2008 Chevrolet Suburban 1500 Problems

What owners report

Owners of the 2008 Chevrolet Suburban 1500 most often report dash cracks around the passenger airbag area, power door lock actuators and door handles that stop working or break, and (for unaddressed vehicles) the Takata airbag recall, where complaints centered on parts not being available. Engine oil consumption and noisy lifters also appear in the sample, usually at higher mileage. Many reports involve the interior trim and door hardware rather than the drivetrain.

   Dashboard cracks near the passenger airbag

   • 23 complaints (23%)
   • median 70,000 mi at 8.0 yrs old (17 state mileage)
   • filed 2014–2019

   Owners describe cracks appearing in the dashboard, most often at the upper corner of the passenger-side airbag cover and around the instrument cluster, sometimes with no impact at all. Complaints say the cracks grew over time and that dealers quoted several hundred to around $1,400 for a replacement dash, with one owner told a partial out-of-pocket cost would apply. Owners commonly say their concern is whether the cracked plastic could affect airbag deployment or send fragments into the cabin. Reported from roughly 25,000 to 150,000 miles, often noticed spontaneously while parked or after years of sun exposure.

   What to check: Inspect the top of the dash at both corners of the passenger airbag cover and above the instrument cluster for hairline cracks; ask whether the dash has been replaced and keep the vehicle out of direct sun where possible.

   2 excerpts from owner complaints in NHTSA records

   “The dashboard has cracked at the front left corner of the passenger airbag. It has also cracked at the instrument cluster. These cracks are extremely concerning, especially if I am in a crash. I am certain that the crack near the airbag will expand and create shards of plastic or worse, prevent the airbag from deploying properly.”

   NHTSA complaint #10788992, filed 2015-11, 105,000 miles

   “I'm a owner of a 2008 Chevrolet suburban and I have been the original owner of this vehicle. My dashboard has two large cracks and the one I'm most concerned about is the one there the front passenger side airbag. I very concerned that this could to lead to a catastrophic injury if the airbag deploys.”

   Air bags

   Takata airbag recall not completed (parts unavailable)

   • 28 complaints (28%)
   • median 120,000 mi at 8.8 yrs old (4 state mileage, few)
   • filed 2016–2019

   Many complaints are about the Takata inflator recall rather than a new failure: owners say they received a recall notice for the front passenger inflator, then were told by dealers that parts were not available and no repair date could be given. Some report repeated visits over multiple years with the same answer, and a few describe the airbag warning light or a deflated appearance at the passenger airbag. A separate report describes airbags not deploying in a collision. Reports span vehicles with no mileage listed, filed from 2016 through 2019, several years after the recall notice.

   2 related service bulletins

   What to check: Ask for written confirmation that the Takata inflator recall has been completed on the specific vehicle; a dealer can run the VIN and state whether the remedy is open or closed.

   “Takata recall - I'm the owner of a 2008 Chevrolet SUBURBAN 1500 ltz. Two years ago I received a letter saying that the takata air bags were subject to recall due to explosive hazards, but said that we should continue to drive the suburban as usual (? - does that make any sense?) and that it was illegal to disconnect them even though they might kill you if they exploded! Does that make any sense? (not to me!) I am a grandfather with two precious grandchildren. …”

   NHTSA complaint #11103535, filed 2018-06, 148,000 miles

   “Takata recall, I received a recall may, 2016 and now I received a letter november 2017 for the same recall. It tells me to go to my dealer and have this fixed for free and I did today 11/3/2017 and they tell me there is still no fix for this issue......why!! Can someone help me with this so it can get fixed, I don't want to get in an accedent and find out the hard way that someone dies because this was never taken care of. Why did I just get this letter and still no fix comes up. …”

   Latches, locks and linkages

   Power door locks and lock actuators stop working

   • 13 complaints (13%)
   • median 37,500 mi at 3.1 yrs old (12 state mileage)
   • filed 2008–2013

   Owners report power door lock actuators failing one door at a time, so doors will not lock or unlock with the switch, remote or automatic locking, and the rear doors sometimes have to be opened manually from inside. Complaints describe repeated replacements, quotes of roughly $90 to $400 per door, and dealers saying the part or wiring for the 2008 design was no longer available. A few reports link the lock cycling to electrical glitches such as flashing gauges and a radio clock that resets. Mostly reported between about 4,000 and 85,000 miles, with several owners seeing failures within the first few years of ownership.

   What to check: Cycle every door lock with the switch, the remote and the automatic lock while driving; check that each door locks and unlocks reliably and that the interior handles open from inside.

   “Have replaced 3 electric door locks, each several months apart. I transport several of my grand kids and assume that I have locked the doors with my automatic lock only to find out the plugger is not working. This could lead to one of my children opening the door and following out.”

   NHTSA complaint #10392357, filed 2011-03, 37,000 miles

   “Left and right rear exterior door handles broken/inoperable. Those were removed and replaced at dealership, but at half price (parts and labor) since I had gone over the 36,000 mile warranty. Since that time, I have had all four mounts on exterior door handles break making it necessary to open the doors very carefully so that the handles do not break off completely so I can open the doors. Also I have had to replace the actuators on the driver's door and the left rear door. …”

   Body and structure

   Chrome door handles break or peel and cut hands

   • 9 complaints (9%)
   • median 50,000 mi at 3.8 yrs old (9 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2010–2016

   Complaints describe exterior door handles breaking off at the plastic mounts and interior chrome handles whose plating lifts and leaves sharp edges that have cut fingers. Owners say the dealer had seen many similar cases and, in one report, pointed to a service bulletin on the handle design, while others paid half price or full price for replacements. Several reports note that the same problem appeared on more than one door. Reported from about 20,000 to 88,000 miles, often on multiple doors over a period of months or years.

   What to check: Open and close each door from the outside and run a hand along the interior chrome handles to feel for lifted or sharp plating; ask whether any handles have already been replaced.

   “I cut my finger on the interior passenger side door handle when exiting my vehicle last weekend. The metal lifted, making an extremely sharp edge. I emailed Chevrolet on saturday in the early afternoon, but have not heard back from them yet. This is very dangerous, and I am not sure how to proceed. Thank you for your help!”

   NHTSA complaint #10576124, filed 2014-04, 88,400 miles

   “Both driver side and front passenger side chrome plating on door handles peeling off. My finger has been cut multiple times by the peeling chrome . The cut is similar to severe paper cut. My husband has also cut fingers on the door handles. I have two very small children and worry about them cutting their fingers on it.”

   Engine

   Oil consumption and lifter noise on the 5.3L V8

   • 6 complaints (6%)
   • median 94,375 mi at 6.7 yrs old (6 state mileage, few)
   • filed 2013–2018

   Owners report the engine using a quart of oil every 1,000 to 1,500 miles between changes, with one saying a service bulletin procedure did not reduce it. Others describe a tapping from the engine that was traced to camshaft lifters, in one case breaking repeatedly within a few hundred miles and leading to an engine replacement. Complaints also mention rough running, a misfire and an engine mount replaced several times. Usually reported above roughly 40,000 miles, with lifter failures appearing closer to 90,000 to 120,000 miles.

   2 related service bulletins

   What to check: Check the oil level and look for a fuel or burnt smell on the dipstick, listen for ticking at cold start, and ask for oil change records showing how much oil was added between services.

   2 excerpts from owner complaints in NHTSA records

   “This engine is burning 2-3 quarts of oil in between oil changes (car has less than 50,000 miles on it). This is the only car I have had in 30 years that burns this much oil. I am constantly adding new oil to this engine and still having to change the oil regularly in order to stay in compliance with the manufacturer's warranty despite refilling half of the oil with new oil between changes.”

   NHTSA complaint #10778808, filed 2015-09, 42,693 miles

   “Excessive oil consumption of the 5.3l engine. It 'burns' a quart of oil between 1100 and1500 miles. The TSB issued on the engine fixed nothing. Chevy said they won't do any more which is indicative of the corporate culture at chevy. This has been an ongoing problem.”

   NHTSA complaint #10870585, filed 2016-05, 14,000 miles

Buying note. Look at the dashboard around the passenger airbag cover, test every power door lock and handle, and confirm in writing whether the Takata airbag recall has been completed. On 5.3L trucks, check oil level and service records and listen for lifter noise before buying.
