I just got a tune up but car is leaking coolant and keep shutting off

My car has 191445 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
I’m assuming your wondering if the tune-up has contributed to your car shutting off. It is possible. I would take it back to the mechanic and let him know. But let’s be clear that this may be merely coincidental. So please give the mechanic the benefit of the doubt. This will set him or her at ease and they will be able to do better work for you. Of course, customer service is the front line of auto repair, so if you are not satisfied with it, it is your right to find someone you trust. I recommend having a car is stalling inspection completed by a professional technician.

Your coolant leak can be addressed at the same time. It is important to note, your car has high miles and this is most likely the reason for any problems that have occurred. The timing can be suspect of course, but I explain this by asking why it is a light bulb fails? They just do when it is its time. The same goes for every component on your car.

The important thing is how you approach the mechanic. Hopefully he or she will instill trust and you will get to the bottom of these failures.

Good luck!

How to Identify and Fix Common car Problems ?

Common reasons for this to happen:

Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine.

Here are few reasons your Jeep might die while driving: Faulty fuel injectors. Bad fuel pump. Faulty or dirty sensors that can disrupt the fuel and air mixture.
The most common reasons a Jeep Cherokee won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
The most common reasons a Jeep Grand Cherokee won`t start are a dead battery, an alternator problem, or failed starter.
Cars shouldn`t shut off while driving, but when they do, the most common culprits are: A bad crankshaft position sensor. Other sensor issues in the engine. A faulty fuel system.
If the vehicle randomly shuts off while driving or stationary, there is usually an issue with the engine. Typical patterns here are issues with the ignition system, mixture preparation or fuel. A known error here is that the vehicle was refueled with the wrong type of fuel.
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition.
The most common reasons a Jeep Cherokee 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.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
The most common causes for a Jeep failing to start despite its radio and lights working are issues relating to its battery or other cranking/start-up components, such as the ignition switch, starter, or spark plug. These pieces might be damaged, dirty, or corroded.
Though some Cherokees have driven over 300,000 miles, most drivers should expect to see very serious problems begin to pile up at about 175,000 miles.
Use a multimeter to test the health of your Cherokee`s battery. Ideally, your battery will have a charge of 12.6 volts if it is fully charged. If a multimeter shows your battery has a charge of 12.4 volts or lower, it may not have enough power to crank your Cherokee`s engine.
Many modern vehicles are designed with several fail-safes to help protect the engine in adverse conditions. One of this is an automatic shutoff when the oil pressure drops to a certain level, or the oil level drops too low (note that this is not true for all cars). This causes the engine to stall and die.
A failing fuel pump is one of the faults that can cause this. Other likely problems would be the battery, alternator, battery cable, wiring harness fault, crank or camshaft position sensor. The fuel pump may have been replaced because it was not turning on.
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.
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.
An engine that shuts off and then restarts right away can be cause by quite a few things. A fuel pump on its last leg, a bad crank sensor, and ignition issue. It`s almost impossible to pinpoint without a hands on inspection but a good place to start would be scanning the computer for codes.
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.
In the Jeep Problem, the goal is to maximize the distance the jeep can penetrate into the desert using a given quantity of fuel. The jeep must not take all the fuel from the base at once. The jeep is allowed to go forward, unload some fuel, and then return to its base using the fuel remaining in its tank.
Transmission issues, steering problems, and issues that can lead to engine stalling are commonly-reported issues for Jeep drivers.
If the fuel pump relay fails the fuel pump will be left without power. The engine may still crank when the key is turned, however it will not be able to start due to lack of fuel. This symptom can also be caused by a wide variety of other issues, so having the vehicle properly diagnosed is highly recommended.
Cherokees from 2014 and 2015 are the vehicle`s worst years. These have many recalls and complaints, most regarding critical powertrain components. The best years for the Jeep Cherokee include those from 2018 and 2020. These have fewer problems and have the highest owner ratings.
If well-maintained, most Jeeps can exceed 200,000 miles, and some people have even been able to maintain their Jeeps for up to 20 years.
If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won`t turn over – no matter how many times you turn the key. A faulty relay often produces an audible clicking sound when you turn your car.

My car shuts off while driving and then turns back on multiple times or shuts off after driving and car turns off.
ANSWER : Hi there. Check the alternator and make sure that the wiring it connected tight. Check the battery cables and make sure that they are tight and clean. Look for any loose ground wires to the chassis on the vehicle. If everything checks out to be working correctly, then the PCM may need to be replaced as it may have a battery disconnect condition. If you need further assistance with multiple functions shutting off, then seek out a professional, such as one from Your Mechanic, to help you.

My car shut off while at a stoplight. I got it started only for it to shut off agin. It starts then shuts off.
ANSWER : Hello, thank you for writing in. The vehicle is stalling due to an electrical issue (typically pertaining to power supply or a sensor), a lack of fuel, or a failure with the ignition (spark) system. You will want to start by scanning the vehicle for diagnostic troubleshooting codes. Use any information found there to help guide you to the system or component that is failing. Without that information, you will want to test the fuel pump, ignition cables, spark plugs, and alternator function. Further testing may need to be done based on those results. For more help with diagnostics, contact our service department to schedule an appointment.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Car starts but keeps shutting off when I apply brakes or slow down
ANSWER : Hi, thanks for writing in. Having the precise codes is very important– even if the Check Engine is no longer illuminated. There can be transient codes that have not yet set off the light. The idle air control valve and throttle body may need cleaning. With your mileage clogged fuel filter and dirty/leaking injectors are something to check as well. A clogged catalytic converter is a possibility– that would be most apparent by an inability to build up speed, or take on hills where more power is required. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

Car shuts off, won’t stay running
ANSWER : The most common problem on this vehicle is the fuel pump and fuel pump module. If you remove the rear seat that the fuel pump cover is, on the passenger side. Listen to the fuel pump when it is running and when the car stalls your fuel pump will stop running about three to five seconds before the engine dies. Then you’ll know if the fuel pump is the culprit or not.

You can try and replace the fuel pump module first then replace the fuel pump. However, the fuel pump can short the module out, causing both to be bad and would need to be replaced. If you need assistance with this, feel free to contact a certified mechanic who can diagnose your starting issue firsthand and help you fix it accordingly.
