Filed Nov 19, 2025 · Brakes, Electrical · MI

Was Delivered. Took for a test drive. Stalled at stop sign. Restarted went down the road stalled and slammed into park. Contacted company was told to take to local GMC/Chevy, (said they did a bunch of research and this part should work) basically guessing had my vehicle for 9 months replaced some sensor. Had my boyfriend Drove to red light, not even half a block, stall (stable track sensor) but lost all electric but v8 still ran took to another ( had towed) to another local shop they had for 4+ months couldn't figure out said it was running 18+ codes and would cost too much to go through. Contacted company the gentleman politely laughed and said ur kidding me right it's been years I tried to explain how long it was taking due to both repairs company had it over a year n half. No sympathy he knew exactly what he sold.

I had bought the 08 Tahoe hybrid. The day it was delivered, it stalled I called the dealership out of Minnesota and was told oh it could be this it could be that went to two local shops and a private shop all had different specifications as to what was wrong with the car due to so many codes being thrown out. You would try to take off from a stop sign or a red light car would completely lose all power, almost had multiple people slam into me because it always happened, caused so much anxiety because my only wheels to get my children around. Once again was told to take it in GM had it for over a year and could not figure the issue out. I was told by the dealer multiple times it was not their issue and they knew the position I was in an said it was inspected but refused to send me the paperwork.

I purchased my tahoe from the dealer brand new and always took it to get serviced at the same dealer. In 2015 I took it in for a check engine light and they said there was a misfire and they replaced the camshaft and machined the heads stating that the valves were leaking. Repairs cost nearly $3000. This year 2018 in march the engine light came on again. The dealer stated that there was a misfire in a cylinder the same cylinder that was mifiring 3 years prior. They said a roller on the rocker disintergrated and repairs would cost close to $6000 this is not due to anything I did the vehicle does even have 100,000 miles on it. No harsh driving or anything like that. I believe this is a manufacturing issue. Not a safety issue but I think it is a manufacturing defect.
