2008 Chevrolet Tahoe Problems

What owners report

Complaints on the 2008 Chevrolet Tahoe are dominated by a cracked dashboard, especially around the passenger airbag cover, which owners say appeared with age and often in vehicles kept garaged. Door lock actuators and scattered electrical faults are the next most common themes, and most of these reports come in between roughly 30,000 and 120,000 miles.

   Cracked dashboard, especially around the passenger airbag

   • 136 complaints (26%)
   • median 84,000 mi at 8.3 yrs old (95 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2011–2021

   Owners describe cracks forming in the dash above the instrument cluster, along the defroster edge and around the passenger airbag cover, sometimes splitting open on start-up or while driving. Many say the vehicle was garaged and had a sun shade in use, and that the cracks spread over time. Complaints describe dealers and the manufacturer declining to repair the dash, often citing warranty or normal wear, and some owners express concern about how the airbag cover and plastic fragments would behave in a deployment. Reported from roughly 25,000 to 180,000 miles, often described as developing gradually with age on garage-kept vehicles.

   What to check: Inspect the top of the dash in daylight for hairline cracks near the defroster vents, the gauge hood and the passenger airbag cover. Ask whether the p ash has ever been replaced or repaired, and check that the passenger airbag indicator behaves normally.

   2 excerpts from owner complaints in NHTSA records

   “While driving 65mph on the interstate in very good driving conditions, I heard a loud pop and realized that my dash had cracked. The crack originally stretched 6-7 inches from the edge of the dash close to the windshield above the gauge cluster toward the driver. The crack continues to lengthen and my concern is this presents a safety hazard that increases as the crack gets longer. …”

   NHTSA complaint #10818288, filed 2016-01, 120,000 miles

   “I have done everything in my power, knowledge and experience to address the issue of my cracked dashboard/pad. I have reached out to dozens upon dozens of other Tahoe/yukon owners who have experienced the exact same issue and have reached out to GM for further assistance to only have been turned away.”

   Latches, locks and linkages

   Door locks and actuators quit locking or unlocking

   • 53 complaints (10%)
   • median 37,431 mi at 3.4 yrs old (48 state mileage)
   • owner-quoted repair $400 (median of 12 quotes)
   • filed 2010–2015

   Complaints describe power door locks that stop locking or unlocking one door at a time, with the key fob and interior switches also failing to operate them. Owners report having to unlock the driver door with the key and open the rest manually, and some note the problem is worse in hot weather. Several say the dealer replaced lock actuators or latch assemblies, sometimes under warranty and sometimes at owner cost, and a few describe door handles that came loose or broke. Most often reported between about 25,000 and 60,000 miles, with some complaints up to roughly 100,000 miles.

   What to check: Cycle every door through lock and unlock using both the fob and the interior switches, and try each handle from inside and outside. Ask whether any lock actuator or latch has already been replaced.

   “A few months ago, the drivers side door wouldn't unlock. If manually pulled up, wouldn't lock. Chevrolet fixed the problem. Now, a few months later, my other 3 doors are all the sudden not unlocking. If manually pulled up will not lock. Chevrolet says its the actuators(?) door locks. I have to wait a few days until they can squeeze the truck in to replace all three...”

   NHTSA complaint #10349090, filed 2010-08, 35,890 miles

   “The door locks have gone out on my 2008 Tahoe approximately 6 months ago. Our children cannot open the doors to get in our out of the vehicle. The only door that will currently work is the driver door, which only works with the key. The Tahoe has a factor installed alarm system / key fob system, and does not control the doors to lock or unlock. You have to use the key to unlock the driver door, then manually open the passenger and rear doors from the inside, as well as manually lock them from the driver side.”

   Air bags

   Airbag warning light and open airbag recalls

   • 224 complaints (42%)
   • median 90,000 mi at 8.8 yrs old (63 state mileage)
   • 6 mention a crash, fire or injury
   • owner-quoted repair $822 (median of 5 quotes)
   • filed 2008–2025

   Owners report the airbag warning light coming on or flashing intermittently, and several complaints center on passenger-side inflator recalls for which they say parts or scheduling were not available for a long period. A few complaints describe airbags failing to deploy in a collision or side curtain airbags deploying without an impact. Some owners also tie their concern to the cracked dash around the airbag cover. Reported across a wide mileage range, from under 40,000 to over 200,000 miles.

   Recall 21V050000Recall 21V052000

   What to check: Check the airbag warning light on start-up and ask for a dealer printout showing whether the passenger inflator recalls have been completed on this vehicle.

   “Takata recall. This recall is taking too long and GM needs to find a remedy asap. I the airbag light comes on from time to time while I am driving my Tahoe and I am worried that it may be faulty and if I were to be involved in a accident it will not work or worse cause serious injury or death to me, the driver, as the lawsuit states that it may.”

   NHTSA complaint #11043293, filed 2017-11, 135,000 miles

   “Takata recall. My airbag has not been replaced by GM. My dashboard is cracked all around the passenger side airbag container. My car repeatedly notifies me that my airbag needs servicing. Gm needs to replace it. I go onto GM and get the attached message. Gm needs to replace with some replacement airbag soon.”

   Complaints describe random loss of power, dash lights flickering, a clock that resets, wipers running on their own, and the vehicle failing to start even though the battery tests good. Some owners report the blower, radio and window controls cutting in and out together, and one says the dealer replaced a wiring harness and the negative battery cable after repeated visits. The theft-deterrent system failing to deactivate is also mentioned. Reported mostly between about 60,000 and 120,000 miles.

   “While I was driving the air conditioner blower quit blowing and today when I went to a dealer for help he told me how to diagnose the fan relay, but it performed correctly. He also told me that he has seen before on the tahoes the A/C fan harness has melted before on this type of vehicle.”

   NHTSA complaint #10468991, filed 2012-08, 100,000 miles

   “There has been a recall on my airbags for years. For about 2 weeks now my service airbag message has been on. It came on when I started my car one day and has remained there. The 2nd issue is something electrical. I can be driving and I'll lose all power and lights/radio for 5-20 seconds and then pop back on. That has happened numerous times. Or I'll get out of my car and go to lock it and have no power. Both times that has happened , I popped the hood and the power came back on without me doing anything.”

   Engine

   Stalling, hesitation and transmission shudder around stops

   • 26 complaints (5%)
   • median 84,341 mi at 7.8 yrs old (20 state mileage)
   • filed 2008–2025

   Owners describe the vehicle hesitating or losing power when pulling away from a stop, and some report a sudden forward lurch while braking at low speed. Others mention a reduced engine power message with loss of throttle response, or the engine cutting out at a light and not regaining speed. Several say diagnosis was difficult, with dealers unable to duplicate the condition or repairs that did not resolve it. Mostly reported between about 24,000 and 180,000 miles, often in stop-and-go driving.

   What to check: Test drive from several full stops and at light throttle at low speed, and ask whether the transmission or torque converter has been serviced or rebuilt.

   “After coming to a complete stop I press on the accelerator, at times I press harder and harder before the auto starts to move and it then goes much to fast. This does not happen at every stop. It is either in the accelerator or the transmission. The dealer ship can not make it duplicate the situation because it does not happen all of the time.”

   NHTSA complaint #10293924, filed 2009-11, 24,113 miles

   “Torque converter went out completely causing me to have to replace the entire transmission, drive very low miles and do not pull/tow anything. Our dodge & ford both have well over 260,000 miles on them and have never had an issue. Cheap part were used in this Tahoe causing major repair failures and costs to repair”

Buying note. Check the dashboard carefully and confirm the open airbag recalls have been completed on the specific vehicle before buying, since those two account for a large share of owner complaints. A slow-speed test drive and a check of every door lock will also surface the other commonly reported problems.
