The interior lights flash when you press the brakes
I just purchased a 2015 Tahoe and drove it off the lot only to discover the interior lights flashing every time I pushed on the brakes. It even did it when I put on my left turn signal. I noticed someone else had asked about the same issue and that it was a recall. I'm hoping I can call my salesman Monday and get it fixed, but I'm preparing for the opposite. I was wondering if you knew how much it cost to get it fixed?
My car has 57000 miles.
My car's transmission is unknown to me.

Hi there. It really depends on what the source of the electrical glitch is; which will determine the repairs needed. I’d wager that the issue is an electrical fault with the brake switch that is causing this. However, since you purchased the vehicle from a dealership, you should be provided with consumer protection and rights to return a vehicle with electrical issues. I wouldn’t worry too much about the dealership trying to charge you for these repairs. Remember as a consumer, you have rights.
How to Identify and Fix Common car Problems ?

Your brake lights and brake lights are on the same circuit and your battery is so weak that illuminating the brake lights lowers the voltage enough to dim the dash lights.
The most common reasons a Chevrolet Tahoe shakes when braking are bad brake rotors, bad brake pads, or a bad wheel bearing.
The most common reason a car trembles when braking is your brake rotors being warped. Brake rotors wear out around the 70,000-mile mark. Old brake rotors are thin, and damage-prone. One sign you need to replace them is your car shaking when braking.
When all your dashboard lights turn on at once, it most commonly indicates an issue with the alternator or the charging system. It is common for all the dash lights to come on with no alternator output; low voltage can cause unusual electrical issues. The alternator should be tested at the time of battery replacement.
But most commonly, LED bulbs may flicker or dim in your home when there are voltage fluctuations in your home`s wiring. When electrical loads turn on and off in your home, this creates a change in voltage levels, which may cause the LED lights to occasionally dim or flicker.
All the common LED bulb flickering issues have been solved with a PWM module. If you have just installed your LED lights on your car and you go to turn them on to only see nothing, you may have a polarity issue. This is super easy to fix. Just take out the bulb, flip it, and plug it back in.
A new set of brake pads may be the easiest way to address your vehicle`s brake shudder. However, in some cases replacing your brake rotors or having them resurfaced will fix the brake shudder. If you`re replacing brake rotors, it is recommended you also consider replacing the brake pads as well.
Brake shudder arises as a result of issues with the brake discs. Namely, when the brake discs have been affected by Disc Thickness Variation (DTV). This refers to the uneven wear of brake discs and is the result of rotor run out.
The most common reasons a Chevrolet Tahoe has rough idle are a vacuum leak, an issue with the spark plugs, or a problem with the ignition coil.
1) Your pedal vibrated because the ABS (anti-lock braking system) was activated. If the pedal vibrations (pulsing and groaning noises, too) happened when you e-braked, chances are ABS was activated. ABS prevents your tyres from locking up, which could lead to an uncontrollable skid.
The two coils are too close together, so if you are driving at night and hit the brakes on a bumpy road, the two coils can touch and fuse together. Because you cannot see your own rear lights, you dont realise all sorts of weird stuff is going on, side lights flashing, dimming, or even going out when you are braking.

EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.
When I put my foot on the brake my back left brake light goes off, when I take it off the brake the brake light comes on
I would suggest trying to disconnect and reconnect the wiring to the rear lights. I have seen these older Toyota vehicles rear lighting short out on the lights themselves due to the way the light circuit was made on the lamp housing. Look at the housing circuit on the light to see if one is touching another, and that could tell you why it is malfunctioning. There could also be a problem with the brake light switch. If you are not comfortable dealing with wires, I recommend getting in touch with a certified mechanic who can look at your brake light issue for you to see what’s going on.
Brake lights are not working. replaced brake light swtch still no brake lights. the third brake light the connection was melted at
The first thing to do is to repair third brake light and replace the brake light fuse and then see if the third brake lights work and the lower lights start working? If only the 3rd brake light starts working then you may need a further checks on the turn signal flasher or switch could be bad.
Brake sensor is to sensitive causing brakes to flicker while driving. 2005 Mercury Montego
Hi there – your brake light switch needs a minor adjustment. It is adjusted too "tight" or close to the brake pedal lever, or possibly has failed. Adjusting/replacing it will eliminate this flickering problem. I recommend a brake light isn’t working inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.
Rear brake light, and some interior lights don’t come on unless I’m braking
Hello. Replacing the stop light socket with a new one should have solved the intermittent problem of the stop light not working all of the time. It is possible that when you tweaked the socket, it caused a short to ground. This could explain why the dash lights only come on when you press the brakes.
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.
I have no brake lights and third brake light I have checked all fuses and brake pedal switch and the switch is fine and I’m still
Hi there. Well, you’ve listed most of the usual suspects including the brake switch, fuses and tail light assembly. However, one item you might want to also check is the accessory electrical relay. In some cases, the relay that supplies power from the brake switch to the tail light assembly will cause the issues you are describing. I always recommend that home mechanics purchase a service and repair manual for their vehicle to have a schematic accessibly, so it might benefit you to purchase one online to locate this relay or feel free to have one of our mobile mechanic some to your location and complete a brake light inspection, so they can help trace this issue for you.
First, the fuse 19 keeps blowing. When I hit the brake pedal my dash lights up. The third brake light acts like a running light.
Hi there. Check the wiring on the vehicle to the tail and brake lights. There is a cross short that is causing the lights to blow the fuses and make the tail lights brighter than normal. If you need further assistance with your electrical issues, then seek out a professional, such as one from Your Mechanic, to help you.
