In short
- Some popular powertrains have well-known problems: knowing them changes how you inspect a car.
- Ford's PowerShift dual-clutch (Fiesta, Focus) is known for shudder and failures.
- Early Nissan CVTs and some Hyundai and Kia Theta II engines have well-documented issues.
- GM V8s with cylinder deactivation and Ford's 3.5 EcoBoost have their own weak points.
- A known problem isn't a reason to refuse a car: it's a reason to check records, recalls and price.
Ford PowerShift (Fiesta and Focus)
The PowerShift dual-clutch transmission in Fiesta (2011–2016) and Focus (2012–2016) models is known for shudder, slipping and hesitation, and was the subject of extended warranties and litigation.
- On the test drive, pull away gently several times and drive in slow traffic.
- Ask for records of clutch or control module replacements.
Nissan CVTs
Several Nissan models of the 2010s with CVT transmissions (Altima, Sentra, Rogue, Versa and others) are known for whining, shuddering and loss of power, sometimes covered by extended warranties.
- Listen for a whine that rises with speed.
- Ask for CVT fluid service records and any software updates or replacements.
Hyundai and Kia Theta II engines
Some 2.4 and 2.0 turbo Theta II engines fitted to models such as the Sonata, Santa Fe, Optima and Sorento in the 2010s were recalled for bearing failure risks, with extended engine warranties.
- Check open recalls with the VIN. See VIN and recalls.
- Listen for knocking, and ask whether the knock sensor software update was installed.
GM AFM/DFM V8s and Ford 3.5 EcoBoost
- GM 5.3 and 6.2 V8s with cylinder deactivation (Silverado, Sierra, Tahoe and others): lifter failures causing ticking and misfires.
- Ford 3.5 EcoBoost (F-150 and others): cam phaser rattle at cold start, and timing chain wear on earlier engines.
How to use this list
Many owners of these cars have no trouble, especially when maintenance was done on time. Ask for the records that prove the weak point was addressed; otherwise, include the repair cost in your offer, or consider whether a service contract is worth it.
The Carvizia report identifies the listing's exact engine and transmission and lists their common problems with repair costs and the model's NHTSA recalls.

About usFrequently asked questions
Should I avoid every car with a CVT?
No. CVTs vary a lot by manufacturer and generation. Check the exact transmission and its service history.
How do I know if a recall or extended warranty applies?
Check the VIN on nhtsa.gov for recalls, and ask a franchised dealer about any extended coverage for that VIN.
How do I know the exact engine of a listing?
The VIN's 8th character often encodes the engine. Carvizia identifies the powertrain from the listing details.
