- 2 mention a crash, fire or injury
- filed 2006–2022
Owners describe sliding doors that open, close, or reopen without warning, including while the vehicle is moving, and doors that will not fully latch. Some describe a remote button unlocking the doors and opening a sliding door, and a few report injuries or bruising when a door closed or stayed open unexpectedly. According to complaints, dealers sometimes replaced sensors, remotes, or door parts, or aligned the doors, and some owners say the problem came back afterward. Where mileage is stated, most of these complaints are below about 40,000 miles, with a few at about 136,000 to 140,000 miles, and some describe a door opening while the vehicle is moving.
What to check: Open and close both sliding doors from inside, outside, and with the remote, and check that each latches fully and stays shut. Ask the seller for dealer records of any door sensor, latch, or alignment work.
2 excerpts from owner complaints in NHTSA records
“It is probably a shorter list to list what we haven't had trouble with , but here goes. 1. The back power sliding doors will open and shut at will. Driving down the road, parted in the grocery store parking lot, etc. The neighborhood kids regularly come over to tell me my doors are open. My husband almost missed a flight because he spent to much time trying to fight with the door to stay shut. …”

“The engine stops without warning have had to go to GM dealer and get code to start it next three times I just wait in traffic till it started now I am scared to drive it think this car needs to be recalled and fixed before it kills me or someone else, I paid the GM dealer to look at it and they couldn't tell me what is wrong with it but agreed it did the same thing to them.”
NHTSA complaint #10639154, filed 2014-09, 60,000 miles“Vehicle would not restart and left me and my family stranded 1.5 hours from home and was towed by dealer. Once I got it back there were several other problems that I had faced before that were now occurring again. The sliding doors malfunctioned about every other day. The vehicle has given us trouble starting on two other occasions ,as well. These were not reported as we assumed that being a brand new vehicle that we must have left a light or something on. We knew that the problemwas with the vehicle and not our negligence.”
NHTSA complaint #10191524, filed 2007-05, 13,900 miles - Brakes
Brakes locking, pedal failing, or braking without warning
- 10 complaints (19%)
- median 57,947 mi at 4.4 yrs old (10 state mileage)
- filed 2007–2016
Owners describe brakes that lock suddenly, sometimes for a few seconds, and in some complaints the vehicle veers as a result. Other complaints describe a brake pedal that resists and then goes to the floor, brakes that apply without warning, and a parking brake that does not release. According to complaints, dealers were sometimes unable to duplicate the failure, and an owner was told a pedal delay was linked to software. Where mileage is stated, these complaints fall between about 25,000 and 113,000 miles, and some occurred at low speed, around 10 mph.
What to check: On a test drive, check the brake pedal feel and that the ABS, stability, and parking brake warning lights go off, and ask for records of brake or stability repairs.
2 excerpts from owner complaints in NHTSA records
“I bought this vehicle in feb. 2015. About a week after purchase I was going to work one night and the vehicle suddenly veered to the left and brakes locked. The stability light then came on. I pulled over and shut the van off and restarted it . No light was on then. About one month later it did it again. This time I was going about 50 miles ph. A car behind me almost hit me from behind due to the sudden stop.another month went by before it started doing it again. This time it veered into the path of a semi tractor trailer. …”

NHTSA complaint #10217539, filed 2008-02, 25,000 miles - Suspension
Suspension clunks, noises, and worn joints or bushings
- 7 complaints (13%)
- median 91,330 mi at 6.7 yrs old (6 state mileage, few)
- 1 mention a crash, fire or injury
- filed 2009–2021
Owners describe clunking, cracking, and loud noises from underneath the vehicle, including front wheel bearing noise. Complaints tie some of these to worn trailing arm bushings and a knuckle, a ball joint that pulled loose, or a control arm that needed replacement. Some owners say the vehicle was not covered by recall 10V110000, and a complaint describes early rear brake wear linked to the trailing arm failure. Where mileage is stated, these complaints fall between about 42,000 and 161,000 miles, and some do not state mileage.
What to check: Ask whether the VIN is covered by recall 10V110000, and have a mechanic check the rear trailing arm bushings and joints for play or wear on a lift.

“The veh has a niose in the rearafter start up, sometimes it go away after driving for a while but it come back over and over again, I took it to the dealership they suggested I replace the controlled arm right and left and replace the steering sensor along with the thermostat and this will fix the problem the cost will be 1,500.00. Is this a recall problem.”
NHTSA complaint #10823641, filed 2016-02, 161,300 miles“Before 46,000 miles both front wheel bearings on my van went bad they went bad within 5 months and 3,000 miles of each other.

- 6 complaints (11%)
- median 42,500 mi at 5.4 yrs old (6 state mileage, few)
- 2 mention a crash, fire or injury
- filed 2008–2022
Complaints describe steering that suddenly becomes hard to turn or control, with some drivers losing control and crashing.

An independent mechanic reportedly found the rack and pinion needed replacement. Where mileage is stated, these complaints range from about 3,000 to 82,000 miles, and some describe difficulty at low speeds.
What to check: On a test drive, check for hard or vibrating steering at low speed, and ask for any rack and pinion or steering repair records.
2 excerpts from owner complaints in NHTSA records
“On may 2, 2013, about 10am, I was on my way home. The steering wheel suddenly out of control and my car hit on a car park on the street side with none inside. My car had severe damage and cost about $10,000.00 to fix. The other car I hit on had medium damage. The air bag pop out with a lot of dust and it was flat. A lot dust blow on my face. The air bag had no air at all. It was all flat. The steering wheel had been kind of tight and difficult to turn for three years. …”
NHTSA complaint #10533050, filed 2013-08, 45,000 miles“The power steering rack failed, making it difficult to control/steer the vehicle at low speeds. I have since heard this referred to as GM power steering syndrome. It is a common problem of GM cars where the valve in the power steering rack has problems. The power steering fluid cannot get through, particularly at low speeds, making it very difficult to steer. (at higher speeds - when the accelerator is depressed - there is extra pressure forcing the fluid through, so it is a bit easier to steer at higher speeds. …”
NHTSA complaint #10406391, filed 2011-06, 82,016 miles
Buying note. Ask for records of door, no-start, and brake repairs, and check the VIN against recall 10V110000 for the rear suspension. Test the sliding doors, brake pedal feel, and steering on a test drive, since these themes recur in the complaints above.

Example complaints
Brakes: “My vehicle is equipped with anti lock brakes. The same system is used for traction control and stability control. My vehicle is prone to brake sensor failures. Whenever one of the sensors fails the onboard diagnostic system disables all 3 of these safety features. I currently have the third sensor failure since I have owned the vehicle.”
NHTSA complaint #10274026, filed 2009-06, 42,000 milesElectronic stability control: “The check engine light has been illuminated as well as the traction control light is on (indicates ABS needs to be serviced) also transmission slips when moving forward. At times when both the engine light and ABS light are on the engine will reduce power. Transmission was replaced at 63,000 for the same thing! Have had to numerous shops who cannot locate issue. The doors will not lock shut- they come forward and pop out and reopen. Must operate manually.”
NHTSA complaint #10558997, filed 2014-01, 136,000 milesElectrical system: “When doors are locked, either sliding door button on remote will unlock all doors and open sliding door with driver not knowing it leaving interior exposed to weather, thieves, animals and anything else nearby. Gm refuses to correct it or even consider a buy back.”
NHTSA complaint #10147676, filed 2006-01, 4,600 milesBody and structure: “The automatic sliding doors won't close. It opens up again when the closing slide door touches the frame. This happens every a few days!! Very frustrating. And I saw there are 4 or 5 similar compliant reports on this already. So looks like it does happens on a number of vehicles already, not an isolated incident.”
