Passenger and driver seats in my 2000 GMC Sonoma have seat positioning controls and locking mechanisims that do not always lock properly and/or get jammed up and have broken. A friend was sitting in the passenger seat and it failed to lock into place to keep it from sliding forward. I adjusted the bolts that fasten the seat to the floor of the vehicle to help 'realign' the seat frame so that the mechanism that keeps the seat from siding front and back would keep the seat locked into position once the seating distance is set. Also, the reclining handle on the passenger side broke off, not allowing for seat back support angle adjustment on the passenger side. The driver's side seat back support adjustment lever often 'sticks' or 'locks' into position....not allowing for seat back rest adjustment. …

2000 Sonoma · Feb 2016

The driver's seat adjust failed. No pressure--could be put on the seat without it moving to the full back position. The dealer initially replaced this in mar 05 after me and dealer speaking with GMC customer satisfaction. GMC reimbursed me for costs. 15 months [!!] later, it failed again. The dealer had only seen this issue twice, both times with my car. GMC initially declined to pay for the repair. Then, after discussion with me, they offered to pay for it with me understanding that they had no liability and would not pay for any future repairs or would offer me $500 certificate discount on a new GMC truck. When I mentioned the safety issue potential, they wanted me to understand that if I accepted the money, I would have no standing in future problems of the same nature. I decline. I am concerned about the safety potential of this. They have twice corrected the symptoms. …

On our 1998 GMC Sonoma we have replaced the windshield wiper motor and board. The wipers still have a ghost in them and delay does not work most of the time and high speed when on low speed, erratic behavior on wipers. Won't turn on or off on occasion. Was there a recall on also on the passenger seat? The lever broke right off the first time we used it. Cheaply built handles. Please send me a list of recalls on this vehicle please for our own safety as this vehicle is driven daily on open highways.
