Timing chains are meant to last the life of an engine, yet owner complaints and mechanic reports show plenty of exceptions. Costs and mileages vary widely, and a few entries rest on reliability rankings or mechanic opinion rather than repair data. Here are eleven vehicles where the chain has drawn attention.

1. Volkswagen Tiguan: Tensioner Trouble
The Volkswagen Tiguan’s 2011 model shows a timing chain tensioner defect that causes engine damage, averaging $4,000 to fix at 90,000 miles, according to the CarComplaints Tiguan page. The model has 512 complaints on file.
A failed tensioner can let the chain slip and harm the engine, so unusual rattles on startup deserve a prompt inspection. Buyers of used Tiguans should ask whether the tensioner has ever been replaced. Checking by VIN for open recalls at NHTSA costs nothing and takes a minute.
2. Cadillac CTS: Seven Failures, One Bill
The 2009 Cadillac CTS has seven reported timing chain failures, averaging $3,400 to fix at about 95,050 miles, per the CarComplaints CTS records. That figure is the cost behind the gallery headline.
Seven reports is a small sample, so the number reads best as a sign of what a failure can cost rather than how common it is. Service records are worth requesting before buying an older CTS. A pre-purchase inspection by an independent mechanic is cheap next to a repair of that size.
3. Buick Enclave: A Top-Three Buick Problem
The timing chain on the 2010 Buick Enclave ranks among the brand’s top problems, averaging $3,000 to fix at 105,000 miles. The CarComplaints Buick listing shows 665 complaints for the Enclave overall.
Chain work at six-figure mileage is a repair that many owners of big crossovers eventually face. A buyer should ask whether it has been done and look for receipts if it has. Records of oil changes matter here, since chain wear is often linked to how well an engine was maintained.
4. Chevrolet Malibu: Broke at 117,000 Miles
The 2011 Chevrolet Malibu has nine timing chain breakage complaints, averaging $2,660 to fix at about 121,100 miles. One owner quoted on the CarComplaints Malibu page reported that the chain broke at 117,000 miles.
A broken chain usually stops the engine without warning, which makes a pre-purchase inspection and a look at maintenance history especially useful on a Malibu from this period. Walking away from a car with no paperwork at all is a fair option.
5. Mazda CX-7: Stretched on a CX-7
Twenty complaints on the 2007 Mazda CX-7 describe a stretched timing chain, averaging $2,680 to fix at 80,000 miles. Owners on the CarComplaints CX-7 page also link the problem to the variable valve timing system.
Chain stretch tends to build gradually, so noises or warning lights are worth chasing early. Anyone considering an older CX-7 should have a mechanic look at the timing components. Used-car shoppers should also ask whether any earlier repair addressed the issue.
6. Chevrolet Camaro: Premature Chain Wear
The 2010 Chevrolet Camaro is rated worst for premature timing chain wear, costing about $1,900 at 80,000 miles. The CarComplaints Camaro page lists 532 complaints on file for the Camaro.
The cost is lower than on some rivals in this gallery, but the mileage is early. Asking a seller about any timing-related repair is a reasonable step for anyone shopping a fifth-generation Camaro. A cold-start listen for rattling or whining can reveal a lot before a purchase is made.
7. Mazda CX-90: Low Reliability Score
Consumer Reports gives the Mazda CX-90 a predicted-reliability score of 23, citing premature timing chain failure among its engine problems, as Guide Auto rankings reports in its list of least reliable 2026 models.
A predicted score is a forecast, not a count of failures. Shoppers weighing a CX-90 can check warranty terms, confirm recall status by VIN at NHTSA, and ask a dealer about any known timing issues. Warranty paperwork is worth reading closely before any decision.
8. Chevrolet Traverse: A Mechanic’s Doubt
A mechanic quoted in an AOL mechanic feature flags transmission problems and timing chain issues on the Chevrolet Traverse as reasons to doubt its long-term lifespan.
This is one professional’s opinion without repair costs attached, so it works as a prompt for questions instead of a verdict. Service history and a pre-purchase inspection can help separate good examples from poor ones. Test-driving for hesitation or rough running is another easy screen.
9. Mercedes-Benz C-Class: Worn Sprocket Teeth
On 2005 to 2014 Mercedes-Benz models with the M272 or M273 V6, including the C-Class, worn sprocket teeth can make the engine lose proper timing, according to MotorBiscuit timing chain list.
Because the issue is tied to an engine family, buyers should confirm which engine a given car has. A specialist inspection is wise, as timing problems can lead to serious engine damage if ignored. Sellers should be able to show what maintenance has been done on the engine.
10. Mini Cooper: Mini Cooper Mechanic Warnings
Mechanics cited in a Truth About Cars list flag timing-chain issues and oil leaks on Mini Coopers, particularly models from the 2000s and early 2010s.
The report offers no repair figures, so shoppers should treat it as a checklist item. Looking for oil seepage and listening for chain noise during a cold start are practical ways to screen an older Mini. Reading the previous owner’s receipts can reveal whether any chain work has been done.
11. Cadillac SRX: Chain Trouble in Canada
The 2010 Cadillac SRX ranked seventh in a Guide Auto list of vehicles with major engine problems, which included timing chain trouble at around 210,000 kilometres, according to the Guide Auto engine gallery.
The same list also flagged electrics, the catalytic converter and injectors, making a thorough inspection of an older SRX worthwhile. Negotiating around an unknown engine history is reasonable for any older luxury vehicle, and a documented repair history is a point in a car’s favor.
