MERCEDES-BENZ Complaints

The panoramic sunroof spontaneously shattered. I was driving on highway under open sky and the sun roof just imploded and all the glass came shattering inside all over. There were no extreme weather or any construction or chances of any debris from anything around. No impact object could be identified upon inspection after the car was stopped.

There was an SRS Error message. The SRS system is non-functional on a vehicle with 400 miles. The dealership has attempted to fix the problem by replacing the fuse and control unit, but it appears to be a coding - programming issue. An engineering case has been opened for 2 weeks, but they have given me no notice of what or when the next step takes place.

2024 Mercedes-Benz Sprinter 2500 experienced unusually rapid brake, tire, and battery wear at low mileage. Front brakes required replacement at approximately 29,000 miles. Rear brakes were already worn low by approximately 37,000 miles. Rear tires required replacement by approximately 37,000 miles. Vehicle battery also failed and required replacement before approximately 37,000 miles. Vehicle had earlier emissions/sensor related repairs as well. This creates safety concerns because premature brake wear can reduce stopping ability and increase stopping distance. Premature tire wear can reduce traction, especially in rain, and increase risk of tire failure or blowout. Unexpected battery failure can disable the vehicle without warning in traffic or roadside conditions. Vehicle is used in normal commercial delivery service and is generally not heavily loaded. I have owned and operated multiple prior Sprinter vans over many years, and previous model years achieved substantially longer brake, tire, and battery life under similar or heavier use. A newer comparable fleet vehicle with similar mileage has not required these repairs. The issue appears abnormal compared with prior ownership experience and may indicate brake system drag, an alignment issue, defective components, battery charging issue, or another unresolved defect. Vehicle has been serviced by dealer and components were replaced, but premature wear remains the concern. In addition, rear brake wear occurring this early suggests possible imbalance or excessive brake application that should be investigated. Rapid tire wear combined with brake wear may indicate alignment or braking system issues affecting vehicle control and safety. I am submitting this complaint so the condition can be reviewed for potential defect trends affecting other similar vehicles. Defective parts may be available from prior repairs depending on service center retention.

Vehicle has ongoing and recurring electrical and engine-related defects that affect safe operation. The primary systems involved are the electrical system, engine ignition system, and powertrain. The vehicle is available for inspection upon request. Prior service records show issues beginning in 2020 involving repeated electronic system failures requiring multiple repairs and component replacements. Since purchasing the vehicle in April 2023, the vehicle has developed more serious failures, including: – September 2024: Check engine light with loss of power and inability to exceed safe driving speeds – October 2024: Engine misfiring due to ignition coil failure requiring replacement of ignition components – September 2025: Additional ignition coil electrical fault (code P0353) The problem has been reproduced and confirmed through dealership service inspections and diagnostic reports. Warning indicators, including the check engine light, appeared prior to failure events. These defects create a safety risk due to potential loss of power, engine failure, and unreliable vehicle operation while driving, which could increase the risk of an accident. The issues have required multiple repairs without permanent resolution and appear to be ongoing and worsening over time.

The contact owns a 2015 Mercedes-Benz C300. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the vehicle. The vehicle was driven to the shoulder of the road. The contact inspected the exterior of the vehicle and became aware that the moon roof panel had detached, and the moon roof panel flew off the vehicle. The dealer was made aware of the failure. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 21V197000 (Structure) in 2021. The contact was informed that the repair was not covered under warranty. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 62,612.

I am reporting a structural failure of the rear subframe (axle carrier) on my 2016 Mercedes-Benz C300 (W205). The component is exhibiting significant internal-to-external corrosion (perforation), specifically at the suspension mounting points. Safety Impact: The vehicle is currently exhibiting unstable handling and a 'skittish' 'swerving' sensation causing the car to 'fishtail' under braking during normal braking and at highway speeds, indicating a compromise in the structural integrity of the rear axle. This poses an immediate risk of a 'loss of directional control' should the suspension components fully detach from the corroded subframe. The Structural Integrity, Loss of Directional Control, Sudden Suspension Failure, and causes extremely dangerous Safety Hazard for my family and other on the road. The corrosion has compromised the mounting points of the rear suspension, creating a risk that the axle will detach while the vehicle is in motion, leading to a catastrophic loss of control. Context: Mercedes-Benz has acknowledged this defect in previous years (2008-2015) via a 20-year extended warranty and in Service Information S135.00-P-0009A. However, they have failed to include the 2016 W205 in the safety remedy despite identical failure modes and documented safety hazards. Currently, as of April 2026, a 2024/2025 federal court ruling [XXX] v. Mercedes-Benz) allowed a class-action lawsuit to proceed specifically covering 2010–2022 models—including the2016 C300 W205—alleging the exact same manufacturing defect. A thorough inspection of the undercarriage of the vehicle shows severe corrosion to the subframe as well as a cracked hub along the drive-train shaft and differential. I have submitted photos along with this Vehicle Complaint From to document the corrosion of the subframe and other defects associated with the devices and systems that transmit power from the engine or propulsion device to the wheels such as the cracks in hubs, shafts, differentials.

I am the owner/lessee of a 2023 Mercedes-Benz EQB 250+ (VIN: [XXX] ) affected by NHTSA safety recall 26V073 — a high-voltage battery fire risk defect that has failed three separate repair attempts. I am filing this complaint to document Mercedes-Benz USA’s failure to provide an adequate remedy under federal recall regulations. Background: Recall 26V073 was issued three separate times — first as recall 25V050 then 25V894 and finally 26V073. Each prior software remedy failed to resolve the underlying battery defect. Mercedes-Benz has now determined a full battery replacement is required. As of today no replacement battery is available for my specific vehicle VIN [XXX] . Current Situation: As a result of this unresolved recall I have been required to: • Park my vehicle outside and away from structures at all times • Restrict charging to a maximum of 80% capacity • Operate a fire risk vehicle for several months with no remedy available • Absorb $3,000 in home EV charger installation costs now largely unusable due to charging restrictions • Continue paying $22,000 in remaining lease obligations on a vehicle I cannot safely use Federal Compliance Failure: Under 49 CFR 573 Mercedes-Benz USA is required to provide affected owners with a free remedy within a reasonable timeframe. Mercedes-Benz USA has: • Failed to provide a repair — no remedy currently available • Formally declined to repurchase the vehicle • Offered $8,000 in goodwill compensation which does not constitute a remedy under federal recall regulations • Instructed my dealer Crown Eurocars in Pinellas Park Florida not to provide a loaner vehicle or storage assistance despite promising both in a written offer dated April 20 2026 Additional Bad Faith: Mercedes-Benz USA communicated a false claim to MBFS executive resolution team member Caroline stating that I had requested no further contact. I never made this request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car is not accelerating when I shift into drive or reverse. It says “reversing not possile-service required” error. Out the blue. There is a known recall on these model cars but Mercedes benz is saying its vin specific and mine is not covered even though I am experiencing the exact same issue. Recall date- 2017-02-07 Recall no. 17V078000
