1 Exterior Lighting problem of the 2010 Cadillac CTS

Failure Date: 03/08/2025

All of a sudden when I started my car, the lights flickered constantly, the power steering failed, and it blew my starter and fairly new battery. I was so scared; I thought it was going to catch on fire because it smelled burnt. And I was on [xxx] in hubbard ohio, and I was trying to get to [xxx] and safety to which I did. Thank goodness for aaa. I was told this happened because of a plug in wiring to heat or warm the washer fluid. It is available for inspection. My safety was impacted because, I had no power steering, flickering lights and smell of burnt stuff. My problem was fixed by an independent shop. My vehicle was not inspected by a gm dealer or my insurance. Was inspected by an independent shop that it was towed to. Warnings prior to incident: I would turn the ignition and nothing. But that would only happen several weeks apart. I thought maybe the starter was going, but it was odd because it was so many weeks far apart that it would happen. It might have been a total of 4 times since October of 2024. During the incident, power steering warning came on, charging system came on and the car sounded like it was barely running. Thank you information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

2 Exterior Lighting problem of the 2006 Cadillac CTS

Failure Date: 01/09/2024

The driver-side tail light lens fell off. I don't know where, but it probably fell off while I was driving, and if so, could have caused an accident. Cadillac does not stock this tail light assembly anymore, so I had to order it online, and then have it installed by a local shop. I am uploading photos of 1) repair invoice 2) new tail light box 3) old tail light (missing lens).

4 Exterior Lighting problem of the 2012 Cadillac CTS

Failure Date: 05/03/2021

I was sent a letter about the recall and I sent it back saying I could not afford to pay up front. The sent another letter about the deadline and I sent back I could not afford to pay up front. I never got a response back. My lights are getting dimmer and can't see at night. This is a safety hazard that I didn't cause and should have been required to repair. I bought the vehicle used and have a few payments left. This is a safety issue and it's inconvenient. This need to be investigated.

7 Exterior Lighting problem of the 2012 Cadillac CTS

I purchased a new 2012 Cadillac Cts in January, 2012. The car has been garage kept since new and has only 27,000 miles. Both headlamps recently began accumulating heavy condensation causing very dim lighting at night. This hazardous condition is clearly a manufacturing defect and not caused by excessive use of the vehicle nor exposure to the elements.

11 Exterior Lighting problem of the 2014 Cadillac CTS

Failure Date: 11/28/2016

I have a damaged right daytime run light on my 2014 Cadillac Cts. I have not been able to get the replacement part (part# 20896556). Gm now says there are non available in the system and have provided no help to secure one. This part fits 2014 thru 2016 Cts's. The vehicle is not safe to drive and Cadillac doesn't seem to thank it is their responsibility or care that they have created this safety hazard. My gm complaint number is 8-2572310479. I would think that the ntsb should be concerned that gm is doing nothing about this safety issue.

18 Exterior Lighting problem of the 2004 Cadillac CTS

Failure Date: 12/29/2012

January 29, 2012, vehicle headlamp went out. I observed condensation in the headlamp assembly. It was taken to the dealer who determined water had entered assembly and shorted out ballast and bulb on high intensity discharge headlamp assembly. Repair cost: $646. Approximately may 5, 2012, during rainy weather, same headlamp went out. Again, condensation in headlamp assembly. Bulb and ballast shorted out due to water. Required replacement headlamp assembly, repair cost in excess of $1200. Complained to gm, and they provided goodwill cost adjustment, but still had to pay an additional $671. I'm afraid the right side headlamp will do the same thing eventually. Gm needs to replace faulty headlamp assemblies on vehicles due to condensation caused by manufacturers defect in sealing the assembly during production. There appears to be a lot of issues with high intensity discharge headlamp assemblies on gm vehicles.

19 Exterior Lighting problem of the 2012 Cadillac CTS

Failure Date: 10/19/2012

While driving on a road with many curves at approximately 40 mph, I went to turn on the bright lights by pushing lever on left side of steering wheel outwards the bright lights came on as intended but at the same time I apparently hit the switch which controls the lights in different positions. The bright lights went off and I was left with parking lights only and could not see at all. There was no road shoulder as it was only one lane in each direction. I reduced my speed to 4 or 5 mph and did not know what I had done to cause this. There is no lights on the steering column and I had to watch the road so carefully that I had no or little time to understand why the lights went out. A car came up behind me and with his lights I finally had time to look down and move the light switch to its proper position. It was a horrible experience and something needs to be done to prevent this from happening again.

21 Exterior Lighting problem of the 2003 Cadillac CTS

The contact owns a 2003 Cadillac Cts. The contact stated that the rear tag panel detached from the vehicle and as a result, water was entering and damaging the wiring of the brake lamps. The vehicle was taken to the dealer who stated that the adhesive that was used to hold the panel was defective and needed to be replaced.

22 Exterior Lighting problem of the 2003 Cadillac CTS

Failure Date: 02/01/2012

While I was driving down the highway, I heard a loud noise, when I looked back the plastic piece which covers the two small lights around my license plate, had flown off and hit the car behind me. Fortunately there was no damage done, however the part obviously broke, and a new part costs anywhere from 750. 00 to 1000. 00 dollars (for a plastic piece that is no more then 28 inches long) every vender of this part I have called has told me it is so expensive because so many people have them fall off of their cars. There is no clips or screws to hold the part on, which means even if I buy another one the same thing could happen. My biggest concern is the car behind me.

23 Exterior Lighting problem of the 2010 Cadillac CTS

25 Exterior Lighting problem of the 2011 Cadillac CTS

Failure Date: 04/28/2011

This concerns the pwm frequency used on many led running lights being used on recent model cars. My wife is very sensitive to many of the new led running lights and refuses to drive at night because of them. The strobing of the led lights makes them appear to be in more than one place at the same time. This makes driving behind them and passing them very difficult for her. I don't notice it but she does and she will cover her eyes when we're out driving at night and get close to them. Reading on the internet, she is not the only one who complains about these lights. As and electronics engineer I understand how pulse width modulated drive circuits are used to control the brightness of leds as well as their color temperature. However, I see no reason for the low frequency being used in automotive applications. Certainly research has been done as to what pwm frequency is acceptable to 99. 9% of the population. I think that leds have a bright future, including in vehicular applications, and am all for their use. However, they need to be driven in such a way that doesn't compromise the safety of others on the road.

26 Exterior Lighting problem of the 2003 Cadillac CTS

Failure Date: 08/22/2010

The vehicle was taken to the dealer where the rear light module was replaced with a new, improved module. The back up lamps and the rear finish panel was also replaced with a safer panel. The manufacturer advised that the failure was not considered a safety hazard and would not provide any assistance. The contact believed the failure to be a manufacturing defect. The failure mileage was 50,556 and the current mileage was 50,700.

27 Exterior Lighting problem of the 2003 Cadillac CTS

Failure Date: 08/15/2010

The contact owns a 2003 Cadillac Cts. While driving approximately 50 mph, the rear overlay panel for the rear reverse light fell off.

29 Exterior Lighting problem of the 2006 Cadillac CTS

Failure Date: 10/04/2006

Automatic light sensor does not sense daylight for 5 mins and 23 secs at the last timing. In a daylight drive of 12 miles, the car turned night-time lamps on and off 6 times. Dealer says it is working as designed. This has just started to happen the last 12 days. No light settings have been changed since they were set when I purchased the car. I was told by sholz Cadillac repair to wait for the lights to sense the change before driving. However, what do I do when entering and exiting a tunnel? when placed side by side with a GMC xuv with an automatic sensor, the GMC senses the difference in light in 3 seconds. This delay in my Cadillac is certainly a safety hazard.
