When backing car up, often times the yellow "guide lines" appear, often times don't. Note makes no difference if daylight or night, weather car is clean or dirty (not affected by backup camera), clear out or raining. Brand new in April 2018, picked up from dealership, has happened since 1st week of operation. Took to dealership recently, could not find issue, said no known problems with like cars.

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.

After a hard rain or car wash, the door locks are rendered non functional by use of the fob , outside door handle lock button and automatically locking when put in drive. All doors will not lock / unlock with the engine "on" or "off". This has occurred multiple times and is repeatable. Condition clears up if car is left parked for 6+ hours. Similar complaint occurred before but w/o water. The issue was fixed by the dealer "reprogramming".

My 2017 Xt5 completely shutdown on my on Saturday, 10/7. I was at a stop light & when I pressed the accelerator, the instrument cluster had a number of lights come on & the vehicle was very hard to accelerate. I had to pull over immediately & then the car shut down. It was completely dead: the hazard lights did not work (very scary) & onstar and the sos button would not connect. After about 5-10 minutes, onstar was connected & I was told not to drive the vehicle due to engine & transmission codes. The vehicle was towed the dealer by roadside. On Monday, the dealer provided me with a loaner while the diagnosed the vehicle. On 10/11, when I went to pick-up the vehicle, I was told the issue was a 'logic lock,' the car was driven for 4 miles & considered fixed. I refused the car as we need to know the root cause. The dealer still has my car and has not contacted Cadillac yet. I am still waiting to hear from them and also have a case opened with Cadillac customer care, but they are less than helpful. The poor customer service is one issue, but the greater issue is the safety of my car and the fact that it completely died on me and the dealer thinks clearing some codes will resolve it. Please help. God forbid this happens to me or someone else again. It is completely unsafe.
