Why is my Hyundai Santa fe hard to start and then it doesn't want to accelerate over 20 mph?

If your Hyundai Santa Fe is hard to start and struggles to accelerate over 20 mph, it could be due to several issues, such as a failing fuel pump, clogged fuel filter, or a malfunctioning sensor like the mass airflow sensor. Additionally, problems with the ignition system, such as worn spark plugs or ignition coils, could contribute to these symptoms. It's advisable to have the vehicle diagnosed by a professional to pinpoint the exact cause and ensure proper repairs are made.
