Quick Answer: A Mercedes-Benz EQE head-up display that repeatedly flickers, distorts, turns green, or shows pixelation — and keeps failing after major repairs — may support a California lemon law claim under the Song-Beverly Consumer Warranty Act (Cal. Civ. Code § 1793.2). In one 2023 EQE SUV’s documented repair history, the instrument-cluster control unit was replaced twice, and the head-up display and its wiring harness were also replaced, yet the same display malfunction — tied to diagnostic fault code U112083 — returned before the vehicle reached 20,000 miles. The owner’s lemon law claim was resolved through settlement.
Key Takeaways
- The 2023 EQE SUV discussed here had display flickering over bumps, static, a green screen, and pixelation affecting both the head-up display and instrument cluster — all documented on repair orders with fault code U112083.
- Two instrument-cluster control unit replacements, a new head-up display, and a new wiring harness did not permanently fix the defect.
- When the same malfunction survives multiple major component replacements, the repair history itself becomes powerful lemon law evidence.
- A defective display is not a cosmetic issue: it interferes with information the driver expects to see while operating the vehicle, and repeated failures reduce a luxury EV’s value.
- The lemon law claim arising from this repair history was resolved through settlement.
A 2023 Mercedes-Benz EQE SUV experienced repeated warranty problems involving its head-up display and instrument cluster. The display flickered, distorted, and showed static while the vehicle was being driven, particularly when the SUV traveled over bumps or uneven road surfaces.
Despite several substantial repair attempts — including replacement of the instrument-cluster control unit, wiring, and the head-up display itself — the defect later returned. The lemon law case was later resolved through settlement.
The First Complaint: Head-Up Display Flickering Over Bumps
The vehicle was first presented for repair after the driver reported that the head-up display flickered when the SUV traveled over bumps.
During testing, the technician confirmed that the display intermittently showed distortion and static. Diagnostic testing revealed fault code U112083, described in the repair records as an internal checksum error.
The technician inspected the cable running between the instrument cluster and the head-up display. The records indicate that moving or tapping components caused the distortion to return. The dealership concluded that the instrument cluster had an internal loose connection and ordered replacement parts.
When the vehicle returned, the dealership replaced the instrument-cluster control unit, performed programming and startup procedures, cleared the fault codes, and test-drove the vehicle.
The Flickering and Green-Screen Problem Returned
The head-up display problem later returned. The repair records documented that the display flickered when the SUV traveled over bumps and that the screen sometimes appeared green.
The vehicle was also presented with a coolant-level warning that remained illuminated.
During a later service visit, the dealership topped off the coolant and performed a software campaign involving the drivetrain separator-clutch control unit. The head-up display complaint remained part of the repair visit.
The Dealership Replaced the Head-Up Display and Wiring Harness
The SUV returned again with relatively low mileage because the head-up display continued to flicker over small road irregularities.
The dealership again identified fault code U112083 and performed an extensive inspection. According to the repair records, technicians removed dashboard components, the instrument cluster, touchscreen, glove compartment, and other interior components to access the affected system.
After finding the wiring connections intact, the dealership determined that the head-up display had an intermittent internal fault. It replaced both the head-up display wiring harness and the head-up display unit, programmed the new display, and cleared the fault codes.
That visit also included a separate repair to the center-console storage compartment because its sliding door would not close properly.
The Display Failed Again After Major Repairs
The SUV later returned with fewer than 20,000 miles because the head-up display was again flickering while the vehicle was being driven.
This time, the technician observed abnormal pixelation in the upper-right portion of the head-up display. Similar distortion appeared in the instrument-cluster display when it was placed in navigation mode.
The dealership performed a software update and coding procedure, but the malfunction returned after several minutes. Technicians then inspected the related control modules, connectors, wiring harnesses, and display cable. A temporary replacement cable did not correct the condition.
The dealership ultimately determined that the instrument-cluster control unit had another internal malfunction and replaced the instrument-cluster control module again.
The Same Mercedes-Benz Display Defect, Repaired Again and Again
The documented repair history included:
- Repeated head-up display flickering over bumps
- Static and visual distortion
- A green display screen
- Pixelation affecting both the head-up display and instrument cluster
- Diagnostic fault code U112083
- Replacement of the instrument-cluster control unit
- Replacement of the head-up display
- Replacement of the head-up display wiring harness
- Software updates, programming, and control-module coding
- Another replacement of the instrument-cluster control unit after the problem returned
This repair history is significant because the same basic display malfunction continued after several major repairs. Replacing a control module, wiring harness, and head-up display would ordinarily be expected to correct the concern. When the defect continues or returns anyway, the consumer may reasonably question whether the vehicle can be permanently repaired at all. In this case, that repair history supported a lemon law claim that was resolved through settlement.
Can Repeated Mercedes-Benz Electrical Problems Qualify Under California Lemon Law?
California’s lemon law, the Song-Beverly Consumer Warranty Act, may apply when a manufacturer or its authorized dealership has been given a reasonable number of opportunities to repair a warranty-covered defect that substantially impairs the vehicle’s use, value, or safety.
There is no single number of repair attempts that automatically makes every vehicle a lemon. Important considerations can include:
- How many times the vehicle was presented for the same problem
- Whether the dealership verified the malfunction
- Whether major components were replaced
- Whether the problem returned after repairs
- The number of days the vehicle was unavailable
- Whether the condition affects the vehicle’s use, value, or safety
California’s statutory presumption (Cal. Civ. Code § 1793.22) may also provide a guideline in some cases — for example, four or more repair attempts for the same defect (together with any direct notice to the manufacturer the warranty materials require), or the vehicle out of service more than 30 cumulative days, within the first 18 months of delivery or 18,000 miles, whichever comes first.

Electrical and display defects should not be dismissed merely because the vehicle can still be driven. A defective head-up display interferes with information the driver expects to see while operating the vehicle. Repeated distortion, flickering, or pixelation can also substantially reduce the value and reliability of a luxury electric vehicle.
What Mercedes-Benz EQE Owners Should Do
Owners experiencing recurring display, electrical, or software problems should keep every repair order, even when the dealership reports that no fault was found.
The repair order should accurately describe what the driver experienced, including:
- Whether the display flickers or goes blank
- Whether the screen becomes green or distorted
- Whether the problem occurs over bumps
- Whether the defect affects the instrument cluster
- Whether the problem returns after software updates or part replacement
Videos can also be valuable when a problem is intermittent. A recording of a flickering or distorted display may help establish that the defect exists even when it does not occur during a short dealership test drive.
Consumers should also review their repair records to determine whether the dealership repeatedly addressed the same underlying condition under different repair descriptions.

Frequently Asked Questions
Is a head-up display defect serious enough for a California lemon law claim?
It can be. A head-up display presents speed, navigation, and warning information the driver relies on while operating the vehicle, and a warranty defect may support a claim under the Song-Beverly Consumer Warranty Act when it substantially impairs the vehicle’s use, value, or safety and is not repaired within a reasonable number of attempts. Repeated failures in a luxury electric vehicle can also substantially reduce its value.
The dealer already replaced the display and the instrument cluster. What if the problem comes back again?
Return the vehicle promptly and make sure the new repair order lists the prior replacements and states that the same malfunction returned. In the EQE repair history described above, the defect returned even after two instrument-cluster control unit replacements, a new head-up display, and a new wiring harness — a repeated failure after major repairs strengthens, not weakens, the repair history. That history supported a claim that settled.
Does fault code U112083 mean my Mercedes-Benz EQE qualifies as a lemon?
No single diagnostic code makes a vehicle a lemon. A stored code like U112083 matters because it documents that the malfunction is genuine and detectable, which is especially valuable for an intermittent defect. What determines a lemon law claim is the complete repair history: how often the problem was reported, what was replaced, and whether the defect kept returning.
A note on deadlines: California lemon law claims are subject to filing deadlines. Procedural changes that took effect in 2025 (AB 1755 and SB 26) added pre-suit notice requirements and filing windows — generally one year after the express warranty expires and no more than six years after original delivery — for manufacturers that opted into the new process. Whether those rules apply to your claim depends on your manufacturer’s election, so acting promptly is the safest course. Contact me here.
Disclaimer: Prior results do not guarantee a similar outcome. Every California lemon law claim depends on its own facts, repair history, and warranty coverage.
