2012 Chevrolet Suburban Problems

What owners report

Owners of the 2012 Chevrolet Suburban most often report a cracking dashboard — typically starting at the passenger-side airbag area or above the instrument cluster — sometime between roughly 20,000 and 100,000 miles, and many describe it worsening over months or years. A second recurring theme is the dashboard airbag warning light coming on intermittently, along with complaints about interior door handles and a sputtering or stalling engine.

   Cracked dashboard around passenger airbag and cluster

   • 52 complaints (51%)
   • median 68,000 mi at 5.6 yrs old (41 state mileage)
   • filed 2015–2022

   Complaints describe cracks appearing in the top of the dashboard, most often at the passenger-side airbag cover and above the instrument cluster; several say the cracks start small and spread until the panel separates or rattles. Owners frequently mention the possibility of sharp plastic near a deploying airbag, and some report the repair quoted in the hundreds to over a thousand dollars, with coverage often declined as outside warranty. A few mention the dashboard was replaced and later cracked again. Appears from roughly 20,000 to 100,000 miles, often after several years and frequently on vehicles kept in sunny climates.

   What to check: Inspect the top of the dash carefully at the passenger airbag seam and above the gauge cluster for hairline cracks, and ask whether the dash has been replaced or repaired.

   “I got in my car saturday morning, october 1 and noticed 2 cracks on the driver's side of my dash board. Upon research I have discovered this is not an isolated incident. I am concerned about the safety of having this get larger and exposing electrical/mechnical components and the sharp edges of the cracked plastic should an accident occur. …”

I was warned after I purchased vehicle that it was a safety hazard in event of airbag deployment. I am reporting the date as the date I purchased vehical but crack was present prior to that date for an undetermined period of time.”

   Engine

   Engine stalling and electrical power interruption

   • 10 complaints (10%)
   • median 59,500 mi at 3.5 yrs old (10 state mileage)
   • filed 2014–2018

   Complaints describe the engine cutting out while driving, with the dash lights, radio and door locks cycling on and off at the same time; some vehicles restarted after several attempts and others did not restart until later. Dealers in several complaints could not reproduce or diagnose the fault, and a few owners also report a fully dead battery after the vehicle sat undriven for several days. Typically reported between about 30,000 and 100,000 miles, during normal driving rather than at first start.

   What to check: Ask whether the ignition recall was performed, check for stored codes and battery/charging history, and note any flickering dash lights during a test drive.

   “On two recent occasions my Suburban has failed to start (battery dead). I went to an auto parts store, they tested the battery and said it was good. Why is my battery going dead? Both instances are the vehicle is set on accessories and the radio was working. In both instances the battery would not turn over the engine.”

   NHTSA complaint #10650534, filed 2014-10, 40,000 miles

   “While just starting to accelerate, the radio shut off, the automatic locks started to go up and down, then the engine light came on and the engine stopped running. I put the truck in park, shut of the engine and restarted without issue 5 minutes later. Two days later, the same thing happened, only this time, when we went to restart the truck, it seemed as though the battery was dead as no dome lights would come on and the fob would not work the door locks. 3 hours later when the tow truck operator showed up, the truck started right up. …”

   Air bags

   Airbag warning light on intermittently

   • 20 complaints (20%)
   • median 66,000 mi at 5.6 yrs old (19 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2015–2021

   Complaints describe the airbag or service-airbag indicator lighting up and going out at random, sometimes repeatedly over months or years. In one case a dealer found a loose connector under the passenger seat and made repairs, but the light returned; other owners say dealers could not reproduce the condition or retrieve a code. One complaint describes side curtain airbags deploying while the vehicle was parked and idle. Reported across a wide mileage range, from very low miles to over 120,000, with no clear pattern in the complaints.

   Recall 21V051000Recall 21V054000

   What to check: Check that the airbag light comes on with the ignition and goes out; if it stays on or flickers, have the airbag system scanned and confirm any open recall was completed.

   “An airbag icon warning light keeps apprearing and disappearing on the dashboard. This has been going on for a couple of years. I believe that there is a defect in the airbag system but my vehicle does not appear to have a recall as of now. This happens almost every week at all times.”

   NHTSA complaint #11047837, filed 2017-11, 200 miles

   “The airbag error indicator on the dash activates frequently, especially after driving several hundred miles in one day. When the error message is activated, the backup camera image is pixilated. It does not do it when the vehicle is in park. Chevrolet service technicians have been unable to recover the error code or replicate the error message. This is a continuing problem.”

   Interior door handles and liftgate latch problems

   • 11 complaints (11%)
   • median 75,000 mi at 4.3 yrs old (9 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2014–2024

   Owners report the interior door pull handle or grab bar breaking during normal use, with the fix usually being replacement of the whole interior door panel. Others describe the rear liftgate lock acting intermittently, sometimes staying locked or ajar with no manual release or key access; one complaint says a dealer traced it to a failed liftgate lock actuator. Mostly reported between about 60,000 and 100,000 miles.

   What to check: Open and close each door several times and pull the interior handles firmly to check for looseness, and cycle the liftgate lock remotely and manually.

   “Fl door ,pull handle gets broken real easy and every time we need to change the whole door panel.the door pull handle material is poor and after few times pulling the door it gets broken.we have heard same story from lots Suburban or tahoe owners.”

   NHTSA complaint #11041604, filed 2017-10, 65,000 miles

   “Interior driver door handle grab bar is broken. Rigid plastic pieces under the upholstery broke and now the handle is falling apart and loose. This is an integral part of the armrest. Handle broke using normal closing force, and apparently this is a large, well known problem. Chevrolet has no repair for this problem other than replacing the whole interior door panel and the cost is around $600.”

Buying note. Look closely at the dashboard for cracks before buying, confirm any open airbag, ignition and steering recalls were completed for that VIN, and take a longer test drive to watch for dash lights flickering or the engine cutting out.
