2004 Acura RL Problems
RepairPal has identified the most common problems with the 2004 Acura RL based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The 1999-2004 Acura RL has brake caliper issues, which are known for causing vibration and grinding noises at all times.
The brake rotor is a disk that sits between two brake pads. The brake pads are squeezed against the disk by what is called a brake caliper. When that caliper gets stuck, the brake pads are permanently pressed against the rotor causing:
The repair for a seized brake caliper, the brake pads, brake rotor, and brake caliper must be replaced or vibration will remain after the new caliper is installed. Changing the brake fluid and flushing the brake system according to manufacturer specified intervals can help improve longevity of the brake caliper.
The exhaust recirculation valve (EGR) on the 1996-2012 Acura RL may fail, causing:
The EGR valve has open and closed positions, and opens or closes on command from the computer.
Exhaust gases constantly pass through the valve when it is open, leaving carbon deposits on the valve. These carbon deposits may lead the the valve sticking in the open or closed position.
To correct this issue, sometimes it is sufficient to clean the valve, but replacement is recommended in all cases.

These relays send power to the fuel pump and fuel injectors when the key is turned to the “ON” position. So, when they fail, there is no electrical current to the necessary fuel system components to send fuel into the engine, causing engine stalling or failure to start.
In this situation, there are many other possibilities, so testing components is vital for time and money savings.
If the relays test bad, they must be replaced with relays specific for that circuit.
To help prolong the life of your under-hood electrical components, ensure the lid for the fuse block is closed, and any factory sealing material is correctly installed.
The starter motor used on the 1996-2006 Acura RL frequently fails on vehicles around 125,000 miles.
It may help prolong the life of the starter to service the starter to ensure the connections are clean and tight at the 100,000 mile mark.
Acura extended the warranty due to numerous issues with the automatic transmission. Problems with the automatic transmission may make the car undrivable and can result in costly repairs.
