Signs of a Rear Power Door Failure in an Infiniti in Birmingham
A rear power door is one of the most common features in SUVs today. At some point in time, most Infiniti drivers have found themselves facing rear power door failure. This problem makes it so the rear door is difficult to raise and sometimes becomes inoperable in cases of complete failure. When this happens, it’s advisable to contact a reliable mechanic to help you get to the root of the problem and fix it. Let’s have a look at some potential causes of power door failure in your Infiniti as well as symptoms that will point you to the problem below.
Signs of Rear Power Door Failure
There are some signs that you’ll notice in your Infiniti when the rear power door fails. The first sign would be that the power door will become erratic such that it will lock and unlock on impulse. You may also have a problem unlocking or locking the door and need to repeat a command before it follows through. This can be an inconvenience, especially if you’re in a rush and you need to access the cargo area and to put heavy items in or during inclimate weather. Electrical faults are the main culprit in erratic behavior in rear power doors.
You may also notice some strange noises coming from the rear power door. This could be because of motor faults. Rear power door motors often produce a quiet whir as they open and close. When the motors wear out and loosen up, the noise will become louder. If the motors aren’t repaired as soon as possible the noise will get louder until they eventually fail, and the power door will be unable to open and close.
Causes of Rear Power Door Failure
A rear power door is a hatch that opens and closes electronically either by the push of a button in the cabin of a car, on the hatch itself, or on the key fob. This means that when the rear power door has a fault, you may be unable to access or use the cargo area of your Infiniti, creating an inconvenience for you. For example, if you often use the cargo area for groceries or equipment, you may find yourself having to improvise to transport items from one point to another.
There are several potential reasons for rear power door failure but the one that stands out is electrical faults. The power door’s fuse may blow out, leaving no supply of power to pop the door open. This is an electrically-powered component when you use your fob or sensor, so it won’t work without power supply.
Another reason why it may fail is because if you use your key fob to operate it, the fob may be due for a battery change. This is easy to diagnose because a key fob that needs a battery change won’t lock or unlock all your other doors as well.
The position of the rear power door button under your Infiniti’s steering wheel may be yet another possible cause of failure. You may have inadvertently pushed the power down button with your knee and locked it up. You should ensure this button is in the correct position before concluding that the rear power door has failed.
In addition, another cause of rear power door failure is a faulty motor. This power door is operated by a number of motors going up and down to open and close it. These motors can sometimes wear out and stop working, especially if they don’t have proper lubrication. Lack of lubrication causes faster wear in the moving parts, causing even more wear and tear.
