Other engine problem on the 2011 GMC Sierra 1500
When other engine problem gets reported
Owners of the 2011 GMC Sierra 1500 report other engine problem at a median of 40,000 miles. A quarter of the reports come in before 20,000 miles and a quarter after 85,000 miles, from 11 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 4th most-reported problem on this model year.
The mileage distribution
The reported range runs from 15,000 miles at the tenth percentile to 105,000 miles at the ninetieth, a spread of 92,408 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
36% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 13,592 miles | 20,500 miles | 40,000 miles | 86,075 miles | 106,000 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
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 27 model years of this car. It shows up earliest on the 2026, at a median of 1,700 miles, and latest on the 2000 at 190,000 miles.
By volume the 2021 carries the most reports, with 129; the 2011 has 12. 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.
Tl* the contact owns a 2011 gmc sierra 1500. The contact stated that while driving approximately 55 MPH, the contact heard a loud rattling noise outside of the vehicle. The vehicle was taken to an authorized dealer for diagnosis. The technician stated that the failure was contributed to the engine lifters which were replaced; however, the noise persisted. The vehicle remained at the dealer for further investigation. The manufacturer was not notified of the problem. The approximate failure mileage was 13,592.
Started truck up and let idle for two minutes. Upon take off, the traction control light came on and was immediately followed by the check engine light with a message stating engine reduced power. The truck then begins to run very rough and when the brakes where applied it violently and uncontrollably lunged forward. I pulled off the road, turned off the engine, and waited a minute or two. Upon restarting the engine, the check engine light came on but the reduced power message and traction light where gone. After sitting at a light for a few seconds, the symptoms where back, nearly causing me to rearend the vehicle in front of me. I pulled over again, turned off the engine for a minute, restarted and the same results as before occured. Now this happens every time the truck is running and sits in the same spot for more than two or three minutes. *tr
Noticed one morning when starting up my truck the valves were tapping. Like out of adjustment. My 5.3 is roller lifters so I was surprised. Took it to dealer and was told that gm had a recall on cadillac, chevy and gmc 5.3 and 6.2 engines with defective lifters. Dealer replaced the lifters. Took a week. When I picked up truck service adviser told me to expect to come back around 60k for a new camshaft. Now what! *tr

How far this goes
Complaints are voluntary, so 12 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 2011 GMC Sierra 1500?
Across 11 owner reports that included an odometer reading, half were filed by 40,000 miles. A quarter were filed before 20,000 miles and a quarter after 85,000 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 2011 GMC Sierra 1500?
12 reports have been filed with NHTSA, about 0.4 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.
