Defect. Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2015 CLS 400 and CLS 400 4matic, 2012-2015 CLS 550 and CLS 550 4matic, 2012-2013 CLS 63, 2014 CLS 63, and 2014-2015 CLS 63P.

Risk. Reduced rear side marker illumination may prevent other drivers from seeing the vehicle, increasing the risk of a crash.

The car started showing a low coolant message around 2017 about twice a year. I felt it was too often the message would come up. I would too off coolant each time to address it without seeing any leaks ever under the car. then 2018 thru 2019 the message would appear about 3 or 4.times per year. had it checked by Mercedes service and they advised nothing was leaking from the car and found no codes indicating urgency in repair to address. my car started failing to turnover after cranking and in July 2021 it failed to turnover at all ever again. took it to the factory sego r dealer and they examined the car for repair from 7/2021 to 12/2021 when they gave it back to me. after getting me to authorize $8,000 in repair cost to get it to turnover, and must needless repair, they advised it needs a new engine. it don't take $8,000 in repair to tell someone their cats needs a new engine. So that was unfortunate. furthermore the nhtsa issued a memo stating the coolant leaks into the engine oil compartment as a known issue until production date 12/2013. my cars production date was 10/2013. the dealer failed to include addressing the known issues stated in the memo 7/2021 to address the timing case and the cylinder case if the coolant system would not pressurize, which my car did not and the known issue that was overlooked in both identifying and repairing per the memo were ignored and I was asked to pay $8,000 in December 2021 to get the car back and be told it needs a new engine, despit

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
