What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2018 Cadillac CTS, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

What the reports in each category say, in the owners' own words

Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
THE TRANSMISSION "SHUDDERS". It does not happen with any regularity and with no advance warning. It may be electronic or mechanical or both.
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.

Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
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.

Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
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
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
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.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
