Is the 2014 Mercedes-Benz CLA250 reliable?

The 2014 Mercedes-Benz CLA250 has 147 owner complaints on file with NHTSA, less than half the median of 318 for 2014 sedans on this site. Of the 4 CLA250 model years since 2014, it has the most complaints. Complaint counts rise with sales as well as faults, so read what owners report below before deciding.

At a glance

Next to other model years: Complaints filed before 2015 aren't in the files this site reads, so the 2014 count runs short and isn't compared with the model years next to it.
Top problem: No problem dominates. The largest, stalling, covers 25 of the 147 complaints (17%), and traction control light is next with 15 (one complaint can fall under more than one problem, so these overlap). A quarter of the 20 owners who gave a mileage for stalling saw it by about 18,000 miles, and half by about 25,000.
Crash, fire and injury reports: 11 of the 147 complaints (7%) report a crash, a fire or an injury, about the 6% typical of vehicles on this site. Counted separately (one report can carry more than one), 5 reports mention a crash, 3 mention a fire and 6 people were hurt.
Recalls behind the top problems: No recall on file is on the same system as stalling. For those, the complaints are all there is.
When owners filed: Filings jumped in 2015, with 44 complaints, 2.0 times the next busiest year. So far in 2026, 5 more have come in. Filings on record start in 2015.

How this compares

2014 Mercedes-Benz CLA250147

Median 2014 model here (95 vehicles)304

Median 2014 sedan here (35)318

147 complaints is 2.1 times fewer than the median 2014 model on this site and 2.2 times fewer than the median 2014 sedan. Among the 1 CLA250 model years here it ranks 1st for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.

Airbags · model years 2014 to 2017

Desiccated air bag inflator rupture. Open.

NHTSA summary

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been n

Front roof panel detachment. Closed oct 14, 2021, led to recall 21V-197.

NHTSA summary

On January 8, 2021, after ongoing review with Mercedes Benz, the National Highway Traffic Safety Administration (NHTSA) Office of Defects Investigation (ODI) opened PE21-001 to assess allegations of front roof panel detachments while driving at highway speeds in certain 2015 Mercedes-Benz (Mercedes) C-Class vehicles.The subject front roof panel is a stationary panel composed of polycarbonate and is attached to the vehicle via adhesive at the time of manufacture. The panel is found on subject vehicles equipped with panoramic sunroofs. Over time, the subject panels may exhibit cosmetic degradation leading to replacement of the panel, a procedure which entails: removal of the old panel and adhesive, site preparation, and installation of a replacement panel with new adhesive.The consumer complaints that prompted the opening of PE21-001 all described detachments of front roof panels that had been replaced after the vehicle was put into service.Mercedes' internal investigation identified a broader scope of affected vehicles (2014-2020 CLA, GLA, C, S, GLC, and GLE class) and found the following potential service procedure- related causes of front roof panel detachments:- Improper surface pretreatments such as the use of the wrong primer or cleaner or scoring of the surface; or - Use of the incorrect adhesive.These conditions lead to a front roof panel bond that, even if sound at the time of repair, cannot maintain its strength over time and environmental exposure.Mercedes updated it
