⚠️ 1. Electronics and Infotainment

Among the most frequently reported issues with the Dacia Sandero (all series from 2014 to 2025) are those related to the Media Display / Media Nav multimedia system and connections with Android Auto and Apple CarPlay . Many users complain of touchscreen lag , sudden reboots, Bluetooth disconnections, or a general slowdown of the system. These behaviors, in most cases, are not caused by a hardware defect but by unstable power supplies or outdated firmware .

Most frequent symptoms

• 🎛️ Lag or screen freezes while browsing or booting the system
• 🔌 USB/Bluetooth disconnections (Android Auto or CarPlay dropping after a few minutes)
• 📶 Inaccurate or unresponsive touch , especially at high temperatures
• 🚗 "Nervous" parking sensors or false alarms on TPMS/lights

Most common causes

• ⚡ Weak service battery (voltage drops < 12.3 V) which causes electronic instability
• 🔧 Outdated firmware or interrupted update → communication errors between modules
• 🧲 Oxidized connectors or imperfect grounds → intermittent signal loss
• 📱 Unsuitable or too long USB cables → unstable data transfer

Recommended diagnostics: Run a battery test (≥ 12.5 V at rest), check for voltage drops during start-up, update the Media Display/Media Nav software to the latest version, and restore Bluetooth/USB connections by deleting saved profiles. In recurring cases, a complete system reset and cleaning the ground contacts under the dashboard or on the left side of the engine compartment are useful.

⚠️ 2. Stiff and noisy suspension

The Dacia Sandero Stepway , with its raised ride height and reinforced suspension, prioritizes stability on dirt roads and uneven surfaces, but exhibits stiffer and noisier handling than the standard versions. Many owners report sharp knocks on cobblestones and highway joints, creaking noises from the front end, and reduced comfort in city driving.

Most frequent symptoms

• 🔊 Sharp knocks on potholes or bumps, felt even at low speed
• 🎧 Localized creaking and clicking noises on the front side (especially when cornering or braking)
• 🛞 Increased stiffness on urban stretches or cobbled roads
• ⚙️ “Heavy” steering in parking lots or after prolonged cold stops

Most common causes

• ⚡ Shock absorber bearings and top mounts with play or hardened by time
• 🔩 Worn swing arm silent blocks → transmit vibrations to the frame
• 🧰 Stabilizer bar with bushings or dry joints
• 🚗 Tires with stiff sides or too high pressure (a common post-service mistake)

Technical solutions and improvements

• 🔧 Bridge check with dynamic play control of arms, bushings and top mounts
• 💧 Periodic lubrication of stabilizer bar joints and metal contact points
• 🧩 Replacement of the front silent blocks with reinforced or polyurethane versions
• 🛞 Keep tire pressure between 2.1 and 2.3 bar (cold) and choose comfort tires
• 🔄 Wheel alignment and tightening with the car in alignment to avoid residual noise

⚠️ 3. Interior quality: essential but improved

The Dacia Sandero has always remained true to its " functional before luxury " philosophy. The 2021–2025 versions show improvements in finish and comfort, but hard plastics , wind noise , and slight creaking noises remain after 40–50,000 km. These aren't serious flaws, but they're worth considering if you're looking for a quieter, more durable experience.

Most common symptoms

• 🔊 Creaking noises on the dashboard and door panels (more noticeable on uneven surfaces or in low temperatures)
• 🌬️ Air rustling noticeable above 110 km/h, especially in the area of ​​the pillars and mirrors
• 🎧 Resonances or vibrations on the central tunnel and luggage compartment
• 🪑 Front seats with slight flexing or noise when moving

Frequent technical causes

• 🔩 Assemblies with wide tolerances and clips that are not always perfectly tight
• 🧱 Hard, uncoated plastics that amplify vibrations
• 🚪 Door seals hardened or with small cracks in the joints
• 🔧 Door panels or dashboards with loose fixings after 3–5 years of use

Practical solutions and improvements

• 🧽 Apply sound-absorbing felts to door panels and behind the dashboard (noise reduction up to −30%)
• 🧰 Targeted tightening of panels with torque screwdrivers or replacement of deformed nylon clips
• 💨 Periodic treatment of the seals with silicone spray to avoid air hiss
• 🔊 Additional insulation on the floor and trunk with aftermarket sound-absorbing mats
• Lubricate seat guides and reclining levers with PTFE grease to eliminate squeaks

⚙️ 4. Hard manual transmission and difficult gear changes

One of the most controversial aspects of the Dacia Sandero (all generations, including Stepway and Bi-Fuel) is the manual gearbox . As the mileage increases, it can become hard or imprecise , especially when cold or when reversing. In most cases, these aren't structural defects, but rather degraded gearbox fluid , out-of-calibration selector cables , or loose engine/gearbox mounts .

🔎 Most common symptoms

• ⚙️ Hard or difficult gear changes in the first gears, especially when cold
• 🔊 Metallic noises or “scratching” when switching between 1st and 2nd gear
• 🚗 Reverse gear is difficult to engage without double-clutch
• 🪛 Abnormal play of the lever or “rubbery” sensation in the clutches

🔧 Main technical causes

• 🧴 Old or unsuitable gearbox oil → worsens smoothness, especially at low temperatures
• 🪢 Selector cables with excessive play or poorly adjusted
• 🧰 Worn engine or gearbox mounts → transmit vibrations and misalign the lever
• 🧩 Worn clutch or partially seized disc → noisy and difficult engagement
• ⚡ Low gear synchronizers fatigued after over 100,000 km

🧪 Rapid diagnosis recommended

1. Check the tension and travel of the gear shift cables – lubricate them and adjust them to their original values
2. Check the transmission oil level and color (it should be clear, not dark or metallic)
3. Inspect engine/gearbox mounts on axle: if cracked or loose → replace
4. In case of “scratching” → clutch test (slippage, disengagement point, noise in neutral)

🛠️ Effective technical solutions

• 🔄 Change gearbox oil with Renault/Dacia specification 75W-80 GL-4+ (2.1 L capacity)
• ⚙️ Adjust cables and grease friction points with lithium or PTFE grease
• 🧰 Check and replace the supports if you feel knocks or vibrations when releasing the clutch
• 🪛 Clutch recalibration or complete kit replacement if noisy or with abnormal travel
• 🧩 In extreme cases: partial overhaul of 1st-2nd gear synchronizers → evaluate cost/benefit beyond 150,000 km

⛽ 5. LPG system: maintenance, typical defects and solutions

The Dacia Sandero Bi-Fuel versions (petrol + LPG) remain among the most popular due to their low running costs, but require regular maintenance of the gas circuit . Over time, the system may exhibit sudden switching to petrol , difficult cold starts , or loss of power while driving. These symptoms, if ignored, can lead to significant expenses: however, it takes little to prevent them with a targeted periodic diagnosis.

🔎 Most common symptoms

• ⚠️ Sudden switch from LPG to petrol even with a full tank
• ❄️ Difficult starting when cold or with unstable idling in the first few minutes
• 🏁 Power loss during acceleration or gas “gaps”
• 💡 Engine light on with code P0171 (lean mixture) or P0172 (rich mixture)
• 💨 Gas smell when starting or after prolonged stops

🧰 Most common technical causes

• 🔧 Fatigued LPG reducer (hardened membranes or unstable pressure after 80–100,000 km)
• 🧩 Pressure and temperature sensors no longer accurate → incorrect switching between petrol and gas
• ⚙️ LPG injectors dirty or partially clogged with oil/paraffin residues
• 💻 LPG control unit map to be updated (not optimal calibration on some MY2019–2023 models)
• 🚫 LPG filters saturated or not replaced at the correct intervals (every 20,000–30,000 km)

🧪 Rapid diagnosis recommended

1. Perform an OBD reading : check for errors P0171, P0172, P2196, or P2198 (indicative of incorrect mixture)
2. Check the reducer pressure while running: it must remain stable (≈1.0–1.2 bar)
3. Analyze the switching behavior: the switch to petrol must be imperceptible
4. Check the LPG injection times → excessive differences between cylinders indicate dirty injectors
5. Inspect pipes and joints for any leaks or gas odors

🛠️ Technical solutions and preventive maintenance

• 🔄 Calibration and map update of the LPG control unit (eliminates sudden changes and improves starting)
• 🧴 Replace the reducer every 80–100,000 km to maintain stable pressure
• 🔍 Check pressure/temperature sensors → replace if values ​​are out of range
• 🧹 Cleaning or replacing LPG injectors → improves response and reduces vibrations
• 🧰 Check the tank and high pressure line → leak tests every 10 years as per regulations
