The infotainment screen in my Acura TLX freezes frequently. What can be done?

Frozen or slow infotainment screens in TLX models (2015-2020) are a well-known frustration. Often, this is a software glitch rather than a hardware failure. The first step is to check for a system software update at your dealer or specialist shop. These updates frequently include fixes for screen freezing and audio glitches. If the screen remains unresponsive even after a software update, the issue could be with the audio unit or the display itself. We can diagnose the system, perform the updates, and advise if any hardware replacement is necessary to get your infotainment system working flawlessly again.

Why is my Acura's air conditioning blowing warm air, and what's the fix?

A warm A/C system can have several causes. In TSX models (2004-2014), for instance, the A/C compressor is a common failure point. Other common causes include a refrigerant leak (often from the condenser or a line), a failed compressor clutch relay, or a faulty expansion valve. At Westco Automotive, we perform a complete A/C performance test, checking pressures, inspecting for leaks with an electronic detector and UV dye, and testing all electrical components. This systematic approach ensures we correctly identify the root cause and perform the necessary repair, whether it's a simple recharge or a compressor replacement.

What is the P-AWS system on my Acura RLX, and why does it need calibration?

P-AWS stands for Precision All-Wheel Steer. It's a sophisticated system that independently steers the rear wheels to improve handling, stability, and maneuverability. The system relies on precise electronic control and sensors to determine when and how much to steer the rear wheels. If you've had a wheel alignment, suspension work, or if the system gets a warning light, a P-AWS calibration is required. This procedure uses a special diagnostic tool to reset the steering angle sensors and re-teach the system its parameters, ensuring it operates correctly. Attempting to align a P-AWS-equipped RLX without performing this calibration will result in improper handling.

When should I replace the timing belt on my Acura?

For Acura V6 engines (found in models like the TL, MDX, RLX, and certain TSX models), replacement is critical every 7 years or 105,000 miles, whichever comes first. This is not a suggestion—it's an engineering requirement. The timing belt is a rubber component that wears over time. If it breaks while the engine is running, the pistons will strike the valves, causing catastrophic and expensive engine damage. We always recommend replacing the water pump at the same time, as it's driven by the same belt and has a similar service life. This proactive approach saves you labor costs in the long run and gives you complete peace of mind.

Why is my Acura TLX transmission shifting roughly, especially from 2nd to 1st?

Rough shifting, particularly in early TLX models (2015-2020) equipped with the 8-speed dual-clutch transmission, is a known characteristic. This often manifests as a jerky or hesitant feeling when downshifting. In many cases, a transmission control module software update from Acura resolves this issue by refining the shift logic. However, it's also essential to ensure the transmission fluid is clean and at the correct level. At Westco Automotive, we start with a full diagnostic scan to check for any stored codes, then perform the necessary software update and fluid service to restore smooth, seamless shifts.

What causes the "VTC actuator rattle" on cold starts in my Acura RDX?

The VTC (Variable Timing Control) actuator rattle is a common issue in RDX models from 2013-2018. You'll hear a brief, grinding or rattling noise for one to two seconds when you start the engine cold, especially after it has sat overnight. This occurs because the actuator, which adjusts camshaft timing, loses oil pressure while the engine is off. When you start the car, it takes a moment for oil pressure to build and properly engage the actuator locking pin. Over time, this can wear the mechanism. Replacing the VTC actuator is the definitive fix, and we always recommend addressing it promptly to prevent potential timing chain issues down the road.

How often should I service my Acura's SH-AWD differential?

The Super Handling All-Wheel Drive (SH-AWD) system is a sophisticated feature that requires regular maintenance. While your Acura's maintenance minder system will alert you, we generally recommend a differential fluid service every 30,000 to 50,000 miles, depending on your driving habits. This involves draining the old, contaminated fluid and refilling it with the correct Honda/Acura-spec fluid. Regular changes prevent premature wear, keep the system operating quietly, and ensure you have maximum traction in Colorado Springs' unpredictable weather.

My Acura MDX has a "torque converter shudder." What does that mean?

A torque converter shudder feels like a vibration or shaking, often felt under light acceleration at highway speeds (around 35-45 mph). In MDX models from 2007-2013, this is a known issue. The root cause is often related to the torque converter clutch not engaging smoothly. In some cases, a specialized transmission fluid flush and a software update can remedy the condition. However, if the shudder has been present for a long time, the torque converter itself may need to be replaced. We diagnose this with a comprehensive road test and transmission analysis to determine the most cost-effective solution for your MDX.

Is carbon cleaning really necessary for my direct-injection Acura engine?

Yes, it's a vital maintenance item for direct-injection engines, which are common in many modern Acura models. Unlike port-injection systems where fuel cleans the intake valves, direct-injection engines spray fuel directly into the cylinder, leaving the intake valves exposed to oil and crankcase vapors. Over time, this creates hard carbon deposits. This can lead to rough idling, reduced fuel economy, hesitation, and even misfires. A professional carbon cleaning service, such as a walnut blast or chemical induction service, thoroughly cleans the intake valves and restores optimal engine performance. We recommend this service typically between 60,000 and 80,000 miles.

Why does the navigation screen on my Acura TL or MDX look like it's peeling?

This is a common issue known as "screen delamination," frequently seen in older TL (2009-2014) and MDX (2007-2013) models. The issue is caused by the adhesive bonding the touchscreen layers degrading over time due to heat and UV exposure. This can result in a cloudy, bubbly, or cracked appearance, and it can also make the touchscreen unresponsive. Unfortunately, there is no repair for the screen itself; the solution is to replace the entire navigation display unit. We use high-quality replacement units to restore full functionality and appearance.
