises during acceleration or braking, and potentially uneven engine wear. The rear motor mount is often the first to go. * **AC Compressor Failure:** Owners frequently report issues with the air conditioning system, specifically the AC compressor failing. Symptoms include a lack of cold air, a loud grinding or squealing noise when the AC is on, or the AC simply not engaging. This is a common wear item, but its failure can be costly. * **Starter Motor Issues:** As the car ages, the starter motor can wear out, leading to difficulty starting the vehicle. Symptoms include a clicking sound when turning the key, or the engine cranking slowly or not at all. * **Battery Drain (Parasitic Draw):** Some owners experience unexplained battery drain, where the battery dies overnight or after being parked for a few days. This can be challenging to diagnose, as it often involves tracking down a parasitic draw from a faulty electrical component, such as an aftermarket alarm, a malfunctioning relay, or even a faulty hands-free link (HFL) module. * **TPMS Sensor Failure:** The Tire Pressure Monitoring System (TPMS) sensors, located inside each wheel, have a finite lifespan (typically 7-10 years) due to their internal batteries. Failure results in a persistent warning light on the dashboard, requiring replacement of the sensors. ### Recalls for the 2005 Acura TL Recalls are issued by manufacturers to address safety defects or non-compliance with federal standards. It's crucial for any owner or prospective buyer to check for open recalls. For the 2005 Acura TL, the most prominent recall, affecting millions of vehicles across many brands, is: * **Takata Airbag Inflator Recall:** This widespread recall affects the driver and/or passenger front airbag inflators, which could rupture upon deployment, sending metal fragments into the cabin. This is a critical safety issue, and affected vehicles should have this recall addressed immediately by an Acura dealership, free of charge. While other minor recalls or service bulletins may have been issued over the years, the Takata airbag recall is the most significant. To determine if a specific 2005 Acura TL has any open recalls, it is essential to check its Vehicle Identification Number (VIN) on the NHTSA recall website or through an Acura dealership. ### 2005 Acura TL Reliability: What to Expect Despite the common problems listed above, the overall **ACURA TL reliability** for the 2005 model is generally considered good, especially when compared to some European luxury counterparts of the same era. The 3.2L J-series V6 engine itself is a remarkably robust and long-lasting unit, capable of reaching well over 200,000 miles with proper care. However, the Achilles' heel remains the automatic transmission. A 2005 TL with a well-documented history of regular transmission fluid changes, or one that has already had its transmission rebuilt or replaced, will undoubtedly be more reliable. Vehicles that have been neglected, particularly in terms of fluid maintenance, are more likely to exhibit the common issues. The TL's reliability is highly dependent on its maintenance history. A well-maintained 2005 TL can still provide years of dependable service, offering a comfortable and engaging driving experience. Conversely, a poorly maintained example can quickly become a money pit. ### Essential Maintenance Guide for Your 2005 Acura TL Proactive and diligent **ACURA TL maintenance** is the cornerstone of long-term reliability for the 2005 model. Following a strict maintenance schedule, often more rigorous than the factory recommendations for certain components, can mitigate many of the common issues. * **Engine Oil & Filter Changes:** * **Frequency:** Every 5,000-7,500 miles or every 6 months, using synthetic blend or full synthetic oil (5W-20). * **Importance:** Regular changes are vital for engine longevity, especially for a high-performance V6. * **Automatic Transmission Fluid (ATF) Changes:** * **Frequency:** This is critical.
