Why does my Ford EcoSport's RPM jump or shudder while cruising?

Short answer: On the EcoSport's automatic, an RPM jump of a few hundred at steady speed with a slight jerk, or a shudder when cruising, is usually the torque converter slipping (the fluid coupling between engine and transmission, which has a clutch that locks it at cruising speed). Owners report dealers replacing torque converters under warranty, and Ford sometimes helping with cost after warranty.

Symptom: The tachometer jumps a few hundred RPM while cruising, a slight jerk or shudder, or a feeling like driving over rumble strips.

What to check first

1. Note the speed and whether it happens at light throttle.
2. Have a Ford dealer scan the transmission and road-test it with you in the car.
3. Ask about warranty and goodwill, even if you're slightly out of coverage.
4. Check your VIN for recall 25V126 (front half shafts on 2021–2022).

Likely causes

1. Slipping torque converter or lock-up clutch. EcoSport Forum owners had dealers confirm a slipping torque converter, and several had it replaced.

What it usually costs

An EcoSport Forum owner at about 70,000 miles was quoted $2,500, and Ford covered part of it. Others had the torque converter replaced under warranty, and one 2021 owner got extra warranty coverage added. Ask Ford before you pay.

Is it safe to keep driving?

Usually drivable for a short time, but slipping gets worse and can lead to transmission damage. Get it checked soon. Verify with a mechanic.

DIY or shop?

Shop. Torque converter replacement means removing the transmission.

Recalls, bulletins and complaints in plain words

• No recall covers the torque converter.
• Recall 25V126 (2021–2022 EcoSport): a separate issue where the front half shafts (the axles that drive the front wheels) may disconnect from the transmission, causing a loss of drive power. Dealers inspect and replace parts. If your car is part of this recall, the dealer fixes it for free.
• NHTSA complaints: 160 keyword-matched complaints for Ford EcoSport 2018–2022 (of 1,859 unique complaints queried, NHTSA complaints API by model year, queried 2026-10-17; keywords: shudder, torque converter, transmission, jerk, hesitat, slip).

What owners report

• In 2019 EcoSport RPM issue, an owner at about 70,000 miles saw RPM jump about 300 at cruising speed with a slight jerk. The dealer said the torque converter was slipping, quoted $2,500, and Ford paid part of it. Other owners had torque converters replaced under warranty; one said it came back a few thousand miles later.
• Owners also discussed torque converter, not transmission, and on r/FordEcoSport owners asked whether 2019 EcoSport transmission issues are common and about jerking after the first gear change.

My take

My advice as a former finance manager: if you have an extended warranty on an EcoSport, read the transmission section now, before anything goes wrong. Know whether the torque converter is listed as covered.

Vehicle focus: 2018–2022 Ford EcoSport with the 6-speed automatic.

Safety / mechanic note

A slipping transmission can get worse quickly. Verify with a mechanic.
