Let's dive deep into the reliability of the 2005 Acura RL SH-AWD. When you're considering a used car, especially a luxury sedan from the mid-2000s, reliability is usually at the top of your list. The 2005 Acura RL, equipped with Super Handling All-Wheel Drive (SH-AWD), was designed to offer a blend of luxury, performance, and advanced technology. But how well does it hold up over time? This is the million-dollar question, right? Well, let’s break it down. The Acura RL, particularly the 2005 model with SH-AWD, generally enjoys a good reputation for reliability, but like any car, it has its quirks. Owners often praise its smooth ride, comfortable interior, and the impressive grip provided by the SH-AWD system, especially in challenging weather conditions. However, potential buyers should be aware of some common issues that can affect the car's long-term dependability. One area to pay close attention to is the car's electronic systems.

Keep an eye out for any signs of transmission slippage or rough shifting, as these could indicate underlying issues. Suspension components, such as shocks, struts, and control arms, can also wear out over time, affecting the car's ride quality and handling. Replacing these components can restore the car's original driving dynamics, but it's an expense to consider. Rust can also be a concern, especially in areas with harsh winters or salty roads. Inspect the car's undercarriage, rocker panels, and other susceptible areas for any signs of corrosion. Addressing rust early can prevent it from spreading and causing more extensive damage. Overall, the 2005 Acura RL SH-AWD can be a reliable car if properly maintained and cared for. Be sure to have any used RL thoroughly inspected by a qualified mechanic before making a purchase, and factor in the cost of potential repairs and maintenance when evaluating its overall value.

Common Issues and Problem Areas

Okay, guys, let's talk about the nitty-gritty – the common issues and problem areas you might encounter with a 2005 Acura RL SH-AWD.
