There is a water seal leak around the driver side headlight. I have photos showing proof of standing water. It has now caused the headlight, left turn signal, and drivers side brake light to fail. My passenger side headlight is doing the same. I have no headlights, no driverside lights period. I drive 2 children around in this car and it's gotten very dangerous. I contacted GM, and the local dealership and they won't fix it. I'm a [XXX] and don't have the $3200-$5000 I was told the repair would be. It is a problem in certain GM models, Cadillac Srx 2010-2015 having the same issue and the recall being fixed for those drivers. So, I have no choice but to drive around with no headlights, no left blinker, and no driver side brake light with two you children. I have to work and have no other options. It's a catastrophe waiting to happen, I live in the metropolitan area of Atlanta, Georgia. Please help me with this, I am terrified to drive this car around. I've had two people flag me down at a red light to let me know my brake light is out which is terribly dangerous and if it starts raining while I am out I have no headlights. This has become an emergency situation for me and my children. I have photo proof of the water pooling inside the headlight assembly. The seal is so bad that even covered the condensation pools inside the headlight. Please help me get a dealership to fix this issue. They want to charge me $275 for diagnostics and this is already and issue on this model car, reported by many drivers with the recall on the Cadillac. They need to fix it before I end up a casualty to this problem. Thank you so much. I can send a video of the emergency flasher and signal not working. I replaced the headlight in January and the new one never worked. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

[XXX] my car failed to let me use the brake, i was going about 45mph and when i went to apply brake pressure the pedal was so stiff i couldnt use the brake. Causing from end collision, when i made a trip to springdale to have my car inspected it didnt make it, started backfiring and dying around 65 mph then the motor blew, it had some issues starting but nothing like what happened within that few seconds. Im out of a car now because it drove perfect and i never have to give it thought. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The headlight area had condensation in it that resulted in water in the headlight. This caused the headlight to go dark. This is a safety issue as one of my headlights is not working. I can’t see that section of the road or adjacent sidelines. Very dangerous particularly at this time of year with deer running into road from the side. There are many other regal owners with this problem which can be verified by googling the problem. This is the second time the light has failed for condensation. Other drivers and pedestrians are at risk because they cannot be seen with the headlight out. Headlight was replaced once and has failed again. Cost to repair 2 years ago $1600 new estimate $1800. This is for one headlight but recommended to replace both.

Car lost all electrical power while driving (moving) and fully shut down, stalling immediately. Nothing electrical worked, including 4 way flashers. The alternator was just replaced 2 weeks after this same full loss of electrical power was diagnosed when going to start the car while parked. The battery was fully recharged at the repair shop and deemed ok. I had my road service come out to address the issue. Before they arrived, I was able to restart the car. The service tech checked the battery and alternator. Both checked ok, but the battery was almost drained and did not show signs of any dead cells, despite it having been able to restart the car shortly before the road service arrived. We replaced the battery. Car is in the shop now. The safety risk is full loss of power while moving resulting in no brake lights, 4 way emergency lights, full stall, loss of power steering and brakes that can lead to a collision on the highway. This type of problem has been reported on numerous Regals
