New Car Assessment Program

The 2023VOLKSWAGENID.4 carries 729 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 97 crashes, 6 fires, 50 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2023 ID.4 is electrical system with 188 filings, followed by unknown or other (96) and vehicle speed control (44). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 13 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 37 investigation files overlapping the 2023 ID.4, and 2 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration. Use the related-complaint feed below to read raw owner narratives before deciding whether any pattern here affects your specific use case.

VW has informed me that my 2023 ID4 has a faulty battery that is at risk of catching fire. The VW corporate representative told me not to charge at fast charging stations and to keep it clear from my property because of the risk of it catching fire. VW has not issued the recall yet as they dont have a solution, but warned me about the dangers. They said they don't expect to issue the recall until mid march. I also talked to a VW dealer and they said when the recall comes out that the wait time to fix will be significant. In the meantime, I feel very unsafe driving , charging, parking this car.

Abnormal inside tire wear leading to blow outs and flats. TSB 42M6 available for alignment, adjustment bolts and camber adjustments but it was not sent to my car and I've had to replace 2 sets of rear tires due to uneven wear. Mileage currently is at 35k. Dealer states no issues with suspension or alignment but can't explain the uneven wear. First time was in October 2024 and then this time February 2026. Car was newly driven January 2023. Dealer is asking me to pay each time for new tires. Money or tire sales for them over my safety and the safety of others on the freeway shouldn't be the priority. I could've been in an accident or a rollover twice now. Fixing the actual issue is being neglected. The TSB should include my vehicle and should be a safety recall.

This vehicle is a total safety hazard due to two distinct failures: ​1. Unresolved Door Defect (14+ Months): For over 14 months, the vehicle has suffered from 'Self-Opening Door Handles.' Despite 4 repair attempts, the manufacturer has failed to fix this, posing a risk of doors opening while driving. ​2. Fire Risk & Use Restriction (Current Recall 26V-028): Currently, the vehicle is under a 'High-Voltage Battery Fire Risk' recall. The manufacturer has no remedy available and advises to 'Park Outside' and 'Away from Structures,' while also advising against fast charging. ​Conclusion: I am stuck with a car that has doors that open on their own and a battery that might catch fire. The manufacturer refuses to repurchase this unsafe vehicle. I request an immediate investigation.

Date/Time of Incident: 1/29/36 at approximately 5:44 PM Location: Small school parking lot Vehicle: 2023 Volkswagen ID.4 On 1/29/36 at approximately 5:44 PM, I was pulling out of a parking space at low speed in a small school parking lot in my 2023 Volkswagen ID.4. As I began to move, the vehicle suddenly accelerated on its own, the steering would not turn left, and the car did not respond to braking, moving at an abnormal rate of speed over a very short distance. Prior to this, there had been no warning messages or alerts, except a routine notification to service the car in 1,000 miles. The collision involved three vehicles: my VW, the main car I hit, and a rental car. My car spun and veered sideways, the parked SUV on the right was pushed sideways, forming a rough “H” pattern, and the rental car went up onto a rail ramp where children walk. My grandson observed the car’s tires spinning at impact, and he hit the seat behind me. Without the parked cars, the vehicle would have c

Level 2 (slow) charging often stops after only 5–10% of charge is added but is unpredictable. Even when charging on a level 3 charger, the vehicle often charges to random levels below 80% (the level to which the vehicle is supposed to charge). DC fast charging is slow and often struggles to reach 40%-50% within a reasonable time. Charging equipment often reports significantly more energy delivered than vehicle displays. This has occurred at multiple charging locations (and multiple chargers). The vehicle’s range has been severely reduced. The vehicle’s range is dramatically less than it used to be. The battery is often drained and needs to be recharged in less than 100 miles. The vehicle often loses power.

The navigation and GPS shows the car is hundreds of miles from where it actually is. In the event of an accident, the automatic emergency call will not show the proper location of the vehicle making any first responder assistance impossible. This is not a new problem for VW as several models including the ID.4 have had this problem as documented on several on-line owner groups. eg. https://www.vwidtalk.com/threads/navigation-and-sign-errors.13194/ The problem, as verified by my local VW dealer on Dec 30 2025, is the 5F module which controls the navigation and other functions that appear on the main screen (eg backup camera). This problem first happened in early December 2025. The navigation screen shows the car miles from where it actually is. The vehicle info screen will not display speed limit signs, or any gps related items (accidents, charging stations, etc). The car has been to the dealer twice to fix this problem. First time for 3 days and it is still there the second time, 4
