Experienced mechanics share their insights in answering this question :
Although the most common problem for the wipers on this vehicle is the wiper motor, I’m not so certain this is the case for you. I believe you may have a bad ground somewhere under the dash.

Dirty Windscreen

Arguably one of the most common causes of a squeaky windscreen is dirty glass. This is when debris, like particles of dirt or sand, gather on the windscreen`s glass. As a result, this can be the primary cause for the unwanted squeaking noise.

There are a number of reasons why windscreen wipers stop working and these include: torn wipers, broken controls, a blown fuse, faults with the motor, damaged arms, snow or ice covering, loose pivot nuts and a break in the wires. Torn wipers – wiper blades are comprised of plastic with rubber attachments.
Bad wiring: Faulty connections or loose wiring can result in windshield wipers running even when you turn them off. Broken controls: The windshield wiper switch inside your car gets plenty of use, so it can fail internally and cause the wipers to stay on no matter what setting you choose.
One of the biggest reasons why wiper blades squeak is due to an accumulation of dirt and grime. This can be cleaned off with soapy water and an alcohol-based cleaner. Dip a rag or a piece of cloth in detergent, and wipe down the blades. Make sure to wipe the screws and hinged parts of the wiper as well.
Before the wiper motor goes bad, you will probably experience a blown wiper fuse, which is intentional. The fuse is designed to be the circuits weak spot, which protects the wiper motor. Essentially, if your vehicle`s wiper motor is being overloaded, the fuse will blow to ensure the motor does not become damaged.
The Windshield Wiper Motor Relay is a part of your windshield wiper system. It controls the voltage input to the wiper motor. The relay senses the position of the wipers and transmits power to the wipers they are in their parked position.
We don`t recommend using WD-40 on your windows or windshields but you can apply WD-40 Multi-Use to your number plate to not only provide a protective layer to stop it from rusting but to also prevent ice from sticking to it. The unique WD-40 formula repels water and can be used as a rust prevention spray.
Check the Fuse

With the car parked in a quiet place, operate the window washer and listen for the whirring of the pump. If there`s no sound, head right for the fuse box. If the fuse is blown, it`s usually a sign of a dead pump motor or one that`s ready to check out. If it blows again, replace the motor.

Windshield wiper clicks and engine revving heard on radio
ANSWER : Yes, corrosion on a ground terminal or splice point can cause various engine and electrical systems issues. Looking at the wiring diagrams I see nothing related between the entertainment and engine control systems that jump out at me as the cause. However, both of these systems are grounded to the chassis and a bad chassis ground could be the cause.

One way to check this would be to do a key on voltage drop test of the chassis to negative battery terminal. The voltage drop should be less than 0.1V. Anything higher than this reading would indicate resistance in the chassis ground system and all ground points should be checked for possible corrosion or looseness. You may want to enlist the help of a mechanic, such as one from YourMechanic, who will have the tools and expertise to diagnose your radio problem and starting issue.

Intermittent Windshield Wipers move 1/4 of the way
ANSWER : Your windshield wiper motor controller is not able to control the motor to bring it to the park position. The problem is in the wiper motor most likely or the body control module since you have same issue with the rear wiper also. Sine you are under basic warranty I would suggest having the dealer check to see if it is a covered repair. If not then a mechanic like one from YourMechanic can check and do the repairs for you.

Car was working fine before but now bothing turns on at all, and no noise. Key remote also won’t un/lock car at all
ANSWER : Give the shifter a good wiggle forwards and backwards. If it starts after doing that, you may have issues with the shifter interlock or the shifter cable itself. If the shifter cable is loose or worn, it may not be allowing the shifter to be fully in park and causing issues with the ignition. If this does nothing to get the vehicle to start, then the ignition switch and/or ignition lock cylinder themselves may be at fault. The ignition lock cylinder car wear over time, as can the key(s). Try another key if you have one. If that doesn’t help, a new ignition with new keys may be the answer.

Drove car, stopped, tried to restart and no sound.
