My wife and I were shopping for an SUV because she grew tired of minivans. She saw a traverse and fell in love. She likes being up off the pavement higher than the van and likes the third row seat. She also likes how the seats in the rear and middle fold forward flat for hauling large items. Me being mechanically minded had questions about the traverse's 3.6L engine. I found some reports of the timing chain jumping out of time. I researched and talked to 3 or 4 mechanics. Two who work for a Chevrolet dealer. They told me that changing the oil regularly (about 4 to 5k miles on full synthetic which is what the manual calls for) will keep the chain running smooth. Fuel mileage is good at about 22 on the interstate. Ride is comfortable.
This car has been the worst vehicle I've ever owned. I've had to have it towed multiple times because of engine issues, fluid leaking etc.. Currently the vehicle is being worked on to repair the same engine issues it had a year and a half ago. There are MULTIPLE known issues with the 2009 Traverse with there being a GM warranty in place to cover those issues even though the car is so old. Luckily I got the extended warranty when I purchased the vehicle and that has covered non known issues but I've still had to pay a $100 deductible each time. Est. the warranty company has paid more than $10k in repairs on this car since 2015. The 09 GMC Acadia is the sister of the Traverse and has the same issues. I would avoid this car like the plague.
I have very happy with my Chevy Traverse. Its very spacious and comfortable for both drivers and passengers. Besides getting used to gas mileage, i am definitely pleases and would recommend this crossover vehicle to anyone.
