Vehicle completely shut off while crossing over a four lane highway to enter a shopping center. Safety could have been highly at risk to both passenger, on coming traffic side, and driver. Luckily the cars coming were far enough back that they were able to stop. I took my vehicle to the dealership where I bought the car brand new in 2018. They test drove the vehicle while hooked to a computer but could not find a problem. They tightened all connections to battery and other components and did updates to the computer on the vehicle. There was no warnings whatsoever that the vehicle was about to completely shut off. Previous to this incident I had been driving on 95S from Warrenton Vs to Clayton NC. I don't even like to think of what would have happened on 95 if my vehicle would have completely shut down. I am sure I probably would not be writing this report. Looking on the web this has happened to others with this same year and model of Cadillac.

While driving my Cadillac XT5 on the busy highway during the early afternoon, without warning the sunroof glass made a loud pop sound immediately followed by shattered glass. Glass fell all over the driver-??s head and body impairing my vision and causing me to make sudden stop on the shoulder of the highway. There is problem with the sunroof breaking and shattering glass while driving. Insurance claim filed and private auto glass dealer made repairs in excess of $1300. Shards of glass still remain in the sunroof screen closure until taken to auto detailed for removal at an additional cost to me, the registered owner. I dive in fear that this may occur again without warning which could pose extreme danger or accident.

I have had the vehicle, which is still under factory warranty, for 5 months. The vehicle began alarming on the first day I drove it (10/16/20). Monday, 10/19/20, the vehicle went into "park" while I was driving it. The dealership did a quick assessment and called back and told me the battery was the cause of the issue. My immediate questions were "why didn't the battery indicator appear"" and "why would a low battery cause the SUV to go into park while I was driving it"" however, as they were returning the SUV to me, the transmission light came on. The transmission electric control was replaced due to "an internal failure in shifter" that was undetectable. On 12/21/20, the same dealership replaced the water oulet because they found a leak "coming from between the thermostat housing and water outlet pipe". on 3/14/20, after driving the vehicle 175 miles at 75mph, the vehicle suddenly decelerated. The vehicle was not responding to me pressing on the gas pedal. No warning lights showed and no alarms sounded. Additionally, once the vehicle was stopped, it would not restart. Onstar ran a diagnostic report and no codes were found. The thermostat had a normal reading. The onstar representative recommended that I allow the vehicle time to cool and then restart the vehicle. I drove back home while making frequent stops to allow the vehicle time to cool off. On 3/15/20, I returned the vehicle to the dealership. On 3/22/20, the dealership notified me that they could not replicate the problem and did not find any problems during their diagnostic evaluation. They also did not test the vehicle by driving it either. I was told me to come pick up the vehicle without knowing the reason that the SUV cut off while driving it on the highway. The 2017 Cadillac XT5 is unsafe and could result in an accident or death. Please investigate this vehicle.

We were driving on the highway and suddenly we heard a loud explosion noise that resemble gunshot followed by highway noise. The car has a panoramic sunroof that was closed at that time however we can hear shreds of glass above the closed cover. I slowed down on the highway and we got out at the first exit. We pulled over on the side and called 911. There was no sign that any object hit the car; the panoramic sunroof exploded spontaneously.

A clear fluid was leaking from rear of car when parked in garage. Took car to dealer for service. I received numerous messages the part was on back order, had not been shipped from china, has been shiiped from china, in Michigan, had not shipped from Michigan, etc. During week four I went to dealer to get more details about lengthy process. I was told the car is legally a lemon after passing the 30 day point and to contact GM to begin the buy back process. I contacted GM nine times attempting to speak to a human. The 10th attempt lead me to "christina". I was advised to file the lemon law complaint through Nevada due to varying state by state laws, I went to dealer again last Monday & spoke to service manager. He told us part is in tx & delay was due to computer problems at factory. Options include buy back or repair. July 2, 2019 begins week seven my car has been at dealership. Also, there's been a knocking sound coming from the left side when making a hard turn (into a parking space.) took to service dept. They said they could not find anyting mechanically wrong & had "other customers' cars" requiring servicing. Took the car in again a week later. A mechanic and I drove car out of parking lot making left turn knock knock sound happens. Another left turin into parking lot and knock knock again taking all of two minutes. He knows what the sound is and will put repair order in to fix car. When I took car in 5/21/19 I advised them the knocking sound had returned and was coming from the right side now when a hard turn is made.

The "cue" system has malfunctioned. I have no navigation or radio and am unable to see how the controls are set for climate control. Also, the 360 degree cameras fail intermittently including the backup camera leaving me blind when parking or backing up. I have taken this vehicle to the dealership five times and Cadillac has now declared my vehicle a "lemon" and is repurchasing it. Interestingly, I've been driving to Cadillac dealerships throughout central Florida and have noticed a high number of XT5's with their dashboards completely disassembled in their service area. One service tech admitted he's also seen this issue in other XT5's. this sounds like it could be a pattern and Cadillac is denying to me that there is a problem.

The panoramic roof on our Cadillac XT5 can not be used without extreme pressure in the cabin when driving if you open the sun shade and open a window the same thing occurs, extreme pressure in the cabin, or open the sun roof when driving. The pressure is so extreme that it causes very painful pressure in the ears, to the point I almost wrecked the vehicle. The dealership and GMC are completely aware of this issue, but they said nothing when we test drove it, there is nothing stated about it in the owner's manual and nothing stated how to remedy this painful issue. After the first experience in Oct. 2017 shortly after leasing the vehicle, we asked the dealership about it, and the salesperson and his manager both knew about the problem and said it was an issue with all Cadillac models because they sealed the cabin so well. This is a significant safety issue because of what it causes to the inner ear and the fact that GMC never made mention of this issue so consumers can make an educated decision if they wish to have a panoramic roof. In our case, if we were told as we should have been, we would never have leased this vehicle. GMC must make buyers/consumers aware and the dealerships too, or not offer such sun roofs. I have reported this once, ref. # 11071918 and have no reply or answer.

My wife and I went for a ride with our little dog with us, and as always he likes the window down so he can stick his head outside. No sooner than we had lowered the one (1) window we noticed an extreme amount of cabin pressure and buffeting, to the point that it caused extreme inner ear pressure and pain. At this time we also had the shade cover for the panoramic roof opened. We closed the shade cover to see if that would help with the window down, but the cabin pressure remained. The only thing that seemed to help was lowering at least a second window in the rear. After this experience I called sewell Cadillac in houston, tx where we leased the vehicle and I talked to two (2) people about this problem which we had never experienced in any vehicle we owned prior to this. I was told that the dealership and Cadillac is aware of the problem and that the problem was created when Cadillac designed this and probably other vehicles and sealed the doors and the components to make for a quiet cabin experience, and not allowing any air to escape. The problem I stated is we were never made aware of this by Cadillac in any literature we had nor did anyone at the dealership make us aware prior to leasing. As I told sewell Cadillac representatives I talked to, we never experienced this with any past vehicle and if we had known and had been told about this issue, we would never had leased this vehicle. I did explain that now we can't ever lower a single window without the pressure and extreme pain and do not like to have additional windows down. We believe we were misled by not informing us of a known issue so as a consumer we could make a decision if it is something we could live with, and in our case we can't. we also believe since they were aware and never told us about this issue, this may be considered consumer fraud.

2017 Cadillac XT5. Consumer writes in regards to electrical issues with vehicle. Updated 10/04/2017

- Collinsville, TX, USA

Platinum version (top of the line model) has widespread premium leather dashboard defects on brand new vehicles, so bad that both showroom new replacement premium leather dashboards are all defective. I first noticed mine several days after purchasing mine in October 2016. It has taken over 9 months with GM/Cadillac corporate involvement to finally find my 5th replacement dash that does not have defective leather! the dealership showed me a brand new XT5 platinum on their showroom floor with bubbled premium leather dash. It is only affecting the XT5 platinum models because the leather is different. It is apparently a national issue.

I have an Cadillac xt 5 2017. The lane departure warning does not work as advertised. I have spoke with several people from the dealer to dealers representative and regional manager. After 5 weeks the regional manager told me that the ldw was working properly as designed. He offered me some type of compensation ( $300 ). he agreed that I was correct that the way Cadillac advertised this was incorrect and thank me for finding it. He said Cadillac will be changing how they advertise this option. Well great what do I do with a $ 54,000 dollar I purchase that had false advertising. I have had ldw in other GM vehicles and know how they work. Now to the problem, when I go over the line the seat is suppose to vibrate or hear a beep. I have tried to have either work but going over the line over 100 times it only worked 5 times. I was going over 40 miles per hour and the law was green but only alerted me those 5 times. Also I was about 6 feet over the line each tine it went off those few times. My concern is what happens if I nod off or fall asleep and drift over the line and I hit the car, curb, tree or telephone pole. I was also told that since I have lane keep assist that will keep my vehicle from going over the line. Well I also tried that and the car does slightly pull me back in but if I pull to the right or left on over ride the lka where is my warning. I can not be the only one who noticed this. Please help

The radio in the car keeps dropping sxm signal while driving down the street or highway or entering parking lots at nearby supermarkets or our lowes store. I have written Cadillac and am waiting for their response. While not a safety issue per SE, it is frustrating and not expected on a car that cost almost $64,000.
