“I purchased my 2009 vw EOS from a dealeriship as-is and I have had to replace the maf sensor, throttlebody had to be serviced with in the first year of owning.

While traveling with my two young sons for their spring break, my car completely failed (while in-motion), putting both my life and the lives of my two children in harm's way. The time and resources spent getting my car towed to the mechanic, emotional trauma/stress, and loss in productivity has been a blow for my family- not to mention the cost to repair (which I have yet to receive the invoice). …”
NHTSA complaint #11078965, filed 2018-03, 111,000 miles“My wife was turning into a parking lot when the engine suddenly made a noise and lost forward power. She was stuck in the middle of an intersection and could have been killed! We spoke to our mechanic and he diagnosed the problem as a failed timing chain tensioner. This caused the engine valves to impact the pistons and caused catastrophic engine damage. We paid $2706.25 to buy a used engine and $1500 in labor for the installation. Our mechanic said this is very common with this engine and that he see this happen with engines that have low mileage. Our had 80125 when this happened.”
