28–34 mpgcombined; city 24–30, highway 33–41; every version of this model year
Five years of fuel
$9,550–$11,600U.S. average; Ohio $8,540–$10,370 at local prices; every version of this model year; fuel only, not other costs of owning it; 15,000 miles a year, at EIA fuel prices for the week of Oct 12, 2026
NHTSA's VIN data lists these trims for the 2021 Jetta. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 69 complaints with NHTSA about the 2021 Jetta. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 4 recall campaigns for the 2021 Jetta over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2021 Golf GTI, Jetta GLI, Jetta NF, Arteon FL, Tiguan LWB, 2022 Taos, Jetta PA, Tiguan PA, 2021-2022 Atlas Cross Sport, and Atlas FL vehicles. The manufacturing process of the eMMC memory module in the infotainment system may cause the rearview camera image not to display. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
Risk: A rearview camera that does not display an image reduces the driver's rear view, increasing the risk of a crash.
Remedy: Dealers will update the infotainment software, free of charge. Owner notification letters are expected to be mailed September 16, 2022. Owners may contact Volkswagen's customer service at 1-800-893-5298. Volkswagen's number for this recall is 91DV.
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2020-2021 Jetta and Jetta GLI vehicles. The air bag control module was welded in the incorrect position.
Risk: Incorrect positioning of the air bag control module can cause the vehicle's air bags to deploy improperly during a crash, increasing the risk of injury. Additionally, the vehicle's air bags can deploy unintentionally, increasing the risk of a crash.
Remedy: Dealers will replace the air bag control module, free of charge. Owner notification letters were mailed on January 28, 2022. Owners may contact Volkswagen customer service at 1-800-893-5298. Volkswagen's number for this recall is 69CK.
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2021 Volkswagen Tiguan Long Wheelbase and Jetta vehicles. Bolts may be missing from the front seat tracks.
Risk: The seat can move front and back without restriction if bolts are missing, increasing the risk of injury during a crash.
Remedy: Volkswagen will notify owners, and dealers will inspect the front seat tracks and, as necessary, install the bolts, free of charge. The recall began February 18, 2021. Owners may contact Volkswagen customer service at 1-800-893-5298. Volkswagen's number for this recall is 72L6.
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2021 Atlas Cross Sport, Tiguan LWB, Jetta NF, Jetta GLI, Golf GTI, Atlas FL and Arteon vehicles. The rear view camera could malfunction during an ignition cycle, leading to a black screen or infotainment system freeze. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
Risk: A black or frozen rear view image reduces the driver's visibility when reversing, increasing the risk of a crash.
Remedy: Volkswagen will notify owners, and dealers will update the infotainment system software, free of charge. The recall began December 11, 2020. Owners may contact Volkswagen customer service at 1-800-893-5298. Volkswagen's number for this recall is 91BB/91BC.
