Three reasons that 2016 Ram 1500 owners should be worried about their fuel sensors

The owner of a 2016 Ram 1500 is concerned because his fuel sensor light came on unexpectedly. Members of a truck forum point out that this problem is happening quite frequently.

There is nothing more worrisome than the thought of being stranded in the middle of nowhere with vehicle trouble. That was the cloud hanging over the head of a 2016 Ram 1500 owner. Mollie, from Arizona, told members of a Ram truck forum, “I have a 2016 Ram 1500 Longhorn and tonight I filled the tank and about 100 miles later the engine light came on (solid) and the fuel gauge went to empty and the fuel range went to low fuel. Called Ram customer care and a case was opened and they suggested I get hold of the dealer. I will contact the dealer but I'm 60 miles from the dealer and I'm concerned if I can drive that far with these warning indicators. Any else have this problem?”

Engine lights often signal long term consequences

Most of us have learned over the last few years that a “check engine” light can mean bad gas, but a solid engine light is a different animal and no one wants to do long term damage to a vehicle. Plus, having the fuel gauge drop would suggest a major leak and the possibility of a fire.

Service department admits this is a known complaint

Mollie checked in with Ram customer care and was surprised at the response. “Talked with customer care today and they opened a star case, also spoke with dealer, also spoke with tech and set up appointment for Monday morning. Tech said they have had several issues like this lately.”

Fastback says it happened to him, in Texas, repeatedly. “I had that happen intermittently for months. Finally they filed a STAR case on it, and eventually the fuel pump was replaced. I haven't seen the issue since.”

Marsh had it happen, in Long Island, as well! “I had the same issue, turned out to be the fuel sensor, dealer replaced and corrected the issue.”

Replacing the sensor is expensive

Mollie told members of the group that his dealer appears to have solved the problem. “The dealer removed the fuel tank and replaced the fuel pump assembly, all is well now just hope that I have no more fuel pump issues.”

Mollie is lucky that his vehicle was still under warranty and they fixed the problem. Most people don’t know that most of the fuel sensors are now part of the fuel pump assembly, so to fix a problem like this they have to change the fuel pump. That means they have to drain the fuel tank, remove it and switch out the fuel pump. It takes almost a whole day and can run close to a thousand dollars. So if you start to develop problems try to have it taken care of under warranty, waiting can cost you a bundle. I have not seen many complaints from other Ram model years, but if you own a 2016 Ram 1500, it is good to be aware.

I have a 2015 1500 5.7Long Horn with about 45K, and am now getting the dredging fuel sensor failure, luckily I got the extended warranty (which I sadly now see to have to suggest with this truck), there was also a plugged sensor they replaced awhile ago also and does any one have a problem with the brake pedal being loose?

I have the same problem with my 2016 Ram truck . The fuel gauge goes on and off, it hard to tell how much gas you have. I have three friends that have the same problem with their Ram 2016 Trucks also. This problem should be a recall.

I have a 2017 Ram 1500 with only 5000 miles on it and the sensor appears to be bad... not a good sign...
kind of sad but the day I got it brand new and brought it home the battery went dead with a bad cell... I had to get help to get it started to take back to shop to get new battery... brand new and dead... now 5000 miles and a fuel sensor bad...WOW!

Well guess that happens more often than I thought. I had to have a jump start 4 times in the first week I owned my 2016 truck. It has also had 4 recalls fixed and now the fuel sensor is going out. Thank God for extended warranty.

This is a problem I'm also having this problem with my 2017 dodge ram. Why isn't this a recall. I guess we as owners need to make some noise or dodge fix this issue . I will definitely be making some noise .

2014 ram. Started same problem at 40k miles. Fuel gage reads fuel system failure and check engine light comes on, stays on, and fuel gage works. I think on the arm of the float, there’s a sensor that reads from a “metallic” contact strip. Debris in the fuel wears a mark that makes the sensor read “OL”, or open loop meaning it’s not reading or making contact. I’ve researched this a lot, and if you get a new fuel pump, DO NOT get a mopar. You will get a new pump same design and about 10k miles if you’re lucky, you’ll get the same issue!! Make your mechanic show you the pump and make sure it’s the “new” design. It’s crap, no matter what, you’re looking at a whole day diy, and about 800-1000$ for a mechanic to do it. I already fixed a freakin leak around my brake light over the back window. If you find a person from Chrysler we can explain this issue with to MAKE NOISE!! I want in.

2018 RAM 2500, 7k miles. A full tank maxes out at half full on the gauge. Just started doing it a few 'tanks' ago. I'm afraid to go far when it is probably half full of diesel but shows range of 0 miles.

2015 Ram 1500 HEMI 70K at 1/2 tank FUEL SENSOR FAILURE. after about 3K miles NOW its on all the time. No problems tough. Runs good after 5K miles. But it wont pass inspection now. So i guess im screwed. I cant afford a FORD so i settled for a RAM. Now i guess its time to pay the piper. Where do you go to demand a RECALL.

Sitting in dealer now with sensor fail and no gas tank reading. Drops at three fourths tank. I'm reading this happens a lot. No more dodges for me. I may choose not to fix it and trade it in. Hopefully GMc Or ford won't have this problem.

JUST DRIVE IT - My 2015 Ram Hemi 70kmi - FUEL SEN FAIL. If you dont have warrenty or a $.GRAND.$ laying around , just use your ODO. I fill up then i track my mileage and fill up again at 300 miles or less.I run 50m/day. everyday. No Problem. Fuel Pump works fine. Gauge just reads 0. Inspection in April. I'll fix it then. Unless their is a miracle RECALL first. NO CHANCE.
