2016 MERCEDES-BENZ CLA250 Complaints

My 2016 Mercedes-Benz CLA 250 has a check engine light for code P052E, which points to a broken crankcase ventilation valve. My car has only 59,000 miles on it, but this same exact part already broke once before and was replaced under the original warranty. Now, the replacement part has failed too. This proves the part is defective and keeps breaking. Mercedes-Benz already knows this part is defective. They gave a free 15-year or 150,000-mile extended warranty to fix this exact issue for free on the C-Class and other longitudinal M274 engine platforms. However, they are actively denying coverage for my CLA 250's M270 engine variant, despite the two vehicles sharing nearly identical engine blocks, matching subcomponents, and the exact same broken part. Because of this unfair engine code technicality, Mercedes-Benz is forcing CLA owners to pay thousands of dollars out of pocket for a recurring problem they fix for free on a C-Class. I urge the NHTSA to look into this engine loophole and force Mercedes-Benz to include the M270 engine variants under the 15-year/150,000-mile free repair program.

I believe that my vehicle is subject to Recall Campaign # 21V197000. The vehicle is a 2016 Mercedes-Benz CLA250. I've had to have this part ( Front Stationary Roof panel) adhered 5 times in the last 10 months. Mercedes refuses to acknowledge the above campaign #. Not only is this a safety risk to my self and other drivers, there is risk of water damage any electrical components. When this issue was brought to their attention I was told this was VIN specific and no recalls were attached to this vehicle. The photos are from 2 separate incidents. There are no warning lights. My vehicle has had at least 2 unbiased inspections and available upon requet.

My mechanic said that he believes there is a recall on a recalled part this was previously repaired per Mercedes notice of safety recall dated April 2018. The recall remedy provided by the manufacturer has failed to permanently fix the safety defect, and the vehicle remains unsafe to drive. "On certain Model Year (“MY”) 2014-2017 B-Class electric, MY 2012-2018 C-Class, MY 2012-2017 E-Class, MY 2014-2018 CLA, MY 2015-2018 GLA, MY 2016-2018 GLC, and MY 2013-2015 GLK-Class vehicles, an electrostatic discharge, when combined with a broken steering column module clock spring and an insufficient grounding of the steering components, could lead to an inadvertent deployment of the driver airbag. An inadvertent driver airbag deployment may cause a risk of injury to the driver and might increase the risk of a crash." Currently my airbag and horn do not work as a result of this defect and Mercedes said there is no current safety recalls, however this is the exact issue that was replaced and fixed before I purchased it. They want to charge me a $300 diagnostic fee, (when my mechanic has already looked at it), I am not wanting to pay the dealership for an issue that is clearly related to the recall issue that was not properly fixed. My car is a safety issue to myself and anyone if I drive it, my horn does not work, so that makes it hard to prevent accidents and my airbag, upon reading further online, could potentially deploy and CAUSE and accident.

My vehicle is exhibiting the same problem as MB Recall Campaign #2021070010 but my MB Vin is not included in the recall even though my make/model of car is on the list. This MB recall campaign is to replace the front stationary sunroof panel. According to recall,"The panoramic sunroof may not have been bonded correctly to the vehicle. The adhesion of the front panel might partially or fully detach from the vehicle increasing the risk/injury to other road users." This campaign which was updated 9/3/2021 should include ALL vehicles on the recall list that exhibit this issue. I contacted an authorized MB dealer show quoted me $2225.41 for a repair that we know is known DEFECT. PLEASE HELP!

Factory window tint of the back window & the driver/passenger side(s) windows are bubbling and peeling causing visual impairment while operating motor vehicle. Examples of impairment are backing the vehicle and changing lanes & these affected areas are blurry. Panaramic Sunroof does not seal properly when closed. Factory vehicle paint bubbling and peeling causing depreciation of the vehicle.

The incident that occurred is that my sunroof exploded on me while I was driving. There was know one in front of me nor next to me. Nothing hitting it to cause this, it just exploded.

Hi there - I know my vin number doesn't recall the front stationary roof panel replacement but this came to my attention as I saw that the panel has faded the top coating and the edges have some very thin cracks I will say. I was not aware of such a thing but googling the issue I found out that NHTSA did start a campaign for this particular safety issue last year. Campaign No. 2024010012, March 2024. My Mercedes falls completely on the requirements for repairing/replacing this front panel as the model, year, and type of material of this panel but yet no recall with my vin number. Just wondering if this is a mistake or something else that I don't know. For now I haven't driven the car for the safety concerns until I have any explanations. Your response in this matter will be very appreciated ! Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2016 CLA 250 having multiple electrical and driving issues that are not recalled. I’ve researched online and found most of these issues are common. 1. Dashboard screen and radio console lights turn off completely. USB connection triggers electrical symptoms. Front and Back seat window control (driver) triggers electrical symptoms and sometimes corrects the problems. Trunk opens by itself while parked and/or stopped at red lights. The instrument cluster has times multiple warning lights turn on and stay on. At times the fuel needle drops completely down as if I have no fuel in the car. The instrument cluster lights stay on after I have turned the car off and locked it as if the system is confused. I have more issues but those are a few to name. I also have video and pictures to prove these things happen randomly then the vehicle can go back to operating normally. I’ve taken it to service and all they have done is reset the warnings.
