Power train

2 reports1 related recall
“While attempting to accelerate my car hesitates and slows down to about 5 miles an hour. This mostly happens in the morning, but does happen in the afternoon while attempting to accelerate to pass. This issue has almost caused me to get in accidents on several occasions. I first noticed this issue when I first purchased the vehicle. I took it in and it was kept at the dealership for a week or so. When it was returned the dealer told me they couldn’t find a problem. I later took the car to another dealer and was the fuel injectors need to be cleaned but this did not fix the problem.”
