Misfire or rough idle on the 2014 RAM 1500
1 crash 1 injury 2 of the 23 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When misfire or rough idle gets reported
Owners of the 2014 RAM 1500 report misfire or rough idle at a median of 130,000 miles. A quarter of the reports come in before 110,000 miles and a quarter after 140,000 miles, from 14 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 24th most-reported problem on this model year.
The mileage distribution
The reported range runs from 70,000 miles at the tenth percentile to 155,000 miles at the ninetieth, a spread of 80,871 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 71,929 miles | 112,300 miles | 130,304 miles | 138,152 miles | 152,800 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Of these reports, 1 a crash and 1 an injury are mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
Putting it right typically runs $250–$1,600 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 8 model years of this car. It shows up earliest on the 2022, at a median of 20 miles, and latest on the 2014 at 130,000 miles.
By volume the 2014 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
2014 ran 1500 tradesman blacked out edition. After stopping the vehicle and putting in park to check other concerns when running 40mph the truck shakes and sounds like misfire, after stepping out of truck it began to roll backwards and pushed me down. After getting back up the truck continued to roll down the hill and ran over my ankle and foot. Before crashing into a concrete wall. Since then I have used the emergency brake when parking and the truck was repaired by insurance. 8,000 dollars of damage to the truck and my right foot is still healing after 2 months. Dash showed truck in park and lever was completely up. This is the 2nd time it happened, and I got lucky the truck didn't run over my chest or head. The first time the truck didn't stay in park was probably about 7 months ago, I placed truck in park and began to get out when the truck was still rolling forward. I had to push on brakes and remove from park and put back into park for it to work. Intermittent park position is a very bad thing to be intermittent.
Driving down highway came upon another vehicle doing 40mph decide to pass this driver. As I passed the driver at about 60mph when I let up on the gas pedal it went to the floor on its own and excelerated to 95 MPH I was on the brake to try and slow the vehicle and after about 5-10 seconds the gas pedal returned to the normal position and vehicle then slowed down. A light illuminated on the dash and according to the user guide the light is the electronic throttle control light. In the description of the problem it states that "you may experience reduced performance, an elevated/rough idle" it seems that ram already knows of this problem with the elevated idle the book just doesnt state that the elevated idle can increase when the vehicle is being driven or in drive
My truck has started running rough without any power and noticing a tickingkocking noise within the past week so I started looking into it as I've always changed my oil between 5-10k full synthetic 5w20 and always ran good fuel at least 89-93 bc I have 142k on it. I've noticed the ticking noise around 75 and thought maybe slight exhaust leak from the welds but as I start reading on internet it's been a problem with chrysler on all these hemi engines for quite a few years now and I think it's bs that I'm having to pay to fix something that obviously been a problem for vehicles with well under the mileage I have as well. The wife has a chevy with over 200k that rubs like a top and she never changed the oil before we got together, in fact it was sludge when I did the first oil change and it doesn't tick nock or hesitate one bit. I hope someone will step up and help ppl out with their mistakes and make it right bc I'm out of a vehicle I still owe on and can't even get to work bc guess what I drive for work. Bummer I know but not if y'all would fix problems when the arise!!!!

How far this goes
Complaints are voluntary, so 23 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does misfire or rough idle happen on the 2014 RAM 1500?
Across 14 owner reports that included an odometer reading, half were filed by 130,000 miles. A quarter were filed before 110,000 miles and a quarter after 140,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is misfire or rough idle on the 2014 RAM 1500?
23 reports have been filed with NHTSA, about 0.2 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
