All 7 Known Issues
The Ford Transit 350/350 HD with the 3.5L EcoBoost twin-turbocharged V6 experiences turbocharger failures from inadequate lubrication, carbon buildup in the turbo housings, wastegate actuator failure, and turbo bearing wear. OMS AutoParts and Autodoc document common Transit turbo problems including loss of power, turbo lag, unusual whistling/whining/grinding noises, and excessive smoke. The commercial use of Transit vans (frequent stop-and-go, high idle hours, heavy loads) accelerates turbo wear beyond what passenger vehicle applications typically experience. FordTransitUSAForum.com documents a case of turbo and manifold failure at 38,000 miles on a 3.5L EcoBoost Transit 350. RepairPal estimates turbocharger assembly replacement between $1,650 and $2,210 depending on the Transit model variant.
Common Symptoms
- Loss of power or reduced boost
- Excessive turbo lag (slow boost response)
- Whistling, whining, or grinding noise from turbo area
- Excessive blue or black smoke from exhaust
- Check engine light with boost-related codes
- Oil leak from turbo drain or feed lines
- Burning oil smell from engine bay
- Reduced fuel economy
How to Fix
For wastegate actuator failures (most common turbo issue): replacement of the actuator alone ($200-400) may resolve boost control issues without full turbo replacement. For internal turbo bearing failure or impeller damage, complete turbo replacement is required. RepairPal estimates $1,650-2,210 for turbo assembly replacement. For Transit commercial vehicles, change oil every 5,000 miles (not the factory 10k interval) and allow 30-60 seconds of idle time before shutdown after sustained driving to allow turbo bearing oil to circulate. Never shut off a hot turbocharged engine immediately after towing or hard driving.

Parts and tips from 1,200+ owners who fixed this issue
- TipFor commercial Transit vans with the 3.5L EcoBoost: change oil every 5,000 miles maximum, NOT the 10,000 mile factory interval. Commercial stop-and-go driving with heavy loads degrades oil faster than the oil life monitor predicts. Clean oil is the #1 factor in turbo longevity.
- NoteNever shut off a turbocharged Transit immediately after towing, highway driving, or heavy load. Let it idle for 30-60 seconds to allow oil to circulate through the turbo bearings as they cool. Immediate shutdown allows residual heat to "coke" the oil in the turbo bearings, accelerating wear.
The first-generation 3.5L EcoBoost (2011-2016) used in the 2015-2017 Ford Transit 350/350 HD with the twin-turbocharged V6 is known for premature timing chain stretch. The single-chain-per-bank design (two chains total) stretches as the links wear individually, causing the chain to effectively grow longer. A stretched chain causes VCT timing correlation codes, cold-start rattling, rough idle, and eventual jumped timing. Ford revised the 3.5L EcoBoost design in 2017 to use dual chains per bank (four total), which substantially resolved the stretch issue. Transit vans used for commercial/fleet service with high-idle hours accumulate chain wear faster than typical passenger vehicles. The F150 EcoBoost Forum documents thousands of cases of this specific 3.5L chain issue and contains multiple long-running troubleshooting threads.
Common Symptoms
- Cold-start rattle from engine (first 2-5 seconds on startup)
- Check engine light with P0016, P0017, P0020, P0021 (cam-crank timing correlation)
- Rough idle, especially when cold
- Poor fuel economy
- Engine hesitation or stumble
- Loss of power under acceleration
- Drivability issues that worsen over time
How to Fix
Complete timing chain replacement required: both primary chains, all guides, and tensioners must be replaced simultaneously. In 2017+, Ford redesigned to dual-chain design which resolved the issue. Remanufactured short block or long block replacement is an option for high-mileage engines if chain guides have also failed. Use only 5W-30 full synthetic and change every 5,000-7,500 miles. Labor: 10-14 hours on Transit due to engine mount complexity.
What Owners Are Using
Parts and tips from 870+ owners who fixed this issue
- NoteWhen replacing the timing chain on a 1st-gen 3.5L EcoBoost Transit, replace ALL chains, ALL guides, and ALL tensioners at the same time. Reusing worn guides with a new chain causes the new chain to wear rapidly and fail again within 20,000-30,000 miles.
- TipFord redesigned the 3.5L EcoBoost with dual chains per bank starting in MY 2017. If you have a 2015-2016 Transit 350 with the 3.5L EB and it currently has no rattle, consider replacing the chain as preventive maintenance at 80,000-100,000 miles regardless.
- TipUse only 5W-30 full synthetic oil in the 3.5L EcoBoost Transit. Change it every 5,000 miles - the extended oil life monitor intervals are NOT appropriate for high-load commercial van use. Clean oil is the #1 factor in chain longevity on this engine.
The 1.6L EcoBoost engine in 2014-2018 Ford Transit Connect has documented issues with coolant loss, overheating, and in severe cases engine fires. Ford issued Recall 14S11 (NHTSA 14V309) for 2013-2014 models covering coolant leakage from the cylinder head that could contact hot engine components and cause fire. The 1.6L EcoBoost was also susceptible to head gasket failure and internal coolant leaks similar to the 1.5L and 2.0L EcoBoost engines in other Ford models. The engine was discontinued and replaced by the 2.0L EcoBoost in later Transit Connect models. The FordTransitConnectForum documents numerous cases of premature engine failure on 1.6L-equipped vans used in commercial service.
Common Symptoms
- Coolant loss without visible external leak
- Engine overheating warning
- White smoke from exhaust
- Sweet smell from engine bay
- Check engine light
- Engine rough running or misfires
- Smoke or fire from engine compartment (severe cases)
How to Fix
Check safercar.gov for Recall 14V309/14S11 coverage. Dealers replace coolant hose and associated components under recall. For post-recall coolant issues: cylinder head inspection and replacement of head gasket if internal coolant leak is confirmed. Extended warranty coverage varies - contact Ford Customer Relations. For commercial operators: consider replacing the 1.6L EcoBoost with the 2.5L i-VCT engine from later Transit Connect models if available.

Parts and tips from 560+ owners who fixed this issue
- NoteIf you have a 2013-2014 Transit Connect 1.6L EcoBoost, check safercar.gov immediately for recall 14V309 (coolant leak/fire risk). This is a safety recall - free repair at any Ford dealer regardless of mileage or current owner.
- TipThe 1.6L EcoBoost was discontinued after 2018 Transit Connect. If you have a pre-2018 model with coolant issues, ask your dealer about extended powertrain coverage. Ford has a history of extended warranty programs for EcoBoost coolant issues across all models.
- TipFor Transit Connect commercial operators: the 2.5L i-VCT (non-turbo) engine in later models is far more reliable for high-cycle stop-and-go commercial use than the 1.6L EcoBoost. If purchasing used, prioritize 2.5L models for fleet reliability.
The 2014-2016 Ford Transit Connect was included in one of Ford's largest-ever recalls affecting over 2 million vehicles for defective side door latches. NHTSA Campaign Number 16V643 covers approximately 112,225 Transit Connect vehicles manufactured between August 9, 2013 and February 1, 2016. The C1A door latch contains a pawl spring tab that is susceptible to cracking and fracture after repeated exposure to high temperatures and normal cycling. A broken spring tab may prevent the door from latching securely or cause a latched door to unlatch while driving. Consumer Reports reported on the massive Ford and Lincoln recall to fix door latches, and NHTSA documented the safety risk of doors opening while the vehicle is in motion. Ford also issued recall 20S30 and 23S36 for additional door latch concerns on overlapping model years.
Common Symptoms
- Door does not latch securely when closed
- Door ajar warning light stays on
- Door opens unexpectedly while driving
- Door requires extra force to close properly
- Clicking or unusual noise from door latch mechanism
- Interior dome light stays on indicating door is ajar
How to Fix
This is a safety recall - repairs are FREE at any Ford dealer regardless of mileage, ownership status, or warranty coverage. Contact Ford at 1-866-436-7332 or check safercar.gov with your VIN. Ford recall numbers: 16S30, 20S30, 23S36. NHTSA campaign numbers: 16V643, additional campaigns may apply. Dealers replace all affected door latches with improved design parts. If you purchased the vehicle used, the recall still applies - check immediately.

- NoteThis is a SAFETY RECALL - door could open while driving. Check safercar.gov with your VIN immediately. Repair is FREE at any Ford dealer regardless of mileage or whether you are the original owner. If you have a 2014-2016 Transit Connect, do not delay getting this recall performed.
- TipFord has issued multiple overlapping door latch recalls (16S30, 20S30, 23S36). Even if one recall was completed on your Transit Connect, check if additional recall campaigns apply. Some vehicles need multiple latch replacements across different recall numbers.
The 2017-2023 Ford Transit with the 2.0L EcoBlue diesel engine (available in some markets) and the 3.5L EcoBoost V6 experience fuel injector failures causing rough running, misfires, poor idle, reduced performance, and excessive smoke on cold start. Parkers UK documents an official Ford service action for Transit EcoBlue diesel injector failures traced to a quality issue with Continental-supplied injectors where an internal surface coating comes unstuck, blocking the injector. FordTransitUSAForum.com documents injector failure on 3.5L EcoBoost Transit models as well, where direct injection fuel deposits cause injector spray pattern degradation. RepairPal estimates individual injector replacement between $266 and $627 depending on Transit model, but multiple injectors often need replacement simultaneously, and contaminated fuel systems can cost significantly more.
Common Symptoms
- Rough running and engine misfires
- Poor idle quality
- Excessive blue or black smoke on cold start
- Reduced engine performance and power
- Check engine light with injector or misfire codes
- Engine stalls immediately after starting
- High fuel consumption
- Engine hesitation under acceleration
How to Fix
For Transit 3.5L EcoBoost: replace failed injectors ($100-200 per injector, 3-4 hours labor). Consider replacing all 6 injectors if the vehicle has over 100k miles - if one has failed, others are likely close behind. For EcoBlue diesel: Ford issued a service action for Continental injector failures - check with dealer for coverage. Use only Top Tier gasoline and change fuel filters per schedule. Professional fuel system cleaning every 50,000 miles can extend injector life.

- TipWhen replacing injectors on the 3.5L EcoBoost Transit, consider replacing all 6 at once if the vehicle has over 100k miles. Individual injectors are $100-200 each, and if one has failed from deposit buildup, the others are likely degraded too. It saves labor to do them all at once.
The 2019-2023 Ford Transit Connect equipped with the 8F35 8-speed automatic transmission experiences transmission shuddering, harsh engagements, slipping, and premature failure. Ford issued a Technical Service Bulletin for 2019-2021 Transit Connect vehicles built before December 20, 2021 with the 8F35 transmission addressing slipping and harsh engagement concerns. FordTransitUSAForum.com documents a 2019 Transit Connect XL 8F35 transmission failure at the 75,000 mile mark. Eng-Tips.com engineering forums discuss the inherent shudder issue in the 8F35 torque converter clutch. Earlier Transit Connect models with the 6F35 transmission also had recall campaigns (2013-2021 models). The transmission issues are exacerbated by commercial use patterns - frequent stops, loaded cargo, and city driving accelerate wear on the torque converter clutch and internal clutch packs.
Common Symptoms
- Shuddering during light acceleration at 25-45 mph
- Harsh or jerky gear shifts
- Delayed engagement from Park to Drive
- Transmission slipping under load
- Check engine light with transmission codes
- Transmission warning message on dashboard
- Grinding or whining noise from transmission
- Vehicle hesitates or surges at low speed
How to Fix
First step: check for TSB coverage and have the dealer perform a transmission fluid change with genuine Motorcraft Mercon ULV fluid and a TCM software recalibration. For 2019-2021 Transit Connect built before 12/20/2021, Ford TSB addresses 8F35 slipping. If shudder persists after fluid change and reprogram, the torque converter may need replacement ($800-1,500). Complete transmission replacement for internal failure runs $3,000-4,500. The powertrain warranty (5yr/60k miles) should cover this on newer vehicles.

Parts and tips from 780+ owners who fixed this issue
- TipFord issued a specific TSB for 2019-2021 Transit Connect 8F35 transmission shudder and slipping. Request the dealer check for this TSB by VIN. The fix involves a transmission fluid change with Mercon ULV and a TCM software update - often resolves the shudder at no cost under warranty.
- NoteDo NOT use any transmission fluid other than genuine Motorcraft Mercon ULV in the 8F35. Using the wrong fluid can cause permanent transmission damage. The 8F35 is very sensitive to fluid specification.
Ford Transit vans are well-known for water infiltration through the roof, particularly in medium-roof and high-roof configurations. Water intrudes through multiple paths: (1) factory roof plug holes (the 2015 roof has 16 plugged holes for optional roof rack and ancillary hardware), (2) roof rack mounting holes where Ford applies only primer circles without top-coat paint, (3) push-pin trim clips along the roof/wall junction, and (4) blocked windshield gutter channels that direct water into the engine bay instead of away from the vehicle. The rust issue is compounded by thin steel roofs and inadequate factory corrosion protection. The FordTransitUSAForum has extensive documentation of roof rust appearing within 3-5 years on vans operating in salt-belt states (Northeast, Midwest). For conversion van owners, water leaks can ruin expensive interior buildouts.
Common Symptoms
- Water inside cargo area after rain, especially at roof/wall junction
- Water in cab during heavy rain
- Rust bubbles or surface rust appearing on roof panel
- Water stains on headliner or cargo area ceiling
- Wet floor mats from water entering through gutter area
- Musty smell inside van
- Water in engine compartment during rain (blocked windshield gutters)
How to Fix
Preventive sealing: seal all roof plug holes with Dicor lap sealant or Eternabond RV roof tape immediately after purchase. Clean and seal all roof rack mounting holes with rust-inhibiting primer and clear coat. Inspect and clear windshield gutter drains annually. Apply rust-inhibiting undercoat to roof panel interior annually in salt-belt climates. For existing rust: wire brush, treat with Rust-Oleum Rust Reformer, apply self-etching primer, then paint. Dicor 501LSW or Eternabond tape are the most popular roof repair products among Transit owners.
What Owners Are Using
Parts and tips from 2,140+ owners who fixed this issue
- TipSeal ALL roof holes immediately when you take delivery of a new Transit - before water gets in. Use Dicor 501LSW lap sealant or Eternabond EternaBond-WS-4 tape. On 2015 models, you have 16 factory plug holes to address. This is widely considered the most important first mod for Transit van owners.
- TipClear your windshield gutter drains every spring - debris blocks them and water pours into the engine bay instead. The gutter runs along the bottom of the windshield and has drain holes at each corner fender. This is a 10-minute maintenance item that prevents expensive water damage.
- NoteIn Rust Belt states (NY, MA, PA, OH, MI, MN, WI, etc.), apply a rust inhibitor to the underside of the roof panel from inside the van before any buildout. Ford's factory rust protection on the roof is minimal. NH Rust Check, Fluid Film, or Rust-Oleum Automotive Rust Reformer are popular choices.
