Prologue vs Model 3

The 2024–2025 Honda Prologue can experience a sudden loss of motive power due to a Battery Energy Control Module (BECM) software error that falsely triggers a high-voltage shutdown. This occurs without warning, shifting the vehicle to neutral or stopping it completely, which increases the risk of a crash or being stranded. The fix is a dealer-performed software update under a safety recall, free of charge to owners. If the vehicle is out of warranty, a dealer flash typically costs $150–$250.

The 2024–2026 Honda Prologue, especially early 2024 builds, suffers from parasitic 12-volt battery drain caused by the Ultium platform's power management software failing to de-energize modules when parked. Symptoms include a completely dead vehicle after 12–48 hours, with doors failing to unlock and no dashboard response, often requiring a jump start or tow. Dealers replace the 12V battery and apply a software update; under warranty this is free, but out-of-warranty replacement costs roughly $200–$300.

The 2024–2025 Honda Prologue's Google-based infotainment system frequently freezes, shows a black screen, or randomly reboots, cutting off climate controls, Apple CarPlay/Android Auto, and camera functions. This can distract the driver and cause loss of critical vehicle features. The remedy is an OTA or dealer-flashed software update, free under the factory warranty; if not covered, dealer diagnostics and flashing typically cost $100–$200.

The 2024–2026 Honda Prologue, particularly early 2024 builds, can fail to initiate DC fast charging, stop charging unexpectedly, or limit charging speed to about 40 kW instead of the rated 150 kW due to a bug in the charging control logic. This shows a 'Charge Fault' error and makes road trips impractical, potentially stranding the driver at a charging station. The fix is a software update to the BECM and Vehicle Control Module, covered under warranty; no out-of-pocket cost is documented beyond diagnostics.

The rear-view camera on Model 3 vehicles from the 2019-2020 model years can fail because repeated opening and closing of the trunk damages the coaxial cable feeding the camera, potentially causing a black screen or complete failure. This increases the risk of backing collisions. The issue was addressed in a December 2021 recall that covered 2017-2020 Model 3 vehicles, with a free remedy; out-of-warranty harness repair is estimated to cost a few hundred dollars but no independent cost estimate is available.

Certain 2021-2022 Model 3 vehicles with Autopilot, and some 2020 models, may experience phantom braking where the car slams on its brakes at highway speed with no visible obstacle, which can cause rear-end collisions and erode driver confidence. This was investigated by NHTSA in February 2022 after numerous complaints. Tesla addressed it with free over-the-air software updates, so no owner-paid repair is typically needed.

Front upper control arm ball-joint wear can cause creaking or clunking sounds over bumps and while steering on Model 3 vehicles from 2019-2023, especially earlier builds. This can lead to uneven tire wear and, in severe cases, loss of suspension integrity. Out-of-warranty replacement typically costs between $400 and $900 per side including parts and labor.

Tesla Model 3 vehicles from 2019-2023 can experience premature failure of the 12V auxiliary battery, often within 2-4 years, leading to warnings like '12V battery needs service' and potentially leaving the vehicle inoperable. The battery may fail while parked, causing a sudden inability to unlock or start the car. Replacement at a service center typically costs between $250 and $450 including parts and labor.

In December 2023, Tesla recalled over 2 million US vehicles including the Model 3 from 2019-2023 because NHTSA found that Autopilot's controls may not sufficiently prevent driver misuse, increasing crash risk. The remedy was a free over-the-air software update to add more prominent alerts and checks. No owner out-of-pocket cost is associated with this recall.
