2019 Cadillac CT6 Problems and Top Complaints – Is Your Car A Lemon?

Vehicle structure and brake issues among the top complaints received by the NHTSA from vehicle owners

Updated on Author: Brian Jones

Luxury sport sedans aren’t as easy to find these days, but the 2019 Cadillac CT6 continues to have a following. The automaker claims that this model helps to “Exceed expectations. Rapidly,” but owners are not in agreement. This vehicle suffers from a defective brake system and poorly-built structure.

Problems with the Brakes

Stopping power is one of the best things any car can offer. This 2019 Cadillac CT6 struggles to stop and puts a lot of people’s lives in danger.

Just read this NHTSA complaint. “The contact owns a 2019 Cadillac CT6. While driving, the brake system failed to engage. The vehicle was taken to an unknown dealer where it was diagnosed that the brake booster failed and needed to be replaced. The manufacturer was contacted and provided case number… The failure mileage was 1,800.”

There seems to be more going on with the brakes than meets the eye. NHTSA Campaign Number 19V889000 talks about how more than 460,000 vehicles suffer from Electronic Brake Control Module (EBCM) software error. This defect causes the Electronic Stability Control (ESC) and Antilock Brake System (ABS) to malfunction without the driver realizing it. Because of this issue, owners are at a higher risk of an accident, especially when attempting to brake. If this is how the automaker chooses to “exceed expectations,” they don’t aim very high.

Problems with the Vehicle Structure

There’s no denying that the Cadillac CT6 is a premium, luxury-focused automobile. The materials help owners feel like they are wrapped in high-class. However, many of the luxury amenities are only skin deep. As owners get behind the wheel and begin driving, they quickly notice that the structure, lights and other components aren’t built to the levels they should be.

As an illustration, have a look at another review on the NHTSA website. “Hello, on an estimated 8+ times, I put my vehicle into gear, drove off and both my side view mirrors were in the closed/up position. I have learned from GM support that GM did not develop software where the mirrors automatically open: when either opening the doors or putting into gear. This is extremely dangerous and I have never experienced on my former Mercedes E-350 leases, this safety technology was standard. The latest incident I was driving on a main west to east route for about 2 miles, needed to get into the right lane, went to look at my right mirror and it was completely folded up. It was very, very dangerous. Almost got me rear-ended since I braked hard when I noticed and I almost side-swiped the car to my right.”

It turns out that Cadillac didn’t think about a lot of things when designing this car model. NHTSA Campaign Number 18V673000 states that the rear seatbelt retractor might not lock because of a defect in manufacturing. If a child’s seat would happen to be buckled into these belts, it could lead to a catastrophe during an accident. Furthermore, another recall illustrates the level of incompetency occurring at GM. NHTSA Campaign Number 19V117000 says that the turn signals may not shut off on their own after turning. Instead, owners are driving around misleading other drivers and pedestrians while causing road hazards. While no one can agree that Cadillac is “exceeding expectations” at this point, it’s simple to get in line with part of the tagline. Customers are “rapidly” become fans of the Buick brand instead.

    This is alarming because I’m in the middle of purchasing a used/low mileage CT 6. I guess …, ” BUYER BEWARE “.
