Owner reports
Selected complaints filed with NHTSA by 2015 Chevrolet Suburban owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns 2015 Chevrolet Suburban. The contact stated that while inspecting the vehicle, the contact saw rust on the frame and saw horizontal lines that became progressively worse over time. A dealer was contacted. The vehicle was taken to the dealer, and the contact was informed that wax could be added to the rust spot and that the repair would be out-of-pocket because the failure was not under warranty. The vehicle was not repaired. The contact related the failure to Technical Service Bulletin: 19-NA-255 (Wax Coating on Frame Peeling, Metal Shows Corrosion/Rusting); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 114,481.
The contact owns a 2015 Chevrolet Suburban. The contact stated that the rear liftgate failed to close. The fire department removed the hydraulic shock to close the rear liftgate. The dealer was made aware of the failure but provided no assistance. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 78,000.
The vehicle has an unusual vibration at highway speeds. The roof bows have detached from the roofing sheet metal causing the sheet metal to vibrate. The vibration causes the headliner to detach, and associated components (heat/ac vents and lights) to fall on occupants. The vibration causes significant air pressure issues which create dizzying effects and headache. In this case, the dealer has re-attached the roof bows twice and now they are detached again, but the vehicle is out of warranty. This is a common problem with these vehicles and can be found in multiple locations online, however GM is refusing to fix this problem.

Tl* the contact owns a 2015 Chevrolet Suburban. While attempting to brake the vehicle, the brakes made an abnormal loud noise. The vehicle was taken to the dealer where it was diagnosed that the brakes and rotors needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that the brakes and rotors had been replaced a total of three times since the purchase of the vehicle. Also, while attempting to accelerate, the vehicle hesitated and slowed down. The vehicle was taken to the dealer. The contact was informed that the vehicle had not failed and that was how it was calibrated. The contact also stated that the liftgate failed to open automatically and had to be manually operated. The vehicle was taken to the dealer, but the failure could not be duplicated. The manufacturer was made aware of the failures. The failure mileage was 43,000.
All of the window pillars have broken and/or come loose, dues to a manufacturing problem with the clips used. The roof rack rail also flies up while your driving and smacks the roof because of the faulty clips. I also noticed a water leak on the headliner (see attached picture) after it had rained one day. My Suburban was parked outside and I noticed the leak when I got into the car. My seat belts were also wet from the leak. This seems to be a common occurrence and issue with other 2015 Suburban owners and is a safety hazard, especially if the wiring sits in the water. I had taken it in to a Chevy dealer to get it checked out, but I will have to pay to replace everything needed. If these issues are manufacturing errors and such a common occurrence, why should I have to pay to fix them? And more importantly, why is there no recall on them?
Was driving at highway speed and heard a pop from behind driver. Started hearing a flapping sound and found the drivers pillar cover had come loose at the top. Would not snap back so secured with duct tape as so not to lose the part. Later the same day found 2 other were loose so secured them so as not to have them come off. Have researched this and found many others have had the same problem. Many have said that if under warranty they were fixed but only to have the problem occur again. Have 45,000 miles on vehicle when this occurred so not under warranty. Will confront the dealer just to see if they admit to no good fix and thinking this is just the owners problem. Hard to believe this happens on a $70,000 car.
The black trim on the passenger side door (covering the space between the front & rear doors) has come loose and the vibration is noticeable at highway speeds. This is not covered by the certified pre-owned warranty or the extended warranty I purchased separately from the dealer. The dealership has told me it's a $250 repair and have heard many complaints of this already from other owners. I've got one in need of repair now and another is coming loose on the other side. As the vehicle owner, I'm surprised the manufacturer is not taken care of this on a 2 yr old vehicle and I'm concerned at $250/trim this is going to be costly issue going forward if they don't address it.
Purchased a 2015 Suburban new from jim ellis Chevrolet. At about year 3 of ownership, just after warranty expiration, I noticed moisture in drivers side headlight assembly. About a year later the blinker stopped working. The only way to repair it is to install an entire new assembly. The part is $1,200 alone. The is not a warranty issue, but a defect that Chevy will not address or admit. It is also a major safety issue. Additionally, the paint on the hood and roof started failing at about year 4. Again, another defect. Chevrolet will not address either of them. One is a safety issue, the other cosmetic. Very frustrated.
When traveling at interstate highway speeds vehicle had shaking, shimmying, vibration and buffeting as well as loud hum and wind noise causing nausea resulting in nausea and dizziness to the driver. This was worse on new macadam and on grooved highway but occurred intermittently on other surfaces, I just purchased this vehicle used and it is certified. I was unaware that this is a common issue and understand now that there is no recall to fix this and that GM has not found a permanent solution to the problem. The vehicle was also exhausting to drive on the highway because of the aforementioned issues.
Tl* the contact owns a 2015 Chevrolet Suburban. The contact noticed water leaking down from the roof inside the vehicle each time the vehicle went through a car wash or when it rained. The vehicle was taken to conklin Chevrolet salina (2700 s 9th st, salina, ks 67401, [phone]) where the contact was informed that the entire roof needed to be removed to find the origin of the leak. The vehicle was not diagnosed or repaired due to the repair fees. The manufacturer was notified of the failure and provided case number: 9-5410228962. The approximate failure mileage was 85,000.
