6 known faults with sources
Engines: 1.4 MultiAir (Petrol)
MultiAir actuator starved of oil pressureValvetrain (MultiAir actuator)
- Engine / equipment
- 1.4 MultiAir (naturally aspirated and turbo) and the 0.9 TwinAir, which uses the same system: Fiat 500, Punto, Tipo, 500X; Alfa MiTo and Giulietta; Jeep Renegade and Compass; Abarth
- Period mentioned
- 2009–2024
- Symptoms
- Hard or rough cold starts, hesitation, stalling and an engine light with P1523 (low oil pressure in the MultiAir system).
- Possible cause described
- The intake valves are operated by oil pressure through an electro-hydraulic block. Degraded oil, a low level or a dirty secondary filter starve the system of pressure, and over time the actuator fails internally.
- Check for the garage
- Change the oil and filter with the correct specification, inspect the MultiAir mesh filter and measure oil pressure before replacing the actuator.
- Cost cited in the source
- Oil change: the cheapest step and often enough; MultiAir actuator: approx. €650–1,400 (converted from dollars)A rough figure from the original database, not an up-to-date quote.

Applies if: Only cars built up to 21/2/2020 without a drain hole in the silencer.
Won't start in frost because of frozen water in the silencer (500X, Renegade and Compass)Exhaust and emissions
- Engine / equipment
- Fiat 500X (2016–2020), Jeep Renegade (2015–2020) and Jeep Compass (2017–2018) built without a drain hole in the silencer
- Period mentioned
- 2015–2020
- Symptoms
- Below freezing the starter turns but the engine does not start; on days without frost it starts fine. More likely after short trips.
- Possible cause described
- Condensation water collects in the rear silencer and freezes, blocking the exhaust. FCA bulletin 09-004-20 (also valid in Europe) says to drill a 3 mm drain hole in the silencer.
- Check for the garage
- Ask the garage about bulletin 09-004-20 and whether the silencer already has the drain hole; until then, avoid leaving the car outside in frost right after a very short trip.
- Cost cited in the source
- Short garage job: drilling a drain hole; ask for a quote.A rough figure from the original database, not an up-to-date quote.

Applies if: Bulletin for Latin America, cars built up to 31/7/2019.
ABS and stability warning lights caused by oxidised or wet wheel speed sensorsBrakes / electronics
- Engine / equipment
- Renegade and Compass (II)
- Period mentioned
- 2018–2019
- Symptoms
- The ABS, stability control and engine warning lights come on together, especially after washing the car or in rain, and sometimes go off by themselves; codes C0031, C0034, C0037 or C003A.
- Possible cause described
- The wheel speed sensors oxidise or let water in. FCA has all four replaced (bulletin 05-001-20, October 2020) on Renegade and Compass cars built up to 31/7/2019 for Latin America.
- Check for the garage
- With the ABS light on the brakes work, but without ABS or stability control: drive carefully and go to the garage soon, where they can read the wheel sensor codes.
- Cost cited in the source
- No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Applies if: Weak points of this model from inspections, breakdown statistics and recalls; anything specific to one engine is stated in the sheet.
1.4 MultiAir turbo, oil dilution, 9-speed gearbox and campaigns on the RenegadeKnown weak points
- Engine / equipment
- Jeep Renegade (petrol, diesel and 4xe)
- Period mentioned
- 2014 onwards
- Symptoms
- The early 1.4 MultiAir turbo; oil dilution on the direct-injection petrols even at low mileage; a ZF 9-speed (4x4) that shifts badly from 4th to 5th; cracking door seals, wind noise and Uconnect faults; on diesels, typical high-mileage wear.
- Possible cause described
- Recalls (KBA): rear centre buckle (6/10/2014–21/1/2015), towbar (25/8/2014–25/6/2016), a 9-speed gearbox connection that could shift to neutral (2014–2015), an incorrectly updated airbag module (13/3/2018–6/4/2019) and curtain-airbag connectors (2020–2021).
- Check for the garage
- Check every campaign by VIN; check the oil level (dilution); test the automatic shifts.

- No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

View full entryEngines: 1.0 / 1.3 Turbo (Petrol)
Applies if: Brazil only; Renegade B1 MY 2022–2026 built up to 06/03/2026 with the 1.3 EYJ engine; TSB 14-002-26 and the specified DTCs. Not the 1.0 or other markets.
1.3 EYJ high-pressure fuel pump contaminationFuel system
- Engine / equipment
- Only the configurations, markets and VINs specified in each association.
- Period mentioned
- Specific production period stated in the condition and evidence.
- Symptoms
- MIL, rough idle or partial power loss with DTC P0087-00, P0088-00 or P0089-00.
- Possible cause described
- Debris in the pump can disrupt fuel pressure on vehicles covered by the bulletin.
- Check for the garage
- Confirm Brazil, EYJ engine, VIN and DTCs. Exclude if P0169/P0171. Compare actual/target rail pressure and low pressure: at 5.2–6 bar follow approved cleaning; replace pump and pipe only if unresolved. Below 5.2 bar diagnose low pressure and do not apply this repair.
- Cost cited in the source
- No verified estimate. Confirm repair eligibility and terms by VIN.A rough figure from the original database, not an up-to-date quote.

Applies if: Same Stellantis 4xe system; the sheet was documented on the Wrangler and Grand Cherokee 4xe.
Jeep 4xe batteryHigh-voltage battery
- Engine / equipment
- Jeep Wrangler 4xe and Grand Cherokee 4xe (plug-in hybrids)
- Period mentioned
- 2020–2025
- Symptoms
- Usually none. In rare cases, a battery fire, including when parked.
- Possible cause described
- Some cells may have a damaged internal separator. Stellantis has run several recalls since 2023, the latest in the US for about 320,000 cars; until a fix is available it asks owners not to charge them and to park outside. The repair is a software update and, if needed, a battery replacement.
- Check for the garage
- Confirm the recall status by VIN; if one is open with no fix, do not charge and park away from buildings.
- Cost cited in the source
- Free under the recallsA rough figure from the original database, not an up-to-date quote.
