Experienced mechanics share their insights in answering this question :
Hey there. This is a common issue on the Cadillac DTS and is often times linked to the CV joints and axle boots. Check the rubber boots for these to be sure they are not torn or full of dirt. Also check to be sure they are greased well.

It sounds like the car was only inspected while not in motion. You will probably want to have the next mechanic run the car in the exact same conditions that you hear the symptoms in order to have this properly diagnosed. If you would like to have another expert take a look, a certified technician from YourMechanic can come to your car’s location to test the car and diagnose the clicking sound.

A CV axle can typically be expected to last for 80,000 to 100,000 miles under normal driving conditions. You`ll know when the axle is about to fail when you begin to hear a loud, rhythmic clicking noise coming from the front wheel as you turn. That noise is due to a lack of lubricant in one of the CV joints.
If you hear your vehicle`s engine making clicking sounds as it is running, then there may not be enough oil in the engine. When an engine`s oil level is too low, its components will click as a result of not being adequately lubricated.
If you hear a clicking or popping sound coming from your wheels, chances are, it isn`t actually your wheels making those noises but your suspension or drive system. The most common cause of these sounds is damaged and dying CV joints.
Clicking/Popping/Clunking.

You can drive on a damaged CV joint for a little while, but there`s no telling how long “safe” operation will last. There are many factors, such as where you drive, the amount of dirt/dust/debris in the areas you drive, how much water gets into the joint, and more.

One of the most common causes is worn-out ball joints. Ball joints connect the control arm to the steering knuckle and allow the car to turn. When they wear out, they can cause a clicking noise.
There is most likely nothing wrong with the replacement shock or strut, but a metallic clunking noise typically indicates loose or worn mounting hardware. A loose mount can allow movement between the bolt and attaching parts, while a mount that is worn can cause the shock/strut to move up and down.
Popping or clicking noises when turning.

This indicates a worn or damaged outer CV joint. To verify this condition, place the vehicle in reverse, crank the steering wheel to one side and drive the vehicle backward in a circle (check the rearview mirror first!).

If the CV joint gets corrupted or contamination takes place, then the lubricant will leak. A boot seals the CV, and this boot is not resistant to damage. Whenever this happens, the joint will wear out and fail. If you drive a car with a damaged CV, the joint will deteriorate more, making driving impossible.
A worn outer CV joint will produce loud clicking noises when you turn sharply. Usually, this noise will increase with acceleration. A worn inner CV joint can cause loud clunking noises when switching between drive and reverse.

My 2003 ford explorer wont start up just get click click click click click click click click
ANSWER : If the battery is weak and the voltage is dropping to below 9 volts you will get the clicking without the starter turning the motor. Have the battery voltage checked and if battery cannot hold a load then replace it and clean the battery terminals and recheck system to see if it starts.

Metallic click sound when putting car in drive or reverse from park, and another click (sometimes) when making a turn.
ANSWER : You may have damaged the axle or strut. I would have the entire front inspected and have the clicking diagnosed. When anyone hits something hard enough to pop a tire there is most likely damage to some component in the area where it was hit. A visual inspection may or may not identify the problem, but a good mechanic can road test and hear the sound and should be able to pinpoint the cause of the clicking noise and recommend a repair.

2011 ford escape gear shift wont more from park to drive from time to time.
ANSWER : Hi there. The interlock solenoid in the shifter housing is not working and is causing the shifter to stay locked in the park position. This solenoid works with the brake switch. Check the brake switch and see if there is any loose connections. If the brake switch is working, then I recommend replacing the shifter interlock solenoid. If you need further assistance with your shifter issue, then seek out a professional, such as one from Your Mechanic, to help you.

Why does my brake warning light go on (for long period of time) and off (also for long period of time) while driving?
ANSWER : Hi there. The brake system Warning Light can illuminate for two reasons: First, the parking brake is currently engaged. Second, a component within the the brake system is malfunctioning. If the brake system Warning Light is illuminated, and the parking brake is released, then there is most likely an issue with the brake system, and the vehicle should be inspected as soon as possible. It’s probably a good idea to have a brake warning light inspection completed by a professional mobile mechanic so they can determine what’s causing these issues.

When shifting from reverse to drive or drive to reverse I hear a clicking noise.
ANSWER : Hi there. There is a gear train issue with your transmission or a bad CV Shaft that is causing the transmission to shift had into gear. Since it shifts harder in reverse than forward, I suggest that the gears inside the transmission are worn. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your transmission issue.
