2017 Tesla Model S Lighting Problems

Tesla originally confirmed issues with the MCU1 system in my vehicle and upgraded it to MCU2. I Paid $1,599 for the repair/upgrade. Since then, the center screen has continued shutting off while driving. When this happens, the instrument cluster and controls go dark, I cannot see my speed, use the blinkers to signal, operate the AC/defroster, or access other critical vehicle functions. This has occurred multiple times on highways, including US-22 in New Jersey, which created serious danger because I could not monitor speed or signal properly. Although Tesla addressed the MCU1 problem by upgrading me to MCU2, they told me afterward the vehicle was still “safe to drive,” despite the failures continuing. I believe this is unsafe because I lose visibility of all driving information and access to basic controls. Tesla now refuses to repair these ongoing problems. After I raised complaints about the severity of the issue, I was dismissed and mocked for my speech disability during phone calls, and Tesla placed me on a service restriction. As a result, I am unable to obtain further repairs for this safety defect. I am afraid to drive the car. No Adaptive Cruise Control, Automatic Emergency Braking, Blind Spot Warning, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance, Parking Collision Warning, or Rear Cross Traffic Warning features were involved in this failure.

Daylight Running Lights (DRLs) burned out, and Tesla charges exorbitant amounts to repair each DRL and headlight assembly, over $3,500 for each side. This is apparently a known issue with all 2017-2021 Tesla Model S vehicles, as it is widely discussed on Tesla owner forums. The DRLs are prone to repeated failures even after being replaced. Tesla will replace the DRL and headlight assembly as long as the vehicle is under warranty, but will not replace the failed DRL and headlight assembly after the warranty expires unless the vehicle owner pays for the replacement. This would seem to be a known chronic failure item, and since the DRLs are a safety feature, it would seem that Tesla should stand behind their vehicles and resolve this failure as a recall.

The daytime running lights dim and burn out after only a few year late and happen repeatedly even after the warranty has expired. It is a very expensive fix but is clearly a design problem because it looks to be happening across all models S’s

Tesla designs a single piece headlight with no serviceable parts. This includes headlights, high beams, and namely daytime running lights. All of these components are on an LED strip that overheats and un-solders due to this high heat, which causes premature failure. Some owners have reported as little as 3 months of life before failing. The daytime running lights are essential for safety driving in low light situations. These daytime running lights are seemingly built to fail. The lights dim then eventually no longer work. Tesla's solution is to have the customer purchase a brand new headlight at $1500. My vehicle is 4 years old and has been through 3 pairs of headlights already, when the last set burnt out I just left them as is. Tesla should either goodwill swap out these headlights for a non-built to fail component, or offer a repair for a quality LED strip with proper heat distribution. Without daytime running lights safety is a major concern on foggy, rainy, and low light situations. I have attached an image showing how the failure begins on top then slowly goes all the way down to the side of the headlight which fails later.

Right Headlight and running light failed. Can or replace bulbs. Tesla wants $1500 Ro replace a headlight!

The eyebrow on the drivers side needs to be replaced for the third time within 3 years. This is a safety issue for visibility.

Unknown My daytime driving lights for safety have begun to go out. It has been a long standing complaint but they refuse to fix mine under an expired warranty and I was quoted $1650 each to replace. I was told they would do a good will replacement but they will not. There are many complaints on the Tesla forums.

The LED daytime running lights are failing for the second time on my vehicle. By failing, I mean they are burning out and no longer effective. This is a well-known issue with Tesla vehicles, however Tesla is doing nothing to resolve the problem. The only solution offered is to pay for an entire set of new headlights which costs nearly $2,600. The replacement headlights eventually fail within 24 months. Not having daytime running lights could be a safety issue. Tesla is aware of the component failure however no recalls for this defective part has been issued. I believe most Tesla owners of the "refreshed" Model S experience a degradation of the LED portion of the headlights, which are the daytime running lights. Today I was quoted $2,582 to replace both headlights. My lights were previously replaced in 2019 under the original vehicle warranty. Is there anything that can be done to have the lights replaced under a recall or have Tesla cover the cost of the repair?

Headlight premature failure

I don't have this problem anymore because I had the circuit board replaced. The issue I have observed is the auto high beam feature doesn't work properly. They get stuck in the high setting and don't adapt to on-coming traffic. It's primarily in model y cars but all models have been observed. This might be as simple as needing the adaptive setting to be default or in my case a new control board replaced. The remedy before I got it fixed was to not have high engaged with the stock. I don't think there is a manual solution with the y or any newer teslas.
