Image Credit: JeepA mechanic has taken to TikTok to voice his displeasure at how a popular Jeep SUV has seemingly been designed to make one of the most important parts incredibly difficult to repair or replace. Mechanic Old Snap (@oldsnap85) discussed it in a TikTok video that has started to gain traction.In the video, the mechanic is working on a 2020 Jeep Grand Cherokee, which he used to make his point. He claimed that the auxiliary battery on the SUV, one of the most important parts of any car, is in a nightmare spot to replace.There is a slight degree of sarcasm in the mechanic's voice with all of this. "People like to act as if automotive engineers do not have the consumers' best interests in mind while designing vehicles. I'm here to prove that wrong," he stated in the video.AdvertisementAdvertisementHe compared the auxiliary battery with the main one under the hood and how easy it is to jump-start it if it is dead, or to replace it if you need a new one entirely. His video does make you wonder if automotive manufacturers do think about consumers when it comes to replacing parts.What Beef Did the Mechanic Have With the Jeep Grand Cherokee?In the video, the mechanic pointed out how to get access to the battery under the hood of the Jeep SUV. A twenty-twenty Jeep Grand Cherokee has a dead battery. All you gotta do is pop the hood, get a charger, a jump box, a set of cables—it doesn't matter. They give you so many options," he said. That certainly sounds easy enough, with little hassle involved.The sarcasm, however, ramps up a notch when we get to the auxiliary battery location. "Come back here to the passenger door. Pop that open. Slide your seat all the way forward, all the way up. You come back here," he said. "Come back here. You just have this little plastic tray. Four clips, pops right out. Get to your auxiliary battery. Thirteen-millimeter nut, 13mm nut. Boom, terminals are off. Tie down, 10mm. Boom, that's off. Slide your battery right out. Underneath is a tray. Thirteen, 13," he added."Boom, that pops right out. That's your tie-down for the main battery, too," the mechanic continued. "Then you just got a 10mm. Ten millimeters, two drains. Then your battery just slides right up and out. I don't think they could design it any easier. They definitely have your best interests in mind," he said. That process does sound like a hassle, and quite convoluted if you want to replace it at home. But why is the auxiliary battery located under a passenger seat?There Is Some Logic to the Battery LocationImage Credit: JeepWeight distribution and space efficiency can be reasons for this change of battery location. Placing it inside the car frees up space for components such as turbochargers, emissions control systems, or other accessories related to the engine under the hood. Manufacturers can also shift the weight towards the center of the car, allowing for better weight distribution and balance for whichever car it is.AdvertisementAdvertisementClearly, getting to the batteries inside a car is a bit of a pain. In fact, with a lack of ventilation in that area, the batteries could get a bit hot, compared to under the hood, where air is allowed in for cooling. If a battery runs hot all the time with little to no cooling, it could shorten its lifespan. Conversely, moving batteries away from the hood area reduces the risk of battery fires in a head-on collision. But it is clear that, to get to a battery, the best place to put it is under the hood of a car.If you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
