Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Started to hear a clunking noise. Then vehicle would not back up. Checked transmission fluid and found low. Added fluid (1 quart) and was able to move, but since then the vehicle will not stay in park. It creeps ahead or back on uneven ground several feet. Called to make an appointment and dropped vehicle off to dealer whom I bought it. They had it for a day and called to have me pick it up. They had a bill for me and told me nothing was wrong with the vehicle. I told them there was something wrong and the manager brought the mechanic out and he confirmed that there was nothing wrong. …”
