Other lighting problem on the 2006 GMC Envoy
When other lighting problem gets reported
Owners of the 2006 GMC Envoy report other lighting problem at a median of 105,000 miles. A quarter of the reports come in before 85,000 miles and a quarter after 120,000 miles, from 14 reports that carried an odometer reading.
A part like this is normally expected to survive 86,000 miles. It is the 7th most-reported problem on this model year.
The mileage distribution
The reported range runs from 65,000 miles at the tenth percentile to 155,000 miles at the ninetieth, a spread of 89,652 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 |
|---|---|---|---|---|
| 65,292 miles | 83,920 miles | 105,225 miles | 118,875 miles | 154,944 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 $120–$1,200 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 2002, at a median of 50,000 miles, and latest on the 2003 at 135,000 miles.
By volume the 2007 carries the most reports, with 32; the 2006 has 20. 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.

Tl* the contact owns a 2006 gmc envoy. The contact stated while driving 70 MPH, the headlights failed. Th contact took the vehicle to the dealer who advised that there were no recalls for the vehicle. The vehicle was not repaired. The manufacturer was notified who advised that she take the vehicle to the dealer for a diagnostic test and offered no further assistance. The VIN was unavailable. The failure mileage was 36,000 and the current mileage was 94,000.
One evening I was driving on the main highway and my inside lights came on. I pulled to the side of the road to check the switch but it was on auto. I turned it off but the lights stayed on. They were still on when I got home and parked turned off the ignition the lights were still on. The next morning my car couldn't start because it had ran my battery down. Another incident was my headlights went off one night while I was drive on the highway. I am also having problems with my gas gauge. My gas light comes on like I am out of gas. The last time I fill my car up with gas it hesitated. It didn't want to start. The light stays on when my car is full of gas. I smell gas. I sat at the gas station for an our because my car didn't want to start. The sound of my radio goes in and out. My lights continue to go on and off when driving or when not driving. One morning I got up to go to work, went to start my car and the headlights were on but the switch was off. I couldn't get the lights to go off when I got to work. They stayed on at least for 4 hrs. Sometime the lights doesn't come on when I put them on. I really have some weird things…
Headlights go out. Has happened several times while driving and 1 time would not come on when vehicle was started at night. If we had not had fog lights, we could have a bad accident or at very least been stranded on the side of the road. *tr

How far this goes
Complaints are voluntary, so 20 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

How common is other lighting problem on the 2006 GMC Envoy?

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.
