How long can it take an ECU computer to go bad?

I purchased a car from a used car dealership and after a month and a half the car became inoperable with oil leaks, needed 6 new spark plugs, six new engine coils and a brand new ECU computer. Is there anyway that this could have been all caused in a month and a half?

My car has 110000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello, and thank you for writing in. The vehicle likely did not suddenly develop all of these problems. Oil leaks in particular happen due to excessive engine wear. The spark plugs and their coils tend to be regular maintenance with the age and mileage of the vehicle. The engine control unit is a component that can last the lifetime of the vehicle, or develop issues after 100,000 miles. What causes them to fail is a bigger question. It typically comes from bad manufacturing, or some kind of electrical work done to the engine. With the issues you have been having, make sure that your cooling system is working correctly and has clean coolant. For more help with a general tune up or inspection of the vehicle, contact our service department to schedule an appointment.

Your engine could cut while you`re driving, as well, if the ECU malfunctions. Once you`ve coasted to a stop, you won`t be able to get your automobile started again. It`s a good idea to get your engine control module tested at the first sign of trouble.
The spark plugs and their coils tend to be regular maintenance with the age and mileage of the vehicle. The engine control unit is a component that can last the lifetime of the vehicle, or develop issues after 100,000 miles.
The main symptoms of a faulty ECU

Well-known examples are: engine failure light (MIL light) that lights up on the instrument cluster, car that goes into emergency mode, the car shakes or when the engine no longer runs on all cylinders. It can all indicate a malfunction of the engine control unit.

The ECM will usually last the lifetime of the car, though it can go bad. In fact, the computer can fail as early as 75,000 miles, and around 125,000 miles is the most common range for ECM replacement.
A damaged ECU can cause problems when shifting gears in an automatic transmission, or cause sudden jerking or stopping that`s similar to transmission problems.
One thing that will damage the ECU is if there is too much voltage going into the computer unit. For that reason, you should not do anything that will result in high voltage occurring, such as using cheap cables to jump start your vehicle – these usually result in strong and erratic voltage.
In the majority of cases, the faulty ECU can be repaired or reprogrammed, and this type of repair will usually run between £150 to £750, depending on the make and model of your vehicle.
You can use a bench test setup, which simulates the car`s electrical system and sensors, to connect your ECU and check its operation. You can also use a software tool, such as an ECU simulator or a diagnostic scanner, to communicate with your ECU and monitor its parameters, codes, and outputs.
The ECU affects almost every aspect of your engine`s performance – from torque to fuel efficiency – so modifying it can be an excellent way to increase your car`s performance.
A problem with your ECU could spell trouble for your engine, Issues with timing, fuel-air mixture, and overheating can damage vital engine components over time, which can be expensive to repair.
The ECU Installation is simple & takes about 15 minutes to complete. These instructions are meant to be a generic guide to try fit most cars. Before reconnecting the ECU make sure that: Battery is charged over 12v.
Although the ECM power relay is meant to last the entire lifetime of your vehicle, sometimes it can still fail. If it does, it`s usually due to moisture issues or a power distribution issue. You won`t be able to leave the part as is since your vehicle needs the ECM power relay in order to run.
Can a Bad Car Battery Cause Computer Problems? A faulty battery can have an impact on all of your automobile`s electronic components, including the car computer. If a malfunctioning battery is unable to provide the necessary electrical energy to a computer, it could result in issues.
Battery drain or dead battery

A failed ECM power relay can also cause a battery drain or dead battery. If the relay shorts it can leave power on to the computer, even when the vehicle is turned off.

Can a car run without ECU? No, Modern cars have to have the ECU as it controls everything the engine does hence Engine Control Module.
Repairing an ECU can be tricky. For starters, this is not something that you or your neighbor can probably do successfully. It`s not like changing your oil or changing a tire. The engine control unit is a computer and a highly advanced piece of technology.

My car won’t go past 35mph
ANSWER : Hi there. From the description you provided, your vehicle has problems with the transmission again. You stated it will not shift into 3rd gear again, like before the transmission was rebuilt. If the transmission is again the problem, it should be covered under warranty. It could be a faulty shift solenoid. The shift indicator not reading properly could be a faulty transmission position sensor. If this is an overall lack of performance issue, according to your last statement, then possibly you have a restriction in the exhaust system. I recommend having your vehicle’s problems inspected and diagnosed by a certified technician from YourMechanic.

I bought a used car 2010 nissan versa and when I go uphill it slows down alot. When going uphill it says go 60mph I am at that sp
ANSWER : Hi there. When a car is slow to accelerate it can be caused by multiple issues, ranging from fuel systems that are clogged or damaged to an ignition system component failure. It is also possible that something in the driveline system is dragging which causes the lack of acceleration. Since there are so many different possible issues, the best way to start the diagnosis process is to have a professional mobile mechanic from our team come to your location and complete a car is slow to accelerate inspection.

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.

Shifting from 2nd to 3rd, car stopped going fast. Now it won’t go at all.
ANSWER : It is possible that your clutch has failed. The sound you are hearing is likely due to the clutch not engaging with the engine due to it being worn. I would recommened having your transmission inspected by a qualified transmission expert to determine if your clutch requires replacement in order to resolve this issue. This inspection may require removal and partial disassembly of the transmission in order to verify that the clutch has failed.

I have a bad oxygen sensor, bad power steering sensor, and a bad cam shaft sensor? Should I replace any of them?
ANSWER : When you say you have three bad sensors I can only assume you have had them tested and the end result is three bad sensors. If they tested bad then they should be replaced. The power steering sensor senses the load of the steering on the engine so it can raise the idle during parking maneuvers. The O2 sensor is used for fuel control and it may effect engine power and fuel mileage. The camshaft sensor cay cause no starts, engine running problems and all three will turn on the check engine light.

When you take a valve core out, about how long does it take until the tire is flat?
ANSWER : The air will leak out in less than 30 seconds depending on how big a tire is and the volume and pressure the tire holds. A larger truck tire will take longer than a small low profile tire due to the volume of it they hold.
