2022 Mercedes-Benz AMG SL63

MBUX system would not turn on. Warnings of Blind Spot in operatable, Parktronic not operatable. Was not able to access any features through MBUX. Climate Control, Operation of Covertable Top, Maps, all options run through MBUX. It was a safety issue because the battery light comes on, after being on charge, and without access to MBUX, you do not know if the car will stall on the freeway, or at a stop light. Safety issues also around front lift without cameras access. The vehicle was inspected at the Mercedes Benz Dealer and they fixed it, but after a day, the battery still isn't charging after numerous attempts and recalls on 12v rewiring. Since I have bough the vehicle, many warning lights have always come on, been ficed and then come back on.

When driven on the highway, speed drops abruptly down (65 mph to 40 mph) stuck on 4 or 3rd gear in this automatic 9 speed transmission and gear won't shift up causing engine rpm rise over 3000 & gas pedal won't have effect even it was pushed down to floor all the way. Almost rear ended in multiple occasion & it is extremely dangerous to change lane to get off to safety as car does not respond to throtle up or gas pedal to speed up. Dealer was not able to duplicate issue in two service visit & this already happened third time in a raw and car is back in dealership for diagnostic. No warning nor malfunction light at all when this happen

Complaint During part of the steering movement, it feels heavier or more difficult to steer in the same spot every time. OR Rattling, humming, dry sliding/gravel noise from the electric steering system when steering (see attachment). Complaint does not impact the ability to safely steer or control the vehicle. Cause Ball screw drive (KGT) of electric steering damaged by: 1. External force due to: ‑ Hitting the curb/posts with the front wheels. ‑ Driving over obstacles (e.g. pothole/ threshold/ speed bump/ gully) at an inappropriate speed. 2. Corrosion/ water ingress through a damaged boot (see attachment). ‑ Cracks (1) ‑ High pressure cleaner (2) ‑ Animal bite (3) See various examples listed in the attachments for examples of outside influence. Remedy Remove boot clamps closest to steering gear housing on both left and right (as seen in "Steering Rack Boot Clamp Location"). Pull back boot and inspect for rust, broken end stops, water, or any other anomalies. Replace electric steering. Note: Steering gears replaced due to outside influence or damage must not be claimed under warranty!

Complaint • Harsh 1‑2, 2‑3, and/or 3‑4 shift • Jerky shifting • Jolting when accelerating from stop Cause Insufficient software application causing elevated K81/K27/B05 fill time adaptations and elevated torque adaptations for concerning shift. Note: Shift quality in E Performance models can be affected if the HV Battery state of charge (SOC) reaches 25% or below. Remedy Check VGS software level, and follow relevant remedy instructions. (see attachment) AMG 43 models with VGS software levels up to 22A: As of 4/18/2025, an aftersales software improvement has been released. This software has been implemented in production as of model year 2024, however this LI should still be followed if the concern is present. 232 ‑ A0009025699 206 ‑ A0009025599 Please ensure your Xentry machine is up to date with the latest Add Ons and continue with the following steps: Note: ALL steps must be performed to rectify concern 1. Perform software update all control units included in VGS software update. 2. Check transmission oil level and correct, if necessary (transmission oil temperature > 60 °C) 3. Perform Xentry Valve Flushing procedure at least 3x 4. Perform resetting of deceleration values (VGS > Special Procedures > Special procedure > Resetting learned values Deceleration mode) 5. Perform a standstill adaptation, then read out new EEPROM data 6. Perform driving adaptation(s) while adhering to the below parameters for at least 20‑30 miles. Note: There is no menu in Xentry for this procedure. We recommend displaying the torque in the instrument cluster. If all below parameters are met at the time the shift, a driving adaptation will automatically occur. Harsh 1‑2 Perform a driving adaptation of 4‑5 (adapts K81 for the 1‑2 shift) Harsh 2‑3 Perform a driving adaptation of 6‑7 (adapts B05 for the 2‑3 shift) Harsh 3‑4 Perform a driving adaptation of 3‑4 (adapts K27 directly) ‑ See attached PDF for min/max torque, and RPM parameters ‑ Transmission oil temperature > 30°C (>86°F) ‑ Level track (no incline/decline) ‑ Slippery drive program ‑ Display the torque in the instrument cluster ‑ Constant engine torque ‑ Do not shift via paddle AMG 63 models with VGS software levels up to 22A: No aftersales software resolution is planned. Perform above steps and release the vehicle. If the vehicle returns and already had ALL steps in this LI performed on a previous visit, or has software level 23A and newer: Please submit a TIPS case to the Powertrain inbox and ensure the following is included: ‑ Initial Quick Test w/ Freeze Frame Data ‑ VGS Control Unit Log ‑ Initial EEPROM (before any adaptations or Xentry procedures were performed) ‑ Detailed vehicle history of the complaint

Complaint Traffic sign symbol for "Traffic Sign Assist" is blinking in instrument cluster without obvious cause usually with one of the following scenarios: • Flashing without a speed limit ("‑ ‑"). • Flashing when current vehicle speed is under speed limit. • Flashing between US speed limit symbol and European speed limit symbol. NOTE: • Verify that the concern falls under one of the attachment videos. If not, then it is outside of the scope of this LI. • This also does not cover "Traffic Sign Inoperative" messages on the instrument cluster. Cause There are two identified reasons for this concern: 1. Country code information stored incorrectly at a particular geographic latitude range. 2. Incorrect reference data when the vehicle is started and a GPS signal is not immediately available. Remedy Update head unit software to latest version and the re‑check function in the same location. If vehicle is still exhibiting one of the symptoms as described exactly as in the complaint section or as shown in the video attachments, open a TIPS case to the Body/Chassis/Entertainment inbox with the following: • Video of the concern. • Exact location (latitude and longitude is best)
