2019 Cadillac Ats
Vehicle Specs & Maintenance Data
The 2019 Cadillac Ats maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Cadillac Ats.
For oil changes, the 2019 Cadillac Ats takes 5W-30 Full Synthetic motor oil with a capacity of 5 quarts. Brake fluid type is DOT 3, the recommended coolant is Dex-Cool (OAT), and transmission fluid is Dexron VI. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Cadillac Ats, torque the lug nuts to 100 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

CUE Infotainment Touchscreen Delamination and Failure
The Cadillac User Experience (CUE) capacitive touchscreen is notorious for screen delamination, where the screen layers separate and create bubbles, unresponsive areas, and a hazy appearance. This is caused by heat exposure breaking down the adhesive between the touchscreen layers. Virtually all 2013-2017 CUE-equipped Cadillacs will eventually develop this issue.
Replace the CUE touchscreen module. GM extended the CUE screen warranty to 4 years or 50,000 miles under Customer Satisfaction Program 14311. Aftermarket replacement screens are available for $200-$400 and can be installed in under an hour. OEM dealer replacement is significantly more expensive. Some owners install a screen protector after replacement to extend the life of the new screen.
Est. Cost: $200 - $400 (aftermarket); $800 - $1,500 (dealer OEM replacement)2.0L Turbo Timing Chain and Camshaft Actuator Issues
The 2.0L LTG turbo engine develops timing chain rattle and camshaft actuator solenoid failures. Symptoms include a rattle on startup, check engine lights with codes P0016 or P0011 (camshaft position correlation or actuator performance), rough idle, and reduced power. The exhaust camshaft actuator solenoid is the most frequent failure point.
Replace the camshaft actuator solenoid(s) as a first step if the codes indicate actuator performance issues. If timing chain stretch is confirmed, replace the chain, tensioner, and guides as a complete set. Use full synthetic 5W-30 oil and maintain strict 5,000-mile oil change intervals to prevent recurrence.
Est. Cost: $200 - $400 (actuator solenoid); $800 - $1,800 (timing chain set)Front Strut and Shock Absorber Premature Failure
The front struts and rear shock absorbers wear out prematurely on the ATS, sometimes as early as 40,000 miles. Owners report a noticeable decrease in ride quality, increased body roll, clunking over bumps, and the vehicle bouncing excessively after hitting bumps. The sport-tuned suspension option (FE3) is particularly susceptible to early failure due to its stiffer valving.
Replace front strut assemblies and rear shock absorbers. Consider upgrading to Bilstein or other quality aftermarket dampers that offer improved longevity. Inspect the strut mount bearings, which often need replacement at the same time. Perform a four-wheel alignment after strut replacement.
Est. Cost: $600 - $1,400 (all four corners)Sunroof Drain Clog and Water Leak into Cabin
The sunroof drain tubes clog with debris, causing rainwater to overflow and leak into the headliner, A-pillar, and footwell areas. Owners notice water stains on the headliner, wet carpet on the driver or passenger side, and a musty smell. Prolonged water exposure can damage the BCM, radio amplifier, and seat wiring harness.
Clear the sunroof drain tubes by blowing compressed air through each of the four drain tubes from the sunroof tray. Verify that all four drains flow freely by pouring water into the sunroof tray and confirming drainage. If the headliner is stained, it may need professional cleaning. Inspect and dry any electrical modules that may have been exposed to water.
Est. Cost: $100 - $300 (drain cleaning); $500+ (if electrical damage occurred)Rear Differential Mount Bushing Failure
The rear differential mount bushings deteriorate and crack, causing a clunking or banging noise from the rear of the vehicle during acceleration and deceleration. The noise is most pronounced during gear changes and when transitioning between acceleration and coasting. The worn bushings allow the differential to shift position, which also causes driveline vibrations.
Replace the rear differential mount bushings. Polyurethane aftermarket bushing upgrades are available and provide longer service life than the OEM rubber bushings. The differential does not need to be fully removed for this repair on most ATS models. Inspect the halfshaft CV joints and driveshaft center support bearing at the same time.
Est. Cost: $200 - $600
