How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

If the torque converter is broken, or if there is a low fluid level in the transmission, the converter will not do its job, and the car will be unable to maintain power at low speeds, which causes the engine to shut off.
The most common reasons a Nissan Pathfinder engine stalling are the fuel system, the air intake system, or the ignition system. Search our network of RepairPal Certified shops near you to speak with a technician about your issue. Oops! We got lost!
If your vehicle is only hard to steer when you first turn it on, then you likely have a damaged steering rack. Often this problem will go away when the car warms up, and the rack becomes hot and well lubricated.
The most common reasons a Nissan Pathfinder won`t start are a dead battery, an alternator problem, or failed starter.
The most likely issue is a clogged fuel filter. The purpose of the fuel filter is to ensure that dirt and debris stay out of the fuel system, so over time, it may need cleaned or replaced. When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive.
Alternator Issues

The alternator helps to manage the supply of electricity by recharging the battery. When there is a bad alternator, your car will shut off while driving. This primarily happens as it affects the power supply. Alternator issues will make the engine lose power.

If your car stalls, then it means the engine has stopped working for any number of reasons. This can be the result of a mechanical issue or a problem with the air or fuel the car is receiving. Your car can stall in pretty much any situation. It might stall shortly after you`ve started it up or while you`re driving.
The most common cause of a stiff steering wheel is when you are running low on power steering fluid in your system. Often, this happens when there is a leak in the system from the pressurized hose area. Most of the time, it is due to a cracked or loose hose causing the fluid to leak out.
Improper Fluid Levels

Too much and your valves and seals could collapse under the pressure. Not enough and the fluid can`t exert the force needed to turn your car. Replacing your fluid on time will help prevent this issue, but any leaks can cause a loss of fluid that will ultimately lead to power steering failure.

If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you`re dealing with a battery or an alternator problem. Here`s how to know which one is the culprit.
Flat or faulty car battery

A flat battery is the most common reason your car won`t start and can be caused by a number of things, such as lights being left on, something in the electrical system causing a battery drain, or even a faulty battery that won`t hold its charge.

Make sure you pair your device with the audio system first, and you should see your car appear on the list. If you still can`t find your car`s Bluetooth in there, the car`s and phone`s Bluetooth versions might be incompatible, the devices might be too far apart, or the car/phone is already connected to another device.
Some of the most common sensors that lead to engine stalling include the mass airflow sensor (MAF), engine coolant temperature sensor (ECT) and manifold absolute pressure sesnsor (MAP). The idle air control valve (IAC) and exhaust gas recirculation valve (EGR) are also well known for causing engine stalling.
If your car`s transmission has an internal pressure problem, it can cause the torque converter to lock up, causing your car to stall. Though not as often the culprit of engine stalling than others, the transmission shouldn`t be overlooked when searching for the root cause.
Faulty spark plugs can cause the car to exhibit starting troubles. Worn out plugs does not produce sufficient sparks, which is needed for starting the engine. This results in the engine to stall and fail to start quickly.
Number 1 – Bad Battery

A bad battery is one of the most common reasons that cars stall. Most people think that if a battery is dead, the car won`t start. Truth is, if your battery is going bad,your car will run but you`re at risk of stalling out.

If the engine stalls while idling or driving, the engine may be running out of fuel or not receiving enough fuel pressure to keep it running. The most likely cause of this kind of stalling would be a fuel pump that is not spinning fast enough or is intermittently cutting out.

When your transmission doesn`t have enough fluid, you may experience it stalling at red lights or stop signs. Though it should start right back up, taking your car to an auto shop for repair is key as your transmission lines may be leaking and may need to be replaced.

One of the most common problems power steering systems have is leaks. The high pressure of the system combined with the soft hoses carrying the fluid makes it relatively susceptible to leaks. A low fluid level can cause a whining power steering pump and even a loss of fluid pressure and a loss of steering assistance.
Once the battery is depleted, the vehicle will die and fail to restart. It is also important to note that if you drive a car with a bad or dead alternator, you run the risk of damaging critical electrical components such as the water pump, power steering, and fuel pump.
Bad Sensors

One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.

Connect your phone

Plug a USB cable into your vehicle`s USB port and plug the other end of the cable into your Android phone. Your phone might ask you to download the Android Auto app or update to the newest version of the app. Follow the on-screen instructions to complete setup.

The most common reason a pump fails is wear on the pump from improper lubrication or over-use. The best way to explain a failed fuel pump due to wear and tear is to explain what other reasons may have lead to a failed pump: Most fuel pumps are lubricated by the fuel in the tank itself.

Drive belt loose and power steering not working.
ANSWER : Hello, thank you for writing in. The vehicle’s drive belt is kept tight with an "auto-tensioner". This may be the pulley that has "popped" and released the tension. If that was the case, you would likely notice more issues than just the steering going out. The power steering pulley should still be inspected. If the vehicle runs, turn it on and watch the belt to see if anything is obviously wrong. Be careful, if the belt comes off or breaks it will fly off. The power steering pump pulley itself should not move. When the issue if found and corrected, make sure you replace the belt as well. Start by checking the auto-tensioner, and work your way to the power steering system.

I had a warning message in my 2013 Ford Fusion that the power steering assist failed. I have power steering capability now. Is it safe to drive?

power steering fluid is leaking
ANSWER : With a power steering fluid leak that big, you certainly should have the vehicle inspected as soon as possible to find the exact cause. Any of the components you listed can be the source of the leak. The power steering pump as well as the rack & pinion steering unit rely on the fluid for lubrication as well as cooling. The whining you hear is from the pump when the fluid runs low or empty. Your issue can be caused by something as simple as a fluid hose right now, but continued ’running dry" of the power steering fluid, can result in damage to both the pump and the rack & pinion unit. If that happens, you can take what may be a repair of a few hundred dollars and turn it into a repair of a couple of thousand dollars.

Loss of electrical power while driving but engine still works.
ANSWER : Check the battery on the vehicle and see if it is holding a charge. If the battery have a charge, then check the battery for a load. If the battery cannot hold a load, then the battery needs replaced. Check for any loose ground wiring from the cab to the chassis frame and see if they are corroded, damaged, or loose. A bad battery or a loose wire can cause electrical issues within the vehicle. If you need further assistance with your vehicle not starting due to an electrical issue, then seek out a professional, such as one from Your Mechanic, to help you.

Power steering pump on 2012 Acura TL needs to be replaced. Due to location a power bar also needs to be replaced. Cost over $3,000. Is this a good price?
ANSWER : Question sent to CS for a quote on replacing the power steering motor, programming, and replacing an electrical component attached to the motor. This is in comparison to a quote that was given for the parts and labor.

Why does my power steering only work when it wants to?
ANSWER : First off, I would not drive the vehicle until the problem is rectified, as this is a very unsafe driving condition.

I would have a certified mechanic take a look at the vehicle to diagnose the issue. With that said, they will also want to take a look at the intermediate shaft. It is a shaft that connects the steering wheel (column) to the rack and pinion (steering gear).

It has been my experience that this intermediate shaft will corrode over time and create a feeling of a loss of power steering assist. This is a situation where an experienced mechanic can perform some tests to identify if this is the problem.
