Lift gate is having trouble opening

- Vicksburg, MS, USA

While driving approximately 60 mph on a deserted flat stretch of road surrounded by farmland, my sunroof suddenly exploded. The screen was open to provide light but the glass was shut. No other cars were nearby nor were any hills where a rock could fly from. It was just sudden. It sounded like a loud explosion and suddenly glass was flying all over the car. Fortunately, I didn't crash the car. Myself and my son who was in the passenger seat, we were both covered in glass.

There is a water leak in the roof, on the driver side, right above the A-pillar. This has happened on multiple occasions during a heavy rain storm. The leak occurs regardless of whether or not the vehicle is in motion. After taking it to the dealership for service, I was informed there was a manufacturer defect which could cause some gapping in the vehicle body roof ditch driver side, which may allow water to leak through. I am concerned for my family's safety as this situation could create mold and mildew in the interior liner. Also, it could potentially lead to a very dangerous situation if the gaps/voids in the body become larger, allowing water to leak through at a greater velocity during high speeds or on the freeway. I was also informed that this is a very common issue on multiple vehicles from GM during the selected model year. Dealer attempted to service vehicle multiple times but there is still a water leak.

Vehicle vibrates during driving speeds above 35 mph. Had tired rotated and balanced, still vibrated, replaced tires and received 4 wheel alignment, still shakes bad. When traveling at speeds above 35, seats starts to shake as if you are traveling over a bad bumpy road. This occurs both on city streets and highways.

The exterior doors on the driver side made noise while in motion and we discovered the door jams had become loose or detached in spots. This is both driver side doors of a 4-door vehicle. We took it to the dealer and their invoice is quoted as follows "install left fr applique. Replaced the left front and left rear applique". the total cost was $164.23. I am furious this wasn't under warranty or a recall. This is a 2 year old $60,000 vehicle and I'm upset we had to pay to replace these parts. I have contacted GMC who noted and recommended I contact nhta, which is the purpose of this complaint. The dealer told us they have replace many of these and it's not a recall item, but it should be. Thus, please note and investigate this further for possible recall and reimbursement. Thank you.

The vehicle has leaked water in the seams of the back driver side since the initial purchase. It has been repaired nine times by two different dealerships and it still leaks. The vehicle now contains a high moisture reading and was tested by a mold specialist and determined to have mold. The vehicle is currently with the dealership.

Window appliqus on both sides of vehicle became loose and were flapping while driving. This was concurrent with a very noisy cabin, likened to the sound of a window being open while traveling at highway speeds. These appliques were previously replaced by dealer after incidentally being found loose. The noisy environment in cabin is very loud and distracting, causing driver and passengers to get headaches and causing driver to become distracted.

Our vehicle has a significant vibration in V4 mode when traveling between 45-65 mph and above. The vibration is also accompanied by increased cabin pressure. These issues are causing headaches, nausea, dizziness, and are further exacerbating my wife's multiple sclerosis. We also have a popping sound coming from the rear of the vehicle's suspension when turning that makes us feel unsafe. The vibration started right after we took delivery of the car and has only gotten worse. We bought the car in April 2015 and the issue continues unfixed to this day. The popping noise started about 3-4 weeks ago and it sounds like a suspension component. Our ac recirculating feature also does not work and it allows harmful exhaust smoke in.

All doors on the vehicle lock when transmission is put into gear and all doors lock several seconds after door is shut with engine off. The automatic door locks can not be deactivated by myself or by the dealer. I find this both a safety issue and a inconvenience. As a commercial truck driver driven millions of miles I have both witnessed and have directly been involved with trying to get people extracted from wrecks. Due to locked doors in several cases this has not been possible without breaking a side glass and physically unlocking the door from inside of the vehicle. In one accident two people were unconscious after a crash with the engine running and a fire under the hood, the doors were locked. In another, a person was having an epileptic seizure after a crash and again doors were locks. In the last example a man died after driving into a canal, rescuers were unable to break the glass in time to save the driver. I should have the ability to decide whether to have the doors automatically lock; not the manufacturer. The 2013 and older GMC trucks the automatic door locks can be deactivated but 2014 and newer GM refused to release the program to the dealers or public so I have no option but to drive with locked doors. I am asking to have GM release the program to achieve disabling the automatic door locks.
