Body problems of the 2015 Chevrolet Suburban

Rear lift gate will not latch. The lift gate can open during vehicle movement.

Blind spot detection modules are bad, vehicle will not detect object in blind spots.

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 driving on the highway, the door locks will unlock by themselves. Sometimes all of the doors unlock, sometimes just one or two doors. We have heard the sound of unlocking doors several times in the past as we drove. On August 22, we heard the unlocking sound, and then observed the doors unlocking. After relocking the doors, the incident happened several more times. This can be very dangerous!.

Vehicle has 49,000 and is garaged and I have had to have the hood, roof and complete drivers side repainted due to clear coat/paint failure. Have spent at least $2500 out of pocket.

Tl the contact owns a 2015 Chevrolet Suburban. The contact stated that water was entering the vehicle through the antenna. There were no warning indicators illuminated. The vehicle was taken to bennett Chevrolet (6721 black horse pike, egg harbor township, NJ 08234, (609) 641-0444) where it was diagnosed that the antenna needed to be replaced. The vehicle was repaired. The manufacturer referred the contact to NHTSA. No further assistance was provided. The failure mileage was 50,000.

Roof mounted "shark fin " antenna leaks and resulted in short circuit of the electrical controls disabling the Suburban. Second time in 2. 5yrs the antenna had to be replaced.

Badly faded paint top of hood and roof top. Magnetic shocks had to be replaced at cost of $1800.

While driving above 70 mph, the vehicle begins to have vibrations. Have taken our Suburban in for multiple repairs but their reasoning was the vehicle and tires were not balanced however after replacing the tires and getting a road forced balance it did not resolve the issue. It does not feel safe to drive above 70mph.

Front drive applique came loose from the car, while driving on a highway. The adhesive wore out and created an issue with expanded blind spot and part potentially falling off the vehicle. I first taped it back and then glued it temporarily. When I took my vehicle in for service, the dealer noted that all panels were faulty and needed to be replace. I notified chevy about this issue, as it appears to be a manufacturing defect.

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?.

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.

2015 Suburban when is raining I have water coming fron the roof on the driver side is coming fron the shark antenna is to much water and my on star is no working and the gps is not working and the dealer say to me no warranty is not fair.

The paint (black) on the roof cracked and turned white like spider webbing. Chevrolet pointed the roof I had to part 65 % and they paid the rest. Now the same thing is happening on the hood. I was told its because of the sun and heat. I don't believe so, because the rest if the vehicle sits in the sun daily and the paint is fine. The vehicle is garage kept at night. I have a 2013 f-150 that sits in the sun all day and in not garage kept and the paint is still like new. There has to be something wrong with the paint or prep job was not done properly.

Antenna I have water from the antenna on the top.

While shopping for a used 2015 Suburban I noticed that all of them had a fair amount of rust on the undercarriage. The one I ended up purchasing had rust as well but had the least of the ones I looked at.

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.

In March of 2017, I noticed that the paint on the hood and roof was starting to discolor very badly. I went to selman Chevrolet in orange CA where I purchased the vehicle new to show them. I was told that something must have gotten on the paint. I told them that was not the case since I clean cars myself. Car is now really getting worse. I believe that a car as new as mine and with the good care as it has received could only be due to defective paint.

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.

Contact owns a 2015 Chevrolet Suburban. The contact stated on all four doors exterior trim detached from the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed that the adhesive on the trim was inadequate and needed to be reapplied. The vehicle was repaired however the failure recurred. Heartland Chevrolet located 501 n state route 291, liberty, mo diagnosed that the bonding agent on the trims were defective and the panels would have to be replaced. The manufacturer was notified of the failure. The failure mileage was approximately 73,105. Kh.

Sail panels (pillar caps) came loose from their mounts. Internet search revealed that this is a problem with 2014 and newer Suburban type vehicles. Mounts can detach from the vehicle at high speed due to wind. They would be a traffic hazard to other vehicles, motorists or pedestrians.

I have a 2015 Suburban and the door trim between the doors comes loose. Our vehicle is out of warranty we took to the dealer and the service tech says they have having a lot of issues with this. We were just in a 2015 GMC denali and they are having the same thing going on.

The contact owns a 2015 Chevrolet Suburban. While driving various speeds, the exterior window panels failed on the front passenger and driver side doors. The vehicle was not diagnosed or repaired. The contact stated that this was the third time the failure occurred and the panels needed to be replaced. The first two times they were replaced under warranty; however, the manufacturer declined to repair the last failure. The manufacturer was made aware of the failure. The failure mileage was 25,000.

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. . Read more...

Roof will not remain attached to the roof bows. This causes buffeting similar to a window being down when all are up. The results span from annoying to painful. Also the vehicle exhibits loud booming noises over rough pavement that is not prevalent when the roof is secured. The dealer repaired and reattached the roof bows but the repair only lasted about 2 months and a 1000 miles. The dealer has stated they have done all that they can. If the vehicle was crash tested with the roof attached to the support bows then it seems that a roof that has detached could be less safe to unsafe since bow collapse and trajectory during a rollover will be altered. A further issue is that when the roof bow behind the sunroof detaches, the roof lifts and this can cause leaking. As can be seen in the pictures, one shows the forward sunroof to roof interface which is very uniform. The rear surface as lifted in the middle and will get higher with time. The third picture shows the arc in the roof.

The drivers front door vertical trim in coming off and catching in the wind. Creates a loud wind noise when going down the road. The piece will not snap back into place.

I purchased a brand new 2015 Chevrolet Suburban lt on December 20, 2014 and by December 23, 2014, there was a major water leak about the driver visor and headliner and equipment failures. I noticed that the gps, compass, onstar and mylink were no longer working. As of December 31, 2014, I still do not have my Suburban back and I have been told that part is not available in the us.

The contact owns a 2015 Chevrolet Suburban. The contact stated that the front spoiler was too low causing it to encounter the ground when driving. The vehicle was taken to a dealer, who adjusted the spoiler but the failure recurred due to the location the spoiler was re-positioned. The contact mentioned that the front spoiler continued to fracture especially when driving over an uneven pavement. The manufacturer was notified of the failure. The VIN was not available. The failure mileage was not available. Updated 6/18/cn.
