2016 Ford Mustang: fire, smoke or burning smell

Filed Sep 29, 2026 · Electrical · CA · fire

A new Walmart-brand EverStart Plus 96R, 590 CCA automotive battery was purchased on August 4, 2026, and installed in a 2016 Ford Mustang Convertible. On the evening of September 26, 2026, my family and I drove the Mustang and returned home at approximately 11:00 p.m. The vehicle operated normally. There were no warning signs, electrical problems, overheating, or other indications of a mechanical problem. The Mustang remained parked and untouched overnight. At approximately 2:00 p.m., 15 hours later, on September 27, my daughter came into the room and told me that the car was on fire. Riverside County Fire responded to the scene. Fire personnel specifically asked whether the Mustang had been driven or worked on that day. I told them it had not. The vehicle had remained parked since approximately 11:00 p.m. the prior evening. Fire personnel continued to suppress the fire, investigated the engine compartment, cut the battery cables, photographed the vehicle, and advised me that the battery appeared to be the possible source of ignition.

On or about June 24, 2026, the CHECK ENGINE light came on. Since I was near the local Ford Dealership, I stopped there. The car was evaluated the next day. I was told the the gas tank assembly and pipe had to be replaced. The repair was almost $4000. My car only as 63,117 miles on it. Before the problem was diagnosed, I was getting lousy gas mileage and assumed it was because the government was allowing more ethanol. In fact, the problem could have been disastrous... The car could have caught on fire . The car was in the repair shop until July 2, and I had to rent a car for $300. I am unable to download a photo I have of the gas tank which shows these numbers: E-11 34RI-020135 as well as AD46319. I have attached the bills from the CERTIFIED FORD repair shop. Please note that the 2015 Mustangs were recalled for gas tank replacements. I have a 2016.... Seems like my car may have had a faulty gas tank installed as well. The mechanic said he had replaced a couple. Nite that the car had just over 63000 miles

Nelson v. Ford Motor Company is a class action lawsuit targeting a defect in Ford's 2.3-liter EcoBoost engines. The suit highlights coolant leaks into engine cylinders, overheating, and catastrophic engine failures. I have had my 2016 ford mustang ecoboost in and out of mechanic shops for months now accumulating well over $7K in out of pocket expenses. I have been to multiple mechanics trying to diagnose and fix the problem but in the end it was a design flaw in the 2016 ford mustang ecoboost 4 cylinder which caused it to leak coolant, misfire, and overheat. I have been having this problem for some time now, this put my safety and the safety of others at risk because I had to slow down dramatically in order to pull over on the freeway due to the engine overheating from coolant loss. I've also experienced problems like trouble starting, rough idling, loss of coolant, and huge clouds of white smoke coming from the exhaust upon start. I have saved every single receipt and invoice breakdown since this problem began. My mechanic has also been documenting everything including taking notes and photographs of every issue. My car is currently in the shop right now being worked on. My mechanic says that he can temporarily patch the problem with a high performance head stud, copper sealant, and an ExtremeHeat metallic repair paste by JB Weld to momentarily solve the issue. He says that he does not know how long this patch will last so he is insisting I either get a new car or to see what my options are regarding the class action lawsuit filed against Ford.

Smoke came up from under both seats within a few weeks of each other, found burned harness and plug at both heated/ cooled seat control modules mounted under seats. Researched and found a fix that will cost hundreds of $$ per seat but no recalls. I would think smoke and burning electrical in the interior of nearly ALL Ford products with heated/ cooled seats would be a safety recall?

The bolts holding on the valve covers were not torqued correctly and were finger loose when I found them. I was lead to this discovery because there was a constant burning smell which turned out to be oil leaking out and falling on the exhaust. I found out on a forum that this seems to be a very common problem with 15-17 Mustangs. Additionally, there is a Technical Service Bulletin out explaining to mechanics that Ford did not add enough bolts to hold the valve covers on, leaving 4 or 5 blanks on both sides. Also, the newer 5.0 engines have all the necessary bolts, so basically, Ford thought they could save money by skipping 8-10 bolts on each car. I've already spoken to a Ford dealership and they said they'll have to charge me (unsure of how much yet) to repair a car they didn't build right in the first place! Please look into this.

This specific car model is a 2016 Shelby GT350 tech package that I owned for at least 7 months. In this time period i had only put 7k mikes on it before it blew up. After doing tons of research there is a tons of class action law suits against Ford for these cars. The incident that occurred was while driving the vehicle caught fire on the passenger side. Driving at the speed limit of 40 MPH no warning lights, Check engine lights or anything it just blew up. Up to this point all maitence was done properly and after doing some research it had the same issue report by multiple other Shelby owners of this year. This vehicle is not safe for the roads and if not properly investigated, it can cause someone to lose their life. I incurred a bruised head, burns and loss of hair from this accident. I’ve contacted Ford in regards to this issue and yet to have anything done. This vehicle should not be sold to the public with these known issues. There was recall sent out to fix this issue but my specific vin number was never contacted to fix it.

While driving at 65mph with both heated seats on, I noticed a burning smell in the cabin. I assumed this was from an external source, but was prepared to pull over on the highway if I saw smoke, which I did not. The following day, I noticed the heated seats of my vehicle no longer worked, although the lights indicate they were on without any issue (implying power was still being supplied). I searched Google to determine if this is common, and to my disappointment, it seems that a number of ford vehicles fitted with heated seats have suffered the same failure: the power connector to the module controlling seat heating/ventilation had melted. I first checked the 30A fuses in my vehicle to see if they had blown, and confirmed they had not. I safely unplugged the affected cable on my vehicle from the seat, which required pliers because it was melted to the connector, only to confirm that my power connector had melted. I have identified that fixing this issue requires replacing the wiring harness, this can be done at home for $100 but should be done by an auto electrician. Ford appear to be quoting $700-$1100 for the same fix, encouraging individuals to undertake the work themselves without the expertise to do so. Had the scarf that was in my passenger foot well been near the connector, it's entirely plausible that this issue would have caused a fire in my vehicle and put mine and others life at risk while I was driving at highway speeds. I will make my vehicle available for assessment to the manufacturer and interested parties, and keep the cable disconnected until it is replaced. I will not pay for this repair given the issue is something that should not be a problem in the first place, and that is not expected to be part of a vehicles regular maintenance.

I smelled a burning smell when turning on seat heater. Seat heater no longer provides heat, but indicator switch light up as if heater should be on. The burning could have led to fire in passenger compartment of vehicle. I have not taken the vehicle in to have this serviced. I inspected the wiring harness and the “M” pin is clearly burnt (I have photos). There were no warning lights. I can press switch to turn on seat heater and the lights turn on as if the seat heater were working, but no heat.

Random smell of burning electrical wiring soo strong I thought the car was catching fire, I had to pull over and check for smoke but didn’t find any. A few days later I realized the heated seats stopped working… did some Research and found the plug connector underneath the passenger seat melted.

I began to smell something burning from inside my car while I was driving. After further investigation I discovered the burning smell was coming from the passenger seat when the seat heater was on. I unplugged the wiring harness to find that a pin was burning and melting the plastic.

I drove up to my gym, got out of my car, locked it as usual so nothing out of the ordinary. Went back out to my car about 30 min later and saw smoke billowing from windows... Opened my door passenger side and my glove compartment was the source so I open it and all I saw were flames leaping from the top of the compartment and flames coming outta the air vents. Within minutes the entire glove box compartment as well as the dash itself melted onto the floorboard. Some gentleman found a fire extinguisher and put it out before the fire department even arrived. Im just lucky I wasn't in it but this had to be some manufacture defect in the wiring because I believe that it started above the glove box right were the wire harnesses enter the car through the fire break between the car and engine compartment.
