2020 Ford Ranger: sudden loss of power

Filed Aug 28, 2026 · Transmission · NC

While driving my 2020 Ford Ranger, the transmission has repeatedly exhibited unexpected and unintended gear changes, including sudden downshifts or gear changes without driver input, hesitation, and abrupt loss of power during acceleration. These problems have occurred during highway merging, pulling into traffic, and city driving. On 08/14/2026, while accelerating to pull into traffic, the vehicle suddenly lost power, creating a hazardous situation as vehicles approached from behind. I have also experienced instances in which the transmission unexpectedly shifted or hesitated without warning, causing the vehicle to lurch or slow unpredictably in traffic. This condition creates a serious safety hazard because an unexpected loss of power or unintended gear change can prevent the vehicle from accelerating when needed, such as when merging, passing, pulling into traffic, or avoiding a collision. The unpredictable behavior increases the risk of a crash and endangers both the driver and surrounding motorists. The vehicle was taken to Crossroads Ford of Indian Trail on 08/14/2026, where it was diagnosed with a failed or failing 10R80 automatic transmission. At the time, the vehicle had approximately 57,500 miles and was approximately 5 years and 7 months old, which is 7 months beyond the manufacturer's bumper-to-bumper warranty. I have maintained the vehicle according to Ford's recommended service schedule throughout my ownership. I am aware that Ford has issued prior service bulletins and customer satisfaction programs related to 10R80 transmission issues, including TSB 18-2274, 20-2339, 22-2139, 23-2250, and 24-2254, although I have not confirmed whether any of them directly apply to this VIN. I am filing this complaint because the symptoms I experienced—unexpected gear changes, hesitation, lurching, and sudden loss of power—present an immediate safety risk to me, my passengers, and other drivers on the road.

I was traveling south on I-35 going up a long steep hill and my transmission started to hard shift and then I would lose power and when I would accelerate, I had no power it would just stall out so I merged to the right side in case I had to pull over because I thought the engine had died. When I reached my destination, I looked under my truck to discover fluid on the under carriage at that point I knew the transmission had blown a seal or a high-pressure hose. So, I left the truck there and the next day had it towed back to my house. There were times I had slowed down so much that traffic almost hit me.

In May of 2025, the transmision of my 2020 Ford Ranger with 35,000 miles jolted and bucked expectadly at traffic lights, I had full loss of engagement of the transmission several times, engine would rev to 4000rpm and no transmission enagement. These issues happened while at traffic stops and while driving in normal conditions. This presented on one occasion with powertrain warning light and the truck going into "limp" mode. This then reverted to no light but the issues continued, with inconsistent jolts, unable to gain speed. The jolting was abrupt and truck "leapt" forward at speed. During loss of power incidents, I was left with no ability to accelerate away from road hazards. This would have been extemely dangerous if I were turning across traffic. Ford refused to acknowledge any issues. An independent mechanic diagnosed this as a full transmission failure.

Bought 2020 Ford Ranger Lariat in March 2024 with 13k miles. I have had no issues and have kept up maintenance needed. Vehicle currently has 19,128 miles and on 4/17/26 while driving the vehicle lost power. I was able to pull over and immediately called the dealership where vehicle was purchased and had towed to their facility for diagnosis. There we no warning lights prior to losing power. The dealership informed me a new transmission is needed pulling codes P0751 and P2700. The cost they informed me for replacement was $10k +/= indicating the Power Train warranty had expired in 2025. (5 yr/60,000) I find this appalling that at 19k I am responsible to replace something that has clearly had issues in past. Their only option was to replace transmission or they could take apart and overhaul to fix the codes which could be cheaper but also may result in transmission replacement anyways which will cost more in long run.

When starting to accelerate, the automatic transmission shifts hart into second or third gear, and sometime has no power, like it is idling for 5 to 7 seconds before engaging. The problem has been reproduced and confirmed by Quirk Ford of Augusta, Maine who said I must have had a faulty transmission from the factory. The safety issue is hesitation from the occasional loss of power during the hard shift which could put one in danger of being rear ended. The were no warning indicators except the sudden jarring during hard shift. Other than the problem being diagnosed by the dealer, it has not been inspected. Hard shift first appeared around 75,000 miles. Dealer flushed and Changed fluid. Reappeared with loss of power during around 130,000 miles. Transmission being replaced 12/15/25 at $9200. Ford basically said it was my problem. I have had two ford rangers before that I drove for over 230;000 miles each without any transmission issues. Clearly the 10 speed transmission is flawed and needs a recall.

While driving on the highway the tensioner pulley snapped off from the timing cover. Losing the pulley caused my serpentine belt to become tangled in the radiator fan. My engine over heated and I lost power steering. This left me stranded on the side of the highway for hours. I took the truck to ford, the origional quote was 3900, but they worked with me and got it down to 1765.

December 2024 experienced loss of power, was able to have a Certified Ford maintenance facility look at it, but found nothing, codes cleared. Codes presented were Hill Start Assist Warning, pre-collision Assist Warning, power train malfunction/reduced power. Drove the vehicle 3 hours in below zero temp. The next day after the vehicle sat in freezing temps, drove approximately 5 miles on snow covered roads when experienced loss of power. Went from 55 miles an hour to less than 10 MPH in about 200 feet. No traffic behind me, drove the remainder of the distance (another 5 miles) at 5-10 mph. Had to have the vehicle tow to a dealership where I was informed that there is a service bulletin on the throttle body. They ended up dumping approximately 2 cups of water from the throttle body. Ford replaced the throttle body at no charge. I called Ford Customer service to share my concern. The fact that the vehicle speed fell off so quickly was what prompted me to call.

The Ignition Coil and spark plug failed and caused the vehicle to misfire & lose power under load. The vehicle is available for inspection. Sudden loss of power could have caused a collision due to the vehicle suddenly slowing without warning in traffic conditions. Ford Motor company is aware of the problem and has a service bulletin describing how the lack of an engine cover allows water to get into the spark plug wells causing the failure to occur. Ford's fix is to install the engine cover and replace the damaged components. But will only do so under the standard warranty. Ford was notified of the problem with my vehicle while it was well within warranty. But because a dealer could not schedule an appointment until 9 days after the standard warranty expired, they have denied coverage. Dealership has inspected the components and confirmed problem is related to service bulletin. Check Engine light came on and was flashing when problem occurred. No prior warning or symptom until problem occurred.
