Suspension
64 of the 289 complaints (22%) mention the suspension. Suspension wear shows up as clunks, pulling and uneven tires. We inspect shocks, struts, bushings and joints and align the car after repairs. See our suspension & alignment page.
Air Bags
44 of the 289 complaints (15%) mention airbags and seat belts. Airbag and restraint issues are often tied to open safety recalls, which are repaired by the manufacturer at no cost to you. Check your VIN on NHTSA's recall lookup first, and we can help with related warning lights and diagnostics. See our auto repair page.
Electrical System
38 of the 289 complaints (13%) mention the electrical system. Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.

Most Common Mercedes-Benz R-Class Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the R-Class. The most-cited is P0016 (crankshaft and camshaft position correlation (bank 1 sensor a)), mentioned in 4 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| P0016 | Crankshaft and camshaft position correlation (bank 1 sensor A) Can point to a stretched timing chain, a failing sensor or a timing component problem. | 4 |
| P0017 | Crankshaft and camshaft position correlation (bank 1 sensor B) Similar to P0016: timing chain, sensor or timing component trouble. | 3 |
A code is a clue, not a diagnosis. The same code can have several causes, so we test before replacing parts. See our check engine light diagnostics, and read whether it is safe to drive with the check engine light on.
Serious Incident Reports
Of the NHTSA complaints on file for the R-Class, 6 involved a crash, 21 involved a fire, 13 reported injuries. These numbers are drawn from self-reported complaints and are not verified findings. If your vehicle has an open recall, get it repaired promptly.
Keeping a Mercedes-Benz R-Class Reliable in Phoenix
Arizona heat is the hardest test a Mercedes-Benz will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a R-Class that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for R-Class owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Mercedes-Benz R-Class, a pre-purchase inspection shows what the paperwork does not.
