The transmission started not shifting as I was driving down the road and the relay fuse box caught on fire and I think it’s where the back seat lays on top of the fuse box which rubs the fuses. Which is dangerous bc it catches on fire and could blow the car up while driving

Vehicle refused to start. No warning light illuminated on dash. Checked Fuel Pump Relay and it was burned. Replaced and it keeps burning and getting extremely hot. Relay has been replaced x4. Fuse Box is starting to melt. Wiring to Fuel Pump is free of any corrosion on wiring/prongs. Interior starts to smell of heavy smoke increasing the risk of a FIRE in the rear seats.

Bought my car Sept. 2022.Within the first couple of months I started having intermittent problems that seemed fuel related.After some research I found out my car had a TSB that has been out since 2016. With this knowledge I took the back seat out of my car and the problems all stopped.June of 2023 started having some problems that were sort of similar to what I was experiencing before with some power loss, had vehicle taken to mechanic who diagnosed an interlock system problem.I thought maybe that would fix all my problems and put my back seat back. I travel 4 hours once a month to go see my son and only took my car once on that trip because of not being able to have a back seat.Me thinking the interlock fix was the solve all to my problems I put the back seat in and started my drive to go see my son. 3 hours in stop for gas, try to start my car, cranks won’t start, not getting fuel. Called mechanic who just worked on my car, suggested to check my fuel pump fuse and fuel relay, find my fuel relay is melted. Replace fuel relay and pulled the back seat out, car fires right up no problems. Continue hour drive to see my son, picked up my son so had to put the back seat in. Drive about 7 blocks and stop at Walmart, try to start car and same problems as before. Replace Fuel relay, propped up the back seat around the fuse box trying to still make it safe enough for my son to ride back there, no more problems that trip, propped seat left leaning in the back. August-Was driving down the Highway at 65mph with the cruise on, when all of a sudden my car begins to lose power and proceeds to stall with no warning. Lost complete control of steering and had minimal control breaking, had to coast to a stop with no breaks or steering, lucky was on a straight rural hwy, can’t imagine if I was in the city. Seat had fallen up against fuse box fried fuel relay again and the control module. Take to shop for repair, control module, fuel pump replaced NSB complete all at my expense.

I went to start the vehicle and it failed to start. I found the fuel pump relay to be badly burned ??. On the 30 pin. The board was melted at the 30 pin spot for the fuel pump relay. I purchased a new relay from NAPA. I questioned whether they had a new replacement fuel pump. They told me it was not available only through the dealership. My concern was that where the relay was located at there was a possibility of a fire given how badly the relay and board was burned. I replaced the relay and purchased an extra incase this might happen again. To my surprise it happen just days later while I was driving on the expressway. I had to get off the road immediately. Engine died, no power steering. I checked the relay, it was smoking hot. I will have to have the problem resolved. There is no way a relay should ever get hot, let alone that hot. The fuel pump fuse was not effected. Why is the relay not protected from getting so hot. There is definitely a real risk of fire. No one sits in the back seat normally. But, my grandson's. This should not ever happen.

The fuse box under the back seat has been having issues of burning for the fuel pump relay. It then in turn shorts out the fuse box which keeps needing to be replaced. This is a safety issue as it it catch fire under the back seat.

The fuse block is shorting out and melting and causing the fuel pump relay to burn.
