2011 Chevrolet Suburban Problems

What owners report

Owners of this model year most often report a cracked dashboard, with fractures appearing above the instrument cluster and around the passenger airbag area and sometimes spreading quickly; many say the cracks began without any impact or rough-road event. A second large group of complaints concerns the front passenger airbag inflator recall and the long wait for parts, and a smaller set covers fuel tank swelling with a fuel odor, stalling or electrical dropouts while driving, and occasional brake problems.

1. 1
   Body and structure

   Cracked dashboard at airbag and instrument cluster

   • 63 complaints (43%)
   • median 65,000 mi at 5.1 yrs old (47 state mileage)
   • filed 2013–2022

   Complaints describe cracks appearing in the top of the dashboard, most often over the instrument cluster on the driver side and along the seam above the passenger airbag, and then lengthening and spreading. Owners say the cracks developed while the vehicle was parked or on smooth roads, and some report rattling afterward. According to the complaints, dealers generally quoted a full dashboard replacement at the owner's expense, and several owners say the repair was not covered by warranty. Reported from about 1,000 to 105,000 miles, with many appearing in the 35,000-75,000 mile range and in vehicles a few years old.

   What to check: Inspect the top of the dashboard above the gauges and along the passenger airbag seam for hairline cracks, and press lightly to feel for flexing or loose trim. Ask whether the dashboard has ever been replaced.

   “I was driving on a nicely paved road (no bombs, potholes, etc...) when all of a sudden my dashboard cracked! It is now rattling and jiggling and causes a distraction to my line of sight as I'm driving. I went to my dealership and was told that it is not covered under my warranty and I will have to pay the whole amount out of pocket to have it repaired.”

   NHTSA complaint #10907969, filed 2016-09, 99,000 miles

   “A small crack began on the driver side of dash board. Within weeks, the crack became much bigger. After two more weeks, I noticed another crack on the passenger side of the dash. Soon, it became much larger too. Now, there are several cracks on the dashboard. This automobile was not involved in any type of accident or driving on rough terrain. I don not understand why the dashboard would crack. I have never owned a vehicle which has had this happen.”

   Air bags

   Passenger airbag inflator recall, parts not available

   • 38 complaints (26%)
   • median 78,144 mi at 5.5 yrs old (10 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2015–2022

   Many complaints are about the front passenger airbag inflator recall rather than a new failure: owners say they received a notice but were never told when parts would be ready, and dealers told them the remedy could not be performed. Some owners in hot, humid climates describe added concern about inflator performance, and a few report the airbag warning light coming on. A separate complaint describes the passenger dash airbag not deploying in a collision while other airbags did. Reported across a wide mileage range, roughly 35,000 to 151,000 miles, often years after the recall notice was received.

   Recall 21V050000Recall 21V054000

   What to check: Ask for written confirmation that the passenger airbag inflator recall has been completed on this vehicle, and check that the airbag warning light does not stay on after startup.

   “This is a florida vehicle where heat and humidity (the major factors identified with failures of these airbags/inflators) can cause my Suburban to be a high risk to me and my family. We submitted for this recall in 2016 and have yet to be contacted on status or estimated time for the parts/procedures to be ready to complete this repair. As GM disagrees with this recall, they appear to be stalling in hopes that the vehicles will just be retired before they have to repair them. …”

   NHTSA complaint #11384623, filed 2020-12, 106,056 miles

   “Takata recall _ my airbags have been recalled but no one has contacted me to fix them and the dealership said they can't fix them with out the parts. I need help.”

   Electrical system

   Electrical dropouts, stalling and warning lights

   • 15 complaints (10%)
   • median 90,000 mi at 6.9 yrs old (11 state mileage)
   • filed 2014–2026

   Complaints describe the electrical system cutting out at speed: the tachometer drops, instrument panel lights come on, door locks cycle and the radio turns on and off, and the vehicle has to be restarted after a short wait. Others report the service traction control and ABS lights staying on and interior lights flickering, and one owner describes the engine shutting down with the cruise engaged and poor response below a quarter tank. Several say dealers could not reproduce or diagnose the problem. Reported from about 48,000 up to nearly 150,000 miles, often during highway driving.

   Recall 14V827000

   What to check: Check that all warning lights go out after starting and test the ignition key for binding or sticking in the start position. Ask whether any intermittent no-start or electrical faults have been diagnosed.

   “On my vehicle brake oil was leaking my mechanic find that master cylinder leak. After changing the master cylinder when I start driving my brakes got locked. I park the car when it's cool down brake released but same thing happened when I start driving . So my mechanic changed the brake booster but now strange thing happening that brake pedal goes all the way down to floor and it's barely brakes. Just left the SUV on a chevorellet dealer ship see what they will say. …”

   NHTSA complaint #11233577, filed 2019-07, 280,000 miles

   “While driving on the highway I was using the cruise control and the car began to increase in speed without my control. It went from 65 to 90 in a few seconds and I had to slam on the breaks to get it to stop. This has happened several times. Also we can never let the gas get lower then a quarter of a tank or the car just shuts down like its empty. Sometimes the engine will just rev up for no reason and other times it doesn't accelerate properly. You can push the gas and it feels like the speed is delayed but then will catch up.”

   Fuel system

   Fuel odor, swollen fuel tank and fuel leaks

   Mentioned in 4 of 60 sampled complaints

   Owners describe a fuel smell and a clanking or abnormal noise from underneath while driving, with the fuel tank visibly swollen or expanded; in one case the tank was said to rest against the driveshaft. Complaints also mention the fuel level sensor failing and the tank developing a leak after repeated smoke and pressure testing, and owners report the cause was hard to pin down, with parts like the purge valve, canister and fuel sensor replaced without lasting success. Mostly described at higher mileage, from about 140,000 to 191,000 miles.

   What to check: Look underneath at the fuel tank for bulging or wet spots, and note any fuel smell after driving or when the tank is full. Ask whether the fuel level sensor or purge valve has been replaced.

   “Engine light on-diagnosis p0455. Last 2yrs took to many repair shops. Replaced, gas cap, purge valve, canister valve, charcoal canister. Took to chevy. They replaced purge valve because they said other mechanics used non chevy parts. Engine light came back on. Chevy did smoke test and swore it was the fuel sensor cost $1200+. Engine light back on after a week. Another smoke test and now pressure test blew a small section of fuel tank where it now leaks. Chevy said the seal most likely not seated properly and I need a new fuel tank about $1000. …”

   Brakes

   Brake pedal low, brake lines collapsed

   Mentioned in 4 of 60 sampled complaints

   Complaints describe the brake pedal going to the floor or the brakes failing to slow the vehicle, with the traction control light coming on in one case; a dealer reportedly found that the front and rear brake lines had collapsed and needed replacement. Another owner describes a leaking master cylinder followed by brakes that locked and then a low, weak pedal after the booster was replaced. Described between roughly 70,000 and 280,000 miles.

   What to check: Test the brake pedal for firmness and travel before and after a test drive, and look for fluid seepage around the master cylinder and along the lines. Ask about brake line or master cylinder service history.

   “We were on a two lane road heading westbound. East bound vehicle crossed center strip striking our front drivers side of vehicle. We were on a curve in the road, traveling approx 40-45mph while other vehicle was traveling the same MPH if not more. Our vehicle sustained frame damage to the front drivers side as well as all airbags deploying except passenger side airbag/in seat airbag. …”

   NHTSA complaint #11025280, filed 2017-09, 92,376 miles

   “I have noticed that when decelerating & applying my brakes when approaching a stop that my vehicle actually will accelerate all of the sudden. This has happened on several occasions, not always, but enough for me to be concerned. My daughter also experienced this sudden acceleration when she was driving my Suburban. She, like me, said it happened when she was approaching a stop sign and was applying brake pressure. This should be investigated.”

   NHTSA complaint #10512842, filed 2013-05, 40,000 miles

Buying note. Check the dashboard closely for cracks and confirm in writing that the passenger airbag inflator recall has been completed, since those two account for most complaints on this model year. A test drive that includes highway speed and braking is worthwhile to look for electrical dropouts, warning lights and a soft brake pedal.
