2015 Colorado, Crew Cab, Long Bed, z71

4wd, V6

135,000 miles

Original owner

A big stack of recall/service advisory type items that mostly hit the 1st year or two.

Battery
Alternator
Tranny mount
Leaking right rear axle seal
New rear brake pads

And I think that's about it.

 

Damn, that is a lot of issues, but a LOT of miles in 4 years too.

 

I wouldn't consider those a "lot of issues", the tranny mount failed early and was easily repaired for free at the dealership.

It seems the alternator and battery deaths were connected and caused by an bad diagnosis.

Brakes at 110,000 sounds good to me.

The axle seal is of course not a unexpected Chevy issue, but again, at over 100,000 miles when it happened, not a complaint.



Very happy with this truck, in fact it's going to Africa next year.

I have a 2015 V6 RWD CCLB that was manufactured in November 2014. Here is a quick list of the things I saw:

- Check engine light on day 2. Cause was the bed crushing a vacuum hose against the frame (assembly issue from the factory). Hose replaced and correctly routed, no follow up issues
- Squeaky airbag on steering wheel. Shimmed by service center, and never heard it again.
- No heat (happened 2 times) due to a faulty mixer valve (ultimately became a TSB). Final fix was to use a hose clamp to reinforce the valve. No issues since.
- I've had the chuggle and reluctant throttle issues. There is a new TSB to reflash the computer to fix the shift points and throttle response. I plan to have the dealer perform the update based on the good response from other users on this forum.
Read through this thread: https://www.coloradofans.com/forums...calls/396411-gm-has-fixed-2015-16-transmission-service-bulletin-18-na-14-a.html
- Brought the truck in for assorted other recalls (wiring harness chafing, brake caliper leak, seat attachment, hood striker, power steering, etc.). None of these were actual issues on my truck, just checked per the recall and ok'ed by the service adviser.

I attribute everything above to being first model year issues. Also, everything mentioned above was within the first year.
It seems like the kinks have been worked out for the most part. You can have your local chevy/gmc dealer run the VIN and make sure that it has had all of the recalls applied. If not, they should be free to get checked out.

I've got 45,000 miles on the truck so far, and I'd say it has been reliable. I still love it.

 

2016 3.6gasser with 17K. (3 years old this coming November)

Only problem Ive had is keeping my wallet filled with all the stupid stuff Ive done to mine.



Note....if mine got stolen tonight, Id go buy the identical truck tomorrow....... zero regrets or issues.

 

True, can't really fault a battery failing in 4 years, I'm lucky to get 2 out of any battery where I live.

 

After 2 years and 45k miles, my main issues have been an infotainment system that needed replaced (just before warranty expired) and my fuel door cover that came off and got lost while driving that cost me $100 to replace (included painting). Will be getting first new set of tires this fall. 50k on the originals isn't bad, IMO. Brakes still going good. No other problems.

 

2.5 yrs and 40k miles been in shop every 4 months for various issues from transmission shifting to dead batteries to idiot lights flashing, NAV taking me places that dont exist, too much air in the tires, fuel tank wont stay full, headlights always stay on...believe it or not

 

2016 V6, CC, 4x4 20k miles

20k is not a whole lot of miles but Zero problems.

Should I go knock on wood now???

 

2015 Canyon, 71K miles, Built around January, 2015, so an early truck.

Had the Electronic Power Steering rack fail, replaced in first 45 days or so.

Hood Flutter issue resolved.

Solenoid Purge Valve replaced right outside of warranty - so I need to get the refund on that one from dealer.

Replaced battery pretty quick, maybe 2 years?

Replaced original tires at 69K.

The acceleration issues seem to come & go, seem worse last few weeks. Heat may make problem worse?

Driver seat leather cracked the other day where it gets compressed along the side: I knew when I slid out the way the seat collapsed it was going to crack the leather.

Likely to replace rear bumper in next few weeks after the guy rear ended me.

Other than that, changed oil, changed transmission fluid, changed diff fluid. May consider radiator flush.

Changed air filters: Reminding me that I need to check both the engine and HVAC filters soon. Maybe I will get up real early one morning.

 

2017 Colorado



Currently 18800 miles. Purchased in March of 2017.


Knock on wood. Really no major issues. Very pleased with this truck.

 

22,000 miles. Had the trans flashed twice to fix the shuddering and driver's seat cover replaced because of small tear at one of the seams. That's it. So far so good. Looking to get another 100,000 miles out of it.

 

28000 miles.

A couple ECU flashes at dealer regarding error code sensitivity.
Infotainment update at dealer to resolve black screen/lockup.
Dangling/loose/chafing wiring harnesses that I corrected myself.
Numerous rattles I corrected myself.
The shocks seem a little lazy for 28k miles.
A number of other things I adjusted to my preference but wouldn't call a defect.

 

Leased Feb. 2015 (after purchasing 3500 lb. travel trailer Sept. 2014). Never owned a domestic brand, let alone a pickup truck.

-3k Front seat hooks recall
-9.7k Air conditioning failed while towing on a hot, hot interstate in July—no problem found and has never re-occurred (2015)
-14k Power steering assist recall
-19k Trailer hitch recall inspection (all good)
-26k HVAC module temp door recall
-31k Replaced 1 license plate light
-45k Replaced purge solenoid after engine light warning
-49k Replaced rear brakes and rotors + 50k service incl. transmission fluid change (that was an expensive day)
-51k Replaced OEM tires last month
-Had the hood flex looked at (well documented here) but I never showed up to claim fix kit when it arrived at dealer
-Engine stalled twice within a few months shortly after starting in 2016—dealer adjusted idle and no re-occurrence since
-Replaced air dam after parking-by-feel incident

Dec. 2017 purchase truck outright. As you can see, more Chevy-induced recalls than any real (or self-inflicted) problems. This vehicle has been an absolute joy to own.

 

2018 Z71. Transmission shifting poorly and shuddering, Tire pressure sensor system failure (at 25miles on the clock). Complaint now is the drive by wire "hesitation".

 

mine was built 10/31/14 and I took it from the dealer on November 14th. I've got the same truck you're looking at: 2015 V6 SLT CC LB.

So far I've got 36k miles on the truck and, although I was apprehensive about a new model year purchase, I have to say I don't regret it one bit. Much of my long miles have been in the high heat & humidity here in Central FL. I was in an accident last october so I've got a new Right wheel, fender, headlight and some of the other things, but the damage was just cosmetic. I just had to have my touchscreen replaced, and a few squeaks & rattles fixed but nothing major. I also have a knocking in the engine (at least that's what it sounds like), but they tell me it's nothing and it's fixed/quieted by using a higher octane or upping my mileage/week. Go figure.

Overall, a great truck although I haven't put on many miles yet.

 

I am surprised by the guys/gals with the 14/15 versions as those had a notorious issue with blowing that one oil line. I suppose the ones that commented had that replaced as a recall but I hadnt noticed it being mentioned.

 

2017 Z71 V-6, CCSB, 18000 miles. Had a slight noise in the A/C that was corrected a while back. Recently, the transmission shudder was corrected as well. Aside from that, I love this truck.

 

'16 with 30,000 miles. No problems. It leans a bit but now they have a fix for that.

 

2015 WT 2.5L manual (Jan '15 build), 46,000 miles and so far I haven't had a single issue with mine. Broke 2 rules in buying a new car and buying a 1st model year on top of it, have nothing but good things to say about the truck though.



There was a recall shortly after I got it for some component of the exhaust that I can't remember, the dealership replaced the whole exhaust. I also had a cab controller flashed per a TSB. That's the only time it's spent at the dealer in 3.5 years.

 

I've had the rear brakes done per the TSB that the dealership brought up to me when I had the truck in for the TSB install of the ECM and trans recently. That's about it when it comes to problems, I did have them look at the noisy rearend and they showed me a 2018 makes the same noise, so it is normal, albeit crazy in my opinion. I found out how to eliminate the noise from the rear leaf springs this past fall by putting some vinyl cove pieces between the leafs, front and rear, noise gone.

 

2017 Canyon Denali DMAX with 18,000 miles (bought new Nov 2017).

- Rear turn signal bulb bad from the factory.
- Had an airbag warning pop up after a couple of months of ownership, turned out to be a known issue with the harness at one of the connectors.
- Seat ventilation fan in driver's seat back failed (bearing, making a buzzing sound). Goes in tomorrow to be replaced.
- Pandora app in the infotainment system randomly causes the DIC screen to spaz out. Known issue but no software fix yet.
- Apple CarPlay can sometimes be a pain to launch. Not sure if it's an issue with the infotainment system or with iOS. No fix yet.

Overall very happy with the truck, other than the airbag harness issue the others are barely worth mentioning.

Apparently I haven't updated this thread in a while.

I'm at 88k now...

• Rear parking brake shoe friction material detached from the metal plate a couple years ago.
• Lost 3 out of the 4 studs that mount the cat to the turbo outlet, thankfully not much of a pain to repair but it was a pain to locate the source of the weird exhaust noise and random raw diesel exhaust smell. That was around 78k miles or something.
• Still had random raw diesel exhaust smell during cold startup in cool/cold weather, thought it was just carbon causing a poor seal once I took care of the above (without removing/replacing/cleaning the gasket), turns out I had loose exhaust manifold nuts for the #1 cylinder. Repaired while camping in Colorado and suddenly no more random exhaust smell, plus my exhaust brake started working well again, throttle response was better, got some power back, regen interval decreased, and DEF consumption decreased. Low/slow boost = excessive soot = more regens and DEF consumption.
• Replaced my rear brake pads at 80k miles.
• Had a leaking axle seal that developed around 78k miles.
• Had a leaking t-case input seal that developed around the same time as the axle seal leak. Strange.

I think that's it? Definitely some hiccups along the way but I still love the truck and all things considered it's been great, I haven't abused it but I haven't been too easy on it either.

 

2017 2.5L ccsb only problems I have is the water noise in the dash and I have a small water leak on the driver side I get very little water in will get both fixed here in a few months when it goes in for it’s second oil change

Both minor problems that will get fixed under warranty

 

2017 3.6 v6, 8-speed, Z71 CCSB here...I'm about to hit 38,000 and have had zero issues with the truck. Really love this truck. Some quirks with the transmission "shudder" in my truck, so I got the Trifecta tune, which helped a good bit. The 8-speed can be a little clunky at times, but the majority of the time is really smooth.

I'm regularly getting 23-24 mpg in this truck, which I think is awesome...got 27 mpg on a trip to the Outer Banks this summer. I only lost about 5-6 mpg over my 2010 Mazda3 going to this truck, so I love that.

 

On going metallic rattle in B Pillar. Taken to different dealerships and no fix and Chevy has no TSB.

Built 11/17--- 18 Chevy Colorado LT Crew Cab V6

 

Only had one problem with my 2017 Colorado LT, but it was a big one. At around 8700 miles an exhaust valve spring failed and ruined the engine. Needless to say I was a little bummed! See the story here...

Anywoo, local dealer put in a brand new engine and the truck has been great since. Other than the engine failure it's been perfect. Of course, now I'm deathly afraid of putting a tune on this engine.


15,XXX miles now and no issues. No rattles, chuggle, glitches, etc...
