Complaint numbers: 10967663, 10967668, 10967666 and 10967670, were all filed less than 24 hours ago. Attached is more supporting documentation on the "7" zenith drivetrain failures and lack of support from zenith despite our request for service and being under warranty. We have had to purchase other conventional fuel shuttles in order to run our operation.

- San Diego, CA, USA

The coupler between the motor and the transmission has repeatedly failed; also, the A/C continually leaks as the high pressure hose from condensor to compressor is too short. Attached is the purchase invoices from the most recent two zenith shuttles and other supporting documents on the zenith drivetrain issues which are also supported in the other two filed complaints of #: 10967663, 66 and 68 zenith has refused to give us support. We are a commercial operator with courtesy passenger shuttles for movement of people to and from our parking lot and to the san diego airport. We are a ground transportation off airport parking operator. The shuttles have broken down to and from base during operation, the route is 9 miles round trip. We average 150 miles per day in a shuttle. We are in street traffic with stop lights and high congestion due to the roadways at the airport have high use. We operate 24/7 and have been in business since 1991 and we have never had broken drivetrains or axles in our shuttles. We have videos of the floppy coupler that demonstrates the ongoing issues of this part and the impact that a floppy coupler has on the splines of the motor and gear box. The video files are too big to upload. This complaint will be 3 of 3 as we have 3 shuttles by zenith that were all purchased in 2015. Here is a video link from zenith on May 5, 2016 on the coupler: Https://www.dropbox.com/S/1ktuvg1Q7whfnu1/old_vs_new_coupler%20video%20by%20zenith%205-2016.mov?dl=0 link permissions for 'old_vs_new_coupler video by zenith 5-2016.mov'
