2015 Volkswagen Passat Problems

What owners report

Owners of this 2015 Passat report a dominant pattern around the steering wheel: a clicking or crunching noise followed by the airbag warning light and loss of the horn and steering-wheel buttons, which complaints commonly attribute to the clock spring. Secondary themes are stalling or rough running traced to fuel pump and sensor faults, weakened brake feel, and heater core leaks that leave the defroster and passenger-side heat weak. Reports are spread from low mileage up to well over 100,000 miles, and much of the work described was diagnosed at a dealer rather than happening suddenly at speed.

1. 1
   Air bags

   Clock spring failure (airbag light, no horn or wheel

   • 55 complaints (23%)
   • median 54,500 mi at 4.0 yrs old (32 state mileage)
   • owner-quoted repair $700 (median of 5 quotes)
   • filed 2017–2025

   Complaints describe a clicking or crunching sound when the wheel is turned, then the airbag warning light staying on and the horn and steering-wheel buttons stopping altogether. Several owners say the dealer diagnosed the clock spring; some were quoted for the repair, some report the part was backordered, and a few say the component was replaced and the problem returned later. Others describe the light coming on with no noise beforehand. Often reported between roughly 35,000 and 95,000 miles, with several cases just past the 36,000-mile warranty.

   What to check: Turn the wheel lock to lock with the engine running and listen for clicking, and confirm the horn and all steering-wheel buttons work. Ask whether the clock spring has ever been replaced and on what date.

   “I took my vw in at 90000 and it was in need of a steering clock spring, here I am 30k mi later and guess what. I am told this is normal but I think he same breath the manger tells the other customer not to worry about it that it was only 2015s . 400 bucks later !!! And that was half. How is this not an issue or default!! I was literally in the drive thru and honked my horn next thing j know my warning system telling me my airbags suck.”

   “At around 47,000 miles I began hearing a clicking noise when turning my steering wheel. After a day or two of this my airbag light came on. I lost function of my horn and found that out while traveling at highway speeds when some one was merging into my lane without checking to see if it was clear. I also lost all steering wheel mounted controls. I purchased the vehicle used about 27 days prior so I returned to the dealer and was informed I was responsible for the repairs. …”

   Stalling, rough running or no-start (fuel pump and sensor

   • 44 complaints (18%)
   • median 38,000 mi at 4.0 yrs old (31 state mileage)
   • filed 2015–2026

   Owners describe the engine cutting out at low speed, at a stop light, or while turning, sometimes with the battery or EPC light on, and occasional rough idling or shuddering. Dealers in the complaints diagnosed a fuel pump, a fuel pump sensor, or an intake pressure sensor and sometimes an engine wiring harness; a few owners say the fault came back after the repair. Reported anywhere from a few thousand miles to beyond 100,000 miles, with many examples in the 60,000 to 95,000 range.

   Recall 15V028000Recall 15V7050003 related service bulletins

   What to check: Ask for service records showing whether the fuel pump or pump sensor was replaced, and take a test drive that includes idling in gear and a low-speed turn. Watch for a check engine or EPC light.

   “Recently my 2015 vw Passat stalled while stopped at a red light. Dealer advised that it was giving codes for a malfunctioning air intake absolute pressure sensor. After it was replaced under warranty, the engine continued to run very rough and seemed to be sluggish. On taking it back to the dealer I have been advised that the code for the absolute pressure sensor has reappeared and vw suspects that it is an engine electrical harness problem which is due for replacement. …”

   • median 6,175 mi at 1.6 yrs old (17 state mileage)
   • 4 mention a crash, fire or injury
   • filed 2015–2022

   Complaints describe the pedal sinking toward the floor or needing heavy pressure before the car slows, with some owners saying the feel varies with temperature. Several mention that rotors, pads and a fluid flush did not resolve it, and one owner reports the pedal sticking; dealers in these accounts did not always identify a cause. Reported from very low mileage up to around 114,000 miles, including several cases under 50,000 miles.

   Recall 15V373000Recall 15V705000

   What to check: Test the pedal feel from cold and again after the car is warm, and check for brake fluid weeping at the rear wheels and lines. Ask whether the brake assist recall work was completed.

   “Factory recall but original notification from dec-2015 had no resolve or date for resolve. However, when I contacted the vw factory they advised me I could go ahead and make an appointment to resolve at my own expense????? Vw claims something called the sintered cam has the potential to shear off from the camshaft. It sure sounds mechanical to me but vw claims to help correct the this defect they will update our on board computer software???? Huh....... …”

   “My pregnant fiance, her 3yr old son and I were driving on a city street approximately 35mph. A vehicle cut off the truck in front of me and the truck in front of me slammed on their beaks, which made me slam on mine. I slammed on my breaks and it did not stop my vehicle, I tried to use my emergency break and did not stop the vehicle so I swerved over as much as possible to avoid my fiance's passenger side from being hit. I rear ended the truck in front of me. Everyone seatbelts locked except my fiance's. …”

   What to check: Run the heater on both sides and the defroster from cold, look for coolant residue or a sweet smell near the firewall, and ask whether the heater core or its tubing has been replaced.

   “My heater core is bad. There was a previous recall on older Passat models, but for 2015 it is not included. I had to pay $871 to have my heater core replaced, as it started to leak coolant in my car. One of the hoses going to my firewall also busted, so it had to be changed. The car was leaking lots of coolant from under the car too. On 9/11 after they supposedly fixed it on 9/07/19, my low coolant light turned on. I was near dealer, so they said they would look at it. …”

   “Volkwagen passenger seat registers a passenger occupying the seat when a cell phone is placed on the middle part of the seat. Vw regional manager and authorized dealer state car is not showing fault codes, and therefore cannot be repaired. This creates a number of concerns. First, is the seat belt sensor so sensitive that it is sensing the small weight of the phone? (5.04 ounces (143 grams)) or is the nfc or cellular modem of the phone interfering with the sensor? …”

Buying note. Budget for the clock spring and airbag light first, since it shows up across a wide mileage range and owners often report it returning. Also ask for recall proof, then check brake pedal feel, heater output and any history of fuel pump or sensor replacement on the test drive.
