problem #2

Terraza 6-cyl

  • Automatic transmission
  • 29,000 miles


: the contact stated the headlights flickered when the vehicle was driven 0-60 mph. When the vehicle was taken to the sales/service dealer, the problem could not be recreated. The voltage regulator was replaced, but the problem continued. The lights failed to remain bright enough to see well at night. The computer programming was reflashed. The vehicle also had an ongoing issue with the starter, sliding door opening by itself when the vehicle was parked or while idling in park. On one occasion, the child passenger fell out of the vehicle when the door opened. There were no injuries sustained. There was a problem with the steering which resulted in the contact side swiping a mailbox post on the side of the road. At a later date when the vehicle was parked in the garage, the vehicle caught on fire. There were no reports taken by the police or fire department. The manufacturer was notified and the service dealer towed the vehicle back to the dealership.

Terraza 6-cyl

The contact stated while driving all of the lights dimmed. The fan motor lost power. This happened eight times on a ten mile drive. The vehicle has been to the dealership, and they replaced multiple components, but the problem got worse. The engineers for the manufacturer sent the service department 40 tests to run on the vehicle to diagnose the problem, but nothing was found. The zone manager for the manufacturer stated they were aware of the problem, but did not deem it a safety hazard. The service manager at the dealership test drove another vehicle on the lot and found it had the same defect. In addition, upon purchase, the rear door had to be adjusted. The contact was unable to shut the door, it was too loose. Also, the vehicle had a problem with the leveling system, twice when trying to get into the vehicle it was completely dead. They could not unlock the vehicle, and had to get it towed. The dealership stated a switch that was not deactivating, causing the battery to die. This defect was repaired.
