In the article, you will learn about many of the problems that may arise with your 2015 Jeep Grand Cherokee. These include things such as transmission being sluggish, automatic headlights not working, and the engine control module.
The majority of these problems are common among most cars out there on the market today. However, this does not mean that they should be ignored or dismissed altogether because if left untreated for too long they can lead to more serious issues down the line. Keep reading to find out what you need to know about these Jeep Grand Cherokee issues so that you can make an educated decision on how to proceed in dealing with them.
Transmission being sluggish
This is one of the most common problems that you can come across with your Jeep Grand Cherokee. It typically manifests itself in the form of a transmission that will not shift properly or a transmission that will vibrate while it’s engaged. It might also become difficult to engage the car even when it is in drive mode. The cause for this problem can be traced back to a few different things. These include engine starting issues, a defective clutch, and it could also be caused by an issue that is located near the transmission dipstick tube. In most cases, this is a problem that points to the transmission as being the source of the issue. The good news is that it’s an easy problem to resolve so long as you have a reputable mechanic working on your car for you.
Automatic headlights not working
Another common problem with 2015 Jeep Grand Cherokee models is their automatic headlights not working properly. This happens when a switch for the auto-headlights malfunctions and fails to turn them off or on while they are supposed to be engaged. While there are no certain ways in which this can be resolved, there are some theories out there that might help you along in finding an answer to this particular issue. One potential solution includes replacing the headlight switch but then again, that’s not an actual guarantee that the problem will be resolved. If it does not, then you might have to take your car to a Jeep dealership so they can examine the issue for you and figure out what is causing it.
Failing 2015 Jeep Grand Cherokee Engine control module
One other common problem that you can come across with your 2015 jeep grand Cherokee is its engine control module failing completely. This happens when the ECM fails because of a short-circuit or if it freezes up entirely. When this happens, it may end up starting itself randomly or turn off while the car is being driven which could lead to accidents at high speeds. To make matters worse, if this occurs during winter storms, even more damage could potentially occur as a result. Taking your vehicle to a Chrysler dealership would be the best course of action in this case.
Poor fuel economy
The average consumer can expect anywhere from 15-22 MPG for their 2015 Jeep Grand Cherokee models when they are in optimal conditions and not exceeding speed limits. However, if you happen to find yourself with poor fuel efficiency or even worse no fuel efficiency this could mean that there is an issue with your engine which should be addressed promptly by a mechanic. If left untreated, it could lead to serious problems like not being able to start the car at all because of a bad ECM and stalling while driving among other things. These issues can easily be resolved through regular wear and tear but in some cases they may point to more serious problems as well which you should address immediately.
Engine performance issues
This is something else that you might notice if your Jeep Grand Cherokee starts to show some signs of poor engine performance. This could be caused by a bad catalytic converter which is responsible for the exhaust fumes coming through when it’s in use or when the car is started up. Another common reason for this issue can be traced back to an air leak inside the car which would cause it to perform under its optimal capacity. If left unresolved, this could cause serious damage down the line in addition to causing significant repair issues for yourself and anyone who is with you at that time. If either of these are true then it will need immediate addressing even though there are no guarantees that the issue will be resolved easily.
Rear windshield wiper
Another issue that has been reported as occurring with 2015 Jeep Grand Cherokee models is that the rear windshield wipers may stop working for no real reason or it can even cause them to work improperly as well. This particular problem tends to point to a failure inside of the power supply system which leads us back to one specific area: the circuit board inside of your car’s console. Thankfully, this is an easy fix and you should only need a pair of jumper cables and a flathead screwdriver if you don’t want to waste too much money on it just yet. It would be best advised that you try this method before taking your car in because it could save you plenty of money in the long run.
Malfunctioning rear window wiper
Similar to the issue above, if your 2015 Jeep Grand Cherokee’s rear windshield wiper stops working all of a sudden there is likely an underlying issue with its circuit board which has failed and needs to be replaced entirely for this particular problem to stop happening. On top of that, you may have spilled liquid on it at some point while driving which would have caused the short-circuit required for it to fail completely or even malfunction while being used. You should consider trying this method to see if it resolves the problem before taking your car into a mechanic for servicing just because you never know when you might come across one choice being cheaper than another.
Difficulty in starting the car
Another issue that can happen with your 2015 Jeep Grand Cherokee is that it may become difficult to start even after you have drained off all of the fluids and let it sit for an extended period of time vertically. This could be because there is too much pressure being exerted on the starter which causes it not to create enough power to start up your vehicle properly. It could also be due to a problem inside of the ignition system itself which will require significant troubleshooting before being addressed so you should try using jumper cables if this occurs when you are trying to turn on your car one day. If this doesn’t work then you might need new spark plugs at the very least or something more serious like a bad solenoid pack (which contains the spark plugs and ignition coils inside of it).
2015 Grand Cherokee Transmission issues
Something else that can happen with your 2015 Jeep Grand Cherokee is if the transmission starts to fail after a certain amount of time has passed while you are driving around. This can cause your vehicle not to move at all or even make strange noises like grinding gears while trying to drive along which would definitely make its way onto this list since it’s such an important part of any motor vehicle that needs to be taken care of if you want it running properly for a long period of time. The one good thing about this issue happening is that it’s usually due to very little effort being put into taking care of things in terms of oil changes and other necessary maintenance procedures before the transmission itself winds up failing on your car.
Issues with the low beams
Another problem that can occur with your 2015 Jeep Grand Cherokee will be if the issue you are having is that of one or both of its low beam headlights not working at all whenever you attempt to turn them on. This could be because one of the headlights have burned out so you should try replacing both bulbs to see whether this fixes it, especially if their filaments are showing signs of excessive burning which could result in a short circuit occurring within the wiring leading up to it due to being frayed at some point along its path through your car’s engine bay.
Problems with A/C evaporator
Having issues where the air conditioning system begins to work inconsistently in your car could be the result of something being broken with its evaporator which keeps it free of any ice or frost so that you can have cold air blowing out when you use the controls on your dashboard to change between different fan speeds. This is done with a small heating element inside of it working together with what’s known as an expansion valve that is similar to how valves are used within plumbing systems. However, they are not too complex devices since they typically consist of little more than a series of rubber hoses, copper tubing coils, and wire routing around these connections which allows for them to maintain their shape while under pressure from both sides. You would want to make sure there isn’t any overfilling occurring over.
Conclusion
Here is a list of the many problems that may arise with your 2015 Jeep Grand Cherokee: transmission being sluggish, automatic headlights not working, and engine control module among others. These issues can easily be fixed by taking care of simple maintenance procedures before they occur or even more serious repairs if you find yourself in this situation where you need to take it into service for some reason. The next time you’re looking for a car to purchase, consider one from the Jeep line-up which are known for their durability and quality engineering!
