Why is there a delay in starting the Cadillac CT6?

[BriannaLee]

In many cases, due to the condition of the vehicle, external environment, and other factors, a delay of a few seconds or minutes when starting the car is normal and may not require special attention, but it is important to pay more attention to maintenance. However, if the starting delay persists for a long time, it is advisable to have it checked at a professional flagship store. Below is a brief introduction to the model: The Cadillac CT6 is a mid-to-large luxury sedan, with only the 2019 model currently available for sale, divided into National V and National VI versions. The National VI version was launched in January 2019, available in both two-wheel drive and four-wheel drive variants. The dimensions of the 2019 Cadillac CT6 are 5223mm in length, 1879mm in width, and 1492mm in height, with a wheelbase of 3109mm.

I own a Cadillac CT6 and have also experienced delayed ignition issues before. That feeling is really annoying—you turn the key and wait forever for the engine to start. The most common cause is an aging battery. After a few years, the battery can't hold a charge well, especially in cold weather. Another possibility is a faulty starter, like worn carbon brushes or a stuck gear, which leads to insufficient RPM. I've also heard of fuel system problems, such as low fuel pump pressure or a clogged filter, preventing fuel from reaching the cylinders. Faulty sensors, like a bad crankshaft position sensor, can also mess up the ignition timing. I tried replacing the battery myself, and sometimes that works. But it's best to get a professional shop to check the electrical system and ECU—don't delay, because getting stranded on the road would be terrible. Regular battery checks and maintenance can prevent this. Safety comes first, after all—having unstable starts while driving is pretty dangerous.

Cadillac CT6 ignition delay is usually related to several major systems. As someone who frequently works on cars, I believe the engine control unit software may need an update, as data errors can cause command delays. In terms of fuel, if the low-pressure fuel pump has insufficient pressure or the fuel injectors are clogged with carbon deposits, an abnormal air-fuel mixture can also lead to slow ignition. On the electrical side, aging ignition coils or excessive spark plug gaps can weaken spark intensity. Battery health degradation is a fundamental cause, especially during winter when the starting load is high. It is recommended to read the fault codes to identify the specific issue, and avoid random repairs. Regularly replacing the air filter and fuel filter can maintain smooth air and fuel intake, reducing the occurrence of delays. With many electronic components in the car, maintenance records should not be overlooked.

My CT6 sometimes takes several seconds to start, which is really annoying. It's usually caused by insufficient battery power or aging, so try replacing the battery. Another reason could be a dirty fuel system, where low fuel pump pressure or a clogged filter prevents fuel from reaching the cylinders. Internal wear in the starter motor might also slow down the cranking speed. Faulty sensors, like the temperature sensor, can cause the ECU to misjudge the ignition timing. You can simply check the battery voltage yourself—if it's too low, charge or replace it. If that doesn't work, take it to a repair shop for a comprehensive diagnosis. Don't underestimate the issue; prolonged delays might leave you stranded. For maintenance, check related components every six months.
