Ford’s Documented Repair for the 2011–2015 F-150 EcoBoost Rattle
Table of Contents
That few-second rattle when your EcoBoost starts cold
A metallic rattle for a few seconds on a cold start is one of the best-documented faults on the 2011–2015 F-150 3.5L EcoBoost, and Ford put it in writing. TSB 18-2305 covers 2011–2015 F-150s with the 3.5L EcoBoost built on or before 29 May 2015 that make a rattle from the top front of the engine for 2–5 seconds after sitting six hours or more.
Find your situation:
- Noise only, no warning light: start with the symptom check below.
- Rattle plus a check engine light: a second Ford bulletin may apply.
- Holding a repair quote: go to the cost maths.
- Deciding whether to fix it at all: read what happens if you wait.
This is one entry in our guide to every documented F-150 problem by model year.
ℹ️ Safety Note: Cam phasers and the timing chain sit inside the engine, and a worn timing system can cause driveability problems and costly engine repairs. This article is for general understanding. Have the noise diagnosed by a qualified technician, and don’t attempt the repair from a bulletin: Ford states its bulletin procedures are for trained technicians, not do-it-yourselfers.
Is it the rattle Ford described, or a different problem?
Ford describes two separate conditions on these trucks, and they point to different bulletins.
The noise-only version: 2–5 seconds after 6+ hours sitting
Ford’s symptom is narrow: a ticking, tapping or rattle from the top front cover area on the first start after the truck has sat six hours or more, lasting 2–5 seconds. If that matches and no warning light is on, TSB 18-2305 is the bulletin to name.
Rattle plus a check engine light and P0016
Ford’s P0016 timing chain wear bulletin, TSB 17-0026 covers 2011–2014 F-150s with the 3.5L built on or before 10 October 2014. These trucks show a check engine light with code P0016, which Ford says may come from a worn primary timing chain. Other codes and driveability problems may also be present.
Noises neither bulletin describes
A rattle that lasts longer, happens with a warm engine, or comes from somewhere else doesn’t match either bulletin’s description.
✅ Do This: Before approving a timing job, ask the shop two questions. Does the noise match the TSB 18-2305 symptom? Are any codes stored, such as P0016?
Which 2011–2015 F-150s Ford’s bulletins actually cover
Coverage under each bulletin depends on three things: model year, build date and symptom.
| Model Year | Built On or Before | Bulletin | Applies To | Ford Labour Time |
|---|---|---|---|---|
| 2011–2014 | 29 May 2015 | TSB 18-2305 | Cold-start rattle | 9.2 hrs |
| 2015 | 29 May 2015 | TSB 18-2305 | Cold-start rattle | 9.0 hrs |
| 2011–2014 | 10 Oct 2014 | TSB 17-0026 | Check engine light with P0016 | 8.9 hrs |
Source: Ford TSB 18-2305 (24 Oct 2018) and TSB 17-0026 (8 Mar 2017), as published on NHTSA. F-150 with 3.5L EcoBoost only.
2011–2014 trucks
These trucks can fall under either bulletin, depending on whether the problem is noise-only or code-driven.
2015 trucks: the 29-May-2015 cutoff
A 2015 built after 29 May 2015 is outside TSB 18-2305. Ford’s procedure starts with a build-date check, so ask the dealer to confirm yours by VIN.
2016 and 2017+ trucks
TSB 18-2305 names 2011–2015 F-150s only. Owners of later trucks should see how 3.5L EcoBoost problems differ by generation and our guide to the cold-start phaser rattle on later F-150s.
What TSB 18-2305 tells Ford dealers to replace
Ford’s TSB 18-2305 directs dealers to replace all four variable camshaft timing (VCT) units, the cam phasers, plus the primary timing chain on qualifying 2011–2015 F-150s.
📋 On the Record: Ford’s cold-start noise bulletin, TSB 18-2305, dated 24 October 2018, supersedes TSB 16-0027. It covers 2011–2015 F-150s with the 3.5L EcoBoost built on or before 29 May 2015. No superseding bulletin was found; status checked 17 September 2026.
It’s the phasers and the chain, not just the chain
“Timing chain rattle” is the owner’s name for this fault. Ford’s fix goes further than the chain: it replaces all four phasers too.
🔍 Why It Happens: The phasers adjust cam timing using oil pressure. The widely described explanation from engine rebuilders is that a locking pin inside each phaser wears. Oil drains out overnight, so on startup the internal parts knock until oil pressure builds. Ford’s bulletin itself doesn’t describe this mechanism.
Why your quote may only list a “tensioner kit”
The bulletin’s parts list names one Timing Chain Tensioner Kit, not separate phasers and a chain. Ford parts sellers list that kit as containing the phasers and chain.
A TSB is a repair instruction, not a recall
A TSB tells dealers how to fix a condition. It doesn’t make the repair free.
Will Ford pay for the rattle repair in 2026?
For almost every 2011–2015 truck, the factory warranty that could have covered this has run out.
What “eligible under warranty” in the TSB really means
TSB 18-2305 lists the repair as eligible under Ford’s New Vehicle Limited Warranty coverage. It also states that a bulletin doesn’t change warranty limits. The bulletin only applies within your truck’s existing coverage; it adds none.
Why 2011–2015 powertrain coverage has run out
Ford’s powertrain warranty terms run 5 years or 60,000 miles from the warranty start date, whichever comes first. Check the original warranty guide for these model years for your truck’s exact terms. TSB 17-0026 also lists emissions warranty eligibility, which has its own term.
Recall and program check for your VIN
As of 17 September 2026, our search found no safety recall for this condition on 2011–2015 F-150s. NHTSA complaint records show 2013 owners with a phaser diagnosis being told their VIN wasn’t under recall.
✅ Do This: Enter your VIN on NHTSA’s recall lookup, then ask a Ford dealer to check your warranty start date. Any open campaign is repaired free.
What the phaser and timing chain job costs out of warranty
Most of the cost is labour, and Ford publishes the hours.
💵 On these numbers: Costs shown are typical ranges, not quotes. Labour rates vary sharply by region and between dealer and independent shops, and parts pricing moves. Use these to judge whether a quote is in the right neighbourhood, not to predict your invoice.
Ford’s labour time: 9.2 or 9.0 hours
The replacement is rated at 9.2 hours for 2011–2014 trucks and 9.0 hours for 2015.
| Job | Applies To | Ford Hours | Labour at $120–$159/hr | What It Includes |
|---|---|---|---|---|
| TSB 18-2305 | 2011–2014 | 9.2 | $1,104–$1,463 | Labour only |
| TSB 18-2305 | 2015 | 9.0 | $1,080–$1,431 | Labour only |
| TSB 17-0026 | 2011–2014 | 8.9 | $1,068–$1,415 | Labour only |
Rate band: the 2025 PartsTech Report, via AAA, found almost half of US shops charge $120–$159 per hour. Excludes parts, fluids, tax and diagnostic fees.
Parts: what the kit includes
Parts come on top of labour: the kit, gaskets, sealant, coolant and oil.
Dealer vs independent quote maths
💵 What It Costs: Divide the labour on your quote by Ford’s hours to find the shop’s effective rate. AAA reports rates range from under $100 to over $200 per hour by location. Compare yours with our Repair Cost Estimator.
What happens if you keep driving with the rattle
The cold-start noise itself is short, but a worn timing system can lead to more problems.
When the rattle becomes a P0016 and driveability problem
Ford’s TSB 17-0026 ties code P0016, other codes, and driveability problems to a worn primary timing chain on 2011–2014 trucks. Neither bulletin says the cold-start noise turns into that condition. Both involve the same primary chain.
⚠️ Watch Out: A check engine light appearing with the rattle, or rough running, changes this from a noise to a diagnosis. Book an inspection rather than waiting.
Fixing vs selling a high-mileage 2011–2015 truck
Weigh the full quote against the truck’s value and your plans for it. Our Fix-or-Sell Calculator runs the numbers.
✅ Do This: Ask the shop to read stored codes and check the VCT_INT_ACT1 value that TSB 17-0026 uses. Then ask for a quote built on Ford’s labour hours for the matching bulletin.
Frequently asked questions about the EcoBoost cold-start rattle
1. Is the EcoBoost cold start rattle covered by warranty?
TSB 18-2305 lists New Vehicle Limited Warranty eligibility, but powertrain coverage lasts 5 years or 60,000 miles, so it has expired on nearly all 2011–2015 trucks. Confirm your warranty start date with a Ford dealer.
2. What causes the 3.5 EcoBoost startup rattle?
Ford’s TSB 18-2305 repair replaces all four cam phasers and the primary timing chain on qualifying 2011–2015 F-150 3.5L EcoBoost trucks.
3. Is the EcoBoost rattle the timing chain or cam phasers?
Ford’s cold-start rattle fix replaces both. A check engine light with P0016 points to Ford’s separate timing chain wear bulletin, TSB 17-0026.
4. Is there a recall for the 2011–2014 EcoBoost timing chain?
Our 17 September 2026 search found no safety recall for this timing chain condition on 2011–2015 F-150s. Run your VIN on NHTSA’s recall lookup.
5. How much does the TSB 18-2305 repair cost?
TSB 18-2305 labour is 9.2 hours (2011–2014) or 9.0 hours (2015), about $1,080–$1,463 at $120–$159 per hour, before parts. Get a written quote.
6.Can I keep driving with the cold start rattle?
The cold start rattle alone lasts seconds, but a check engine light or rough running means the timing system needs diagnosis soon. Book an inspection.
7. Does TSB 18-2305 cover 2015 F-150s?
Yes. TSB 18-2305 covers 2015 F-150 3.5L EcoBoost trucks built on or before 29 May 2015. Later 2015 builds fall outside it.
8. What is Ford TSB 17-0026?
TSB 17-0026 covers 2011–2014 F-150 3.5L trucks built by 10 October 2014 showing code P0016, possibly caused by a worn primary timing chain.
9. How do I find my F-150 build date for the TSB?
Ford’s TSB procedure starts with a build-date check, so a Ford dealer can confirm your F-150’s build date from your VIN.
10. Why does my EcoBoost rattle quote list a tensioner kit?
TSB 18-2305’s parts list names a single Timing Chain Tensioner Kit, not separate phasers and a chain. Ask the shop to itemize what the kit contains.
What to do next with a rattling 2011–2015 EcoBoost
Confirm your noise matches Ford’s 2–5 second cold-start description, and check for stored codes. Have a dealer confirm your build date against the 29 May 2015 and 10 October 2014 cutoffs. Then get a written quote tied to the matching bulletin’s labour hours, and compare its rate against the ranges above.
