Open the full vehicle complaint log (all categories)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.
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.
