Since its launch in 2017, the LC has gained a reputation for exceptional build quality and smooth performance. However, even a luxury coupe of this calibre can develop issues over time. In this guide, we explore the Lexus LC model problems, and typical UK repair costs to help owners and buyers understand what to expect.

Routine Maintenance Costs
| Service Type | Description | Typical UK Cost |
|---|---|---|
| Minor Service | Oil and filter change | £300 – £400 |
| Major Service | Fluids, filters, spark plugs | £700 – £1,000 |
| Hybrid Health Check (500h) | Battery and system diagnostics | £100 – £250 |

Is the Lexus LC Reliable?
Yes. The Lexus LC is one of the most reliable luxury coupes available.
The 5.0-litre naturally aspirated V8 in the LC 500 has a proven record for durability. It’s used in other performance models like the RC F and GS F. The LC 500h hybrid is equally robust, with issues typically limited to software calibration or minor electrical problems.
Both models benefit from Toyota’s strict quality control, which keeps long-term ownership costs low compared to German competitors.
Buying Advice and Pre-Purchase Inspection
If you’re buying a used Lexus LC, it’s important to check for:
- Full Lexus service history
- Suspension or steering noises
- Brake wear or corrosion
- Infotainment system responsiveness
- Battery condition
A CAREXAMER pre-purchase inspection can identify any mechanical or electrical issues early. This is especially useful for cars that have been stored for long periods or driven infrequently.
