A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

I was stopped at a red light and was rear ended by a car going 40. The car started on fire in the rear of the vehicle and burned pretty bad. I have to get a new car due to the significant damage resulting from the fire, I'm just happy my kids weren't with me at the time. I have herniated and bulging discs in my cervical and lumbar, which were found by mri. Not sure what happened with this car but thought it important to let the general public know about it.

After spending 38 minutes writing about problems with my auto your defective program erased all my narrative. I suggest you hire one of the several thousand capable people who would like to work to replace the incompetent bungler who created this abomination.
