2018 DS DS 7 Crossback problems
The 2018 DS DS 7 Crossback was sold with 3 engines and 1 gearbox that we have documented: the 1.2 PureTech, the 1.5 BlueHDi, the 2.0 BlueHDi and the EAT6/EAT8 gearbox. All of them have serious faults that affect the cars of that year. The safest option is the EAT6/EAT8 gearbox (verdict “With caution”). Outside the engine, 2 documented faults affect 2018 cars, such as incorrect or poorly secured airbag parts in two campaigns (2017-2018 and 2021).

What changes compared with the 2017 DS DS 7 Crossback
- Score: 5.5 → 5.2
- New engines or gearboxes: 1.2 PureTech
- Starts to be affected by: oil-bath timing belt degradation (1.2 PureTech) and excessive oil consumption from carbon on the piston rings or oil separator failure (1.2 PureTech)
1.2 PureTech engine in the 2018 DS DS 7 Crossback
Names: PureTech 130
- With caution
1.2 PureTech turbo 100-155 hp Euro 6.2/6.3/6d (2018-2022)
100–155 hp · EB2DT, EB2DTS, EB2ADTD, EB2ADTX
It has the pre-June 2022 belt and can suffer oil consumption from the separator; in return, almost all units are still within Stellantis's 10 years or 180,000 km of cover if the maintenance is documented.[3][4][5]
Faults that affect 2018 cars
- Critical severityFrequency: Very frequentTimingOil-bath timing belt degradationThe oil-bath belt on the 1.2 PureTech (2012-2025) can swell and shed debris that blocks the oil pump pick-up; without lubrication, the engine can be destroyed. Stellantis covers it up to 10 years or 180,000 km and asks for it to be changed every 100,000 km or 6 years.Repair (garage): €400–€800
- High severityFrequency: Very frequentLubricationExcessive oil consumption from carbon on the piston rings or oil separator failureThe 2014 to 2023 1.2 PureTech turbos can use too much oil: those from 2014-2018 through carbon blocking the piston rings and those from 2018-2023 through a defective oil separator. Stellantis considers more than 0.3 l per 1,000 km abnormal and includes it in its cover.
1.5 BlueHDi engine in the 2018 DS DS 7 Crossback
Names: 1.5 BlueHDi 130
- With caution
1.5 BlueHDi 75-130 with 7 mm chain (October 2017 - January 2023)
75–130 hp · DV5RC, DV5RD, DV5RE, DV5RCE, DV5RCF, DV5RUC
Worth buying if the chain campaign has been carried out and the servicing is documented with the required oil, because Stellantis's 10-year or 240,000 km cover depends on it, and that cover requires following the manufacturer's recommendations and presenting invoices.[7][8][9]
Faults that affect 2018 cars
- Critical severityFrequency: Very frequentTimingWear and breakage of the 7 mm chain between the camshaftsIn 1.5 BlueHDi engines built between October 2017 and January 2023, the 7 mm chain linking the camshafts can stretch and break, causing serious engine damage. Stellantis has recalled them and covers the fault for 10 years or 240,000 km.Repair (garage): €730–€820
- Medium severityFrequency: Very frequentEmissions controlAdBlue tank and pump failure1.5 BlueHDi engines built up to August 2020 can suffer failures of the AdBlue tank pump module, with a "no engine start" countdown. The whole tank is usually replaced and Stellantis contributes to the cost up to 8 years.Repair: €1,000–€1,500
- High severityFrequency: OccasionalInjectionSeizure of the high-pressure pump and injection systemSome early 1.5 BlueHDi engines have suffered seizure of the Bosch high-pressure pump, with juddering or the engine stalling on the road, sometimes before 50,000 km. The repair means replacing the entire injection system and the fuel tank.
2.0 BlueHDi engine in the 2018 DS DS 7 Crossback
Names: BlueHDi 180
- With caution
2.0 BlueHDi 177/180 (DW10FC/DW10FD, 2013-2021)
177–180 hp · DW10FC, DW10FD
In specific samples at this power level (23 reviews on the general 2.0 page and 14 testimonials for the Opel Grandland X) the turbo, DPF, EGR and injectors record very few cases; AdBlue is once again, proportionally, the most recurring problem.[11][12]
Faults that affect 2018 cars
- Medium severityFrequency: Very frequentEmissions controlAdBlue (SCR) tank and pump failureOn the 2.0 BlueHDi, the AdBlue tank can crystallise or fail and show a warning with a countdown to the point where the engine will not start. It is the most frequently cited fault of this engine: Stellantis compensates owners of diesels built up to August 2020, with no definitive fix.Repair: €1,000–€1,500
- High severityFrequency: OccasionalEmissions controlDPF clogging on short journeysThe additive-dosed DPF on the 2.0 BlueHDi can clog if the car mostly does short journeys and does not reach the temperature needed to regenerate. It is a documented fault on current models such as the Opel Grandland, although with fewer cases than on the generations of the 2.0 HDi from before 2013.
- High severityFrequency: OccasionalInjectionInjector and high-pressure pump wearThe injectors and the high-pressure pump on the 2.0 BlueHDi are among the documented faults, although in a minority of the cases recorded compared with AdBlue or the DPF. When the pump fails, metal particles can contaminate the whole circuit and make the repair far more expensive.
- Medium severityFrequency: OccasionalEmissions controlEGR valve blocked by carbon depositsThe EGR valve on the 2.0 BlueHDi can get clogged with carbon deposits and stick, causing juddering and limp mode. Specialists place the greatest risk in the earlier 120 and 136/138 hp versions without AdBlue; at 150-180 hp the documented cases are in the minority.Repair (garage): €200–€350
EAT6/EAT8 gearbox in the 2018 DS DS 7 Crossback
Names: 1.5 BlueHDi 130 EAT8 · 1.6 PureTech 180 EAT8
- With caution
EAT8 (AWF8F45, since 2017)
· AWF8F45
It is the most widespread version today, with the same documented pattern of jerking and hesitation, sometimes fixable with a software update, and, in a minority of cases, early failures that force a gearbox replacement; it is worth checking the history and testing the car both cold and warm.[14][15][16]
Faults that affect 2018 cars
- High severityFrequency: OccasionalElectronicsValve body failure leading to immobilisation or gearbox replacementYes, though in a minority of cases: there are documented failures of the EAT6/EAT8 valve body with limp mode, and several owners have had to replace the whole gearbox after very few kilometres, from around 4,200 km in one case.Repair: €2,000–€9,000
- Medium severityFrequency: CommonTransmissionJerking and hesitation when changing gear, especially when coldYes: several owners of EAT6/EAT8 models describe jerking or hesitation when changing gear, more often with a cold gearbox. It is usually down to valve body pressure or calibration, and the dealer often fixes it, though not always completely, with a software update to the control unit.Repair (garage): €1,000–€2,000
- Medium severityFrequency: CommonLubricationGearbox oil advertised as "lifetime" that is best changed preventivelyThe manufacturer does not include a scheduled EAT6/EAT8 oil change in the official maintenance, but several specialists recommend renewing it every 60,000-80,000 km: it degrades with heat and mileage even if sold as everlasting, and ageing fluid contributes to the jerking of the related fault.Repair (garage): €150–€400
Faults outside the engine in the 2018 DS DS 7 Crossback
- Critical severityFrequency: RareAirbags and safetyIncorrect or poorly secured airbag parts in two campaigns (2017-2018 and 2021)DS has recalled the DS7 Crossback in two airbag campaigns: one over an incorrect part fitted in the airbag device (built 2017-2018) and another over an incorrect mounting of the curtain airbags that could cause them to be ejected (built March-September 2021).
- Medium severityFrequency: OccasionalHeadlights and lightsWater ingress into the rear lights due to inadequate sealingSeveral DS7 Crossback owners, with different engines, document water getting into the rear lights because of inadequate sealing, with visible condensation and a risk of the light unit failing.
