2002 Envoy 1 time intermittant issues

02EnvoySLT · May 9, 2002

Well, 7K on the Envoy SLT and during that time I've experience multiple 1 time intermittant problems. Here they are:

1) Radio was on but no sound from speakers, no beeps from speakers for belts and no sound from On Star. Solution: Turn off car and wait and restart. 1 Time Issue

2) Hit my remote (#2) to open truck and the mirrors didn't adjust to position. Solution: Hit the seat position on the door. 1 Time Issue

3) Wife called from cell sayin ABS light came on while at a stoplight. Said when she tried to pull away on green light it was hard to accelerate so she pulled over and noticed the light. She called me and I told her to turn of the car, wait a few minutes and start it up. Solution: Restart. 1 Time Issue - NOTE: Autotap Scan Tool showed no pending codes or set codes, etc when she got home.

4) Pull away and notice the speedo climb rapidly. I was probably doing 40mph but the speedo was showing 70mph! Yeah, it's the only time I could do 0-60mph in less then 5 sec in the Envoy. Solution: Restart. 1 Time Issue

Long term Issues:

1) Autotap Scantool Vehicle Mileage parameters shows that my PCM's Odometer has 38K on it when the Dash display shows 7K. The PCM odometer has been incrementing at a rate of 5.5 times faster. Hmmm, doesn't do this for any other cars I've scanned in the past. Strange.

2) Cam phaser solinoid above thermostat housing on passenger side at engine looks like the housing is slowly leaking fluid. Will keep and eye on it. Anyone else have a wet spot there?

3) When driving behind the Envoy, my eyes tell me that it tends to lean to the right. Is the air ride system that uneven?

Other then the above, the thing is excellent, fast for a loaded tank and civil and smooth! RPM only deviates 5-10 rpm at idle between 600 and 610.

Thanks,

John
