Stalling engine, brakes, power steering and transmission failure
The mileage on my car is around 104,000. The engine has been stalling, no matter what speed that I go. Along with the stalling, the brakes and power steering fail. My car also has transmission failure, which in my opinion is the cause of the stalling. When I shift into park, then my car will restart normally. The dealership told me that they could not repair these problems because they discovered electrical problems too. But they stated that the electrical problems are not the cause of the stalling failure. Recently my car glided into a curb because of these problems. Please explain why the d
Experienced mechanics share their insights in answering this question :
The stalling may well be caused by a failure of the crankshaft position sensor. This device provides timing instructions for the ignition system. When it fails, the engine no longer gets spark at the spark plugs and stalls. When the car stalls out, the brakes and steering cutting off are typical symptoms that go along with the car shutting off. To have all of this scoped out, a certified professional from YourMechanic can inspect your car for a correct diagnosis of the stalling issue.

If the engine quits while you`re under way, the car will lose power steering and soon power brakes. But you can still guide and stop the car, even if it takes longer and requires much more effort.
Engine stalling
Again, this is due to the computer not being able to meet the changing demands of the power steering system, causing the engine idle to drop too low. The engine`s computer will not recognize the demand for power, so it cannot compensate, causing the engine to stall.
What does it mean when a car stalls when braking? If your car stalls when braking, then it usually means you have a vacuum hose blockage in the brake booster or a leaking master cylinder. Or you could have a leak in the ABS system. In either case, this can be difficult to track down without professional help.
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition. Running out of fuel is one of the most common causes of engine stalling, but dirty fuel injectors or a plugged fuel filter can also be the culprit. Your engine needs air to run properly as well.
You will most likely experience a loss of power steering, making it hard to steer the car. Next you could lose your power brakes, increasing your vehicle`s stopping distance. Here are some tips on what to do if your car stalls while driving, so you can manage the situation and navigate your way to safety.
It is commonly applied to the phenomenon whereby an engine abruptly ceases operating and stops turning. It might be due to not getting enough air, energy, fuel, or electric spark, fuel starvation, a mechanical failure, or in response to a sudden increase in engine load.
Your fuel pump doesn`t stop pushing gas through to the engine once you`ve started your vehicle; it also pumps gas to meet your vehicle`s speed. If the pump cannot produce a constant stream of gas at higher speeds, your vehicle`s engine will sputter and threaten to stall.
Too much back pressure may cause the pump to stall if the fluid pressure overcomes the air pressure. To control flow, pressure and performance of an AODD pump it is important to have an air regulator installed to control the incoming air pressure.
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.
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.
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.
Stalling the engine in a manual car is NOT bad for the vehicle, so long as it`s not done 8 or 10 times every day.
Automatic transmission vehicles need to manage their level and pressure of transmission fluid when the car is idling. They do this with a component called a torque converter. When this converter fails, your engine will stall.
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.
The most likely issue is that a component is clogged. A clogged fuel filter is the most common reason, although a loss of power in your car could also indicate problems with the fuel pump or fuel line. Impurities or debris may be blocking the system, which causes the loss of power in a car.
Power Steering Switch (PSS)
Failure to correctly determine when the hydraulic pressure increases or decreases during a steering or non-steering manoeuvre may create an increased RPM condition at Idle due to overcompensation or intermittent engine stalling due to under compensation for the increased engine load.
The most common causes of poor hydraulic performance are particulate contamination, water contamination, clogged filters, high fluid temperature and incorrect hydraulic fluids.
Pump trouble is usually characterized by increased noise, increased heat, erratic operation of cylinders, difficulty or inability to develop full output, decreased speed of cylinders or hydraulic motors, or failure of the system to work at all.
Another symptom commonly associated with a problematic crankshaft position sensor is intermittent stalling. If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall.
A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.
Bad solenoid may be causing vehicle to stall.
The classic symptom of a failing master cylinder is a brake pedal that “dives” or sinks slowly to the floor while pedal pressure is being applied. Another sign to look out for is any leaks around the master cylinder. If a seal is worn out, it may leak past the seal and onto the pushrod that attaches to the brake pedal.
The O2 sensor will not cause the no start. The no start can be caused by the fuel pump or the ignition system. You should check the engine for spark and fuel pressure, when it is not turning on to help narrow the problem down.
A Bad Crankshaft Position Sensor
The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

Steering wheel shakes, light came on power steering assist failure 2010 Ford Escape
ANSWER : Hi there – this behavior, sometimes called "phantom steering shake" is often due to a steering torque sensor in the steering column. This device sense how much effort is being put into the steering wheel to make a turn. This determines how much "power assist" the electronic steering adds to your own effort to turn the steering wheel. If you are getting the "shake" while idling and still, this can be the beginnings of failure of this sensor. I would first go back to Ford to discuss the Recall (#14V284000), because this appears to be precisely the problem you are having. Escalate to Ford Customer Service. If this is unsuccessful, I recommend a steering wheel shakes inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, and give you an accurate assessment of damage and cost estimate for repairs.

Reduce engine power / check engine light is on
ANSWER : Hi there. Most of the time, reduced engine power is caused by a restriction of fuel, or the throttle body’s inability to efficiently mix air and fuel. This could be caused by a failing mass air flow sensor, EGR valve or other fuel system components. Since the check engine light is on, you should have a professional mechanic complete an inspection at your location to determine what codes are stored and which components require repair. This should resolve your issue.

Why no brakes
ANSWER : I would first recommend checking the brake fluid level. There needs to be ample brake fluid in the system to so that there is not a lack of hydraulic pressure. Secondly, check to be sure you do not have vacuum leak in the brake booster. As you may know, the brake booster operates off of vacuum pressure and when there is a vacuum leak, this can cause a loss of braking power from little to nothing at all. I would recommend having an expert from YourMechanic come to your home to diagnose your braking system and possibly repair the vacuum break booster.

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.
