Vehicle Speed Control problem #1

Experiencing reduced speed, rattling noise, check engine light, power steering light on. Chevy app shows throttle control system and antilock break system error messages. Took to chev dealership. Advised it was fuel injector (1 /4 was burned out). Had all 4 replaced ($3000). Picked up car on a Friday, vehicle was having the same issues next day Saturday. Took it back on Monday, it is now Wednesday and they’re saying it’s the turbo charger now (another $3000). Mechanic couldn’t figure out what the issue was so it took 3 days for him to now say it’s the turbo charger. I think it was the turbo charger from the get go! what’s the purpose of the diagnostics ($250)? isn’t it to pinpointed the issue? 1st day, took him 4 hours to say it was the fuel injector. 2nd time around it took 3 days. I kept showing them and telling them it’s the throttle control system! they’re trying to rip me off! mechanic is saying he’s been test driving it and no issues. I took a photo of my mileage before I handed them my car and it was 79,190. The mileage today says 79,191. How and where is he test driving it if it’s only been 1 mile? reverse and forward ? they’re lying.

Vehicle Speed Control problem #2

Check engine light is on. Took to o'reilly and had them put their tester on it to get the codes. Codes show p0700 and p1467. My cruise control and auto start will not work. My mechanic said this is an issue that should be fixed free of charge but no recalls show for my vehicle.

Vehicle Speed Control problem #3

Engine power reduced came on after I was driving from a patient’s home. My car started driving very rough. I had to pull over because I was in danger of being hit from behind. I took my car to a mechanic and was diagnosed with the code dtc p2714. I looked online and there are a lot of people having this issue and being put in dangerous situations when we drive. Chevy knows about the issue and has not issued any recalls. Unfortunately for me my vehicle is past the limited warranty so now I have to save up money to get my transmission serviced. I’m never buying american again. I could’ve been really hurt when my engine cut off.

Vehicle Speed Control problem #4

3 times in the last year while we were driving the acceleration wen very high like from 50 to all of a sudden went up to about 80. I had to stand on the brake and try to pull over. Still accelerating I put it in park and shut it off. When you restart it it drive fine again. This has happened three times and the dealership says they can't find a problem. We are stuck driving a death trap. Please help. They wanna charge diagnosis everything I take it in. Then they say they can't find nothing. Now I am finding others that have had same issue and dealership says there is no problem. This has got to be destroying the engine reving at such high speeds.
