Poorly fixed PTC heater earth cable: fire risk on the MG HS plug-in hybrid (EHS) in the MG HS
Yes: MG recalled the EHS (plug-in hybrid HS) because the PTC heater earth cable could be poorly fixed and come loose, with a risk of overheating and fire. The European alert (Safety Gate A12/00696/23, April 2023) covers units built from 20 January to 6 October 2022; the British DVSA extends the range from July 2020 to October 2022.[1][2]
Why this rating?
Critical severity: It can destroy the engine or gearbox, or affects safety.
Frequency occasional: It is a preventive recall: no source documents real fires for this reason. The European alert cites 24,627 vehicles worldwide (MG eHS and MG RX6, with no EU-only figure) and the DVSA 3,291 in the UK; a British analysis mentions more than 5,100 plug-in hybrid HS, without reconciling this figure with the previous ones. Being preventive, we have rated it occasional.[1][2][4]
Symptoms
- The sources do not describe prior symptoms; the DVSA only warns of a poor earth connection with a risk of overheating.[1]
Why it happens
The European alert attributes the problem to the earth cable not being well secured to the heating element and possibly coming loose.[2]
The DVSA specifies that the position of the PTC earth cable may not be well anchored to the bodywork, so the insulator is trapped between the cable and the sheet metal and creates a poor connection with a risk of overheating. A British analysis describes the cause as a badly fitted carpet affecting the PTC heater earth stud; we have not been able to reconcile both descriptions.[1][4]
If it is not repaired: The risk stated in the European alert is fire; the DVSA refers to overheating from the poor electrical connection.[1][2]
Affected years and cars
The European alert limits the campaign to units built between 20 January and 6 October 2022; the DVSA states production between 28 July 2020 and 27 October 2022 in the UK. The sources refer to the EHS (the Spanish press presents it as the 'PHEV sibling' of the HS) and not the petrol versions. We have not found how many units sold in Spain are covered by the campaign.[1][2][3]
How much it costs to repair
Includes: Inspection of the insulator and the earth cable anchorage on the PTC heater and correction if necessary, within the campaign.[1]
The sources consulted do not state the cost to the owner; the DVSA describes the remedy as checking the insulation and modifying it if necessary.
Prices in Spain, including VAT. A workshop hour costs on average €38–66 at independent garages and €77–134 at dealerships in Spain, depending on the region and the brand. How we calculate costs
How to check for it before buying a used car
- If the car is an EHS (plug-in hybrid) built between 2020 and 2022, ask an official MG dealer to check with the chassis number whether it is covered by the campaign and whether it has already been corrected; the European entry warns that not all units of the type are affected.[2]

Frequently asked questions
Which MG HS are included in the heater PTC recall?
The sources refer to the MG EHS, the plug-in hybrid version: built from 20 January to 6 October 2022 according to the European alert, and from 28 July 2020 to 27 October 2022 according to the British DVSA. As the entry itself warns that not all units are affected, the safe option is to check the chassis number at an MG dealer.[1][2]

- Critical severityFrequency: CommonRover 75Seat SRS connector fault with airbag and seatbelt warning light onAuto Express warns that the Rover 75's seat SRS connector can cause the airbags to fail, and dealers were fixing it with revised connectors. The Dutch APK inspection puts the airbag or seatbelt fault warning among the most frequent defects across almost all series.
- Critical severityFrequency: OccasionalAlfa Romeo GiuliettaShort circuit from badly routed wiring that can prevent gear shifting (KBA campaign, 2010-2015)Yes: according to Germany's KBA, on Alfa Romeo Giulietta cars built between 2010 and 2015 inadequate cable routing could cause a short circuit and, as a result, gear-shift failure.
- Critical severityFrequency: OccasionalAlfa Romeo TonaleFaulty wiring under the floor: loss of lights, power steering and brake servo (Tonale 2022-2023)Yes: a Safety Gate alert from March 2023 (campaign 6574) covers 607 Tonales built between 15 September 2022 and 13 February 2023, whose wiring under the floor can knock out the lights, hazard lights, power steering and brake servo.
- Critical severityFrequency: OccasionalBMW N62 / N63Additional turbo coolant pump with a risk of short circuit and fireIn 2011 BMW recalled 5, 6 and 7 Series, X5 and X6 models built between 2007 and 2011 because of the additional turbo coolant pump: moisture, a short circuit and, in extreme cases, a fire. In 2012 there was another campaign for a crack in the pump, with a more robust version.
- Critical severityFrequency: Occasional1.6 GDi híbrido (Kappa)Main relay of the power relay assembly (overheating and fire risk)Yes, on the first units: Hyundai and Kia recalled 2016–2018 Ioniq and Niro hybrids and plug-in hybrids because the main relay that connects the high-voltage battery could come loose, overheat and, in the worst case, cause a fire.
- Critical severityFrequency: Occasional1.6 GDi híbrido (Kappa)Clutch hydraulic actuator (HCA): leak or moisture with risk of short circuit and fireYes, this is the most documented hybrid system fault: the hydraulic actuator that engages the combustion engine with the hybrid assembly has had two recalls (2018 for a leak on the Niro and 2025 for moisture in its electronic board on the Niro, Ceed and XCeed PHEV), with a risk of short circuit and fire.
