2012 jeep grand cherokee battery dead and can't start it to move the seat to get to the battery underneath also tried jump starting from the terminals under the hood but terminals started smoking and didn't start truck is there any other way or why it would be smoking and burning the terminals?
My car has 136000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
It is possible that the smoke could have been due to the jumper cables being installed backwards. I would recommend double checking to make sure that you connected the cables properly. If you did connect the cables properly and the vehicle is still smoking, it is likely that a major electrical short has occured within your vehicle. If this is the case, I would recommend having the vehicle towed to your local Jeep dealership as the issue may be covered under warranty.

If your 2012 Jeep Grand Cherokee battery warning light comes on while driving, be hopeful to turn off your accessories, so the battery doesn`t jettison added. The warning light usually means that the alternator isn`t working properly meaning you are operating solely on battery power.
The most common reasons a Jeep Grand 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.
Jeep commonly utilize a dual battery system for their cars, which entails one battery being the primary battery that cranks the truck and the other is the secondary battery that runs the vehicle`s accessories. This allows all Jeep functions to receive the necessary power to operate optimally.
Buying a Replacement Battery for Jeep Grand Cherokee
Your Grand Cherokee doesn`t have an expiration date, but its battery does. On average, auto batteries last anywhere from three to five years. Don`t get stranded by your Grand Cherokee`s car battery. Replace it regularly instead!
Slow engine cranking – When you attempt to start your Jeep, especially when it`s cold outside, it cranks over slowly. This is a classic sign of a failing battery. The battery “dies” easily – If your Jeep isn`t running and you leave your lights on, the battery should power the lights for 10-15 minutes.
A dashboard battery light basically means there`s a battery charging problem. Your car isn`t getting enough voltage from the car battery to operate properly. It needs more “juice!”
The first is to check the wiring from the battery to the starter. They should be looking at voltage drop across the starter circuit. They should also be looking at the starter and neutral safety switch. The second issue may be the key fob is weak.
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.
Engine failure is one of the most serious reasons your Jeep Cherokee may not be starting. That can be due to several things, such as a blown head gasket or a cracked engine block. Let a specialist at the auto dealership or a trustworthy mechanic check this issue out.
Vehicles with manual transmission are easy to jumpstart without cables. The only method to start an automatic car with a dead battery is to use a portable battery charger. If you drive an automatic car, make sure you have a simple portable charger in your roadside emergency toolkit.
“When a vehicle battery dies, the most common solution is to jump-start the battery using jumper cables and another vehicle. However, if proper steps are not taken, there is no guarantee this method won`t cause damage to the vehicle,” says David Bennett, AAA`s manager for repair systems.
While the GRAND Cherokee has 2 batteries (one for starting, one for ESS), the regular/plain Cherokee (Latitude, Limited, whatever) DOES NOT have 2 batteries. It has only one main battery under the hood.
While not all Jeeps utilize a dual battery system, it is becoming a more common feature in their vehicles. The Jeep Wrangler and Jeep Gladiator vehicles are well-known for their two-battery setup. You might be wondering about how two batteries can function together in a vehicle.

Hello hi, I have a 2009 Jeep Grand Cherokee 3.7 liter there is a problem with my truck that I can’t figure out when I get stuck in
ANSWER : Hello there. Sometimes when the engine gets hot under the hood, electrical and ignition components can become ’touchy’ and cause starting issues as you have described. In most cases, the issues are caused by faulty electrical connections between a wiring harness and a critical ignition system component like the crankshaft position sensor. The good news is that when this occurs, it typically creates an error code that is stored in the ECU of your Jeep’s computer that can be downloaded by a professional mobile mechanic when they complete a check engine light inspection. Once they are able to retrieve codes, they can begin the diagnosis process and hopefully determine what needs to be replaced to resolve your issues.
I have a 2000 jeep grand Cherokee limited 4.7L V8. I was gone for a month in a half tried starting my jeep up yesterday and nothin
ANSWER : It may be normal engine electrical drain on the battery if the vehicle sat for a month or more. Once the battery is recharged fully then you can see if it will idle again. Just jumping off and only running a few minutes may not charge the battery enough to let it idle on its own. You should use a battery charger to recharge battery and retest it to see if it still stalls. You may have a bad battery and need to relearn the idle. If it still stalls then the idle control valve may be stuck closed and need to be replaced.
Car will jump start fine. But when I try to start it from the new battery, it all goes black and power goes out completely
ANSWER : Hi there. It sounds like your new battery may be faulty. If the vehicle jump starts ok, then this is a sign that the new battery is not providing enough cranking amps to engage the starter. It may have a bad cell that is causing your symptoms. A bad cell prevents the battery from operating properly and can wreak havoc on electrical systems. The only repair is to replace the battery if this is the case. Have the battery tested with a digital battery tester that provides current voltage, cold cranking amps, and state of health. I suggest having a qualified technician perform an inspection to confirm this and avoid replacing any unnecessary parts. YourMechanic has several available technicians that can assist you with a no-start diagnostic so the correct repair will be done.
The battery is dead and wont jump
ANSWER : Hi there. More likely than not, the problem you are describing is not caused by a dead battery; but instead, bad battery cables. However, it is possible for a battery to drain to the point where attempting to jump start will not work. The best thing to do in order to correctly diagnose this problem is to have a professional mobile mechanic complete a car is hard to start inspection.
I put in a new starter and battery and my Jeep will not start. Please help me get my Jeep to start.
ANSWER : Hi there. Check to see if the wiring to the battery and the starter are tight and clean. A bad connection will cause a no start situation. If the battery cables and wires are all tight and clean, then go in the cab and turn on the ignition switch and see if any thing in the cab works.
If nothing comes on, then check the fuse box for any blown fuses. If all the fuse are good in the cab and under the hood, then the ignition switch needs replaced. If the ignition switch is good and the accessories come on, then either the starter relay in the fuse box has failed or the wires from the starter relay to the ignition switch has become burned or loose. Check the wires from the starter relay on the starter to the ignition switch. If everything checks out to be good, then the ignition switch needs replaced.
If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from YourMechanic, that can assist you with your no start situation and help you with the power surge.
I have Chrysler 300c. Battery light came on, changed battery and alternator but power still getting drained and battery light still comes on.
ANSWER : Hi, thanks for writing in. This may be a sign of a failing starter relay. The starter relay is a small unit near the starter that directs power to the starter from the battery. When this fails, it may cause a clicking sound and will not allow the starter to engage the flywheel when you turn the key. I would suggest having a professional from YourMechanic come to your home to diagnose your starting issue to determine the solution to get you back on the road.
Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.
