|---|---|---|---|---|
| Jan 2024 | STRUCTURE | Front windshield cracked n has expanded along the very bottom in the dark black area n spread up into clear glass for no reason whatsoever. Never heard a rock or anything else hit. One day it just started a small looping crack. | Crash: No Fire: No | Unknown |
| Jan 2024 | FUEL/PROPULSION SYSTEM | Strong egg odor from exhaust when temperature is below 0 degrees C or 32F. This is especially the case then the car is started and left to warm up for 5-10 min. The smell goes away after 15-20min. | Crash: No Fire: No | Unknown |
| Jan 2024 | EXTERIOR LIGHTING | Vehicle blinker works at fast rate at all times. In the event that one of the rear turn signals stops working, the vehicle will not adjust the turn signal flash rate frequency to warn the driver that a turn signal is not working correctly. Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment." Ford says 'fast' blinker on all Explorer ST's is by design and normal. | Crash: No Fire: No | Unknown |
| Jan 2024 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | With the Ford Intelli-Cruise enabled in settings, the vehicle automatically adjust the speed while using the cruise control. The vehicle will randomly, quickly, accellerate to a extreme new speed limit it thinks it has detected. For instance, several times while travelling on I-81, with a 70mph speed limit, the vehicle will think the new speed limit is suddenly 85mph and quickly accelerate to that speed. I have attached a photo of the dash displaying that setting the car set by itself. On the flip side, once on I-81, it thought the speed limit was 35mph and quickly slammed on the brakes to slow to 35mph from 70mph. Both are quickly overridden by the driver tapping the brake and cancelling the cruise control. However, both could lead to hazards to other drivers potentially resulting in a wreck, especially the sudden slow to 35mph on the interestate. The dealership says "Yea, it happens and people complain". I have no idea why the speed changes, there are no road signs or other indications to even cause the system to re-evaluate its settings. Ford says Intelli-Cruise uses road signage and other ways to also determine speed (whatever that means). This is a safety issue that needs to be remedied by Ford. However, without NHTSA enforcement, they don't seem interested in resolution.

| Dec 2023 | ELECTRICAL SYSTEM | 11/9/23 our still under warranty, 2021 Ford Explorer Platinum with 20,152 miles on it died at stop sign and would not start. Locked in park and had to be towed to dealer who worked on it for one week and claimed it was fixed. Same problem second time a few days later and dealer claimed it was lose wires and returned to us on 11/28. This last time (happened at a very dangerous onramp location and I thought I was going to get hit by another car while waiting for the police to arrive) they have had it since 12/4 and can not diagnose or fix the problem despite claiming to have done numerous things. Ford (Detroit) CS has been of zero help and will not loan us a car or rent one for us to use. We are supposed to be leaving in a few days for our Florida residence for 4 months without our car being fixed. We have had the car a total of 10 days out of the last 51 and with the holiday weekend being tomorrow and Monday it will be 53 days. I have read about numerous Ford Explorers having this same problem and never getting fixed correctly, only to have repeated software issues. How much is enough for a consumer to finally have protection. Lemon Law has expired and I can not find any information for consumers in our current situation. Please advise. We are [XXX] and this is very stressful to say the least. Thank you! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |

| Dec 2023 | ENGINE AND ENGINE COOLING | The contact owns a 2021 Ford Explorer. The contact stated while driving approximately 30 MPH, the contact heard an abnormal sound coming from under the floorboards. The contact slowed the vehicle to listen for the sound, when the contact depressed the accelerator pedal to move forward, he heard the abnormal sound and described it as the sound of a motorcycle exhaust. The contact stated that he drove forward for a few minutes more when the abnormal noise from under the vehicle was louder and he felt that some object was trapped underneath the vehicle and was hitting the underside causing a loud banging noise. The contact stopped the vehicle and looked underneath the vehicle and observed that the passenger’s side exhaust pipe had detached from the catalytic converter. The contact then checked the driver's side and saw that a crack had opened approximately one inch from where the exhaust pipe was connected to the catalytic convert.

| Nov 2023 | UNKNOWN OR OTHER | I have a 2021 Ford Explorer ST that I purchased as a new vehicle. On 8/27/23 I was driving my vehicle to work. I noticed a loud humming noise upon acceleration when I was approximately 1 mile from work. I drove my car to work, parked it. I attempted to get a Ford dealership to service my vehicle and was informed that it would be "3-4 weeks before they could even look at the vehicle" (Siloam Springs Superior Ford). I managed to find a repair shop 2 miles from the hospital that I work at. As I was driving the vehicle to the shop for repair- the loud humming noise upon acceleration was still present- something very loud fell out from under my car. The right side catalytic converter (a pipe several feet long) was hanging down under my car. I am thankful I was driving at a speed <15 mph and not on the highway. The car was repaired (I have attached the receipt for the repair). Upon further research I found that there were other ST Explorer and regular Explorer models with a customer "courtesy repair" that was offered. No such repair was offered to me. I called in a report to the Ford Dealership (general 1-800- 392-3673 line). I received the case #[XXX] at the conclusion of that call. I brought my car into the shop (Lewis Ford Fayetteville), as per Ford's recommendations, to inquire about reimbursement for my issues- since they are the same issues mentioned in the courtesy repair notice. I was not previously notified of a courtesy repair. Lewis Ford informed me that despite my issue being exactly the same issue noted in the courtesy repair- my VIN number was not a part of the repair. This is a dangerous issue. I am certain that if I was at a higher speed level- my car would have been wrecked. According to the repair shop, they have seen and heard of this same issue with Ford Explorer ST models.

| Oct 2023 | SUSPENSION | I bought my 2021 Ford Explorer brand new and at 44,675 miles my shock absorbers went bad. There was no damage to my vehicle that could have caused it, my car was never in an accident. The dealership that repaired them said there was no indication of what caused it and it is highly unusual. Driving without shocks on my vehicle caused the loss of ability to control the rate of weight transfer when going around corners; this also resulted in increased steering input to navigate turns and uneven tire wear. | Crash: No Fire: No | Unknown |
