Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest May 1, 2026
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

The screen goes blank not only in the middle where the maps, air conditioning and radio is but the screen where the speed gas tank are as well. We have taken the car in at least 5 times stayed the issue and were told there’s no recall yet for the car. I see here that there is. The car was a Richmond Mercedes today the screen went down amd I was told there’s no fix but maybe I could look on the internet. So here I am!

My vehicle's infotainment system both center console and dashbboard went completely black 2 weeks after I purchased the car in August of 2025. The vehicle was in the shop for a week and a half, and they finally fixed the issue. The vehicle at the time was bought used with about 2,200 miles on it at time of purchase. Now in July of 2026, exactly one year from the day i bought the car, with only 9,500 miles on it, we are having the same issue again with both the dashboard and center console going completely dark, not allowing us to see any critical information such as MPH, gas fuel, tire pressure, etc. Other than that the car seems to drive just fine. I noticed there was a mass recall of 144,000 cars because of this same issue with Mercedes Benz. The GLC-class was in fact listed on this list of eligible recall vehicles. However my VIN # was not eligible for some reason, even though it is the exact issue that the recalls were happening on, and fits within the recall class type and year of manufacture (2024-2026). I am simply requesting to be put on this recall list because it seems like this issue will continue to persist and we do not want to be turning this in every year and also risk our lives driving a car that does not give us very critical information in order to drive safely.

1 injury reported

In multiple incidents, the tailgate has begun to close while I am loading or unloading items from the trunk, hitting me in the head. My natural reaction is to lift up, causing injury to my neck. The dealer unsuccessfully "fixed" the problem. Additionally, and unrelated to the closing problem, on multiple occasions, upon pushing the close button on the tailgate when it was in an open position, the tailgate reaches the floor of the trunk, then without locking, opens about one (1) foot. The dealer "could not duplicate" the problem. I have to manually close the tailgate. You ask when did this happen, the latest incident is the date reported below, but the two issues/problems have reoccurred time and time again since we bought the vehicle new.

The contact leased a 2025 Mercedes-Benz GLC300. The contact stated that while driving at 45 MPH, the instrument panel and the infotainment system screen turned black, and the vehicle made abnormal electrical snapping sounds. The vehicle was taken to the dealer, where two software resets were performed days apart; however, the failure persisted. The dealer informed the contact that upon performing a third software reset and replacing the circuit breaker fuse, the vehicle would be repaired. The dealer and the manufacturer were contacted and informed the contact that it was a common failure. The failure mileage was approximately 4,700.

The infotainment and instrument panel screens blacked out after the vehicle was started a few miles away from our home. I was unable to see the speedometer while driving back home. This was the first time that this has happened to us. After a Google search of Mercedes Benz 2025 GLC 300, this event appears to be fairly common.

Crash reported

When I entered my vehicle after it was washed at the Mercedes-Benz service location, I pressed Memory 1 button and the seat returned to my normal position. Without any further input, I started the engine, and the driver's seat automatically moved backward by itself. When I readjusted the seat and shifted into Drive, it continued moving rearward. As the seat moved backward, my feet could no longer reach the brake pedal. At the same time, the car began to move forward, and I lost control of the vehicle, resulting in a collision that damaged the right side doors. This malfunction occurred suddenly and without any warning lights or messages. The seat moved by itself twice-once when the engine started and again when I shifted into Drive. The issue appears to be related to the seat's electrical control system or memory setting malfunction. The dealership has inspected the vehicle but was unable to determine the cause of the problem. I am deeply concerned that this may happen again and could cause a serious injury or major traffic accident. The vehicle has approximately 2200 miles and was purchased new in March 2025. I am requesting a formal investigation to determine the cause of this automatic seat movement and whether other vehicles of the same model are affected.

The entire main console display AND the digital instrument cluster screen have completely frozen. Additionally, the gas gauge for how much fuel is in the vehicle is nowhere to be found. Temperature touch controls (no physical option), volume, car settings (which can adjust safety features, multimedia features, accessibility features), etc. are all completely unavailable and unable to use. For example, if the defrost option was on which defaults to full blast heat, I would’ve unable to turn it off. The only information that is properly updating is MPH, headlamp status, time, Emerfency brake, Gear, and outside temperature. RPMs cannot be seen. Some of the pictures attached show that I’ve been on a phone call for 3.5 hours. I’m not.

LI82.60-P-080806

ELECTRICAL SYSTEM

Complaint After an "Over the Air" update (OTA), FM or SDARS radio reception is limited; only a few stations are found. Cause The firmware installation was incomplete. Remedy In the A26/17 control unit "MBUX multimedia system" (head unit), use XENTRY to carry out the special process "All Modules"; this will reinstall the firmware completely.

LI35.30-P-058566

POWER TRAIN

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).

ELECTRICAL SYSTEM

Complaint Traffic sign symbol for "Traffic Sign Assist" is blinking in instrument cluster without obvious cause usually with one of the following scenarios: • Flashing without a speed limit ("- -"). • Flashing when current vehicle speed is under speed limit. • Flashing between US speed limit symbol and European speed limit symbol. NOTE: • Verify that the concern falls under one of the attachment videos. If not, then it is outside of the scope of this LI. • This also does not cover "Traffic Sign Inoperative" messages on the instrument cluster. Cause There are two identified reasons for this concern: 1. Country code information stored incorrectly at a particular geographic latitude range. 2. Incorrect reference data when the vehicle is started and a GPS signal is not immediately available. Remedy Do not replace parts. Please open a TIPS case to the Body/Chassis/Entertainment inbox but read the below carefully: • The vehicle must be exhibiting the concern as shown in the attachment videos. • The vehicle DOES NOT need to be at the dealer, nor does it need to be brought into the dealership. • If the geographic location is known, it is very important that it is provided. • Provide any pictures or videos, if available. A new software for the head unit is scheduled for tentative release in Q3 2026.

Complaint Creaking noise, in irregular sequence when driving slowly in combination with slight steering movements and/or Creaking/crackling noises from the area of the wheel bearing on the front axle when cornering/ maneuvering. Sound file attached for comparison. MUST match noise for proper diagnosis. NOTE: Steering functionality is not affected. Cause Contact area between wheel bearing and steering knuckle. See also: LI35.30-P-058566 (Throttle Lift-Off Noise - Rear) LI33.30-P-056665 (Throttle Lift-Off Noise - Front) LI40.10-P-059248 (Wheel cracking noise when cornering) Remedy 1. Perform Operation A and evaluate by testing vehicle. 2. If noise is still present after re-testing: • If 192/232 chassis, verify FIN is in the listed range below in "Operation B" and perform. • If not 192/232 chassis or vehicle is a 192/232 not in the listed FIN range, additional verifications of where the noise is coming from are needed. Use multiple channel NVH method to narrow down location. Verify the LI's listed above were completed or if there are other similar noises associated with the chassis (Example: 192/232 also has under panel noises and an associated LI). Operation A: 1. Clean contact surfaces of wheel bearing and steering knuckle with brake cleaner as seen in the attached pictures. NOTE: The front area of the wheel bearing and the seals must not come into contact with the cleaner, otherwise, the sealing rings will be damaged. 2. Clean threads of wheel bearing mounting. 3. Thinly coat contact surfaces of wheel bearing, steering knuckle, and axle mating face with Molykote (annular joint grease). See the attached steering knuckle and wheel hub pictures for reference. NOTE: Axle mating face greasing is also covered in LI35.30-P-058566 and LI33.30-P-056665.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
