Acura RL has always been in the shadow, enjoying its anonymity. However, despite almost unimpressive features, sales are still amusingly intact and the model still remains in production. However, Acura is currently doing major improvements to the RL. And since the model has not unleashed its full potential yet, there are some common problems in some Acura RL parts that current owners encounter.
All vehicles in general encounter issues with the suspension system, and Acura RL is no exclusion from that. The common suspension problem with the Acura RL suspension system is the lower ball joints and control arms. Since these parts are always subject to abuse each and every ride, they are prone to corrosion and damage. They are also the ones that support the car body when driving, so worn suspension parts should be replaced immediately.
In the year 1998, Acura did a recall of the lower ball joints and control arms, replacing these parts for approximately 124,875 units.
Needless to say, the braking system of Acura RL is a very important component of the vehicle. It is the most important safety feature an automobile can have. Unfortunately, the RL is not immune to problems with the braking system. A common one is with the brake stop switch. This switch often leaks, exposing different internal parts with brake fluids that may contaminate them. This may result in malfunctions of various parts.
In 2002, Acura made a recall for this particular issue where 25,765 units were affected. The dealers did free cleaning of the internal parts and replaced the brake stop switch with a new and more durable one.
The coil wire that can be seen in relay of the fuel pump is not one of the Acura RL accessories. It helps in delivering fuel to the engine body. This particular part has the tendency to break, reducing the power of the fuel pump to the point where it no longer delivers fuel when needed to. The bad thing about it is that the vehicle can stop without any warning if things get worse. This may cause serious road accidents.
This is precisely why in 2007, Acura made a recall of the coil wire to 166,561 affected units. In this particular recall, Acura dealers inspected the fuel pump and replaced the whole relay if problems were detected.
