Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“1 - there is up to a two second delay when quick acceleration is required. At times it feels as if the engine completely stalled. 2 - the vehicle often will not downshift to slow the vehicle on a hill. I could be in 5th gear at around only 1800 RPM, and when I downshift twice, it will not go to 3rd. I often have to downshift up to 6 times for it to respond and switch to third. I need to take my eyes off the road to constantly check if I'm in the gear I select. 3 - the parking/emergency break will not hold the fully loaded vehicle on a hill. …”
