2004 GMC Envoy Owner Comments

problem #1

Nov 162004

Envoy 4WD 6-cyl

  • Automatic transmission
  • 2,000 miles


1. engine will shut off when making a hard turn: After stopped at a stop sign, I was trying to make a hard turn (steering wheel reached the maximum turning angle) when the engine suddenly shut off itself. It happened three times either tuning left or right (today), but always after stopping and with a hard turning angle. It is such a huge safety defect with all the cars infront and behind you. No repair action has been taken. The problem may be reproduced. 2. turning signals not working after emergency lights used: It happened two times. Turning signal lights (left or right) will not work correctly after the emergency lights were in use; instead both left and right turning lights will flash at the same time. It can be reproduced. No repair action taken yet. 3. difficult turning at a hard turn with 4-wheel-drive is on: It is almost impossible to make a hard turn when the 4-whell-drive is on. It happens every time. No repair action taken yet.
