Dash lights flashing on while driving

2013 Grand Jeep Cherokee Laredo, This car was recently purchased. Within ten days of purchasing it the issues began. The first time I was traveling on a highway still accelerating at around 52 mph, all the dash lights flashed on (everything the lights that flash on when first starting the car) and the car dinged at me like it does when I start it or do not have my seatbelt on. It happened quickly twice in succession. Three to four days later driving at night the dash lights and headlights flashed off for a second, very scary, I was on a back country road!! No sounds happened that time a

Hello, thank you for writing in. Electrical issues can be incredibly difficult to diagnose. Typically when every dash light turns on, there is an issue with the main power supply. This means an issue with the battery, alternator, wiring, or main fuse box. This would also explain why all power cut out to the vehicle. Focus on the charging system by testing the alternator and battery. Keep in mind the issue may need to be occurring for the problem to be found.

The Engine Check/Malfunction Indicator Warning Light (MIL) is yellow and looks like an engine. It monitors control systems for the engine as well as the automatic transmission. This is another one that will need immediate attention. The MIL may also let you know when the gas cap is loose or missing.
If the check engine light in your Jeep starts flashing, that means that the problem needs attention quickly and your Jeep should be brought in quickly. This blinking light usually indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system.
Most likely, flickering dash lights are due to problems with the alternator. In addition to recharging the battery, the alternator is in control of running the electrical components in your vehicle. If the alternator is failing, it may not be able to steadily supply enough current to all the components.
Yellow Warning Lights

Engine Malfunction: A yellow light that appears as an engine means your Cherokee`s engine is experiencing an issue. This can range from a loose gas cap to impending engine failure, so make sure to get service if you notice this light.

The check engine light — more formally known as the malfunction indicator lamp (MIL) — is a signal from the car`s engine computer that something is wrong. The light could be a minor issue, such as a faulty gas cap, or it could mean something more serious, such as a misfiring engine.
A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it`s in good condition. If you have a tank of bad gas in the car, your check engine light may come on.
A failed O2 sensor is the most common cause of a flashing check engine light. The O2 sensor is a critical part of the exhaust system, monitoring how much unburned oxygen is exiting the engine in the exhaust. The sensor sends messages back to the engine to adjust the mix of oxygen and fuel being used.
The first thing you can try, to turn off the car, then restart the engine. The second step is to disconnect your battery, wait for a few minutes then reconnect the battery. Another option is to continue to drive your car, and hope the light will reset itself.
If the battery isn`t working properly, it could cause the dash lights to flicker. It`s best to have your battery tested at your neighborhood Firestone Complete Auto Care, and install a new battery if necessary. Additionally, flickering dash lights can signify that there is something wrong with the alternator.
Next to the Grand Cherokee emblem on the exterior is an American flag, and on each end of the dashboard is a script that says, “Since 1941.” On the passenger side of the windshield is a seven-slot grille and headlights, and on the driver`s side of the third-row seat, there`s a Willys Jeep climbing the glass.
If you see orange or yellow dashboard lights it is reminding you that something needs to be serviced soon, like an oil change, or that something is wrong with your emissions system. While not an emergency, you should have a car mechanic look at the problem as soon as possible.
Coolant fluid absorbs the heat from your engine and disperses it through the radiator to prevent your engine from overheating. This yellow car warning light will come on when coolant levels are running low, to remind you to top them up.
Check your gas cap first. Many vehicles have a loose gas cap indicator that will be triggered before your check engine light comes on. If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light.
Just be sure to have your car inspected as soon as possible after the light turns on. Don`t neglect needed engine repair! If nothing seems out of the ordinary, you can continue driving the car. The cause could be anything from a faulty oxygen sensor to a bad MAF sensor.

If you see a red light appear on your dash, it usually indicates something very serious with the vehicle that you need to address immediately. These red warning lights include: Airbag Warning: This light appears as a driver in profile with a filled circle before them.

The rule of thumb is that if the check engine light is flashing, you can`t keep driving the car. It`s an emergency. Often it indicates an engine misfire. If you keep driving, you will likely cause irreversible damage, mostly to the (expensive) catalytic converter.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

ABS lights flashing on dash, temperature gauge increased. Multiple lights flashing on the dash. I put my seat belt on and they went away
ANSWER : Hello, this could be a number of things depending on how the vehicle is running now. If you possibly ran through a puddle of water or your belt is worn, it could have slipped and caused the lights to flash because the alternator and water pump were not operating.

Usually when the lights on the dashboard all light up together, you are losing voltage to the electrical system which on your vehicle would usually be the alternator. Now, if the engine temperature went up as well it sounds like you have multiple issues. It is also very common on your vehicle for the abs module to fail. If you need to have this checked by an expert, have a certified technician, like one from YourMechanic, inspect the ABS Light and other symptoms in person, so that this repair can be taken care of.

idle is low and engine light flashes when I drive.
ANSWER : Hello, and thank you for writing in. The vehicle may be having many types of problems. With a lack of power and a ticking sound, we must look at the level of the oil and the drive belt. Both can cause similar symptoms and noises. If your oil is low, then you have a leak and you need to turn your attention to finding it. If the belt is broken, frayed, loose, or a pulley is bad, then you will need to replace the belt and take any further corrective action. If these components check out, then you should turn your attention to the charging system and make sure the battery and alternator are working correctly. If necessary you can then resort to testing for proper fuel pressure, spark power, and look into the air intake system. For more diagnostic help, contact our service department to schedule an appointment.

First, the fuse 19 keeps blowing. When I hit the brake pedal my dash lights up. The third brake light acts like a running light.
ANSWER : Hi there. Check the wiring on the vehicle to the tail and brake lights. There is a cross short that is causing the lights to blow the fuses and make the tail lights brighter than normal. If you need further assistance with your electrical issues, then seek out a professional, such as one from Your Mechanic, to help you.

signals, daytime running lights are not working, park brake light on dash is on steady and chime is dinging steady 4×4 wont engage
ANSWER : This is likely a brake light switch problem. I would suggest testing the brake light switch which should be located down by the brake pedal. This may also be a computer problem as well as indicated by the other lights on in the dash. I would recommend having an expert from YourMechanic come to your home to possibly replace the brake light switch and diagnose with a scanning tool which will download useful data from the truck’s computer indicating what specifically the problem may be.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit.

Security light constantly on or flashing, battery light flashes, radio locked, power locks and dome lights don’t work. Please help
ANSWER : Hi there, thanks for writing in. I’d be happy to provide my insight.

I would not replace the BCM without a thorough diagnosis first. GM vehicles such as yours suffer from two small wires that break in the steering column. They attach to the ignition lock cylinder that is part of the security system. But this doesn’t cause all the other power problems and the car will crank every time. If the security system is acting up, you can turn the ignition in the run position for ten minutes. If the car starts after ten minutes, then you most likely have a security issue.

The first thing I would do is to connect a scanner and see if I could communicate with all the computer modules. This will be a good indicator of whether or not the BCM is failing. In addition, any codes that are stored could be retrieved and these are very often excellent guides as to what is the problem.

If I were working on your car, I would look at all the connections that supply power to the fuses. This will require a repair manual or access to a professional level automotive information system. Following this, I would study a wiring diagram to see if there is a common connection that supplies power to all of the systems that are not working.

When it comes to computer modules, they are rare to fail. For this reason, I rule out every other possibility first before I suspect and then begin to directly test the suspected module. I recommend the following inspection to help you diagnose your car: Electrical problems are not working inspection.

Hope this helps, and best of luck.

Good luck!
