AIR BAGS

1 complaint

The airbag system failed to deploy during a single-vehicle accident in which the car left the service road and struck a tree. The vehicle sustained significant front-end damage. The driver lost consciousness or experienced disorientation and was unable to recall the events leading up to or immediately following the accident. The lack of airbag deployment increased the risk of serious injury, especially due to the vehicle impacting a tree and being lodged several feet off the road in the woods. Although there were no major injuries in this case, the airbag failure presented a serious safety risk and could have resulted in much worse outcomes. No, the airbag failure has not yet been confirmed or diagnosed by a dealership or independent service center. However, an insurance adjuster did state that based on the crash damage, the airbags should have deployed. The vehicle has not been inspected. No — there were no warning lights, messages, or symptoms indicating a problem with the airbag system prior to the crash. The vehicle appeared to be functioning normally before the incident.

To Whom It May Concern, I am writing to express my serious concerns regarding a known issue with the 2018 Cadillac CTS that poses a significant safety risk. The LCD/backup display screen in my 2018 Cadillac CTS has cracked on its own, taking up the entire display. This is a well-documented problem that many Cadillac owners have reported to GM, yet the manufacturer refuses to take responsibility or remedy the situation. The cracked display screen severely compromises the vehicle's safety features and functionality, including the backup camera and critical driver information. Driving with a completely shattered display is extremely dangerous and unacceptable. As the manufacturer, GM is fully aware of this defect but has failed to issue a recall or provide any solutions to affected customers. This is negligent and puts the safety of drivers and passengers at risk. I demand that GM take immediate action to address this issue, whether through a recall, extended warranty coverage, or full replacement of the faulty display screens. Leaving customers with such a critical safety hazard is unacceptable.

Rear differential failure confirmed by the dealer at 41,000 miles. Told not to drive it as rear wheels could lock up causing accident. Rear was making load noise 2 days prior to failure with fluid leak upon inspection. Dealer states failure is under warranty but no parts available for 3-6 months.

POWER TRAIN,ENGINE

1 complaint

I WAS DRIVING MY 2018 CADILLAC CTS BETWEEN 50-60MPH AND I LIGHTLY TAPPED ON THE GAS AND THE CAR STARTED SHAKING AND VIBRATING. FELT LIKE IT COULD BE A TRANSMISSION OR A ENGINE MISFIRE. MY CARS TRANSMISSION ALSO SHIFTS VERY VERY ROUGH KINDLY JERKY WHICH CREATES A UNSAFE ENVIRONMENT WHILE IN MOTION. THIS IS A CONSISTENT ISSUE AND WITH MY CAR AND ONLY HAVING 12,000 MILES ON IT I FIND REALLY CONCERNING. THIS VIBRATION ONLY HAPPENS BETWEEN 50-60MPH AND THE ROUGH TRANSMISSION SHIFTING HAPPENS AS I DRIVE IT ALONG WITH VIBRATIONS ARE COMING FROM THE ENGINE WHICH SHAKE MY ENTIRE CAR. ALL SERVICES ARE UP TO DATE. CADILLAC AND GM ARE BOTH NOT SURE OF WHAT THE ISSUE CAN BE EVEN THOUGH THERE IS A PENDING CLASS ACTION LAWSUIT FOR THE SAME ISSUE

EXTERIOR LIGHTING

1 complaint

THE CADILLAC DAYTIME RUNNING LIGHTS AND HEADLIGHTS EXCEED AMERICAN MEDICAL ASSOCIATION EYE SAFETY REQUIREMENTS OF 3000K COLOR TEMPERATURE OR LESS. THE CADILLAC LIGHTS ARE DAMAGING THE EYES OF DRIVERS OF ONCOMING VEHICLES AND OF PEDESTRIANS. THE GLARE CAUSED BY THE CADILLAC LIGHTS PREVENT DRIVERS OF ONCOMING VEHICLES FROM PROPERLY ASSESSING ROAD CONDITIONS AND SURROUNDINGS.
