2020 Mercedes-benz Sl450 problems
The Mercedes-Benz R107 and C107 are sports cars which were produced by Mercedes-Benz from 1971 until 1989, being the second longest single series ever produced by the automaker after the G-Class. They were sold under the SL (R107) and SLC (C107) model names in a variety of names indicating the displacement of the engines.
The R107/SL was a two-seat convertible with a detachable roof. It replaced the W113 SL-Class in 1971 and was replaced by the R129 SL-Class in 1989.
The predecessor W113 was notably successful in North America, with 19,440 units (40%) of 48,912 total units sold in the US. The R107 and C107 were even more focused on the American market, with specialized engines, bumper designs, headlights, and emissions management designs. The R107 and C107 sold 204,373 units in the US (68%) of 300,175 total units sold (excluding grey market sales into the US).
During its production run, the SL was the only roadster offered by Mercedes-Benz. The C107/SLC was a four-seat car with a fixed roof and an optional sliding steel sunroof. It replaced the W111 Coupé in 1971 and was in turn replaced by the C126 S-class coupé in 1981.

Common 2020 Mercedes-benz Sl450 problems
The Mercedes-Benz SL450, introduced in 2020, has been praised for its reliability, with a low number of reported issues. However, there are a few common problems that owners have experienced, primarily related to the engine and electrical systems.
- Battery Drain Issues: Some SL450 owners have reported rapid battery drains, even when the vehicle is not in use. This issue appears to be related to the car's numerous electronic features, such as Wi-Fi, Bluetooth, and interior lights. To prevent the battery from draining, owners must turn off these features and store the key fob at least 15 feet away from the vehicle. This problem is more prevalent in the AMG SL 55 variant, but it has also been reported in the SL450.
- Engine Issues: Although the M276 engine used in the SL450 is generally reliable, some owners have reported issues with the timing chain tensioner and camshaft position sensor. These problems can lead to engine misfires, rough idling, and reduced performance. Replacing the affected components typically resolves these issues.
- Navigations System Problems: Some SL450 owners have experienced difficulties with the vehicle's navigation system, which may not recognize valid addresses when input manually or when imported via Bluetooth from an Android phone. This issue can be particularly frustrating for those who rely heavily on their car's navigation system.
- Electrical and Software Glitches: A few SL450 owners have reported various electrical and software glitches, such as automatic braking system faults, GPS system failures, and unavailable cameras. These issues may require a dealership visit for resetting the computer or other troubleshooting measures.
- Quality Control Issues: Some owners have reported quality control issues with the S450, such as problems with the Easy Entry/Exit feature requiring frequent shop visits and a dysfunctional navigation system that the dealer could not fix. These issues may be more prevalent in certain production batches or regions.
Despite these common problems, the Mercedes-Benz SL450 has been generally well-regarded for its reliability and performance. Addressing these issues through regular maintenance and timely repairs can help ensure a positive ownership experience.
