After installing 2 new tires on the rear, the ESC Active light routinely comes on.
My car has 62200 miles.
My car has an automatic transmission.
Occasionally, these sensors can fail or become faulty working intermittently sending inaccurate signals to the ECU. When this happens, you may experience the symptoms you have described. The ABS or traction control system may be inadvertently activated by these false or inaccurate signals. To avoid any unnecessary repairs. I would suggest having a professional from Your Mechanic come to your home to diagnose your ABS and traction control system and service your ABS speed sensor as necessary.

Step One: Disconnect the positive cable from your car battery. Then, hold down the brake pedal to drain the vehicle`s electrical system. This will result in a reset of the car`s central computer. Plug the cable back in to restore power.

As you know, your car has sensors at each of the four wheels that monitor the tire pressure at each tire. When these sensors fail, you may notice inaccurate readings as to your tire pressure. In some cases, you may not receive any kind of indication. It may be possible that during the installation the tires did not seal properly causing a small and slow leak which triggered the sensor. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your tire pressure monitoring system.
The first thing that I would suggest is that the stop light socket be replaced. After replacing the stop light socket, if the dash lights still only come on when you press the brake pedal, the wiring for the dashboard will need to be inspected for any shorts to ground or bare wires touching metal that it shouldn’t touch. Since this issue started as a rear light problem, I would start with having your rear lights inspected by a certified technician, such as one from YourMechanic.
As a technician, I have access to reports from technicians across the country. I could not find any reports of this problem, so diagnosing this will require an experienced tech as this is not a common problem. In addition, this happens at intermittent times making it difficult to recreate. The most challenging part of this diagnosis will be recreating the symptom. I suspect it has something to do with the brake switch circuitry because it only seems to happen when you have your foot on the brake. I would begin my diagnosis there with a wiring diagram and test light in hand. The brake switch, instrument cluster, and environmental controls all interact with each other. Something is crossed either because of a failed module or damaged wiring in a harness.
Aside from making sure the coolant is full, this will not likely leave you on the side of the road. If you take it in to be diagnosed, be prepared for them to spend more time than usual to figure it out. Since it isn’t a key problem, you may need to live with it until it completely fails making it much easier to diagnose. Either way, I do recommend having a certified mechanic diagnose the warning light to make sure there isn’t anything serious going on.
Good luck.
