Recalls: Mercedes-Benz C117 CLA-Class
Overview
Manufacturers, or importers, issue recalls for defects or faults which have the potential to cause injury. Generally, manufacturers will inform the original buyers if their vehicle is subject to a recall and of the steps required to remedy the defect or fault. Please note that the recalls below (if any) are for Australian-delivered vehicles only. Furthermore, the number of recalls should not be taken as an indication of a model’s reliability or its safety more generally.
Recalls: Mercedes-Benz C117 CLA-Class
2014 Mercedes-Benz C117 CLA Diesel: oil leak
In January 2015, a recall was issued for Mercedes-Benz vehicles with the OM651 turbo-diesel engine that were available for sale during 2014. In these vehicles, the seal ring between the timing chain tensioner and the engine may leak oil – this could result in a hazard for other road users and, in extreme cases, a fire risk (PRA 2015/14509).
2015-16 Mercedes-Benz C117 CLA: loss of drive (fractured dual clutch)
In July 2016, a recall was issued for Mercedes-Benz C117 CLA-Class vehicles that had double clutch transmissions. In these vehicles, a welded seam in the transmission’s dual clutch assembly could fracture and cause a loss of drive – this could pose an accident hazard to the vehicle’s occupants and other road users. The recalled Mercedes-Benz C117 CLA-Class vehicles were available for sale from 1 November 2015 to 30 January 2016 (PRA 2016/15529).
2016 Mercedes-Benz C117 CLA: left window airbag may not deploy
In June 2017, a recall was issued for Mercedes-Benz C117 CLA vehicles that were available for sale in Australia from 1 October 2016 to 5 November 2016. In these vehicles, the left window airbag may not have been manufactured to specifications and may not deploy in the event of a collision, thereby increasing the risk of injury to vehicle occupants (PRA 2017/16114).
2016 Mercedes-Benz C117 CLA: front passenger airbag may not deploy as intended
In July 2017, a recall was issued for Mercedes-Benz C117 CLA vehicles that were available for sale from 1 October 2016 to 1 December 2016. In these vehicles, the propellant mixing ratio in the igniters of the front passenger airbag assembly may not meet specification. In the event of deployment, the front passenger airbag may therefore not deploy as designed, thereby increasing the risk of injury for the front passenger. For the recalled vehicles, the front passenger airbag assembly was to be replaced. For the VINs of the recalled vehicles, please seePRA 2017/16195.
2015-17 Mercedes-Benz C117 CLA: starting current limiter could overheat
In October 2017, a recall was issued for Mercedes-Benz C117 CLA vehicles that were available for sale in Australia from 31 January 2015 to 31 January 2017. If the starter were to become blocked due to prior damage and if multiple and/or extended start attempts were made, then the starting current limiter could be electrically overloaded and overheat. At worst, this could cause nearby components to ignite and cause a fire. For the VINs of the recalled vehicles, please see PRA 2017/16367.
2017 Mercedes-Benz C117 CLA White Art Edition: centre rear anchorage point missing
In August 2018, recall campaign RC2534 was issued for Mercedes-Benz C117 CLA White Art Edition vehicles that were available for sale in Australia from 3 July 2017 to 28 November 2017. In these vehicles, the top tether anchorage point for the centre rear bench seat may have been omitted, such that a child restraint could not be attached. For the VINs of the recalled vehicles, please see PRA 2018/16975.
2018 Mercedes-Benz C117 CLA-Class: front passenger airbag may not deactivate
In January 2019, recall campaign RC2594 was issued for 2018 model year Mercedes-Benz C117 CLA-Class vehicles that were available for sale in Australia from 1 March 2018 to 2 May 2018. In these vehicles, the automatic occupant detection function for the front passenger seat may not comply with specifications. If a rearward-facing child seat was installed in the passenger seat, the front passenger airbag may not be deactivated as intended and could therefore be deployed in the event of a collision – this increased the risk of injury for the child. For the VINs of the recalled vehicles, please see PRA 2019/17304.
2016-18 Mercedes-Benz C117 CLA-Class: front passenger seat detection
In August 2020, recall campaign RC2749 was issued for Mercedes-Benz C117 CLA-Class vehicles that were available for sale in Australia from 1 April 2016 to 28 February 2018. In the front passenger seat, an installed child seat may be identified as a person, or a lightweight person may be identified as a child seat. If the front passenger seat occupant was misidentified, then:
- The front passenger airbag may not deploy as intended, despite the presence of a person in the front passenger seat;
- The front passenger airbag may deploy, despite a child seat being installed.
In the event of a collision, there was an increased risk of injury or death to the person sitting in that seat in the event of a collision. For the VINs of the recalled vehicles, please see PRA 2020/18462.
2017 Mercedes-Benz C117 CLA-Class: faulty universal joint in the steering shaft
In July 2021, recall campaign RC2894 was issued for 2017 Mercedes-Benz C117 CLA-Class vehicles. A component in the universal joint of the steering shaft was not manufactured to specifications and this, over time, may impair the driver’s ability to steer the vehicle. If the steering did not perform as expected, there was an increased risk of a collision and therefore injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-001672.
2015-19 Mercedes-Benz C117 CLA with sunroof: panel between sunroof and windscreen may detach
In September 2021, recall campaign RC2885 was issued for 2015-19 Mercedes-Benz C117 CLA-Class vehicles with panoramic sunroofs. During a prior service repair, the panel between the windshield and the panoramic sunroof may not have been correctly bonded. The bonding may therefore deteriorate over time, such that the panel could partially or fully detach from the vehicle; this condition increased the risk of injury to vehicle occupants and other road users. For the VINs of the recalled vehicles, please see REC-004951.

Mercedes-Benz C117 CLA: ‘Power Steering Malfunction, Service Required’
In June 2014, Mercedes-Benz USA issued Service Bulletin LI46.35-P-059241 for Mercedes-Benz C117 CLA-Class vehicles with VINs preceding WD#117####N083207. After the engine was started, the instrument cluster may display the warning message ‘Power Steering Malfunction, Service Required’, an acoustic warning would sound and the steering would feel sluggish. Furthermore,
- No faults would be logged in the steering control unit; and,
- Fault code C063100 would be logged in the ESP control unit and fault code U013187 would be logged in the instrument cluster control unit.
According to the service bulletin, these symptoms could be due to:
- Faulty contact of power supply to the electric steering system; or,
- A component fault in the control unit of the electric steering system.
Initially, the power supply to the electric steering was to be checked. If the problem was still present, then the control unit/motor unit for the electric steering was to be replaced.
Mercedes-Benz C117 CLA 250 4MATIC: rear differential noise
In March 2015, Mercedes-Benz USA issued Service Bulletin LI35.40-P-060213 for Mercedes-Benz C117 CLA 250 4MATIC vehicles. Due to a fault with the internal differential assembly, a thumping, grinding or chatter noise may be heard from the rear differential when turning. To test, the electrical connector for the all-wheel drive solenoid valve was to be disconnected and the vehicle taken for a test drive; if the noise was gone, this verified the condition and the rear differential was to be replaced.
