On the 2015-2020 Acura TLX, the dual-screen infotainment system in first-generation TLX models suffers from severe lag, random freezes, and full system crashes requiring a restart.

Common Symptoms

Touchscreen unresponsive or extremely laggy
System reboots while driving
Bluetooth audio cuts out
Backup camera black screen
Navigation screen freezes mid-route

How to Fix

Update infotainment firmware to the latest version via USB or dealer update. If freezing persists after the update, the head unit may need replacement with the revised hardware. Performing a factory reset can temporarily resolve lag but the issue typically returns.

On the 2018-2025 Acura TLX, tLX models equipped with the A-Spec or Type S brake package experience persistent brake squeal during light braking and premature inner pad wear on the front calipers. The sport-oriented pad compound generates significant noise at low speeds, and the sliding caliper pins seize from corrosion in regions with road salt.

This issue also affects: Acura ILX

Common Symptoms

High-pitched squeal during light braking
Inner pad wearing faster than outer pad
Grinding noise after rain or car wash
Brake dust buildup heavier on one wheel

How to Fix

Clean and re-lubricate the caliper slide pins with high-temperature silicone grease. Replace the OEM pads with a ceramic compound pad that offers similar performance with less noise. Apply anti-squeal shims if missing from the factory. Inspect and replace caliper bracket hardware if corroded.

What Owners Are Using

Parts and tips from 780+ owners who fixed this issue

TipApply CRC Disc Brake Quiet to the back of the pads and lube the slide pins every brake job. The A-Spec calipers are identical to standard but the pad compound is more aggressive.

Typical repair cost:$150 - $500
