GMC Acadia Lighting problems by year

I own a 2024 GMC Acadia that experienced a failure of the driver's-side rear turn signal. The problem first appeared on August 23, 2026, when the turn signal began flashing abnormally fast (hyperflashing), indicating a malfunction. The vehicle had approximately 60,433 miles at the time of the repair. The driver's-side rear turn signal was malfunctioning, creating a safety concern because other motorists could not reliably see my intention to turn or change lanes. This increased the risk of a collision,...

The center console infotainment system is too dim to see during the day leading to distracted driving during daylight hours trying to use it's controls that are very difficult to see especially while driving.

On September 26th, 2026 I got a random notification about needing to get my rear left turn signal checked out as it still functions but blinks rapidly. Today, September 28th, 2026, I visited my local dealership for the issue and was informed that they had received a bulletin regarding the concern but that instead of covering the defect tied to a "software anomaly", I was told it would be around $600 to replace. I feel this is a strong enough safety issue that should be considered for a recall as this is a widespread problem and should be covered by GM.

Shift to park Malfunction again, 4 th time!! 1000$ to fix is ridiculous

Back up camera randomly stops working (black screen-completely gone, or blue screen). Dash will randomly dim on its own and does not go back to normal unless car is shut off and turned back on. adaptive cruise control will disengage for no apparent reason. stabilitrak will flash on screen but no other indicators or reasons; nothing happens with car. Occasionally the blind spot mirror lights will not light up when vehicle is present.

This is ongoing from the purchase of the car. 1) Infotainment computer screen daytime illumination is so dark as to be a major safety issue as it causes too much time looking away from the road to operate the system. If you wear sunglasses you cannot see the screen at all. The dealer says nothing can be done to improve the problem. 2) Right rear tail light stopped working after 500 miles. Replacement requires dropping the rear bumper and quarter panel. The dealer actually damaged the body of the car while...

The contact owns a 2014 GMC Acadia. The contact stated that for several years, the headlight bulbs were replaced several times. The contact used several different brands of headlight bulbs, but the bulbs failed prematurely. The contact stated that the headlight bulbs were dim while using the low beam or the high beam headlights. Additionally, the turn signals failed to properly operate while engaging the turn signal lever. The contact stated that the sound for the turn signals was occasionally inoperable. The...

Daytime Running light bulb and housing failure. Some 2012 Acadia models recalled under now expired recall for bulbs and deformation of surrounding housing. Apparently the above recall was excluded from this recall and should have been included. Both DRL on this vehicle have failed and surrounding housing has been damaged . Subsequently replacing just bulbs is not possible. The housing melted on the bulb. Photo is available on request. This failure should be considered a fire hazard. GM customer service center...

I experienced the brakes squeaking on and off for a few weeks this past summer. When at the dealership for an oil change, I was told the brakes pads were still good and the squeaking is common, especially during hot humid weather. Since then, I have lost the brakes twice. Both times, the pedal went all the way to the floor without resistance and after a few seconds, they came back like nothing happened. There was no warning at all. I have also experienced a complete blackout on my dashboard for about 30 minutes...

I have had 3 taillights replaced. The first one was the driver's side taillight at Marty's GMC in Kingston MA. The second one was the passenger side taillight at Quirk GMC in Braintree, MA and the third one was the driver's side one again. the vehicle had approximately 28,000 miles when the 3rd taillight was replaced and was purchased in August of 2024. Both dealers stated that it was safe to drive the vehicle with the taillights not operating. The first 2 took approximately one week to get the part and the 3rd one took 4 weeks. I believe that this is a serious safety issue as the vehicle tailgate lights are only visible when directly behind the vehicle.

The contact owns a 2015 GMC Acadia. The contact stated that the center taillight was inoperable. The halo light was working as designed and then ceased operating. The headlights also became inoperable. The vehicle was taken to an independent mechanic, who replaced the bulbs and the headlight assembly. The rear signal light was blinking fast, and the light became inoperable. The message that the hood was ajar was displayed. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that there were no recalls on the VIN related to the failure. The failure mileage was approximately 196,448.

The driver and infotainment center is so dim during the day that it is dangerous to drive the vehicle. I have taken the vehicle in to the dealer 3 times and each time the dealer indicates that there doesn't appear to be a problem, but at no time to my knowledge have they taken the vehicle out into the sunlight, There have been 2 Software updates at the dealer and one OTA update so far with no improvement. The screens are so dim that there is no way you can tell what icons are there. If you try to do anything...

Rear driver's side brake light/turn signal is out. This is the second time in under a year. Local GMC dealer is not able to replace it within a reasonable amount of time causing a safety issue. This is a well known issue to GMC which is why the part is on back order. No other dealers in my area have the part in stock.

My 2025 Acadia Denali's Main tablet sized screen is impossible to view in bright daylight. This screen has controls for most of the vehicle's settings. If I want to change something such as the temperature setting, I can't see the proper button. This is clearly a safety issue as taking eyes off the road for an extended period just to make a simple setting change is a recipe for disaster. My dealer claims there is no solution as they are all like that.

The contact owns a 2024 GMC Acadia. The contact stated there was an abnormal squeaking sound coming from the vehicle while depressing the brake pedal. There was no warning light illuminated. The vehicle was taken to a dealer and the brake pads were replaced; however, the failure returned several days later after the repair. In addition, the contact stated that transmission fluid was leaking from the vehicle. The contact also stated that both taillights had failed to operate as needed and the message "Check Left...
