Volkswagen Tiguan headlights problems

Filed Aug 14, 2026 · Acceleration · GA

I am reporting a safety-related electrical defect on my 2019 Tiguan that has been intermittently occurring since March 2026. This typically has happened during the hotter parts of the day when the tempreature in in the 90's. While driving, I get two different warnings that displays; "Check starter system" followed by "ignition-system-shut down". Within a few minutes, the engine continues running but the instrument cluster, HVAC and turn signals lose power. Other electrical systems also shut down like, the radio, navigation, head lamps, and side view mirror adjustment. This creates a serious safety hazard because I lose turn-signal and vehicle-information functions while the vehicle is moving." I have found multiple complaints involving 2019 Tiguans with this exact failure mode, including complaints specifically connecting it to Volkswagen recall 28H7 / the federal safety agency 23V‑604 involving the ignition switch and polyfuse. Volkwagen has not aknowledge, reproduced, nor confirmed this issue. I belive that ithe issue is related to the same problem as Volkswagen's 28H7 / the federal safety agency 23V‑604 ignition-switch recall, which currently applies to certain Jettas. That complaint describes the same combination of engine continuing to run while A/C, instrument cluster, headlights and turn signals lose power. I believe that 28H7 should be expanded to the 2019 Tiguan.

Relates to the Volkswagen Recall: 28H7-Ignition Switch that for some reason is only applied to Jetta's but needs to be expanded to include 2019 Tiguans . In vehicles equipped with a conventional ignition switch, the polyfuse can fail, particularly when the vehicle is operated in high temperature environments. If the polyfuse fails, it can result in the engine stalling while driving and failure of the vehicle's electrical system, increasing the risk of a crash. I have had this issue happen over 5 times since the initial incident last week. Now anything above 70 degrees Fahrenheit causes the interior to "lose power" but the engine will continue to run. The A/C, infotainment system, all the ADAS, instrument cluster, headlights, and turn signals shuts off completely. No brake lights, no blinkers, no odometer reading, nothing. I can still drive (accelerate & brake) when this is happening but without all of those systems working I cannot safely operate this vehicle.

Car beeped and displayed warning stating that Ignition will turn off and Check Starter System on four separate occasions, resulting in loss of all electrical power including but not limited to headlights, brake lights, console display, speedometer, dashboard lights, turn signals, hazard lights a/c, etc. The center console felt very warm. The car needed to be pulled over and ignition turned off for a prolonged period of time before restarting or else the issue would continue. The car does not always start right back up upon first try. It is unsafe to drive a car without any working electronics, especially at night. It is difficult and unsafe to pull over to a safe space without any working electronics, especially at night. Brought car to Vw dealer and they removed and replaced the ignition switch actuator.

On [XXX], my 2024 Volkswagen Tiguan SEL R-Line AWD (VIN: [XXX] ) was damaged in a deer collision, requiring replacement of the right headlight assembly (P/N 5NL941114D/E, adaptive IQ.Light matrix with turning signal). The part was ordered June 9, 2025, via New Motors VW (Erie, PA) but remains on national backorder with no ETA (dealer confirms not even "top 25" priority). The vehicle has been undrivable and unreleasable from Betts Brothers Collision (Titusville, PA) for 194 days (as of Dec 13, 2025). The shop refuses to release it without the OEM headlight for safety reasons—operating with one functional headlight + inoperable turning signal violates FMVSS 108 (S9.1: paired headlamps required for visibility; turning signals per S5.1.1). This creates an unreasonable crash risk (impaired night driving, rural area with no transit). VW Care (Case #[XXX]) refuses ETA, loaner (via Customer Mobility Program), or lease/insurance relief despite $10k+ hardship (6 months payments/insurance + lost use). PA BCP mediation (forwarded Nov 3) and CFPB #[XXX] pending—no resolution. Similar backorders reported nationwide (e.g., 4-6 month waits on forums/X). VW's systemic parts shortage effectively renders the vehicle a safety defect—demanding the federal safety agency investigation for trends/recall/service campaign. No crashes/injuries yet, but prolonged hold endangers if forced release. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On three (3) separate occasions, my 2019 VW Tiguan has produced an error stating "Check Starter System" on the console and shut down electrical systems such as instrument panel, brake lights, headlights, taillights, back up camera, and other electrical systems while driving. All three (3) situations followed the same series of events whereas the car was out in the sunlight on warmer days (70+ degrees) and occurred within 5 or so minutes of starting. After shutting the vehicle off and attempting to restart, the ignition will not always work and the car will not turn over. When it does, the key will need to be turned farther than a normal ignition start and most likely produce an immediate error and electrical system shut down. In the most recent occurrence, I found a parking garage and left the car for around an hour and did not experience the issue for the rest of the trip. It appears that there was a recall for a similar issues with the Jetta models made in the same year (2019).

Aftermarket headlights were purchased online. Manufactured by AKD Aokeding in China. The headlights were installed by a ASE certified tech. The left low beam light went out within minutes while driving. Headlights were removed and internals inspected. The construction of these lights are very unsafe and would not meet any manufacturer specs. Not sure how these headlights would pass any safety compliance. The internal components were loose, unsecure and fragile. The wiring used was very thin approximately 28/30 gauge diameter. Right side headlight displayed excessive heat. These lights and company products need further review for further sales to the U.S. Other complains are online about this manufacturer.

PCV Failure causing the timing cover to leak oil and causing the oil pan to crack. This is a known issue with VW TSI engines. This PCV is a major issue not only causing the damage above but others are having to replace the rear main seal and crank case because of this. It's now in the shop for the next week and I'm out of a vehicle for the next week. This is not the only problem I've had with this vehicle. The last problem I had was the housing unit of the overhead lights, sunroof controls and sos when hanging down and broke out of nowhere. The plastic melted and cracked. It was replaced but was not put back together properly. There are now gaps where it should be tightly sealed. The glove comparent arm is broken. There are wheel bearings issues too we are trying to pin point the issue. The hits keep coming and the car is just a money pit.
