These are issues documented for the Opel Mokka in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

GM-Era Mokka A vs. PSA-Era Mokka B: Two Unrelated Engines, Separate Documented Risks
Engine (generation-dependent - see below) · severity: Moderate (Mokka A, P1101/low-power fault) / Critical (Mokka B, wet-belt and brake-vacuum-pump risk) - see related documented issues respectively for each generation's own real, separately-documented severity rating. · confidence: 58/100 · 5 cited sources

Symptoms to watch for
First-generation Mokka A (2012-2019, 1.4 A14NET turbo): reduced/low engine power with the MIL illuminated, consistent with a related documented issue's own documented P1101 intake airflow symptom pattern - see that card for the full, real diagnosis checklist (air-guide baffle inspection, PCV/crankcase check, intake carbon buildup check) before assuming a major internal fault
Current second-generation Mokka B (2020-present, 1.2 PureTech): cold-start visual belt-fray/cracking visible through the oil filler cap, and a SUDDEN, TOTAL loss of brake-pedal assist as a distinct, separate safety hazard - see a related documented issue's own critical safety warning and diagnosis steps in full before applying any finding here
This card's own real, honest disclosure: no Mokka-A-specific or Mokka-B-specific direct case (forum post, workshop report) was found in this research pass beyond the engine-code-family matches described above - both cross-referenced findings rest on confirmed engine-code identity, not a documented Mokka-badged incident
What To Check
Generation identification itself (year, VIN, badge, engine bay layout) is immediately checkable before any test drive. Once generation is confirmed, see related documented issues own buyer-detectability notes for that specific defect's own test-drive detectability.
P1101 Intake Air Flow System Performance Fault, presenting as reduced/low engine power
Engine (intake/airflow management) · severity: Moderate - a real, diagnosable driveability fault with multiple documented recoverable causes, none of which point to catastrophic internal engine damage, though it can produce a genuinely severe power loss/limp-mode symptom while present · confidence: 56/100 · 5 cited sources
Applies to: 1.4L A14NET turbo (103kW) / 1.4L B14NET turbo (revised) - not every engine this model has been sold with
ⓘ Not yet individually classified
What To Check
The core symptom (reduced/low power, MIL illuminated) is genuinely detectable on a normal test drive and cold start. Which of this card's several real candidate causes is actually responsible is NOT distinguishable on a test drive alone - it requires a scan tool read of the actual stored code plus the physical inspection sequence in this card's own diagnosis steps.

Questions South African Buyers Ask
Is the Opel Mokka reliable?
It depends heavily on which generation: the GM-era Mokka A and the PSA-era Mokka B use two completely unrelated engines with separately-documented risks. The Mokka A's documented issue (a P1101 intake airflow fault causing reduced power) is Moderate severity and generally recoverable; the Mokka B's own separately-documented wet-belt and brake-vacuum-pump risks are rated Critical.
Evidence: Not yet individually classified · last reviewed 2026-09-07
Confirm which generation (Mokka A vs Mokka B) before relying on either finding - they do not share engines or risk profiles.
What to check: Confirm the generation and engine before assuming either risk profile applies, and ask specifically about the timing-belt/wet-belt service history on a Mokka B.
On the earlier Mokka A, a documented P1101 intake airflow fault can cause reduced or low engine power - a diagnosable, recoverable fault with multiple documented causes, none pointing to catastrophic engine damage. The Mokka B (PSA-era) has its own separate, more serious documented risks (wet-belt and brake-vacuum-pump) not covered by this specific finding.
Evidence: Not yet individually classified · last reviewed 2026-09-16
This specific P1101 finding applies to the Mokka A's engine/intake system - confirm generation before relying on it.
What to check: If the car shows reduced power or a limp-mode symptom, ask whether a P1101 fault code has been diagnosed and what caused it.
What should I check before buying a used Opel Mokka?
First confirm which generation you're looking at - Mokka A or Mokka B - since they use unrelated engines with different documented risks. For a Mokka A, ask about any history of reduced-power or limp-mode symptoms. For a Mokka B, the documented risks are more serious and centre on the timing (wet) belt and brake vacuum pump.

General buying guidance for the documented Mokka profile - not a diagnosis of any specific vehicle.
What to check: Ask the seller which generation and engine the car has, and request service history relevant to that generation's own documented risk.
This guide summarises documented, sourced findings for the Opel Mokka generally. It is not an assessment of any specific vehicle - mileage, service history and condition vary by example.
