The gas tank was only getting 10 gallons of gas and not 16 gallons like it was suppose to. We ended up running out of gas on a road trip with our two young daughters in the middle of the night on I-75. The gas tank said you had 100 miles to go before empty and then 3 miles later it would drop to 0 and you were running out of gas. This car was used in street racing which was late devulged to us after we found out that at 20,000 miles a whole new engine was put in without our knowledge when we purchased the vehicle . We took it to the dealer and they put a new fuel assembly unit in it. It fixed the problem a little but never fully. Now, 2 days ago my husband with my youngest daughter ran out of gas again on US-19 and I had to leave work to go get them and gas. Next on the 57 things wrong with this car… 5 days after purchase it had 22 engine warning. Took it back and they replaced the 4th coil and the 4th injector and spark plug. About 3 days later my husband came flying into his work, ran by me grabbing a fire extinguisher and ran to the car and started shooting it at the car, the car had caught on fire and the 4th injector was spewing gas. They had pinched an oring while installing the injector and never put the clips back on the injector rail to keep them in place. My husband could have been killed easily. The dealership never took ownership for it and blamed it on the dealership that sold us this the car. Every time we turn around it’s something else. The month of December we only had the car 6 days. It was in the shop 3 different. Times and everytime we got it back it wasn’t fixed. We bought this car in September and it had had 52 engine lights, over 10,000 in parts and labor to fix. Four rentals cars a new battery list goes on. We have tried numerous times to ask the dealership to make this right and their answer is for us to sell them the car back less our 20,000 deposit and buy a whole new car from them. That’s the solution we were given

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Ford Mustang Gt350r verdict →
