1. Engine Misfire and Stalling – 2016-2018 Cadillac CT6

When your 2016-2018 CT6 engine starts sputtering or stalling, it’s not just annoying—it’s a serious problem. That smooth Cadillac ride can feel jerky, unreliable. Often, the culprit is a faulty fuel injector, worn-out spark plugs, or an ignition coil that’s failing under pressure. These parts are supposed to fire up with precision, delivering that effortless power, but they’re not pulling their weight.

Solution: Our team digs deep into diagnostics. We find the exact failing part, replace it with Cadillac-grade components, and give your engine the tune-up it deserves. With fresh ignition coils and spark plugs, your CT6 goes back to the smooth, powerful ride you know and love.

2. Transmission Shudder and Hard Shifts – 2017-2020 Cadillac CT6

Transmission shudders? Hard shifts? In a luxury car like the CT6, that’s the last thing you want. Cadillac’s 8-speed automatic transmission, particularly in the 2017-2020 models, sometimes develops friction issues that make gear shifts rough. This isn’t just annoying; it’s a sign your transmission fluid may have lost its edge, causing metal parts to grind more than they should.

Solution: At Fremont Foreign Auto, we do a full transmission flush, replacing the old fluid with premium, Cadillac-approved fluid. If the issue persists, we’re ready to go further—checking the torque converter and other parts for wear. Smooth, flawless shifting restored.

3. Electrical System Draining the Battery – 2016-2019 Cadillac CT6

The 2016-2019 CT6 models are known for electrical problems. You go to start the car, and the battery’s dead—again. Why? Often, it’s because something, like the infotainment system, is still drawing power even when the car’s off. Over time, this drains your battery, leaving you stuck when you need to be on the road.

Solution: Our electrical experts at Fremont Foreign Auto go component by component to find the power-drain source. Whether it’s a faulty module or software glitch, we fix it. We reprogram systems, replace any fried components, and if needed, set you up with a new high-performance battery. Problem solved.

4. Turbocharger Troubles – 2016-2018 3.0L Twin-Turbo CT6 

Your 3.0L twin-turbo CT6 should feel like a rocket. But if your 2016-2018 model is hesitating, struggling, or smoking from the exhaust, you could have turbo issues. Turbos can fail from oil leaks, overheating, or clogged filters that choke off the airflow these powerhouses need. If left unchecked, it gets worse, and fast.

Solution: We inspect, clean, and, if necessary, replace your turbocharger with Cadillac-approved parts. We ensure every seal is tight, every filter clean, so your CT6 performs like a turbocharged dream. Back to full power, no smoke, no hesitation.

5. Brake Pad and Rotor Wear – 2017-2019 Cadillac CT6

Hear that? Squealing, grinding, or vibrating when you press the brakes? That’s a sign your 2017-2019 CT6’s brakes are worn. The CT6’s weight and power put a load on its braking system, causing brake pads and rotors to wear out faster than expected. Ignoring it can be costly—and dangerous.

Solution: At Fremont Foreign Auto, we replace worn brake pads and rotors with high-quality, durable alternatives that can take the heat. We even flush and replace brake fluid to give you smooth, safe braking that doesn’t just perform—it lasts.

6. Infotainment System Glitches – 2016-2020 Cadillac CT6

If your CT6’s touchscreen freezes, navigation loses its way, or Bluetooth won’t connect, it’s more than just frustrating—it’s a known issue in the 2016-2020 models. Cadillac’s infotainment systems sometimes glitch due to software bugs or outdated firmware. And when tech fails, it can affect everything from safety features to GPS.

Solution: Our team at Fremont Foreign Auto handles software updates and resets to get your infotainment back on track. We troubleshoot system glitches, ensuring everything works seamlessly. No more blank screens, no more lost connections—just smooth tech that keeps you connected.

7. Oil Leaks and High Oil Consumption – 2017-2020 Cadillac CT6

If your oil light keeps popping on, or if you’re noticing spots on your driveway, that’s a sign of trouble. Cadillac CT6 models from 2017-2020 can suffer from oil leaks, often caused by faulty seals or gaskets. Left unchecked, oil leaks lead to lower performance, engine wear, and even overheating.

Solution: At Fremont Foreign Auto, we inspect and replace worn seals and gaskets, eliminating leaks and restoring your engine to full health. And we top it off with Cadillac’s recommended synthetic oil for maximum protection and performance. Leak-free and running clean.
