When other engine problem gets reported

Owners of the 2014 Acura MDX report other engine problem at a median of 10,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 40,000 miles, from 14 reports that carried an odometer reading.

A part like this is normally expected to survive 95,000 miles. It is the 2nd most-reported problem on this model year.

The mileage distribution

The reported range runs from 2,400 miles at the tenth percentile to 85,000 miles at the ninetieth, a spread of 83,541 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.

64% of the dated reports were filed under 36,000 miles.

The whole distribution

Percentiles of the 14 odometer readings owners gave.
10th25thMedian 75th90th
2,359 miles 3,200 miles 12,250 miles 40,000 miles 85,900 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, 2 a fire is 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 $300–$4,000 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 24 model years of this car. It shows up earliest on the 2014, at a median of 10,000 miles, and latest on the 2006 at 135,000 miles.

By volume the 2016 carries the most reports, with 85; the 2014 has 18. A mode that appears across most years of a model is usually a design choice rather than a bad batch.

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.

I have a major safety issue with my 6 month old mdx (less than 5000 miles). The car is making grinding noises and vibrates, intermittently. The dealer has dismissed my claims and made minor modifications with insulation, and hoodclips. Nothing has been done to determine the cause of the problem and they pretend that there is nothing wrong, even though the service manager has heard it on more than one occasion. The care has been brought to the dealership four times over the course of the past 6 months and they have held my car in service for over 30 days. When we attempted to pick up the car last night, there was now a new extremely loud noise with every time I attempted to brake. The on-duty sales manager heard the noise and insisted that I leave the car for service. Today, the dealership is refusing to address this new issue, and still ignoring the old issue, which was caused while my car was in their service department for the past month. The car is unsafe to drive and I feel taken advantage of by acura. The dealership is also saying "their hands are tied." I have attempted to call their national customer service line and they…

This is the third incident of unintended engine revving with this vehicle. This third incident occurred at 5925 miles. Was pulling out of a parking space in "reverse" and came to a complete stop with my foot firmly on the brake pedal when, in an instant, the vehicle unexpectedly revved up while I was still holding the brake pedal firmly and shifting into drive. The vehicle jolted into drive. *tr

How far this goes

Complaints are voluntary, so 18 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 other engine problem happen on the 2014 Acura MDX?

Across 14 owner reports that included an odometer reading, half were filed by 10,000 miles. A quarter were filed before 5,000 miles and a quarter after 40,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is other engine problem on the 2014 Acura MDX?

18 reports have been filed with NHTSA, about 0.3 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.
