Excessive engine noise may be noted after a cold start. If the engine oil level is correct this type of noise is commonly caused by faulty timing chain tensioners. Our technicians tell us that revised chain tensioners are available to correct this issue.

Model years 2007-2012 of the Hyundai Veracruz using the 6-speed automatic transmission have been known to produce hard shifting and transmission slippage between gears, thought the check engine light may not illuminate. This is most noticeable when the transmission is hot, but can happen at any time. Note, this transmission is designed to be ‘sealed for life’ meaning the transmission fluid is never meant to be changed.

As many drivers and owners have learned, the issues are caused by problematic software for the transmission or mechanical failures associated with the transmission valve body or shift solenoids.

In order to restore transmission performance while shifting, the manufacturer of the transmission has issued several software updates that should correct the shifting issues. If hard shifts and slippage still exist after the software updates are completed, the transmission must be removed, disassembled, inspected and repaired.

 

Some technicians have advised replacing transmission fluid at normal intervals, but the manufacturer guidance is to use the original transmission fluid for the entire service life of the vehicle.
