I hope this letter finds you well. I am writing to bring to your attention some serious safety issues that I have encountered with a 2020 Mustang that I purchased from CarMAX, West Valley on September 24, 2023. Soon after taking possession of the vehicle, I noticed a malfunction with the airbag system. It is disheartening to report that I had to endure a three-day wait to have the necessary repairs carried out. The delay in rectifying this crucial safety feature is highly concerning, as it exposes both the driver and passengers to unnecessary risks. Unfortunately, the problems did not end there. Shortly after the airbag issue was addressed, the engine light illuminated on the dashboard. Despite my efforts to troubleshoot the problem myself, the light remained illuminated, indicating a persisting issue with the engine. Not only did this cause me considerable inconvenience, but it also raised concerns about the overall reliability and safety of the vehicle. The most alarming incident occurred on October 2, 2023, when my car unexpectedly broke down while I was driving on the freeway. This unexpected failure not only posed a significant risk to my safety but also left me traumatically shaken by the experience. I cannot emphasize enough the fear and anxiety I felt as I navigated the dangerous situation caused by the vehicle's sudden malfunction. I am deeply disappointed by the lack of quality control and the subsequent safety hazards that have plagued my 2020 Mustang. As a consumer, I have a reasonable expectation that the vehicle I purchase will be safe and reliable. It is distressing to find myself in a situation where my safety and wellbeing are compromised due to these issues. I have taken my concerns up with CARMAX and I am waiting for a response. It is my hope that they will investigate the matter and take measures to address it. I will not stop fighting for the safety of my family and myself.

Intermittent loss of throttle with wrench light. Engine goes into derate, have to shut off car, let sit for 3-5 minutes, restart then ok until it occurs again. Loss of throttle at any time is unsafe. Two Ford dealers have tried to repair with no luck. They have replaced the throttle pedal assembly, the throttle body, and now the PCM. Problem is still present. Have an ongoing Ford customer service case #CAS44568044-D6G8F8. Still awaiting resolution. Vehicle is still under 3/36 Base warranty. Problem has been ongoing for a little over a year now.

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

Driving at posted speed, went to pass a vehicle and the accelerator stuck in full open (down) position. Car lurched forward and luckly I was able to put it on neutral, pull over and manually un-stick the accelerator pedal.
