Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Vehicle started to stutter and having a loud knock from engine after sitting for 6 hours on a normal night, normal driving conditions, maintenance kept up including recent oil change... Started to drive the vehicle and it had loud pinging and knocking became louder when I tried to accelerate once getting on the highway and the vehicle started to stutter. I had no check engine lights, no oil lights, nothing. …”
NHTSA complaint #11115259, filed 2018-08, 43,000 miles“While driving my vehicle, it started misfiring, throwing up a flashing check engine light, and it was rough to keep it running. Upon towing it to the dealership and having it investigated for the root cause, it was determined that the valve springs on a cylinder are failing. This issue is identical to the issues that are occurring in safety recall j02, which affects 2013 models.”
NHTSA complaint #11205250, filed 2019-05, 120,000 miles“I was driving 80 mph in the inner lane of a multi lane highway. Out of no where with no warning lights or sounds the car just lost all power, the steering felt like it locked and the car fell on it's face. I was almost hit by two different cars trying to get over to the shoulder and there was white smoke pouring out of the exhaust making cars behind me swerve because they couldn't see. Had it towed to the Toyota dealership and they told me that basically the engine blew and that they have seen this on other Scion model years and those are recalled but mine isn't recalled”
